   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 (and the remainder of the line after the section
  53header) are recognized as setting variables, in the form
  54'name = value'.  If there is no equal sign on the line, the entire line
  55is taken as 'name' and the variable is recognized as boolean "true".
  56The variable names are case-insensitive and only alphanumeric
  57characters and `-` are allowed.  There can be more than one value
  58for a given variable; we say then that variable is multivalued.
  59
  60Leading and trailing whitespace in a variable value is discarded.
  61Internal whitespace within a variable value is retained verbatim.
  62
  63The values following the equals sign in variable assign are all either
  64a string, an integer, or a boolean.  Boolean values may be given as yes/no,
  650/1, true/false or on/off.  Case is not significant in boolean values, when
  66converting value to the canonical form using '--bool' type specifier;
  67'git-config' will ensure that the output is "true" or "false".
  68
  69String values may be entirely or partially enclosed in double quotes.
  70You need to enclose variable values in double quotes if you want to
  71preserve leading or trailing whitespace, or if the variable value contains
  72comment characters (i.e. it contains '#' or ';').
  73Double quote `"` and backslash `\` characters in variable values must
  74be escaped: use `\"` for `"` and `\\` for `\`.
  75
  76The following escape sequences (beside `\"` and `\\`) are recognized:
  77`\n` for newline character (NL), `\t` for horizontal tabulation (HT, TAB)
  78and `\b` for backspace (BS).  No other char escape sequence, nor octal
  79char sequences are valid.
  80
  81Variable values ending in a `\` are continued on the next line in the
  82customary UNIX fashion.
  83
  84Some variables may require a special value format.

 122        pushNonFastForward::
 123                Advice shown when linkgit:git-push[1] refuses
 124                non-fast-forward refs. Default: true.
 125        statusHints::
 126                Directions on how to stage/unstage/add shown in the
 127                output of linkgit:git-status[1] and the template shown
 128                when writing commit messages. Default: true.
 129        commitBeforeMerge::
 130                Advice shown when linkgit:git-merge[1] refuses to
 131                merge to avoid overwritting local changes.
 132                Default: true.
 133--
 134
 135core.fileMode::
 136        If false, the executable bit differences between the index and
 137        the working copy are ignored; useful on broken filesystems like FAT.
 138        See linkgit:git-update-index[1].
 139+
 140The default is true, except linkgit:git-clone[1] or linkgit:git-init[1]
 141will probe and set core.fileMode false if appropriate when the
 142repository is created.
 143
 144core.ignoreCygwinFSTricks::
 145        This option is only used by Cygwin implementation of Git. If false,
 146        the Cygwin stat() and lstat() functions are used. This may be useful
 147        if your repository consists of a few separate directories joined in
 148        one hierarchy using Cygwin mount. If true, Git uses native Win32 API
 149        whenever it is possible and falls back to Cygwin functions only to
 150        handle symbol links. The native mode is more than twice faster than
 151        normal Cygwin l/stat() functions. True by default, unless core.filemode
 152        is true, in which case ignoreCygwinFSTricks is ignored as Cygwin's
 153        POSIX emulation is required to support core.filemode.
 154
 155core.ignorecase::
 156        If true, this option enables various workarounds to enable
 157        git to work better on filesystems that are not case sensitive,
 158        like FAT. For example, if a directory listing finds
 159        "makefile" when git expects "Makefile", git will assume
 160        it is really the same file, and continue to remember it as
 161        "Makefile".
 162+
 163The default is false, except linkgit:git-clone[1] or linkgit:git-init[1]
 164will probe and set core.ignorecase true if appropriate when the repository
 165is created.
 166
 167core.trustctime::
 168        If false, the ctime differences between the index and the
 169        working copy are ignored; useful when the inode change time
 170        is regularly modified by something outside Git (file system
 171        crawlers and some backup systems).
