Documentation / config.txton commit build: reconfigure automatically if configure.ac changes (8242ff4)
   1CONFIGURATION FILE
   2------------------
   3
   4The git configuration file contains a number of variables that affect
   5the git command's 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.
  18
  19Syntax
  20~~~~~~
  21
  22The syntax is fairly flexible and permissive; whitespaces are mostly
  23ignored.  The '#' and ';' characters begin comments to the end of line,
  24blank lines are ignored.
  25
  26The file consists of sections and variables.  A section begins with
  27the name of the section in square brackets and continues until the next
  28section begins.  Section names are not case sensitive.  Only alphanumeric
  29characters, `-` and `.` are allowed in section names.  Each variable
  30must belong to some section, which means that there must be a section
  31header before the first setting of a variable.
  32
  33Sections can be further divided into subsections.  To begin a subsection
  34put its name in double quotes, separated by space from the section name,
  35in the section header, like in the example below:
  36
  37--------
  38        [section "subsection"]
  39
  40--------
  41
  42Subsection names are case sensitive and can contain any characters except
  43newline (doublequote `"` and backslash have to be escaped as `\"` and `\\`,
  44respectively).  Section headers cannot span multiple
  45lines.  Variables may belong directly to a section or to a given subsection.
  46You can have `[section]` if you have `[section "subsection"]`, but you
  47don't need to.
  48
  49There is also a deprecated `[section.subsection]` syntax. With this
  50syntax, the subsection name is converted to lower-case and is also
  51compared case sensitively. These subsection names follow the same
  52restrictions as section names.
  53
  54All the other lines (and the remainder of the line after the section
  55header) are recognized as setting variables, in the form
  56'name = value'.  If there is no equal sign on the line, the entire line
  57is taken as 'name' and the variable is recognized as boolean "true".
  58The variable names are case-insensitive, allow only alphanumeric characters
  59and `-`, and must start with an alphabetic character.  There can be more
  60than one value for a given variable; we say then that the variable is
  61multivalued.
  62
  63Leading and trailing whitespace in a variable value is discarded.
  64Internal whitespace within a variable value is retained verbatim.
  65
  66The values following the equals sign in variable assign are all either
  67a string, an integer, or a boolean.  Boolean values may be given as yes/no,
  681/0, true/false or on/off.  Case is not significant in boolean values, when
  69converting value to the canonical form using '--bool' type specifier;
  70'git config' will ensure that the output is "true" or "false".
  71
  72String values may be entirely or partially enclosed in double quotes.
  73You need to enclose variable values in double quotes if you want to
  74preserve leading or trailing whitespace, or if the variable value contains
  75comment characters (i.e. it contains '#' or ';').
  76Double quote `"` and backslash `\` characters in variable values must
  77be escaped: use `\"` for `"` and `\\` for `\`.
  78
  79The following escape sequences (beside `\"` and `\\`) are recognized:
  80`\n` for newline character (NL), `\t` for horizontal tabulation (HT, TAB)
  81and `\b` for backspace (BS).  No other char escape sequence, nor octal
  82char sequences are valid.
  83
  84Variable values ending in a `\` are continued on the next line in the
  85customary UNIX fashion.
  86
  87Some variables may require a special value format.
  88
  89Includes
  90~~~~~~~~
  91
  92You can include one config file from another by setting the special
  93`include.path` variable to the name of the file to be included. The
  94included file is expanded immediately, as if its contents had been
  95found at the location of the include directive. If the value of the
  96`include.path` variable is a relative path, the path is considered to be
  97relative to the configuration file in which the include directive was
  98found. The value of `include.path` is subject to tilde expansion: `~/`
  99is expanded to the value of `$HOME`, and `~user/` to the specified
 100user's home directory. See below for examples.
 101
 102Example
 103~~~~~~~
 104
 105        # Core variables

 126                path = foo ; expand "foo" relative to the current file
 127                path = ~/foo ; expand "foo" in your $HOME directory

 129Variables
 130~~~~~~~~~
 131
 132Note that this list is non-comprehensive and not necessarily complete.
 133For command-specific variables, you will find a more detailed description
 134in the appropriate manual page. You will find a description of non-core
 135porcelain configuration variables in the respective porcelain documentation.
 136
 137advice.*::
 138        These variables control various optional help messages designed to
 139        aid new users. All 'advice.*' variables default to 'true', and you
 140        can tell Git that you do not need help by setting these to 'false':
 141+
 142--
 143        pushNonFastForward::
 144                Set this variable to 'false' if you want to disable
 145                'pushNonFFCurrent', 'pushNonFFDefault', and
 146                'pushNonFFMatching' simultaneously.
 147        pushNonFFCurrent::
 148                Advice shown when linkgit:git-push[1] fails due to a
 149                non-fast-forward update to the current branch.
 150        pushNonFFDefault::
 151                Advice to set 'push.default' to 'upstream' or 'current'
 152                when you ran linkgit:git-push[1] and pushed 'matching
 153                refs' by default (i.e. you did not provide an explicit
 154                refspec, and no 'push.default' configuration was set)
 155                and it resulted in a non-fast-forward error.
 156        pushNonFFMatching::
 157                Advice shown when you ran linkgit:git-push[1] and pushed
 158                'matching refs' explicitly (i.e. you used ':', or
 159                specified a refspec that isn't your current branch) and
 160                it resulted in a non-fast-forward error.
 161        statusHints::
 162                Show directions on how to proceed from the current
 163                state in the output of linkgit:git-status[1] and in
 164                the template shown when writing commit messages in
 165                linkgit:git-commit[1].
 166        commitBeforeMerge::
 167                Advice shown when linkgit:git-merge[1] refuses to
 168                merge to avoid overwriting local changes.
 169        resolveConflict::
 170                Advices shown by various commands when conflicts
 171                prevent the operation from being performed.
 172        implicitIdentity::
 173                Advice on how to set your identity configuration when
 174                your information is guessed from the system username and
 175                domain name.
 176        detachedHead::
 177                Advice shown when you used linkgit:git-checkout[1] to
 178                move to the detach HEAD state, to instruct how to create
 179                a local branch after the fact.
 180--
 181
 182core.fileMode::
 183        If false, the executable bit differences between the index and
 184        the working tree are ignored; useful on broken filesystems like FAT.
 185        See linkgit:git-update-index[1].
 186+
 187The default is true, except linkgit:git-clone[1] or linkgit:git-init[1]
 188will probe and set core.fileMode false if appropriate when the
 189repository is created.
 190
 191core.ignoreCygwinFSTricks::
 192        This option is only used by Cygwin implementation of Git. If false,
 193        the Cygwin stat() and lstat() functions are used. This may be useful
 194        if your repository consists of a few separate directories joined in
 195        one hierarchy using Cygwin mount. If true, Git uses native Win32 API
 196        whenever it is possible and falls back to Cygwin functions only to
 197        handle symbol links. The native mode is more than twice faster than
 198        normal Cygwin l/stat() functions. True by default, unless core.filemode
 199        is true, in which case ignoreCygwinFSTricks is ignored as Cygwin's
 200        POSIX emulation is required to support core.filemode.
 201
 202core.ignorecase::
 203        If true, this option enables various workarounds to enable
 204        git to work better on filesystems that are not case sensitive,
 205        like FAT. For example, if a directory listing finds
 206        "makefile" when git expects "Makefile", git will assume
 207        it is really the same file, and continue to remember it as
 208        "Makefile".
 209+
 210The default is false, except linkgit:git-clone[1] or linkgit:git-init[1]
 211will probe and set core.ignorecase true if appropriate when the repository
 212is created.
 213
 214core.precomposeunicode::
 215        This option is only used by Mac OS implementation of git.
 216        When core.precomposeunicode=true, git reverts the unicode decomposition
 217        of filenames done by Mac OS. This is useful when sharing a repository
 218        between Mac OS and Linux or Windows.
 219        (Git for Windows 1.7.10 or higher is needed, or git under cygwin 1.7).
 220        When false, file names are handled fully transparent by git,
 221        which is backward compatible with older versions of git.
 222
 223core.trustctime::
 224        If false, the ctime differences between the index and the
 225        working tree are ignored; useful when the inode change time
 226        is regularly modified by something outside Git (file system
 227        crawlers and some backup systems).
 228        See linkgit:git-update-index[1]. True by default.
 229
 230core.quotepath::
 231        The commands that output paths (e.g. 'ls-files',
 232        'diff'), when not given the `-z` option, will quote
 233        "unusual" characters in the pathname by enclosing the
 234        pathname in a double-quote pair and with backslashes the
 235        same way strings in C source code are quoted.  If this
 236        variable is set to false, the bytes higher than 0x80 are
 237        not quoted but output as verbatim.  Note that double
 238        quote, backslash and control characters are always
 239        quoted without `-z` regardless of the setting of this
 240        variable.
 241
 242core.eol::
 243        Sets the line ending type to use in the working directory for
 244        files that have the `text` property set.  Alternatives are
 245        'lf', 'crlf' and 'native', which uses the platform's native
 246        line ending.  The default value is `native`.  See
 247        linkgit:gitattributes[5] for more information on end-of-line
 248        conversion.
 249
 250core.safecrlf::
 251        If true, makes git check if converting `CRLF` is reversible when
 252        end-of-line conversion is active.  Git will verify if a command
 253        modifies a file in the work tree either directly or indirectly.
 254        For example, committing a file followed by checking out the
 255        same file should yield the original file in the work tree.  If
 256        this is not the case for the current setting of
 257        `core.autocrlf`, git will reject the file.  The variable can
 258        be set to "warn", in which case git will only warn about an
 259        irreversible conversion but continue the operation.
 260+
 261CRLF conversion bears a slight chance of corrupting data.
 262When it is enabled, git will convert CRLF to LF during commit and LF to
 263CRLF during checkout.  A file that contains a mixture of LF and
 264CRLF before the commit cannot be recreated by git.  For text
 265files this is the right thing to do: it corrects line endings
 266such that we have only LF line endings in the repository.
 267But for binary files that are accidentally classified as text the
 268conversion can corrupt data.
 269+
 270If you recognize such corruption early you can easily fix it by
 271setting the conversion type explicitly in .gitattributes.  Right
 272after committing you still have the original file in your work
 273tree and this file is not yet corrupted.  You can explicitly tell
 274git that this file is binary and git will handle the file
 275appropriately.
 276+
 277Unfortunately, the desired effect of cleaning up text files with
 278mixed line endings and the undesired effect of corrupting binary
 279files cannot be distinguished.  In both cases CRLFs are removed
 280in an irreversible way.  For text files this is the right thing
 281to do because CRLFs are line endings, while for binary files
 282converting CRLFs corrupts data.
