   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 and only alphanumeric
  16characters are allowed. Some variables may appear multiple times.
  17
  18Syntax
  19~~~~~~
  20
  21The syntax is fairly flexible and permissive; whitespaces are mostly
  22ignored.  The '#' and ';' characters begin comments to the end of line,
  23blank lines are ignored.
  24
  25The file consists of sections and variables.  A section begins with
  26the name of the section in square brackets and continues until the next
  27section begins.  Section names are not case sensitive.  Only alphanumeric
  28characters, `-` and `.` are allowed in section names.  Each variable
  29must belong to some section, which means that there must be a section
  30header before the first setting of a variable.
  31
  32Sections can be further divided into subsections.  To begin a subsection
  33put its name in double quotes, separated by space from the section name,
  34in the section header, like in the example below:
  35
  36--------
  37        [section "subsection"]
  38
  39--------
  40
  41Subsection names are case sensitive and can contain any characters except
  42newline (doublequote `"` and backslash have to be escaped as `\"` and `\\`,
  43respectively).  Section headers cannot span multiple
  44lines.  Variables may belong directly to a section or to a given subsection.
  45You can have `[section]` if you have `[section "subsection"]`, but you
  46don't need to.
  47
  48There is also a case insensitive alternative `[section.subsection]` syntax.
  49In this syntax, subsection names follow the same restrictions as for section
  50names.
  51
  52All the other lines are recognized as setting variables, in the form
  53'name = value'.  If there is no equal sign on the line, the entire line
  54is taken as 'name' and the variable is recognized as boolean "true".
  55The variable names are case-insensitive and only alphanumeric
  56characters and `-` are allowed.  There can be more than one value
  57for a given variable; we say then that variable is multivalued.
  58
  59Leading and trailing whitespace in a variable value is discarded.
  60Internal whitespace within a variable value is retained verbatim.
  61
  62The values following the equals sign in variable assign are all either
  63a string, an integer, or a boolean.  Boolean values may be given as yes/no,
  640/1, true/false or on/off.  Case is not significant in boolean values, when
  65converting value to the canonical form using '--bool' type specifier;
  66'git-config' will ensure that the output is "true" or "false".
  67
  68String values may be entirely or partially enclosed in double quotes.
  69You need to enclose variable values in double quotes if you want to
  70preserve leading or trailing whitespace, or if the variable value contains
  71comment characters (i.e. it contains '#' or ';').
  72Double quote `"` and backslash `\` characters in variable values must
  73be escaped: use `\"` for `"` and `\\` for `\`.
  74
  75The following escape sequences (beside `\"` and `\\`) are recognized:
  76`\n` for newline character (NL), `\t` for horizontal tabulation (HT, TAB)
  77and `\b` for backspace (BS).  No other char escape sequence, nor octal
  78char sequences are valid.
  79
  80Variable values ending in a `\` are continued on the next line in the
  81customary UNIX fashion.
  82
  83Some variables may require a special value format.

 107Variables
 108~~~~~~~~~
 109
 110Note that this list is non-comprehensive and not necessarily complete.
 111For command-specific variables, you will find a more detailed description
 112in the appropriate manual page. You will find a description of non-core
 113porcelain configuration variables in the respective porcelain documentation.
 114
 115core.fileMode::
 116        If false, the executable bit differences between the index and
 117        the working copy are ignored; useful on broken filesystems like FAT.
 118        See linkgit:git-update-index[1]. True by default.
 119
 120core.ignoreCygwinFSTricks::
 121        This option is only used by Cygwin implementation of Git. If false,
 122        the Cygwin stat() and lstat() functions are used. This may be useful
 123        if your repository consists of a few separate directories joined in
 124        one hierarchy using Cygwin mount. If true, Git uses native Win32 API
 125        whenever it is possible and falls back to Cygwin functions only to
 126        handle symbol links. The native mode is more than twice faster than
 127        normal Cygwin l/stat() functions. True by default, unless core.filemode
 128        is true, in which case ignoreCygwinFSTricks is ignored as Cygwin's
 129        POSIX emulation is required to support core.filemode.
 130
 131core.trustctime::
 132        If false, the ctime differences between the index and the
 133        working copy are ignored; useful when the inode change time
 134        is regularly modified by something outside Git (file system
 135        crawlers and some backup systems).
 136        See linkgit:git-update-index[1]. True by default.
 137
 138core.quotepath::
 139        The commands that output paths (e.g. 'ls-files',
 140        'diff'), when not given the `-z` option, will quote
 141        "unusual" characters in the pathname by enclosing the
 142        pathname in a double-quote pair and with backslashes the
 143        same way strings in C source code are quoted.  If this
 144        variable is set to false, the bytes higher than 0x80 are
 145        not quoted but output as verbatim.  Note that double
 146        quote, backslash and control characters are always
 147        quoted without `-z` regardless of the setting of this
 148        variable.
 149
 150core.autocrlf::
 151        If true, makes git convert `CRLF` at the end of lines in text files to
 152        `LF` when reading from the filesystem, and convert in reverse when
 153        writing to the filesystem.  The variable can be set to
 154        'input', in which case the conversion happens only while
 155        reading from the filesystem but files are written out with
 156        `LF` at the end of lines.  Currently, which paths to consider
 157        "text" (i.e. be subjected to the autocrlf mechanism) is
 158        decided purely based on the contents.
 159
 160core.safecrlf::
 161        If true, makes git check if converting `CRLF` as controlled by
 162        `core.autocrlf` is reversible.  Git will verify if a command
 163        modifies a file in the work tree either directly or indirectly.
 164        For example, committing a file followed by checking out the
 165        same file should yield the original file in the work tree.  If
 166        this is not the case for the current setting of
 167        `core.autocrlf`, git will reject the file.  The variable can
 168        be set to "warn", in which case git will only warn about an
 169        irreversible conversion but continue the operation.
 170+
 171CRLF conversion bears a slight chance of corrupting data.
 172autocrlf=true will convert CRLF to LF during commit and LF to
 173CRLF during checkout.  A file that contains a mixture of LF and
 174CRLF before the commit cannot be recreated by git.  For text
 175files this is the right thing to do: it corrects line endings
 176such that we have only LF line endings in the repository.
 177But for binary files that are accidentally classified as text the
 178conversion can corrupt data.
 179+
 180If you recognize such corruption early you can easily fix it by
 181setting the conversion type explicitly in .gitattributes.  Right
 182after committing you still have the original file in your work
 183tree and this file is not yet corrupted.  You can explicitly tell
 184git that this file is binary and git will handle the file
 185appropriately.
 186+
 187Unfortunately, the desired effect of cleaning up text files with
 188mixed line endings and the undesired effect of corrupting binary
 189files cannot be distinguished.  In both cases CRLFs are removed
 190in an irreversible way.  For text files this is the right thing
 191to do because CRLFs are line endings, while for binary files
 192converting CRLFs corrupts data.
 193+
 194Note, this safety check does not mean that a checkout will generate a
 195file identical to the original file for a different setting of
 196`core.autocrlf`, but only for the current one.  For example, a text
 197file with `LF` would be accepted with `core.autocrlf=input` and could
 198later be checked out with `core.autocrlf=true`, in which case the
 199resulting file would contain `CRLF`, although the original file
 200contained `LF`.  However, in both work trees the line endings would be
 201consistent, that is either all `LF` or all `CRLF`, but never mixed.  A
 202file with mixed line endings would be reported by the `core.safecrlf`
 203mechanism.
