   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.

 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.

 341
 342grep.lineNumber::
 343        If set to true, enable `-n` option by default.
 344
 345grep.column::
 346        If set to true, enable the `--column` option by default.
 347
 348grep.patternType::
 349        Set the default matching behavior. Using a value of 'basic', 'extended',
 350        'fixed', or 'perl' will enable the `--basic-regexp`, `--extended-regexp`,
 351        `--fixed-strings`, or `--perl-regexp` option accordingly, while the
 352        value 'default' will return to the default matching behavior.
 353
 354grep.extendedRegexp::
 355        If set to true, enable `--extended-regexp` option by default. This
 356        option is ignored when the `grep.patternType` option is set to a value
 357        other than 'default'.
 358
 359grep.threads::
 360        Number of grep worker threads to use.
 361        See `grep.threads` in linkgit:git-grep[1] for more information.
 362
 363grep.fallbackToNoIndex::
 364        If set to true, fall back to git grep --no-index if git grep
 365        is executed outside of a git repository.  Defaults to false.
 366
 367gpg.program::
 368        Use this custom program instead of "`gpg`" found on `$PATH` when
 369        making or verifying a PGP signature. The program must support the
 370        same command-line interface as GPG, namely, to verify a detached
 371        signature, "`gpg --verify $file - <$signature`" is run, and the
 372        program is expected to signal a good signature by exiting with
 373        code 0, and to generate an ASCII-armored detached signature, the
 374        standard input of "`gpg -bsau $key`" is fed with the contents to be
 375        signed, and the program is expected to send the result to its
 376        standard output.
 377
 378gpg.format::
 379        Specifies which key format to use when signing with `--gpg-sign`.
 380        Default is "openpgp" and another possible value is "x509".
 381
 382gpg.<format>.program::
 383        Use this to customize the program used for the signing format you
 384        chose. (see `gpg.program` and `gpg.format`) `gpg.program` can still
 385        be used as a legacy synonym for `gpg.openpgp.program`. The default
 386        value for `gpg.x509.program` is "gpgsm".
 387
 388include::gui-config.txt[]
 389
 390guitool.<name>.cmd::
 391        Specifies the shell command line to execute when the corresponding item
 392        of the linkgit:git-gui[1] `Tools` menu is invoked. This option is
 393        mandatory for every tool. The command is executed from the root of
 394        the working directory, and in the environment it receives the name of
 395        the tool as `GIT_GUITOOL`, the name of the currently selected file as
 396        'FILENAME', and the name of the current branch as 'CUR_BRANCH' (if
 397        the head is detached, 'CUR_BRANCH' is empty).
 398
 399guitool.<name>.needsFile::
 400        Run the tool only if a diff is selected in the GUI. It guarantees
 401        that 'FILENAME' is not empty.
 402
 403guitool.<name>.noConsole::
 404        Run the command silently, without creating a window to display its
 405        output.
 406
 407guitool.<name>.noRescan::
 408        Don't rescan the working directory for changes after the tool
 409        finishes execution.
 410
 411guitool.<name>.confirm::
 412        Show a confirmation dialog before actually running the tool.
 413
 414guitool.<name>.argPrompt::
 415        Request a string argument from the user, and pass it to the tool
 416        through the `ARGS` environment variable. Since requesting an
 417        argument implies confirmation, the 'confirm' option has no effect
 418        if this is enabled. If the option is set to 'true', 'yes', or '1',
 419        the dialog uses a built-in generic prompt; otherwise the exact
 420        value of the variable is used.
 421
 422guitool.<name>.revPrompt::
 423        Request a single valid revision from the user, and set the
 424        `REVISION` environment variable. In other aspects this option
 425        is similar to 'argPrompt', and can be used together with it.
 426
 427guitool.<name>.revUnmerged::
 428        Show only unmerged branches in the 'revPrompt' subdialog.
 429        This is useful for tools similar to merge or rebase, but not
 430        for things like checkout or reset.
 431
 432guitool.<name>.title::
 433        Specifies the title to use for the prompt dialog. The default
 434        is the tool name.
 435
 436guitool.<name>.prompt::
 437        Specifies the general prompt string to display at the top of
 438        the dialog, before subsections for 'argPrompt' and 'revPrompt'.
 439        The default value includes the actual command.
 440
 441help.browser::
 442        Specify the browser that will be used to display help in the
 443        'web' format. See linkgit:git-help[1].
 444
 445help.format::
 446        Override the default help format used by linkgit:git-help[1].
 447        Values 'man', 'info', 'web' and 'html' are supported. 'man' is
 448        the default. 'web' and 'html' are the same.
 449
 450help.autoCorrect::
 451        Automatically correct and execute mistyped commands after
 452        waiting for the given number of deciseconds (0.1 sec). If more
 453        than one command can be deduced from the entered text, nothing
 454        will be executed.  If the value of this option is negative,
 455        the corrected command will be executed immediately. If the
 456        value is 0 - the command will be just shown but not executed.
 457        This is the default.
 458
 459help.htmlPath::
 460        Specify the path where the HTML documentation resides. File system paths
 461        and URLs are supported. HTML pages will be prefixed with this path when
 462        help is displayed in the 'web' format. This defaults to the documentation
 463        path of your Git installation.
 464
 465http.proxy::
 466        Override the HTTP proxy, normally configured using the 'http_proxy',
 467        'https_proxy', and 'all_proxy' environment variables (see `curl(1)`). In
 468        addition to the syntax understood by curl, it is possible to specify a
 469        proxy string with a user name but no password, in which case git will
 470        attempt to acquire one in the same way it does for other credentials. See
 471        linkgit:gitcredentials[7] for more information. The syntax thus is
 472        '[protocol://][user[:password]@]proxyhost[:port]'. This can be overridden
 473        on a per-remote basis; see remote.<name>.proxy
 474
 475http.proxyAuthMethod::
 476        Set the method with which to authenticate against the HTTP proxy. This
 477        only takes effect if the configured proxy string contains a user name part
 478        (i.e. is of the form 'user@host' or 'user@host:port'). This can be
 479        overridden on a per-remote basis; see `remote.<name>.proxyAuthMethod`.
 480        Both can be overridden by the `GIT_HTTP_PROXY_AUTHMETHOD` environment
 481        variable.  Possible values are:
 482+
 483--
 484* `anyauth` - Automatically pick a suitable authentication method. It is
 485  assumed that the proxy answers an unauthenticated request with a 407
 486  status code and one or more Proxy-authenticate headers with supported
 487  authentication methods. This is the default.
 488* `basic` - HTTP Basic authentication
 489* `digest` - HTTP Digest authentication; this prevents the password from being
 490  transmitted to the proxy in clear text
 491* `negotiate` - GSS-Negotiate authentication (compare the --negotiate option
 492  of `curl(1)`)
 493* `ntlm` - NTLM authentication (compare the --ntlm option of `curl(1)`)
 494--
 495
 496http.emptyAuth::
 497        Attempt authentication without seeking a username or password.  This
 498        can be used to attempt GSS-Negotiate authentication without specifying
 499        a username in the URL, as libcurl normally requires a username for
 500        authentication.
 501
 502http.delegation::
 503        Control GSSAPI credential delegation. The delegation is disabled
 504        by default in libcurl since version 7.21.7. Set parameter to tell
 505        the server what it is allowed to delegate when it comes to user
 506        credentials. Used with GSS/kerberos. Possible values are:
 507+
 508--
 509* `none` - Don't allow any delegation.
 510* `policy` - Delegates if and only if the OK-AS-DELEGATE flag is set in the
 511  Kerberos service ticket, which is a matter of realm policy.
 512* `always` - Unconditionally allow the server to delegate.
 513--
 514
 515
 516http.extraHeader::
 517        Pass an additional HTTP header when communicating with a server.  If
 518        more than one such entry exists, all of them are added as extra
 519        headers.  To allow overriding the settings inherited from the system
 520        config, an empty value will reset the extra headers to the empty list.