 283+
 284Note, this safety check does not mean that a checkout will generate a
 285file identical to the original file for a different setting of
 286`core.eol` and `core.autocrlf`, but only for the current one.  For
 287example, a text file with `LF` would be accepted with `core.eol=lf`
 288and could later be checked out with `core.eol=crlf`, in which case the
 289resulting file would contain `CRLF`, although the original file
 290contained `LF`.  However, in both work trees the line endings would be
 291consistent, that is either all `LF` or all `CRLF`, but never mixed.  A
 292file with mixed line endings would be reported by the `core.safecrlf`
 293mechanism.
 294
 295core.autocrlf::
 296        Setting this variable to "true" is almost the same as setting
 297        the `text` attribute to "auto" on all files except that text
 298        files are not guaranteed to be normalized: files that contain
 299        `CRLF` in the repository will not be touched.  Use this
 300        setting if you want to have `CRLF` line endings in your
 301        working directory even though the repository does not have
 302        normalized line endings.  This variable can be set to 'input',
 303        in which case no output conversion is performed.
 304
 305core.symlinks::
 306        If false, symbolic links are checked out as small plain files that
 307        contain the link text. linkgit:git-update-index[1] and
 308        linkgit:git-add[1] will not change the recorded type to regular
 309        file. Useful on filesystems like FAT that do not support
 310        symbolic links.
 311+
 312The default is true, except linkgit:git-clone[1] or linkgit:git-init[1]
 313will probe and set core.symlinks false if appropriate when the repository
 314is created.
 315
 316core.gitProxy::
 317        A "proxy command" to execute (as 'command host port') instead
 318        of establishing direct connection to the remote server when
 319        using the git protocol for fetching. If the variable value is
 320        in the "COMMAND for DOMAIN" format, the command is applied only
 321        on hostnames ending with the specified domain string. This variable
 322        may be set multiple times and is matched in the given order;
 323        the first match wins.
 324+
 325Can be overridden by the 'GIT_PROXY_COMMAND' environment variable
 326(which always applies universally, without the special "for"
 327handling).
 328+
 329The special string `none` can be used as the proxy command to
 330specify that no proxy be used for a given domain pattern.
 331This is useful for excluding servers inside a firewall from
 332proxy use, while defaulting to a common proxy for external domains.
 333
 334core.ignoreStat::
 335        If true, commands which modify both the working tree and the index
 336        will mark the updated paths with the "assume unchanged" bit in the
 337        index. These marked files are then assumed to stay unchanged in the
 338        working tree, until you mark them otherwise manually - Git will not
 339        detect the file changes by lstat() calls. This is useful on systems
 340        where those are very slow, such as Microsoft Windows.
 341        See linkgit:git-update-index[1].
 342        False by default.
 343
 344core.preferSymlinkRefs::
 345        Instead of the default "symref" format for HEAD
 346        and other symbolic reference files, use symbolic links.
 347        This is sometimes needed to work with old scripts that
 348        expect HEAD to be a symbolic link.
 349
 350core.bare::
 351        If true this repository is assumed to be 'bare' and has no
 352        working directory associated with it.  If this is the case a
 353        number of commands that require a working directory will be
 354        disabled, such as linkgit:git-add[1] or linkgit:git-merge[1].
 355+
 356This setting is automatically guessed by linkgit:git-clone[1] or
 357linkgit:git-init[1] when the repository was created.  By default a
 358repository that ends in "/.git" is assumed to be not bare (bare =
 359false), while all other repositories are assumed to be bare (bare
 360= true).
 361
 362core.worktree::
 363        Set the path to the root of the working tree.
 364        This can be overridden by the GIT_WORK_TREE environment
 365        variable and the '--work-tree' command line option.
 366        The value can be an absolute path or relative to the path to
 367        the .git directory, which is either specified by --git-dir
 368        or GIT_DIR, or automatically discovered.
 369        If --git-dir or GIT_DIR is specified but none of
 370        --work-tree, GIT_WORK_TREE and core.worktree is specified,
 371        the current working directory is regarded as the top level
 372        of your working tree.
 373+
 374Note that this variable is honored even when set in a configuration
 375file in a ".git" subdirectory of a directory and its value differs
 376from the latter directory (e.g. "/path/to/.git/config" has
 377core.worktree set to "/different/path"), which is most likely a
 378misconfiguration.  Running git commands in the "/path/to" directory will
 379still use "/different/path" as the root of the work tree and can cause
 380confusion unless you know what you are doing (e.g. you are creating a
 381read-only snapshot of the same index to a location different from the
 382repository's usual working tree).
 383
 384core.logAllRefUpdates::
 385        Enable the reflog. Updates to a ref <ref> is logged to the file
 386        "$GIT_DIR/logs/<ref>", by appending the new and old
 387        SHA1, the date/time and the reason of the update, but
 388        only when the file exists.  If this configuration
 389        variable is set to true, missing "$GIT_DIR/logs/<ref>"
 390        file is automatically created for branch heads (i.e. under
 391        refs/heads/), remote refs (i.e. under refs/remotes/),
 392        note refs (i.e. under refs/notes/), and the symbolic ref HEAD.
 393+
 394This information can be used to determine what commit
 395was the tip of a branch "2 days ago".
 396+
 397This value is true by default in a repository that has
 398a working directory associated with it, and false by
 399default in a bare repository.
 400
 401core.repositoryFormatVersion::
 402        Internal variable identifying the repository format and layout
 403        version.
 404
 405core.sharedRepository::
 406        When 'group' (or 'true'), the repository is made shareable between
 407        several users in a group (making sure all the files and objects are
 408        group-writable). When 'all' (or 'world' or 'everybody'), the
 409        repository will be readable by all users, additionally to being
 410        group-shareable. When 'umask' (or 'false'), git will use permissions
 411        reported by umask(2). When '0xxx', where '0xxx' is an octal number,
 412        files in the repository will have this mode value. '0xxx' will override
 413        user's umask value (whereas the other options will only override
 414        requested parts of the user's umask value). Examples: '0660' will make
 415        the repo read/write-able for the owner and group, but inaccessible to
 416        others (equivalent to 'group' unless umask is e.g. '0022'). '0640' is a
 417        repository that is group-readable but not group-writable.
 418        See linkgit:git-init[1]. False by default.
 419
 420core.warnAmbiguousRefs::
 421        If true, git will warn you if the ref name you passed it is ambiguous
 422        and might match multiple refs in the .git/refs/ tree. True by default.
 423
 424core.compression::
 425        An integer -1..9, indicating a default compression level.
 426        -1 is the zlib default. 0 means no compression,
 427        and 1..9 are various speed/size tradeoffs, 9 being slowest.
 428        If set, this provides a default to other compression variables,
 429        such as 'core.loosecompression' and 'pack.compression'.
 430
 431core.loosecompression::
 432        An integer -1..9, indicating the compression level for objects that
 433        are not in a pack file. -1 is the zlib default. 0 means no
 434        compression, and 1..9 are various speed/size tradeoffs, 9 being
 435        slowest.  If not set,  defaults to core.compression.  If that is
 436        not set,  defaults to 1 (best speed).
 437
 438core.packedGitWindowSize::
 439        Number of bytes of a pack file to map into memory in a
 440        single mapping operation.  Larger window sizes may allow
 441        your system to process a smaller number of large pack files
 442        more quickly.  Smaller window sizes will negatively affect
 443        performance due to increased calls to the operating system's
 444        memory manager, but may improve performance when accessing
 445        a large number of large pack files.
 446+
 447Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
 448MiB on 32 bit platforms and 1 GiB on 64 bit platforms.  This should
 449be reasonable for all users/operating systems.  You probably do
 450not need to adjust this value.
 451+
 452Common unit suffixes of 'k', 'm', or 'g' are supported.
 453
 454core.packedGitLimit::
 455        Maximum number of bytes to map simultaneously into memory
 456        from pack files.  If Git needs to access more than this many
 457        bytes at once to complete an operation it will unmap existing
 458        regions to reclaim virtual address space within the process.
 459+
 460Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms.
 461This should be reasonable for all users/operating systems, except on
 462the largest projects.  You probably do not need to adjust this value.
 463+
 464Common unit suffixes of 'k', 'm', or 'g' are supported.
 465
 466core.deltaBaseCacheLimit::
 467        Maximum number of bytes to reserve for caching base objects
 468        that may be referenced by multiple deltified objects.  By storing the
 469        entire decompressed base objects in a cache Git is able
 470        to avoid unpacking and decompressing frequently used base
 471        objects multiple times.
 472+
 473Default is 16 MiB on all platforms.  This should be reasonable
 474for all users/operating systems, except on the largest projects.
 475You probably do not need to adjust this value.
 476+
 477Common unit suffixes of 'k', 'm', or 'g' are supported.
 478
 479core.bigFileThreshold::
 480        Files larger than this size are stored deflated, without
 481        attempting delta compression.  Storing large files without
 482        delta compression avoids excessive memory usage, at the
 483        slight expense of increased disk usage.
 484+
 485Default is 512 MiB on all platforms.  This should be reasonable
 486for most projects as source code and other text files can still
 487be delta compressed, but larger binary media files won't be.
 488+
 489Common unit suffixes of 'k', 'm', or 'g' are supported.
 490
 491core.excludesfile::
 492        In addition to '.gitignore' (per-directory) and
 493        '.git/info/exclude', git looks into this file for patterns
 494        of files which are not meant to be tracked.  "`~/`" is expanded
 495        to the value of `$HOME` and "`~user/`" to the specified user's
 496        home directory. Its default value is $XDG_CONFIG_HOME/git/ignore.
 497        If $XDG_CONFIG_HOME is either not set or empty, $HOME/.config/git/ignore
 498        is used instead. See linkgit:gitignore[5].
 499
 500core.askpass::
 501        Some commands (e.g. svn and http interfaces) that interactively
 502        ask for a password can be told to use an external program given
 503        via the value of this variable. Can be overridden by the 'GIT_ASKPASS'
 504        environment variable. If not set, fall back to the value of the
 505        'SSH_ASKPASS' environment variable or, failing that, a simple password
 506        prompt. The external program shall be given a suitable prompt as
 507        command line argument and write the password on its STDOUT.
 508
 509core.attributesfile::
 510        In addition to '.gitattributes' (per-directory) and
 511        '.git/info/attributes', git looks into this file for attributes
 512        (see linkgit:gitattributes[5]). Path expansions are made the same
 513        way as for `core.excludesfile`. Its default value is
 514        $XDG_CONFIG_HOME/git/attributes. If $XDG_CONFIG_HOME is either not
 515        set or empty, $HOME/.config/git/attributes is used instead.