 204
 205core.symlinks::
 206        If false, symbolic links are checked out as small plain files that
 207        contain the link text. linkgit:git-update-index[1] and
 208        linkgit:git-add[1] will not change the recorded type to regular
 209        file. Useful on filesystems like FAT that do not support
 210        symbolic links. True by default.
 211
 212core.gitProxy::
 213        A "proxy command" to execute (as 'command host port') instead
 214        of establishing direct connection to the remote server when
 215        using the git protocol for fetching. If the variable value is
 216        in the "COMMAND for DOMAIN" format, the command is applied only
 217        on hostnames ending with the specified domain string. This variable
 218        may be set multiple times and is matched in the given order;
 219        the first match wins.
 220+
 221Can be overridden by the 'GIT_PROXY_COMMAND' environment variable
 222(which always applies universally, without the special "for"
 223handling).
 224+
 225The special string `none` can be used as the proxy command to
 226specify that no proxy be used for a given domain pattern.
 227This is useful for excluding servers inside a firewall from
 228proxy use, while defaulting to a common proxy for external domains.
 229
 230core.ignoreStat::
 231        If true, commands which modify both the working tree and the index
 232        will mark the updated paths with the "assume unchanged" bit in the
 233        index. These marked files are then assumed to stay unchanged in the
 234        working copy, until you mark them otherwise manually - Git will not
 235        detect the file changes by lstat() calls. This is useful on systems
 236        where those are very slow, such as Microsoft Windows.
 237        See linkgit:git-update-index[1].
 238        False by default.
 239
 240core.preferSymlinkRefs::
 241        Instead of the default "symref" format for HEAD
 242        and other symbolic reference files, use symbolic links.
 243        This is sometimes needed to work with old scripts that
 244        expect HEAD to be a symbolic link.
 245
 246core.bare::
 247        If true this repository is assumed to be 'bare' and has no
 248        working directory associated with it.  If this is the case a
 249        number of commands that require a working directory will be
 250        disabled, such as linkgit:git-add[1] or linkgit:git-merge[1].
 251+
 252This setting is automatically guessed by linkgit:git-clone[1] or
 253linkgit:git-init[1] when the repository was created.  By default a
 254repository that ends in "/.git" is assumed to be not bare (bare =
 255false), while all other repositories are assumed to be bare (bare
 256= true).
 257
 258core.worktree::
 259        Set the path to the working tree.  The value will not be
 260        used in combination with repositories found automatically in
 261        a .git directory (i.e. $GIT_DIR is not set).
 262        This can be overridden by the GIT_WORK_TREE environment
 263        variable and the '--work-tree' command line option. It can be
 264        a absolute path or relative path to the directory specified by
 265        --git-dir or GIT_DIR.
 266        Note: If --git-dir or GIT_DIR are specified but none of
 267        --work-tree, GIT_WORK_TREE and core.worktree is specified,
 268        the current working directory is regarded as the top directory
 269        of your working tree.
 270
 271core.logAllRefUpdates::
 272        Enable the reflog. Updates to a ref <ref> is logged to the file
 273        "$GIT_DIR/logs/<ref>", by appending the new and old
 274        SHA1, the date/time and the reason of the update, but
 275        only when the file exists.  If this configuration
 276        variable is set to true, missing "$GIT_DIR/logs/<ref>"
 277        file is automatically created for branch heads.
 278+
 279This information can be used to determine what commit
 280was the tip of a branch "2 days ago".
 281+
 282This value is true by default in a repository that has
 283a working directory associated with it, and false by
 284default in a bare repository.
 285
 286core.repositoryFormatVersion::
 287        Internal variable identifying the repository format and layout
 288        version.
 289
 290core.sharedRepository::
 291        When 'group' (or 'true'), the repository is made shareable between
 292        several users in a group (making sure all the files and objects are
 293        group-writable). When 'all' (or 'world' or 'everybody'), the
 294        repository will be readable by all users, additionally to being
 295        group-shareable. When 'umask' (or 'false'), git will use permissions
 296        reported by umask(2). When '0xxx', where '0xxx' is an octal number,
 297        files in the repository will have this mode value. '0xxx' will override
 298        user's umask value (whereas the other options will only override
 299        requested parts of the user's umask value). Examples: '0660' will make
 300        the repo read/write-able for the owner and group, but inaccessible to
 301        others (equivalent to 'group' unless umask is e.g. '0022'). '0640' is a
 302        repository that is group-readable but not group-writable.
 303        See linkgit:git-init[1]. False by default.
 304
 305core.warnAmbiguousRefs::
 306        If true, git will warn you if the ref name you passed it is ambiguous
 307        and might match multiple refs in the .git/refs/ tree. True by default.
 308
 309core.compression::
 310        An integer -1..9, indicating a default compression level.
 311        -1 is the zlib default. 0 means no compression,
 312        and 1..9 are various speed/size tradeoffs, 9 being slowest.
 313        If set, this provides a default to other compression variables,
 314        such as 'core.loosecompression' and 'pack.compression'.
 315
 316core.loosecompression::
 317        An integer -1..9, indicating the compression level for objects that
 318        are not in a pack file. -1 is the zlib default. 0 means no
 319        compression, and 1..9 are various speed/size tradeoffs, 9 being
 320        slowest.  If not set,  defaults to core.compression.  If that is
 321        not set,  defaults to 1 (best speed).
 322
 323core.packedGitWindowSize::
 324        Number of bytes of a pack file to map into memory in a
 325        single mapping operation.  Larger window sizes may allow
 326        your system to process a smaller number of large pack files
 327        more quickly.  Smaller window sizes will negatively affect
 328        performance due to increased calls to the operating system's
 329        memory manager, but may improve performance when accessing
 330        a large number of large pack files.
 331+
 332Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
 333MiB on 32 bit platforms and 1 GiB on 64 bit platforms.  This should
 334be reasonable for all users/operating systems.  You probably do
 335not need to adjust this value.
 336+
 337Common unit suffixes of 'k', 'm', or 'g' are supported.
 338
 339core.packedGitLimit::
 340        Maximum number of bytes to map simultaneously into memory
 341        from pack files.  If Git needs to access more than this many
 342        bytes at once to complete an operation it will unmap existing
 343        regions to reclaim virtual address space within the process.
 344+
 345Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms.
 346This should be reasonable for all users/operating systems, except on
 347the largest projects.  You probably do not need to adjust this value.
 348+
 349Common unit suffixes of 'k', 'm', or 'g' are supported.
 350
 351core.deltaBaseCacheLimit::
 352        Maximum number of bytes to reserve for caching base objects
 353        that multiple deltafied objects reference.  By storing the
 354        entire decompressed base objects in a cache Git is able
 355        to avoid unpacking and decompressing frequently used base
 356        objects multiple times.
 357+
 358Default is 16 MiB on all platforms.  This should be reasonable
 359for all users/operating systems, except on the largest projects.
 360You probably do not need to adjust this value.
 361+
 362Common unit suffixes of 'k', 'm', or 'g' are supported.
 363
 364core.excludesfile::
 365        In addition to '.gitignore' (per-directory) and
 366        '.git/info/exclude', git looks into this file for patterns
 367        of files which are not meant to be tracked.  See
 368        linkgit:gitignore[5].
 369
 370core.editor::
 371        Commands such as `commit` and `tag` that lets you edit
 372        messages by launching an editor uses the value of this
 373        variable when it is set, and the environment variable
 374        `GIT_EDITOR` is not set.  The order of preference is
 375        `GIT_EDITOR` environment, `core.editor`, `VISUAL` and
 376        `EDITOR` environment variables and then finally `vi`.