 521
 522http.cookieFile::
 523        The pathname of a file containing previously stored cookie lines,
 524        which should be used
 525        in the Git http session, if they match the server. The file format
 526        of the file to read cookies from should be plain HTTP headers or
 527        the Netscape/Mozilla cookie file format (see `curl(1)`).
 528        NOTE that the file specified with http.cookieFile is used only as
 529        input unless http.saveCookies is set.
 530
 531http.saveCookies::
 532        If set, store cookies received during requests to the file specified by
 533        http.cookieFile. Has no effect if http.cookieFile is unset.
 534
 535http.sslVersion::
 536        The SSL version to use when negotiating an SSL connection, if you
 537        want to force the default.  The available and default version
 538        depend on whether libcurl was built against NSS or OpenSSL and the
 539        particular configuration of the crypto library in use. Internally
 540        this sets the 'CURLOPT_SSL_VERSION' option; see the libcurl
 541        documentation for more details on the format of this option and
 542        for the ssl version supported. Actually the possible values of
 543        this option are:
 544
 545        - sslv2
 546        - sslv3
 547        - tlsv1
 548        - tlsv1.0
 549        - tlsv1.1
 550        - tlsv1.2
 551        - tlsv1.3
 552
 553+
 554Can be overridden by the `GIT_SSL_VERSION` environment variable.
 555To force git to use libcurl's default ssl version and ignore any
 556explicit http.sslversion option, set `GIT_SSL_VERSION` to the
 557empty string.
 558
 559http.sslCipherList::
 560  A list of SSL ciphers to use when negotiating an SSL connection.
 561  The available ciphers depend on whether libcurl was built against
 562  NSS or OpenSSL and the particular configuration of the crypto
 563  library in use.  Internally this sets the 'CURLOPT_SSL_CIPHER_LIST'
 564  option; see the libcurl documentation for more details on the format
 565  of this list.
 566+
 567Can be overridden by the `GIT_SSL_CIPHER_LIST` environment variable.
 568To force git to use libcurl's default cipher list and ignore any
 569explicit http.sslCipherList option, set `GIT_SSL_CIPHER_LIST` to the
 570empty string.
 571
 572http.sslVerify::
 573        Whether to verify the SSL certificate when fetching or pushing
 574        over HTTPS. Defaults to true. Can be overridden by the
 575        `GIT_SSL_NO_VERIFY` environment variable.
 576
 577http.sslCert::
 578        File containing the SSL certificate when fetching or pushing
 579        over HTTPS. Can be overridden by the `GIT_SSL_CERT` environment
 580        variable.
 581
 582http.sslKey::
 583        File containing the SSL private key when fetching or pushing
 584        over HTTPS. Can be overridden by the `GIT_SSL_KEY` environment
 585        variable.
 586
 587http.sslCertPasswordProtected::
 588        Enable Git's password prompt for the SSL certificate.  Otherwise
 589        OpenSSL will prompt the user, possibly many times, if the
 590        certificate or private key is encrypted.  Can be overridden by the
 591        `GIT_SSL_CERT_PASSWORD_PROTECTED` environment variable.
 592
 593http.sslCAInfo::
 594        File containing the certificates to verify the peer with when
 595        fetching or pushing over HTTPS. Can be overridden by the
 596        `GIT_SSL_CAINFO` environment variable.
 597
 598http.sslCAPath::
 599        Path containing files with the CA certificates to verify the peer
 600        with when fetching or pushing over HTTPS. Can be overridden
 601        by the `GIT_SSL_CAPATH` environment variable.
 602
 603http.sslBackend::
 604        Name of the SSL backend to use (e.g. "openssl" or "schannel").
 605        This option is ignored if cURL lacks support for choosing the SSL
 606        backend at runtime.
 607
 608http.schannelCheckRevoke::
 609        Used to enforce or disable certificate revocation checks in cURL
 610        when http.sslBackend is set to "schannel". Defaults to `true` if
 611        unset. Only necessary to disable this if Git consistently errors
 612        and the message is about checking the revocation status of a
 613        certificate. This option is ignored if cURL lacks support for
 614        setting the relevant SSL option at runtime.
 615
 616http.schannelUseSSLCAInfo::
 617        As of cURL v7.60.0, the Secure Channel backend can use the
 618        certificate bundle provided via `http.sslCAInfo`, but that would
 619        override the Windows Certificate Store. Since this is not desirable
 620        by default, Git will tell cURL not to use that bundle by default
 621        when the `schannel` backend was configured via `http.sslBackend`,
 622        unless `http.schannelUseSSLCAInfo` overrides this behavior.
 623
 624http.pinnedpubkey::
 625        Public key of the https service. It may either be the filename of
 626        a PEM or DER encoded public key file or a string starting with
 627        'sha256//' followed by the base64 encoded sha256 hash of the
 628        public key. See also libcurl 'CURLOPT_PINNEDPUBLICKEY'. git will
 629        exit with an error if this option is set but not supported by
 630        cURL.
 631
 632http.sslTry::
 633        Attempt to use AUTH SSL/TLS and encrypted data transfers
 634        when connecting via regular FTP protocol. This might be needed
 635        if the FTP server requires it for security reasons or you wish
 636        to connect securely whenever remote FTP server supports it.
 637        Default is false since it might trigger certificate verification
 638        errors on misconfigured servers.
 639
 640http.maxRequests::
 641        How many HTTP requests to launch in parallel. Can be overridden
 642        by the `GIT_HTTP_MAX_REQUESTS` environment variable. Default is 5.
 643
 644http.minSessions::
 645        The number of curl sessions (counted across slots) to be kept across
 646        requests. They will not be ended with curl_easy_cleanup() until
 647        http_cleanup() is invoked. If USE_CURL_MULTI is not defined, this
 648        value will be capped at 1. Defaults to 1.
 649
 650http.postBuffer::
 651        Maximum size in bytes of the buffer used by smart HTTP
 652        transports when POSTing data to the remote system.
 653        For requests larger than this buffer size, HTTP/1.1 and
 654        Transfer-Encoding: chunked is used to avoid creating a
 655        massive pack file locally.  Default is 1 MiB, which is
 656        sufficient for most requests.
 657
 658http.lowSpeedLimit, http.lowSpeedTime::
 659        If the HTTP transfer speed is less than 'http.lowSpeedLimit'
 660        for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
 661        Can be overridden by the `GIT_HTTP_LOW_SPEED_LIMIT` and
 662        `GIT_HTTP_LOW_SPEED_TIME` environment variables.
 663
 664http.noEPSV::
 665        A boolean which disables using of EPSV ftp command by curl.
 666        This can helpful with some "poor" ftp servers which don't
 667        support EPSV mode. Can be overridden by the `GIT_CURL_FTP_NO_EPSV`
 668        environment variable. Default is false (curl will use EPSV).
 669
 670http.userAgent::
 671        The HTTP USER_AGENT string presented to an HTTP server.  The default
 672        value represents the version of the client Git such as git/1.7.1.
 673        This option allows you to override this value to a more common value
 674        such as Mozilla/4.0.  This may be necessary, for instance, if
 675        connecting through a firewall that restricts HTTP connections to a set
 676        of common USER_AGENT strings (but not including those like git/1.7.1).
 677        Can be overridden by the `GIT_HTTP_USER_AGENT` environment variable.
 678
 679http.followRedirects::
 680        Whether git should follow HTTP redirects. If set to `true`, git
 681        will transparently follow any redirect issued by a server it
 682        encounters. If set to `false`, git will treat all redirects as
 683        errors. If set to `initial`, git will follow redirects only for
 684        the initial request to a remote, but not for subsequent
 685        follow-up HTTP requests. Since git uses the redirected URL as
 686        the base for the follow-up requests, this is generally
 687        sufficient. The default is `initial`.
