   1CONFIGURATION FILE
   2------------------
   3
   4The Git configuration file contains a number of variables that affect
   5the Git commands' behavior. The `.git/config` file in each repository
   6is used to store the configuration for that repository, and
   7`$HOME/.gitconfig` is used to store a per-user configuration as
   8fallback values for the `.git/config` file. The file `/etc/gitconfig`
   9can be used to store a system-wide default configuration.
  10
  11The configuration variables are used by both the Git plumbing
  12and the porcelains. The variables are divided into sections, wherein
  13the fully qualified variable name of the variable itself is the last
  14dot-separated segment and the section name is everything before the last
  15dot. The variable names are case-insensitive, allow only alphanumeric
  16characters and `-`, and must start with an alphabetic character.  Some
  17variables may appear multiple times; we say then that the variable is
  18multivalued.
  19
  20Syntax
  21~~~~~~
  22
  23The syntax is fairly flexible and permissive; whitespaces are mostly
  24ignored.  The '#' and ';' characters begin comments to the end of line,
  25blank lines are ignored.
  26
  27The file consists of sections and variables.  A section begins with
  28the name of the section in square brackets and continues until the next
  29section begins.  Section names are case-insensitive.  Only alphanumeric
  30characters, `-` and `.` are allowed in section names.  Each variable
  31must belong to some section, which means that there must be a section
  32header before the first setting of a variable.
  33
  34Sections can be further divided into subsections.  To begin a subsection
  35put its name in double quotes, separated by space from the section name,
  36in the section header, like in the example below:
  37
  38--------
  39        [section "subsection"]
  40
  41--------
  42
  43Subsection names are case sensitive and can contain any characters except
  44newline and the null byte. Doublequote `"` and backslash can be included
  45by escaping them as `\"` and `\\`, respectively. Backslashes preceding
  46other characters are dropped when reading; for example, `\t` is read as
  47`t` and `\0` is read as `0` Section headers cannot span multiple lines.
  48Variables may belong directly to a section or to a given subsection. You
  49can have `[section]` if you have `[section "subsection"]`, but you don't
  50need to.
  51
  52There is also a deprecated `[section.subsection]` syntax. With this
  53syntax, the subsection name is converted to lower-case and is also
  54compared case sensitively. These subsection names follow the same
  55restrictions as section names.
  56
  57All the other lines (and the remainder of the line after the section
  58header) are recognized as setting variables, in the form
  59'name = value' (or just 'name', which is a short-hand to say that
  60the variable is the boolean "true").
  61The variable names are case-insensitive, allow only alphanumeric characters
  62and `-`, and must start with an alphabetic character.
  63
  64A line that defines a value can be continued to the next line by
  65ending it with a `\`; the backquote and the end-of-line are
  66stripped.  Leading whitespaces after 'name =', the remainder of the
  67line after the first comment character '#' or ';', and trailing
  68whitespaces of the line are discarded unless they are enclosed in
  69double quotes.  Internal whitespaces within the value are retained
  70verbatim.
  71
  72Inside double quotes, double quote `"` and backslash `\` characters
  73must be escaped: use `\"` for `"` and `\\` for `\`.
  74
  75The following escape sequences (beside `\"` and `\\`) are recognized:
  76`\n` for newline character (NL), `\t` for horizontal tabulation (HT, TAB)
  77and `\b` for backspace (BS).  Other char escape sequences (including octal
  78escape sequences) are invalid.
  79
  80
  81Includes
  82~~~~~~~~
  83
  84The `include` and `includeIf` sections allow you to include config
  85directives from another source. These sections behave identically to
  86each other with the exception that `includeIf` sections may be ignored
  87if their condition does not evaluate to true; see "Conditional includes"
  88below.
  89
  90You can include a config file from another by setting the special
  91`include.path` (or `includeIf.*.path`) variable to the name of the file
  92to be included. The variable takes a pathname as its value, and is
  93subject to tilde expansion. These variables can be given multiple times.
  94
  95The contents of the included file are inserted immediately, as if they
  96had been found at the location of the include directive. If the value of the
  97variable is a relative path, the path is considered to
  98be relative to the configuration file in which the include directive
  99was found.  See below for examples.
 100
 101Conditional includes
 102~~~~~~~~~~~~~~~~~~~~
 103
 104You can include a config file from another conditionally by setting a
 105`includeIf.<condition>.path` variable to the name of the file to be
 106included.
 107
 108The condition starts with a keyword followed by a colon and some data
 109whose format and meaning depends on the keyword. Supported keywords
 110are:
 111
 112`gitdir`::
 113
 114        The data that follows the keyword `gitdir:` is used as a glob
 115        pattern. If the location of the .git directory matches the
 116        pattern, the include condition is met.
 117+
 118The .git location may be auto-discovered, or come from `$GIT_DIR`
 119environment variable. If the repository is auto discovered via a .git
 120file (e.g. from submodules, or a linked worktree), the .git location
 121would be the final location where the .git directory is, not where the
 122.git file is.
 123+
 124The pattern can contain standard globbing wildcards and two additional
 125ones, `**/` and `/**`, that can match multiple path components. Please
 126refer to linkgit:gitignore[5] for details. For convenience:
 127
 128 * If the pattern starts with `~/`, `~` will be substituted with the
 129   content of the environment variable `HOME`.
 130
 131 * If the pattern starts with `./`, it is replaced with the directory
 132   containing the current config file.
 133
 134 * If the pattern does not start with either `~/`, `./` or `/`, `**/`
 135   will be automatically prepended. For example, the pattern `foo/bar`
 136   becomes `**/foo/bar` and would match `/any/path/to/foo/bar`.
 137
 138 * If the pattern ends with `/`, `**` will be automatically added. For
 139   example, the pattern `foo/` becomes `foo/**`. In other words, it
 140   matches "foo" and everything inside, recursively.
 141
 142`gitdir/i`::
 143        This is the same as `gitdir` except that matching is done
 144        case-insensitively (e.g. on case-insensitive file sytems)
 145
 146A few more notes on matching via `gitdir` and `gitdir/i`:
 147
 148 * Symlinks in `$GIT_DIR` are not resolved before matching.
 149
 150 * Both the symlink & realpath versions of paths will be matched
 151   outside of `$GIT_DIR`. E.g. if ~/git is a symlink to
 152   /mnt/storage/git, both `gitdir:~/git` and `gitdir:/mnt/storage/git`
 153   will match.
 154+
 155This was not the case in the initial release of this feature in
 156v2.13.0, which only matched the realpath version. Configuration that
 157wants to be compatible with the initial release of this feature needs
 158to either specify only the realpath version, or both versions.
 159
 160 * Note that "../" is not special and will match literally, which is
 161   unlikely what you want.

 206                path = foo.inc
 207
 208Values
 209~~~~~~
 210
 211Values of many variables are treated as a simple string, but there
 212are variables that take values of specific types and there are rules
 213as to how to spell them.
 214
 215boolean::
 216
 217       When a variable is said to take a boolean value, many
 218       synonyms are accepted for 'true' and 'false'; these are all
 219       case-insensitive.
 220
 221        true;; Boolean true literals are `yes`, `on`, `true`,
 222                and `1`.  Also, a variable defined without `= <value>`
 223                is taken as true.
 224
 225        false;; Boolean false literals are `no`, `off`, `false`,
 226                `0` and the empty string.
 227+
 228When converting a value to its canonical form using the `--type=bool` type
 229specifier, 'git config' will ensure that the output is "true" or
 230"false" (spelled in lowercase).
 231
 232integer::
 233       The value for many variables that specify various sizes can
 234       be suffixed with `k`, `M`,... to mean "scale the number by
 235       1024", "by 1024x1024", etc.
 236
 237color::
 238       The value for a variable that takes a color is a list of
 239       colors (at most two, one for foreground and one for background)
 240       and attributes (as many as you want), separated by spaces.
 241+
 242The basic colors accepted are `normal`, `black`, `red`, `green`, `yellow`,
 243`blue`, `magenta`, `cyan` and `white`.  The first color given is the
 244foreground; the second is the background.
 245+
 246Colors may also be given as numbers between 0 and 255; these use ANSI
 247256-color mode (but note that not all terminals may support this).  If
 248your terminal supports it, you may also specify 24-bit RGB values as
 249hex, like `#ff0ab3`.
 250+
 251The accepted attributes are `bold`, `dim`, `ul`, `blink`, `reverse`,
 252`italic`, and `strike` (for crossed-out or "strikethrough" letters).
 253The position of any attributes with respect to the colors
 254(before, after, or in between), doesn't matter. Specific attributes may
 255be turned off by prefixing them with `no` or `no-` (e.g., `noreverse`,
 256`no-ul`, etc).
 257+
 258An empty color string produces no color effect at all. This can be used
 259to avoid coloring specific elements without disabling color entirely.
 260+
 261For git's pre-defined color slots, the attributes are meant to be reset
 262at the beginning of each item in the colored output. So setting
 263`color.decorate.branch` to `black` will paint that branch name in a
 264plain `black`, even if the previous thing on the same output line (e.g.
 265opening parenthesis before the list of branch names in `log --decorate`
 266output) is set to be painted with `bold` or some other attribute.
 267However, custom log formats may do more complicated and layered
 268coloring, and the negated forms may be useful there.
 269
 270pathname::
 271        A variable that takes a pathname value can be given a
 272        string that begins with "`~/`" or "`~user/`", and the usual
 273        tilde expansion happens to such a string: `~/`
 274        is expanded to the value of `$HOME`, and `~user/` to the
 275        specified user's home directory.
 276
 277
 278Variables
 279~~~~~~~~~
 280
 281Note that this list is non-comprehensive and not necessarily complete.
 282For command-specific variables, you will find a more detailed description
 283in the appropriate manual page.
 284
 285Other git-related tools may and do use their own variables.  When
 286inventing new variables for use in your own tool, make sure their
 287names do not conflict with those that are used by Git itself and
 288other popular tools, and describe them in your documentation.
 289
 290
 291advice.*::
 292        These variables control various optional help messages designed to
 293        aid new users. All 'advice.*' variables default to 'true', and you
 294        can tell Git that you do not need help by setting these to 'false':
 295+
 296--
 297        pushUpdateRejected::
 298                Set this variable to 'false' if you want to disable
 299                'pushNonFFCurrent',
 300                'pushNonFFMatching', 'pushAlreadyExists',
 301                'pushFetchFirst', and 'pushNeedsForce'
 302                simultaneously.
 303        pushNonFFCurrent::
 304                Advice shown when linkgit:git-push[1] fails due to a
 305                non-fast-forward update to the current branch.
 306        pushNonFFMatching::
 307                Advice shown when you ran linkgit:git-push[1] and pushed
 308                'matching refs' explicitly (i.e. you used ':', or
 309                specified a refspec that isn't your current branch) and
 310                it resulted in a non-fast-forward error.
 311        pushAlreadyExists::
 312                Shown when linkgit:git-push[1] rejects an update that
 313                does not qualify for fast-forwarding (e.g., a tag.)
 314        pushFetchFirst::
 315                Shown when linkgit:git-push[1] rejects an update that
 316                tries to overwrite a remote ref that points at an
 317                object we do not have.
 318        pushNeedsForce::
 319                Shown when linkgit:git-push[1] rejects an update that
 320                tries to overwrite a remote ref that points at an
 321                object that is not a commit-ish, or make the remote
 322                ref point at an object that is not a commit-ish.
 323        statusHints::
 324                Show directions on how to proceed from the current
 325                state in the output of linkgit:git-status[1], in
 326                the template shown when writing commit messages in
 327                linkgit:git-commit[1], and in the help message shown
 328                by linkgit:git-checkout[1] when switching branch.
 329        statusUoption::
 330                Advise to consider using the `-u` option to linkgit:git-status[1]
 331                when the command takes more than 2 seconds to enumerate untracked
 332                files.
 333        commitBeforeMerge::
 334                Advice shown when linkgit:git-merge[1] refuses to
 335                merge to avoid overwriting local changes.
 336        resolveConflict::
 337                Advice shown by various commands when conflicts
 338                prevent the operation from being performed.
 339        implicitIdentity::
 340                Advice on how to set your identity configuration when
 341                your information is guessed from the system username and
 342                domain name.
 343        detachedHead::
 344                Advice shown when you used linkgit:git-checkout[1] to
 345                move to the detach HEAD state, to instruct how to create
 346                a local branch after the fact.
 347        checkoutAmbiguousRemoteBranchName::
 348                Advice shown when the argument to
 349                linkgit:git-checkout[1] ambiguously resolves to a
 350                remote tracking branch on more than one remote in
 351                situations where an unambiguous argument would have
 352                otherwise caused a remote-tracking branch to be
 353                checked out. See the `checkout.defaultRemote`
 354                configuration variable for how to set a given remote
 355                to used by default in some situations where this
 356                advice would be printed.
 357        amWorkDir::
 358                Advice that shows the location of the patch file when
 359                linkgit:git-am[1] fails to apply it.
 360        rmHints::
 361                In case of failure in the output of linkgit:git-rm[1],
 362                show directions on how to proceed from the current state.
 363        addEmbeddedRepo::
 364                Advice on what to do when you've accidentally added one
 365                git repo inside of another.
 366        ignoredHook::
 367                Advice shown if a hook is ignored because the hook is not
 368                set as executable.
 369        waitingForEditor::
 370                Print a message to the terminal whenever Git is waiting for
 371                editor input from the user.
 372--
 373
 374core.fileMode::
 375        Tells Git if the executable bit of files in the working tree
 376        is to be honored.
 377+
 378Some filesystems lose the executable bit when a file that is
 379marked as executable is checked out, or checks out a
 380non-executable file with executable bit on.
 381linkgit:git-clone[1] or linkgit:git-init[1] probe the filesystem
 382to see if it handles the executable bit correctly
 383and this variable is automatically set as necessary.
 384+
 385A repository, however, may be on a filesystem that handles
 386the filemode correctly, and this variable is set to 'true'
 387when created, but later may be made accessible from another
 388environment that loses the filemode (e.g. exporting ext4 via
 389CIFS mount, visiting a Cygwin created repository with
 390Git for Windows or Eclipse).
 391In such a case it may be necessary to set this variable to 'false'.
 392See linkgit:git-update-index[1].
 393+
 394The default is true (when core.filemode is not specified in the config file).
 395
 396core.hideDotFiles::
 397        (Windows-only) If true, mark newly-created directories and files whose
 398        name starts with a dot as hidden.  If 'dotGitOnly', only the `.git/`
 399        directory is hidden, but no other files starting with a dot.  The
 400        default mode is 'dotGitOnly'.
 401
 402core.ignoreCase::
 403        Internal variable which enables various workarounds to enable
 404        Git to work better on filesystems that are not case sensitive,
 405        like APFS, HFS+, FAT, NTFS, etc. For example, if a directory listing
 406        finds "makefile" when Git expects "Makefile", Git will assume
 407        it is really the same file, and continue to remember it as
 408        "Makefile".
 409+
 410The default is false, except linkgit:git-clone[1] or linkgit:git-init[1]
 411will probe and set core.ignoreCase true if appropriate when the repository
 412is created.
 413+
 414Git relies on the proper configuration of this variable for your operating
 415and file system. Modifying this value may result in unexpected behavior.
 416
 417core.precomposeUnicode::
 418        This option is only used by Mac OS implementation of Git.
 419        When core.precomposeUnicode=true, Git reverts the unicode decomposition
 420        of filenames done by Mac OS. This is useful when sharing a repository
 421        between Mac OS and Linux or Windows.
 422        (Git for Windows 1.7.10 or higher is needed, or Git under cygwin 1.7).
 423        When false, file names are handled fully transparent by Git,
 424        which is backward compatible with older versions of Git.
 425
 426core.protectHFS::
 427        If set to true, do not allow checkout of paths that would
 428        be considered equivalent to `.git` on an HFS+ filesystem.
 429        Defaults to `true` on Mac OS, and `false` elsewhere.
 430
 431core.protectNTFS::
 432        If set to true, do not allow checkout of paths that would
 433        cause problems with the NTFS filesystem, e.g. conflict with
 434        8.3 "short" names.
 435        Defaults to `true` on Windows, and `false` elsewhere.
 436
 437core.fsmonitor::
 438        If set, the value of this variable is used as a command which
 439        will identify all files that may have changed since the
 440        requested date/time. This information is used to speed up git by
 441        avoiding unnecessary processing of files that have not changed.
 442        See the "fsmonitor-watchman" section of linkgit:githooks[5].
 443
 444core.trustctime::
 445        If false, the ctime differences between the index and the
 446        working tree are ignored; useful when the inode change time
 447        is regularly modified by something outside Git (file system
 448        crawlers and some backup systems).