 516
 517core.editor::
 518        Commands such as `commit` and `tag` that lets you edit
 519        messages by launching an editor uses the value of this
 520        variable when it is set, and the environment variable
 521        `GIT_EDITOR` is not set.  See linkgit:git-var[1].
 522
 523sequence.editor::
 524        Text editor used by `git rebase -i` for editing the rebase insn file.
 525        The value is meant to be interpreted by the shell when it is used.
 526        It can be overridden by the `GIT_SEQUENCE_EDITOR` environment variable.
 527        When not configured the default commit message editor is used instead.
 528
 529core.pager::
 530        The command that git will use to paginate output.  Can
 531        be overridden with the `GIT_PAGER` environment
 532        variable.  Note that git sets the `LESS` environment
 533        variable to `FRSX` if it is unset when it runs the
 534        pager.  One can change these settings by setting the
 535        `LESS` variable to some other value.  Alternately,
 536        these settings can be overridden on a project or
 537        global basis by setting the `core.pager` option.
 538        Setting `core.pager` has no affect on the `LESS`
 539        environment variable behaviour above, so if you want
 540        to override git's default settings this way, you need
 541        to be explicit.  For example, to disable the S option
 542        in a backward compatible manner, set `core.pager`
 543        to `less -+$LESS -FRX`.  This will be passed to the
 544        shell by git, which will translate the final command to
 545        `LESS=FRSX less -+FRSX -FRX`.
 546
 547core.whitespace::
 548        A comma separated list of common whitespace problems to
 549        notice.  'git diff' will use `color.diff.whitespace` to
 550        highlight them, and 'git apply --whitespace=error' will
 551        consider them as errors.  You can prefix `-` to disable
 552        any of them (e.g. `-trailing-space`):
 553+
 554* `blank-at-eol` treats trailing whitespaces at the end of the line
 555  as an error (enabled by default).
 556* `space-before-tab` treats a space character that appears immediately
 557  before a tab character in the initial indent part of the line as an
 558  error (enabled by default).
 559* `indent-with-non-tab` treats a line that is indented with 8 or more
 560  space characters as an error (not enabled by default).
 561* `tab-in-indent` treats a tab character in the initial indent part of
 562  the line as an error (not enabled by default).
 563* `blank-at-eof` treats blank lines added at the end of file as an error
 564  (enabled by default).
 565* `trailing-space` is a short-hand to cover both `blank-at-eol` and
 566  `blank-at-eof`.
 567* `cr-at-eol` treats a carriage-return at the end of line as
 568  part of the line terminator, i.e. with it, `trailing-space`
 569  does not trigger if the character before such a carriage-return
 570  is not a whitespace (not enabled by default).
 571* `tabwidth=<n>` tells how many character positions a tab occupies; this
 572  is relevant for `indent-with-non-tab` and when git fixes `tab-in-indent`
 573  errors. The default tab width is 8. Allowed values are 1 to 63.
 574
 575core.fsyncobjectfiles::
 576        This boolean will enable 'fsync()' when writing object files.
 577+
 578This is a total waste of time and effort on a filesystem that orders
 579data writes properly, but can be useful for filesystems that do not use
 580journalling (traditional UNIX filesystems) or that only journal metadata
 581and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback").
 582
 583core.preloadindex::
 584        Enable parallel index preload for operations like 'git diff'
 585+
 586This can speed up operations like 'git diff' and 'git status' especially
 587on filesystems like NFS that have weak caching semantics and thus
 588relatively high IO latencies.  With this set to 'true', git will do the
 589index comparison to the filesystem data in parallel, allowing
 590overlapping IO's.
 591
 592core.createObject::
 593        You can set this to 'link', in which case a hardlink followed by
 594        a delete of the source are used to make sure that object creation
 595        will not overwrite existing objects.
 596+
 597On some file system/operating system combinations, this is unreliable.
 598Set this config setting to 'rename' there; However, This will remove the
 599check that makes sure that existing object files will not get overwritten.
 600
 601core.notesRef::
 602        When showing commit messages, also show notes which are stored in
 603        the given ref.  The ref must be fully qualified.  If the given
 604        ref does not exist, it is not an error but means that no
 605        notes should be printed.
 606+
 607This setting defaults to "refs/notes/commits", and it can be overridden by
 608the 'GIT_NOTES_REF' environment variable.  See linkgit:git-notes[1].
 609
 610core.sparseCheckout::
 611        Enable "sparse checkout" feature. See section "Sparse checkout" in
 612        linkgit:git-read-tree[1] for more information.
 613
 614core.abbrev::
 615        Set the length object names are abbreviated to.  If unspecified,
 616        many commands abbreviate to 7 hexdigits, which may not be enough
 617        for abbreviated object names to stay unique for sufficiently long
 618        time.
 619
 620add.ignore-errors::
 621add.ignoreErrors::
 622        Tells 'git add' to continue adding files when some files cannot be
 623        added due to indexing errors. Equivalent to the '--ignore-errors'
 624        option of linkgit:git-add[1].  Older versions of git accept only
 625        `add.ignore-errors`, which does not follow the usual naming
 626        convention for configuration variables.  Newer versions of git
 627        honor `add.ignoreErrors` as well.
 628
 629alias.*::
 630        Command aliases for the linkgit:git[1] command wrapper - e.g.
 631        after defining "alias.last = cat-file commit HEAD", the invocation
 632        "git last" is equivalent to "git cat-file commit HEAD". To avoid
 633        confusion and troubles with script usage, aliases that
 634        hide existing git commands are ignored. Arguments are split by
 635        spaces, the usual shell quoting and escaping is supported.
 636        quote pair and a backslash can be used to quote them.
 637+
 638If the alias expansion is prefixed with an exclamation point,
 639it will be treated as a shell command.  For example, defining
 640"alias.new = !gitk --all --not ORIG_HEAD", the invocation
 641"git new" is equivalent to running the shell command
 642"gitk --all --not ORIG_HEAD".  Note that shell commands will be
 643executed from the top-level directory of a repository, which may
 644not necessarily be the current directory.
 645'GIT_PREFIX' is set as returned by running 'git rev-parse --show-prefix'
 646from the original current directory. See linkgit:git-rev-parse[1].
 647
 648am.keepcr::
 649        If true, git-am will call git-mailsplit for patches in mbox format
 650        with parameter '--keep-cr'. In this case git-mailsplit will
 651        not remove `\r` from lines ending with `\r\n`. Can be overridden
 652        by giving '--no-keep-cr' from the command line.
 653        See linkgit:git-am[1], linkgit:git-mailsplit[1].
 654
 655apply.ignorewhitespace::
 656        When set to 'change', tells 'git apply' to ignore changes in
 657        whitespace, in the same way as the '--ignore-space-change'
 658        option.
 659        When set to one of: no, none, never, false tells 'git apply' to
 660        respect all whitespace differences.
 661        See linkgit:git-apply[1].
 662
 663apply.whitespace::
 664        Tells 'git apply' how to handle whitespaces, in the same way
 665        as the '--whitespace' option. See linkgit:git-apply[1].
 666
 667branch.autosetupmerge::
 668        Tells 'git branch' and 'git checkout' to set up new branches
 669        so that linkgit:git-pull[1] will appropriately merge from the
 670        starting point branch. Note that even if this option is not set,
 671        this behavior can be chosen per-branch using the `--track`
 672        and `--no-track` options. The valid settings are: `false` -- no
 673        automatic setup is done; `true` -- automatic setup is done when the
 674        starting point is a remote-tracking branch; `always` --
 675        automatic setup is done when the starting point is either a
 676        local branch or remote-tracking
 677        branch. This option defaults to true.
 678
 679branch.autosetuprebase::
 680        When a new branch is created with 'git branch' or 'git checkout'
 681        that tracks another branch, this variable tells git to set
 682        up pull to rebase instead of merge (see "branch.<name>.rebase").
 683        When `never`, rebase is never automatically set to true.
 684        When `local`, rebase is set to true for tracked branches of
 685        other local branches.
 686        When `remote`, rebase is set to true for tracked branches of
 687        remote-tracking branches.
 688        When `always`, rebase will be set to true for all tracking
 689        branches.
 690        See "branch.autosetupmerge" for details on how to set up a
 691        branch to track another branch.
 692        This option defaults to never.
 693
 694branch.<name>.remote::
 695        When in branch <name>, it tells 'git fetch' and 'git push' which
 696        remote to fetch from/push to.  It defaults to `origin` if no remote is
 697        configured. `origin` is also used if you are not on any branch.
 698
 699branch.<name>.merge::
 700        Defines, together with branch.<name>.remote, the upstream branch
 701        for the given branch. It tells 'git fetch'/'git pull'/'git rebase' which
 702        branch to merge and can also affect 'git push' (see push.default).
 703        When in branch <name>, it tells 'git fetch' the default
 704        refspec to be marked for merging in FETCH_HEAD. The value is
 705        handled like the remote part of a refspec, and must match a
 706        ref which is fetched from the remote given by
 707        "branch.<name>.remote".
 708        The merge information is used by 'git pull' (which at first calls
 709        'git fetch') to lookup the default branch for merging. Without
 710        this option, 'git pull' defaults to merge the first refspec fetched.
 711        Specify multiple values to get an octopus merge.
 712        If you wish to setup 'git pull' so that it merges into <name> from
 713        another branch in the local repository, you can point
 714        branch.<name>.merge to the desired branch, and use the special setting
 715        `.` (a period) for branch.<name>.remote.
 716
 717branch.<name>.mergeoptions::
 718        Sets default options for merging into branch <name>. The syntax and
 719        supported options are the same as those of linkgit:git-merge[1], but
 720        option values containing whitespace characters are currently not
 721        supported.
 722
 723branch.<name>.rebase::
 724        When true, rebase the branch <name> on top of the fetched branch,
 725        instead of merging the default branch from the default remote when
 726        "git pull" is run. See "pull.rebase" for doing this in a non
 727        branch-specific manner.
 728+
 729*NOTE*: this is a possibly dangerous operation; do *not* use
 730it unless you understand the implications (see linkgit:git-rebase[1]
 731for details).
 732
 733browser.<tool>.cmd::
 734        Specify the command to invoke the specified browser. The
 735        specified command is evaluated in shell with the URLs passed
 736        as arguments. (See linkgit:git-web{litdd}browse[1].)
 737
 738browser.<tool>.path::
 739        Override the path for the given tool that may be used to
 740        browse HTML help (see '-w' option in linkgit:git-help[1]) or a
 741        working repository in gitweb (see linkgit:git-instaweb[1]).
