   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.

 356
 357grep.lineNumber::
 358        If set to true, enable `-n` option by default.
 359
 360grep.column::
 361        If set to true, enable the `--column` option by default.
 362
 363grep.patternType::
 364        Set the default matching behavior. Using a value of 'basic', 'extended',
 365        'fixed', or 'perl' will enable the `--basic-regexp`, `--extended-regexp`,
 366        `--fixed-strings`, or `--perl-regexp` option accordingly, while the
 367        value 'default' will return to the default matching behavior.
 368
 369grep.extendedRegexp::
 370        If set to true, enable `--extended-regexp` option by default. This
 371        option is ignored when the `grep.patternType` option is set to a value
 372        other than 'default'.
 373
 374grep.threads::
 375        Number of grep worker threads to use.
 376        See `grep.threads` in linkgit:git-grep[1] for more information.
 377
 378grep.fallbackToNoIndex::
 379        If set to true, fall back to git grep --no-index if git grep
 380        is executed outside of a git repository.  Defaults to false.
 381
 382gpg.program::
 383        Use this custom program instead of "`gpg`" found on `$PATH` when
 384        making or verifying a PGP signature. The program must support the
 385        same command-line interface as GPG, namely, to verify a detached
 386        signature, "`gpg --verify $file - <$signature`" is run, and the
 387        program is expected to signal a good signature by exiting with
 388        code 0, and to generate an ASCII-armored detached signature, the
 389        standard input of "`gpg -bsau $key`" is fed with the contents to be
 390        signed, and the program is expected to send the result to its
 391        standard output.
 392
 393gpg.format::
 394        Specifies which key format to use when signing with `--gpg-sign`.
 395        Default is "openpgp" and another possible value is "x509".
 396
 397gpg.<format>.program::
 398        Use this to customize the program used for the signing format you
 399        chose. (see `gpg.program` and `gpg.format`) `gpg.program` can still
 400        be used as a legacy synonym for `gpg.openpgp.program`. The default
 401        value for `gpg.x509.program` is "gpgsm".
 402
 403include::gui-config.txt[]
 404
 405guitool.<name>.cmd::
 406        Specifies the shell command line to execute when the corresponding item
 407        of the linkgit:git-gui[1] `Tools` menu is invoked. This option is
 408        mandatory for every tool. The command is executed from the root of
 409        the working directory, and in the environment it receives the name of
 410        the tool as `GIT_GUITOOL`, the name of the currently selected file as
 411        'FILENAME', and the name of the current branch as 'CUR_BRANCH' (if
 412        the head is detached, 'CUR_BRANCH' is empty).
 413
 414guitool.<name>.needsFile::
 415        Run the tool only if a diff is selected in the GUI. It guarantees
 416        that 'FILENAME' is not empty.
 417
 418guitool.<name>.noConsole::
 419        Run the command silently, without creating a window to display its
 420        output.
 421
 422guitool.<name>.noRescan::
 423        Don't rescan the working directory for changes after the tool
 424        finishes execution.
 425
 426guitool.<name>.confirm::
 427        Show a confirmation dialog before actually running the tool.
 428
 429guitool.<name>.argPrompt::
 430        Request a string argument from the user, and pass it to the tool
 431        through the `ARGS` environment variable. Since requesting an
 432        argument implies confirmation, the 'confirm' option has no effect
 433        if this is enabled. If the option is set to 'true', 'yes', or '1',
 434        the dialog uses a built-in generic prompt; otherwise the exact
 435        value of the variable is used.
 436
 437guitool.<name>.revPrompt::
 438        Request a single valid revision from the user, and set the
 439        `REVISION` environment variable. In other aspects this option
 440        is similar to 'argPrompt', and can be used together with it.
 441
 442guitool.<name>.revUnmerged::
 443        Show only unmerged branches in the 'revPrompt' subdialog.
 444        This is useful for tools similar to merge or rebase, but not
 445        for things like checkout or reset.
 446
 447guitool.<name>.title::
 448        Specifies the title to use for the prompt dialog. The default
 449        is the tool name.
 450
 451guitool.<name>.prompt::
 452        Specifies the general prompt string to display at the top of
 453        the dialog, before subsections for 'argPrompt' and 'revPrompt'.
 454        The default value includes the actual command.
 455
 456help.browser::
 457        Specify the browser that will be used to display help in the
 458        'web' format. See linkgit:git-help[1].
 459
 460help.format::
 461        Override the default help format used by linkgit:git-help[1].
 462        Values 'man', 'info', 'web' and 'html' are supported. 'man' is
 463        the default. 'web' and 'html' are the same.
 464
 465help.autoCorrect::
 466        Automatically correct and execute mistyped commands after
 467        waiting for the given number of deciseconds (0.1 sec). If more
 468        than one command can be deduced from the entered text, nothing
 469        will be executed.  If the value of this option is negative,
 470        the corrected command will be executed immediately. If the
 471        value is 0 - the command will be just shown but not executed.
 472        This is the default.
 473
 474help.htmlPath::
 475        Specify the path where the HTML documentation resides. File system paths
 476        and URLs are supported. HTML pages will be prefixed with this path when
 477        help is displayed in the 'web' format. This defaults to the documentation
 478        path of your Git installation.
 479
 480http.proxy::
 481        Override the HTTP proxy, normally configured using the 'http_proxy',
 482        'https_proxy', and 'all_proxy' environment variables (see `curl(1)`). In
 483        addition to the syntax understood by curl, it is possible to specify a
 484        proxy string with a user name but no password, in which case git will
 485        attempt to acquire one in the same way it does for other credentials. See
 486        linkgit:gitcredentials[7] for more information. The syntax thus is
 487        '[protocol://][user[:password]@]proxyhost[:port]'. This can be overridden
 488        on a per-remote basis; see remote.<name>.proxy
 489
 490http.proxyAuthMethod::
 491        Set the method with which to authenticate against the HTTP proxy. This
 492        only takes effect if the configured proxy string contains a user name part
 493        (i.e. is of the form 'user@host' or 'user@host:port'). This can be
 494        overridden on a per-remote basis; see `remote.<name>.proxyAuthMethod`.
 495        Both can be overridden by the `GIT_HTTP_PROXY_AUTHMETHOD` environment
 496        variable.  Possible values are:
 497+
 498--
 499* `anyauth` - Automatically pick a suitable authentication method. It is
 500  assumed that the proxy answers an unauthenticated request with a 407
 501  status code and one or more Proxy-authenticate headers with supported
 502  authentication methods. This is the default.
 503* `basic` - HTTP Basic authentication
 504* `digest` - HTTP Digest authentication; this prevents the password from being
 505  transmitted to the proxy in clear text
 506* `negotiate` - GSS-Negotiate authentication (compare the --negotiate option
 507  of `curl(1)`)
 508* `ntlm` - NTLM authentication (compare the --ntlm option of `curl(1)`)
 509--
 510
 511http.emptyAuth::
 512        Attempt authentication without seeking a username or password.  This
 513        can be used to attempt GSS-Negotiate authentication without specifying
 514        a username in the URL, as libcurl normally requires a username for
 515        authentication.
 516
 517http.delegation::
 518        Control GSSAPI credential delegation. The delegation is disabled
 519        by default in libcurl since version 7.21.7. Set parameter to tell
 520        the server what it is allowed to delegate when it comes to user
 521        credentials. Used with GSS/kerberos. Possible values are:
 522+
 523--
 524* `none` - Don't allow any delegation.
 525* `policy` - Delegates if and only if the OK-AS-DELEGATE flag is set in the
 526  Kerberos service ticket, which is a matter of realm policy.
 527* `always` - Unconditionally allow the server to delegate.
 528--
 529
 530
 531http.extraHeader::
 532        Pass an additional HTTP header when communicating with a server.  If
 533        more than one such entry exists, all of them are added as extra
 534        headers.  To allow overriding the settings inherited from the system
 535        config, an empty value will reset the extra headers to the empty list.