 449        See linkgit:git-update-index[1]. True by default.
 450
 451core.splitIndex::
 452        If true, the split-index feature of the index will be used.
 453        See linkgit:git-update-index[1]. False by default.
 454
 455core.untrackedCache::
 456        Determines what to do about the untracked cache feature of the
 457        index. It will be kept, if this variable is unset or set to
 458        `keep`. It will automatically be added if set to `true`. And
 459        it will automatically be removed, if set to `false`. Before
 460        setting it to `true`, you should check that mtime is working
 461        properly on your system.
 462        See linkgit:git-update-index[1]. `keep` by default.
 463
 464core.checkStat::
 465        When missing or is set to `default`, many fields in the stat
 466        structure are checked to detect if a file has been modified
 467        since Git looked at it.  When this configuration variable is
 468        set to `minimal`, sub-second part of mtime and ctime, the
 469        uid and gid of the owner of the file, the inode number (and
 470        the device number, if Git was compiled to use it), are
 471        excluded from the check among these fields, leaving only the
 472        whole-second part of mtime (and ctime, if `core.trustCtime`
 473        is set) and the filesize to be checked.
 474+
 475There are implementations of Git that do not leave usable values in
 476some fields (e.g. JGit); by excluding these fields from the
 477comparison, the `minimal` mode may help interoperability when the
 478same repository is used by these other systems at the same time.
 479
 480core.quotePath::
 481        Commands that output paths (e.g. 'ls-files', 'diff'), will
 482        quote "unusual" characters in the pathname by enclosing the
 483        pathname in double-quotes and escaping those characters with
 484        backslashes in the same way C escapes control characters (e.g.
 485        `\t` for TAB, `\n` for LF, `\\` for backslash) or bytes with
 486        values larger than 0x80 (e.g. octal `\302\265` for "micro" in
 487        UTF-8).  If this variable is set to false, bytes higher than
 488        0x80 are not considered "unusual" any more. Double-quotes,
 489        backslash and control characters are always escaped regardless
 490        of the setting of this variable.  A simple space character is
 491        not considered "unusual".  Many commands can output pathnames
 492        completely verbatim using the `-z` option. The default value
 493        is true.
 494
 495core.eol::
 496        Sets the line ending type to use in the working directory for
 497        files that have the `text` property set when core.autocrlf is false.
 498        Alternatives are 'lf', 'crlf' and 'native', which uses the platform's
 499        native line ending.  The default value is `native`.  See
 500        linkgit:gitattributes[5] for more information on end-of-line
 501        conversion.
 502
 503core.safecrlf::
 504        If true, makes Git check if converting `CRLF` is reversible when
 505        end-of-line conversion is active.  Git will verify if a command
 506        modifies a file in the work tree either directly or indirectly.
 507        For example, committing a file followed by checking out the
 508        same file should yield the original file in the work tree.  If
 509        this is not the case for the current setting of
 510        `core.autocrlf`, Git will reject the file.  The variable can
 511        be set to "warn", in which case Git will only warn about an
 512        irreversible conversion but continue the operation.
 513+
 514CRLF conversion bears a slight chance of corrupting data.
 515When it is enabled, Git will convert CRLF to LF during commit and LF to
 516CRLF during checkout.  A file that contains a mixture of LF and
 517CRLF before the commit cannot be recreated by Git.  For text
 518files this is the right thing to do: it corrects line endings
 519such that we have only LF line endings in the repository.
 520But for binary files that are accidentally classified as text the
 521conversion can corrupt data.
 522+
 523If you recognize such corruption early you can easily fix it by
 524setting the conversion type explicitly in .gitattributes.  Right
 525after committing you still have the original file in your work
 526tree and this file is not yet corrupted.  You can explicitly tell
 527Git that this file is binary and Git will handle the file
 528appropriately.
 529+
 530Unfortunately, the desired effect of cleaning up text files with
 531mixed line endings and the undesired effect of corrupting binary
 532files cannot be distinguished.  In both cases CRLFs are removed
 533in an irreversible way.  For text files this is the right thing
 534to do because CRLFs are line endings, while for binary files
 535converting CRLFs corrupts data.
 536+
 537Note, this safety check does not mean that a checkout will generate a
 538file identical to the original file for a different setting of
 539`core.eol` and `core.autocrlf`, but only for the current one.  For
 540example, a text file with `LF` would be accepted with `core.eol=lf`
 541and could later be checked out with `core.eol=crlf`, in which case the
 542resulting file would contain `CRLF`, although the original file
 543contained `LF`.  However, in both work trees the line endings would be
 544consistent, that is either all `LF` or all `CRLF`, but never mixed.  A
 545file with mixed line endings would be reported by the `core.safecrlf`
 546mechanism.
 547
 548core.autocrlf::
 549        Setting this variable to "true" is the same as setting
 550        the `text` attribute to "auto" on all files and core.eol to "crlf".
 551        Set to true if you want to have `CRLF` line endings in your
 552        working directory and the repository has LF line endings.
 553        This variable can be set to 'input',
 554        in which case no output conversion is performed.
 555
 556core.checkRoundtripEncoding::
 557        A comma and/or whitespace separated list of encodings that Git
 558        performs UTF-8 round trip checks on if they are used in an
 559        `working-tree-encoding` attribute (see linkgit:gitattributes[5]).
 560        The default value is `SHIFT-JIS`.
 561
 562core.symlinks::
 563        If false, symbolic links are checked out as small plain files that
 564        contain the link text. linkgit:git-update-index[1] and
 565        linkgit:git-add[1] will not change the recorded type to regular
 566        file. Useful on filesystems like FAT that do not support
 567        symbolic links.
 568+
 569The default is true, except linkgit:git-clone[1] or linkgit:git-init[1]
 570will probe and set core.symlinks false if appropriate when the repository
 571is created.
 572
 573core.gitProxy::
 574        A "proxy command" to execute (as 'command host port') instead
 575        of establishing direct connection to the remote server when
 576        using the Git protocol for fetching. If the variable value is
 577        in the "COMMAND for DOMAIN" format, the command is applied only
 578        on hostnames ending with the specified domain string. This variable
 579        may be set multiple times and is matched in the given order;
 580        the first match wins.
 581+
 582Can be overridden by the `GIT_PROXY_COMMAND` environment variable
 583(which always applies universally, without the special "for"
 584handling).
 585+
 586The special string `none` can be used as the proxy command to
 587specify that no proxy be used for a given domain pattern.
 588This is useful for excluding servers inside a firewall from
 589proxy use, while defaulting to a common proxy for external domains.
 590
 591core.sshCommand::
 592        If this variable is set, `git fetch` and `git push` will
 593        use the specified command instead of `ssh` when they need to
 594        connect to a remote system. The command is in the same form as
 595        the `GIT_SSH_COMMAND` environment variable and is overridden
 596        when the environment variable is set.
 597
 598core.ignoreStat::
 599        If true, Git will avoid using lstat() calls to detect if files have
 600        changed by setting the "assume-unchanged" bit for those tracked files
 601        which it has updated identically in both the index and working tree.
 602+
 603When files are modified outside of Git, the user will need to stage
 604the modified files explicitly (e.g. see 'Examples' section in
 605linkgit:git-update-index[1]).
 606Git will not normally detect changes to those files.
 607+
 608This is useful on systems where lstat() calls are very slow, such as
 609CIFS/Microsoft Windows.
 610+
 611False by default.
 612
 613core.preferSymlinkRefs::
 614        Instead of the default "symref" format for HEAD
 615        and other symbolic reference files, use symbolic links.
 616        This is sometimes needed to work with old scripts that
 617        expect HEAD to be a symbolic link.
 618
 619core.alternateRefsCommand::
 620        When advertising tips of available history from an alternate, use the shell to
 621        execute the specified command instead of linkgit:git-for-each-ref[1]. The
 622        first argument is the absolute path of the alternate. Output must contain one
 623        hex object id per line (i.e., the same as produced by `git for-each-ref
 624        --format='%(objectname)'`).
 625+
 626Note that you cannot generally put `git for-each-ref` directly into the config
 627value, as it does not take a repository path as an argument (but you can wrap
 628the command above in a shell script).
 629
 630core.alternateRefsPrefixes::
 631        When listing references from an alternate, list only references that begin
 632        with the given prefix. Prefixes match as if they were given as arguments to
 633        linkgit:git-for-each-ref[1]. To list multiple prefixes, separate them with
 634        whitespace. If `core.alternateRefsCommand` is set, setting
 635        `core.alternateRefsPrefixes` has no effect.
 636
 637core.bare::
 638        If true this repository is assumed to be 'bare' and has no
 639        working directory associated with it.  If this is the case a
 640        number of commands that require a working directory will be
 641        disabled, such as linkgit:git-add[1] or linkgit:git-merge[1].
 642+
 643This setting is automatically guessed by linkgit:git-clone[1] or
 644linkgit:git-init[1] when the repository was created.  By default a
 645repository that ends in "/.git" is assumed to be not bare (bare =
 646false), while all other repositories are assumed to be bare (bare
 647= true).
 648
 649core.worktree::
 650        Set the path to the root of the working tree.
 651        If `GIT_COMMON_DIR` environment variable is set, core.worktree
 652        is ignored and not used for determining the root of working tree.
 653        This can be overridden by the `GIT_WORK_TREE` environment
 654        variable and the `--work-tree` command-line option.
 655        The value can be an absolute path or relative to the path to
 656        the .git directory, which is either specified by --git-dir
 657        or GIT_DIR, or automatically discovered.
 658        If --git-dir or GIT_DIR is specified but none of
 659        --work-tree, GIT_WORK_TREE and core.worktree is specified,
 660        the current working directory is regarded as the top level
 661        of your working tree.
 662+
 663Note that this variable is honored even when set in a configuration
 664file in a ".git" subdirectory of a directory and its value differs
 665from the latter directory (e.g. "/path/to/.git/config" has
 666core.worktree set to "/different/path"), which is most likely a
 667misconfiguration.  Running Git commands in the "/path/to" directory will
 668still use "/different/path" as the root of the work tree and can cause
 669confusion unless you know what you are doing (e.g. you are creating a
 670read-only snapshot of the same index to a location different from the
 671repository's usual working tree).
 672
 673core.logAllRefUpdates::
 674        Enable the reflog. Updates to a ref <ref> is logged to the file
 675        "`$GIT_DIR/logs/<ref>`", by appending the new and old
 676        SHA-1, the date/time and the reason of the update, but
 677        only when the file exists.  If this configuration
 678        variable is set to `true`, missing "`$GIT_DIR/logs/<ref>`"
 679        file is automatically created for branch heads (i.e. under
 680        `refs/heads/`), remote refs (i.e. under `refs/remotes/`),
 681        note refs (i.e. under `refs/notes/`), and the symbolic ref `HEAD`.
 682        If it is set to `always`, then a missing reflog is automatically
 683        created for any ref under `refs/`.
 684+
 685This information can be used to determine what commit
 686was the tip of a branch "2 days ago".
 687+
 688This value is true by default in a repository that has
 689a working directory associated with it, and false by
 690default in a bare repository.
 691
 692core.repositoryFormatVersion::
 693        Internal variable identifying the repository format and layout
 694        version.
 695
 696core.sharedRepository::
 697        When 'group' (or 'true'), the repository is made shareable between
 698        several users in a group (making sure all the files and objects are
 699        group-writable). When 'all' (or 'world' or 'everybody'), the
 700        repository will be readable by all users, additionally to being
 701        group-shareable. When 'umask' (or 'false'), Git will use permissions
 702        reported by umask(2). When '0xxx', where '0xxx' is an octal number,
 703        files in the repository will have this mode value. '0xxx' will override
 704        user's umask value (whereas the other options will only override
 705        requested parts of the user's umask value). Examples: '0660' will make
 706        the repo read/write-able for the owner and group, but inaccessible to
 707        others (equivalent to 'group' unless umask is e.g. '0022'). '0640' is a
 708        repository that is group-readable but not group-writable.
 709        See linkgit:git-init[1]. False by default.
 710
 711core.warnAmbiguousRefs::
 712        If true, Git will warn you if the ref name you passed it is ambiguous
 713        and might match multiple refs in the repository. True by default.
 714
 715core.compression::
 716        An integer -1..9, indicating a default compression level.
 717        -1 is the zlib default. 0 means no compression,
 718        and 1..9 are various speed/size tradeoffs, 9 being slowest.
 719        If set, this provides a default to other compression variables,
 720        such as `core.looseCompression` and `pack.compression`.
 721
 722core.looseCompression::
 723        An integer -1..9, indicating the compression level for objects that
 724        are not in a pack file. -1 is the zlib default. 0 means no
 725        compression, and 1..9 are various speed/size tradeoffs, 9 being
 726        slowest.  If not set,  defaults to core.compression.  If that is
 727        not set,  defaults to 1 (best speed).
 728
 729core.packedGitWindowSize::
 730        Number of bytes of a pack file to map into memory in a
 731        single mapping operation.  Larger window sizes may allow
 732        your system to process a smaller number of large pack files
 733        more quickly.  Smaller window sizes will negatively affect
 734        performance due to increased calls to the operating system's
 735        memory manager, but may improve performance when accessing
 736        a large number of large pack files.
 737+
 738Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
 739MiB on 32 bit platforms and 1 GiB on 64 bit platforms.  This should
 740be reasonable for all users/operating systems.  You probably do
 741not need to adjust this value.
 742+
 743Common unit suffixes of 'k', 'm', or 'g' are supported.
 744
 745core.packedGitLimit::
 746        Maximum number of bytes to map simultaneously into memory
 747        from pack files.  If Git needs to access more than this many
 748        bytes at once to complete an operation it will unmap existing
 749        regions to reclaim virtual address space within the process.
 750+
 751Default is 256 MiB on 32 bit platforms and 32 TiB (effectively
 752unlimited) on 64 bit platforms.
 753This should be reasonable for all users/operating systems, except on
 754the largest projects.  You probably do not need to adjust this value.
 755+
 756Common unit suffixes of 'k', 'm', or 'g' are supported.
 757
 758core.deltaBaseCacheLimit::
 759        Maximum number of bytes to reserve for caching base objects
 760        that may be referenced by multiple deltified objects.  By storing the
 761        entire decompressed base objects in a cache Git is able
 762        to avoid unpacking and decompressing frequently used base
 763        objects multiple times.
 764+
 765Default is 96 MiB on all platforms.  This should be reasonable
 766for all users/operating systems, except on the largest projects.
 767You probably do not need to adjust this value.
 768+
 769Common unit suffixes of 'k', 'm', or 'g' are supported.
 770
 771core.bigFileThreshold::
 772        Files larger than this size are stored deflated, without
 773        attempting delta compression.  Storing large files without
 774        delta compression avoids excessive memory usage, at the
 775        slight expense of increased disk usage. Additionally files
 776        larger than this size are always treated as binary.
 777+
 778Default is 512 MiB on all platforms.  This should be reasonable
 779for most projects as source code and other text files can still
 780be delta compressed, but larger binary media files won't be.
 781+
 782Common unit suffixes of 'k', 'm', or 'g' are supported.
 783
 784core.excludesFile::
 785        Specifies the pathname to the file that contains patterns to
 786        describe paths that are not meant to be tracked, in addition
 787        to '.gitignore' (per-directory) and '.git/info/exclude'.
 788        Defaults to `$XDG_CONFIG_HOME/git/ignore`.
 789        If `$XDG_CONFIG_HOME` is either not set or empty, `$HOME/.config/git/ignore`
 790        is used instead. See linkgit:gitignore[5].
 791
 792core.askPass::
 793        Some commands (e.g. svn and http interfaces) that interactively
 794        ask for a password can be told to use an external program given
 795        via the value of this variable. Can be overridden by the `GIT_ASKPASS`
 796        environment variable. If not set, fall back to the value of the
 797        `SSH_ASKPASS` environment variable or, failing that, a simple password
 798        prompt. The external program shall be given a suitable prompt as
 799        command-line argument and write the password on its STDOUT.
 800
 801core.attributesFile::
 802        In addition to '.gitattributes' (per-directory) and
 803        '.git/info/attributes', Git looks into this file for attributes
 804        (see linkgit:gitattributes[5]). Path expansions are made the same
 805        way as for `core.excludesFile`. Its default value is
 806        `$XDG_CONFIG_HOME/git/attributes`. If `$XDG_CONFIG_HOME` is either not
 807        set or empty, `$HOME/.config/git/attributes` is used instead.
 808
 809core.hooksPath::
 810        By default Git will look for your hooks in the
 811        '$GIT_DIR/hooks' directory. Set this to different path,
 812        e.g. '/etc/git/hooks', and Git will try to find your hooks in
 813        that directory, e.g. '/etc/git/hooks/pre-receive' instead of
 814        in '$GIT_DIR/hooks/pre-receive'.