 742
 743clean.requireForce::
 744        A boolean to make git-clean do nothing unless given -f
 745        or -n.   Defaults to true.
 746
 747color.branch::
 748        A boolean to enable/disable color in the output of
 749        linkgit:git-branch[1]. May be set to `always`,
 750        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 751        only when the output is to a terminal. Defaults to false.
 752
 753color.branch.<slot>::
 754        Use customized color for branch coloration. `<slot>` is one of
 755        `current` (the current branch), `local` (a local branch),
 756        `remote` (a remote-tracking branch in refs/remotes/), `plain` (other
 757        refs).
 758+
 759The value for these configuration variables is a list of colors (at most
 760two) and attributes (at most one), separated by spaces.  The colors
 761accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`,
 762`magenta`, `cyan` and `white`; the attributes are `bold`, `dim`, `ul`,
 763`blink` and `reverse`.  The first color given is the foreground; the
 764second is the background.  The position of the attribute, if any,
 765doesn't matter.
 766
 767color.diff::
 768        Whether to use ANSI escape sequences to add color to patches.
 769        If this is set to `always`, linkgit:git-diff[1],
 770        linkgit:git-log[1], and linkgit:git-show[1] will use color
 771        for all patches.  If it is set to `true` or `auto`, those
 772        commands will only use color when output is to the terminal.
 773        Defaults to false.
 774+
 775This does not affect linkgit:git-format-patch[1] nor the
 776'git-diff-{asterisk}' plumbing commands.  Can be overridden on the
 777command line with the `--color[=<when>]` option.
 778
 779color.diff.<slot>::
 780        Use customized color for diff colorization.  `<slot>` specifies
 781        which part of the patch to use the specified color, and is one
 782        of `plain` (context text), `meta` (metainformation), `frag`
 783        (hunk header), 'func' (function in hunk header), `old` (removed lines),
 784        `new` (added lines), `commit` (commit headers), or `whitespace`
 785        (highlighting whitespace errors). The values of these variables may be
 786        specified as in color.branch.<slot>.
 787
 788color.decorate.<slot>::
 789        Use customized color for 'git log --decorate' output.  `<slot>` is one
 790        of `branch`, `remoteBranch`, `tag`, `stash` or `HEAD` for local
 791        branches, remote-tracking branches, tags, stash and HEAD, respectively.
 792
 793color.grep::
 794        When set to `always`, always highlight matches.  When `false` (or
 795        `never`), never.  When set to `true` or `auto`, use color only
 796        when the output is written to the terminal.  Defaults to `false`.
 797
 798color.grep.<slot>::
 799        Use customized color for grep colorization.  `<slot>` specifies which
 800        part of the line to use the specified color, and is one of
 801+
 802--
 803`context`;;
 804        non-matching text in context lines (when using `-A`, `-B`, or `-C`)
 805`filename`;;

 820The values of these variables may be specified as in color.branch.<slot>.
 821
 822color.interactive::
 823        When set to `always`, always use colors for interactive prompts
 824        and displays (such as those used by "git-add --interactive").
 825        When false (or `never`), never.  When set to `true` or `auto`, use
 826        colors only when the output is to the terminal. Defaults to false.
 827
 828color.interactive.<slot>::
 829        Use customized color for 'git add --interactive'
 830        output. `<slot>` may be `prompt`, `header`, `help` or `error`, for
 831        four distinct types of normal output from interactive
 832        commands.  The values of these variables may be specified as
 833        in color.branch.<slot>.
 834
 835color.pager::
 836        A boolean to enable/disable colored output when the pager is in
 837        use (default is true).
 838
 839color.showbranch::
 840        A boolean to enable/disable color in the output of
 841        linkgit:git-show-branch[1]. May be set to `always`,
 842        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 843        only when the output is to a terminal. Defaults to false.
 844
 845color.status::
 846        A boolean to enable/disable color in the output of
 847        linkgit:git-status[1]. May be set to `always`,
 848        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 849        only when the output is to a terminal. Defaults to false.
 850
 851color.status.<slot>::
 852        Use customized color for status colorization. `<slot>` is
 853        one of `header` (the header text of the status message),
 854        `added` or `updated` (files which are added but not committed),
 855        `changed` (files which are changed but not added in the index),
 856        `untracked` (files which are not tracked by git),
 857        `branch` (the current branch), or
 858        `nobranch` (the color the 'no branch' warning is shown in, defaulting
 859        to red). The values of these variables may be specified as in
 860        color.branch.<slot>.
 861
 862color.ui::
 863        This variable determines the default value for variables such
 864        as `color.diff` and `color.grep` that control the use of color
 865        per command family. Its scope will expand as more commands learn
 866        configuration to set a default for the `--color` option.  Set it
 867        to `always` if you want all output not intended for machine
 868        consumption to use color, to `true` or `auto` if you want such
 869        output to use color when written to the terminal, or to `false` or
 870        `never` if you prefer git commands not to use color unless enabled
 871        explicitly with some other configuration or the `--color` option.
 872
 873column.ui::
 874        Specify whether supported commands should output in columns.
 875        This variable consists of a list of tokens separated by spaces
 876        or commas:
 877+
 878--
 879`always`;;
 880        always show in columns
 881`never`;;
 882        never show in columns
 883`auto`;;
 884        show in columns if the output is to the terminal
 885`column`;;
 886        fill columns before rows (default)
 887`row`;;
 888        fill rows before columns
 889`plain`;;
 890        show in one column
 891`dense`;;
 892        make unequal size columns to utilize more space
 893`nodense`;;
 894        make equal size columns
 895--
 896+
 897This option defaults to 'never'.
 898
 899column.branch::
 900        Specify whether to output branch listing in `git branch` in columns.
 901        See `column.ui` for details.
 902
 903column.status::
 904        Specify whether to output untracked files in `git status` in columns.
 905        See `column.ui` for details.
 906
 907column.tag::
 908        Specify whether to output tag listing in `git tag` in columns.
 909        See `column.ui` for details.
 910
 911commit.status::
 912        A boolean to enable/disable inclusion of status information in the
 913        commit message template when using an editor to prepare the commit
 914        message.  Defaults to true.
 915
 916commit.template::
 917        Specify a file to use as the template for new commit messages.
 918        "`~/`" is expanded to the value of `$HOME` and "`~user/`" to the
 919        specified user's home directory.
 920
 921credential.helper::
 922        Specify an external helper to be called when a username or
 923        password credential is needed; the helper may consult external
 924        storage to avoid prompting the user for the credentials. See
 925        linkgit:gitcredentials[7] for details.
 926
 927credential.useHttpPath::
 928        When acquiring credentials, consider the "path" component of an http
 929        or https URL to be important. Defaults to false. See
 930        linkgit:gitcredentials[7] for more information.
 931
 932credential.username::
 933        If no username is set for a network authentication, use this username
 934        by default. See credential.<context>.* below, and
 935        linkgit:gitcredentials[7].
 936
 937credential.<url>.*::
 938        Any of the credential.* options above can be applied selectively to
 939        some credentials. For example "credential.https://example.com.username"
 940        would set the default username only for https connections to
 941        example.com. See linkgit:gitcredentials[7] for details on how URLs are
 942        matched.
 943
 944include::diff-config.txt[]
 945
 946difftool.<tool>.path::
 947        Override the path for the given tool.  This is useful in case
 948        your tool is not in the PATH.
 949
 950difftool.<tool>.cmd::
 951        Specify the command to invoke the specified diff tool.
 952        The specified command is evaluated in shell with the following
 953        variables available:  'LOCAL' is set to the name of the temporary
 954        file containing the contents of the diff pre-image and 'REMOTE'
 955        is set to the name of the temporary file containing the contents
 956        of the diff post-image.
 957
 958difftool.prompt::
 959        Prompt before each invocation of the diff tool.
 960
 961diff.wordRegex::
 962        A POSIX Extended Regular Expression used to determine what is a "word"
 963        when performing word-by-word difference calculations.  Character
 964        sequences that match the regular expression are "words", all other
 965        characters are *ignorable* whitespace.
 966
 967fetch.recurseSubmodules::
 968        This option can be either set to a boolean value or to 'on-demand'.
 969        Setting it to a boolean changes the behavior of fetch and pull to
 970        unconditionally recurse into submodules when set to true or to not
 971        recurse at all when set to false. When set to 'on-demand' (the default
 972        value), fetch and pull will only recurse into a populated submodule
 973        when its superproject retrieves a commit that updates the submodule's
 974        reference.
 975
 976fetch.fsckObjects::
 977        If it is set to true, git-fetch-pack will check all fetched
 978        objects. It will abort in the case of a malformed object or a
 979        broken link. The result of an abort are only dangling objects.
 980        Defaults to false. If not set, the value of `transfer.fsckObjects`
 981        is used instead.
 982
 983fetch.unpackLimit::
 984        If the number of objects fetched over the git native
 985        transfer is below this
 986        limit, then the objects will be unpacked into loose object
 987        files. However if the number of received objects equals or
 988        exceeds this limit then the received pack will be stored as
 989        a pack, after adding any missing delta bases.  Storing the
 990        pack from a push can make the push operation complete faster,
 991        especially on slow filesystems.  If not set, the value of
 992        `transfer.unpackLimit` is used instead.
 993
 994format.attach::
 995        Enable multipart/mixed attachments as the default for
 996        'format-patch'.  The value can also be a double quoted string
 997        which will enable attachments as the default and set the
 998        value as the boundary.  See the --attach option in
 999        linkgit:git-format-patch[1].
1000
1001format.numbered::
1002        A boolean which can enable or disable sequence numbers in patch
1003        subjects.  It defaults to "auto" which enables it only if there
1004        is more than one patch.  It can be enabled or disabled for all
1005        messages by setting it to "true" or "false".  See --numbered
1006        option in linkgit:git-format-patch[1].
1007
1008format.headers::
1009        Additional email headers to include in a patch to be submitted
1010        by mail.  See linkgit:git-format-patch[1].
1011
1012format.to::
1013format.cc::
1014        Additional recipients to include in a patch to be submitted
1015        by mail.  See the --to and --cc options in
1016        linkgit:git-format-patch[1].
1017
1018format.subjectprefix::
1019        The default for format-patch is to output files with the '[PATCH]'
1020        subject prefix. Use this variable to change that prefix.
1021
1022format.signature::
1023        The default for format-patch is to output a signature containing
1024        the git version number. Use this variable to change that default.
1025        Set this variable to the empty string ("") to suppress
1026        signature generation.