 536
 537http.cookieFile::
 538        The pathname of a file containing previously stored cookie lines,
 539        which should be used
 540        in the Git http session, if they match the server. The file format
 541        of the file to read cookies from should be plain HTTP headers or
 542        the Netscape/Mozilla cookie file format (see `curl(1)`).
 543        NOTE that the file specified with http.cookieFile is used only as
 544        input unless http.saveCookies is set.
 545
 546http.saveCookies::
 547        If set, store cookies received during requests to the file specified by
 548        http.cookieFile. Has no effect if http.cookieFile is unset.
 549
 550http.sslVersion::
 551        The SSL version to use when negotiating an SSL connection, if you
 552        want to force the default.  The available and default version
 553        depend on whether libcurl was built against NSS or OpenSSL and the
 554        particular configuration of the crypto library in use. Internally
 555        this sets the 'CURLOPT_SSL_VERSION' option; see the libcurl
 556        documentation for more details on the format of this option and
 557        for the ssl version supported. Actually the possible values of
 558        this option are:
 559
 560        - sslv2
 561        - sslv3
 562        - tlsv1
 563        - tlsv1.0
 564        - tlsv1.1
 565        - tlsv1.2
 566        - tlsv1.3
 567
 568+
 569Can be overridden by the `GIT_SSL_VERSION` environment variable.
 570To force git to use libcurl's default ssl version and ignore any
 571explicit http.sslversion option, set `GIT_SSL_VERSION` to the
 572empty string.
 573
 574http.sslCipherList::
 575  A list of SSL ciphers to use when negotiating an SSL connection.
 576  The available ciphers depend on whether libcurl was built against
 577  NSS or OpenSSL and the particular configuration of the crypto
 578  library in use.  Internally this sets the 'CURLOPT_SSL_CIPHER_LIST'
 579  option; see the libcurl documentation for more details on the format
 580  of this list.
 581+
 582Can be overridden by the `GIT_SSL_CIPHER_LIST` environment variable.
 583To force git to use libcurl's default cipher list and ignore any
 584explicit http.sslCipherList option, set `GIT_SSL_CIPHER_LIST` to the
 585empty string.
 586
 587http.sslVerify::
 588        Whether to verify the SSL certificate when fetching or pushing
 589        over HTTPS. Defaults to true. Can be overridden by the
 590        `GIT_SSL_NO_VERIFY` environment variable.
 591
 592http.sslCert::
 593        File containing the SSL certificate when fetching or pushing
 594        over HTTPS. Can be overridden by the `GIT_SSL_CERT` environment
 595        variable.
 596
 597http.sslKey::
 598        File containing the SSL private key when fetching or pushing
 599        over HTTPS. Can be overridden by the `GIT_SSL_KEY` environment
 600        variable.
 601
 602http.sslCertPasswordProtected::
 603        Enable Git's password prompt for the SSL certificate.  Otherwise
 604        OpenSSL will prompt the user, possibly many times, if the
 605        certificate or private key is encrypted.  Can be overridden by the
 606        `GIT_SSL_CERT_PASSWORD_PROTECTED` environment variable.
 607
 608http.sslCAInfo::
 609        File containing the certificates to verify the peer with when
 610        fetching or pushing over HTTPS. Can be overridden by the
 611        `GIT_SSL_CAINFO` environment variable.
 612
 613http.sslCAPath::
 614        Path containing files with the CA certificates to verify the peer
 615        with when fetching or pushing over HTTPS. Can be overridden
 616        by the `GIT_SSL_CAPATH` environment variable.
 617
 618http.sslBackend::
 619        Name of the SSL backend to use (e.g. "openssl" or "schannel").
 620        This option is ignored if cURL lacks support for choosing the SSL
 621        backend at runtime.
 622
 623http.schannelCheckRevoke::
 624        Used to enforce or disable certificate revocation checks in cURL
 625        when http.sslBackend is set to "schannel". Defaults to `true` if
 626        unset. Only necessary to disable this if Git consistently errors
 627        and the message is about checking the revocation status of a
 628        certificate. This option is ignored if cURL lacks support for
 629        setting the relevant SSL option at runtime.
 630
 631http.schannelUseSSLCAInfo::
 632        As of cURL v7.60.0, the Secure Channel backend can use the
 633        certificate bundle provided via `http.sslCAInfo`, but that would
 634        override the Windows Certificate Store. Since this is not desirable
 635        by default, Git will tell cURL not to use that bundle by default
 636        when the `schannel` backend was configured via `http.sslBackend`,
 637        unless `http.schannelUseSSLCAInfo` overrides this behavior.
 638
 639http.pinnedpubkey::
 640        Public key of the https service. It may either be the filename of
 641        a PEM or DER encoded public key file or a string starting with
 642        'sha256//' followed by the base64 encoded sha256 hash of the
 643        public key. See also libcurl 'CURLOPT_PINNEDPUBLICKEY'. git will
 644        exit with an error if this option is set but not supported by
 645        cURL.
 646
 647http.sslTry::
 648        Attempt to use AUTH SSL/TLS and encrypted data transfers
 649        when connecting via regular FTP protocol. This might be needed
 650        if the FTP server requires it for security reasons or you wish
 651        to connect securely whenever remote FTP server supports it.
 652        Default is false since it might trigger certificate verification
 653        errors on misconfigured servers.
 654
 655http.maxRequests::
 656        How many HTTP requests to launch in parallel. Can be overridden
 657        by the `GIT_HTTP_MAX_REQUESTS` environment variable. Default is 5.
 658
 659http.minSessions::
 660        The number of curl sessions (counted across slots) to be kept across
 661        requests. They will not be ended with curl_easy_cleanup() until
 662        http_cleanup() is invoked. If USE_CURL_MULTI is not defined, this
 663        value will be capped at 1. Defaults to 1.
 664
 665http.postBuffer::
 666        Maximum size in bytes of the buffer used by smart HTTP
 667        transports when POSTing data to the remote system.
 668        For requests larger than this buffer size, HTTP/1.1 and
 669        Transfer-Encoding: chunked is used to avoid creating a
 670        massive pack file locally.  Default is 1 MiB, which is
 671        sufficient for most requests.
 672
 673http.lowSpeedLimit, http.lowSpeedTime::
 674        If the HTTP transfer speed is less than 'http.lowSpeedLimit'
 675        for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
 676        Can be overridden by the `GIT_HTTP_LOW_SPEED_LIMIT` and
 677        `GIT_HTTP_LOW_SPEED_TIME` environment variables.
 678
 679http.noEPSV::
 680        A boolean which disables using of EPSV ftp command by curl.
 681        This can helpful with some "poor" ftp servers which don't
 682        support EPSV mode. Can be overridden by the `GIT_CURL_FTP_NO_EPSV`
 683        environment variable. Default is false (curl will use EPSV).
 684
 685http.userAgent::
 686        The HTTP USER_AGENT string presented to an HTTP server.  The default
 687        value represents the version of the client Git such as git/1.7.1.
 688        This option allows you to override this value to a more common value
 689        such as Mozilla/4.0.  This may be necessary, for instance, if
 690        connecting through a firewall that restricts HTTP connections to a set
 691        of common USER_AGENT strings (but not including those like git/1.7.1).
 692        Can be overridden by the `GIT_HTTP_USER_AGENT` environment variable.
 693
 694http.followRedirects::
 695        Whether git should follow HTTP redirects. If set to `true`, git
 696        will transparently follow any redirect issued by a server it
 697        encounters. If set to `false`, git will treat all redirects as
 698        errors. If set to `initial`, git will follow redirects only for
 699        the initial request to a remote, but not for subsequent
 700        follow-up HTTP requests. Since git uses the redirected URL as
 701        the base for the follow-up requests, this is generally
 702        sufficient. The default is `initial`.