 377
 378core.pager::
 379        The command that git will use to paginate output.  Can
 380        be overridden with the `GIT_PAGER` environment
 381        variable.  Note that git sets the `LESS` environment
 382        variable to `FRSX` if it is unset when it runs the
 383        pager.  One can change these settings by setting the
 384        `LESS` variable to some other value.  Alternately,
 385        these settings can be overridden on a project or
 386        global basis by setting the `core.pager` option.
 387        Setting `core.pager` has no affect on the `LESS`
 388        environment variable behaviour above, so if you want
 389        to override git's default settings this way, you need
 390        to be explicit.  For example, to disable the S option
 391        in a backward compatible manner, set `core.pager`
 392        to `less -+$LESS -FRX`.  This will be passed to the
 393        shell by git, which will translate the final command to
 394        `LESS=FRSX less -+FRSX -FRX`.
 395
 396core.whitespace::
 397        A comma separated list of common whitespace problems to
 398        notice.  'git-diff' will use `color.diff.whitespace` to
 399        highlight them, and 'git-apply --whitespace=error' will
 400        consider them as errors.  You can prefix `-` to disable
 401        any of them (e.g. `-trailing-space`):
 402+
 403* `trailing-space` treats trailing whitespaces at the end of the line
 404  as an error (enabled by default).
 405* `space-before-tab` treats a space character that appears immediately
 406  before a tab character in the initial indent part of the line as an
 407  error (enabled by default).
 408* `indent-with-non-tab` treats a line that is indented with 8 or more
 409  space characters as an error (not enabled by default).
 410* `cr-at-eol` treats a carriage-return at the end of line as
 411  part of the line terminator, i.e. with it, `trailing-space`
 412  does not trigger if the character before such a carriage-return
 413  is not a whitespace (not enabled by default).
 414
 415core.fsyncobjectfiles::
 416        This boolean will enable 'fsync()' when writing object files.
 417+
 418This is a total waste of time and effort on a filesystem that orders
 419data writes properly, but can be useful for filesystems that do not use
 420journalling (traditional UNIX filesystems) or that only journal metadata
 421and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback").
 422
 423core.preloadindex::
 424        Enable parallel index preload for operations like 'git diff'
 425+
 426This can speed up operations like 'git diff' and 'git status' especially
 427on filesystems like NFS that have weak caching semantics and thus
 428relatively high IO latencies.  With this set to 'true', git will do the
 429index comparison to the filesystem data in parallel, allowing
 430overlapping IO's.
 431
 432core.createObject::
 433        You can set this to 'link', in which case a hardlink followed by
 434        a delete of the source are used to make sure that object creation
 435        will not overwrite existing objects.
 436+
 437On some file system/operating system combinations, this is unreliable.
 438Set this config setting to 'rename' there; However, This will remove the
 439check that makes sure that existing object files will not get overwritten.
 440
 441add.ignore-errors::
 442        Tells 'git-add' to continue adding files when some files cannot be
 443        added due to indexing errors. Equivalent to the '--ignore-errors'
 444        option of linkgit:git-add[1].
 445
 446alias.*::
 447        Command aliases for the linkgit:git[1] command wrapper - e.g.
 448        after defining "alias.last = cat-file commit HEAD", the invocation
 449        "git last" is equivalent to "git cat-file commit HEAD". To avoid
 450        confusion and troubles with script usage, aliases that
 451        hide existing git commands are ignored. Arguments are split by
 452        spaces, the usual shell quoting and escaping is supported.
 453        quote pair and a backslash can be used to quote them.
 454+
 455If the alias expansion is prefixed with an exclamation point,
 456it will be treated as a shell command.  For example, defining
 457"alias.new = !gitk --all --not ORIG_HEAD", the invocation
 458"git new" is equivalent to running the shell command
 459"gitk --all --not ORIG_HEAD".
 460
 461apply.whitespace::
 462        Tells 'git-apply' how to handle whitespaces, in the same way
 463        as the '--whitespace' option. See linkgit:git-apply[1].
 464
 465branch.autosetupmerge::
 466        Tells 'git-branch' and 'git-checkout' to setup new branches
 467        so that linkgit:git-pull[1] will appropriately merge from the
 468        starting point branch. Note that even if this option is not set,
 469        this behavior can be chosen per-branch using the `--track`
 470        and `--no-track` options. The valid settings are: `false` -- no
 471        automatic setup is done; `true` -- automatic setup is done when the
 472        starting point is a remote branch; `always` -- automatic setup is
 473        done when the starting point is either a local branch or remote
 474        branch. This option defaults to true.
 475
 476branch.autosetuprebase::
 477        When a new branch is created with 'git-branch' or 'git-checkout'
 478        that tracks another branch, this variable tells git to set
 479        up pull to rebase instead of merge (see "branch.<name>.rebase").
 480        When `never`, rebase is never automatically set to true.
 481        When `local`, rebase is set to true for tracked branches of
 482        other local branches.
 483        When `remote`, rebase is set to true for tracked branches of
 484        remote branches.
 485        When `always`, rebase will be set to true for all tracking
 486        branches.
 487        See "branch.autosetupmerge" for details on how to set up a
 488        branch to track another branch.
 489        This option defaults to never.
 490
 491branch.<name>.remote::
 492        When in branch <name>, it tells 'git-fetch' and 'git-push' which
 493        remote to fetch from/push to.  It defaults to `origin` if no remote is
 494        configured. `origin` is also used if you are not on any branch.
 495
 496branch.<name>.merge::
 497        Defines, together with branch.<name>.remote, the upstream branch
 498        for the given branch. It tells 'git-fetch'/'git-pull' which
 499        branch to merge and can also affect 'git-push' (see push.default).
 500        When in branch <name>, it tells 'git-fetch' the default
 501        refspec to be marked for merging in FETCH_HEAD. The value is
 502        handled like the remote part of a refspec, and must match a
 503        ref which is fetched from the remote given by
 504        "branch.<name>.remote".
 505        The merge information is used by 'git-pull' (which at first calls
 506        'git-fetch') to lookup the default branch for merging. Without
 507        this option, 'git-pull' defaults to merge the first refspec fetched.
 508        Specify multiple values to get an octopus merge.
 509        If you wish to setup 'git-pull' so that it merges into <name> from
 510        another branch in the local repository, you can point
 511        branch.<name>.merge to the desired branch, and use the special setting
 512        `.` (a period) for branch.<name>.remote.
 513
 514branch.<name>.mergeoptions::
 515        Sets default options for merging into branch <name>. The syntax and
 516        supported options are equal to that of linkgit:git-merge[1], but
 517        option values containing whitespace characters are currently not
 518        supported.
 519
 520branch.<name>.rebase::
 521        When true, rebase the branch <name> on top of the fetched branch,
 522        instead of merging the default branch from the default remote when
 523        "git pull" is run.
 524        *NOTE*: this is a possibly dangerous operation; do *not* use
 525        it unless you understand the implications (see linkgit:git-rebase[1]
 526        for details).
 527
 528browser.<tool>.cmd::
 529        Specify the command to invoke the specified browser. The
 530        specified command is evaluated in shell with the URLs passed
 531        as arguments. (See linkgit:git-web--browse[1].)
 532
 533browser.<tool>.path::
 534        Override the path for the given tool that may be used to
 535        browse HTML help (see '-w' option in linkgit:git-help[1]) or a
 536        working repository in gitweb (see linkgit:git-instaweb[1]).
 537
 538clean.requireForce::
 539        A boolean to make git-clean do nothing unless given -f
 540        or -n.   Defaults to true.
 541
 542color.branch::
 543        A boolean to enable/disable color in the output of
 544        linkgit:git-branch[1]. May be set to `always`,
 545        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 546        only when the output is to a terminal. Defaults to false.