 815+
 816The path can be either absolute or relative. A relative path is
 817taken as relative to the directory where the hooks are run (see
 818the "DESCRIPTION" section of linkgit:githooks[5]).
 819+
 820This configuration variable is useful in cases where you'd like to
 821centrally configure your Git hooks instead of configuring them on a
 822per-repository basis, or as a more flexible and centralized
 823alternative to having an `init.templateDir` where you've changed
 824default hooks.
 825
 826core.editor::
 827        Commands such as `commit` and `tag` that let you edit
 828        messages by launching an editor use the value of this
 829        variable when it is set, and the environment variable
 830        `GIT_EDITOR` is not set.  See linkgit:git-var[1].
 831
 832core.commentChar::
 833        Commands such as `commit` and `tag` that let you edit
 834        messages consider a line that begins with this character
 835        commented, and removes them after the editor returns
 836        (default '#').
 837+
 838If set to "auto", `git-commit` would select a character that is not
 839the beginning character of any line in existing commit messages.
 840
 841core.filesRefLockTimeout::
 842        The length of time, in milliseconds, to retry when trying to
 843        lock an individual reference. Value 0 means not to retry at
 844        all; -1 means to try indefinitely. Default is 100 (i.e.,
 845        retry for 100ms).
 846
 847core.packedRefsTimeout::
 848        The length of time, in milliseconds, to retry when trying to
 849        lock the `packed-refs` file. Value 0 means not to retry at
 850        all; -1 means to try indefinitely. Default is 1000 (i.e.,
 851        retry for 1 second).
 852
 853core.pager::
 854        Text viewer for use by Git commands (e.g., 'less').  The value
 855        is meant to be interpreted by the shell.  The order of preference
 856        is the `$GIT_PAGER` environment variable, then `core.pager`
 857        configuration, then `$PAGER`, and then the default chosen at
 858        compile time (usually 'less').
 859+
 860When the `LESS` environment variable is unset, Git sets it to `FRX`
 861(if `LESS` environment variable is set, Git does not change it at
 862all).  If you want to selectively override Git's default setting
 863for `LESS`, you can set `core.pager` to e.g. `less -S`.  This will
 864be passed to the shell by Git, which will translate the final
 865command to `LESS=FRX less -S`. The environment does not set the
 866`S` option but the command line does, instructing less to truncate
 867long lines. Similarly, setting `core.pager` to `less -+F` will
 868deactivate the `F` option specified by the environment from the
 869command-line, deactivating the "quit if one screen" behavior of
 870`less`.  One can specifically activate some flags for particular
 871commands: for example, setting `pager.blame` to `less -S` enables
 872line truncation only for `git blame`.
 873+
 874Likewise, when the `LV` environment variable is unset, Git sets it
 875to `-c`.  You can override this setting by exporting `LV` with
 876another value or setting `core.pager` to `lv +c`.
 877
 878core.whitespace::
 879        A comma separated list of common whitespace problems to
 880        notice.  'git diff' will use `color.diff.whitespace` to
 881        highlight them, and 'git apply --whitespace=error' will
 882        consider them as errors.  You can prefix `-` to disable
 883        any of them (e.g. `-trailing-space`):
 884+
 885* `blank-at-eol` treats trailing whitespaces at the end of the line
 886  as an error (enabled by default).
 887* `space-before-tab` treats a space character that appears immediately
 888  before a tab character in the initial indent part of the line as an
 889  error (enabled by default).
 890* `indent-with-non-tab` treats a line that is indented with space
 891  characters instead of the equivalent tabs as an error (not enabled by
 892  default).
 893* `tab-in-indent` treats a tab character in the initial indent part of
 894  the line as an error (not enabled by default).
 895* `blank-at-eof` treats blank lines added at the end of file as an error
 896  (enabled by default).
 897* `trailing-space` is a short-hand to cover both `blank-at-eol` and
 898  `blank-at-eof`.
 899* `cr-at-eol` treats a carriage-return at the end of line as
 900  part of the line terminator, i.e. with it, `trailing-space`
 901  does not trigger if the character before such a carriage-return
 902  is not a whitespace (not enabled by default).
 903* `tabwidth=<n>` tells how many character positions a tab occupies; this
 904  is relevant for `indent-with-non-tab` and when Git fixes `tab-in-indent`
 905  errors. The default tab width is 8. Allowed values are 1 to 63.
 906
 907core.fsyncObjectFiles::
 908        This boolean will enable 'fsync()' when writing object files.
 909+
 910This is a total waste of time and effort on a filesystem that orders
 911data writes properly, but can be useful for filesystems that do not use
 912journalling (traditional UNIX filesystems) or that only journal metadata
 913and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback").
 914
 915core.preloadIndex::
 916        Enable parallel index preload for operations like 'git diff'
 917+
 918This can speed up operations like 'git diff' and 'git status' especially
 919on filesystems like NFS that have weak caching semantics and thus
 920relatively high IO latencies.  When enabled, Git will do the
 921index comparison to the filesystem data in parallel, allowing
 922overlapping IO's.  Defaults to true.
 923
 924core.unsetenvvars::
 925        Windows-only: comma-separated list of environment variables'
 926        names that need to be unset before spawning any other process.
 927        Defaults to `PERL5LIB` to account for the fact that Git for
 928        Windows insists on using its own Perl interpreter.
 929
 930core.createObject::
 931        You can set this to 'link', in which case a hardlink followed by
 932        a delete of the source are used to make sure that object creation
 933        will not overwrite existing objects.
 934+
 935On some file system/operating system combinations, this is unreliable.
 936Set this config setting to 'rename' there; However, This will remove the
 937check that makes sure that existing object files will not get overwritten.
 938
 939core.notesRef::
 940        When showing commit messages, also show notes which are stored in
 941        the given ref.  The ref must be fully qualified.  If the given
 942        ref does not exist, it is not an error but means that no
 943        notes should be printed.
 944+
 945This setting defaults to "refs/notes/commits", and it can be overridden by
 946the `GIT_NOTES_REF` environment variable.  See linkgit:git-notes[1].
 947
 948core.commitGraph::
 949        If true, then git will read the commit-graph file (if it exists)
 950        to parse the graph structure of commits. Defaults to false. See
 951        linkgit:git-commit-graph[1] for more information.
 952
 953core.useReplaceRefs::
 954        If set to `false`, behave as if the `--no-replace-objects`
 955        option was given on the command line. See linkgit:git[1] and
 956        linkgit:git-replace[1] for more information.
 957
 958core.multiPackIndex::
 959        Use the multi-pack-index file to track multiple packfiles using a
 960        single index. See link:technical/multi-pack-index.html[the
 961        multi-pack-index design document].
 962
 963core.sparseCheckout::
 964        Enable "sparse checkout" feature. See section "Sparse checkout" in
 965        linkgit:git-read-tree[1] for more information.
 966
 967core.abbrev::
 968        Set the length object names are abbreviated to.  If
 969        unspecified or set to "auto", an appropriate value is
 970        computed based on the approximate number of packed objects
 971        in your repository, which hopefully is enough for
 972        abbreviated object names to stay unique for some time.
 973        The minimum length is 4.
 974
 975add.ignoreErrors::
 976add.ignore-errors (deprecated)::
 977        Tells 'git add' to continue adding files when some files cannot be
 978        added due to indexing errors. Equivalent to the `--ignore-errors`
 979        option of linkgit:git-add[1].  `add.ignore-errors` is deprecated,
 980        as it does not follow the usual naming convention for configuration
 981        variables.
 982
 983alias.*::
 984        Command aliases for the linkgit:git[1] command wrapper - e.g.
 985        after defining "alias.last = cat-file commit HEAD", the invocation
 986        "git last" is equivalent to "git cat-file commit HEAD". To avoid
 987        confusion and troubles with script usage, aliases that
 988        hide existing Git commands are ignored. Arguments are split by
 989        spaces, the usual shell quoting and escaping is supported.
 990        A quote pair or a backslash can be used to quote them.
 991+
 992If the alias expansion is prefixed with an exclamation point,
 993it will be treated as a shell command.  For example, defining
 994"alias.new = !gitk --all --not ORIG_HEAD", the invocation
 995"git new" is equivalent to running the shell command
 996"gitk --all --not ORIG_HEAD".  Note that shell commands will be
 997executed from the top-level directory of a repository, which may
 998not necessarily be the current directory.
 999`GIT_PREFIX` is set as returned by running 'git rev-parse --show-prefix'
1000from the original current directory. See linkgit:git-rev-parse[1].
1001
1002am.keepcr::
1003        If true, git-am will call git-mailsplit for patches in mbox format
1004        with parameter `--keep-cr`. In this case git-mailsplit will
1005        not remove `\r` from lines ending with `\r\n`. Can be overridden
1006        by giving `--no-keep-cr` from the command line.
1007        See linkgit:git-am[1], linkgit:git-mailsplit[1].
1008
1009am.threeWay::
1010        By default, `git am` will fail if the patch does not apply cleanly. When
1011        set to true, this setting tells `git am` to fall back on 3-way merge if
1012        the patch records the identity of blobs it is supposed to apply to and
1013        we have those blobs available locally (equivalent to giving the `--3way`
1014        option from the command line). Defaults to `false`.
1015        See linkgit:git-am[1].
1016
1017apply.ignoreWhitespace::
1018        When set to 'change', tells 'git apply' to ignore changes in
1019        whitespace, in the same way as the `--ignore-space-change`
1020        option.
1021        When set to one of: no, none, never, false tells 'git apply' to
1022        respect all whitespace differences.
1023        See linkgit:git-apply[1].
1024
1025apply.whitespace::
1026        Tells 'git apply' how to handle whitespaces, in the same way
1027        as the `--whitespace` option. See linkgit:git-apply[1].
1028
1029blame.blankBoundary::
1030        Show blank commit object name for boundary commits in
1031        linkgit:git-blame[1]. This option defaults to false.
1032
1033blame.coloring::
1034        This determines the coloring scheme to be applied to blame
1035        output. It can be 'repeatedLines', 'highlightRecent',
1036        or 'none' which is the default.
1037
1038blame.date::
1039        Specifies the format used to output dates in linkgit:git-blame[1].
1040        If unset the iso format is used. For supported values,
1041        see the discussion of the `--date` option at linkgit:git-log[1].
1042
1043blame.showEmail::
1044        Show the author email instead of author name in linkgit:git-blame[1].
1045        This option defaults to false.
1046
1047blame.showRoot::
1048        Do not treat root commits as boundaries in linkgit:git-blame[1].
1049        This option defaults to false.
1050
1051branch.autoSetupMerge::
1052        Tells 'git branch' and 'git checkout' to set up new branches
1053        so that linkgit:git-pull[1] will appropriately merge from the
1054        starting point branch. Note that even if this option is not set,
1055        this behavior can be chosen per-branch using the `--track`
1056        and `--no-track` options. The valid settings are: `false` -- no
1057        automatic setup is done; `true` -- automatic setup is done when the
1058        starting point is a remote-tracking branch; `always` --
1059        automatic setup is done when the starting point is either a
1060        local branch or remote-tracking
1061        branch. This option defaults to true.
1062
1063branch.autoSetupRebase::
1064        When a new branch is created with 'git branch' or 'git checkout'
1065        that tracks another branch, this variable tells Git to set
1066        up pull to rebase instead of merge (see "branch.<name>.rebase").
1067        When `never`, rebase is never automatically set to true.
1068        When `local`, rebase is set to true for tracked branches of
1069        other local branches.
1070        When `remote`, rebase is set to true for tracked branches of
1071        remote-tracking branches.
1072        When `always`, rebase will be set to true for all tracking
1073        branches.
1074        See "branch.autoSetupMerge" for details on how to set up a
1075        branch to track another branch.
1076        This option defaults to never.
1077
1078branch.sort::
1079        This variable controls the sort ordering of branches when displayed by
1080        linkgit:git-branch[1]. Without the "--sort=<value>" option provided, the
1081        value of this variable will be used as the default.
1082        See linkgit:git-for-each-ref[1] field names for valid values.
1083
1084branch.<name>.remote::
1085        When on branch <name>, it tells 'git fetch' and 'git push'
1086        which remote to fetch from/push to.  The remote to push to
1087        may be overridden with `remote.pushDefault` (for all branches).
1088        The remote to push to, for the current branch, may be further
1089        overridden by `branch.<name>.pushRemote`.  If no remote is
1090        configured, or if you are not on any branch, it defaults to
1091        `origin` for fetching and `remote.pushDefault` for pushing.
1092        Additionally, `.` (a period) is the current local repository
1093        (a dot-repository), see `branch.<name>.merge`'s final note below.
1094
1095branch.<name>.pushRemote::
1096        When on branch <name>, it overrides `branch.<name>.remote` for
1097        pushing.  It also overrides `remote.pushDefault` for pushing
1098        from branch <name>.  When you pull from one place (e.g. your
1099        upstream) and push to another place (e.g. your own publishing
1100        repository), you would want to set `remote.pushDefault` to
1101        specify the remote to push to for all branches, and use this
1102        option to override it for a specific branch.
1103
1104branch.<name>.merge::
1105        Defines, together with branch.<name>.remote, the upstream branch
1106        for the given branch. It tells 'git fetch'/'git pull'/'git rebase' which
1107        branch to merge and can also affect 'git push' (see push.default).
1108        When in branch <name>, it tells 'git fetch' the default
1109        refspec to be marked for merging in FETCH_HEAD. The value is
1110        handled like the remote part of a refspec, and must match a
1111        ref which is fetched from the remote given by
1112        "branch.<name>.remote".
1113        The merge information is used by 'git pull' (which at first calls
1114        'git fetch') to lookup the default branch for merging. Without
1115        this option, 'git pull' defaults to merge the first refspec fetched.
1116        Specify multiple values to get an octopus merge.
1117        If you wish to setup 'git pull' so that it merges into <name> from
1118        another branch in the local repository, you can point
1119        branch.<name>.merge to the desired branch, and use the relative path
1120        setting `.` (a period) for branch.<name>.remote.
1121
1122branch.<name>.mergeOptions::
1123        Sets default options for merging into branch <name>. The syntax and
1124        supported options are the same as those of linkgit:git-merge[1], but
1125        option values containing whitespace characters are currently not
1126        supported.
1127
1128branch.<name>.rebase::
1129        When true, rebase the branch <name> on top of the fetched branch,
1130        instead of merging the default branch from the default remote when
1131        "git pull" is run. See "pull.rebase" for doing this in a non
1132        branch-specific manner.
1133+
1134When `merges`, pass the `--rebase-merges` option to 'git rebase'
1135so that the local merge commits are included in the rebase (see
1136linkgit:git-rebase[1] for details).
1137+
1138When preserve, also pass `--preserve-merges` along to 'git rebase'
1139so that locally committed merge commits will not be flattened
1140by running 'git pull'.
1141+
1142When the value is `interactive`, the rebase is run in interactive mode.
1143+
1144*NOTE*: this is a possibly dangerous operation; do *not* use
1145it unless you understand the implications (see linkgit:git-rebase[1]
1146for details).
1147
1148branch.<name>.description::
1149        Branch description, can be edited with
1150        `git branch --edit-description`. Branch description is
1151        automatically added in the format-patch cover letter or
1152        request-pull summary.
1153
1154browser.<tool>.cmd::
1155        Specify the command to invoke the specified browser. The
1156        specified command is evaluated in shell with the URLs passed
1157        as arguments. (See linkgit:git-web{litdd}browse[1].)
1158
1159browser.<tool>.path::
1160        Override the path for the given tool that may be used to
1161        browse HTML help (see `-w` option in linkgit:git-help[1]) or a
1162        working repository in gitweb (see linkgit:git-instaweb[1]).
1163
1164checkout.defaultRemote::
1165        When you run 'git checkout <something>' and only have one
1166        remote, it may implicitly fall back on checking out and
1167        tracking e.g. 'origin/<something>'. This stops working as soon
1168        as you have more than one remote with a '<something>'
1169        reference. This setting allows for setting the name of a
1170        preferred remote that should always win when it comes to
1171        disambiguation. The typical use-case is to set this to
1172        `origin`.
1173+
1174Currently this is used by linkgit:git-checkout[1] when 'git checkout
1175<something>' will checkout the '<something>' branch on another remote,
1176and by linkgit:git-worktree[1] when 'git worktree add' refers to a
1177remote branch. This setting might be used for other checkout-like
1178commands or functionality in the future.
1179
1180checkout.optimizeNewBranch::
1181        Optimizes the performance of "git checkout -b <new_branch>" when
1182        using sparse-checkout.  When set to true, git will not update the
1183        repo based on the current sparse-checkout settings.  This means it
1184        will not update the skip-worktree bit in the index nor add/remove
1185        files in the working directory to reflect the current sparse checkout
1186        settings nor will it show the local changes.