 172        See linkgit:git-update-index[1]. True by default.
 173
 174core.quotepath::
 175        The commands that output paths (e.g. 'ls-files',
 176        'diff'), when not given the `-z` option, will quote
 177        "unusual" characters in the pathname by enclosing the
 178        pathname in a double-quote pair and with backslashes the
 179        same way strings in C source code are quoted.  If this
 180        variable is set to false, the bytes higher than 0x80 are
 181        not quoted but output as verbatim.  Note that double
 182        quote, backslash and control characters are always
 183        quoted without `-z` regardless of the setting of this
 184        variable.
 185
 186core.autocrlf::
 187        If true, makes git convert `CRLF` at the end of lines in text files to
 188        `LF` when reading from the filesystem, and convert in reverse when
 189        writing to the filesystem.  The variable can be set to
 190        'input', in which case the conversion happens only while
 191        reading from the filesystem but files are written out with
 192        `LF` at the end of lines.  A file is considered
 193        "text" (i.e. be subjected to the autocrlf mechanism) based on
 194        the file's `crlf` attribute, or if `crlf` is unspecified,
 195        based on the file's contents.  See linkgit:gitattributes[5].
 196
 197core.safecrlf::
 198        If true, makes git check if converting `CRLF` as controlled by
 199        `core.autocrlf` is reversible.  Git will verify if a command
 200        modifies a file in the work tree either directly or indirectly.
 201        For example, committing a file followed by checking out the
 202        same file should yield the original file in the work tree.  If
 203        this is not the case for the current setting of
 204        `core.autocrlf`, git will reject the file.  The variable can
 205        be set to "warn", in which case git will only warn about an
 206        irreversible conversion but continue the operation.
 207+
 208CRLF conversion bears a slight chance of corrupting data.
 209autocrlf=true will convert CRLF to LF during commit and LF to
 210CRLF during checkout.  A file that contains a mixture of LF and
 211CRLF before the commit cannot be recreated by git.  For text
 212files this is the right thing to do: it corrects line endings
 213such that we have only LF line endings in the repository.
 214But for binary files that are accidentally classified as text the
 215conversion can corrupt data.
 216+
 217If you recognize such corruption early you can easily fix it by
 218setting the conversion type explicitly in .gitattributes.  Right
 219after committing you still have the original file in your work
 220tree and this file is not yet corrupted.  You can explicitly tell
 221git that this file is binary and git will handle the file
 222appropriately.
 223+
 224Unfortunately, the desired effect of cleaning up text files with
 225mixed line endings and the undesired effect of corrupting binary
 226files cannot be distinguished.  In both cases CRLFs are removed
 227in an irreversible way.  For text files this is the right thing
 228to do because CRLFs are line endings, while for binary files
 229converting CRLFs corrupts data.
 230+
 231Note, this safety check does not mean that a checkout will generate a
 232file identical to the original file for a different setting of
 233`core.autocrlf`, but only for the current one.  For example, a text
 234file with `LF` would be accepted with `core.autocrlf=input` and could
 235later be checked out with `core.autocrlf=true`, in which case the
 236resulting file would contain `CRLF`, although the original file
 237contained `LF`.  However, in both work trees the line endings would be
 238consistent, that is either all `LF` or all `CRLF`, but never mixed.  A
 239file with mixed line endings would be reported by the `core.safecrlf`
 240mechanism.
 241
 242core.symlinks::
 243        If false, symbolic links are checked out as small plain files that
 244        contain the link text. linkgit:git-update-index[1] and
 245        linkgit:git-add[1] will not change the recorded type to regular
 246        file. Useful on filesystems like FAT that do not support
 247        symbolic links.
 248+
 249The default is true, except linkgit:git-clone[1] or linkgit:git-init[1]
 250will probe and set core.symlinks false if appropriate when the repository
 251is created.
 252
 253core.gitProxy::
 254        A "proxy command" to execute (as 'command host port') instead
 255        of establishing direct connection to the remote server when
 256        using the git protocol for fetching. If the variable value is
 257        in the "COMMAND for DOMAIN" format, the command is applied only
 258        on hostnames ending with the specified domain string. This variable
 259        may be set multiple times and is matched in the given order;
 260        the first match wins.