 703
 704http.<url>.*::
 705        Any of the http.* options above can be applied selectively to some URLs.
 706        For a config key to match a URL, each element of the config key is
 707        compared to that of the URL, in the following order:
 708+
 709--
 710. Scheme (e.g., `https` in `https://example.com/`). This field
 711  must match exactly between the config key and the URL.
 712
 713. Host/domain name (e.g., `example.com` in `https://example.com/`).
 714  This field must match between the config key and the URL. It is
 715  possible to specify a `*` as part of the host name to match all subdomains
 716  at this level. `https://*.example.com/` for example would match
 717  `https://foo.example.com/`, but not `https://foo.bar.example.com/`.
 718
 719. Port number (e.g., `8080` in `http://example.com:8080/`).
 720  This field must match exactly between the config key and the URL.
 721  Omitted port numbers are automatically converted to the correct
 722  default for the scheme before matching.
 723
 724. Path (e.g., `repo.git` in `https://example.com/repo.git`). The
 725  path field of the config key must match the path field of the URL
 726  either exactly or as a prefix of slash-delimited path elements.  This means
 727  a config key with path `foo/` matches URL path `foo/bar`.  A prefix can only
 728  match on a slash (`/`) boundary.  Longer matches take precedence (so a config
 729  key with path `foo/bar` is a better match to URL path `foo/bar` than a config
 730  key with just path `foo/`).
 731
 732. User name (e.g., `user` in `https://user@example.com/repo.git`). If
 733  the config key has a user name it must match the user name in the
 734  URL exactly. If the config key does not have a user name, that
 735  config key will match a URL with any user name (including none),
 736  but at a lower precedence than a config key with a user name.
 737--
 738+
 739The list above is ordered by decreasing precedence; a URL that matches
 740a config key's path is preferred to one that matches its user name. For example,
 741if the URL is `https://user@example.com/foo/bar` a config key match of
 742`https://example.com/foo` will be preferred over a config key match of
 743`https://user@example.com`.
 744+
 745All URLs are normalized before attempting any matching (the password part,
 746if embedded in the URL, is always ignored for matching purposes) so that
 747equivalent URLs that are simply spelled differently will match properly.
 748Environment variable settings always override any matches.  The URLs that are
 749matched against are those given directly to Git commands.  This means any URLs
 750visited as a result of a redirection do not participate in matching.
 751
 752ssh.variant::
 753        By default, Git determines the command line arguments to use
 754        based on the basename of the configured SSH command (configured
 755        using the environment variable `GIT_SSH` or `GIT_SSH_COMMAND` or
 756        the config setting `core.sshCommand`). If the basename is
 757        unrecognized, Git will attempt to detect support of OpenSSH
 758        options by first invoking the configured SSH command with the
 759        `-G` (print configuration) option and will subsequently use
 760        OpenSSH options (if that is successful) or no options besides
 761        the host and remote command (if it fails).
 762+
 763The config variable `ssh.variant` can be set to override this detection.
 764Valid values are `ssh` (to use OpenSSH options), `plink`, `putty`,
 765`tortoiseplink`, `simple` (no options except the host and remote command).
 766The default auto-detection can be explicitly requested using the value
 767`auto`.  Any other value is treated as `ssh`.  This setting can also be
 768overridden via the environment variable `GIT_SSH_VARIANT`.
 769+
 770The current command-line parameters used for each variant are as
 771follows:
 772+
 773--
 774
 775* `ssh` - [-p port] [-4] [-6] [-o option] [username@]host command
 776
 777* `simple` - [username@]host command
 778
 779* `plink` or `putty` - [-P port] [-4] [-6] [username@]host command
 780
 781* `tortoiseplink` - [-P port] [-4] [-6] -batch [username@]host command
 782
 783--
 784+
 785Except for the `simple` variant, command-line parameters are likely to
 786change as git gains new features.
 787
 788i18n.commitEncoding::
 789        Character encoding the commit messages are stored in; Git itself
 790        does not care per se, but this information is necessary e.g. when
 791        importing commits from emails or in the gitk graphical history
 792        browser (and possibly at other places in the future or in other
 793        porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.
 794
 795i18n.logOutputEncoding::
 796        Character encoding the commit messages are converted to when
 797        running 'git log' and friends.
 798
 799imap::
 800        The configuration variables in the 'imap' section are described
 801        in linkgit:git-imap-send[1].
 802
 803index.threads::
 804        Specifies the number of threads to spawn when loading the index.
 805        This is meant to reduce index load time on multiprocessor machines.
 806        Specifying 0 or 'true' will cause Git to auto-detect the number of
 807        CPU's and set the number of threads accordingly. Specifying 1 or
 808        'false' will disable multithreading. Defaults to 'true'.
 809
 810index.version::
 811        Specify the version with which new index files should be
 812        initialized.  This does not affect existing repositories.
 813
 814init.templateDir::
 815        Specify the directory from which templates will be copied.
 816        (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].)
 817
 818instaweb.browser::
 819        Specify the program that will be used to browse your working
 820        repository in gitweb. See linkgit:git-instaweb[1].
 821
 822instaweb.httpd::
 823        The HTTP daemon command-line to start gitweb on your working
 824        repository. See linkgit:git-instaweb[1].
 825
 826instaweb.local::
 827        If true the web server started by linkgit:git-instaweb[1] will
 828        be bound to the local IP (127.0.0.1).
 829
 830instaweb.modulePath::
 831        The default module path for linkgit:git-instaweb[1] to use
 832        instead of /usr/lib/apache2/modules.  Only used if httpd
 833        is Apache.
 834
 835instaweb.port::
 836        The port number to bind the gitweb httpd to. See
 837        linkgit:git-instaweb[1].
 838
 839interactive.singleKey::
 840        In interactive commands, allow the user to provide one-letter
 841        input with a single key (i.e., without hitting enter).
 842        Currently this is used by the `--patch` mode of
 843        linkgit:git-add[1], linkgit:git-checkout[1], linkgit:git-commit[1],
 844        linkgit:git-reset[1], and linkgit:git-stash[1]. Note that this
 845        setting is silently ignored if portable keystroke input
 846        is not available; requires the Perl module Term::ReadKey.
 847
 848interactive.diffFilter::
 849        When an interactive command (such as `git add --patch`) shows
 850        a colorized diff, git will pipe the diff through the shell
 851        command defined by this configuration variable. The command may
 852        mark up the diff further for human consumption, provided that it
 853        retains a one-to-one correspondence with the lines in the
 854        original diff. Defaults to disabled (no filtering).
 855
 856log.abbrevCommit::
 857        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
 858        linkgit:git-whatchanged[1] assume `--abbrev-commit`. You may
 859        override this option with `--no-abbrev-commit`.
 860
 861log.date::
 862        Set the default date-time mode for the 'log' command.
 863        Setting a value for log.date is similar to using 'git log''s
 864        `--date` option.  See linkgit:git-log[1] for details.
 865
 866log.decorate::
 867        Print out the ref names of any commits that are shown by the log
 868        command. If 'short' is specified, the ref name prefixes 'refs/heads/',
 869        'refs/tags/' and 'refs/remotes/' will not be printed. If 'full' is
 870        specified, the full ref name (including prefix) will be printed.
 871        If 'auto' is specified, then if the output is going to a terminal,
 872        the ref names are shown as if 'short' were given, otherwise no ref
 873        names are shown. This is the same as the `--decorate` option
 874        of the `git log`.
 875
 876log.follow::
 877        If `true`, `git log` will act as if the `--follow` option was used when
 878        a single <path> is given.  This has the same limitations as `--follow`,
 879        i.e. it cannot be used to follow multiple files and does not work well
 880        on non-linear history.
 881
 882log.graphColors::
 883        A list of colors, separated by commas, that can be used to draw
 884        history lines in `git log --graph`.
 885
 886log.showRoot::
 887        If true, the initial commit will be shown as a big creation event.
 888        This is equivalent to a diff against an empty tree.
 889        Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
 890        normally hide the root commit will now show it. True by default.
