   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.

 400repack.useDeltaBaseOffset::
 401        By default, linkgit:git-repack[1] creates packs that use
 402        delta-base offset. If you need to share your repository with
 403        Git older than version 1.4.4, either directly or via a dumb
 404        protocol such as http, then you need to set this option to
 405        "false" and repack. Access from old Git versions over the
 406        native protocol are unaffected by this option.
 407
 408repack.packKeptObjects::
 409        If set to true, makes `git repack` act as if
 410        `--pack-kept-objects` was passed. See linkgit:git-repack[1] for
 411        details. Defaults to `false` normally, but `true` if a bitmap
 412        index is being written (either via `--write-bitmap-index` or
 413        `repack.writeBitmaps`).
 414
 415repack.useDeltaIslands::
 416        If set to true, makes `git repack` act as if `--delta-islands`
 417        was passed. Defaults to `false`.
 418
 419repack.writeBitmaps::
 420        When true, git will write a bitmap index when packing all
 421        objects to disk (e.g., when `git repack -a` is run).  This
 422        index can speed up the "counting objects" phase of subsequent
 423        packs created for clones and fetches, at the cost of some disk
 424        space and extra time spent on the initial repack.  This has
 425        no effect if multiple packfiles are created.
 426        Defaults to false.
 427
 428rerere.autoUpdate::
 429        When set to true, `git-rerere` updates the index with the
 430        resulting contents after it cleanly resolves conflicts using
 431        previously recorded resolution.  Defaults to false.
 432
 433rerere.enabled::
 434        Activate recording of resolved conflicts, so that identical
 435        conflict hunks can be resolved automatically, should they be
 436        encountered again.  By default, linkgit:git-rerere[1] is
 437        enabled if there is an `rr-cache` directory under the
 438        `$GIT_DIR`, e.g. if "rerere" was previously used in the
 439        repository.
 440
 441reset.quiet::
 442        When set to true, 'git reset' will default to the '--quiet' option.
 443
 444include::sendemail-config.txt[]
 445
 446sequence.editor::
 447        Text editor used by `git rebase -i` for editing the rebase instruction file.
 448        The value is meant to be interpreted by the shell when it is used.
 449        It can be overridden by the `GIT_SEQUENCE_EDITOR` environment variable.
 450        When not configured the default commit message editor is used instead.
 451
 452showBranch.default::
 453        The default set of branches for linkgit:git-show-branch[1].
 454        See linkgit:git-show-branch[1].
 455
 456splitIndex.maxPercentChange::
 457        When the split index feature is used, this specifies the
 458        percent of entries the split index can contain compared to the
 459        total number of entries in both the split index and the shared
 460        index before a new shared index is written.
 461        The value should be between 0 and 100. If the value is 0 then
 462        a new shared index is always written, if it is 100 a new
 463        shared index is never written.
 464        By default the value is 20, so a new shared index is written
 465        if the number of entries in the split index would be greater
 466        than 20 percent of the total number of entries.
 467        See linkgit:git-update-index[1].
 468
 469splitIndex.sharedIndexExpire::
 470        When the split index feature is used, shared index files that
 471        were not modified since the time this variable specifies will
 472        be removed when a new shared index file is created. The value
 473        "now" expires all entries immediately, and "never" suppresses
 474        expiration altogether.
 475        The default value is "2.weeks.ago".
 476        Note that a shared index file is considered modified (for the
 477        purpose of expiration) each time a new split-index file is
 478        either created based on it or read from it.
 479        See linkgit:git-update-index[1].
 480
 481include::config/ssh.txt[]
 482
 483status.relativePaths::
 484        By default, linkgit:git-status[1] shows paths relative to the
 485        current directory. Setting this variable to `false` shows paths
 486        relative to the repository root (this was the default for Git
 487        prior to v1.5.4).