 261+
 262Can be overridden by the 'GIT_PROXY_COMMAND' environment variable
 263(which always applies universally, without the special "for"
 264handling).
 265+
 266The special string `none` can be used as the proxy command to
 267specify that no proxy be used for a given domain pattern.
 268This is useful for excluding servers inside a firewall from
 269proxy use, while defaulting to a common proxy for external domains.
 270
 271core.ignoreStat::
 272        If true, commands which modify both the working tree and the index
 273        will mark the updated paths with the "assume unchanged" bit in the
 274        index. These marked files are then assumed to stay unchanged in the
 275        working copy, until you mark them otherwise manually - Git will not
 276        detect the file changes by lstat() calls. This is useful on systems
 277        where those are very slow, such as Microsoft Windows.
 278        See linkgit:git-update-index[1].
 279        False by default.
 280
 281core.preferSymlinkRefs::
 282        Instead of the default "symref" format for HEAD
 283        and other symbolic reference files, use symbolic links.
 284        This is sometimes needed to work with old scripts that
 285        expect HEAD to be a symbolic link.
 286
 287core.bare::
 288        If true this repository is assumed to be 'bare' and has no
 289        working directory associated with it.  If this is the case a
 290        number of commands that require a working directory will be
 291        disabled, such as linkgit:git-add[1] or linkgit:git-merge[1].
 292+
 293This setting is automatically guessed by linkgit:git-clone[1] or
 294linkgit:git-init[1] when the repository was created.  By default a
 295repository that ends in "/.git" is assumed to be not bare (bare =
 296false), while all other repositories are assumed to be bare (bare
 297= true).
 298
 299core.worktree::
 300        Set the path to the root of the work tree.
 301        This can be overridden by the GIT_WORK_TREE environment
 302        variable and the '--work-tree' command line option. It can be
 303        an absolute path or a relative path to the .git directory,
 304        either specified by --git-dir or GIT_DIR, or automatically
 305        discovered.
 306        If --git-dir or GIT_DIR are specified but none of
 307        --work-tree, GIT_WORK_TREE and core.worktree is specified,
 308        the current working directory is regarded as the root of the
 309        work tree.
 310+
 311Note that this variable is honored even when set in a configuration
 312file in a ".git" subdirectory of a directory, and its value differs
 313from the latter directory (e.g. "/path/to/.git/config" has
 314core.worktree set to "/different/path"), which is most likely a
 315misconfiguration.  Running git commands in "/path/to" directory will
 316still use "/different/path" as the root of the work tree and can cause
 317great confusion to the users.
 318
 319core.logAllRefUpdates::
 320        Enable the reflog. Updates to a ref <ref> is logged to the file
 321        "$GIT_DIR/logs/<ref>", by appending the new and old
 322        SHA1, the date/time and the reason of the update, but
 323        only when the file exists.  If this configuration
 324        variable is set to true, missing "$GIT_DIR/logs/<ref>"
 325        file is automatically created for branch heads.
 326+
 327This information can be used to determine what commit
 328was the tip of a branch "2 days ago".
 329+
 330This value is true by default in a repository that has
 331a working directory associated with it, and false by
 332default in a bare repository.
 333
 334core.repositoryFormatVersion::
 335        Internal variable identifying the repository format and layout
 336        version.
 337
 338core.sharedRepository::
 339        When 'group' (or 'true'), the repository is made shareable between
 340        several users in a group (making sure all the files and objects are
 341        group-writable). When 'all' (or 'world' or 'everybody'), the
 342        repository will be readable by all users, additionally to being
 343        group-shareable. When 'umask' (or 'false'), git will use permissions
 344        reported by umask(2). When '0xxx', where '0xxx' is an octal number,
 345        files in the repository will have this mode value. '0xxx' will override
 346        user's umask value (whereas the other options will only override
 347        requested parts of the user's umask value). Examples: '0660' will make
 348        the repo read/write-able for the owner and group, but inaccessible to
 349        others (equivalent to 'group' unless umask is e.g. '0022'). '0640' is a
 350        repository that is group-readable but not group-writable.