 891
 892log.showSignature::
 893        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
 894        linkgit:git-whatchanged[1] assume `--show-signature`.
 895
 896log.mailmap::
 897        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
 898        linkgit:git-whatchanged[1] assume `--use-mailmap`.
 899
 900mailinfo.scissors::
 901        If true, makes linkgit:git-mailinfo[1] (and therefore
 902        linkgit:git-am[1]) act by default as if the --scissors option
 903        was provided on the command-line. When active, this features
 904        removes everything from the message body before a scissors
 905        line (i.e. consisting mainly of ">8", "8<" and "-").
 906
 907mailmap.file::
 908        The location of an augmenting mailmap file. The default
 909        mailmap, located in the root of the repository, is loaded
 910        first, then the mailmap file pointed to by this variable.
 911        The location of the mailmap file may be in a repository
 912        subdirectory, or somewhere outside of the repository itself.
 913        See linkgit:git-shortlog[1] and linkgit:git-blame[1].
 914
 915mailmap.blob::
 916        Like `mailmap.file`, but consider the value as a reference to a
 917        blob in the repository. If both `mailmap.file` and
 918        `mailmap.blob` are given, both are parsed, with entries from
 919        `mailmap.file` taking precedence. In a bare repository, this
 920        defaults to `HEAD:.mailmap`. In a non-bare repository, it
 921        defaults to empty.
 922
 923man.viewer::
 924        Specify the programs that may be used to display help in the
 925        'man' format. See linkgit:git-help[1].
 926
 927man.<tool>.cmd::
 928        Specify the command to invoke the specified man viewer. The
 929        specified command is evaluated in shell with the man page
 930        passed as argument. (See linkgit:git-help[1].)
 931
 932man.<tool>.path::
 933        Override the path for the given tool that may be used to
 934        display help in the 'man' format. See linkgit:git-help[1].
 935
 936include::merge-config.txt[]
 937
 938mergetool.<tool>.path::
 939        Override the path for the given tool.  This is useful in case
 940        your tool is not in the PATH.
 941
 942mergetool.<tool>.cmd::
 943        Specify the command to invoke the specified merge tool.  The
 944        specified command is evaluated in shell with the following
 945        variables available: 'BASE' is the name of a temporary file
 946        containing the common base of the files to be merged, if available;
 947        'LOCAL' is the name of a temporary file containing the contents of
 948        the file on the current branch; 'REMOTE' is the name of a temporary
 949        file containing the contents of the file from the branch being
 950        merged; 'MERGED' contains the name of the file to which the merge
 951        tool should write the results of a successful merge.
 952
 953mergetool.<tool>.trustExitCode::
 954        For a custom merge command, specify whether the exit code of
 955        the merge command can be used to determine whether the merge was
 956        successful.  If this is not set to true then the merge target file
 957        timestamp is checked and the merge assumed to have been successful
 958        if the file has been updated, otherwise the user is prompted to
 959        indicate the success of the merge.
 960
 961mergetool.meld.hasOutput::
 962        Older versions of `meld` do not support the `--output` option.
 963        Git will attempt to detect whether `meld` supports `--output`
 964        by inspecting the output of `meld --help`.  Configuring
 965        `mergetool.meld.hasOutput` will make Git skip these checks and
 966        use the configured value instead.  Setting `mergetool.meld.hasOutput`
 967        to `true` tells Git to unconditionally use the `--output` option,
 968        and `false` avoids using `--output`.
 969
 970mergetool.keepBackup::
 971        After performing a merge, the original file with conflict markers
 972        can be saved as a file with a `.orig` extension.  If this variable
 973        is set to `false` then this file is not preserved.  Defaults to
 974        `true` (i.e. keep the backup files).
 975
 976mergetool.keepTemporaries::
 977        When invoking a custom merge tool, Git uses a set of temporary
 978        files to pass to the tool. If the tool returns an error and this
 979        variable is set to `true`, then these temporary files will be
 980        preserved, otherwise they will be removed after the tool has
 981        exited. Defaults to `false`.
 982
 983mergetool.writeToTemp::
 984        Git writes temporary 'BASE', 'LOCAL', and 'REMOTE' versions of
 985        conflicting files in the worktree by default.  Git will attempt
 986        to use a temporary directory for these files when set `true`.
 987        Defaults to `false`.
 988
 989mergetool.prompt::
 990        Prompt before each invocation of the merge resolution program.
 991
 992notes.mergeStrategy::
 993        Which merge strategy to choose by default when resolving notes
 994        conflicts.  Must be one of `manual`, `ours`, `theirs`, `union`, or
 995        `cat_sort_uniq`.  Defaults to `manual`.  See "NOTES MERGE STRATEGIES"
 996        section of linkgit:git-notes[1] for more information on each strategy.
 997
 998notes.<name>.mergeStrategy::
 999        Which merge strategy to choose when doing a notes merge into
1000        refs/notes/<name>.  This overrides the more general
1001        "notes.mergeStrategy".  See the "NOTES MERGE STRATEGIES" section in
1002        linkgit:git-notes[1] for more information on the available strategies.
1003
1004notes.displayRef::
1005        The (fully qualified) refname from which to show notes when
1006        showing commit messages.  The value of this variable can be set
1007        to a glob, in which case notes from all matching refs will be
1008        shown.  You may also specify this configuration variable
1009        several times.  A warning will be issued for refs that do not
1010        exist, but a glob that does not match any refs is silently
1011        ignored.
1012+
1013This setting can be overridden with the `GIT_NOTES_DISPLAY_REF`
1014environment variable, which must be a colon separated list of refs or
1015globs.
1016+
1017The effective value of "core.notesRef" (possibly overridden by
1018GIT_NOTES_REF) is also implicitly added to the list of refs to be
1019displayed.
1020
1021notes.rewrite.<command>::
1022        When rewriting commits with <command> (currently `amend` or
1023        `rebase`) and this variable is set to `true`, Git
1024        automatically copies your notes from the original to the
1025        rewritten commit.  Defaults to `true`, but see
1026        "notes.rewriteRef" below.
1027
1028notes.rewriteMode::
1029        When copying notes during a rewrite (see the
1030        "notes.rewrite.<command>" option), determines what to do if
1031        the target commit already has a note.  Must be one of
1032        `overwrite`, `concatenate`, `cat_sort_uniq`, or `ignore`.
1033        Defaults to `concatenate`.
1034+
1035This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
1036environment variable.
1037
1038notes.rewriteRef::
1039        When copying notes during a rewrite, specifies the (fully
1040        qualified) ref whose notes should be copied.  The ref may be a
1041        glob, in which case notes in all matching refs will be copied.
1042        You may also specify this configuration several times.
1043+
1044Does not have a default value; you must configure this variable to
1045enable note rewriting.  Set it to `refs/notes/commits` to enable
1046rewriting for the default commit notes.
1047+
1048This setting can be overridden with the `GIT_NOTES_REWRITE_REF`
1049environment variable, which must be a colon separated list of refs or
1050globs.
1051
1052pack.window::
1053        The size of the window used by linkgit:git-pack-objects[1] when no
1054        window size is given on the command line. Defaults to 10.
1055
1056pack.depth::
1057        The maximum delta depth used by linkgit:git-pack-objects[1] when no
1058        maximum depth is given on the command line. Defaults to 50.
1059        Maximum value is 4095.
1060
1061pack.windowMemory::
1062        The maximum size of memory that is consumed by each thread
1063        in linkgit:git-pack-objects[1] for pack window memory when
1064        no limit is given on the command line.  The value can be
1065        suffixed with "k", "m", or "g".  When left unconfigured (or
1066        set explicitly to 0), there will be no limit.