 488
 489status.short::
 490        Set to true to enable --short by default in linkgit:git-status[1].
 491        The option --no-short takes precedence over this variable.
 492
 493status.branch::
 494        Set to true to enable --branch by default in linkgit:git-status[1].
 495        The option --no-branch takes precedence over this variable.
 496
 497status.displayCommentPrefix::
 498        If set to true, linkgit:git-status[1] will insert a comment
 499        prefix before each output line (starting with
 500        `core.commentChar`, i.e. `#` by default). This was the
 501        behavior of linkgit:git-status[1] in Git 1.8.4 and previous.
 502        Defaults to false.
 503
 504status.renameLimit::
 505        The number of files to consider when performing rename detection
 506        in linkgit:git-status[1] and linkgit:git-commit[1]. Defaults to
 507        the value of diff.renameLimit.
 508
 509status.renames::
 510        Whether and how Git detects renames in linkgit:git-status[1] and
 511        linkgit:git-commit[1] .  If set to "false", rename detection is
 512        disabled. If set to "true", basic rename detection is enabled.
 513        If set to "copies" or "copy", Git will detect copies, as well.
 514        Defaults to the value of diff.renames.
 515
 516status.showStash::
 517        If set to true, linkgit:git-status[1] will display the number of
 518        entries currently stashed away.
 519        Defaults to false.
 520
 521status.showUntrackedFiles::
 522        By default, linkgit:git-status[1] and linkgit:git-commit[1] show
 523        files which are not currently tracked by Git. Directories which
 524        contain only untracked files, are shown with the directory name
 525        only. Showing untracked files means that Git needs to lstat() all
 526        the files in the whole repository, which might be slow on some
 527        systems. So, this variable controls how the commands displays
 528        the untracked files. Possible values are:
 529+
 530--
 531* `no` - Show no untracked files.
 532* `normal` - Show untracked files and directories.
 533* `all` - Show also individual files in untracked directories.
 534--
 535+
 536If this variable is not specified, it defaults to 'normal'.
 537This variable can be overridden with the -u|--untracked-files option
 538of linkgit:git-status[1] and linkgit:git-commit[1].
 539
 540status.submoduleSummary::
 541        Defaults to false.
 542        If this is set to a non zero number or true (identical to -1 or an
 543        unlimited number), the submodule summary will be enabled and a
 544        summary of commits for modified submodules will be shown (see
 545        --summary-limit option of linkgit:git-submodule[1]). Please note
 546        that the summary output command will be suppressed for all
 547        submodules when `diff.ignoreSubmodules` is set to 'all' or only
 548        for those submodules where `submodule.<name>.ignore=all`. The only
 549        exception to that rule is that status and commit will show staged
 550        submodule changes. To
 551        also view the summary for ignored submodules you can either use
 552        the --ignore-submodules=dirty command-line option or the 'git
 553        submodule summary' command, which shows a similar output but does
 554        not honor these settings.
 555
 556stash.showPatch::
 557        If this is set to true, the `git stash show` command without an
 558        option will show the stash entry in patch form.  Defaults to false.
 559        See description of 'show' command in linkgit:git-stash[1].
 560
 561stash.showStat::
 562        If this is set to true, the `git stash show` command without an
 563        option will show diffstat of the stash entry.  Defaults to true.
 564        See description of 'show' command in linkgit:git-stash[1].
 565
 566include::submodule-config.txt[]
 567
 568tag.forceSignAnnotated::
 569        A boolean to specify whether annotated tags created should be GPG signed.
 570        If `--annotate` is specified on the command line, it takes
 571        precedence over this option.
 572
 573tag.sort::
 574        This variable controls the sort ordering of tags when displayed by
 575        linkgit:git-tag[1]. Without the "--sort=<value>" option provided, the
 576        value of this variable will be used as the default.
 577
 578tar.umask::
 579        This variable can be used to restrict the permission bits of
 580        tar archive entries.  The default is 0002, which turns off the
 581        world write bit.  The special value "user" indicates that the
 582        archiving user's umask will be used instead.  See umask(2) and
 583        linkgit:git-archive[1].
 584
 585transfer.fsckObjects::
 586        When `fetch.fsckObjects` or `receive.fsckObjects` are
 587        not set, the value of this variable is used instead.