 351        See linkgit:git-init[1]. False by default.
 352
 353core.warnAmbiguousRefs::
 354        If true, git will warn you if the ref name you passed it is ambiguous
 355        and might match multiple refs in the .git/refs/ tree. True by default.
 356
 357core.compression::
 358        An integer -1..9, indicating a default compression level.
 359        -1 is the zlib default. 0 means no compression,
 360        and 1..9 are various speed/size tradeoffs, 9 being slowest.
 361        If set, this provides a default to other compression variables,
 362        such as 'core.loosecompression' and 'pack.compression'.
 363
 364core.loosecompression::
 365        An integer -1..9, indicating the compression level for objects that
 366        are not in a pack file. -1 is the zlib default. 0 means no
 367        compression, and 1..9 are various speed/size tradeoffs, 9 being
 368        slowest.  If not set,  defaults to core.compression.  If that is
 369        not set,  defaults to 1 (best speed).
 370
 371core.packedGitWindowSize::
 372        Number of bytes of a pack file to map into memory in a
 373        single mapping operation.  Larger window sizes may allow
 374        your system to process a smaller number of large pack files
 375        more quickly.  Smaller window sizes will negatively affect
 376        performance due to increased calls to the operating system's
 377        memory manager, but may improve performance when accessing
 378        a large number of large pack files.
 379+
 380Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
 381MiB on 32 bit platforms and 1 GiB on 64 bit platforms.  This should
 382be reasonable for all users/operating systems.  You probably do
 383not need to adjust this value.
 384+
 385Common unit suffixes of 'k', 'm', or 'g' are supported.
 386
 387core.packedGitLimit::
 388        Maximum number of bytes to map simultaneously into memory
 389        from pack files.  If Git needs to access more than this many
 390        bytes at once to complete an operation it will unmap existing
 391        regions to reclaim virtual address space within the process.
 392+
 393Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms.
 394This should be reasonable for all users/operating systems, except on
 395the largest projects.  You probably do not need to adjust this value.
 396+
 397Common unit suffixes of 'k', 'm', or 'g' are supported.
 398
 399core.deltaBaseCacheLimit::
 400        Maximum number of bytes to reserve for caching base objects
 401        that multiple deltafied objects reference.  By storing the
 402        entire decompressed base objects in a cache Git is able
 403        to avoid unpacking and decompressing frequently used base
 404        objects multiple times.
 405+
 406Default is 16 MiB on all platforms.  This should be reasonable
 407for all users/operating systems, except on the largest projects.
 408You probably do not need to adjust this value.
 409+
 410Common unit suffixes of 'k', 'm', or 'g' are supported.
 411
 412core.excludesfile::
 413        In addition to '.gitignore' (per-directory) and
 414        '.git/info/exclude', git looks into this file for patterns
 415        of files which are not meant to be tracked.  "{tilde}/" is expanded
 416        to the value of `$HOME` and "{tilde}user/" to the specified user's
 417        home directory.  See linkgit:gitignore[5].
 418
 419core.editor::
 420        Commands such as `commit` and `tag` that lets you edit
 421        messages by launching an editor uses the value of this
 422        variable when it is set, and the environment variable
 423        `GIT_EDITOR` is not set.  See linkgit:git-var[1].
 424
 425core.pager::
 426        The command that git will use to paginate output.  Can
 427        be overridden with the `GIT_PAGER` environment
 428        variable.  Note that git sets the `LESS` environment
 429        variable to `FRSX` if it is unset when it runs the
 430        pager.  One can change these settings by setting the
 431        `LESS` variable to some other value.  Alternately,
 432        these settings can be overridden on a project or
 433        global basis by setting the `core.pager` option.