1027
1028format.suffix::
1029        The default for format-patch is to output files with the suffix
1030        `.patch`. Use this variable to change that suffix (make sure to
1031        include the dot if you want it).
1032
1033format.pretty::
1034        The default pretty format for log/show/whatchanged command,
1035        See linkgit:git-log[1], linkgit:git-show[1],
1036        linkgit:git-whatchanged[1].
1037
1038format.thread::
1039        The default threading style for 'git format-patch'.  Can be
1040        a boolean value, or `shallow` or `deep`.  `shallow` threading
1041        makes every mail a reply to the head of the series,
1042        where the head is chosen from the cover letter, the
1043        `--in-reply-to`, and the first patch mail, in this order.
1044        `deep` threading makes every mail a reply to the previous one.
1045        A true boolean value is the same as `shallow`, and a false
1046        value disables threading.
1047
1048format.signoff::
1049    A boolean value which lets you enable the `-s/--signoff` option of
1050    format-patch by default. *Note:* Adding the Signed-off-by: line to a
1051    patch should be a conscious act and means that you certify you have
1052    the rights to submit this work under the same open source license.
1053    Please see the 'SubmittingPatches' document for further discussion.
1054
1055filter.<driver>.clean::
1056        The command which is used to convert the content of a worktree
1057        file to a blob upon checkin.  See linkgit:gitattributes[5] for
1058        details.
1059
1060filter.<driver>.smudge::
1061        The command which is used to convert the content of a blob
1062        object to a worktree file upon checkout.  See
1063        linkgit:gitattributes[5] for details.
1064
1065gc.aggressiveWindow::
1066        The window size parameter used in the delta compression
1067        algorithm used by 'git gc --aggressive'.  This defaults
1068        to 250.
1069
1070gc.auto::
1071        When there are approximately more than this many loose
1072        objects in the repository, `git gc --auto` will pack them.
1073        Some Porcelain commands use this command to perform a
1074        light-weight garbage collection from time to time.  The
1075        default value is 6700.  Setting this to 0 disables it.
1076
1077gc.autopacklimit::
1078        When there are more than this many packs that are not
1079        marked with `*.keep` file in the repository, `git gc
1080        --auto` consolidates them into one larger pack.  The
1081        default value is 50.  Setting this to 0 disables it.
1082
1083gc.packrefs::
1084        Running `git pack-refs` in a repository renders it
1085        unclonable by Git versions prior to 1.5.1.2 over dumb
1086        transports such as HTTP.  This variable determines whether
1087        'git gc' runs `git pack-refs`. This can be set to `notbare`
1088        to enable it within all non-bare repos or it can be set to a
1089        boolean value.  The default is `true`.
1090
1091gc.pruneexpire::
1092        When 'git gc' is run, it will call 'prune --expire 2.weeks.ago'.
1093        Override the grace period with this config variable.  The value
1094        "now" may be used to disable this  grace period and always prune
1095        unreachable objects immediately.
1096
1097gc.reflogexpire::
1098gc.<pattern>.reflogexpire::
1099        'git reflog expire' removes reflog entries older than
1100        this time; defaults to 90 days.  With "<pattern>" (e.g.
1101        "refs/stash") in the middle the setting applies only to
1102        the refs that match the <pattern>.
1103
1104gc.reflogexpireunreachable::
1105gc.<ref>.reflogexpireunreachable::
1106        'git reflog expire' removes reflog entries older than
1107        this time and are not reachable from the current tip;
1108        defaults to 30 days.  With "<pattern>" (e.g. "refs/stash")
1109        in the middle, the setting applies only to the refs that
1110        match the <pattern>.
1111
1112gc.rerereresolved::
1113        Records of conflicted merge you resolved earlier are
1114        kept for this many days when 'git rerere gc' is run.
1115        The default is 60 days.  See linkgit:git-rerere[1].
1116
1117gc.rerereunresolved::
1118        Records of conflicted merge you have not resolved are
1119        kept for this many days when 'git rerere gc' is run.
1120        The default is 15 days.  See linkgit:git-rerere[1].
1121
1122gitcvs.commitmsgannotation::
1123        Append this string to each commit message. Set to empty string
1124        to disable this feature. Defaults to "via git-CVS emulator".
1125
1126gitcvs.enabled::
1127        Whether the CVS server interface is enabled for this repository.
1128        See linkgit:git-cvsserver[1].
1129
1130gitcvs.logfile::
1131        Path to a log file where the CVS server interface well... logs
1132        various stuff. See linkgit:git-cvsserver[1].
1133
1134gitcvs.usecrlfattr::
1135        If true, the server will look up the end-of-line conversion
1136        attributes for files to determine the '-k' modes to use. If
1137        the attributes force git to treat a file as text,
1138        the '-k' mode will be left blank so CVS clients will
1139        treat it as text. If they suppress text conversion, the file
1140        will be set with '-kb' mode, which suppresses any newline munging
1141        the client might otherwise do. If the attributes do not allow
1142        the file type to be determined, then 'gitcvs.allbinary' is
1143        used. See linkgit:gitattributes[5].
1144
1145gitcvs.allbinary::
1146        This is used if 'gitcvs.usecrlfattr' does not resolve
1147        the correct '-kb' mode to use. If true, all
1148        unresolved files are sent to the client in
1149        mode '-kb'. This causes the client to treat them
1150        as binary files, which suppresses any newline munging it
1151        otherwise might do. Alternatively, if it is set to "guess",
1152        then the contents of the file are examined to decide if
1153        it is binary, similar to 'core.autocrlf'.
1154
1155gitcvs.dbname::
1156        Database used by git-cvsserver to cache revision information
1157        derived from the git repository. The exact meaning depends on the
1158        used database driver, for SQLite (which is the default driver) this
1159        is a filename. Supports variable substitution (see
1160        linkgit:git-cvsserver[1] for details). May not contain semicolons (`;`).
1161        Default: '%Ggitcvs.%m.sqlite'
1162
1163gitcvs.dbdriver::
1164        Used Perl DBI driver. You can specify any available driver
1165        for this here, but it might not work. git-cvsserver is tested
1166        with 'DBD::SQLite', reported to work with 'DBD::Pg', and
1167        reported *not* to work with 'DBD::mysql'. Experimental feature.
1168        May not contain double colons (`:`). Default: 'SQLite'.
1169        See linkgit:git-cvsserver[1].
1170
1171gitcvs.dbuser, gitcvs.dbpass::
1172        Database user and password. Only useful if setting 'gitcvs.dbdriver',
1173        since SQLite has no concept of database users and/or passwords.
1174        'gitcvs.dbuser' supports variable substitution (see
1175        linkgit:git-cvsserver[1] for details).
1176
1177gitcvs.dbTableNamePrefix::
1178        Database table name prefix.  Prepended to the names of any
1179        database tables used, allowing a single database to be used
1180        for several repositories.  Supports variable substitution (see
1181        linkgit:git-cvsserver[1] for details).  Any non-alphabetic
1182        characters will be replaced with underscores.
1183
1184All gitcvs variables except for 'gitcvs.usecrlfattr' and
1185'gitcvs.allbinary' can also be specified as
1186'gitcvs.<access_method>.<varname>' (where 'access_method'
1187is one of "ext" and "pserver") to make them apply only for the given
1188access method.

1211        If set to true, enable '--extended-regexp' option by default.
1212
1213gpg.program::
1214        Use this custom program instead of "gpg" found on $PATH when
1215        making or verifying a PGP signature. The program must support the
1216        same command line interface as GPG, namely, to verify a detached
1217        signature, "gpg --verify $file - <$signature" is run, and the
1218        program is expected to signal a good signature by exiting with
1219        code 0, and to generate an ascii-armored detached signature, the
1220        standard input of "gpg -bsau $key" is fed with the contents to be
1221        signed, and the program is expected to send the result to its
1222        standard output.
1223
1224gui.commitmsgwidth::
1225        Defines how wide the commit message window is in the
1226        linkgit:git-gui[1]. "75" is the default.
1227
1228gui.diffcontext::
1229        Specifies how many context lines should be used in calls to diff
1230        made by the linkgit:git-gui[1]. The default is "5".
1231
1232gui.encoding::
1233        Specifies the default encoding to use for displaying of
1234        file contents in linkgit:git-gui[1] and linkgit:gitk[1].
1235        It can be overridden by setting the 'encoding' attribute
1236        for relevant files (see linkgit:gitattributes[5]).
1237        If this option is not set, the tools default to the
1238        locale encoding.
1239
1240gui.matchtrackingbranch::
1241        Determines if new branches created with linkgit:git-gui[1] should
1242        default to tracking remote branches with matching names or
1243        not. Default: "false".
1244
1245gui.newbranchtemplate::
1246        Is used as suggested name when creating new branches using the
1247        linkgit:git-gui[1].
1248
1249gui.pruneduringfetch::
1250        "true" if linkgit:git-gui[1] should prune remote-tracking branches when
1251        performing a fetch. The default value is "false".
1252
1253gui.trustmtime::
1254        Determines if linkgit:git-gui[1] should trust the file modification
1255        timestamp or not. By default the timestamps are not trusted.
1256
1257gui.spellingdictionary::
1258        Specifies the dictionary used for spell checking commit messages in
1259        the linkgit:git-gui[1]. When set to "none" spell checking is turned
1260        off.
1261
1262gui.fastcopyblame::
1263        If true, 'git gui blame' uses `-C` instead of `-C -C` for original
1264        location detection. It makes blame significantly faster on huge
1265        repositories at the expense of less thorough copy detection.
1266
1267gui.copyblamethreshold::
1268        Specifies the threshold to use in 'git gui blame' original location
1269        detection, measured in alphanumeric characters. See the
1270        linkgit:git-blame[1] manual for more information on copy detection.
1271
1272gui.blamehistoryctx::
1273        Specifies the radius of history context in days to show in
1274        linkgit:gitk[1] for the selected commit, when the `Show History
1275        Context` menu item is invoked from 'git gui blame'. If this
1276        variable is set to zero, the whole history is shown.
1277
1278guitool.<name>.cmd::
1279        Specifies the shell command line to execute when the corresponding item
1280        of the linkgit:git-gui[1] `Tools` menu is invoked. This option is
1281        mandatory for every tool. The command is executed from the root of
1282        the working directory, and in the environment it receives the name of
1283        the tool as 'GIT_GUITOOL', the name of the currently selected file as
1284        'FILENAME', and the name of the current branch as 'CUR_BRANCH' (if
1285        the head is detached, 'CUR_BRANCH' is empty).
1286
1287guitool.<name>.needsfile::
1288        Run the tool only if a diff is selected in the GUI. It guarantees
1289        that 'FILENAME' is not empty.