 588        Defaults to false.
 589+
 590When set, the fetch or receive will abort in the case of a malformed
 591object or a link to a nonexistent object. In addition, various other
 592issues are checked for, including legacy issues (see `fsck.<msg-id>`),
 593and potential security issues like the existence of a `.GIT` directory
 594or a malicious `.gitmodules` file (see the release notes for v2.2.1
 595and v2.17.1 for details). Other sanity and security checks may be
 596added in future releases.
 597+
 598On the receiving side, failing fsckObjects will make those objects
 599unreachable, see "QUARANTINE ENVIRONMENT" in
 600linkgit:git-receive-pack[1]. On the fetch side, malformed objects will
 601instead be left unreferenced in the repository.
 602+
 603Due to the non-quarantine nature of the `fetch.fsckObjects`
 604implementation it can not be relied upon to leave the object store
 605clean like `receive.fsckObjects` can.
 606+
 607As objects are unpacked they're written to the object store, so there
 608can be cases where malicious objects get introduced even though the
 609"fetch" failed, only to have a subsequent "fetch" succeed because only
 610new incoming objects are checked, not those that have already been
 611written to the object store. That difference in behavior should not be
 612relied upon. In the future, such objects may be quarantined for
 613"fetch" as well.
 614+
 615For now, the paranoid need to find some way to emulate the quarantine
 616environment if they'd like the same protection as "push". E.g. in the
 617case of an internal mirror do the mirroring in two steps, one to fetch
 618the untrusted objects, and then do a second "push" (which will use the
 619quarantine) to another internal repo, and have internal clients
 620consume this pushed-to repository, or embargo internal fetches and
 621only allow them once a full "fsck" has run (and no new fetches have
 622happened in the meantime).
 623
 624transfer.hideRefs::
 625        String(s) `receive-pack` and `upload-pack` use to decide which
 626        refs to omit from their initial advertisements.  Use more than
 627        one definition to specify multiple prefix strings. A ref that is
 628        under the hierarchies listed in the value of this variable is
 629        excluded, and is hidden when responding to `git push` or `git
 630        fetch`.  See `receive.hideRefs` and `uploadpack.hideRefs` for
 631        program-specific versions of this config.
 632+
 633You may also include a `!` in front of the ref name to negate the entry,
 634explicitly exposing it, even if an earlier entry marked it as hidden.
 635If you have multiple hideRefs values, later entries override earlier ones
 636(and entries in more-specific config files override less-specific ones).
 637+
 638If a namespace is in use, the namespace prefix is stripped from each
 639reference before it is matched against `transfer.hiderefs` patterns.
 640For example, if `refs/heads/master` is specified in `transfer.hideRefs` and
 641the current namespace is `foo`, then `refs/namespaces/foo/refs/heads/master`
 642is omitted from the advertisements but `refs/heads/master` and
 643`refs/namespaces/bar/refs/heads/master` are still advertised as so-called
 644"have" lines. In order to match refs before stripping, add a `^` in front of
 645the ref name. If you combine `!` and `^`, `!` must be specified first.
 646+
 647Even if you hide refs, a client may still be able to steal the target
 648objects via the techniques described in the "SECURITY" section of the
 649linkgit:gitnamespaces[7] man page; it's best to keep private data in a
 650separate repository.
 651
 652transfer.unpackLimit::
 653        When `fetch.unpackLimit` or `receive.unpackLimit` are
 654        not set, the value of this variable is used instead.
 655        The default value is 100.
 656
 657uploadarchive.allowUnreachable::
 658        If true, allow clients to use `git archive --remote` to request
 659        any tree, whether reachable from the ref tips or not. See the
 660        discussion in the "SECURITY" section of
 661        linkgit:git-upload-archive[1] for more details. Defaults to
 662        `false`.
 663
 664uploadpack.hideRefs::
 665        This variable is the same as `transfer.hideRefs`, but applies
 666        only to `upload-pack` (and so affects only fetches, not pushes).
 667        An attempt to fetch a hidden ref by `git fetch` will fail.  See
 668        also `uploadpack.allowTipSHA1InWant`.