 547
 548color.branch.<slot>::
 549        Use customized color for branch coloration. `<slot>` is one of
 550        `current` (the current branch), `local` (a local branch),
 551        `remote` (a tracking branch in refs/remotes/), `plain` (other
 552        refs).
 553+
 554The value for these configuration variables is a list of colors (at most
 555two) and attributes (at most one), separated by spaces.  The colors
 556accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`,
 557`magenta`, `cyan` and `white`; the attributes are `bold`, `dim`, `ul`,
 558`blink` and `reverse`.  The first color given is the foreground; the
 559second is the background.  The position of the attribute, if any,
 560doesn't matter.
 561
 562color.diff::
 563        When set to `always`, always use colors in patch.
 564        When false (or `never`), never.  When set to `true` or `auto`, use
 565        colors only when the output is to the terminal. Defaults to false.
 566
 567color.diff.<slot>::
 568        Use customized color for diff colorization.  `<slot>` specifies
 569        which part of the patch to use the specified color, and is one
 570        of `plain` (context text), `meta` (metainformation), `frag`
 571        (hunk header), `old` (removed lines), `new` (added lines),
 572        `commit` (commit headers), or `whitespace` (highlighting
 573        whitespace errors). The values of these variables may be specified as
 574        in color.branch.<slot>.
 575
 576color.grep::
 577        When set to `always`, always highlight matches.  When `false` (or
 578        `never`), never.  When set to `true` or `auto`, use color only
 579        when the output is written to the terminal.  Defaults to `false`.
 580
 581color.grep.external::
 582        The string value of this variable is passed to an external 'grep'
 583        command as a command line option if match highlighting is turned
 584        on.  If set to an empty string, no option is passed at all,
 585        turning off coloring for external 'grep' calls; this is the default.
 586        For GNU grep, set it to `--color=always` to highlight matches even
 587        when a pager is used.
 588
 589color.grep.match::
 590        Use customized color for matches.  The value of this variable
 591        may be specified as in color.branch.<slot>.  It is passed using
 592        the environment variables 'GREP_COLOR' and 'GREP_COLORS' when
 593        calling an external 'grep'.
 594
 595color.interactive::
 596        When set to `always`, always use colors for interactive prompts
 597        and displays (such as those used by "git-add --interactive").
 598        When false (or `never`), never.  When set to `true` or `auto`, use
 599        colors only when the output is to the terminal. Defaults to false.
 600
 601color.interactive.<slot>::
 602        Use customized color for 'git-add --interactive'
 603        output. `<slot>` may be `prompt`, `header`, `help` or `error`, for
 604        four distinct types of normal output from interactive
 605        programs.  The values of these variables may be specified as
 606        in color.branch.<slot>.
 607
 608color.pager::
 609        A boolean to enable/disable colored output when the pager is in
 610        use (default is true).
 611
 612color.showbranch::
 613        A boolean to enable/disable color in the output of
 614        linkgit:git-show-branch[1]. May be set to `always`,
 615        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 616        only when the output is to a terminal. Defaults to false.
 617
 618color.status::
 619        A boolean to enable/disable color in the output of
 620        linkgit:git-status[1]. May be set to `always`,
 621        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 622        only when the output is to a terminal. Defaults to false.
 623
 624color.status.<slot>::
 625        Use customized color for status colorization. `<slot>` is
 626        one of `header` (the header text of the status message),
 627        `added` or `updated` (files which are added but not committed),
 628        `changed` (files which are changed but not added in the index),
 629        `untracked` (files which are not tracked by git), or
 630        `nobranch` (the color the 'no branch' warning is shown in, defaulting
 631        to red). The values of these variables may be specified as in
 632        color.branch.<slot>.
 633
 634color.ui::
 635        When set to `always`, always use colors in all git commands which
 636        are capable of colored output. When false (or `never`), never. When
 637        set to `true` or `auto`, use colors only when the output is to the
 638        terminal. When more specific variables of color.* are set, they always
 639        take precedence over this setting. Defaults to false.
 640
 641commit.template::
 642        Specify a file to use as the template for new commit messages.
 643
 644diff.autorefreshindex::
 645        When using 'git-diff' to compare with work tree
 646        files, do not consider stat-only change as changed.
 647        Instead, silently run `git update-index --refresh` to
 648        update the cached stat information for paths whose
 649        contents in the work tree match the contents in the
 650        index.  This option defaults to true.  Note that this
 651        affects only 'git-diff' Porcelain, and not lower level
 652        'diff' commands, such as 'git-diff-files'.
 653
 654diff.external::
 655        If this config variable is set, diff generation is not
 656        performed using the internal diff machinery, but using the
 657        given command.  Can be overridden with the `GIT_EXTERNAL_DIFF'
 658        environment variable.  The command is called with parameters
 659        as described under "git Diffs" in linkgit:git[1].  Note: if
 660        you want to use an external diff program only on a subset of
 661        your files, you might want to use linkgit:gitattributes[5] instead.
 662
 663diff.mnemonicprefix::
 664        If set, 'git-diff' uses a prefix pair that is different from the
 665        standard "a/" and "b/" depending on what is being compared.  When
 666        this configuration is in effect, reverse diff output also swaps
 667        the order of the prefixes:
 668'git-diff';;
 669        compares the (i)ndex and the (w)ork tree;
 670'git-diff HEAD';;
 671         compares a (c)ommit and the (w)ork tree;
 672'git diff --cached';;
 673        compares a (c)ommit and the (i)ndex;
 674'git-diff HEAD:file1 file2';;
 675        compares an (o)bject and a (w)ork tree entity;
 676'git diff --no-index a b';;
 677        compares two non-git things (1) and (2).
 678
 679diff.renameLimit::
 680        The number of files to consider when performing the copy/rename
 681        detection; equivalent to the 'git-diff' option '-l'.
 682
 683diff.renames::
 684        Tells git to detect renames.  If set to any boolean value, it
 685        will enable basic rename detection.  If set to "copies" or
 686        "copy", it will detect copies, as well.
 687
 688diff.suppressBlankEmpty::
 689        A boolean to inhibit the standard behavior of printing a space
 690        before each empty output line. Defaults to false.
 691
 692diff.tool::
 693        Controls which diff tool is used.  `diff.tool` overrides
 694        `merge.tool` when used by linkgit:git-difftool[1] and has
 695        the same valid values as `merge.tool` minus "tortoisemerge"
 696        and plus "kompare".
 697
 698difftool.<tool>.path::
 699        Override the path for the given tool.  This is useful in case
 700        your tool is not in the PATH.
 701
 702difftool.<tool>.cmd::
 703        Specify the command to invoke the specified diff tool.
 704        The specified command is evaluated in shell with the following
 705        variables available:  'LOCAL' is set to the name of the temporary
 706        file containing the contents of the diff pre-image and 'REMOTE'
 707        is set to the name of the temporary file containing the contents
 708        of the diff post-image.
 709
 710difftool.prompt::
 711        Prompt before each invocation of the diff tool.
 712
 713diff.wordRegex::
 714        A POSIX Extended Regular Expression used to determine what is a "word"
 715        when performing word-by-word difference calculations.  Character
 716        sequences that match the regular expression are "words", all other
 717        characters are *ignorable* whitespace.
 718
 719fetch.unpackLimit::
 720        If the number of objects fetched over the git native
 721        transfer is below this
 722        limit, then the objects will be unpacked into loose object
 723        files. However if the number of received objects equals or
 724        exceeds this limit then the received pack will be stored as
 725        a pack, after adding any missing delta bases.  Storing the
 726        pack from a push can make the push operation complete faster,
 727        especially on slow filesystems.  If not set, the value of
 728        `transfer.unpackLimit` is used instead.