1290
1291guitool.<name>.noconsole::
1292        Run the command silently, without creating a window to display its
1293        output.
1294
1295guitool.<name>.norescan::
1296        Don't rescan the working directory for changes after the tool
1297        finishes execution.
1298
1299guitool.<name>.confirm::
1300        Show a confirmation dialog before actually running the tool.
1301
1302guitool.<name>.argprompt::
1303        Request a string argument from the user, and pass it to the tool
1304        through the 'ARGS' environment variable. Since requesting an
1305        argument implies confirmation, the 'confirm' option has no effect
1306        if this is enabled. If the option is set to 'true', 'yes', or '1',
1307        the dialog uses a built-in generic prompt; otherwise the exact
1308        value of the variable is used.
1309
1310guitool.<name>.revprompt::
1311        Request a single valid revision from the user, and set the
1312        'REVISION' environment variable. In other aspects this option
1313        is similar to 'argprompt', and can be used together with it.
1314
1315guitool.<name>.revunmerged::
1316        Show only unmerged branches in the 'revprompt' subdialog.
1317        This is useful for tools similar to merge or rebase, but not
1318        for things like checkout or reset.
1319
1320guitool.<name>.title::
1321        Specifies the title to use for the prompt dialog. The default
1322        is the tool name.
1323
1324guitool.<name>.prompt::
1325        Specifies the general prompt string to display at the top of
1326        the dialog, before subsections for 'argprompt' and 'revprompt'.
1327        The default value includes the actual command.
1328
1329help.browser::
1330        Specify the browser that will be used to display help in the
1331        'web' format. See linkgit:git-help[1].
1332
1333help.format::
1334        Override the default help format used by linkgit:git-help[1].
1335        Values 'man', 'info', 'web' and 'html' are supported. 'man' is
1336        the default. 'web' and 'html' are the same.
1337
1338help.autocorrect::
1339        Automatically correct and execute mistyped commands after
1340        waiting for the given number of deciseconds (0.1 sec). If more
1341        than one command can be deduced from the entered text, nothing
1342        will be executed.  If the value of this option is negative,
1343        the corrected command will be executed immediately. If the
1344        value is 0 - the command will be just shown but not executed.
1345        This is the default.
1346
1347http.proxy::
1348        Override the HTTP proxy, normally configured using the 'http_proxy',
1349        'https_proxy', and 'all_proxy' environment variables (see
1350        `curl(1)`).  This can be overridden on a per-remote basis; see
1351        remote.<name>.proxy
1352
1353http.cookiefile::
1354        File containing previously stored cookie lines which should be used
1355        in the git http session, if they match the server. The file format
1356        of the file to read cookies from should be plain HTTP headers or
1357        the Netscape/Mozilla cookie file format (see linkgit:curl[1]).
1358        NOTE that the file specified with http.cookiefile is only used as
1359        input. No cookies will be stored in the file.
1360
1361http.sslVerify::
1362        Whether to verify the SSL certificate when fetching or pushing
1363        over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
1364        variable.
1365
1366http.sslCert::
1367        File containing the SSL certificate when fetching or pushing
1368        over HTTPS. Can be overridden by the 'GIT_SSL_CERT' environment
1369        variable.
1370
1371http.sslKey::
1372        File containing the SSL private key when fetching or pushing
1373        over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment
1374        variable.
1375
1376http.sslCertPasswordProtected::
1377        Enable git's password prompt for the SSL certificate.  Otherwise
1378        OpenSSL will prompt the user, possibly many times, if the
1379        certificate or private key is encrypted.  Can be overridden by the
1380        'GIT_SSL_CERT_PASSWORD_PROTECTED' environment variable.
1381
1382http.sslCAInfo::
1383        File containing the certificates to verify the peer with when
1384        fetching or pushing over HTTPS. Can be overridden by the
1385        'GIT_SSL_CAINFO' environment variable.
1386
1387http.sslCAPath::
1388        Path containing files with the CA certificates to verify the peer
1389        with when fetching or pushing over HTTPS. Can be overridden
1390        by the 'GIT_SSL_CAPATH' environment variable.
1391
1392http.maxRequests::
1393        How many HTTP requests to launch in parallel. Can be overridden
1394        by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5.
1395
1396http.minSessions::
1397        The number of curl sessions (counted across slots) to be kept across
1398        requests. They will not be ended with curl_easy_cleanup() until
1399        http_cleanup() is invoked. If USE_CURL_MULTI is not defined, this
1400        value will be capped at 1. Defaults to 1.
1401
1402http.postBuffer::
1403        Maximum size in bytes of the buffer used by smart HTTP
1404        transports when POSTing data to the remote system.
1405        For requests larger than this buffer size, HTTP/1.1 and
1406        Transfer-Encoding: chunked is used to avoid creating a
1407        massive pack file locally.  Default is 1 MiB, which is
1408        sufficient for most requests.
1409
1410http.lowSpeedLimit, http.lowSpeedTime::
1411        If the HTTP transfer speed is less than 'http.lowSpeedLimit'
1412        for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
1413        Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and
1414        'GIT_HTTP_LOW_SPEED_TIME' environment variables.
1415
1416http.noEPSV::
1417        A boolean which disables using of EPSV ftp command by curl.
1418        This can helpful with some "poor" ftp servers which don't
1419        support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
1420        environment variable. Default is false (curl will use EPSV).
1421
1422http.useragent::
1423        The HTTP USER_AGENT string presented to an HTTP server.  The default
1424        value represents the version of the client git such as git/1.7.1.
1425        This option allows you to override this value to a more common value
1426        such as Mozilla/4.0.  This may be necessary, for instance, if
1427        connecting through a firewall that restricts HTTP connections to a set
1428        of common USER_AGENT strings (but not including those like git/1.7.1).
1429        Can be overridden by the 'GIT_HTTP_USER_AGENT' environment variable.
1430
1431i18n.commitEncoding::
1432        Character encoding the commit messages are stored in; git itself
1433        does not care per se, but this information is necessary e.g. when
1434        importing commits from emails or in the gitk graphical history
1435        browser (and possibly at other places in the future or in other
1436        porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.
1437
1438i18n.logOutputEncoding::
1439        Character encoding the commit messages are converted to when
1440        running 'git log' and friends.
1441
1442imap::
1443        The configuration variables in the 'imap' section are described
1444        in linkgit:git-imap-send[1].
1445
1446init.templatedir::
1447        Specify the directory from which templates will be copied.
1448        (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].)
1449
1450instaweb.browser::
1451        Specify the program that will be used to browse your working
1452        repository in gitweb. See linkgit:git-instaweb[1].
1453
1454instaweb.httpd::
1455        The HTTP daemon command-line to start gitweb on your working
1456        repository. See linkgit:git-instaweb[1].
1457
1458instaweb.local::
1459        If true the web server started by linkgit:git-instaweb[1] will
1460        be bound to the local IP (127.0.0.1).
1461
1462instaweb.modulepath::
1463        The default module path for linkgit:git-instaweb[1] to use
1464        instead of /usr/lib/apache2/modules.  Only used if httpd
1465        is Apache.
1466
1467instaweb.port::
1468        The port number to bind the gitweb httpd to. See
1469        linkgit:git-instaweb[1].
1470
1471interactive.singlekey::
1472        In interactive commands, allow the user to provide one-letter
1473        input with a single key (i.e., without hitting enter).
1474        Currently this is used by the `--patch` mode of
1475        linkgit:git-add[1], linkgit:git-checkout[1], linkgit:git-commit[1],
1476        linkgit:git-reset[1], and linkgit:git-stash[1]. Note that this
1477        setting is silently ignored if portable keystroke input
1478        is not available.
1479
1480log.abbrevCommit::
1481        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
1482        linkgit:git-whatchanged[1] assume `--abbrev-commit`. You may
1483        override this option with `--no-abbrev-commit`.
1484
1485log.date::
1486        Set the default date-time mode for the 'log' command.
1487        Setting a value for log.date is similar to using 'git log''s
1488        `--date` option.  Possible values are `relative`, `local`,
1489        `default`, `iso`, `rfc`, and `short`; see linkgit:git-log[1]
1490        for details.
1491
1492log.decorate::
1493        Print out the ref names of any commits that are shown by the log
1494        command. If 'short' is specified, the ref name prefixes 'refs/heads/',
1495        'refs/tags/' and 'refs/remotes/' will not be printed. If 'full' is
1496        specified, the full ref name (including prefix) will be printed.
1497        This is the same as the log commands '--decorate' option.
1498
1499log.showroot::
1500        If true, the initial commit will be shown as a big creation event.
1501        This is equivalent to a diff against an empty tree.
1502        Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
1503        normally hide the root commit will now show it. True by default.
1504
1505mailmap.file::
1506        The location of an augmenting mailmap file. The default
1507        mailmap, located in the root of the repository, is loaded
1508        first, then the mailmap file pointed to by this variable.
1509        The location of the mailmap file may be in a repository
1510        subdirectory, or somewhere outside of the repository itself.
1511        See linkgit:git-shortlog[1] and linkgit:git-blame[1].
1512
1513man.viewer::
1514        Specify the programs that may be used to display help in the
1515        'man' format. See linkgit:git-help[1].
1516
1517man.<tool>.cmd::
1518        Specify the command to invoke the specified man viewer. The
1519        specified command is evaluated in shell with the man page
1520        passed as argument. (See linkgit:git-help[1].)
1521
1522man.<tool>.path::
1523        Override the path for the given tool that may be used to
1524        display help in the 'man' format. See linkgit:git-help[1].
1525
1526include::merge-config.txt[]
1527
1528mergetool.<tool>.path::
1529        Override the path for the given tool.  This is useful in case
1530        your tool is not in the PATH.
1531
1532mergetool.<tool>.cmd::
1533        Specify the command to invoke the specified merge tool.  The
1534        specified command is evaluated in shell with the following
1535        variables available: 'BASE' is the name of a temporary file
1536        containing the common base of the files to be merged, if available;
1537        'LOCAL' is the name of a temporary file containing the contents of
1538        the file on the current branch; 'REMOTE' is the name of a temporary
1539        file containing the contents of the file from the branch being
1540        merged; 'MERGED' contains the name of the file to which the merge
1541        tool should write the results of a successful merge.
1542
1543mergetool.<tool>.trustExitCode::
1544        For a custom merge command, specify whether the exit code of
1545        the merge command can be used to determine whether the merge was
1546        successful.  If this is not set to true then the merge target file
1547        timestamp is checked and the merge assumed to have been successful
1548        if the file has been updated, otherwise the user is prompted to
1549        indicate the success of the merge.