 688
 689http.<url>.*::
 690        Any of the http.* options above can be applied selectively to some URLs.
 691        For a config key to match a URL, each element of the config key is
 692        compared to that of the URL, in the following order:
 693+
 694--
 695. Scheme (e.g., `https` in `https://example.com/`). This field
 696  must match exactly between the config key and the URL.
 697
 698. Host/domain name (e.g., `example.com` in `https://example.com/`).
 699  This field must match between the config key and the URL. It is
 700  possible to specify a `*` as part of the host name to match all subdomains
 701  at this level. `https://*.example.com/` for example would match
 702  `https://foo.example.com/`, but not `https://foo.bar.example.com/`.
 703
 704. Port number (e.g., `8080` in `http://example.com:8080/`).
 705  This field must match exactly between the config key and the URL.
 706  Omitted port numbers are automatically converted to the correct
 707  default for the scheme before matching.
 708
 709. Path (e.g., `repo.git` in `https://example.com/repo.git`). The
 710  path field of the config key must match the path field of the URL
 711  either exactly or as a prefix of slash-delimited path elements.  This means
 712  a config key with path `foo/` matches URL path `foo/bar`.  A prefix can only
 713  match on a slash (`/`) boundary.  Longer matches take precedence (so a config
 714  key with path `foo/bar` is a better match to URL path `foo/bar` than a config
 715  key with just path `foo/`).
 716
 717. User name (e.g., `user` in `https://user@example.com/repo.git`). If
 718  the config key has a user name it must match the user name in the
 719  URL exactly. If the config key does not have a user name, that
 720  config key will match a URL with any user name (including none),
 721  but at a lower precedence than a config key with a user name.
 722--
 723+
 724The list above is ordered by decreasing precedence; a URL that matches
 725a config key's path is preferred to one that matches its user name. For example,
 726if the URL is `https://user@example.com/foo/bar` a config key match of
 727`https://example.com/foo` will be preferred over a config key match of
 728`https://user@example.com`.
 729+
 730All URLs are normalized before attempting any matching (the password part,
 731if embedded in the URL, is always ignored for matching purposes) so that
 732equivalent URLs that are simply spelled differently will match properly.
 733Environment variable settings always override any matches.  The URLs that are
 734matched against are those given directly to Git commands.  This means any URLs
 735visited as a result of a redirection do not participate in matching.
 736
 737ssh.variant::
 738        By default, Git determines the command line arguments to use
 739        based on the basename of the configured SSH command (configured
 740        using the environment variable `GIT_SSH` or `GIT_SSH_COMMAND` or
 741        the config setting `core.sshCommand`). If the basename is
 742        unrecognized, Git will attempt to detect support of OpenSSH
 743        options by first invoking the configured SSH command with the
 744        `-G` (print configuration) option and will subsequently use
 745        OpenSSH options (if that is successful) or no options besides
 746        the host and remote command (if it fails).
 747+
 748The config variable `ssh.variant` can be set to override this detection.
 749Valid values are `ssh` (to use OpenSSH options), `plink`, `putty`,
 750`tortoiseplink`, `simple` (no options except the host and remote command).
 751The default auto-detection can be explicitly requested using the value
 752`auto`.  Any other value is treated as `ssh`.  This setting can also be
 753overridden via the environment variable `GIT_SSH_VARIANT`.
 754+
 755The current command-line parameters used for each variant are as
 756follows:
 757+
 758--
 759
 760* `ssh` - [-p port] [-4] [-6] [-o option] [username@]host command
 761
 762* `simple` - [username@]host command
 763
 764* `plink` or `putty` - [-P port] [-4] [-6] [username@]host command
 765
 766* `tortoiseplink` - [-P port] [-4] [-6] -batch [username@]host command
 767
 768--
 769+
 770Except for the `simple` variant, command-line parameters are likely to
 771change as git gains new features.
 772
 773i18n.commitEncoding::
 774        Character encoding the commit messages are stored in; Git itself
 775        does not care per se, but this information is necessary e.g. when
 776        importing commits from emails or in the gitk graphical history
 777        browser (and possibly at other places in the future or in other
 778        porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.
 779
 780i18n.logOutputEncoding::
 781        Character encoding the commit messages are converted to when
 782        running 'git log' and friends.
 783
 784imap::
 785        The configuration variables in the 'imap' section are described
 786        in linkgit:git-imap-send[1].
 787
 788index.threads::
 789        Specifies the number of threads to spawn when loading the index.
 790        This is meant to reduce index load time on multiprocessor machines.
 791        Specifying 0 or 'true' will cause Git to auto-detect the number of
 792        CPU's and set the number of threads accordingly. Specifying 1 or
 793        'false' will disable multithreading. Defaults to 'true'.
 794
 795index.version::
 796        Specify the version with which new index files should be
 797        initialized.  This does not affect existing repositories.
 798
 799init.templateDir::
 800        Specify the directory from which templates will be copied.
 801        (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].)
 802
 803instaweb.browser::
 804        Specify the program that will be used to browse your working
 805        repository in gitweb. See linkgit:git-instaweb[1].
 806
 807instaweb.httpd::
 808        The HTTP daemon command-line to start gitweb on your working
 809        repository. See linkgit:git-instaweb[1].
 810
 811instaweb.local::
 812        If true the web server started by linkgit:git-instaweb[1] will
 813        be bound to the local IP (127.0.0.1).
 814
 815instaweb.modulePath::
 816        The default module path for linkgit:git-instaweb[1] to use
 817        instead of /usr/lib/apache2/modules.  Only used if httpd
 818        is Apache.
 819
 820instaweb.port::
 821        The port number to bind the gitweb httpd to. See
 822        linkgit:git-instaweb[1].
 823
 824interactive.singleKey::
 825        In interactive commands, allow the user to provide one-letter
 826        input with a single key (i.e., without hitting enter).
 827        Currently this is used by the `--patch` mode of
 828        linkgit:git-add[1], linkgit:git-checkout[1], linkgit:git-commit[1],
 829        linkgit:git-reset[1], and linkgit:git-stash[1]. Note that this
 830        setting is silently ignored if portable keystroke input
 831        is not available; requires the Perl module Term::ReadKey.
 832
 833interactive.diffFilter::
 834        When an interactive command (such as `git add --patch`) shows
 835        a colorized diff, git will pipe the diff through the shell
 836        command defined by this configuration variable. The command may
 837        mark up the diff further for human consumption, provided that it
 838        retains a one-to-one correspondence with the lines in the
 839        original diff. Defaults to disabled (no filtering).
 840
 841log.abbrevCommit::
 842        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
 843        linkgit:git-whatchanged[1] assume `--abbrev-commit`. You may
 844        override this option with `--no-abbrev-commit`.
 845
 846log.date::
 847        Set the default date-time mode for the 'log' command.
 848        Setting a value for log.date is similar to using 'git log''s
 849        `--date` option.  See linkgit:git-log[1] for details.
 850
 851log.decorate::
 852        Print out the ref names of any commits that are shown by the log
 853        command. If 'short' is specified, the ref name prefixes 'refs/heads/',
 854        'refs/tags/' and 'refs/remotes/' will not be printed. If 'full' is
 855        specified, the full ref name (including prefix) will be printed.
 856        If 'auto' is specified, then if the output is going to a terminal,
 857        the ref names are shown as if 'short' were given, otherwise no ref
 858        names are shown. This is the same as the `--decorate` option
 859        of the `git log`.
 860
 861log.follow::
 862        If `true`, `git log` will act as if the `--follow` option was used when
 863        a single <path> is given.  This has the same limitations as `--follow`,
 864        i.e. it cannot be used to follow multiple files and does not work well
 865        on non-linear history.
 866
 867log.graphColors::
 868        A list of colors, separated by commas, that can be used to draw
 869        history lines in `git log --graph`.