 729
 730format.attach::
 731        Enable multipart/mixed attachments as the default for
 732        'format-patch'.  The value can also be a double quoted string
 733        which will enable attachments as the default and set the
 734        value as the boundary.  See the --attach option in
 735        linkgit:git-format-patch[1].
 736
 737format.numbered::
 738        A boolean which can enable or disable sequence numbers in patch
 739        subjects.  It defaults to "auto" which enables it only if there
 740        is more than one patch.  It can be enabled or disabled for all
 741        messages by setting it to "true" or "false".  See --numbered
 742        option in linkgit:git-format-patch[1].
 743
 744format.headers::
 745        Additional email headers to include in a patch to be submitted
 746        by mail.  See linkgit:git-format-patch[1].
 747
 748format.cc::
 749        Additional "Cc:" headers to include in a patch to be submitted
 750        by mail.  See the --cc option in linkgit:git-format-patch[1].
 751
 752format.subjectprefix::
 753        The default for format-patch is to output files with the '[PATCH]'
 754        subject prefix. Use this variable to change that prefix.
 755
 756format.suffix::
 757        The default for format-patch is to output files with the suffix
 758        `.patch`. Use this variable to change that suffix (make sure to
 759        include the dot if you want it).
 760
 761format.pretty::
 762        The default pretty format for log/show/whatchanged command,
 763        See linkgit:git-log[1], linkgit:git-show[1],
 764        linkgit:git-whatchanged[1].
 765
 766format.thread::
 767        The default threading style for 'git-format-patch'.  Can be
 768        either a boolean value, `shallow` or `deep`.  `shallow`
 769        threading makes every mail a reply to the head of the series,
 770        where the head is chosen from the cover letter, the
 771        `\--in-reply-to`, and the first patch mail, in this order.
 772        `deep` threading makes every mail a reply to the previous one.
 773        A true boolean value is the same as `shallow`, and a false
 774        value disables threading.
 775
 776format.signoff::
 777    A boolean value which lets you enable the `-s/--signoff` option of
 778    format-patch by default. *Note:* Adding the Signed-off-by: line to a
 779    patch should be a conscious act and means that you certify you have
 780    the rights to submit this work under the same open source license.
 781    Please see the 'SubmittingPatches' document for further discussion.
 782
 783gc.aggressiveWindow::
 784        The window size parameter used in the delta compression
 785        algorithm used by 'git-gc --aggressive'.  This defaults
 786        to 10.
 787
 788gc.auto::
 789        When there are approximately more than this many loose
 790        objects in the repository, `git gc --auto` will pack them.
 791        Some Porcelain commands use this command to perform a
 792        light-weight garbage collection from time to time.  The
 793        default value is 6700.  Setting this to 0 disables it.
 794
 795gc.autopacklimit::
 796        When there are more than this many packs that are not
 797        marked with `*.keep` file in the repository, `git gc
 798        --auto` consolidates them into one larger pack.  The
 799        default value is 50.  Setting this to 0 disables it.
 800
 801gc.packrefs::
 802        'git-gc' does not run `git pack-refs` in a bare repository by
 803        default so that older dumb-transport clients can still fetch
 804        from the repository.  Setting this to `true` lets 'git-gc'
 805        to run `git pack-refs`.  Setting this to `false` tells
 806        'git-gc' never to run `git pack-refs`. The default setting is
 807        `notbare`. Enable it only when you know you do not have to
 808        support such clients.  The default setting will change to `true`
 809        at some stage, and setting this to `false` will continue to
 810        prevent `git pack-refs` from being run from 'git-gc'.
 811
 812gc.pruneexpire::
 813        When 'git-gc' is run, it will call 'prune --expire 2.weeks.ago'.
 814        Override the grace period with this config variable.  The value
 815        "now" may be used to disable this  grace period and always prune
 816        unreachable objects immediately.
 817
 818gc.reflogexpire::
 819        'git-reflog expire' removes reflog entries older than
 820        this time; defaults to 90 days.
 821
 822gc.reflogexpireunreachable::
 823        'git-reflog expire' removes reflog entries older than
 824        this time and are not reachable from the current tip;
 825        defaults to 30 days.
 826
 827gc.rerereresolved::
 828        Records of conflicted merge you resolved earlier are
 829        kept for this many days when 'git-rerere gc' is run.
 830        The default is 60 days.  See linkgit:git-rerere[1].
 831
 832gc.rerereunresolved::
 833        Records of conflicted merge you have not resolved are
 834        kept for this many days when 'git-rerere gc' is run.
 835        The default is 15 days.  See linkgit:git-rerere[1].
 836
 837gitcvs.commitmsgannotation::
 838        Append this string to each commit message. Set to empty string
 839        to disable this feature. Defaults to "via git-CVS emulator".
 840
 841gitcvs.enabled::
 842        Whether the CVS server interface is enabled for this repository.
 843        See linkgit:git-cvsserver[1].
 844
 845gitcvs.logfile::
 846        Path to a log file where the CVS server interface well... logs
 847        various stuff. See linkgit:git-cvsserver[1].
 848
 849gitcvs.usecrlfattr::
 850        If true, the server will look up the `crlf` attribute for
 851        files to determine the '-k' modes to use. If `crlf` is set,
 852        the '-k' mode will be left blank, so cvs clients will
 853        treat it as text. If `crlf` is explicitly unset, the file
 854        will be set with '-kb' mode, which suppresses any newline munging
 855        the client might otherwise do. If `crlf` is not specified,
 856        then 'gitcvs.allbinary' is used. See linkgit:gitattributes[5].
 857
 858gitcvs.allbinary::
 859        This is used if 'gitcvs.usecrlfattr' does not resolve
 860        the correct '-kb' mode to use. If true, all
 861        unresolved files are sent to the client in
 862        mode '-kb'. This causes the client to treat them
 863        as binary files, which suppresses any newline munging it
 864        otherwise might do. Alternatively, if it is set to "guess",
 865        then the contents of the file are examined to decide if
 866        it is binary, similar to 'core.autocrlf'.
 867
 868gitcvs.dbname::
 869        Database used by git-cvsserver to cache revision information
 870        derived from the git repository. The exact meaning depends on the
 871        used database driver, for SQLite (which is the default driver) this
 872        is a filename. Supports variable substitution (see
 873        linkgit:git-cvsserver[1] for details). May not contain semicolons (`;`).
 874        Default: '%Ggitcvs.%m.sqlite'
 875
 876gitcvs.dbdriver::
 877        Used Perl DBI driver. You can specify any available driver
 878        for this here, but it might not work. git-cvsserver is tested
 879        with 'DBD::SQLite', reported to work with 'DBD::Pg', and
 880        reported *not* to work with 'DBD::mysql'. Experimental feature.
 881        May not contain double colons (`:`). Default: 'SQLite'.
 882        See linkgit:git-cvsserver[1].
 883
 884gitcvs.dbuser, gitcvs.dbpass::
 885        Database user and password. Only useful if setting 'gitcvs.dbdriver',
 886        since SQLite has no concept of database users and/or passwords.
 887        'gitcvs.dbuser' supports variable substitution (see
 888        linkgit:git-cvsserver[1] for details).
 889
 890gitcvs.dbTableNamePrefix::
 891        Database table name prefix.  Prepended to the names of any
 892        database tables used, allowing a single database to be used
 893        for several repositories.  Supports variable substitution (see
 894        linkgit:git-cvsserver[1] for details).  Any non-alphabetic
 895        characters will be replaced with underscores.