1550
1551mergetool.keepBackup::
1552        After performing a merge, the original file with conflict markers
1553        can be saved as a file with a `.orig` extension.  If this variable
1554        is set to `false` then this file is not preserved.  Defaults to
1555        `true` (i.e. keep the backup files).
1556
1557mergetool.keepTemporaries::
1558        When invoking a custom merge tool, git uses a set of temporary
1559        files to pass to the tool. If the tool returns an error and this
1560        variable is set to `true`, then these temporary files will be
1561        preserved, otherwise they will be removed after the tool has
1562        exited. Defaults to `false`.
1563
1564mergetool.prompt::
1565        Prompt before each invocation of the merge resolution program.
1566
1567notes.displayRef::
1568        The (fully qualified) refname from which to show notes when
1569        showing commit messages.  The value of this variable can be set
1570        to a glob, in which case notes from all matching refs will be
1571        shown.  You may also specify this configuration variable
1572        several times.  A warning will be issued for refs that do not
1573        exist, but a glob that does not match any refs is silently
1574        ignored.
1575+
1576This setting can be overridden with the `GIT_NOTES_DISPLAY_REF`
1577environment variable, which must be a colon separated list of refs or
1578globs.
1579+
1580The effective value of "core.notesRef" (possibly overridden by
1581GIT_NOTES_REF) is also implicitly added to the list of refs to be
1582displayed.
1583
1584notes.rewrite.<command>::
1585        When rewriting commits with <command> (currently `amend` or
1586        `rebase`) and this variable is set to `true`, git
1587        automatically copies your notes from the original to the
1588        rewritten commit.  Defaults to `true`, but see
1589        "notes.rewriteRef" below.
1590
1591notes.rewriteMode::
1592        When copying notes during a rewrite (see the
1593        "notes.rewrite.<command>" option), determines what to do if
1594        the target commit already has a note.  Must be one of
1595        `overwrite`, `concatenate`, or `ignore`.  Defaults to
1596        `concatenate`.
1597+
1598This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
1599environment variable.
1600
1601notes.rewriteRef::
1602        When copying notes during a rewrite, specifies the (fully
1603        qualified) ref whose notes should be copied.  The ref may be a
1604        glob, in which case notes in all matching refs will be copied.
1605        You may also specify this configuration several times.
1606+
1607Does not have a default value; you must configure this variable to
1608enable note rewriting.  Set it to `refs/notes/commits` to enable
1609rewriting for the default commit notes.
1610+
1611This setting can be overridden with the `GIT_NOTES_REWRITE_REF`
1612environment variable, which must be a colon separated list of refs or
1613globs.
1614
1615pack.window::
1616        The size of the window used by linkgit:git-pack-objects[1] when no
1617        window size is given on the command line. Defaults to 10.
1618
1619pack.depth::
1620        The maximum delta depth used by linkgit:git-pack-objects[1] when no
1621        maximum depth is given on the command line. Defaults to 50.
1622
1623pack.windowMemory::
1624        The window memory size limit used by linkgit:git-pack-objects[1]
1625        when no limit is given on the command line.  The value can be
1626        suffixed with "k", "m", or "g".  Defaults to 0, meaning no
1627        limit.
1628
1629pack.compression::
1630        An integer -1..9, indicating the compression level for objects
1631        in a pack file. -1 is the zlib default. 0 means no
1632        compression, and 1..9 are various speed/size tradeoffs, 9 being
1633        slowest.  If not set,  defaults to core.compression.  If that is
1634        not set,  defaults to -1, the zlib default, which is "a default
1635        compromise between speed and compression (currently equivalent
1636        to level 6)."
1637+
1638Note that changing the compression level will not automatically recompress
1639all existing objects. You can force recompression by passing the -F option
1640to linkgit:git-repack[1].
1641
1642pack.deltaCacheSize::
1643        The maximum memory in bytes used for caching deltas in
1644        linkgit:git-pack-objects[1] before writing them out to a pack.
1645        This cache is used to speed up the writing object phase by not
1646        having to recompute the final delta result once the best match
1647        for all objects is found.  Repacking large repositories on machines
1648        which are tight with memory might be badly impacted by this though,
1649        especially if this cache pushes the system into swapping.
1650        A value of 0 means no limit. The smallest size of 1 byte may be
1651        used to virtually disable this cache. Defaults to 256 MiB.
1652
1653pack.deltaCacheLimit::
1654        The maximum size of a delta, that is cached in
1655        linkgit:git-pack-objects[1]. This cache is used to speed up the
1656        writing object phase by not having to recompute the final delta
1657        result once the best match for all objects is found. Defaults to 1000.
1658
1659pack.threads::
1660        Specifies the number of threads to spawn when searching for best
1661        delta matches.  This requires that linkgit:git-pack-objects[1]
1662        be compiled with pthreads otherwise this option is ignored with a
1663        warning. This is meant to reduce packing time on multiprocessor
1664        machines. The required amount of memory for the delta search window
1665        is however multiplied by the number of threads.
1666        Specifying 0 will cause git to auto-detect the number of CPU's
1667        and set the number of threads accordingly.
1668
1669pack.indexVersion::
1670        Specify the default pack index version.  Valid values are 1 for
1671        legacy pack index used by Git versions prior to 1.5.2, and 2 for
1672        the new pack index with capabilities for packs larger than 4 GB
1673        as well as proper protection against the repacking of corrupted
1674        packs.  Version 2 is the default.  Note that version 2 is enforced
1675        and this config option ignored whenever the corresponding pack is
1676        larger than 2 GB.
1677+
1678If you have an old git that does not understand the version 2 `*.idx` file,
1679cloning or fetching over a non native protocol (e.g. "http" and "rsync")
1680that will copy both `*.pack` file and corresponding `*.idx` file from the
1681other side may give you a repository that cannot be accessed with your
1682older version of git. If the `*.pack` file is smaller than 2 GB, however,
1683you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
1684the `*.idx` file.
1685
1686pack.packSizeLimit::
1687        The maximum size of a pack.  This setting only affects
1688        packing to a file when repacking, i.e. the git:// protocol
1689        is unaffected.  It can be overridden by the `--max-pack-size`
1690        option of linkgit:git-repack[1]. The minimum size allowed is
1691        limited to 1 MiB. The default is unlimited.
1692        Common unit suffixes of 'k', 'm', or 'g' are
1693        supported.
1694
1695pager.<cmd>::
1696        If the value is boolean, turns on or off pagination of the
1697        output of a particular git subcommand when writing to a tty.
1698        Otherwise, turns on pagination for the subcommand using the
1699        pager specified by the value of `pager.<cmd>`.  If `--paginate`
1700        or `--no-pager` is specified on the command line, it takes
1701        precedence over this option.  To disable pagination for all
1702        commands, set `core.pager` or `GIT_PAGER` to `cat`.
1703
1704pretty.<name>::
1705        Alias for a --pretty= format string, as specified in
1706        linkgit:git-log[1]. Any aliases defined here can be used just
1707        as the built-in pretty formats could. For example,
1708        running `git config pretty.changelog "format:* %H %s"`
1709        would cause the invocation `git log --pretty=changelog`
1710        to be equivalent to running `git log "--pretty=format:* %H %s"`.
1711        Note that an alias with the same name as a built-in format
1712        will be silently ignored.
1713
1714pull.rebase::
1715        When true, rebase branches on top of the fetched branch, instead
1716        of merging the default branch from the default remote when "git
1717        pull" is run. See "branch.<name>.rebase" for setting this on a
1718        per-branch basis.
1719+
1720*NOTE*: this is a possibly dangerous operation; do *not* use
1721it unless you understand the implications (see linkgit:git-rebase[1]
1722for details).
1723
1724pull.octopus::
1725        The default merge strategy to use when pulling multiple branches
1726        at once.
1727
1728pull.twohead::
1729        The default merge strategy to use when pulling a single branch.
1730
1731push.default::
1732        Defines the action git push should take if no refspec is given
1733        on the command line, no refspec is configured in the remote, and
1734        no refspec is implied by any of the options given on the command
1735        line. Possible values are:
1736+
1737--
1738* `nothing` - do not push anything.
1739* `matching` - push all branches having the same name in both ends.
1740  This is for those who prepare all the branches into a publishable
1741  shape and then push them out with a single command.  It is not
1742  appropriate for pushing into a repository shared by multiple users,
1743  since locally stalled branches will attempt a non-fast forward push
1744  if other users updated the branch.
1745  +
1746  This is currently the default, but Git 2.0 will change the default
1747  to `simple`.
1748* `upstream` - push the current branch to its upstream branch.
1749  With this, `git push` will update the same remote ref as the one which
1750  is merged by `git pull`, making `push` and `pull` symmetrical.
1751  See "branch.<name>.merge" for how to configure the upstream branch.
1752* `simple` - like `upstream`, but refuses to push if the upstream
1753  branch's name is different from the local one. This is the safest
1754  option and is well-suited for beginners. It will become the default
1755  in Git 2.0.
1756* `current` - push the current branch to a branch of the same name.
1757--
1758+
1759The `simple`, `current` and `upstream` modes are for those who want to
1760push out a single branch after finishing work, even when the other
1761branches are not yet ready to be pushed out. If you are working with
1762other people to push into the same shared repository, you would want
1763to use one of these.
1764
1765rebase.stat::
1766        Whether to show a diffstat of what changed upstream since the last
1767        rebase. False by default.
1768
1769rebase.autosquash::
1770        If set to true enable '--autosquash' option by default.
1771
1772receive.autogc::
1773        By default, git-receive-pack will run "git-gc --auto" after
1774        receiving data from git-push and updating refs.  You can stop
1775        it by setting this variable to false.
1776
1777receive.fsckObjects::
1778        If it is set to true, git-receive-pack will check all received
1779        objects. It will abort in the case of a malformed object or a
1780        broken link. The result of an abort are only dangling objects.
1781        Defaults to false. If not set, the value of `transfer.fsckObjects`
1782        is used instead.
1783
1784receive.unpackLimit::
1785        If the number of objects received in a push is below this
1786        limit then the objects will be unpacked into loose object
1787        files. However if the number of received objects equals or
1788        exceeds this limit then the received pack will be stored as
1789        a pack, after adding any missing delta bases.  Storing the
1790        pack from a push can make the push operation complete faster,
1791        especially on slow filesystems.  If not set, the value of
1792        `transfer.unpackLimit` is used instead.
1793
1794receive.denyDeletes::
1795        If set to true, git-receive-pack will deny a ref update that deletes
1796        the ref. Use this to prevent such a ref deletion via a push.