 870
 871log.showRoot::
 872        If true, the initial commit will be shown as a big creation event.
 873        This is equivalent to a diff against an empty tree.
 874        Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
 875        normally hide the root commit will now show it. True by default.
 876
 877log.showSignature::
 878        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
 879        linkgit:git-whatchanged[1] assume `--show-signature`.
 880
 881log.mailmap::
 882        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
 883        linkgit:git-whatchanged[1] assume `--use-mailmap`.
 884
 885mailinfo.scissors::
 886        If true, makes linkgit:git-mailinfo[1] (and therefore
 887        linkgit:git-am[1]) act by default as if the --scissors option
 888        was provided on the command-line. When active, this features
 889        removes everything from the message body before a scissors
 890        line (i.e. consisting mainly of ">8", "8<" and "-").
 891
 892mailmap.file::
 893        The location of an augmenting mailmap file. The default
 894        mailmap, located in the root of the repository, is loaded
 895        first, then the mailmap file pointed to by this variable.
 896        The location of the mailmap file may be in a repository
 897        subdirectory, or somewhere outside of the repository itself.
 898        See linkgit:git-shortlog[1] and linkgit:git-blame[1].
 899
 900mailmap.blob::
 901        Like `mailmap.file`, but consider the value as a reference to a
 902        blob in the repository. If both `mailmap.file` and
 903        `mailmap.blob` are given, both are parsed, with entries from
 904        `mailmap.file` taking precedence. In a bare repository, this
 905        defaults to `HEAD:.mailmap`. In a non-bare repository, it
 906        defaults to empty.
 907
 908man.viewer::
 909        Specify the programs that may be used to display help in the
 910        'man' format. See linkgit:git-help[1].
 911
 912man.<tool>.cmd::
 913        Specify the command to invoke the specified man viewer. The
 914        specified command is evaluated in shell with the man page
 915        passed as argument. (See linkgit:git-help[1].)
 916
 917man.<tool>.path::
 918        Override the path for the given tool that may be used to
 919        display help in the 'man' format. See linkgit:git-help[1].
 920
 921include::merge-config.txt[]
 922
 923mergetool.<tool>.path::
 924        Override the path for the given tool.  This is useful in case
 925        your tool is not in the PATH.
 926
 927mergetool.<tool>.cmd::
 928        Specify the command to invoke the specified merge tool.  The
 929        specified command is evaluated in shell with the following
 930        variables available: 'BASE' is the name of a temporary file
 931        containing the common base of the files to be merged, if available;
 932        'LOCAL' is the name of a temporary file containing the contents of
 933        the file on the current branch; 'REMOTE' is the name of a temporary
 934        file containing the contents of the file from the branch being
 935        merged; 'MERGED' contains the name of the file to which the merge
 936        tool should write the results of a successful merge.
 937
 938mergetool.<tool>.trustExitCode::
 939        For a custom merge command, specify whether the exit code of
 940        the merge command can be used to determine whether the merge was
 941        successful.  If this is not set to true then the merge target file
 942        timestamp is checked and the merge assumed to have been successful
 943        if the file has been updated, otherwise the user is prompted to
 944        indicate the success of the merge.
 945
 946mergetool.meld.hasOutput::
 947        Older versions of `meld` do not support the `--output` option.
 948        Git will attempt to detect whether `meld` supports `--output`
 949        by inspecting the output of `meld --help`.  Configuring
 950        `mergetool.meld.hasOutput` will make Git skip these checks and
 951        use the configured value instead.  Setting `mergetool.meld.hasOutput`
 952        to `true` tells Git to unconditionally use the `--output` option,
 953        and `false` avoids using `--output`.
 954
 955mergetool.keepBackup::
 956        After performing a merge, the original file with conflict markers
 957        can be saved as a file with a `.orig` extension.  If this variable
 958        is set to `false` then this file is not preserved.  Defaults to
 959        `true` (i.e. keep the backup files).
 960
 961mergetool.keepTemporaries::
 962        When invoking a custom merge tool, Git uses a set of temporary
 963        files to pass to the tool. If the tool returns an error and this
 964        variable is set to `true`, then these temporary files will be
 965        preserved, otherwise they will be removed after the tool has
 966        exited. Defaults to `false`.
 967
 968mergetool.writeToTemp::
 969        Git writes temporary 'BASE', 'LOCAL', and 'REMOTE' versions of
 970        conflicting files in the worktree by default.  Git will attempt
 971        to use a temporary directory for these files when set `true`.
 972        Defaults to `false`.
 973
 974mergetool.prompt::
 975        Prompt before each invocation of the merge resolution program.
 976
 977notes.mergeStrategy::
 978        Which merge strategy to choose by default when resolving notes
 979        conflicts.  Must be one of `manual`, `ours`, `theirs`, `union`, or
 980        `cat_sort_uniq`.  Defaults to `manual`.  See "NOTES MERGE STRATEGIES"
 981        section of linkgit:git-notes[1] for more information on each strategy.
 982
 983notes.<name>.mergeStrategy::
 984        Which merge strategy to choose when doing a notes merge into
 985        refs/notes/<name>.  This overrides the more general
 986        "notes.mergeStrategy".  See the "NOTES MERGE STRATEGIES" section in
 987        linkgit:git-notes[1] for more information on the available strategies.
 988
 989notes.displayRef::
 990        The (fully qualified) refname from which to show notes when
 991        showing commit messages.  The value of this variable can be set
 992        to a glob, in which case notes from all matching refs will be
 993        shown.  You may also specify this configuration variable
 994        several times.  A warning will be issued for refs that do not
 995        exist, but a glob that does not match any refs is silently
 996        ignored.
 997+
 998This setting can be overridden with the `GIT_NOTES_DISPLAY_REF`
 999environment variable, which must be a colon separated list of refs or
1000globs.
1001+
1002The effective value of "core.notesRef" (possibly overridden by
1003GIT_NOTES_REF) is also implicitly added to the list of refs to be
1004displayed.
1005
1006notes.rewrite.<command>::
1007        When rewriting commits with <command> (currently `amend` or
1008        `rebase`) and this variable is set to `true`, Git
1009        automatically copies your notes from the original to the
1010        rewritten commit.  Defaults to `true`, but see
1011        "notes.rewriteRef" below.
1012
1013notes.rewriteMode::
1014        When copying notes during a rewrite (see the
1015        "notes.rewrite.<command>" option), determines what to do if
1016        the target commit already has a note.  Must be one of
1017        `overwrite`, `concatenate`, `cat_sort_uniq`, or `ignore`.
1018        Defaults to `concatenate`.
1019+
1020This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
1021environment variable.
1022
1023notes.rewriteRef::
1024        When copying notes during a rewrite, specifies the (fully
1025        qualified) ref whose notes should be copied.  The ref may be a
1026        glob, in which case notes in all matching refs will be copied.
1027        You may also specify this configuration several times.
1028+
1029Does not have a default value; you must configure this variable to
1030enable note rewriting.  Set it to `refs/notes/commits` to enable
1031rewriting for the default commit notes.
1032+
1033This setting can be overridden with the `GIT_NOTES_REWRITE_REF`
1034environment variable, which must be a colon separated list of refs or
1035globs.
1036
1037pack.window::
1038        The size of the window used by linkgit:git-pack-objects[1] when no
1039        window size is given on the command line. Defaults to 10.
1040
1041pack.depth::
1042        The maximum delta depth used by linkgit:git-pack-objects[1] when no
1043        maximum depth is given on the command line. Defaults to 50.
1044        Maximum value is 4095.
1045
1046pack.windowMemory::
1047        The maximum size of memory that is consumed by each thread
1048        in linkgit:git-pack-objects[1] for pack window memory when
1049        no limit is given on the command line.  The value can be
1050        suffixed with "k", "m", or "g".  When left unconfigured (or
1051        set explicitly to 0), there will be no limit.