 896
 897All gitcvs variables except for 'gitcvs.usecrlfattr' and
 898'gitcvs.allbinary' can also be specified as
 899'gitcvs.<access_method>.<varname>' (where 'access_method'
 900is one of "ext" and "pserver") to make them apply only for the given
 901access method.
 902
 903gui.commitmsgwidth::
 904        Defines how wide the commit message window is in the
 905        linkgit:git-gui[1]. "75" is the default.
 906
 907gui.diffcontext::
 908        Specifies how many context lines should be used in calls to diff
 909        made by the linkgit:git-gui[1]. The default is "5".
 910
 911gui.encoding::
 912        Specifies the default encoding to use for displaying of
 913        file contents in linkgit:git-gui[1] and linkgit:gitk[1].
 914        It can be overridden by setting the 'encoding' attribute
 915        for relevant files (see linkgit:gitattributes[5]).
 916        If this option is not set, the tools default to the
 917        locale encoding.
 918
 919gui.matchtrackingbranch::
 920        Determines if new branches created with linkgit:git-gui[1] should
 921        default to tracking remote branches with matching names or
 922        not. Default: "false".
 923
 924gui.newbranchtemplate::
 925        Is used as suggested name when creating new branches using the
 926        linkgit:git-gui[1].
 927
 928gui.pruneduringfetch::
 929        "true" if linkgit:git-gui[1] should prune tracking branches when
 930        performing a fetch. The default value is "false".
 931
 932gui.trustmtime::
 933        Determines if linkgit:git-gui[1] should trust the file modification
 934        timestamp or not. By default the timestamps are not trusted.
 935
 936gui.spellingdictionary::
 937        Specifies the dictionary used for spell checking commit messages in
 938        the linkgit:git-gui[1]. When set to "none" spell checking is turned
 939        off.
 940
 941gui.fastcopyblame::
 942        If true, 'git gui blame' uses '-C' instead of '-C -C' for original
 943        location detection. It makes blame significantly faster on huge
 944        repositories at the expense of less thorough copy detection.
 945
 946gui.copyblamethreshold::
 947        Specifies the threshold to use in 'git gui blame' original location
 948        detection, measured in alphanumeric characters. See the
 949        linkgit:git-blame[1] manual for more information on copy detection.
 950
 951gui.blamehistoryctx::
 952        Specifies the radius of history context in days to show in
 953        linkgit:gitk[1] for the selected commit, when the `Show History
 954        Context` menu item is invoked from 'git gui blame'. If this
 955        variable is set to zero, the whole history is shown.
 956
 957guitool.<name>.cmd::
 958        Specifies the shell command line to execute when the corresponding item
 959        of the linkgit:git-gui[1] `Tools` menu is invoked. This option is
 960        mandatory for every tool. The command is executed from the root of
 961        the working directory, and in the environment it receives the name of
 962        the tool as 'GIT_GUITOOL', the name of the currently selected file as
 963        'FILENAME', and the name of the current branch as 'CUR_BRANCH' (if
 964        the head is detached, 'CUR_BRANCH' is empty).
 965
 966guitool.<name>.needsfile::
 967        Run the tool only if a diff is selected in the GUI. It guarantees
 968        that 'FILENAME' is not empty.
 969
 970guitool.<name>.noconsole::
 971        Run the command silently, without creating a window to display its
 972        output.
 973
 974guitool.<name>.norescan::
 975        Don't rescan the working directory for changes after the tool
 976        finishes execution.
 977
 978guitool.<name>.confirm::
 979        Show a confirmation dialog before actually running the tool.
 980
 981guitool.<name>.argprompt::
 982        Request a string argument from the user, and pass it to the tool
 983        through the 'ARGS' environment variable. Since requesting an
 984        argument implies confirmation, the 'confirm' option has no effect
 985        if this is enabled. If the option is set to 'true', 'yes', or '1',
 986        the dialog uses a built-in generic prompt; otherwise the exact
 987        value of the variable is used.
 988
 989guitool.<name>.revprompt::
 990        Request a single valid revision from the user, and set the
 991        'REVISION' environment variable. In other aspects this option
 992        is similar to 'argprompt', and can be used together with it.
 993
 994guitool.<name>.revunmerged::
 995        Show only unmerged branches in the 'revprompt' subdialog.
 996        This is useful for tools similar to merge or rebase, but not
 997        for things like checkout or reset.
 998
 999guitool.<name>.title::
1000        Specifies the title to use for the prompt dialog. The default
1001        is the tool name.
1002
1003guitool.<name>.prompt::
1004        Specifies the general prompt string to display at the top of
1005        the dialog, before subsections for 'argprompt' and 'revprompt'.
1006        The default value includes the actual command.
1007
1008help.browser::
1009        Specify the browser that will be used to display help in the
1010        'web' format. See linkgit:git-help[1].
1011
1012help.format::
1013        Override the default help format used by linkgit:git-help[1].
1014        Values 'man', 'info', 'web' and 'html' are supported. 'man' is
1015        the default. 'web' and 'html' are the same.
1016
1017help.autocorrect::
1018        Automatically correct and execute mistyped commands after
1019        waiting for the given number of deciseconds (0.1 sec). If more
1020        than one command can be deduced from the entered text, nothing
1021        will be executed.  If the value of this option is negative,
1022        the corrected command will be executed immediately. If the
1023        value is 0 - the command will be just shown but not executed.
1024        This is the default.
1025
1026http.proxy::
1027        Override the HTTP proxy, normally configured using the 'http_proxy'
1028        environment variable (see linkgit:curl[1]).  This can be overridden
1029        on a per-remote basis; see remote.<name>.proxy
1030
1031http.sslVerify::
1032        Whether to verify the SSL certificate when fetching or pushing
1033        over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
1034        variable.
1035
1036http.sslCert::
1037        File containing the SSL certificate when fetching or pushing
1038        over HTTPS. Can be overridden by the 'GIT_SSL_CERT' environment
1039        variable.
1040
1041http.sslKey::
1042        File containing the SSL private key when fetching or pushing
1043        over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment
1044        variable.
1045
1046http.sslCAInfo::
1047        File containing the certificates to verify the peer with when
1048        fetching or pushing over HTTPS. Can be overridden by the
1049        'GIT_SSL_CAINFO' environment variable.
1050
1051http.sslCAPath::
1052        Path containing files with the CA certificates to verify the peer
1053        with when fetching or pushing over HTTPS. Can be overridden
1054        by the 'GIT_SSL_CAPATH' environment variable.
1055
1056http.maxRequests::
1057        How many HTTP requests to launch in parallel. Can be overridden
1058        by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5.
1059
1060http.lowSpeedLimit, http.lowSpeedTime::
1061        If the HTTP transfer speed is less than 'http.lowSpeedLimit'
1062        for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
1063        Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and
1064        'GIT_HTTP_LOW_SPEED_TIME' environment variables.
1065
1066http.noEPSV::
1067        A boolean which disables using of EPSV ftp command by curl.
1068        This can helpful with some "poor" ftp servers which don't
1069        support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
1070        environment variable. Default is false (curl will use EPSV).
1071
1072i18n.commitEncoding::
1073        Character encoding the commit messages are stored in; git itself
1074        does not care per se, but this information is necessary e.g. when
1075        importing commits from emails or in the gitk graphical history
1076        browser (and possibly at other places in the future or in other
1077        porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.
1078
1079i18n.logOutputEncoding::
1080        Character encoding the commit messages are converted to when
1081        running 'git-log' and friends.
1082
1083imap::
1084        The configuration variables in the 'imap' section are described
1085        in linkgit:git-imap-send[1].