1187
1188clean.requireForce::
1189        A boolean to make git-clean do nothing unless given -f,
1190        -i or -n.   Defaults to true.
1191
1192color.advice::
1193        A boolean to enable/disable color in hints (e.g. when a push
1194        failed, see `advice.*` for a list).  May be set to `always`,
1195        `false` (or `never`) or `auto` (or `true`), in which case colors
1196        are used only when the error output goes to a terminal. If
1197        unset, then the value of `color.ui` is used (`auto` by default).
1198
1199color.advice.hint::
1200        Use customized color for hints.
1201
1202color.blame.highlightRecent::
1203        This can be used to color the metadata of a blame line depending
1204        on age of the line.
1205+
1206This setting should be set to a comma-separated list of color and date settings,
1207starting and ending with a color, the dates should be set from oldest to newest.
1208The metadata will be colored given the colors if the the line was introduced
1209before the given timestamp, overwriting older timestamped colors.
1210+
1211Instead of an absolute timestamp relative timestamps work as well, e.g.
12122.weeks.ago is valid to address anything older than 2 weeks.
1213+
1214It defaults to 'blue,12 month ago,white,1 month ago,red', which colors
1215everything older than one year blue, recent changes between one month and
1216one year old are kept white, and lines introduced within the last month are
1217colored red.
1218
1219color.blame.repeatedLines::
1220        Use the customized color for the part of git-blame output that
1221        is repeated meta information per line (such as commit id,
1222        author name, date and timezone). Defaults to cyan.
1223
1224color.branch::
1225        A boolean to enable/disable color in the output of
1226        linkgit:git-branch[1]. May be set to `always`,
1227        `false` (or `never`) or `auto` (or `true`), in which case colors are used
1228        only when the output is to a terminal. If unset, then the
1229        value of `color.ui` is used (`auto` by default).
1230
1231color.branch.<slot>::
1232        Use customized color for branch coloration. `<slot>` is one of
1233        `current` (the current branch), `local` (a local branch),
1234        `remote` (a remote-tracking branch in refs/remotes/),
1235        `upstream` (upstream tracking branch), `plain` (other
1236        refs).
1237
1238color.diff::
1239        Whether to use ANSI escape sequences to add color to patches.
1240        If this is set to `always`, linkgit:git-diff[1],
1241        linkgit:git-log[1], and linkgit:git-show[1] will use color
1242        for all patches.  If it is set to `true` or `auto`, those
1243        commands will only use color when output is to the terminal.
1244        If unset, then the value of `color.ui` is used (`auto` by
1245        default).
1246+
1247This does not affect linkgit:git-format-patch[1] or the
1248'git-diff-{asterisk}' plumbing commands.  Can be overridden on the
1249command line with the `--color[=<when>]` option.
1250
1251color.diff.<slot>::
1252        Use customized color for diff colorization.  `<slot>` specifies
1253        which part of the patch to use the specified color, and is one
1254        of `context` (context text - `plain` is a historical synonym),
1255        `meta` (metainformation), `frag`
1256        (hunk header), 'func' (function in hunk header), `old` (removed lines),
1257        `new` (added lines), `commit` (commit headers), `whitespace`
1258        (highlighting whitespace errors), `oldMoved` (deleted lines),
1259        `newMoved` (added lines), `oldMovedDimmed`, `oldMovedAlternative`,
1260        `oldMovedAlternativeDimmed`, `newMovedDimmed`, `newMovedAlternative`
1261        `newMovedAlternativeDimmed` (See the '<mode>'
1262        setting of '--color-moved' in linkgit:git-diff[1] for details),
1263        `contextDimmed`, `oldDimmed`, `newDimmed`, `contextBold`,
1264        `oldBold`, and `newBold` (see linkgit:git-range-diff[1] for details).
1265
1266color.decorate.<slot>::
1267        Use customized color for 'git log --decorate' output.  `<slot>` is one
1268        of `branch`, `remoteBranch`, `tag`, `stash` or `HEAD` for local
1269        branches, remote-tracking branches, tags, stash and HEAD, respectively
1270        and `grafted` for grafted commits.
1271
1272color.grep::
1273        When set to `always`, always highlight matches.  When `false` (or
1274        `never`), never.  When set to `true` or `auto`, use color only
1275        when the output is written to the terminal.  If unset, then the
1276        value of `color.ui` is used (`auto` by default).
1277
1278color.grep.<slot>::
1279        Use customized color for grep colorization.  `<slot>` specifies which
1280        part of the line to use the specified color, and is one of
1281+
1282--
1283`context`;;
1284        non-matching text in context lines (when using `-A`, `-B`, or `-C`)
1285`filename`;;
1286        filename prefix (when not using `-h`)
1287`function`;;
1288        function name lines (when using `-p`)
1289`lineNumber`;;
1290        line number prefix (when using `-n`)
1291`column`;;
1292        column number prefix (when using `--column`)
1293`match`;;
1294        matching text (same as setting `matchContext` and `matchSelected`)
1295`matchContext`;;
1296        matching text in context lines
1297`matchSelected`;;
1298        matching text in selected lines
1299`selected`;;
1300        non-matching text in selected lines
1301`separator`;;
1302        separators between fields on a line (`:`, `-`, and `=`)
1303        and between hunks (`--`)
1304--
1305
1306color.interactive::
1307        When set to `always`, always use colors for interactive prompts
1308        and displays (such as those used by "git-add --interactive" and
1309        "git-clean --interactive"). When false (or `never`), never.
1310        When set to `true` or `auto`, use colors only when the output is
1311        to the terminal. If unset, then the value of `color.ui` is
1312        used (`auto` by default).
1313
1314color.interactive.<slot>::
1315        Use customized color for 'git add --interactive' and 'git clean
1316        --interactive' output. `<slot>` may be `prompt`, `header`, `help`
1317        or `error`, for four distinct types of normal output from
1318        interactive commands.
1319
1320color.pager::
1321        A boolean to enable/disable colored output when the pager is in
1322        use (default is true).
1323
1324color.push::
1325        A boolean to enable/disable color in push errors. May be set to
1326        `always`, `false` (or `never`) or `auto` (or `true`), in which
1327        case colors are used only when the error output goes to a terminal.
1328        If unset, then the value of `color.ui` is used (`auto` by default).
1329
1330color.push.error::
1331        Use customized color for push errors.
1332
1333color.remote::
1334        If set, keywords at the start of the line are highlighted. The
1335        keywords are "error", "warning", "hint" and "success", and are
1336        matched case-insensitively. May be set to `always`, `false` (or
1337        `never`) or `auto` (or `true`). If unset, then the value of
1338        `color.ui` is used (`auto` by default).
1339
1340color.remote.<slot>::
1341        Use customized color for each remote keyword. `<slot>` may be
1342        `hint`, `warning`, `success` or `error` which match the
1343        corresponding keyword.
1344
1345color.showBranch::
1346        A boolean to enable/disable color in the output of
1347        linkgit:git-show-branch[1]. May be set to `always`,
1348        `false` (or `never`) or `auto` (or `true`), in which case colors are used
1349        only when the output is to a terminal. If unset, then the
1350        value of `color.ui` is used (`auto` by default).
1351
1352color.status::
1353        A boolean to enable/disable color in the output of
1354        linkgit:git-status[1]. May be set to `always`,
1355        `false` (or `never`) or `auto` (or `true`), in which case colors are used
1356        only when the output is to a terminal. If unset, then the
1357        value of `color.ui` is used (`auto` by default).
1358
1359color.status.<slot>::
1360        Use customized color for status colorization. `<slot>` is
1361        one of `header` (the header text of the status message),
1362        `added` or `updated` (files which are added but not committed),
1363        `changed` (files which are changed but not added in the index),
1364        `untracked` (files which are not tracked by Git),
1365        `branch` (the current branch),
1366        `nobranch` (the color the 'no branch' warning is shown in, defaulting
1367        to red),
1368        `localBranch` or `remoteBranch` (the local and remote branch names,
1369        respectively, when branch and tracking information is displayed in the
1370        status short-format), or
1371        `unmerged` (files which have unmerged changes).
1372
1373color.transport::
1374        A boolean to enable/disable color when pushes are rejected. May be
1375        set to `always`, `false` (or `never`) or `auto` (or `true`), in which
1376        case colors are used only when the error output goes to a terminal.
1377        If unset, then the value of `color.ui` is used (`auto` by default).
1378
1379color.transport.rejected::
1380        Use customized color when a push was rejected.
1381
1382color.ui::
1383        This variable determines the default value for variables such
1384        as `color.diff` and `color.grep` that control the use of color
1385        per command family. Its scope will expand as more commands learn
1386        configuration to set a default for the `--color` option.  Set it
1387        to `false` or `never` if you prefer Git commands not to use
1388        color unless enabled explicitly with some other configuration
1389        or the `--color` option. Set it to `always` if you want all
1390        output not intended for machine consumption to use color, to
1391        `true` or `auto` (this is the default since Git 1.8.4) if you
1392        want such output to use color when written to the terminal.
1393
1394column.ui::
1395        Specify whether supported commands should output in columns.
1396        This variable consists of a list of tokens separated by spaces
1397        or commas:
1398+
1399These options control when the feature should be enabled
1400(defaults to 'never'):
1401+
1402--
1403`always`;;
1404        always show in columns
1405`never`;;
1406        never show in columns
1407`auto`;;
1408        show in columns if the output is to the terminal
1409--
1410+
1411These options control layout (defaults to 'column').  Setting any
1412of these implies 'always' if none of 'always', 'never', or 'auto' are
1413specified.
1414+
1415--
1416`column`;;
1417        fill columns before rows
1418`row`;;
1419        fill rows before columns
1420`plain`;;
1421        show in one column
1422--
1423+
1424Finally, these options can be combined with a layout option (defaults
1425to 'nodense'):
1426+
1427--
1428`dense`;;
1429        make unequal size columns to utilize more space
1430`nodense`;;
1431        make equal size columns
1432--
1433
1434column.branch::
1435        Specify whether to output branch listing in `git branch` in columns.
1436        See `column.ui` for details.
1437
1438column.clean::
1439        Specify the layout when list items in `git clean -i`, which always
1440        shows files and directories in columns. See `column.ui` for details.
1441
1442column.status::
1443        Specify whether to output untracked files in `git status` in columns.
1444        See `column.ui` for details.
1445
1446column.tag::
1447        Specify whether to output tag listing in `git tag` in columns.
1448        See `column.ui` for details.
1449
1450commit.cleanup::
1451        This setting overrides the default of the `--cleanup` option in
1452        `git commit`. See linkgit:git-commit[1] for details. Changing the
1453        default can be useful when you always want to keep lines that begin
1454        with comment character `#` in your log message, in which case you
1455        would do `git config commit.cleanup whitespace` (note that you will
1456        have to remove the help lines that begin with `#` in the commit log
1457        template yourself, if you do this).
1458
1459commit.gpgSign::
1460
1461        A boolean to specify whether all commits should be GPG signed.
1462        Use of this option when doing operations such as rebase can
1463        result in a large number of commits being signed. It may be
1464        convenient to use an agent to avoid typing your GPG passphrase
1465        several times.
1466
1467commit.status::
1468        A boolean to enable/disable inclusion of status information in the
1469        commit message template when using an editor to prepare the commit
1470        message.  Defaults to true.
1471
1472commit.template::
1473        Specify the pathname of a file to use as the template for
1474        new commit messages.
1475
1476commit.verbose::
1477        A boolean or int to specify the level of verbose with `git commit`.
1478        See linkgit:git-commit[1].
1479
1480credential.helper::
1481        Specify an external helper to be called when a username or
1482        password credential is needed; the helper may consult external
1483        storage to avoid prompting the user for the credentials. Note
1484        that multiple helpers may be defined. See linkgit:gitcredentials[7]
1485        for details.
1486
1487credential.useHttpPath::
1488        When acquiring credentials, consider the "path" component of an http
1489        or https URL to be important. Defaults to false. See
1490        linkgit:gitcredentials[7] for more information.
1491
1492credential.username::
1493        If no username is set for a network authentication, use this username
1494        by default. See credential.<context>.* below, and
1495        linkgit:gitcredentials[7].
1496
1497credential.<url>.*::
1498        Any of the credential.* options above can be applied selectively to
1499        some credentials. For example "credential.https://example.com.username"
1500        would set the default username only for https connections to
1501        example.com. See linkgit:gitcredentials[7] for details on how URLs are
1502        matched.
1503
1504credentialCache.ignoreSIGHUP::
1505        Tell git-credential-cache--daemon to ignore SIGHUP, instead of quitting.
1506
1507completion.commands::
1508        This is only used by git-completion.bash to add or remove
1509        commands from the list of completed commands. Normally only
1510        porcelain commands and a few select others are completed. You
1511        can add more commands, separated by space, in this
1512        variable. Prefixing the command with '-' will remove it from
1513        the existing list.
1514
1515include::diff-config.txt[]
1516
1517difftool.<tool>.path::
1518        Override the path for the given tool.  This is useful in case
1519        your tool is not in the PATH.
1520
1521difftool.<tool>.cmd::
1522        Specify the command to invoke the specified diff tool.
1523        The specified command is evaluated in shell with the following
1524        variables available:  'LOCAL' is set to the name of the temporary
1525        file containing the contents of the diff pre-image and 'REMOTE'
1526        is set to the name of the temporary file containing the contents
1527        of the diff post-image.
1528
1529difftool.prompt::
1530        Prompt before each invocation of the diff tool.
1531
1532fastimport.unpackLimit::
1533        If the number of objects imported by linkgit:git-fast-import[1]
1534        is below this limit, then the objects will be unpacked into
1535        loose object files.  However if the number of imported objects
1536        equals or exceeds this limit then the pack will be stored as a
1537        pack.  Storing the pack from a fast-import can make the import
1538        operation complete faster, especially on slow filesystems.  If
1539        not set, the value of `transfer.unpackLimit` is used instead.
1540
1541include::fetch-config.txt[]
1542
1543include::format-config.txt[]
1544
1545filter.<driver>.clean::
1546        The command which is used to convert the content of a worktree
1547        file to a blob upon checkin.  See linkgit:gitattributes[5] for
1548        details.
1549
1550filter.<driver>.smudge::
1551        The command which is used to convert the content of a blob
1552        object to a worktree file upon checkout.  See
1553        linkgit:gitattributes[5] for details.
1554
1555fsck.<msg-id>::
1556        During fsck git may find issues with legacy data which
1557        wouldn't be generated by current versions of git, and which
1558        wouldn't be sent over the wire if `transfer.fsckObjects` was
1559        set. This feature is intended to support working with legacy
1560        repositories containing such data.
1561+
1562Setting `fsck.<msg-id>` will be picked up by linkgit:git-fsck[1], but
1563to accept pushes of such data set `receive.fsck.<msg-id>` instead, or
1564to clone or fetch it set `fetch.fsck.<msg-id>`.
1565+
1566The rest of the documentation discusses `fsck.*` for brevity, but the
1567same applies for the corresponding `receive.fsck.*` and
1568`fetch.<msg-id>.*`. variables.
1569+
1570Unlike variables like `color.ui` and `core.editor` the
1571`receive.fsck.<msg-id>` and `fetch.fsck.<msg-id>` variables will not
1572fall back on the `fsck.<msg-id>` configuration if they aren't set. To
1573uniformly configure the same fsck settings in different circumstances
1574all three of them they must all set to the same values.
1575+
1576When `fsck.<msg-id>` is set, errors can be switched to warnings and
1577vice versa by configuring the `fsck.<msg-id>` setting where the
1578`<msg-id>` is the fsck message ID and the value is one of `error`,
1579`warn` or `ignore`. For convenience, fsck prefixes the error/warning
1580with the message ID, e.g. "missingEmail: invalid author/committer line
1581- missing email" means that setting `fsck.missingEmail = ignore` will
1582hide that issue.
1583+
1584In general, it is better to enumerate existing objects with problems
1585with `fsck.skipList`, instead of listing the kind of breakages these
1586problematic objects share to be ignored, as doing the latter will
1587allow new instances of the same breakages go unnoticed.
1588+
1589Setting an unknown `fsck.<msg-id>` value will cause fsck to die, but
1590doing the same for `receive.fsck.<msg-id>` and `fetch.fsck.<msg-id>`
1591will only cause git to warn.
1592
1593fsck.skipList::
1594        The path to a list of object names (i.e. one unabbreviated SHA-1 per
1595        line) that are known to be broken in a non-fatal way and should
1596        be ignored. On versions of Git 2.20 and later comments ('#'), empty
1597        lines, and any leading and trailing whitespace is ignored. Everything
1598        but a SHA-1 per line will error out on older versions.