1067
1068pack.compression::
1069        An integer -1..9, indicating the compression level for objects
1070        in a pack file. -1 is the zlib default. 0 means no
1071        compression, and 1..9 are various speed/size tradeoffs, 9 being
1072        slowest.  If not set,  defaults to core.compression.  If that is
1073        not set,  defaults to -1, the zlib default, which is "a default
1074        compromise between speed and compression (currently equivalent
1075        to level 6)."
1076+
1077Note that changing the compression level will not automatically recompress
1078all existing objects. You can force recompression by passing the -F option
1079to linkgit:git-repack[1].
1080
1081pack.island::
1082        An extended regular expression configuring a set of delta
1083        islands. See "DELTA ISLANDS" in linkgit:git-pack-objects[1]
1084        for details.
1085
1086pack.islandCore::
1087        Specify an island name which gets to have its objects be
1088        packed first. This creates a kind of pseudo-pack at the front
1089        of one pack, so that the objects from the specified island are
1090        hopefully faster to copy into any pack that should be served
1091        to a user requesting these objects. In practice this means
1092        that the island specified should likely correspond to what is
1093        the most commonly cloned in the repo. See also "DELTA ISLANDS"
1094        in linkgit:git-pack-objects[1].
1095
1096pack.deltaCacheSize::
1097        The maximum memory in bytes used for caching deltas in
1098        linkgit:git-pack-objects[1] before writing them out to a pack.
1099        This cache is used to speed up the writing object phase by not
1100        having to recompute the final delta result once the best match
1101        for all objects is found.  Repacking large repositories on machines
1102        which are tight with memory might be badly impacted by this though,
1103        especially if this cache pushes the system into swapping.
1104        A value of 0 means no limit. The smallest size of 1 byte may be
1105        used to virtually disable this cache. Defaults to 256 MiB.
1106
1107pack.deltaCacheLimit::
1108        The maximum size of a delta, that is cached in
1109        linkgit:git-pack-objects[1]. This cache is used to speed up the
1110        writing object phase by not having to recompute the final delta
1111        result once the best match for all objects is found.
1112        Defaults to 1000. Maximum value is 65535.
1113
1114pack.threads::
1115        Specifies the number of threads to spawn when searching for best
1116        delta matches.  This requires that linkgit:git-pack-objects[1]
1117        be compiled with pthreads otherwise this option is ignored with a
1118        warning. This is meant to reduce packing time on multiprocessor
1119        machines. The required amount of memory for the delta search window
1120        is however multiplied by the number of threads.
1121        Specifying 0 will cause Git to auto-detect the number of CPU's
1122        and set the number of threads accordingly.
1123
1124pack.indexVersion::
1125        Specify the default pack index version.  Valid values are 1 for
1126        legacy pack index used by Git versions prior to 1.5.2, and 2 for
1127        the new pack index with capabilities for packs larger than 4 GB
1128        as well as proper protection against the repacking of corrupted
1129        packs.  Version 2 is the default.  Note that version 2 is enforced
1130        and this config option ignored whenever the corresponding pack is
1131        larger than 2 GB.
1132+
1133If you have an old Git that does not understand the version 2 `*.idx` file,
1134cloning or fetching over a non native protocol (e.g. "http")
1135that will copy both `*.pack` file and corresponding `*.idx` file from the
1136other side may give you a repository that cannot be accessed with your
1137older version of Git. If the `*.pack` file is smaller than 2 GB, however,
1138you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
1139the `*.idx` file.
1140
1141pack.packSizeLimit::
1142        The maximum size of a pack.  This setting only affects
1143        packing to a file when repacking, i.e. the git:// protocol
1144        is unaffected.  It can be overridden by the `--max-pack-size`
1145        option of linkgit:git-repack[1].  Reaching this limit results
1146        in the creation of multiple packfiles; which in turn prevents
1147        bitmaps from being created.
1148        The minimum size allowed is limited to 1 MiB.
1149        The default is unlimited.
1150        Common unit suffixes of 'k', 'm', or 'g' are
1151        supported.
1152
1153pack.useBitmaps::
1154        When true, git will use pack bitmaps (if available) when packing
1155        to stdout (e.g., during the server side of a fetch). Defaults to
1156        true. You should not generally need to turn this off unless
1157        you are debugging pack bitmaps.
1158
1159pack.writeBitmaps (deprecated)::
1160        This is a deprecated synonym for `repack.writeBitmaps`.
1161
1162pack.writeBitmapHashCache::
1163        When true, git will include a "hash cache" section in the bitmap
1164        index (if one is written). This cache can be used to feed git's
1165        delta heuristics, potentially leading to better deltas between
1166        bitmapped and non-bitmapped objects (e.g., when serving a fetch
1167        between an older, bitmapped pack and objects that have been
1168        pushed since the last gc). The downside is that it consumes 4
1169        bytes per object of disk space, and that JGit's bitmap
1170        implementation does not understand it, causing it to complain if
1171        Git and JGit are used on the same repository. Defaults to false.
1172
1173pager.<cmd>::
1174        If the value is boolean, turns on or off pagination of the
1175        output of a particular Git subcommand when writing to a tty.
1176        Otherwise, turns on pagination for the subcommand using the
1177        pager specified by the value of `pager.<cmd>`.  If `--paginate`
1178        or `--no-pager` is specified on the command line, it takes
1179        precedence over this option.  To disable pagination for all
1180        commands, set `core.pager` or `GIT_PAGER` to `cat`.
1181
1182pretty.<name>::
1183        Alias for a --pretty= format string, as specified in
1184        linkgit:git-log[1]. Any aliases defined here can be used just
1185        as the built-in pretty formats could. For example,
1186        running `git config pretty.changelog "format:* %H %s"`
1187        would cause the invocation `git log --pretty=changelog`
1188        to be equivalent to running `git log "--pretty=format:* %H %s"`.
1189        Note that an alias with the same name as a built-in format
1190        will be silently ignored.
1191
1192protocol.allow::
1193        If set, provide a user defined default policy for all protocols which
1194        don't explicitly have a policy (`protocol.<name>.allow`).  By default,
1195        if unset, known-safe protocols (http, https, git, ssh, file) have a
1196        default policy of `always`, known-dangerous protocols (ext) have a
1197        default policy of `never`, and all other protocols have a default
1198        policy of `user`.  Supported policies:
1199+
1200--
1201
1202* `always` - protocol is always able to be used.
1203
1204* `never` - protocol is never able to be used.
1205
1206* `user` - protocol is only able to be used when `GIT_PROTOCOL_FROM_USER` is
1207  either unset or has a value of 1.  This policy should be used when you want a
1208  protocol to be directly usable by the user but don't want it used by commands which
1209  execute clone/fetch/push commands without user input, e.g. recursive
1210  submodule initialization.
1211
1212--
1213
1214protocol.<name>.allow::
1215        Set a policy to be used by protocol `<name>` with clone/fetch/push
1216        commands. See `protocol.allow` above for the available policies.
1217+
1218The protocol names currently used by git are:
1219+
1220--
1221  - `file`: any local file-based path (including `file://` URLs,
1222    or local paths)
1223
1224  - `git`: the anonymous git protocol over a direct TCP
1225    connection (or proxy, if configured)
1226
1227  - `ssh`: git over ssh (including `host:path` syntax,
1228    `ssh://`, etc).
1229
1230  - `http`: git over http, both "smart http" and "dumb http".
1231    Note that this does _not_ include `https`; if you want to configure
1232    both, you must do so individually.
1233
1234  - any external helpers are named by their protocol (e.g., use
1235    `hg` to allow the `git-remote-hg` helper)
1236--
1237
1238protocol.version::
1239        Experimental. If set, clients will attempt to communicate with a
1240        server using the specified protocol version.  If unset, no
1241        attempt will be made by the client to communicate using a
1242        particular protocol version, this results in protocol version 0
1243        being used.
1244        Supported versions:
1245+
1246--
1247
1248* `0` - the original wire protocol.
1249
1250* `1` - the original wire protocol with the addition of a version string
1251  in the initial response from the server.