1086
1087instaweb.browser::
1088        Specify the program that will be used to browse your working
1089        repository in gitweb. See linkgit:git-instaweb[1].
1090
1091instaweb.httpd::
1092        The HTTP daemon command-line to start gitweb on your working
1093        repository. See linkgit:git-instaweb[1].
1094
1095instaweb.local::
1096        If true the web server started by linkgit:git-instaweb[1] will
1097        be bound to the local IP (127.0.0.1).
1098
1099instaweb.modulepath::
1100        The module path for an apache httpd used by linkgit:git-instaweb[1].
1101
1102instaweb.port::
1103        The port number to bind the gitweb httpd to. See
1104        linkgit:git-instaweb[1].
1105
1106interactive.singlekey::
1107        In interactive programs, allow the user to provide one-letter
1108        input with a single key (i.e., without hitting enter).
1109        Currently this is used only by the `\--patch` mode of
1110        linkgit:git-add[1].  Note that this setting is silently
1111        ignored if portable keystroke input is not available.
1112
1113log.date::
1114        Set default date-time mode for the log command. Setting log.date
1115        value is similar to using 'git-log'\'s --date option. The value is one of the
1116        following alternatives: {relative,local,default,iso,rfc,short}.
1117        See linkgit:git-log[1].
1118
1119log.showroot::
1120        If true, the initial commit will be shown as a big creation event.
1121        This is equivalent to a diff against an empty tree.
1122        Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
1123        normally hide the root commit will now show it. True by default.
1124
1125mailmap.file::
1126        The location of an augmenting mailmap file. The default
1127        mailmap, located in the root of the repository, is loaded
1128        first, then the mailmap file pointed to by this variable.
1129        The location of the mailmap file may be in a repository
1130        subdirectory, or somewhere outside of the repository itself.
1131        See linkgit:git-shortlog[1] and linkgit:git-blame[1].
1132
1133man.viewer::
1134        Specify the programs that may be used to display help in the
1135        'man' format. See linkgit:git-help[1].
1136
1137man.<tool>.cmd::
1138        Specify the command to invoke the specified man viewer. The
1139        specified command is evaluated in shell with the man page
1140        passed as argument. (See linkgit:git-help[1].)
1141
1142man.<tool>.path::
1143        Override the path for the given tool that may be used to
1144        display help in the 'man' format. See linkgit:git-help[1].
1145
1146include::merge-config.txt[]
1147
1148mergetool.<tool>.path::
1149        Override the path for the given tool.  This is useful in case
1150        your tool is not in the PATH.
1151
1152mergetool.<tool>.cmd::
1153        Specify the command to invoke the specified merge tool.  The
1154        specified command is evaluated in shell with the following
1155        variables available: 'BASE' is the name of a temporary file
1156        containing the common base of the files to be merged, if available;
1157        'LOCAL' is the name of a temporary file containing the contents of
1158        the file on the current branch; 'REMOTE' is the name of a temporary
1159        file containing the contents of the file from the branch being
1160        merged; 'MERGED' contains the name of the file to which the merge
1161        tool should write the results of a successful merge.
1162
1163mergetool.<tool>.trustExitCode::
1164        For a custom merge command, specify whether the exit code of
1165        the merge command can be used to determine whether the merge was
1166        successful.  If this is not set to true then the merge target file
1167        timestamp is checked and the merge assumed to have been successful
1168        if the file has been updated, otherwise the user is prompted to
1169        indicate the success of the merge.
1170
1171mergetool.keepBackup::
1172        After performing a merge, the original file with conflict markers
1173        can be saved as a file with a `.orig` extension.  If this variable
1174        is set to `false` then this file is not preserved.  Defaults to
1175        `true` (i.e. keep the backup files).
1176
1177mergetool.keepTemporaries::
1178        When invoking a custom merge tool, git uses a set of temporary
1179        files to pass to the tool. If the tool returns an error and this
1180        variable is set to `true`, then these temporary files will be
1181        preserved, otherwise they will be removed after the tool has
1182        exited. Defaults to `false`.
1183
1184mergetool.prompt::
1185        Prompt before each invocation of the merge resolution program.
1186
1187pack.window::
1188        The size of the window used by linkgit:git-pack-objects[1] when no
1189        window size is given on the command line. Defaults to 10.
1190
1191pack.depth::
1192        The maximum delta depth used by linkgit:git-pack-objects[1] when no
1193        maximum depth is given on the command line. Defaults to 50.
1194
1195pack.windowMemory::
1196        The window memory size limit used by linkgit:git-pack-objects[1]
1197        when no limit is given on the command line.  The value can be
1198        suffixed with "k", "m", or "g".  Defaults to 0, meaning no
1199        limit.
1200
1201pack.compression::
1202        An integer -1..9, indicating the compression level for objects
1203        in a pack file. -1 is the zlib default. 0 means no
1204        compression, and 1..9 are various speed/size tradeoffs, 9 being
1205        slowest.  If not set,  defaults to core.compression.  If that is
1206        not set,  defaults to -1, the zlib default, which is "a default
1207        compromise between speed and compression (currently equivalent
1208        to level 6)."
1209
1210pack.deltaCacheSize::
1211        The maximum memory in bytes used for caching deltas in
1212        linkgit:git-pack-objects[1].
1213        A value of 0 means no limit. Defaults to 0.
1214
1215pack.deltaCacheLimit::
1216        The maximum size of a delta, that is cached in
1217        linkgit:git-pack-objects[1]. Defaults to 1000.
1218
1219pack.threads::
1220        Specifies the number of threads to spawn when searching for best
1221        delta matches.  This requires that linkgit:git-pack-objects[1]
1222        be compiled with pthreads otherwise this option is ignored with a
1223        warning. This is meant to reduce packing time on multiprocessor
1224        machines. The required amount of memory for the delta search window
1225        is however multiplied by the number of threads.
1226        Specifying 0 will cause git to auto-detect the number of CPU's
1227        and set the number of threads accordingly.
1228
1229pack.indexVersion::
1230        Specify the default pack index version.  Valid values are 1 for
1231        legacy pack index used by Git versions prior to 1.5.2, and 2 for
1232        the new pack index with capabilities for packs larger than 4 GB
1233        as well as proper protection against the repacking of corrupted
1234        packs.  Version 2 is the default.  Note that version 2 is enforced
1235        and this config option ignored whenever the corresponding pack is
1236        larger than 2 GB.
1237+
1238If you have an old git that does not understand the version 2 `{asterisk}.idx` file,
1239cloning or fetching over a non native protocol (e.g. "http" and "rsync")
1240that will copy both `{asterisk}.pack` file and corresponding `{asterisk}.idx` file from the
1241other side may give you a repository that cannot be accessed with your
1242older version of git. If the `{asterisk}.pack` file is smaller than 2 GB, however,
1243you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
1244the `{asterisk}.idx` file.
1245
1246pack.packSizeLimit::
1247        The default maximum size of a pack.  This setting only affects
1248        packing to a file, i.e. the git:// protocol is unaffected.  It
1249        can be overridden by the `\--max-pack-size` option of
1250        linkgit:git-repack[1].
1251
1252pager.<cmd>::
1253        Allows turning on or off pagination of the output of a
1254        particular git subcommand when writing to a tty.  If
1255        `\--paginate` or `\--no-pager` is specified on the command line,
1256        it takes precedence over this option.  To disable pagination for
1257        all commands, set `core.pager` or `GIT_PAGER` to `cat`.
1258
1259pull.octopus::
1260        The default merge strategy to use when pulling multiple branches
1261        at once.