1599+
1600This feature is useful when an established project should be accepted
1601despite early commits containing errors that can be safely ignored
1602such as invalid committer email addresses.  Note: corrupt objects
1603cannot be skipped with this setting.
1604+
1605Like `fsck.<msg-id>` this variable has corresponding
1606`receive.fsck.skipList` and `fetch.fsck.skipList` variants.
1607+
1608Unlike variables like `color.ui` and `core.editor` the
1609`receive.fsck.skipList` and `fetch.fsck.skipList` variables will not
1610fall back on the `fsck.skipList` configuration if they aren't set. To
1611uniformly configure the same fsck settings in different circumstances
1612all three of them they must all set to the same values.
1613+
1614Older versions of Git (before 2.20) documented that the object names
1615list should be sorted. This was never a requirement, the object names
1616could appear in any order, but when reading the list we tracked whether
1617the list was sorted for the purposes of an internal binary search
1618implementation, which could save itself some work with an already sorted
1619list. Unless you had a humongous list there was no reason to go out of
1620your way to pre-sort the list. After Git version 2.20 a hash implementation
1621is used instead, so there's now no reason to pre-sort the list.
1622
1623gc.aggressiveDepth::
1624        The depth parameter used in the delta compression
1625        algorithm used by 'git gc --aggressive'.  This defaults
1626        to 50.
1627
1628gc.aggressiveWindow::
1629        The window size parameter used in the delta compression
1630        algorithm used by 'git gc --aggressive'.  This defaults
1631        to 250.
1632
1633gc.auto::
1634        When there are approximately more than this many loose
1635        objects in the repository, `git gc --auto` will pack them.
1636        Some Porcelain commands use this command to perform a
1637        light-weight garbage collection from time to time.  The
1638        default value is 6700.  Setting this to 0 disables it.
1639
1640gc.autoPackLimit::
1641        When there are more than this many packs that are not
1642        marked with `*.keep` file in the repository, `git gc
1643        --auto` consolidates them into one larger pack.  The
1644        default value is 50.  Setting this to 0 disables it.
1645
1646gc.autoDetach::
1647        Make `git gc --auto` return immediately and run in background
1648        if the system supports it. Default is true.
1649
1650gc.bigPackThreshold::
1651        If non-zero, all packs larger than this limit are kept when
1652        `git gc` is run. This is very similar to `--keep-base-pack`
1653        except that all packs that meet the threshold are kept, not
1654        just the base pack. Defaults to zero. Common unit suffixes of
1655        'k', 'm', or 'g' are supported.
1656+
1657Note that if the number of kept packs is more than gc.autoPackLimit,
1658this configuration variable is ignored, all packs except the base pack
1659will be repacked. After this the number of packs should go below
1660gc.autoPackLimit and gc.bigPackThreshold should be respected again.
1661
1662gc.writeCommitGraph::
1663        If true, then gc will rewrite the commit-graph file when
1664        linkgit:git-gc[1] is run. When using linkgit:git-gc[1]
1665        '--auto' the commit-graph will be updated if housekeeping is
1666        required. Default is false. See linkgit:git-commit-graph[1]
1667        for details.
1668
1669gc.logExpiry::
1670        If the file gc.log exists, then `git gc --auto` will print
1671        its content and exit with status zero instead of running
1672        unless that file is more than 'gc.logExpiry' old.  Default is
1673        "1.day".  See `gc.pruneExpire` for more ways to specify its
1674        value.
1675
1676gc.packRefs::
1677        Running `git pack-refs` in a repository renders it
1678        unclonable by Git versions prior to 1.5.1.2 over dumb
1679        transports such as HTTP.  This variable determines whether
1680        'git gc' runs `git pack-refs`. This can be set to `notbare`
1681        to enable it within all non-bare repos or it can be set to a
1682        boolean value.  The default is `true`.
1683
1684gc.pruneExpire::
1685        When 'git gc' is run, it will call 'prune --expire 2.weeks.ago'.
1686        Override the grace period with this config variable.  The value
1687        "now" may be used to disable this grace period and always prune
1688        unreachable objects immediately, or "never" may be used to
1689        suppress pruning.  This feature helps prevent corruption when
1690        'git gc' runs concurrently with another process writing to the
1691        repository; see the "NOTES" section of linkgit:git-gc[1].
1692
1693gc.worktreePruneExpire::
1694        When 'git gc' is run, it calls
1695        'git worktree prune --expire 3.months.ago'.
1696        This config variable can be used to set a different grace
1697        period. The value "now" may be used to disable the grace
1698        period and prune `$GIT_DIR/worktrees` immediately, or "never"
1699        may be used to suppress pruning.
1700
1701gc.reflogExpire::
1702gc.<pattern>.reflogExpire::
1703        'git reflog expire' removes reflog entries older than
1704        this time; defaults to 90 days. The value "now" expires all
1705        entries immediately, and "never" suppresses expiration
1706        altogether. With "<pattern>" (e.g.
1707        "refs/stash") in the middle the setting applies only to
1708        the refs that match the <pattern>.
1709
1710gc.reflogExpireUnreachable::
1711gc.<pattern>.reflogExpireUnreachable::
1712        'git reflog expire' removes reflog entries older than
1713        this time and are not reachable from the current tip;
1714        defaults to 30 days. The value "now" expires all entries
1715        immediately, and "never" suppresses expiration altogether.
1716        With "<pattern>" (e.g. "refs/stash")
1717        in the middle, the setting applies only to the refs that
1718        match the <pattern>.
1719
1720gc.rerereResolved::
1721        Records of conflicted merge you resolved earlier are
1722        kept for this many days when 'git rerere gc' is run.
1723        You can also use more human-readable "1.month.ago", etc.
1724        The default is 60 days.  See linkgit:git-rerere[1].
1725
1726gc.rerereUnresolved::
1727        Records of conflicted merge you have not resolved are
1728        kept for this many days when 'git rerere gc' is run.
1729        You can also use more human-readable "1.month.ago", etc.
1730        The default is 15 days.  See linkgit:git-rerere[1].

1751grep.lineNumber::
1752        If set to true, enable `-n` option by default.
1753
1754grep.column::
1755        If set to true, enable the `--column` option by default.
1756
1757grep.patternType::
1758        Set the default matching behavior. Using a value of 'basic', 'extended',
1759        'fixed', or 'perl' will enable the `--basic-regexp`, `--extended-regexp`,
1760        `--fixed-strings`, or `--perl-regexp` option accordingly, while the
1761        value 'default' will return to the default matching behavior.
1762
1763grep.extendedRegexp::
1764        If set to true, enable `--extended-regexp` option by default. This
1765        option is ignored when the `grep.patternType` option is set to a value
1766        other than 'default'.
1767
1768grep.threads::
1769        Number of grep worker threads to use.
1770        See `grep.threads` in linkgit:git-grep[1] for more information.
1771
1772grep.fallbackToNoIndex::
1773        If set to true, fall back to git grep --no-index if git grep
1774        is executed outside of a git repository.  Defaults to false.
1775
1776gpg.program::
1777        Use this custom program instead of "`gpg`" found on `$PATH` when
1778        making or verifying a PGP signature. The program must support the
1779        same command-line interface as GPG, namely, to verify a detached
1780        signature, "`gpg --verify $file - <$signature`" is run, and the
1781        program is expected to signal a good signature by exiting with
1782        code 0, and to generate an ASCII-armored detached signature, the
1783        standard input of "`gpg -bsau $key`" is fed with the contents to be
1784        signed, and the program is expected to send the result to its
1785        standard output.
1786
1787gpg.format::
1788        Specifies which key format to use when signing with `--gpg-sign`.
1789        Default is "openpgp" and another possible value is "x509".
1790
1791gpg.<format>.program::
1792        Use this to customize the program used for the signing format you
1793        chose. (see `gpg.program` and `gpg.format`) `gpg.program` can still
1794        be used as a legacy synonym for `gpg.openpgp.program`. The default
1795        value for `gpg.x509.program` is "gpgsm".
1796
1797include::gui-config.txt[]
1798
1799guitool.<name>.cmd::
1800        Specifies the shell command line to execute when the corresponding item
1801        of the linkgit:git-gui[1] `Tools` menu is invoked. This option is
1802        mandatory for every tool. The command is executed from the root of
1803        the working directory, and in the environment it receives the name of
1804        the tool as `GIT_GUITOOL`, the name of the currently selected file as
1805        'FILENAME', and the name of the current branch as 'CUR_BRANCH' (if
1806        the head is detached, 'CUR_BRANCH' is empty).
1807
1808guitool.<name>.needsFile::
1809        Run the tool only if a diff is selected in the GUI. It guarantees
1810        that 'FILENAME' is not empty.
1811
1812guitool.<name>.noConsole::
1813        Run the command silently, without creating a window to display its
1814        output.
1815
1816guitool.<name>.noRescan::
1817        Don't rescan the working directory for changes after the tool
1818        finishes execution.
1819
1820guitool.<name>.confirm::
1821        Show a confirmation dialog before actually running the tool.
1822
1823guitool.<name>.argPrompt::
1824        Request a string argument from the user, and pass it to the tool
1825        through the `ARGS` environment variable. Since requesting an
1826        argument implies confirmation, the 'confirm' option has no effect
1827        if this is enabled. If the option is set to 'true', 'yes', or '1',
1828        the dialog uses a built-in generic prompt; otherwise the exact
1829        value of the variable is used.
1830
1831guitool.<name>.revPrompt::
1832        Request a single valid revision from the user, and set the
1833        `REVISION` environment variable. In other aspects this option
1834        is similar to 'argPrompt', and can be used together with it.
1835
1836guitool.<name>.revUnmerged::
1837        Show only unmerged branches in the 'revPrompt' subdialog.
1838        This is useful for tools similar to merge or rebase, but not
1839        for things like checkout or reset.
1840
1841guitool.<name>.title::
1842        Specifies the title to use for the prompt dialog. The default
1843        is the tool name.
1844
1845guitool.<name>.prompt::
1846        Specifies the general prompt string to display at the top of
1847        the dialog, before subsections for 'argPrompt' and 'revPrompt'.
1848        The default value includes the actual command.
1849
1850help.browser::
1851        Specify the browser that will be used to display help in the
1852        'web' format. See linkgit:git-help[1].
1853
1854help.format::
1855        Override the default help format used by linkgit:git-help[1].
1856        Values 'man', 'info', 'web' and 'html' are supported. 'man' is
1857        the default. 'web' and 'html' are the same.
1858
1859help.autoCorrect::
1860        Automatically correct and execute mistyped commands after
1861        waiting for the given number of deciseconds (0.1 sec). If more
1862        than one command can be deduced from the entered text, nothing
1863        will be executed.  If the value of this option is negative,
1864        the corrected command will be executed immediately. If the
1865        value is 0 - the command will be just shown but not executed.
1866        This is the default.
1867
1868help.htmlPath::
1869        Specify the path where the HTML documentation resides. File system paths
1870        and URLs are supported. HTML pages will be prefixed with this path when
1871        help is displayed in the 'web' format. This defaults to the documentation
1872        path of your Git installation.
1873
1874http.proxy::
1875        Override the HTTP proxy, normally configured using the 'http_proxy',
1876        'https_proxy', and 'all_proxy' environment variables (see `curl(1)`). In
1877        addition to the syntax understood by curl, it is possible to specify a
1878        proxy string with a user name but no password, in which case git will
1879        attempt to acquire one in the same way it does for other credentials. See
1880        linkgit:gitcredentials[7] for more information. The syntax thus is
1881        '[protocol://][user[:password]@]proxyhost[:port]'. This can be overridden
1882        on a per-remote basis; see remote.<name>.proxy
1883
1884http.proxyAuthMethod::
1885        Set the method with which to authenticate against the HTTP proxy. This
1886        only takes effect if the configured proxy string contains a user name part
1887        (i.e. is of the form 'user@host' or 'user@host:port'). This can be
1888        overridden on a per-remote basis; see `remote.<name>.proxyAuthMethod`.
1889        Both can be overridden by the `GIT_HTTP_PROXY_AUTHMETHOD` environment
1890        variable.  Possible values are:
1891+
1892--
1893* `anyauth` - Automatically pick a suitable authentication method. It is
1894  assumed that the proxy answers an unauthenticated request with a 407
1895  status code and one or more Proxy-authenticate headers with supported
1896  authentication methods. This is the default.
1897* `basic` - HTTP Basic authentication
1898* `digest` - HTTP Digest authentication; this prevents the password from being
1899  transmitted to the proxy in clear text
1900* `negotiate` - GSS-Negotiate authentication (compare the --negotiate option
1901  of `curl(1)`)
1902* `ntlm` - NTLM authentication (compare the --ntlm option of `curl(1)`)
1903--
1904
1905http.emptyAuth::
1906        Attempt authentication without seeking a username or password.  This
1907        can be used to attempt GSS-Negotiate authentication without specifying
1908        a username in the URL, as libcurl normally requires a username for
1909        authentication.
1910
1911http.delegation::
1912        Control GSSAPI credential delegation. The delegation is disabled
1913        by default in libcurl since version 7.21.7. Set parameter to tell
1914        the server what it is allowed to delegate when it comes to user
1915        credentials. Used with GSS/kerberos. Possible values are:
1916+
1917--
1918* `none` - Don't allow any delegation.
1919* `policy` - Delegates if and only if the OK-AS-DELEGATE flag is set in the
1920  Kerberos service ticket, which is a matter of realm policy.
1921* `always` - Unconditionally allow the server to delegate.
1922--
1923
1924
1925http.extraHeader::
1926        Pass an additional HTTP header when communicating with a server.  If
1927        more than one such entry exists, all of them are added as extra
1928        headers.  To allow overriding the settings inherited from the system
1929        config, an empty value will reset the extra headers to the empty list.
1930
1931http.cookieFile::
1932        The pathname of a file containing previously stored cookie lines,
1933        which should be used
1934        in the Git http session, if they match the server. The file format
1935        of the file to read cookies from should be plain HTTP headers or
1936        the Netscape/Mozilla cookie file format (see `curl(1)`).
1937        NOTE that the file specified with http.cookieFile is used only as
1938        input unless http.saveCookies is set.
1939
1940http.saveCookies::
1941        If set, store cookies received during requests to the file specified by
1942        http.cookieFile. Has no effect if http.cookieFile is unset.
1943
1944http.sslVersion::
1945        The SSL version to use when negotiating an SSL connection, if you
1946        want to force the default.  The available and default version
1947        depend on whether libcurl was built against NSS or OpenSSL and the
1948        particular configuration of the crypto library in use. Internally
1949        this sets the 'CURLOPT_SSL_VERSION' option; see the libcurl
1950        documentation for more details on the format of this option and
1951        for the ssl version supported. Actually the possible values of
1952        this option are:
1953
1954        - sslv2
1955        - sslv3
1956        - tlsv1
1957        - tlsv1.0
1958        - tlsv1.1
1959        - tlsv1.2
1960        - tlsv1.3
1961
1962+
1963Can be overridden by the `GIT_SSL_VERSION` environment variable.
1964To force git to use libcurl's default ssl version and ignore any
1965explicit http.sslversion option, set `GIT_SSL_VERSION` to the
1966empty string.
1967
1968http.sslCipherList::
1969  A list of SSL ciphers to use when negotiating an SSL connection.
1970  The available ciphers depend on whether libcurl was built against
1971  NSS or OpenSSL and the particular configuration of the crypto
1972  library in use.  Internally this sets the 'CURLOPT_SSL_CIPHER_LIST'
1973  option; see the libcurl documentation for more details on the format
1974  of this list.
1975+
1976Can be overridden by the `GIT_SSL_CIPHER_LIST` environment variable.
1977To force git to use libcurl's default cipher list and ignore any
1978explicit http.sslCipherList option, set `GIT_SSL_CIPHER_LIST` to the
1979empty string.
1980
1981http.sslVerify::
1982        Whether to verify the SSL certificate when fetching or pushing
1983        over HTTPS. Defaults to true. Can be overridden by the
1984        `GIT_SSL_NO_VERIFY` environment variable.
1985
1986http.sslCert::
1987        File containing the SSL certificate when fetching or pushing
1988        over HTTPS. Can be overridden by the `GIT_SSL_CERT` environment
1989        variable.
1990
1991http.sslKey::
1992        File containing the SSL private key when fetching or pushing
1993        over HTTPS. Can be overridden by the `GIT_SSL_KEY` environment
1994        variable.
1995
1996http.sslCertPasswordProtected::
1997        Enable Git's password prompt for the SSL certificate.  Otherwise
1998        OpenSSL will prompt the user, possibly many times, if the
1999        certificate or private key is encrypted.  Can be overridden by the
2000        `GIT_SSL_CERT_PASSWORD_PROTECTED` environment variable.