1252
1253* `2` - link:technical/protocol-v2.html[wire protocol version 2].

1265remote.pushDefault::
1266        The remote to push to by default.  Overrides
1267        `branch.<name>.remote` for all branches, and is overridden by
1268        `branch.<name>.pushRemote` for specific branches.
1269
1270remote.<name>.url::
1271        The URL of a remote repository.  See linkgit:git-fetch[1] or
1272        linkgit:git-push[1].
1273
1274remote.<name>.pushurl::
1275        The push URL of a remote repository.  See linkgit:git-push[1].
1276
1277remote.<name>.proxy::
1278        For remotes that require curl (http, https and ftp), the URL to
1279        the proxy to use for that remote.  Set to the empty string to
1280        disable proxying for that remote.
1281
1282remote.<name>.proxyAuthMethod::
1283        For remotes that require curl (http, https and ftp), the method to use for
1284        authenticating against the proxy in use (probably set in
1285        `remote.<name>.proxy`). See `http.proxyAuthMethod`.
1286
1287remote.<name>.fetch::
1288        The default set of "refspec" for linkgit:git-fetch[1]. See
1289        linkgit:git-fetch[1].
1290
1291remote.<name>.push::
1292        The default set of "refspec" for linkgit:git-push[1]. See
1293        linkgit:git-push[1].
1294
1295remote.<name>.mirror::
1296        If true, pushing to this remote will automatically behave
1297        as if the `--mirror` option was given on the command line.
1298
1299remote.<name>.skipDefaultUpdate::
1300        If true, this remote will be skipped by default when updating
1301        using linkgit:git-fetch[1] or the `update` subcommand of
1302        linkgit:git-remote[1].
1303
1304remote.<name>.skipFetchAll::
1305        If true, this remote will be skipped by default when updating
1306        using linkgit:git-fetch[1] or the `update` subcommand of
1307        linkgit:git-remote[1].
1308
1309remote.<name>.receivepack::
1310        The default program to execute on the remote side when pushing.  See
1311        option --receive-pack of linkgit:git-push[1].
1312
1313remote.<name>.uploadpack::
1314        The default program to execute on the remote side when fetching.  See
1315        option --upload-pack of linkgit:git-fetch-pack[1].
1316
1317remote.<name>.tagOpt::
1318        Setting this value to --no-tags disables automatic tag following when
1319        fetching from remote <name>. Setting it to --tags will fetch every
1320        tag from remote <name>, even if they are not reachable from remote
1321        branch heads. Passing these flags directly to linkgit:git-fetch[1] can
1322        override this setting. See options --tags and --no-tags of
1323        linkgit:git-fetch[1].
1324
1325remote.<name>.vcs::
1326        Setting this to a value <vcs> will cause Git to interact with
1327        the remote with the git-remote-<vcs> helper.
1328
1329remote.<name>.prune::
1330        When set to true, fetching from this remote by default will also
1331        remove any remote-tracking references that no longer exist on the
1332        remote (as if the `--prune` option was given on the command line).
1333        Overrides `fetch.prune` settings, if any.
1334
1335remote.<name>.pruneTags::
1336        When set to true, fetching from this remote by default will also
1337        remove any local tags that no longer exist on the remote if pruning
1338        is activated in general via `remote.<name>.prune`, `fetch.prune` or
1339        `--prune`. Overrides `fetch.pruneTags` settings, if any.
1340+
1341See also `remote.<name>.prune` and the PRUNING section of
1342linkgit:git-fetch[1].
1343
1344remotes.<group>::
1345        The list of remotes which are fetched by "git remote update
1346        <group>".  See linkgit:git-remote[1].
1347
1348repack.useDeltaBaseOffset::
1349        By default, linkgit:git-repack[1] creates packs that use
1350        delta-base offset. If you need to share your repository with
1351        Git older than version 1.4.4, either directly or via a dumb
1352        protocol such as http, then you need to set this option to
1353        "false" and repack. Access from old Git versions over the
1354        native protocol are unaffected by this option.
1355
1356repack.packKeptObjects::
1357        If set to true, makes `git repack` act as if
1358        `--pack-kept-objects` was passed. See linkgit:git-repack[1] for
1359        details. Defaults to `false` normally, but `true` if a bitmap
1360        index is being written (either via `--write-bitmap-index` or
1361        `repack.writeBitmaps`).
1362
1363repack.useDeltaIslands::
1364        If set to true, makes `git repack` act as if `--delta-islands`
1365        was passed. Defaults to `false`.
1366
1367repack.writeBitmaps::
1368        When true, git will write a bitmap index when packing all
1369        objects to disk (e.g., when `git repack -a` is run).  This
1370        index can speed up the "counting objects" phase of subsequent
1371        packs created for clones and fetches, at the cost of some disk
1372        space and extra time spent on the initial repack.  This has
1373        no effect if multiple packfiles are created.
1374        Defaults to false.
1375
1376rerere.autoUpdate::
1377        When set to true, `git-rerere` updates the index with the
1378        resulting contents after it cleanly resolves conflicts using
1379        previously recorded resolution.  Defaults to false.
1380
1381rerere.enabled::
1382        Activate recording of resolved conflicts, so that identical
1383        conflict hunks can be resolved automatically, should they be
1384        encountered again.  By default, linkgit:git-rerere[1] is
1385        enabled if there is an `rr-cache` directory under the
1386        `$GIT_DIR`, e.g. if "rerere" was previously used in the
1387        repository.
1388
1389reset.quiet::
1390        When set to true, 'git reset' will default to the '--quiet' option.
1391
1392include::sendemail-config.txt[]
1393
1394sequence.editor::
1395        Text editor used by `git rebase -i` for editing the rebase instruction file.
1396        The value is meant to be interpreted by the shell when it is used.
1397        It can be overridden by the `GIT_SEQUENCE_EDITOR` environment variable.
1398        When not configured the default commit message editor is used instead.
1399
1400showBranch.default::
1401        The default set of branches for linkgit:git-show-branch[1].
1402        See linkgit:git-show-branch[1].
1403
1404splitIndex.maxPercentChange::
1405        When the split index feature is used, this specifies the
1406        percent of entries the split index can contain compared to the
1407        total number of entries in both the split index and the shared
1408        index before a new shared index is written.
1409        The value should be between 0 and 100. If the value is 0 then
1410        a new shared index is always written, if it is 100 a new
1411        shared index is never written.
1412        By default the value is 20, so a new shared index is written
1413        if the number of entries in the split index would be greater
1414        than 20 percent of the total number of entries.
1415        See linkgit:git-update-index[1].
1416
1417splitIndex.sharedIndexExpire::
1418        When the split index feature is used, shared index files that
1419        were not modified since the time this variable specifies will
1420        be removed when a new shared index file is created. The value
1421        "now" expires all entries immediately, and "never" suppresses
1422        expiration altogether.
1423        The default value is "2.weeks.ago".
1424        Note that a shared index file is considered modified (for the
1425        purpose of expiration) each time a new split-index file is
1426        either created based on it or read from it.
1427        See linkgit:git-update-index[1].
1428
1429status.relativePaths::
1430        By default, linkgit:git-status[1] shows paths relative to the
1431        current directory. Setting this variable to `false` shows paths
1432        relative to the repository root (this was the default for Git
1433        prior to v1.5.4).
1434
1435status.short::
1436        Set to true to enable --short by default in linkgit:git-status[1].
1437        The option --no-short takes precedence over this variable.
1438
1439status.branch::
1440        Set to true to enable --branch by default in linkgit:git-status[1].
1441        The option --no-branch takes precedence over this variable.
1442
1443status.displayCommentPrefix::
1444        If set to true, linkgit:git-status[1] will insert a comment
1445        prefix before each output line (starting with
1446        `core.commentChar`, i.e. `#` by default). This was the
1447        behavior of linkgit:git-status[1] in Git 1.8.4 and previous.