1052
1053pack.compression::
1054        An integer -1..9, indicating the compression level for objects
1055        in a pack file. -1 is the zlib default. 0 means no
1056        compression, and 1..9 are various speed/size tradeoffs, 9 being
1057        slowest.  If not set,  defaults to core.compression.  If that is
1058        not set,  defaults to -1, the zlib default, which is "a default
1059        compromise between speed and compression (currently equivalent
1060        to level 6)."
1061+
1062Note that changing the compression level will not automatically recompress
1063all existing objects. You can force recompression by passing the -F option
1064to linkgit:git-repack[1].
1065
1066pack.island::
1067        An extended regular expression configuring a set of delta
1068        islands. See "DELTA ISLANDS" in linkgit:git-pack-objects[1]
1069        for details.
1070
1071pack.islandCore::
1072        Specify an island name which gets to have its objects be
1073        packed first. This creates a kind of pseudo-pack at the front
1074        of one pack, so that the objects from the specified island are
1075        hopefully faster to copy into any pack that should be served
1076        to a user requesting these objects. In practice this means
1077        that the island specified should likely correspond to what is
1078        the most commonly cloned in the repo. See also "DELTA ISLANDS"
1079        in linkgit:git-pack-objects[1].
1080
1081pack.deltaCacheSize::
1082        The maximum memory in bytes used for caching deltas in
1083        linkgit:git-pack-objects[1] before writing them out to a pack.
1084        This cache is used to speed up the writing object phase by not
1085        having to recompute the final delta result once the best match
1086        for all objects is found.  Repacking large repositories on machines
1087        which are tight with memory might be badly impacted by this though,
1088        especially if this cache pushes the system into swapping.
1089        A value of 0 means no limit. The smallest size of 1 byte may be
1090        used to virtually disable this cache. Defaults to 256 MiB.
1091
1092pack.deltaCacheLimit::
1093        The maximum size of a delta, that is cached in
1094        linkgit:git-pack-objects[1]. This cache is used to speed up the
1095        writing object phase by not having to recompute the final delta
1096        result once the best match for all objects is found.
1097        Defaults to 1000. Maximum value is 65535.
1098
1099pack.threads::
1100        Specifies the number of threads to spawn when searching for best
1101        delta matches.  This requires that linkgit:git-pack-objects[1]
1102        be compiled with pthreads otherwise this option is ignored with a
1103        warning. This is meant to reduce packing time on multiprocessor
1104        machines. The required amount of memory for the delta search window
1105        is however multiplied by the number of threads.
1106        Specifying 0 will cause Git to auto-detect the number of CPU's
1107        and set the number of threads accordingly.
1108
1109pack.indexVersion::
1110        Specify the default pack index version.  Valid values are 1 for
1111        legacy pack index used by Git versions prior to 1.5.2, and 2 for
1112        the new pack index with capabilities for packs larger than 4 GB
1113        as well as proper protection against the repacking of corrupted
1114        packs.  Version 2 is the default.  Note that version 2 is enforced
1115        and this config option ignored whenever the corresponding pack is
1116        larger than 2 GB.
1117+
1118If you have an old Git that does not understand the version 2 `*.idx` file,
1119cloning or fetching over a non native protocol (e.g. "http")
1120that will copy both `*.pack` file and corresponding `*.idx` file from the
1121other side may give you a repository that cannot be accessed with your
1122older version of Git. If the `*.pack` file is smaller than 2 GB, however,
1123you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
1124the `*.idx` file.
1125
1126pack.packSizeLimit::
1127        The maximum size of a pack.  This setting only affects
1128        packing to a file when repacking, i.e. the git:// protocol
1129        is unaffected.  It can be overridden by the `--max-pack-size`
1130        option of linkgit:git-repack[1].  Reaching this limit results
1131        in the creation of multiple packfiles; which in turn prevents
1132        bitmaps from being created.
1133        The minimum size allowed is limited to 1 MiB.
1134        The default is unlimited.
1135        Common unit suffixes of 'k', 'm', or 'g' are
1136        supported.
1137
1138pack.useBitmaps::
1139        When true, git will use pack bitmaps (if available) when packing
1140        to stdout (e.g., during the server side of a fetch). Defaults to
1141        true. You should not generally need to turn this off unless
1142        you are debugging pack bitmaps.
1143
1144pack.writeBitmaps (deprecated)::
1145        This is a deprecated synonym for `repack.writeBitmaps`.
1146
1147pack.writeBitmapHashCache::
1148        When true, git will include a "hash cache" section in the bitmap
1149        index (if one is written). This cache can be used to feed git's
1150        delta heuristics, potentially leading to better deltas between
1151        bitmapped and non-bitmapped objects (e.g., when serving a fetch
1152        between an older, bitmapped pack and objects that have been
1153        pushed since the last gc). The downside is that it consumes 4
1154        bytes per object of disk space, and that JGit's bitmap
1155        implementation does not understand it, causing it to complain if
1156        Git and JGit are used on the same repository. Defaults to false.
1157
1158pager.<cmd>::
1159        If the value is boolean, turns on or off pagination of the
1160        output of a particular Git subcommand when writing to a tty.
1161        Otherwise, turns on pagination for the subcommand using the
1162        pager specified by the value of `pager.<cmd>`.  If `--paginate`
1163        or `--no-pager` is specified on the command line, it takes
1164        precedence over this option.  To disable pagination for all
1165        commands, set `core.pager` or `GIT_PAGER` to `cat`.
1166
1167pretty.<name>::
1168        Alias for a --pretty= format string, as specified in
1169        linkgit:git-log[1]. Any aliases defined here can be used just
1170        as the built-in pretty formats could. For example,
1171        running `git config pretty.changelog "format:* %H %s"`
1172        would cause the invocation `git log --pretty=changelog`
1173        to be equivalent to running `git log "--pretty=format:* %H %s"`.
1174        Note that an alias with the same name as a built-in format
1175        will be silently ignored.
1176
1177protocol.allow::
1178        If set, provide a user defined default policy for all protocols which
1179        don't explicitly have a policy (`protocol.<name>.allow`).  By default,
1180        if unset, known-safe protocols (http, https, git, ssh, file) have a
1181        default policy of `always`, known-dangerous protocols (ext) have a
1182        default policy of `never`, and all other protocols have a default
1183        policy of `user`.  Supported policies:
1184+
1185--
1186
1187* `always` - protocol is always able to be used.
1188
1189* `never` - protocol is never able to be used.
1190
1191* `user` - protocol is only able to be used when `GIT_PROTOCOL_FROM_USER` is
1192  either unset or has a value of 1.  This policy should be used when you want a
1193  protocol to be directly usable by the user but don't want it used by commands which
1194  execute clone/fetch/push commands without user input, e.g. recursive
1195  submodule initialization.
1196
1197--
1198
1199protocol.<name>.allow::
1200        Set a policy to be used by protocol `<name>` with clone/fetch/push
1201        commands. See `protocol.allow` above for the available policies.
1202+
1203The protocol names currently used by git are:
1204+
1205--
1206  - `file`: any local file-based path (including `file://` URLs,
1207    or local paths)
1208
1209  - `git`: the anonymous git protocol over a direct TCP
1210    connection (or proxy, if configured)
1211
1212  - `ssh`: git over ssh (including `host:path` syntax,
1213    `ssh://`, etc).
1214
1215  - `http`: git over http, both "smart http" and "dumb http".
1216    Note that this does _not_ include `https`; if you want to configure
1217    both, you must do so individually.
1218
1219  - any external helpers are named by their protocol (e.g., use
1220    `hg` to allow the `git-remote-hg` helper)
1221--
1222
1223protocol.version::
1224        Experimental. If set, clients will attempt to communicate with a
1225        server using the specified protocol version.  If unset, no
1226        attempt will be made by the client to communicate using a
1227        particular protocol version, this results in protocol version 0
1228        being used.
1229        Supported versions:
1230+
1231--
1232
1233* `0` - the original wire protocol.