2001
2002http.sslCAInfo::
2003        File containing the certificates to verify the peer with when
2004        fetching or pushing over HTTPS. Can be overridden by the
2005        `GIT_SSL_CAINFO` environment variable.
2006
2007http.sslCAPath::
2008        Path containing files with the CA certificates to verify the peer
2009        with when fetching or pushing over HTTPS. Can be overridden
2010        by the `GIT_SSL_CAPATH` environment variable.
2011
2012http.pinnedpubkey::
2013        Public key of the https service. It may either be the filename of
2014        a PEM or DER encoded public key file or a string starting with
2015        'sha256//' followed by the base64 encoded sha256 hash of the
2016        public key. See also libcurl 'CURLOPT_PINNEDPUBLICKEY'. git will
2017        exit with an error if this option is set but not supported by
2018        cURL.
2019
2020http.sslTry::
2021        Attempt to use AUTH SSL/TLS and encrypted data transfers
2022        when connecting via regular FTP protocol. This might be needed
2023        if the FTP server requires it for security reasons or you wish
2024        to connect securely whenever remote FTP server supports it.
2025        Default is false since it might trigger certificate verification
2026        errors on misconfigured servers.
2027
2028http.maxRequests::
2029        How many HTTP requests to launch in parallel. Can be overridden
2030        by the `GIT_HTTP_MAX_REQUESTS` environment variable. Default is 5.
2031
2032http.minSessions::
2033        The number of curl sessions (counted across slots) to be kept across
2034        requests. They will not be ended with curl_easy_cleanup() until
2035        http_cleanup() is invoked. If USE_CURL_MULTI is not defined, this
2036        value will be capped at 1. Defaults to 1.
2037
2038http.postBuffer::
2039        Maximum size in bytes of the buffer used by smart HTTP
2040        transports when POSTing data to the remote system.
2041        For requests larger than this buffer size, HTTP/1.1 and
2042        Transfer-Encoding: chunked is used to avoid creating a
2043        massive pack file locally.  Default is 1 MiB, which is
2044        sufficient for most requests.
2045
2046http.lowSpeedLimit, http.lowSpeedTime::
2047        If the HTTP transfer speed is less than 'http.lowSpeedLimit'
2048        for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
2049        Can be overridden by the `GIT_HTTP_LOW_SPEED_LIMIT` and
2050        `GIT_HTTP_LOW_SPEED_TIME` environment variables.
2051
2052http.noEPSV::
2053        A boolean which disables using of EPSV ftp command by curl.
2054        This can helpful with some "poor" ftp servers which don't
2055        support EPSV mode. Can be overridden by the `GIT_CURL_FTP_NO_EPSV`
2056        environment variable. Default is false (curl will use EPSV).
2057
2058http.userAgent::
2059        The HTTP USER_AGENT string presented to an HTTP server.  The default
2060        value represents the version of the client Git such as git/1.7.1.
2061        This option allows you to override this value to a more common value
2062        such as Mozilla/4.0.  This may be necessary, for instance, if
2063        connecting through a firewall that restricts HTTP connections to a set
2064        of common USER_AGENT strings (but not including those like git/1.7.1).
2065        Can be overridden by the `GIT_HTTP_USER_AGENT` environment variable.
2066
2067http.followRedirects::
2068        Whether git should follow HTTP redirects. If set to `true`, git
2069        will transparently follow any redirect issued by a server it
2070        encounters. If set to `false`, git will treat all redirects as
2071        errors. If set to `initial`, git will follow redirects only for
2072        the initial request to a remote, but not for subsequent
2073        follow-up HTTP requests. Since git uses the redirected URL as
2074        the base for the follow-up requests, this is generally
2075        sufficient. The default is `initial`.
2076
2077http.<url>.*::
2078        Any of the http.* options above can be applied selectively to some URLs.
2079        For a config key to match a URL, each element of the config key is
2080        compared to that of the URL, in the following order:
2081+
2082--
2083. Scheme (e.g., `https` in `https://example.com/`). This field
2084  must match exactly between the config key and the URL.
2085
2086. Host/domain name (e.g., `example.com` in `https://example.com/`).
2087  This field must match between the config key and the URL. It is
2088  possible to specify a `*` as part of the host name to match all subdomains
2089  at this level. `https://*.example.com/` for example would match
2090  `https://foo.example.com/`, but not `https://foo.bar.example.com/`.
2091
2092. Port number (e.g., `8080` in `http://example.com:8080/`).
2093  This field must match exactly between the config key and the URL.
2094  Omitted port numbers are automatically converted to the correct
2095  default for the scheme before matching.
2096
2097. Path (e.g., `repo.git` in `https://example.com/repo.git`). The
2098  path field of the config key must match the path field of the URL
2099  either exactly or as a prefix of slash-delimited path elements.  This means
2100  a config key with path `foo/` matches URL path `foo/bar`.  A prefix can only
2101  match on a slash (`/`) boundary.  Longer matches take precedence (so a config
2102  key with path `foo/bar` is a better match to URL path `foo/bar` than a config
2103  key with just path `foo/`).
2104
2105. User name (e.g., `user` in `https://user@example.com/repo.git`). If
2106  the config key has a user name it must match the user name in the
2107  URL exactly. If the config key does not have a user name, that
2108  config key will match a URL with any user name (including none),
2109  but at a lower precedence than a config key with a user name.
2110--
2111+
2112The list above is ordered by decreasing precedence; a URL that matches
2113a config key's path is preferred to one that matches its user name. For example,
2114if the URL is `https://user@example.com/foo/bar` a config key match of
2115`https://example.com/foo` will be preferred over a config key match of
2116`https://user@example.com`.
2117+
2118All URLs are normalized before attempting any matching (the password part,
2119if embedded in the URL, is always ignored for matching purposes) so that
2120equivalent URLs that are simply spelled differently will match properly.
2121Environment variable settings always override any matches.  The URLs that are
2122matched against are those given directly to Git commands.  This means any URLs
2123visited as a result of a redirection do not participate in matching.
2124
2125ssh.variant::
2126        By default, Git determines the command line arguments to use
2127        based on the basename of the configured SSH command (configured
2128        using the environment variable `GIT_SSH` or `GIT_SSH_COMMAND` or
2129        the config setting `core.sshCommand`). If the basename is
2130        unrecognized, Git will attempt to detect support of OpenSSH
2131        options by first invoking the configured SSH command with the
2132        `-G` (print configuration) option and will subsequently use
2133        OpenSSH options (if that is successful) or no options besides
2134        the host and remote command (if it fails).
2135+
2136The config variable `ssh.variant` can be set to override this detection.
2137Valid values are `ssh` (to use OpenSSH options), `plink`, `putty`,
2138`tortoiseplink`, `simple` (no options except the host and remote command).
2139The default auto-detection can be explicitly requested using the value
2140`auto`.  Any other value is treated as `ssh`.  This setting can also be
2141overridden via the environment variable `GIT_SSH_VARIANT`.
2142+
2143The current command-line parameters used for each variant are as
2144follows:
2145+
2146--
2147
2148* `ssh` - [-p port] [-4] [-6] [-o option] [username@]host command
2149
2150* `simple` - [username@]host command
2151
2152* `plink` or `putty` - [-P port] [-4] [-6] [username@]host command
2153
2154* `tortoiseplink` - [-P port] [-4] [-6] -batch [username@]host command
2155
2156--
2157+
2158Except for the `simple` variant, command-line parameters are likely to
2159change as git gains new features.
2160
2161i18n.commitEncoding::
2162        Character encoding the commit messages are stored in; Git itself
2163        does not care per se, but this information is necessary e.g. when
2164        importing commits from emails or in the gitk graphical history
2165        browser (and possibly at other places in the future or in other
2166        porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.
2167
2168i18n.logOutputEncoding::
2169        Character encoding the commit messages are converted to when
2170        running 'git log' and friends.
2171
2172imap::
2173        The configuration variables in the 'imap' section are described
2174        in linkgit:git-imap-send[1].
2175
2176index.threads::
2177        Specifies the number of threads to spawn when loading the index.
2178        This is meant to reduce index load time on multiprocessor machines.
2179        Specifying 0 or 'true' will cause Git to auto-detect the number of
2180        CPU's and set the number of threads accordingly. Specifying 1 or
2181        'false' will disable multithreading. Defaults to 'true'.
2182
2183index.version::
2184        Specify the version with which new index files should be
2185        initialized.  This does not affect existing repositories.
2186
2187init.templateDir::
2188        Specify the directory from which templates will be copied.
2189        (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].)
2190
2191instaweb.browser::
2192        Specify the program that will be used to browse your working
2193        repository in gitweb. See linkgit:git-instaweb[1].
2194
2195instaweb.httpd::
2196        The HTTP daemon command-line to start gitweb on your working
2197        repository. See linkgit:git-instaweb[1].
2198
2199instaweb.local::
2200        If true the web server started by linkgit:git-instaweb[1] will
2201        be bound to the local IP (127.0.0.1).
2202
2203instaweb.modulePath::
2204        The default module path for linkgit:git-instaweb[1] to use
2205        instead of /usr/lib/apache2/modules.  Only used if httpd
2206        is Apache.
2207
2208instaweb.port::
2209        The port number to bind the gitweb httpd to. See
2210        linkgit:git-instaweb[1].
2211
2212interactive.singleKey::
2213        In interactive commands, allow the user to provide one-letter
2214        input with a single key (i.e., without hitting enter).
2215        Currently this is used by the `--patch` mode of
2216        linkgit:git-add[1], linkgit:git-checkout[1], linkgit:git-commit[1],
2217        linkgit:git-reset[1], and linkgit:git-stash[1]. Note that this
2218        setting is silently ignored if portable keystroke input
2219        is not available; requires the Perl module Term::ReadKey.
2220
2221interactive.diffFilter::
2222        When an interactive command (such as `git add --patch`) shows
2223        a colorized diff, git will pipe the diff through the shell
2224        command defined by this configuration variable. The command may
2225        mark up the diff further for human consumption, provided that it
2226        retains a one-to-one correspondence with the lines in the
2227        original diff. Defaults to disabled (no filtering).
2228
2229log.abbrevCommit::
2230        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
2231        linkgit:git-whatchanged[1] assume `--abbrev-commit`. You may
2232        override this option with `--no-abbrev-commit`.
2233
2234log.date::
2235        Set the default date-time mode for the 'log' command.
2236        Setting a value for log.date is similar to using 'git log''s
2237        `--date` option.  See linkgit:git-log[1] for details.
2238
2239log.decorate::
2240        Print out the ref names of any commits that are shown by the log
2241        command. If 'short' is specified, the ref name prefixes 'refs/heads/',
2242        'refs/tags/' and 'refs/remotes/' will not be printed. If 'full' is
2243        specified, the full ref name (including prefix) will be printed.
2244        If 'auto' is specified, then if the output is going to a terminal,
2245        the ref names are shown as if 'short' were given, otherwise no ref
2246        names are shown. This is the same as the `--decorate` option
2247        of the `git log`.
2248
2249log.follow::
2250        If `true`, `git log` will act as if the `--follow` option was used when
2251        a single <path> is given.  This has the same limitations as `--follow`,
2252        i.e. it cannot be used to follow multiple files and does not work well
2253        on non-linear history.
2254
2255log.graphColors::
2256        A list of colors, separated by commas, that can be used to draw
2257        history lines in `git log --graph`.
2258
2259log.showRoot::
2260        If true, the initial commit will be shown as a big creation event.
2261        This is equivalent to a diff against an empty tree.
2262        Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
2263        normally hide the root commit will now show it. True by default.
2264
2265log.showSignature::
2266        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
2267        linkgit:git-whatchanged[1] assume `--show-signature`.
2268
2269log.mailmap::
2270        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
2271        linkgit:git-whatchanged[1] assume `--use-mailmap`.
2272
2273mailinfo.scissors::
2274        If true, makes linkgit:git-mailinfo[1] (and therefore
2275        linkgit:git-am[1]) act by default as if the --scissors option
2276        was provided on the command-line. When active, this features
2277        removes everything from the message body before a scissors
2278        line (i.e. consisting mainly of ">8", "8<" and "-").
2279
2280mailmap.file::
2281        The location of an augmenting mailmap file. The default
2282        mailmap, located in the root of the repository, is loaded
2283        first, then the mailmap file pointed to by this variable.
2284        The location of the mailmap file may be in a repository
2285        subdirectory, or somewhere outside of the repository itself.
2286        See linkgit:git-shortlog[1] and linkgit:git-blame[1].
2287
2288mailmap.blob::
2289        Like `mailmap.file`, but consider the value as a reference to a
2290        blob in the repository. If both `mailmap.file` and
2291        `mailmap.blob` are given, both are parsed, with entries from
2292        `mailmap.file` taking precedence. In a bare repository, this
2293        defaults to `HEAD:.mailmap`. In a non-bare repository, it
2294        defaults to empty.
2295
2296man.viewer::
2297        Specify the programs that may be used to display help in the
2298        'man' format. See linkgit:git-help[1].
2299
2300man.<tool>.cmd::
2301        Specify the command to invoke the specified man viewer. The
2302        specified command is evaluated in shell with the man page
2303        passed as argument. (See linkgit:git-help[1].)
2304
2305man.<tool>.path::
2306        Override the path for the given tool that may be used to
2307        display help in the 'man' format. See linkgit:git-help[1].
2308
2309include::merge-config.txt[]
2310
2311mergetool.<tool>.path::
2312        Override the path for the given tool.  This is useful in case
2313        your tool is not in the PATH.
2314
2315mergetool.<tool>.cmd::
2316        Specify the command to invoke the specified merge tool.  The
2317        specified command is evaluated in shell with the following
2318        variables available: 'BASE' is the name of a temporary file
2319        containing the common base of the files to be merged, if available;
2320        'LOCAL' is the name of a temporary file containing the contents of
2321        the file on the current branch; 'REMOTE' is the name of a temporary
2322        file containing the contents of the file from the branch being
2323        merged; 'MERGED' contains the name of the file to which the merge
2324        tool should write the results of a successful merge.
2325
2326mergetool.<tool>.trustExitCode::
2327        For a custom merge command, specify whether the exit code of
2328        the merge command can be used to determine whether the merge was
2329        successful.  If this is not set to true then the merge target file
2330        timestamp is checked and the merge assumed to have been successful
2331        if the file has been updated, otherwise the user is prompted to
2332        indicate the success of the merge.
2333
2334mergetool.meld.hasOutput::
2335        Older versions of `meld` do not support the `--output` option.
2336        Git will attempt to detect whether `meld` supports `--output`
2337        by inspecting the output of `meld --help`.  Configuring
2338        `mergetool.meld.hasOutput` will make Git skip these checks and
2339        use the configured value instead.  Setting `mergetool.meld.hasOutput`
2340        to `true` tells Git to unconditionally use the `--output` option,
2341        and `false` avoids using `--output`.
2342
2343mergetool.keepBackup::
2344        After performing a merge, the original file with conflict markers
2345        can be saved as a file with a `.orig` extension.  If this variable
2346        is set to `false` then this file is not preserved.  Defaults to
2347        `true` (i.e. keep the backup files).
2348
2349mergetool.keepTemporaries::
2350        When invoking a custom merge tool, Git uses a set of temporary
2351        files to pass to the tool. If the tool returns an error and this
2352        variable is set to `true`, then these temporary files will be
2353        preserved, otherwise they will be removed after the tool has
2354        exited. Defaults to `false`.
2355
2356mergetool.writeToTemp::
2357        Git writes temporary 'BASE', 'LOCAL', and 'REMOTE' versions of
2358        conflicting files in the worktree by default.  Git will attempt
2359        to use a temporary directory for these files when set `true`.
2360        Defaults to `false`.
2361
2362mergetool.prompt::
2363        Prompt before each invocation of the merge resolution program.
2364
2365notes.mergeStrategy::
2366        Which merge strategy to choose by default when resolving notes
2367        conflicts.  Must be one of `manual`, `ours`, `theirs`, `union`, or
2368        `cat_sort_uniq`.  Defaults to `manual`.  See "NOTES MERGE STRATEGIES"
2369        section of linkgit:git-notes[1] for more information on each strategy.
2370
2371notes.<name>.mergeStrategy::
2372        Which merge strategy to choose when doing a notes merge into
2373        refs/notes/<name>.  This overrides the more general
2374        "notes.mergeStrategy".  See the "NOTES MERGE STRATEGIES" section in
2375        linkgit:git-notes[1] for more information on the available strategies.
2376
2377notes.displayRef::
2378        The (fully qualified) refname from which to show notes when
2379        showing commit messages.  The value of this variable can be set
2380        to a glob, in which case notes from all matching refs will be
2381        shown.  You may also specify this configuration variable
2382        several times.  A warning will be issued for refs that do not
2383        exist, but a glob that does not match any refs is silently
2384        ignored.