1448        Defaults to false.
1449
1450status.renameLimit::
1451        The number of files to consider when performing rename detection
1452        in linkgit:git-status[1] and linkgit:git-commit[1]. Defaults to
1453        the value of diff.renameLimit.
1454
1455status.renames::
1456        Whether and how Git detects renames in linkgit:git-status[1] and
1457        linkgit:git-commit[1] .  If set to "false", rename detection is
1458        disabled. If set to "true", basic rename detection is enabled.
1459        If set to "copies" or "copy", Git will detect copies, as well.
1460        Defaults to the value of diff.renames.
1461
1462status.showStash::
1463        If set to true, linkgit:git-status[1] will display the number of
1464        entries currently stashed away.
1465        Defaults to false.
1466
1467status.showUntrackedFiles::
1468        By default, linkgit:git-status[1] and linkgit:git-commit[1] show
1469        files which are not currently tracked by Git. Directories which
1470        contain only untracked files, are shown with the directory name
1471        only. Showing untracked files means that Git needs to lstat() all
1472        the files in the whole repository, which might be slow on some
1473        systems. So, this variable controls how the commands displays
1474        the untracked files. Possible values are:
1475+
1476--
1477* `no` - Show no untracked files.
1478* `normal` - Show untracked files and directories.
1479* `all` - Show also individual files in untracked directories.
1480--
1481+
1482If this variable is not specified, it defaults to 'normal'.
1483This variable can be overridden with the -u|--untracked-files option
1484of linkgit:git-status[1] and linkgit:git-commit[1].
1485
1486status.submoduleSummary::
1487        Defaults to false.
1488        If this is set to a non zero number or true (identical to -1 or an
1489        unlimited number), the submodule summary will be enabled and a
1490        summary of commits for modified submodules will be shown (see
1491        --summary-limit option of linkgit:git-submodule[1]). Please note
1492        that the summary output command will be suppressed for all
1493        submodules when `diff.ignoreSubmodules` is set to 'all' or only
1494        for those submodules where `submodule.<name>.ignore=all`. The only
1495        exception to that rule is that status and commit will show staged
1496        submodule changes. To
1497        also view the summary for ignored submodules you can either use
1498        the --ignore-submodules=dirty command-line option or the 'git
1499        submodule summary' command, which shows a similar output but does
1500        not honor these settings.
1501
1502stash.showPatch::
1503        If this is set to true, the `git stash show` command without an
1504        option will show the stash entry in patch form.  Defaults to false.
1505        See description of 'show' command in linkgit:git-stash[1].
1506
1507stash.showStat::
1508        If this is set to true, the `git stash show` command without an
1509        option will show diffstat of the stash entry.  Defaults to true.
1510        See description of 'show' command in linkgit:git-stash[1].
1511
1512include::submodule-config.txt[]
1513
1514tag.forceSignAnnotated::
1515        A boolean to specify whether annotated tags created should be GPG signed.
1516        If `--annotate` is specified on the command line, it takes
1517        precedence over this option.
1518
1519tag.sort::
1520        This variable controls the sort ordering of tags when displayed by
1521        linkgit:git-tag[1]. Without the "--sort=<value>" option provided, the
1522        value of this variable will be used as the default.
1523
1524tar.umask::
1525        This variable can be used to restrict the permission bits of
1526        tar archive entries.  The default is 0002, which turns off the
1527        world write bit.  The special value "user" indicates that the
1528        archiving user's umask will be used instead.  See umask(2) and
1529        linkgit:git-archive[1].
1530
1531transfer.fsckObjects::
1532        When `fetch.fsckObjects` or `receive.fsckObjects` are
1533        not set, the value of this variable is used instead.
1534        Defaults to false.
1535+
1536When set, the fetch or receive will abort in the case of a malformed
1537object or a link to a nonexistent object. In addition, various other
1538issues are checked for, including legacy issues (see `fsck.<msg-id>`),
1539and potential security issues like the existence of a `.GIT` directory
1540or a malicious `.gitmodules` file (see the release notes for v2.2.1
1541and v2.17.1 for details). Other sanity and security checks may be
1542added in future releases.
1543+
1544On the receiving side, failing fsckObjects will make those objects
1545unreachable, see "QUARANTINE ENVIRONMENT" in
1546linkgit:git-receive-pack[1]. On the fetch side, malformed objects will
1547instead be left unreferenced in the repository.
1548+
1549Due to the non-quarantine nature of the `fetch.fsckObjects`
1550implementation it can not be relied upon to leave the object store
1551clean like `receive.fsckObjects` can.
1552+
1553As objects are unpacked they're written to the object store, so there
1554can be cases where malicious objects get introduced even though the
1555"fetch" failed, only to have a subsequent "fetch" succeed because only
1556new incoming objects are checked, not those that have already been
1557written to the object store. That difference in behavior should not be
1558relied upon. In the future, such objects may be quarantined for
1559"fetch" as well.
1560+
1561For now, the paranoid need to find some way to emulate the quarantine
1562environment if they'd like the same protection as "push". E.g. in the
1563case of an internal mirror do the mirroring in two steps, one to fetch
1564the untrusted objects, and then do a second "push" (which will use the
1565quarantine) to another internal repo, and have internal clients
1566consume this pushed-to repository, or embargo internal fetches and
1567only allow them once a full "fsck" has run (and no new fetches have
1568happened in the meantime).
1569
1570transfer.hideRefs::
1571        String(s) `receive-pack` and `upload-pack` use to decide which
1572        refs to omit from their initial advertisements.  Use more than
1573        one definition to specify multiple prefix strings. A ref that is
1574        under the hierarchies listed in the value of this variable is
1575        excluded, and is hidden when responding to `git push` or `git
1576        fetch`.  See `receive.hideRefs` and `uploadpack.hideRefs` for
1577        program-specific versions of this config.
1578+
1579You may also include a `!` in front of the ref name to negate the entry,
1580explicitly exposing it, even if an earlier entry marked it as hidden.
1581If you have multiple hideRefs values, later entries override earlier ones
1582(and entries in more-specific config files override less-specific ones).
1583+
1584If a namespace is in use, the namespace prefix is stripped from each
1585reference before it is matched against `transfer.hiderefs` patterns.
1586For example, if `refs/heads/master` is specified in `transfer.hideRefs` and
1587the current namespace is `foo`, then `refs/namespaces/foo/refs/heads/master`
1588is omitted from the advertisements but `refs/heads/master` and
1589`refs/namespaces/bar/refs/heads/master` are still advertised as so-called
1590"have" lines. In order to match refs before stripping, add a `^` in front of
1591the ref name. If you combine `!` and `^`, `!` must be specified first.
1592+
1593Even if you hide refs, a client may still be able to steal the target
1594objects via the techniques described in the "SECURITY" section of the
1595linkgit:gitnamespaces[7] man page; it's best to keep private data in a
1596separate repository.
1597
1598transfer.unpackLimit::
1599        When `fetch.unpackLimit` or `receive.unpackLimit` are
1600        not set, the value of this variable is used instead.
1601        The default value is 100.
1602
1603uploadarchive.allowUnreachable::
1604        If true, allow clients to use `git archive --remote` to request
1605        any tree, whether reachable from the ref tips or not. See the
1606        discussion in the "SECURITY" section of
1607        linkgit:git-upload-archive[1] for more details. Defaults to
1608        `false`.
1609
1610uploadpack.hideRefs::
1611        This variable is the same as `transfer.hideRefs`, but applies
1612        only to `upload-pack` (and so affects only fetches, not pushes).
1613        An attempt to fetch a hidden ref by `git fetch` will fail.  See
1614        also `uploadpack.allowTipSHA1InWant`.
1615
1616uploadpack.allowTipSHA1InWant::
1617        When `uploadpack.hideRefs` is in effect, allow `upload-pack`
1618        to accept a fetch request that asks for an object at the tip
1619        of a hidden ref (by default, such a request is rejected).