1797
1798receive.denyDeleteCurrent::
1799        If set to true, git-receive-pack will deny a ref update that
1800        deletes the currently checked out branch of a non-bare repository.
1801
1802receive.denyCurrentBranch::
1803        If set to true or "refuse", git-receive-pack will deny a ref update
1804        to the currently checked out branch of a non-bare repository.
1805        Such a push is potentially dangerous because it brings the HEAD
1806        out of sync with the index and working tree. If set to "warn",
1807        print a warning of such a push to stderr, but allow the push to
1808        proceed. If set to false or "ignore", allow such pushes with no
1809        message. Defaults to "refuse".
1810
1811receive.denyNonFastForwards::
1812        If set to true, git-receive-pack will deny a ref update which is
1813        not a fast-forward. Use this to prevent such an update via a push,
1814        even if that push is forced. This configuration variable is
1815        set when initializing a shared repository.
1816
1817receive.updateserverinfo::
1818        If set to true, git-receive-pack will run git-update-server-info
1819        after receiving data from git-push and updating refs.
1820
1821remote.<name>.url::
1822        The URL of a remote repository.  See linkgit:git-fetch[1] or
1823        linkgit:git-push[1].
1824
1825remote.<name>.pushurl::
1826        The push URL of a remote repository.  See linkgit:git-push[1].
1827
1828remote.<name>.proxy::
1829        For remotes that require curl (http, https and ftp), the URL to
1830        the proxy to use for that remote.  Set to the empty string to
1831        disable proxying for that remote.
1832
1833remote.<name>.fetch::
1834        The default set of "refspec" for linkgit:git-fetch[1]. See
1835        linkgit:git-fetch[1].
1836
1837remote.<name>.push::
1838        The default set of "refspec" for linkgit:git-push[1]. See
1839        linkgit:git-push[1].
1840
1841remote.<name>.mirror::
1842        If true, pushing to this remote will automatically behave
1843        as if the `--mirror` option was given on the command line.
1844
1845remote.<name>.skipDefaultUpdate::
1846        If true, this remote will be skipped by default when updating
1847        using linkgit:git-fetch[1] or the `update` subcommand of
1848        linkgit:git-remote[1].
1849
1850remote.<name>.skipFetchAll::
1851        If true, this remote will be skipped by default when updating
1852        using linkgit:git-fetch[1] or the `update` subcommand of
1853        linkgit:git-remote[1].
1854
1855remote.<name>.receivepack::
1856        The default program to execute on the remote side when pushing.  See
1857        option \--receive-pack of linkgit:git-push[1].
1858
1859remote.<name>.uploadpack::
1860        The default program to execute on the remote side when fetching.  See
1861        option \--upload-pack of linkgit:git-fetch-pack[1].
1862
1863remote.<name>.tagopt::
1864        Setting this value to \--no-tags disables automatic tag following when
1865        fetching from remote <name>. Setting it to \--tags will fetch every
1866        tag from remote <name>, even if they are not reachable from remote
1867        branch heads. Passing these flags directly to linkgit:git-fetch[1] can
1868        override this setting. See options \--tags and \--no-tags of
1869        linkgit:git-fetch[1].
1870
1871remote.<name>.vcs::
1872        Setting this to a value <vcs> will cause git to interact with
1873        the remote with the git-remote-<vcs> helper.
1874
1875remotes.<group>::
1876        The list of remotes which are fetched by "git remote update
1877        <group>".  See linkgit:git-remote[1].
1878
1879repack.usedeltabaseoffset::
1880        By default, linkgit:git-repack[1] creates packs that use
1881        delta-base offset. If you need to share your repository with
1882        git older than version 1.4.4, either directly or via a dumb
1883        protocol such as http, then you need to set this option to
1884        "false" and repack. Access from old git versions over the
1885        native protocol are unaffected by this option.
1886
1887rerere.autoupdate::
1888        When set to true, `git-rerere` updates the index with the
1889        resulting contents after it cleanly resolves conflicts using
1890        previously recorded resolution.  Defaults to false.
1891
1892rerere.enabled::
1893        Activate recording of resolved conflicts, so that identical
1894        conflict hunks can be resolved automatically, should they be
1895        encountered again.  By default, linkgit:git-rerere[1] is
1896        enabled if there is an `rr-cache` directory under the
1897        `$GIT_DIR`, e.g. if "rerere" was previously used in the
1898        repository.
1899
1900sendemail.identity::
1901        A configuration identity. When given, causes values in the
1902        'sendemail.<identity>' subsection to take precedence over
1903        values in the 'sendemail' section. The default identity is
1904        the value of 'sendemail.identity'.
1905
1906sendemail.smtpencryption::
1907        See linkgit:git-send-email[1] for description.  Note that this
1908        setting is not subject to the 'identity' mechanism.
1909
1910sendemail.smtpssl::
1911        Deprecated alias for 'sendemail.smtpencryption = ssl'.
1912
1913sendemail.<identity>.*::
1914        Identity-specific versions of the 'sendemail.*' parameters
1915        found below, taking precedence over those when the this
1916        identity is selected, through command-line or
1917        'sendemail.identity'.
1918
1919sendemail.aliasesfile::

1943sendemail.signedoffcc::
1944        Deprecated alias for 'sendemail.signedoffbycc'.
1945
1946showbranch.default::
1947        The default set of branches for linkgit:git-show-branch[1].
1948        See linkgit:git-show-branch[1].
1949
1950status.relativePaths::
1951        By default, linkgit:git-status[1] shows paths relative to the
1952        current directory. Setting this variable to `false` shows paths
1953        relative to the repository root (this was the default for git
1954        prior to v1.5.4).
1955
1956status.showUntrackedFiles::
1957        By default, linkgit:git-status[1] and linkgit:git-commit[1] show
1958        files which are not currently tracked by Git. Directories which
1959        contain only untracked files, are shown with the directory name
1960        only. Showing untracked files means that Git needs to lstat() all
1961        all the files in the whole repository, which might be slow on some
1962        systems. So, this variable controls how the commands displays
1963        the untracked files. Possible values are:
1964+
1965--
1966* `no` - Show no untracked files.
1967* `normal` - Show untracked files and directories.
1968* `all` - Show also individual files in untracked directories.
1969--
1970+
1971If this variable is not specified, it defaults to 'normal'.
1972This variable can be overridden with the -u|--untracked-files option
1973of linkgit:git-status[1] and linkgit:git-commit[1].
1974
1975status.submodulesummary::
1976        Defaults to false.
1977        If this is set to a non zero number or true (identical to -1 or an
1978        unlimited number), the submodule summary will be enabled and a
1979        summary of commits for modified submodules will be shown (see
1980        --summary-limit option of linkgit:git-submodule[1]).
1981
1982submodule.<name>.path::
1983submodule.<name>.url::
1984submodule.<name>.update::
1985        The path within this project, URL, and the updating strategy
1986        for a submodule.  These variables are initially populated
1987        by 'git submodule init'; edit them to override the
1988        URL and other values found in the `.gitmodules` file.  See
1989        linkgit:git-submodule[1] and linkgit:gitmodules[5] for details.
1990
1991submodule.<name>.fetchRecurseSubmodules::
1992        This option can be used to control recursive fetching of this
1993        submodule. It can be overridden by using the --[no-]recurse-submodules
1994        command line option to "git fetch" and "git pull".
1995        This setting will override that from in the linkgit:gitmodules[5]
1996        file.
1997
1998submodule.<name>.ignore::
1999        Defines under what circumstances "git status" and the diff family show
2000        a submodule as modified. When set to "all", it will never be considered
2001        modified, "dirty" will ignore all changes to the submodules work tree and
2002        takes only differences between the HEAD of the submodule and the commit
2003        recorded in the superproject into account. "untracked" will additionally
2004        let submodules with modified tracked files in their work tree show up.
2005        Using "none" (the default when this option is not set) also shows
2006        submodules that have untracked files in their work tree as changed.
2007        This setting overrides any setting made in .gitmodules for this submodule,
2008        both settings can be overridden on the command line by using the
2009        "--ignore-submodules" option.

2011tar.umask::
2012        This variable can be used to restrict the permission bits of
2013        tar archive entries.  The default is 0002, which turns off the
2014        world write bit.  The special value "user" indicates that the
2015        archiving user's umask will be used instead.  See umask(2) and
2016        linkgit:git-archive[1].
2017
2018transfer.fsckObjects::
2019        When `fetch.fsckObjects` or `receive.fsckObjects` are
2020        not set, the value of this variable is used instead.
2021        Defaults to false.
2022
2023transfer.unpackLimit::
2024        When `fetch.unpackLimit` or `receive.unpackLimit` are
2025        not set, the value of this variable is used instead.
2026        The default value is 100.
2027
2028url.<base>.insteadOf::
2029        Any URL that starts with this value will be rewritten to
2030        start, instead, with <base>. In cases where some site serves a
2031        large number of repositories, and serves them with multiple
2032        access methods, and some users need to use different access
2033        methods, this feature allows people to specify any of the
2034        equivalent URLs and have git automatically rewrite the URL to
2035        the best alternative for the particular user, even for a
2036        never-before-seen repository on the site.  When more than one
2037        insteadOf strings match a given URL, the longest match is used.
2038
2039url.<base>.pushInsteadOf::
2040        Any URL that starts with this value will not be pushed to;
2041        instead, it will be rewritten to start with <base>, and the
2042        resulting URL will be pushed to. In cases where some site serves
2043        a large number of repositories, and serves them with multiple
2044        access methods, some of which do not allow push, this feature
2045        allows people to specify a pull-only URL and have git
2046        automatically use an appropriate URL to push, even for a
2047        never-before-seen repository on the site.  When more than one
2048        pushInsteadOf strings match a given URL, the longest match is
2049        used.  If a remote has an explicit pushurl, git will ignore this
2050        setting for that remote.
2051
2052user.email::
2053        Your email address to be recorded in any newly created commits.
2054        Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and
2055        'EMAIL' environment variables.  See linkgit:git-commit-tree[1].
2056
2057user.name::
2058        Your full name to be recorded in any newly created commits.
2059        Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
2060        environment variables.  See linkgit:git-commit-tree[1].
2061
2062user.signingkey::
2063        If linkgit:git-tag[1] is not selecting the key you want it to
2064        automatically when creating a signed tag, you can override the
2065        default selection with this variable.  This option is passed
2066        unchanged to gpg's --local-user parameter, so you may specify a key
2067        using any method that gpg supports.
2068
2069web.browser::
2070        Specify a web browser that may be used by some commands.
2071        Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
2072        may use it.