1262
1263pull.twohead::
1264        The default merge strategy to use when pulling a single branch.
1265
1266push.default::
1267        Defines the action git push should take if no refspec is given
1268        on the command line, no refspec is configured in the remote, and
1269        no refspec is implied by any of the options given on the command
1270        line. Possible values are:
1271+
1272* `nothing` do not push anything.
1273* `matching` push all matching branches.
1274  All branches having the same name in both ends are considered to be
1275  matching. This is the default.
1276* `tracking` push the current branch to its upstream branch.
1277* `current` push the current branch to a branch of the same name.
1278
1279rebase.stat::
1280        Whether to show a diffstat of what changed upstream since the last
1281        rebase. False by default.
1282
1283receive.fsckObjects::
1284        If it is set to true, git-receive-pack will check all received
1285        objects. It will abort in the case of a malformed object or a
1286        broken link. The result of an abort are only dangling objects.
1287        Defaults to false.
1288
1289receive.unpackLimit::
1290        If the number of objects received in a push is below this
1291        limit then the objects will be unpacked into loose object
1292        files. However if the number of received objects equals or
1293        exceeds this limit then the received pack will be stored as
1294        a pack, after adding any missing delta bases.  Storing the
1295        pack from a push can make the push operation complete faster,
1296        especially on slow filesystems.  If not set, the value of
1297        `transfer.unpackLimit` is used instead.
1298
1299receive.denyDeletes::
1300        If set to true, git-receive-pack will deny a ref update that deletes
1301        the ref. Use this to prevent such a ref deletion via a push.
1302
1303receive.denyCurrentBranch::
1304        If set to true or "refuse", receive-pack will deny a ref update
1305        to the currently checked out branch of a non-bare repository.
1306        Such a push is potentially dangerous because it brings the HEAD
1307        out of sync with the index and working tree. If set to "warn",
1308        print a warning of such a push to stderr, but allow the push to
1309        proceed. If set to false or "ignore", allow such pushes with no
1310        message. Defaults to "warn".
1311
1312receive.denyNonFastForwards::
1313        If set to true, git-receive-pack will deny a ref update which is
1314        not a fast forward. Use this to prevent such an update via a push,
1315        even if that push is forced. This configuration variable is
1316        set when initializing a shared repository.
1317
1318remote.<name>.url::
1319        The URL of a remote repository.  See linkgit:git-fetch[1] or
1320        linkgit:git-push[1].
1321
1322remote.<name>.pushurl::
1323        The push URL of a remote repository.  See linkgit:git-push[1].
1324
1325remote.<name>.proxy::
1326        For remotes that require curl (http, https and ftp), the URL to
1327        the proxy to use for that remote.  Set to the empty string to
1328        disable proxying for that remote.
1329
1330remote.<name>.fetch::
1331        The default set of "refspec" for linkgit:git-fetch[1]. See
1332        linkgit:git-fetch[1].
1333
1334remote.<name>.push::
1335        The default set of "refspec" for linkgit:git-push[1]. See
1336        linkgit:git-push[1].
1337
1338remote.<name>.mirror::
1339        If true, pushing to this remote will automatically behave
1340        as if the `\--mirror` option was given on the command line.
1341
1342remote.<name>.skipDefaultUpdate::
1343        If true, this remote will be skipped by default when updating
1344        using the update subcommand of linkgit:git-remote[1].
1345
1346remote.<name>.receivepack::
1347        The default program to execute on the remote side when pushing.  See
1348        option \--receive-pack of linkgit:git-push[1].
1349
1350remote.<name>.uploadpack::
1351        The default program to execute on the remote side when fetching.  See
1352        option \--upload-pack of linkgit:git-fetch-pack[1].
1353
1354remote.<name>.tagopt::
1355        Setting this value to \--no-tags disables automatic tag following when
1356        fetching from remote <name>
1357
1358remotes.<group>::
1359        The list of remotes which are fetched by "git remote update
1360        <group>".  See linkgit:git-remote[1].
1361
1362repack.usedeltabaseoffset::
1363        By default, linkgit:git-repack[1] creates packs that use
1364        delta-base offset. If you need to share your repository with
1365        git older than version 1.4.4, either directly or via a dumb
1366        protocol such as http, then you need to set this option to
1367        "false" and repack. Access from old git versions over the
1368        native protocol are unaffected by this option.
1369
1370rerere.autoupdate::
1371        When set to true, `git-rerere` updates the index with the
1372        resulting contents after it cleanly resolves conflicts using
1373        previously recorded resolution.  Defaults to false.
1374
1375rerere.enabled::
1376        Activate recording of resolved conflicts, so that identical
1377        conflict hunks can be resolved automatically, should they
1378        be encountered again.  linkgit:git-rerere[1] command is by
1379        default enabled if you create `rr-cache` directory under
1380        `$GIT_DIR`, but can be disabled by setting this option to false.
1381
1382showbranch.default::
1383        The default set of branches for linkgit:git-show-branch[1].
1384        See linkgit:git-show-branch[1].
1385
1386status.relativePaths::
1387        By default, linkgit:git-status[1] shows paths relative to the
1388        current directory. Setting this variable to `false` shows paths
1389        relative to the repository root (this was the default for git
1390        prior to v1.5.4).
1391
1392status.showUntrackedFiles::
1393        By default, linkgit:git-status[1] and linkgit:git-commit[1] show
1394        files which are not currently tracked by Git. Directories which
1395        contain only untracked files, are shown with the directory name
1396        only. Showing untracked files means that Git needs to lstat() all
1397        all the files in the whole repository, which might be slow on some
1398        systems. So, this variable controls how the commands displays
1399        the untracked files. Possible values are:
1400+
1401--
1402        - 'no'     - Show no untracked files
1403        - 'normal' - Shows untracked files and directories
1404        - 'all'    - Shows also individual files in untracked directories.
1405--
1406+
1407If this variable is not specified, it defaults to 'normal'.
1408This variable can be overridden with the -u|--untracked-files option
1409of linkgit:git-status[1] and linkgit:git-commit[1].
1410
1411tar.umask::
1412        This variable can be used to restrict the permission bits of
1413        tar archive entries.  The default is 0002, which turns off the
1414        world write bit.  The special value "user" indicates that the
1415        archiving user's umask will be used instead.  See umask(2) and
1416        linkgit:git-archive[1].
1417
1418transfer.unpackLimit::
1419        When `fetch.unpackLimit` or `receive.unpackLimit` are
1420        not set, the value of this variable is used instead.
1421        The default value is 100.
1422
1423url.<base>.insteadOf::
1424        Any URL that starts with this value will be rewritten to
1425        start, instead, with <base>. In cases where some site serves a
1426        large number of repositories, and serves them with multiple
1427        access methods, and some users need to use different access
1428        methods, this feature allows people to specify any of the
1429        equivalent URLs and have git automatically rewrite the URL to
1430        the best alternative for the particular user, even for a
1431        never-before-seen repository on the site.  When more than one
1432        insteadOf strings match a given URL, the longest match is used.
1433
1434user.email::
1435        Your email address to be recorded in any newly created commits.
1436        Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and
1437        'EMAIL' environment variables.  See linkgit:git-commit-tree[1].
1438
1439user.name::
1440        Your full name to be recorded in any newly created commits.
1441        Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
1442        environment variables.  See linkgit:git-commit-tree[1].
1443
1444user.signingkey::
1445        If linkgit:git-tag[1] is not selecting the key you want it to
1446        automatically when creating a signed tag, you can override the
1447        default selection with this variable.  This option is passed
1448        unchanged to gpg's --local-user parameter, so you may specify a key
1449        using any method that gpg supports.
1450
1451web.browser::
1452        Specify a web browser that may be used by some commands.
1453        Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
1454        may use it.