1620        See also `uploadpack.hideRefs`.  Even if this is false, a client
1621        may be able to steal objects via the techniques described in the
1622        "SECURITY" section of the linkgit:gitnamespaces[7] man page; it's
1623        best to keep private data in a separate repository.
1624
1625uploadpack.allowReachableSHA1InWant::
1626        Allow `upload-pack` to accept a fetch request that asks for an
1627        object that is reachable from any ref tip. However, note that
1628        calculating object reachability is computationally expensive.
1629        Defaults to `false`.  Even if this is false, a client may be able
1630        to steal objects via the techniques described in the "SECURITY"
1631        section of the linkgit:gitnamespaces[7] man page; it's best to
1632        keep private data in a separate repository.
1633
1634uploadpack.allowAnySHA1InWant::
1635        Allow `upload-pack` to accept a fetch request that asks for any
1636        object at all.
1637        Defaults to `false`.
1638
1639uploadpack.keepAlive::
1640        When `upload-pack` has started `pack-objects`, there may be a
1641        quiet period while `pack-objects` prepares the pack. Normally
1642        it would output progress information, but if `--quiet` was used
1643        for the fetch, `pack-objects` will output nothing at all until
1644        the pack data begins. Some clients and networks may consider
1645        the server to be hung and give up. Setting this option instructs
1646        `upload-pack` to send an empty keepalive packet every
1647        `uploadpack.keepAlive` seconds. Setting this option to 0
1648        disables keepalive packets entirely. The default is 5 seconds.
1649
1650uploadpack.packObjectsHook::
1651        If this option is set, when `upload-pack` would run
1652        `git pack-objects` to create a packfile for a client, it will
1653        run this shell command instead.  The `pack-objects` command and
1654        arguments it _would_ have run (including the `git pack-objects`
1655        at the beginning) are appended to the shell command. The stdin
1656        and stdout of the hook are treated as if `pack-objects` itself
1657        was run. I.e., `upload-pack` will feed input intended for
1658        `pack-objects` to the hook, and expects a completed packfile on
1659        stdout.
1660+
1661Note that this configuration variable is ignored if it is seen in the
1662repository-level config (this is a safety measure against fetching from
1663untrusted repositories).
1664
1665uploadpack.allowFilter::
1666        If this option is set, `upload-pack` will support partial
1667        clone and partial fetch object filtering.
1668
1669uploadpack.allowRefInWant::
1670        If this option is set, `upload-pack` will support the `ref-in-want`
1671        feature of the protocol version 2 `fetch` command.  This feature
1672        is intended for the benefit of load-balanced servers which may
1673        not have the same view of what OIDs their refs point to due to
1674        replication delay.
1675
1676url.<base>.insteadOf::
1677        Any URL that starts with this value will be rewritten to
1678        start, instead, with <base>. In cases where some site serves a
1679        large number of repositories, and serves them with multiple
1680        access methods, and some users need to use different access
1681        methods, this feature allows people to specify any of the
1682        equivalent URLs and have Git automatically rewrite the URL to
1683        the best alternative for the particular user, even for a
1684        never-before-seen repository on the site.  When more than one
1685        insteadOf strings match a given URL, the longest match is used.
1686+
1687Note that any protocol restrictions will be applied to the rewritten
1688URL. If the rewrite changes the URL to use a custom protocol or remote
1689helper, you may need to adjust the `protocol.*.allow` config to permit
1690the request.  In particular, protocols you expect to use for submodules
1691must be set to `always` rather than the default of `user`. See the
1692description of `protocol.allow` above.
1693
1694url.<base>.pushInsteadOf::
1695        Any URL that starts with this value will not be pushed to;
1696        instead, it will be rewritten to start with <base>, and the
1697        resulting URL will be pushed to. In cases where some site serves
1698        a large number of repositories, and serves them with multiple
1699        access methods, some of which do not allow push, this feature
1700        allows people to specify a pull-only URL and have Git
1701        automatically use an appropriate URL to push, even for a
1702        never-before-seen repository on the site.  When more than one
1703        pushInsteadOf strings match a given URL, the longest match is
1704        used.  If a remote has an explicit pushurl, Git will ignore this
1705        setting for that remote.
1706
1707user.email::
1708        Your email address to be recorded in any newly created commits.
1709        Can be overridden by the `GIT_AUTHOR_EMAIL`, `GIT_COMMITTER_EMAIL`, and
1710        `EMAIL` environment variables.  See linkgit:git-commit-tree[1].
1711
1712user.name::
1713        Your full name to be recorded in any newly created commits.
1714        Can be overridden by the `GIT_AUTHOR_NAME` and `GIT_COMMITTER_NAME`
1715        environment variables.  See linkgit:git-commit-tree[1].
1716
1717user.useConfigOnly::
1718        Instruct Git to avoid trying to guess defaults for `user.email`
1719        and `user.name`, and instead retrieve the values only from the
1720        configuration. For example, if you have multiple email addresses
1721        and would like to use a different one for each repository, then
1722        with this configuration option set to `true` in the global config
1723        along with a name, Git will prompt you to set up an email before
1724        making new commits in a newly cloned repository.
1725        Defaults to `false`.
1726
1727user.signingKey::
1728        If linkgit:git-tag[1] or linkgit:git-commit[1] is not selecting the
1729        key you want it to automatically when creating a signed tag or
1730        commit, you can override the default selection with this variable.
1731        This option is passed unchanged to gpg's --local-user parameter,
1732        so you may specify a key using any method that gpg supports.
1733
1734versionsort.prereleaseSuffix (deprecated)::
1735        Deprecated alias for `versionsort.suffix`.  Ignored if
1736        `versionsort.suffix` is set.
1737
1738versionsort.suffix::
1739        Even when version sort is used in linkgit:git-tag[1], tagnames
1740        with the same base version but different suffixes are still sorted
1741        lexicographically, resulting e.g. in prerelease tags appearing
1742        after the main release (e.g. "1.0-rc1" after "1.0").  This
1743        variable can be specified to determine the sorting order of tags
1744        with different suffixes.
1745+
1746By specifying a single suffix in this variable, any tagname containing
1747that suffix will appear before the corresponding main release.  E.g. if
1748the variable is set to "-rc", then all "1.0-rcX" tags will appear before
1749"1.0".  If specified multiple times, once per suffix, then the order of
1750suffixes in the configuration will determine the sorting order of tagnames
1751with those suffixes.  E.g. if "-pre" appears before "-rc" in the
1752configuration, then all "1.0-preX" tags will be listed before any
1753"1.0-rcX" tags.  The placement of the main release tag relative to tags
1754with various suffixes can be determined by specifying the empty suffix
1755among those other suffixes.  E.g. if the suffixes "-rc", "", "-ck" and
1756"-bfs" appear in the configuration in this order, then all "v4.8-rcX" tags
1757are listed first, followed by "v4.8", then "v4.8-ckX" and finally
1758"v4.8-bfsX".
1759+
1760If more than one suffixes match the same tagname, then that tagname will
1761be sorted according to the suffix which starts at the earliest position in
1762the tagname.  If more than one different matching suffixes start at
1763that earliest position, then that tagname will be sorted according to the
1764longest of those suffixes.
1765The sorting order between different suffixes is undefined if they are
1766in multiple config files.
1767
1768web.browser::
1769        Specify a web browser that may be used by some commands.
1770        Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
1771        may use it.
1772
1773worktree.guessRemote::
1774        With `add`, if no branch argument, and neither of `-b` nor
1775        `-B` nor `--detach` are given, the command defaults to
1776        creating a new branch from HEAD.  If `worktree.guessRemote` is
1777        set to true, `worktree add` tries to find a remote-tracking
1778        branch whose name uniquely matches the new branch name.  If
1779        such a branch exists, it is checked out and set as "upstream"
1780        for the new branch.  If no such match can be found, it falls
1781        back to creating a new branch from the current HEAD.