1234
1235* `1` - the original wire protocol with the addition of a version string
1236  in the initial response from the server.
1237
1238* `2` - link:technical/protocol-v2.html[wire protocol version 2].

1253        `branch.<name>.pushRemote` for specific branches.
1254
1255remote.<name>.url::
1256        The URL of a remote repository.  See linkgit:git-fetch[1] or
1257        linkgit:git-push[1].
1258
1259remote.<name>.pushurl::
1260        The push URL of a remote repository.  See linkgit:git-push[1].
1261
1262remote.<name>.proxy::
1263        For remotes that require curl (http, https and ftp), the URL to
1264        the proxy to use for that remote.  Set to the empty string to
1265        disable proxying for that remote.
1266
1267remote.<name>.proxyAuthMethod::
1268        For remotes that require curl (http, https and ftp), the method to use for
1269        authenticating against the proxy in use (probably set in
1270        `remote.<name>.proxy`). See `http.proxyAuthMethod`.
1271
1272remote.<name>.fetch::
1273        The default set of "refspec" for linkgit:git-fetch[1]. See
1274        linkgit:git-fetch[1].
1275
1276remote.<name>.push::
1277        The default set of "refspec" for linkgit:git-push[1]. See
1278        linkgit:git-push[1].
1279
1280remote.<name>.mirror::
1281        If true, pushing to this remote will automatically behave
1282        as if the `--mirror` option was given on the command line.
1283
1284remote.<name>.skipDefaultUpdate::
1285        If true, this remote will be skipped by default when updating
1286        using linkgit:git-fetch[1] or the `update` subcommand of
1287        linkgit:git-remote[1].
1288
1289remote.<name>.skipFetchAll::
1290        If true, this remote will be skipped by default when updating
1291        using linkgit:git-fetch[1] or the `update` subcommand of
1292        linkgit:git-remote[1].
1293
1294remote.<name>.receivepack::
1295        The default program to execute on the remote side when pushing.  See
1296        option --receive-pack of linkgit:git-push[1].
1297
1298remote.<name>.uploadpack::
1299        The default program to execute on the remote side when fetching.  See
1300        option --upload-pack of linkgit:git-fetch-pack[1].
1301
1302remote.<name>.tagOpt::
1303        Setting this value to --no-tags disables automatic tag following when
1304        fetching from remote <name>. Setting it to --tags will fetch every
1305        tag from remote <name>, even if they are not reachable from remote
1306        branch heads. Passing these flags directly to linkgit:git-fetch[1] can
1307        override this setting. See options --tags and --no-tags of
1308        linkgit:git-fetch[1].
1309
1310remote.<name>.vcs::
1311        Setting this to a value <vcs> will cause Git to interact with
1312        the remote with the git-remote-<vcs> helper.
1313
1314remote.<name>.prune::
1315        When set to true, fetching from this remote by default will also
1316        remove any remote-tracking references that no longer exist on the
1317        remote (as if the `--prune` option was given on the command line).
1318        Overrides `fetch.prune` settings, if any.
1319
1320remote.<name>.pruneTags::
1321        When set to true, fetching from this remote by default will also
1322        remove any local tags that no longer exist on the remote if pruning
1323        is activated in general via `remote.<name>.prune`, `fetch.prune` or
1324        `--prune`. Overrides `fetch.pruneTags` settings, if any.
1325+
1326See also `remote.<name>.prune` and the PRUNING section of
1327linkgit:git-fetch[1].
1328
1329remotes.<group>::
1330        The list of remotes which are fetched by "git remote update
1331        <group>".  See linkgit:git-remote[1].
1332
1333repack.useDeltaBaseOffset::
1334        By default, linkgit:git-repack[1] creates packs that use
1335        delta-base offset. If you need to share your repository with
1336        Git older than version 1.4.4, either directly or via a dumb
1337        protocol such as http, then you need to set this option to
1338        "false" and repack. Access from old Git versions over the
1339        native protocol are unaffected by this option.
1340
1341repack.packKeptObjects::
1342        If set to true, makes `git repack` act as if
1343        `--pack-kept-objects` was passed. See linkgit:git-repack[1] for
1344        details. Defaults to `false` normally, but `true` if a bitmap
1345        index is being written (either via `--write-bitmap-index` or
1346        `repack.writeBitmaps`).
1347
1348repack.useDeltaIslands::
1349        If set to true, makes `git repack` act as if `--delta-islands`
1350        was passed. Defaults to `false`.
1351
1352repack.writeBitmaps::
1353        When true, git will write a bitmap index when packing all
1354        objects to disk (e.g., when `git repack -a` is run).  This
1355        index can speed up the "counting objects" phase of subsequent
1356        packs created for clones and fetches, at the cost of some disk
1357        space and extra time spent on the initial repack.  This has
1358        no effect if multiple packfiles are created.
1359        Defaults to false.
1360
1361rerere.autoUpdate::
1362        When set to true, `git-rerere` updates the index with the
1363        resulting contents after it cleanly resolves conflicts using
1364        previously recorded resolution.  Defaults to false.
1365
1366rerere.enabled::
1367        Activate recording of resolved conflicts, so that identical
1368        conflict hunks can be resolved automatically, should they be
1369        encountered again.  By default, linkgit:git-rerere[1] is
1370        enabled if there is an `rr-cache` directory under the
1371        `$GIT_DIR`, e.g. if "rerere" was previously used in the
1372        repository.
1373
1374reset.quiet::
1375        When set to true, 'git reset' will default to the '--quiet' option.
1376
1377include::sendemail-config.txt[]
1378
1379sequence.editor::
1380        Text editor used by `git rebase -i` for editing the rebase instruction file.
1381        The value is meant to be interpreted by the shell when it is used.
1382        It can be overridden by the `GIT_SEQUENCE_EDITOR` environment variable.
1383        When not configured the default commit message editor is used instead.
1384
1385showBranch.default::
1386        The default set of branches for linkgit:git-show-branch[1].
1387        See linkgit:git-show-branch[1].
1388
1389splitIndex.maxPercentChange::
1390        When the split index feature is used, this specifies the
1391        percent of entries the split index can contain compared to the
1392        total number of entries in both the split index and the shared
1393        index before a new shared index is written.
1394        The value should be between 0 and 100. If the value is 0 then
1395        a new shared index is always written, if it is 100 a new
1396        shared index is never written.
1397        By default the value is 20, so a new shared index is written
1398        if the number of entries in the split index would be greater
1399        than 20 percent of the total number of entries.
1400        See linkgit:git-update-index[1].
1401
1402splitIndex.sharedIndexExpire::
1403        When the split index feature is used, shared index files that
1404        were not modified since the time this variable specifies will
1405        be removed when a new shared index file is created. The value
1406        "now" expires all entries immediately, and "never" suppresses
1407        expiration altogether.
1408        The default value is "2.weeks.ago".
1409        Note that a shared index file is considered modified (for the
1410        purpose of expiration) each time a new split-index file is
1411        either created based on it or read from it.
1412        See linkgit:git-update-index[1].
1413
1414status.relativePaths::
1415        By default, linkgit:git-status[1] shows paths relative to the
1416        current directory. Setting this variable to `false` shows paths
1417        relative to the repository root (this was the default for Git
1418        prior to v1.5.4).
1419
1420status.short::
1421        Set to true to enable --short by default in linkgit:git-status[1].
1422        The option --no-short takes precedence over this variable.
1423
1424status.branch::
1425        Set to true to enable --branch by default in linkgit:git-status[1].
1426        The option --no-branch takes precedence over this variable.
1427
1428status.displayCommentPrefix::
1429        If set to true, linkgit:git-status[1] will insert a comment
1430        prefix before each output line (starting with
1431        `core.commentChar`, i.e. `#` by default). This was the
1432        behavior of linkgit:git-status[1] in Git 1.8.4 and previous.