2385+
2386This setting can be overridden with the `GIT_NOTES_DISPLAY_REF`
2387environment variable, which must be a colon separated list of refs or
2388globs.
2389+
2390The effective value of "core.notesRef" (possibly overridden by
2391GIT_NOTES_REF) is also implicitly added to the list of refs to be
2392displayed.
2393
2394notes.rewrite.<command>::
2395        When rewriting commits with <command> (currently `amend` or
2396        `rebase`) and this variable is set to `true`, Git
2397        automatically copies your notes from the original to the
2398        rewritten commit.  Defaults to `true`, but see
2399        "notes.rewriteRef" below.
2400
2401notes.rewriteMode::
2402        When copying notes during a rewrite (see the
2403        "notes.rewrite.<command>" option), determines what to do if
2404        the target commit already has a note.  Must be one of
2405        `overwrite`, `concatenate`, `cat_sort_uniq`, or `ignore`.
2406        Defaults to `concatenate`.
2407+
2408This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
2409environment variable.
2410
2411notes.rewriteRef::
2412        When copying notes during a rewrite, specifies the (fully
2413        qualified) ref whose notes should be copied.  The ref may be a
2414        glob, in which case notes in all matching refs will be copied.
2415        You may also specify this configuration several times.
2416+
2417Does not have a default value; you must configure this variable to
2418enable note rewriting.  Set it to `refs/notes/commits` to enable
2419rewriting for the default commit notes.
2420+
2421This setting can be overridden with the `GIT_NOTES_REWRITE_REF`
2422environment variable, which must be a colon separated list of refs or
2423globs.
2424
2425pack.window::
2426        The size of the window used by linkgit:git-pack-objects[1] when no
2427        window size is given on the command line. Defaults to 10.
2428
2429pack.depth::
2430        The maximum delta depth used by linkgit:git-pack-objects[1] when no
2431        maximum depth is given on the command line. Defaults to 50.
2432        Maximum value is 4095.
2433
2434pack.windowMemory::
2435        The maximum size of memory that is consumed by each thread
2436        in linkgit:git-pack-objects[1] for pack window memory when
2437        no limit is given on the command line.  The value can be
2438        suffixed with "k", "m", or "g".  When left unconfigured (or
2439        set explicitly to 0), there will be no limit.
2440
2441pack.compression::
2442        An integer -1..9, indicating the compression level for objects
2443        in a pack file. -1 is the zlib default. 0 means no
2444        compression, and 1..9 are various speed/size tradeoffs, 9 being
2445        slowest.  If not set,  defaults to core.compression.  If that is
2446        not set,  defaults to -1, the zlib default, which is "a default
2447        compromise between speed and compression (currently equivalent
2448        to level 6)."
2449+
2450Note that changing the compression level will not automatically recompress
2451all existing objects. You can force recompression by passing the -F option
2452to linkgit:git-repack[1].
2453
2454pack.island::
2455        An extended regular expression configuring a set of delta
2456        islands. See "DELTA ISLANDS" in linkgit:git-pack-objects[1]
2457        for details.
2458
2459pack.islandCore::
2460        Specify an island name which gets to have its objects be
2461        packed first. This creates a kind of pseudo-pack at the front
2462        of one pack, so that the objects from the specified island are
2463        hopefully faster to copy into any pack that should be served
2464        to a user requesting these objects. In practice this means
2465        that the island specified should likely correspond to what is
2466        the most commonly cloned in the repo. See also "DELTA ISLANDS"
2467        in linkgit:git-pack-objects[1].
2468
2469pack.deltaCacheSize::
2470        The maximum memory in bytes used for caching deltas in
2471        linkgit:git-pack-objects[1] before writing them out to a pack.
2472        This cache is used to speed up the writing object phase by not
2473        having to recompute the final delta result once the best match
2474        for all objects is found.  Repacking large repositories on machines
2475        which are tight with memory might be badly impacted by this though,
2476        especially if this cache pushes the system into swapping.
2477        A value of 0 means no limit. The smallest size of 1 byte may be
2478        used to virtually disable this cache. Defaults to 256 MiB.
2479
2480pack.deltaCacheLimit::
2481        The maximum size of a delta, that is cached in
2482        linkgit:git-pack-objects[1]. This cache is used to speed up the
2483        writing object phase by not having to recompute the final delta
2484        result once the best match for all objects is found.
2485        Defaults to 1000. Maximum value is 65535.
2486
2487pack.threads::
2488        Specifies the number of threads to spawn when searching for best
2489        delta matches.  This requires that linkgit:git-pack-objects[1]
2490        be compiled with pthreads otherwise this option is ignored with a
2491        warning. This is meant to reduce packing time on multiprocessor
2492        machines. The required amount of memory for the delta search window
2493        is however multiplied by the number of threads.
2494        Specifying 0 will cause Git to auto-detect the number of CPU's
2495        and set the number of threads accordingly.
2496
2497pack.indexVersion::
2498        Specify the default pack index version.  Valid values are 1 for
2499        legacy pack index used by Git versions prior to 1.5.2, and 2 for
2500        the new pack index with capabilities for packs larger than 4 GB
2501        as well as proper protection against the repacking of corrupted
2502        packs.  Version 2 is the default.  Note that version 2 is enforced
2503        and this config option ignored whenever the corresponding pack is
2504        larger than 2 GB.
2505+
2506If you have an old Git that does not understand the version 2 `*.idx` file,
2507cloning or fetching over a non native protocol (e.g. "http")
2508that will copy both `*.pack` file and corresponding `*.idx` file from the
2509other side may give you a repository that cannot be accessed with your
2510older version of Git. If the `*.pack` file is smaller than 2 GB, however,
2511you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
2512the `*.idx` file.
2513
2514pack.packSizeLimit::
2515        The maximum size of a pack.  This setting only affects
2516        packing to a file when repacking, i.e. the git:// protocol
2517        is unaffected.  It can be overridden by the `--max-pack-size`
2518        option of linkgit:git-repack[1].  Reaching this limit results
2519        in the creation of multiple packfiles; which in turn prevents
2520        bitmaps from being created.
2521        The minimum size allowed is limited to 1 MiB.
2522        The default is unlimited.
2523        Common unit suffixes of 'k', 'm', or 'g' are
2524        supported.
2525
2526pack.useBitmaps::
2527        When true, git will use pack bitmaps (if available) when packing
2528        to stdout (e.g., during the server side of a fetch). Defaults to
2529        true. You should not generally need to turn this off unless
2530        you are debugging pack bitmaps.
2531
2532pack.writeBitmaps (deprecated)::
2533        This is a deprecated synonym for `repack.writeBitmaps`.
2534
2535pack.writeBitmapHashCache::
2536        When true, git will include a "hash cache" section in the bitmap
2537        index (if one is written). This cache can be used to feed git's
2538        delta heuristics, potentially leading to better deltas between
2539        bitmapped and non-bitmapped objects (e.g., when serving a fetch
2540        between an older, bitmapped pack and objects that have been
2541        pushed since the last gc). The downside is that it consumes 4
2542        bytes per object of disk space, and that JGit's bitmap
2543        implementation does not understand it, causing it to complain if
2544        Git and JGit are used on the same repository. Defaults to false.
2545
2546pager.<cmd>::
2547        If the value is boolean, turns on or off pagination of the
2548        output of a particular Git subcommand when writing to a tty.
2549        Otherwise, turns on pagination for the subcommand using the
2550        pager specified by the value of `pager.<cmd>`.  If `--paginate`
2551        or `--no-pager` is specified on the command line, it takes
2552        precedence over this option.  To disable pagination for all
2553        commands, set `core.pager` or `GIT_PAGER` to `cat`.
2554
2555pretty.<name>::
2556        Alias for a --pretty= format string, as specified in
2557        linkgit:git-log[1]. Any aliases defined here can be used just
2558        as the built-in pretty formats could. For example,
2559        running `git config pretty.changelog "format:* %H %s"`
2560        would cause the invocation `git log --pretty=changelog`
2561        to be equivalent to running `git log "--pretty=format:* %H %s"`.
2562        Note that an alias with the same name as a built-in format
2563        will be silently ignored.
2564
2565protocol.allow::
2566        If set, provide a user defined default policy for all protocols which
2567        don't explicitly have a policy (`protocol.<name>.allow`).  By default,
2568        if unset, known-safe protocols (http, https, git, ssh, file) have a
2569        default policy of `always`, known-dangerous protocols (ext) have a
2570        default policy of `never`, and all other protocols have a default
2571        policy of `user`.  Supported policies:
2572+
2573--
2574
2575* `always` - protocol is always able to be used.
2576
2577* `never` - protocol is never able to be used.
2578
2579* `user` - protocol is only able to be used when `GIT_PROTOCOL_FROM_USER` is
2580  either unset or has a value of 1.  This policy should be used when you want a
2581  protocol to be directly usable by the user but don't want it used by commands which
2582  execute clone/fetch/push commands without user input, e.g. recursive
2583  submodule initialization.
2584
2585--
2586
2587protocol.<name>.allow::
2588        Set a policy to be used by protocol `<name>` with clone/fetch/push
2589        commands. See `protocol.allow` above for the available policies.
2590+
2591The protocol names currently used by git are:
2592+
2593--
2594  - `file`: any local file-based path (including `file://` URLs,
2595    or local paths)
2596
2597  - `git`: the anonymous git protocol over a direct TCP
2598    connection (or proxy, if configured)
2599
2600  - `ssh`: git over ssh (including `host:path` syntax,
2601    `ssh://`, etc).
2602
2603  - `http`: git over http, both "smart http" and "dumb http".
2604    Note that this does _not_ include `https`; if you want to configure
2605    both, you must do so individually.
2606
2607  - any external helpers are named by their protocol (e.g., use
2608    `hg` to allow the `git-remote-hg` helper)
2609--
2610
2611protocol.version::
2612        Experimental. If set, clients will attempt to communicate with a
2613        server using the specified protocol version.  If unset, no
2614        attempt will be made by the client to communicate using a
2615        particular protocol version, this results in protocol version 0
2616        being used.
2617        Supported versions:
2618+
2619--
2620
2621* `0` - the original wire protocol.
2622
2623* `1` - the original wire protocol with the addition of a version string
2624  in the initial response from the server.
2625
2626* `2` - link:technical/protocol-v2.html[wire protocol version 2].

2638remote.pushDefault::
2639        The remote to push to by default.  Overrides
2640        `branch.<name>.remote` for all branches, and is overridden by
2641        `branch.<name>.pushRemote` for specific branches.
2642
2643remote.<name>.url::
2644        The URL of a remote repository.  See linkgit:git-fetch[1] or
2645        linkgit:git-push[1].
2646
2647remote.<name>.pushurl::
2648        The push URL of a remote repository.  See linkgit:git-push[1].
2649
2650remote.<name>.proxy::
2651        For remotes that require curl (http, https and ftp), the URL to
2652        the proxy to use for that remote.  Set to the empty string to
2653        disable proxying for that remote.
2654
2655remote.<name>.proxyAuthMethod::
2656        For remotes that require curl (http, https and ftp), the method to use for
2657        authenticating against the proxy in use (probably set in
2658        `remote.<name>.proxy`). See `http.proxyAuthMethod`.
2659
2660remote.<name>.fetch::
2661        The default set of "refspec" for linkgit:git-fetch[1]. See
2662        linkgit:git-fetch[1].
2663
2664remote.<name>.push::
2665        The default set of "refspec" for linkgit:git-push[1]. See
2666        linkgit:git-push[1].
2667
2668remote.<name>.mirror::
2669        If true, pushing to this remote will automatically behave
2670        as if the `--mirror` option was given on the command line.
2671
2672remote.<name>.skipDefaultUpdate::
2673        If true, this remote will be skipped by default when updating
2674        using linkgit:git-fetch[1] or the `update` subcommand of
2675        linkgit:git-remote[1].
2676
2677remote.<name>.skipFetchAll::
2678        If true, this remote will be skipped by default when updating
2679        using linkgit:git-fetch[1] or the `update` subcommand of
2680        linkgit:git-remote[1].
2681
2682remote.<name>.receivepack::
2683        The default program to execute on the remote side when pushing.  See
2684        option --receive-pack of linkgit:git-push[1].
2685
2686remote.<name>.uploadpack::
2687        The default program to execute on the remote side when fetching.  See
2688        option --upload-pack of linkgit:git-fetch-pack[1].
2689
2690remote.<name>.tagOpt::
2691        Setting this value to --no-tags disables automatic tag following when
2692        fetching from remote <name>. Setting it to --tags will fetch every
2693        tag from remote <name>, even if they are not reachable from remote
2694        branch heads. Passing these flags directly to linkgit:git-fetch[1] can
2695        override this setting. See options --tags and --no-tags of
2696        linkgit:git-fetch[1].
2697
2698remote.<name>.vcs::
2699        Setting this to a value <vcs> will cause Git to interact with
2700        the remote with the git-remote-<vcs> helper.
2701
2702remote.<name>.prune::
2703        When set to true, fetching from this remote by default will also
2704        remove any remote-tracking references that no longer exist on the
2705        remote (as if the `--prune` option was given on the command line).
2706        Overrides `fetch.prune` settings, if any.
2707
2708remote.<name>.pruneTags::
2709        When set to true, fetching from this remote by default will also
2710        remove any local tags that no longer exist on the remote if pruning
2711        is activated in general via `remote.<name>.prune`, `fetch.prune` or
2712        `--prune`. Overrides `fetch.pruneTags` settings, if any.
2713+
2714See also `remote.<name>.prune` and the PRUNING section of
2715linkgit:git-fetch[1].
2716
2717remotes.<group>::
2718        The list of remotes which are fetched by "git remote update
2719        <group>".  See linkgit:git-remote[1].
2720
2721repack.useDeltaBaseOffset::
2722        By default, linkgit:git-repack[1] creates packs that use
2723        delta-base offset. If you need to share your repository with
2724        Git older than version 1.4.4, either directly or via a dumb
2725        protocol such as http, then you need to set this option to
2726        "false" and repack. Access from old Git versions over the
2727        native protocol are unaffected by this option.
2728
2729repack.packKeptObjects::
2730        If set to true, makes `git repack` act as if
2731        `--pack-kept-objects` was passed. See linkgit:git-repack[1] for
2732        details. Defaults to `false` normally, but `true` if a bitmap
2733        index is being written (either via `--write-bitmap-index` or
2734        `repack.writeBitmaps`).
2735
2736repack.useDeltaIslands::
2737        If set to true, makes `git repack` act as if `--delta-islands`
2738        was passed. Defaults to `false`.
2739
2740repack.writeBitmaps::
2741        When true, git will write a bitmap index when packing all
2742        objects to disk (e.g., when `git repack -a` is run).  This
2743        index can speed up the "counting objects" phase of subsequent
2744        packs created for clones and fetches, at the cost of some disk
2745        space and extra time spent on the initial repack.  This has
2746        no effect if multiple packfiles are created.
2747        Defaults to false.
2748
2749rerere.autoUpdate::
2750        When set to true, `git-rerere` updates the index with the
2751        resulting contents after it cleanly resolves conflicts using
2752        previously recorded resolution.  Defaults to false.
2753
2754rerere.enabled::
2755        Activate recording of resolved conflicts, so that identical
2756        conflict hunks can be resolved automatically, should they be
2757        encountered again.  By default, linkgit:git-rerere[1] is
2758        enabled if there is an `rr-cache` directory under the
2759        `$GIT_DIR`, e.g. if "rerere" was previously used in the
2760        repository.
2761
2762include::sendemail-config.txt[]
2763
2764sequence.editor::
2765        Text editor used by `git rebase -i` for editing the rebase instruction file.
2766        The value is meant to be interpreted by the shell when it is used.
2767        It can be overridden by the `GIT_SEQUENCE_EDITOR` environment variable.
2768        When not configured the default commit message editor is used instead.
2769
2770showBranch.default::
2771        The default set of branches for linkgit:git-show-branch[1].
2772        See linkgit:git-show-branch[1].
2773
2774splitIndex.maxPercentChange::
2775        When the split index feature is used, this specifies the
2776        percent of entries the split index can contain compared to the
2777        total number of entries in both the split index and the shared
2778        index before a new shared index is written.
2779        The value should be between 0 and 100. If the value is 0 then
2780        a new shared index is always written, if it is 100 a new
2781        shared index is never written.
2782        By default the value is 20, so a new shared index is written
2783        if the number of entries in the split index would be greater
2784        than 20 percent of the total number of entries.
2785        See linkgit:git-update-index[1].
2786
2787splitIndex.sharedIndexExpire::
2788        When the split index feature is used, shared index files that
2789        were not modified since the time this variable specifies will
2790        be removed when a new shared index file is created. The value
2791        "now" expires all entries immediately, and "never" suppresses
2792        expiration altogether.