 669
 670uploadpack.allowTipSHA1InWant::
 671        When `uploadpack.hideRefs` is in effect, allow `upload-pack`
 672        to accept a fetch request that asks for an object at the tip
 673        of a hidden ref (by default, such a request is rejected).
 674        See also `uploadpack.hideRefs`.  Even if this is false, a client
 675        may be able to steal objects via the techniques described in the
 676        "SECURITY" section of the linkgit:gitnamespaces[7] man page; it's
 677        best to keep private data in a separate repository.
 678
 679uploadpack.allowReachableSHA1InWant::
 680        Allow `upload-pack` to accept a fetch request that asks for an
 681        object that is reachable from any ref tip. However, note that
 682        calculating object reachability is computationally expensive.
 683        Defaults to `false`.  Even if this is false, a client may be able
 684        to steal objects via the techniques described in the "SECURITY"
 685        section of the linkgit:gitnamespaces[7] man page; it's best to
 686        keep private data in a separate repository.
 687
 688uploadpack.allowAnySHA1InWant::
 689        Allow `upload-pack` to accept a fetch request that asks for any
 690        object at all.
 691        Defaults to `false`.
 692
 693uploadpack.keepAlive::
 694        When `upload-pack` has started `pack-objects`, there may be a
 695        quiet period while `pack-objects` prepares the pack. Normally
 696        it would output progress information, but if `--quiet` was used
 697        for the fetch, `pack-objects` will output nothing at all until
 698        the pack data begins. Some clients and networks may consider
 699        the server to be hung and give up. Setting this option instructs
 700        `upload-pack` to send an empty keepalive packet every
 701        `uploadpack.keepAlive` seconds. Setting this option to 0
 702        disables keepalive packets entirely. The default is 5 seconds.
 703
 704uploadpack.packObjectsHook::
 705        If this option is set, when `upload-pack` would run
 706        `git pack-objects` to create a packfile for a client, it will
 707        run this shell command instead.  The `pack-objects` command and
 708        arguments it _would_ have run (including the `git pack-objects`
 709        at the beginning) are appended to the shell command. The stdin
 710        and stdout of the hook are treated as if `pack-objects` itself
 711        was run. I.e., `upload-pack` will feed input intended for
 712        `pack-objects` to the hook, and expects a completed packfile on
 713        stdout.
 714+
 715Note that this configuration variable is ignored if it is seen in the
 716repository-level config (this is a safety measure against fetching from
 717untrusted repositories).
 718
 719uploadpack.allowFilter::
 720        If this option is set, `upload-pack` will support partial
 721        clone and partial fetch object filtering.
 722
 723uploadpack.allowRefInWant::
 724        If this option is set, `upload-pack` will support the `ref-in-want`
 725        feature of the protocol version 2 `fetch` command.  This feature
 726        is intended for the benefit of load-balanced servers which may
 727        not have the same view of what OIDs their refs point to due to
 728        replication delay.
 729
 730url.<base>.insteadOf::
 731        Any URL that starts with this value will be rewritten to
 732        start, instead, with <base>. In cases where some site serves a
 733        large number of repositories, and serves them with multiple
 734        access methods, and some users need to use different access
 735        methods, this feature allows people to specify any of the
 736        equivalent URLs and have Git automatically rewrite the URL to
 737        the best alternative for the particular user, even for a
 738        never-before-seen repository on the site.  When more than one
 739        insteadOf strings match a given URL, the longest match is used.
 740+
 741Note that any protocol restrictions will be applied to the rewritten
 742URL. If the rewrite changes the URL to use a custom protocol or remote
 743helper, you may need to adjust the `protocol.*.allow` config to permit
 744the request.  In particular, protocols you expect to use for submodules
 745must be set to `always` rather than the default of `user`. See the
 746description of `protocol.allow` above.
 747
 748url.<base>.pushInsteadOf::
 749        Any URL that starts with this value will not be pushed to;
 750        instead, it will be rewritten to start with <base>, and the
 751        resulting URL will be pushed to. In cases where some site serves
 752        a large number of repositories, and serves them with multiple
 753        access methods, some of which do not allow push, this feature
 754        allows people to specify a pull-only URL and have Git
 755        automatically use an appropriate URL to push, even for a
 756        never-before-seen repository on the site.  When more than one
 757        pushInsteadOf strings match a given URL, the longest match is
 758        used.  If a remote has an explicit pushurl, Git will ignore this
 759        setting for that remote.