1433        Defaults to false.
1434
1435status.renameLimit::
1436        The number of files to consider when performing rename detection
1437        in linkgit:git-status[1] and linkgit:git-commit[1]. Defaults to
1438        the value of diff.renameLimit.
1439
1440status.renames::
1441        Whether and how Git detects renames in linkgit:git-status[1] and
1442        linkgit:git-commit[1] .  If set to "false", rename detection is
1443        disabled. If set to "true", basic rename detection is enabled.
1444        If set to "copies" or "copy", Git will detect copies, as well.
1445        Defaults to the value of diff.renames.
1446
1447status.showStash::
1448        If set to true, linkgit:git-status[1] will display the number of
1449        entries currently stashed away.
1450        Defaults to false.
1451
1452status.showUntrackedFiles::
1453        By default, linkgit:git-status[1] and linkgit:git-commit[1] show
1454        files which are not currently tracked by Git. Directories which
1455        contain only untracked files, are shown with the directory name
1456        only. Showing untracked files means that Git needs to lstat() all
1457        the files in the whole repository, which might be slow on some
1458        systems. So, this variable controls how the commands displays
1459        the untracked files. Possible values are:
1460+
1461--
1462* `no` - Show no untracked files.
1463* `normal` - Show untracked files and directories.
1464* `all` - Show also individual files in untracked directories.
1465--
1466+
1467If this variable is not specified, it defaults to 'normal'.
1468This variable can be overridden with the -u|--untracked-files option
1469of linkgit:git-status[1] and linkgit:git-commit[1].
1470
1471status.submoduleSummary::
1472        Defaults to false.
1473        If this is set to a non zero number or true (identical to -1 or an
1474        unlimited number), the submodule summary will be enabled and a
1475        summary of commits for modified submodules will be shown (see
1476        --summary-limit option of linkgit:git-submodule[1]). Please note
1477        that the summary output command will be suppressed for all
1478        submodules when `diff.ignoreSubmodules` is set to 'all' or only
1479        for those submodules where `submodule.<name>.ignore=all`. The only
1480        exception to that rule is that status and commit will show staged
1481        submodule changes. To
1482        also view the summary for ignored submodules you can either use
1483        the --ignore-submodules=dirty command-line option or the 'git
1484        submodule summary' command, which shows a similar output but does
1485        not honor these settings.
1486
1487stash.showPatch::
1488        If this is set to true, the `git stash show` command without an
1489        option will show the stash entry in patch form.  Defaults to false.
1490        See description of 'show' command in linkgit:git-stash[1].
1491
1492stash.showStat::
1493        If this is set to true, the `git stash show` command without an
1494        option will show diffstat of the stash entry.  Defaults to true.
1495        See description of 'show' command in linkgit:git-stash[1].
1496
1497include::submodule-config.txt[]
1498
1499tag.forceSignAnnotated::
1500        A boolean to specify whether annotated tags created should be GPG signed.
1501        If `--annotate` is specified on the command line, it takes
1502        precedence over this option.
1503
1504tag.sort::
1505        This variable controls the sort ordering of tags when displayed by
1506        linkgit:git-tag[1]. Without the "--sort=<value>" option provided, the
1507        value of this variable will be used as the default.
1508
1509tar.umask::
1510        This variable can be used to restrict the permission bits of
1511        tar archive entries.  The default is 0002, which turns off the
1512        world write bit.  The special value "user" indicates that the
1513        archiving user's umask will be used instead.  See umask(2) and
1514        linkgit:git-archive[1].
1515
1516transfer.fsckObjects::
1517        When `fetch.fsckObjects` or `receive.fsckObjects` are
1518        not set, the value of this variable is used instead.
1519        Defaults to false.
1520+
1521When set, the fetch or receive will abort in the case of a malformed
1522object or a link to a nonexistent object. In addition, various other
1523issues are checked for, including legacy issues (see `fsck.<msg-id>`),
1524and potential security issues like the existence of a `.GIT` directory
1525or a malicious `.gitmodules` file (see the release notes for v2.2.1
1526and v2.17.1 for details). Other sanity and security checks may be
1527added in future releases.
1528+
1529On the receiving side, failing fsckObjects will make those objects
1530unreachable, see "QUARANTINE ENVIRONMENT" in
1531linkgit:git-receive-pack[1]. On the fetch side, malformed objects will
1532instead be left unreferenced in the repository.
1533+
1534Due to the non-quarantine nature of the `fetch.fsckObjects`
1535implementation it can not be relied upon to leave the object store
1536clean like `receive.fsckObjects` can.
1537+
1538As objects are unpacked they're written to the object store, so there
1539can be cases where malicious objects get introduced even though the
1540"fetch" failed, only to have a subsequent "fetch" succeed because only
1541new incoming objects are checked, not those that have already been
1542written to the object store. That difference in behavior should not be
1543relied upon. In the future, such objects may be quarantined for
1544"fetch" as well.
1545+
1546For now, the paranoid need to find some way to emulate the quarantine
1547environment if they'd like the same protection as "push". E.g. in the
1548case of an internal mirror do the mirroring in two steps, one to fetch
1549the untrusted objects, and then do a second "push" (which will use the
1550quarantine) to another internal repo, and have internal clients
1551consume this pushed-to repository, or embargo internal fetches and
1552only allow them once a full "fsck" has run (and no new fetches have
1553happened in the meantime).
1554
1555transfer.hideRefs::
1556        String(s) `receive-pack` and `upload-pack` use to decide which
1557        refs to omit from their initial advertisements.  Use more than
1558        one definition to specify multiple prefix strings. A ref that is
1559        under the hierarchies listed in the value of this variable is
1560        excluded, and is hidden when responding to `git push` or `git
1561        fetch`.  See `receive.hideRefs` and `uploadpack.hideRefs` for
1562        program-specific versions of this config.
1563+
1564You may also include a `!` in front of the ref name to negate the entry,
1565explicitly exposing it, even if an earlier entry marked it as hidden.
1566If you have multiple hideRefs values, later entries override earlier ones
1567(and entries in more-specific config files override less-specific ones).
1568+
1569If a namespace is in use, the namespace prefix is stripped from each
1570reference before it is matched against `transfer.hiderefs` patterns.
1571For example, if `refs/heads/master` is specified in `transfer.hideRefs` and
1572the current namespace is `foo`, then `refs/namespaces/foo/refs/heads/master`
1573is omitted from the advertisements but `refs/heads/master` and
1574`refs/namespaces/bar/refs/heads/master` are still advertised as so-called
1575"have" lines. In order to match refs before stripping, add a `^` in front of
1576the ref name. If you combine `!` and `^`, `!` must be specified first.
1577+
1578Even if you hide refs, a client may still be able to steal the target
1579objects via the techniques described in the "SECURITY" section of the
1580linkgit:gitnamespaces[7] man page; it's best to keep private data in a
1581separate repository.
1582
1583transfer.unpackLimit::
1584        When `fetch.unpackLimit` or `receive.unpackLimit` are
1585        not set, the value of this variable is used instead.
1586        The default value is 100.
1587
1588uploadarchive.allowUnreachable::
1589        If true, allow clients to use `git archive --remote` to request
1590        any tree, whether reachable from the ref tips or not. See the
1591        discussion in the "SECURITY" section of
1592        linkgit:git-upload-archive[1] for more details. Defaults to
1593        `false`.
1594
1595uploadpack.hideRefs::
1596        This variable is the same as `transfer.hideRefs`, but applies
1597        only to `upload-pack` (and so affects only fetches, not pushes).
1598        An attempt to fetch a hidden ref by `git fetch` will fail.  See
1599        also `uploadpack.allowTipSHA1InWant`.
1600
1601uploadpack.allowTipSHA1InWant::
1602        When `uploadpack.hideRefs` is in effect, allow `upload-pack`
1603        to accept a fetch request that asks for an object at the tip
1604        of a hidden ref (by default, such a request is rejected).