2793        The default value is "2.weeks.ago".
2794        Note that a shared index file is considered modified (for the
2795        purpose of expiration) each time a new split-index file is
2796        either created based on it or read from it.
2797        See linkgit:git-update-index[1].
2798
2799status.relativePaths::
2800        By default, linkgit:git-status[1] shows paths relative to the
2801        current directory. Setting this variable to `false` shows paths
2802        relative to the repository root (this was the default for Git
2803        prior to v1.5.4).
2804
2805status.short::
2806        Set to true to enable --short by default in linkgit:git-status[1].
2807        The option --no-short takes precedence over this variable.
2808
2809status.branch::
2810        Set to true to enable --branch by default in linkgit:git-status[1].
2811        The option --no-branch takes precedence over this variable.
2812
2813status.displayCommentPrefix::
2814        If set to true, linkgit:git-status[1] will insert a comment
2815        prefix before each output line (starting with
2816        `core.commentChar`, i.e. `#` by default). This was the
2817        behavior of linkgit:git-status[1] in Git 1.8.4 and previous.
2818        Defaults to false.
2819
2820status.renameLimit::
2821        The number of files to consider when performing rename detection
2822        in linkgit:git-status[1] and linkgit:git-commit[1]. Defaults to
2823        the value of diff.renameLimit.
2824
2825status.renames::
2826        Whether and how Git detects renames in linkgit:git-status[1] and
2827        linkgit:git-commit[1] .  If set to "false", rename detection is
2828        disabled. If set to "true", basic rename detection is enabled.
2829        If set to "copies" or "copy", Git will detect copies, as well.
2830        Defaults to the value of diff.renames.
2831
2832status.showStash::
2833        If set to true, linkgit:git-status[1] will display the number of
2834        entries currently stashed away.
2835        Defaults to false.
2836
2837status.showUntrackedFiles::
2838        By default, linkgit:git-status[1] and linkgit:git-commit[1] show
2839        files which are not currently tracked by Git. Directories which
2840        contain only untracked files, are shown with the directory name
2841        only. Showing untracked files means that Git needs to lstat() all
2842        the files in the whole repository, which might be slow on some
2843        systems. So, this variable controls how the commands displays
2844        the untracked files. Possible values are:
2845+
2846--
2847* `no` - Show no untracked files.
2848* `normal` - Show untracked files and directories.
2849* `all` - Show also individual files in untracked directories.
2850--
2851+
2852If this variable is not specified, it defaults to 'normal'.
2853This variable can be overridden with the -u|--untracked-files option
2854of linkgit:git-status[1] and linkgit:git-commit[1].
2855
2856status.submoduleSummary::
2857        Defaults to false.
2858        If this is set to a non zero number or true (identical to -1 or an
2859        unlimited number), the submodule summary will be enabled and a
2860        summary of commits for modified submodules will be shown (see
2861        --summary-limit option of linkgit:git-submodule[1]). Please note
2862        that the summary output command will be suppressed for all
2863        submodules when `diff.ignoreSubmodules` is set to 'all' or only
2864        for those submodules where `submodule.<name>.ignore=all`. The only
2865        exception to that rule is that status and commit will show staged
2866        submodule changes. To
2867        also view the summary for ignored submodules you can either use
2868        the --ignore-submodules=dirty command-line option or the 'git
2869        submodule summary' command, which shows a similar output but does
2870        not honor these settings.
2871
2872stash.showPatch::
2873        If this is set to true, the `git stash show` command without an
2874        option will show the stash entry in patch form.  Defaults to false.
2875        See description of 'show' command in linkgit:git-stash[1].
2876
2877stash.showStat::
2878        If this is set to true, the `git stash show` command without an
2879        option will show diffstat of the stash entry.  Defaults to true.
2880        See description of 'show' command in linkgit:git-stash[1].
2881
2882include::submodule-config.txt[]
2883
2884tag.forceSignAnnotated::
2885        A boolean to specify whether annotated tags created should be GPG signed.
2886        If `--annotate` is specified on the command line, it takes
2887        precedence over this option.
2888
2889tag.sort::
2890        This variable controls the sort ordering of tags when displayed by
2891        linkgit:git-tag[1]. Without the "--sort=<value>" option provided, the
2892        value of this variable will be used as the default.
2893
2894tar.umask::
2895        This variable can be used to restrict the permission bits of
2896        tar archive entries.  The default is 0002, which turns off the
2897        world write bit.  The special value "user" indicates that the
2898        archiving user's umask will be used instead.  See umask(2) and
2899        linkgit:git-archive[1].
2900
2901transfer.fsckObjects::
2902        When `fetch.fsckObjects` or `receive.fsckObjects` are
2903        not set, the value of this variable is used instead.
2904        Defaults to false.
2905+
2906When set, the fetch or receive will abort in the case of a malformed
2907object or a link to a nonexistent object. In addition, various other
2908issues are checked for, including legacy issues (see `fsck.<msg-id>`),
2909and potential security issues like the existence of a `.GIT` directory
2910or a malicious `.gitmodules` file (see the release notes for v2.2.1
2911and v2.17.1 for details). Other sanity and security checks may be
2912added in future releases.
2913+
2914On the receiving side, failing fsckObjects will make those objects
2915unreachable, see "QUARANTINE ENVIRONMENT" in
2916linkgit:git-receive-pack[1]. On the fetch side, malformed objects will
2917instead be left unreferenced in the repository.
2918+
2919Due to the non-quarantine nature of the `fetch.fsckObjects`
2920implementation it can not be relied upon to leave the object store
2921clean like `receive.fsckObjects` can.
2922+
2923As objects are unpacked they're written to the object store, so there
2924can be cases where malicious objects get introduced even though the
2925"fetch" failed, only to have a subsequent "fetch" succeed because only
2926new incoming objects are checked, not those that have already been
2927written to the object store. That difference in behavior should not be
2928relied upon. In the future, such objects may be quarantined for
2929"fetch" as well.
2930+
2931For now, the paranoid need to find some way to emulate the quarantine
2932environment if they'd like the same protection as "push". E.g. in the
2933case of an internal mirror do the mirroring in two steps, one to fetch
2934the untrusted objects, and then do a second "push" (which will use the
2935quarantine) to another internal repo, and have internal clients
2936consume this pushed-to repository, or embargo internal fetches and
2937only allow them once a full "fsck" has run (and no new fetches have
2938happened in the meantime).
2939
2940transfer.hideRefs::
2941        String(s) `receive-pack` and `upload-pack` use to decide which
2942        refs to omit from their initial advertisements.  Use more than
2943        one definition to specify multiple prefix strings. A ref that is
2944        under the hierarchies listed in the value of this variable is
2945        excluded, and is hidden when responding to `git push` or `git
2946        fetch`.  See `receive.hideRefs` and `uploadpack.hideRefs` for
2947        program-specific versions of this config.
2948+
2949You may also include a `!` in front of the ref name to negate the entry,
2950explicitly exposing it, even if an earlier entry marked it as hidden.
2951If you have multiple hideRefs values, later entries override earlier ones
2952(and entries in more-specific config files override less-specific ones).
2953+
2954If a namespace is in use, the namespace prefix is stripped from each
2955reference before it is matched against `transfer.hiderefs` patterns.
2956For example, if `refs/heads/master` is specified in `transfer.hideRefs` and
2957the current namespace is `foo`, then `refs/namespaces/foo/refs/heads/master`
2958is omitted from the advertisements but `refs/heads/master` and
2959`refs/namespaces/bar/refs/heads/master` are still advertised as so-called
2960"have" lines. In order to match refs before stripping, add a `^` in front of
2961the ref name. If you combine `!` and `^`, `!` must be specified first.
2962+
2963Even if you hide refs, a client may still be able to steal the target
2964objects via the techniques described in the "SECURITY" section of the
2965linkgit:gitnamespaces[7] man page; it's best to keep private data in a
2966separate repository.
2967
2968transfer.unpackLimit::
2969        When `fetch.unpackLimit` or `receive.unpackLimit` are
2970        not set, the value of this variable is used instead.
2971        The default value is 100.
2972
2973uploadarchive.allowUnreachable::
2974        If true, allow clients to use `git archive --remote` to request
2975        any tree, whether reachable from the ref tips or not. See the
2976        discussion in the "SECURITY" section of
2977        linkgit:git-upload-archive[1] for more details. Defaults to
2978        `false`.
2979
2980uploadpack.hideRefs::
2981        This variable is the same as `transfer.hideRefs`, but applies
2982        only to `upload-pack` (and so affects only fetches, not pushes).
2983        An attempt to fetch a hidden ref by `git fetch` will fail.  See
2984        also `uploadpack.allowTipSHA1InWant`.
2985
2986uploadpack.allowTipSHA1InWant::
2987        When `uploadpack.hideRefs` is in effect, allow `upload-pack`
2988        to accept a fetch request that asks for an object at the tip
2989        of a hidden ref (by default, such a request is rejected).
2990        See also `uploadpack.hideRefs`.  Even if this is false, a client
2991        may be able to steal objects via the techniques described in the
2992        "SECURITY" section of the linkgit:gitnamespaces[7] man page; it's
2993        best to keep private data in a separate repository.
2994
2995uploadpack.allowReachableSHA1InWant::
2996        Allow `upload-pack` to accept a fetch request that asks for an
2997        object that is reachable from any ref tip. However, note that
2998        calculating object reachability is computationally expensive.
2999        Defaults to `false`.  Even if this is false, a client may be able
3000        to steal objects via the techniques described in the "SECURITY"
3001        section of the linkgit:gitnamespaces[7] man page; it's best to
3002        keep private data in a separate repository.
3003
3004uploadpack.allowAnySHA1InWant::
3005        Allow `upload-pack` to accept a fetch request that asks for any
3006        object at all.
3007        Defaults to `false`.
3008
3009uploadpack.keepAlive::
3010        When `upload-pack` has started `pack-objects`, there may be a
3011        quiet period while `pack-objects` prepares the pack. Normally
3012        it would output progress information, but if `--quiet` was used
3013        for the fetch, `pack-objects` will output nothing at all until
3014        the pack data begins. Some clients and networks may consider
3015        the server to be hung and give up. Setting this option instructs
3016        `upload-pack` to send an empty keepalive packet every
3017        `uploadpack.keepAlive` seconds. Setting this option to 0
3018        disables keepalive packets entirely. The default is 5 seconds.
3019
3020uploadpack.packObjectsHook::
3021        If this option is set, when `upload-pack` would run
3022        `git pack-objects` to create a packfile for a client, it will
3023        run this shell command instead.  The `pack-objects` command and
3024        arguments it _would_ have run (including the `git pack-objects`
3025        at the beginning) are appended to the shell command. The stdin
3026        and stdout of the hook are treated as if `pack-objects` itself
3027        was run. I.e., `upload-pack` will feed input intended for
3028        `pack-objects` to the hook, and expects a completed packfile on
3029        stdout.
3030+
3031Note that this configuration variable is ignored if it is seen in the
3032repository-level config (this is a safety measure against fetching from
3033untrusted repositories).
3034
3035uploadpack.allowFilter::
3036        If this option is set, `upload-pack` will support partial
3037        clone and partial fetch object filtering.
3038
3039uploadpack.allowRefInWant::
3040        If this option is set, `upload-pack` will support the `ref-in-want`
3041        feature of the protocol version 2 `fetch` command.  This feature
3042        is intended for the benefit of load-balanced servers which may
3043        not have the same view of what OIDs their refs point to due to
3044        replication delay.
3045
3046url.<base>.insteadOf::
3047        Any URL that starts with this value will be rewritten to
3048        start, instead, with <base>. In cases where some site serves a
3049        large number of repositories, and serves them with multiple
3050        access methods, and some users need to use different access
3051        methods, this feature allows people to specify any of the
3052        equivalent URLs and have Git automatically rewrite the URL to
3053        the best alternative for the particular user, even for a
3054        never-before-seen repository on the site.  When more than one
3055        insteadOf strings match a given URL, the longest match is used.
3056+
3057Note that any protocol restrictions will be applied to the rewritten
3058URL. If the rewrite changes the URL to use a custom protocol or remote
3059helper, you may need to adjust the `protocol.*.allow` config to permit
3060the request.  In particular, protocols you expect to use for submodules
3061must be set to `always` rather than the default of `user`. See the
3062description of `protocol.allow` above.
3063
3064url.<base>.pushInsteadOf::
3065        Any URL that starts with this value will not be pushed to;
3066        instead, it will be rewritten to start with <base>, and the
3067        resulting URL will be pushed to. In cases where some site serves
3068        a large number of repositories, and serves them with multiple
3069        access methods, some of which do not allow push, this feature
3070        allows people to specify a pull-only URL and have Git
3071        automatically use an appropriate URL to push, even for a
3072        never-before-seen repository on the site.  When more than one
3073        pushInsteadOf strings match a given URL, the longest match is
3074        used.  If a remote has an explicit pushurl, Git will ignore this
3075        setting for that remote.
3076
3077user.email::
3078        Your email address to be recorded in any newly created commits.
3079        Can be overridden by the `GIT_AUTHOR_EMAIL`, `GIT_COMMITTER_EMAIL`, and
3080        `EMAIL` environment variables.  See linkgit:git-commit-tree[1].
3081
3082user.name::
3083        Your full name to be recorded in any newly created commits.
3084        Can be overridden by the `GIT_AUTHOR_NAME` and `GIT_COMMITTER_NAME`
3085        environment variables.  See linkgit:git-commit-tree[1].
3086
3087user.useConfigOnly::
3088        Instruct Git to avoid trying to guess defaults for `user.email`
3089        and `user.name`, and instead retrieve the values only from the
3090        configuration. For example, if you have multiple email addresses
3091        and would like to use a different one for each repository, then
3092        with this configuration option set to `true` in the global config
3093        along with a name, Git will prompt you to set up an email before
3094        making new commits in a newly cloned repository.
3095        Defaults to `false`.
3096
3097user.signingKey::
3098        If linkgit:git-tag[1] or linkgit:git-commit[1] is not selecting the
3099        key you want it to automatically when creating a signed tag or
3100        commit, you can override the default selection with this variable.
3101        This option is passed unchanged to gpg's --local-user parameter,
3102        so you may specify a key using any method that gpg supports.
3103
3104versionsort.prereleaseSuffix (deprecated)::
3105        Deprecated alias for `versionsort.suffix`.  Ignored if
3106        `versionsort.suffix` is set.
3107
3108versionsort.suffix::
3109        Even when version sort is used in linkgit:git-tag[1], tagnames
3110        with the same base version but different suffixes are still sorted
3111        lexicographically, resulting e.g. in prerelease tags appearing
3112        after the main release (e.g. "1.0-rc1" after "1.0").  This
3113        variable can be specified to determine the sorting order of tags
3114        with different suffixes.
3115+
3116By specifying a single suffix in this variable, any tagname containing
3117that suffix will appear before the corresponding main release.  E.g. if
3118the variable is set to "-rc", then all "1.0-rcX" tags will appear before
3119"1.0".  If specified multiple times, once per suffix, then the order of
3120suffixes in the configuration will determine the sorting order of tagnames
3121with those suffixes.  E.g. if "-pre" appears before "-rc" in the
3122configuration, then all "1.0-preX" tags will be listed before any
3123"1.0-rcX" tags.  The placement of the main release tag relative to tags
3124with various suffixes can be determined by specifying the empty suffix
3125among those other suffixes.  E.g. if the suffixes "-rc", "", "-ck" and
3126"-bfs" appear in the configuration in this order, then all "v4.8-rcX" tags
3127are listed first, followed by "v4.8", then "v4.8-ckX" and finally
3128"v4.8-bfsX".
3129+
3130If more than one suffixes match the same tagname, then that tagname will
3131be sorted according to the suffix which starts at the earliest position in
3132the tagname.  If more than one different matching suffixes start at
3133that earliest position, then that tagname will be sorted according to the
3134longest of those suffixes.
3135The sorting order between different suffixes is undefined if they are
3136in multiple config files.
3137
3138web.browser::
3139        Specify a web browser that may be used by some commands.
3140        Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
3141        may use it.
3142
3143worktree.guessRemote::
3144        With `add`, if no branch argument, and neither of `-b` nor
3145        `-B` nor `--detach` are given, the command defaults to
3146        creating a new branch from HEAD.  If `worktree.guessRemote` is
3147        set to true, `worktree add` tries to find a remote-tracking
3148        branch whose name uniquely matches the new branch name.  If
3149        such a branch exists, it is checked out and set as "upstream"
3150        for the new branch.  If no such match can be found, it falls
3151        back to creating a new branch from the current HEAD.