 760
 761user.email::
 762        Your email address to be recorded in any newly created commits.
 763        Can be overridden by the `GIT_AUTHOR_EMAIL`, `GIT_COMMITTER_EMAIL`, and
 764        `EMAIL` environment variables.  See linkgit:git-commit-tree[1].
 765
 766user.name::
 767        Your full name to be recorded in any newly created commits.
 768        Can be overridden by the `GIT_AUTHOR_NAME` and `GIT_COMMITTER_NAME`
 769        environment variables.  See linkgit:git-commit-tree[1].
 770
 771user.useConfigOnly::
 772        Instruct Git to avoid trying to guess defaults for `user.email`
 773        and `user.name`, and instead retrieve the values only from the
 774        configuration. For example, if you have multiple email addresses
 775        and would like to use a different one for each repository, then
 776        with this configuration option set to `true` in the global config
 777        along with a name, Git will prompt you to set up an email before
 778        making new commits in a newly cloned repository.
 779        Defaults to `false`.
 780
 781user.signingKey::
 782        If linkgit:git-tag[1] or linkgit:git-commit[1] is not selecting the
 783        key you want it to automatically when creating a signed tag or
 784        commit, you can override the default selection with this variable.
 785        This option is passed unchanged to gpg's --local-user parameter,
 786        so you may specify a key using any method that gpg supports.
 787
 788versionsort.prereleaseSuffix (deprecated)::
 789        Deprecated alias for `versionsort.suffix`.  Ignored if
 790        `versionsort.suffix` is set.
 791
 792versionsort.suffix::
 793        Even when version sort is used in linkgit:git-tag[1], tagnames
 794        with the same base version but different suffixes are still sorted
 795        lexicographically, resulting e.g. in prerelease tags appearing
 796        after the main release (e.g. "1.0-rc1" after "1.0").  This
 797        variable can be specified to determine the sorting order of tags
 798        with different suffixes.
 799+
 800By specifying a single suffix in this variable, any tagname containing
 801that suffix will appear before the corresponding main release.  E.g. if
 802the variable is set to "-rc", then all "1.0-rcX" tags will appear before
 803"1.0".  If specified multiple times, once per suffix, then the order of
 804suffixes in the configuration will determine the sorting order of tagnames
 805with those suffixes.  E.g. if "-pre" appears before "-rc" in the
 806configuration, then all "1.0-preX" tags will be listed before any
 807"1.0-rcX" tags.  The placement of the main release tag relative to tags
 808with various suffixes can be determined by specifying the empty suffix
 809among those other suffixes.  E.g. if the suffixes "-rc", "", "-ck" and
 810"-bfs" appear in the configuration in this order, then all "v4.8-rcX" tags
 811are listed first, followed by "v4.8", then "v4.8-ckX" and finally
 812"v4.8-bfsX".
 813+
 814If more than one suffixes match the same tagname, then that tagname will
 815be sorted according to the suffix which starts at the earliest position in
 816the tagname.  If more than one different matching suffixes start at
 817that earliest position, then that tagname will be sorted according to the
 818longest of those suffixes.
 819The sorting order between different suffixes is undefined if they are
 820in multiple config files.
 821
 822web.browser::
 823        Specify a web browser that may be used by some commands.
 824        Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
 825        may use it.
 826
 827worktree.guessRemote::
 828        With `add`, if no branch argument, and neither of `-b` nor
 829        `-B` nor `--detach` are given, the command defaults to
 830        creating a new branch from HEAD.  If `worktree.guessRemote` is
 831        set to true, `worktree add` tries to find a remote-tracking
 832        branch whose name uniquely matches the new branch name.  If
 833        such a branch exists, it is checked out and set as "upstream"
 834        for the new branch.  If no such match can be found, it falls
 835        back to creating a new branch from the current HEAD.