1605        See also `uploadpack.hideRefs`.  Even if this is false, a client
1606        may be able to steal objects via the techniques described in the
1607        "SECURITY" section of the linkgit:gitnamespaces[7] man page; it's
1608        best to keep private data in a separate repository.
1609
1610uploadpack.allowReachableSHA1InWant::
1611        Allow `upload-pack` to accept a fetch request that asks for an
1612        object that is reachable from any ref tip. However, note that
1613        calculating object reachability is computationally expensive.
1614        Defaults to `false`.  Even if this is false, a client may be able
1615        to steal objects via the techniques described in the "SECURITY"
1616        section of the linkgit:gitnamespaces[7] man page; it's best to
1617        keep private data in a separate repository.
1618
1619uploadpack.allowAnySHA1InWant::
1620        Allow `upload-pack` to accept a fetch request that asks for any
1621        object at all.
1622        Defaults to `false`.
1623
1624uploadpack.keepAlive::
1625        When `upload-pack` has started `pack-objects`, there may be a
1626        quiet period while `pack-objects` prepares the pack. Normally
1627        it would output progress information, but if `--quiet` was used
1628        for the fetch, `pack-objects` will output nothing at all until
1629        the pack data begins. Some clients and networks may consider
1630        the server to be hung and give up. Setting this option instructs
1631        `upload-pack` to send an empty keepalive packet every
1632        `uploadpack.keepAlive` seconds. Setting this option to 0
1633        disables keepalive packets entirely. The default is 5 seconds.
1634
1635uploadpack.packObjectsHook::
1636        If this option is set, when `upload-pack` would run
1637        `git pack-objects` to create a packfile for a client, it will
1638        run this shell command instead.  The `pack-objects` command and
1639        arguments it _would_ have run (including the `git pack-objects`
1640        at the beginning) are appended to the shell command. The stdin
1641        and stdout of the hook are treated as if `pack-objects` itself
1642        was run. I.e., `upload-pack` will feed input intended for
1643        `pack-objects` to the hook, and expects a completed packfile on
1644        stdout.
1645+
1646Note that this configuration variable is ignored if it is seen in the
1647repository-level config (this is a safety measure against fetching from
1648untrusted repositories).
1649
1650uploadpack.allowFilter::
1651        If this option is set, `upload-pack` will support partial
1652        clone and partial fetch object filtering.
1653
1654uploadpack.allowRefInWant::
1655        If this option is set, `upload-pack` will support the `ref-in-want`
1656        feature of the protocol version 2 `fetch` command.  This feature
1657        is intended for the benefit of load-balanced servers which may
1658        not have the same view of what OIDs their refs point to due to
1659        replication delay.
1660
1661url.<base>.insteadOf::
1662        Any URL that starts with this value will be rewritten to
1663        start, instead, with <base>. In cases where some site serves a
1664        large number of repositories, and serves them with multiple
1665        access methods, and some users need to use different access
1666        methods, this feature allows people to specify any of the
1667        equivalent URLs and have Git automatically rewrite the URL to
1668        the best alternative for the particular user, even for a
1669        never-before-seen repository on the site.  When more than one
1670        insteadOf strings match a given URL, the longest match is used.
1671+
1672Note that any protocol restrictions will be applied to the rewritten
1673URL. If the rewrite changes the URL to use a custom protocol or remote
1674helper, you may need to adjust the `protocol.*.allow` config to permit
1675the request.  In particular, protocols you expect to use for submodules
1676must be set to `always` rather than the default of `user`. See the
1677description of `protocol.allow` above.
1678
1679url.<base>.pushInsteadOf::
1680        Any URL that starts with this value will not be pushed to;
1681        instead, it will be rewritten to start with <base>, and the
1682        resulting URL will be pushed to. In cases where some site serves
1683        a large number of repositories, and serves them with multiple
1684        access methods, some of which do not allow push, this feature
1685        allows people to specify a pull-only URL and have Git
1686        automatically use an appropriate URL to push, even for a
1687        never-before-seen repository on the site.  When more than one
1688        pushInsteadOf strings match a given URL, the longest match is
1689        used.  If a remote has an explicit pushurl, Git will ignore this
1690        setting for that remote.
1691
1692user.email::
1693        Your email address to be recorded in any newly created commits.
1694        Can be overridden by the `GIT_AUTHOR_EMAIL`, `GIT_COMMITTER_EMAIL`, and
1695        `EMAIL` environment variables.  See linkgit:git-commit-tree[1].
1696
1697user.name::
1698        Your full name to be recorded in any newly created commits.
1699        Can be overridden by the `GIT_AUTHOR_NAME` and `GIT_COMMITTER_NAME`
1700        environment variables.  See linkgit:git-commit-tree[1].
1701
1702user.useConfigOnly::
1703        Instruct Git to avoid trying to guess defaults for `user.email`
1704        and `user.name`, and instead retrieve the values only from the
1705        configuration. For example, if you have multiple email addresses
1706        and would like to use a different one for each repository, then
1707        with this configuration option set to `true` in the global config
1708        along with a name, Git will prompt you to set up an email before
1709        making new commits in a newly cloned repository.
1710        Defaults to `false`.
1711
1712user.signingKey::
1713        If linkgit:git-tag[1] or linkgit:git-commit[1] is not selecting the
1714        key you want it to automatically when creating a signed tag or
1715        commit, you can override the default selection with this variable.
1716        This option is passed unchanged to gpg's --local-user parameter,
1717        so you may specify a key using any method that gpg supports.
1718
1719versionsort.prereleaseSuffix (deprecated)::
1720        Deprecated alias for `versionsort.suffix`.  Ignored if
1721        `versionsort.suffix` is set.
1722
1723versionsort.suffix::
1724        Even when version sort is used in linkgit:git-tag[1], tagnames
1725        with the same base version but different suffixes are still sorted
1726        lexicographically, resulting e.g. in prerelease tags appearing
1727        after the main release (e.g. "1.0-rc1" after "1.0").  This
1728        variable can be specified to determine the sorting order of tags
1729        with different suffixes.
1730+
1731By specifying a single suffix in this variable, any tagname containing
1732that suffix will appear before the corresponding main release.  E.g. if
1733the variable is set to "-rc", then all "1.0-rcX" tags will appear before
1734"1.0".  If specified multiple times, once per suffix, then the order of
1735suffixes in the configuration will determine the sorting order of tagnames
1736with those suffixes.  E.g. if "-pre" appears before "-rc" in the
1737configuration, then all "1.0-preX" tags will be listed before any
1738"1.0-rcX" tags.  The placement of the main release tag relative to tags
1739with various suffixes can be determined by specifying the empty suffix
1740among those other suffixes.  E.g. if the suffixes "-rc", "", "-ck" and
1741"-bfs" appear in the configuration in this order, then all "v4.8-rcX" tags
1742are listed first, followed by "v4.8", then "v4.8-ckX" and finally
1743"v4.8-bfsX".
1744+
1745If more than one suffixes match the same tagname, then that tagname will
1746be sorted according to the suffix which starts at the earliest position in
1747the tagname.  If more than one different matching suffixes start at
1748that earliest position, then that tagname will be sorted according to the
1749longest of those suffixes.
1750The sorting order between different suffixes is undefined if they are
1751in multiple config files.
1752
1753web.browser::
1754        Specify a web browser that may be used by some commands.
1755        Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
1756        may use it.
1757
1758worktree.guessRemote::
1759        With `add`, if no branch argument, and neither of `-b` nor
1760        `-B` nor `--detach` are given, the command defaults to
1761        creating a new branch from HEAD.  If `worktree.guessRemote` is
1762        set to true, `worktree add` tries to find a remote-tracking
1763        branch whose name uniquely matches the new branch name.  If
1764        such a branch exists, it is checked out and set as "upstream"
1765        for the new branch.  If no such match can be found, it falls
1766        back to creating a new branch from the current HEAD.