 434        Setting `core.pager` has no affect on the `LESS`
 435        environment variable behaviour above, so if you want
 436        to override git's default settings this way, you need
 437        to be explicit.  For example, to disable the S option
 438        in a backward compatible manner, set `core.pager`
 439        to `less -+$LESS -FRX`.  This will be passed to the
 440        shell by git, which will translate the final command to
 441        `LESS=FRSX less -+FRSX -FRX`.
 442
 443core.whitespace::
 444        A comma separated list of common whitespace problems to
 445        notice.  'git-diff' will use `color.diff.whitespace` to
 446        highlight them, and 'git-apply --whitespace=error' will
 447        consider them as errors.  You can prefix `-` to disable
 448        any of them (e.g. `-trailing-space`):
 449+
 450* `blank-at-eol` treats trailing whitespaces at the end of the line
 451  as an error (enabled by default).
 452* `space-before-tab` treats a space character that appears immediately
 453  before a tab character in the initial indent part of the line as an
 454  error (enabled by default).
 455* `indent-with-non-tab` treats a line that is indented with 8 or more
 456  space characters as an error (not enabled by default).
 457* `blank-at-eof` treats blank lines added at the end of file as an error
 458  (enabled by default).
 459* `trailing-space` is a short-hand to cover both `blank-at-eol` and
 460  `blank-at-eof`.
 461* `cr-at-eol` treats a carriage-return at the end of line as
 462  part of the line terminator, i.e. with it, `trailing-space`
 463  does not trigger if the character before such a carriage-return
 464  is not a whitespace (not enabled by default).
 465
 466core.fsyncobjectfiles::
 467        This boolean will enable 'fsync()' when writing object files.
 468+
 469This is a total waste of time and effort on a filesystem that orders
 470data writes properly, but can be useful for filesystems that do not use
 471journalling (traditional UNIX filesystems) or that only journal metadata
 472and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback").
 473
 474core.preloadindex::
 475        Enable parallel index preload for operations like 'git diff'
 476+
 477This can speed up operations like 'git diff' and 'git status' especially
 478on filesystems like NFS that have weak caching semantics and thus
 479relatively high IO latencies.  With this set to 'true', git will do the
 480index comparison to the filesystem data in parallel, allowing
 481overlapping IO's.
 482
 483core.createObject::
 484        You can set this to 'link', in which case a hardlink followed by
 485        a delete of the source are used to make sure that object creation
 486        will not overwrite existing objects.
 487+
 488On some file system/operating system combinations, this is unreliable.
 489Set this config setting to 'rename' there; However, This will remove the
 490check that makes sure that existing object files will not get overwritten.
 491
 492core.notesRef::
 493        When showing commit messages, also show notes which are stored in
 494        the given ref.  This ref is expected to contain files named
 495        after the full SHA-1 of the commit they annotate.
 496+
 497If such a file exists in the given ref, the referenced blob is read, and
 498appended to the commit message, separated by a "Notes:" line.  If the
 499given ref itself does not exist, it is not an error, but means that no
 500notes should be printed.
 501+
 502This setting defaults to "refs/notes/commits", and can be overridden by
 503the `GIT_NOTES_REF` environment variable.
 504
 505add.ignore-errors::
 506        Tells 'git-add' to continue adding files when some files cannot be
 507        added due to indexing errors. Equivalent to the '--ignore-errors'
 508        option of linkgit:git-add[1].
 509
 510alias.*::
 511        Command aliases for the linkgit:git[1] command wrapper - e.g.
 512        after defining "alias.last = cat-file commit HEAD", the invocation
 513        "git last" is equivalent to "git cat-file commit HEAD". To avoid
 514        confusion and troubles with script usage, aliases that
 515        hide existing git commands are ignored. Arguments are split by
 516        spaces, the usual shell quoting and escaping is supported.
 517        quote pair and a backslash can be used to quote them.
 518+
 519If the alias expansion is prefixed with an exclamation point,
 520it will be treated as a shell command.  For example, defining
 521"alias.new = !gitk --all --not ORIG_HEAD", the invocation
 522"git new" is equivalent to running the shell command
 523"gitk --all --not ORIG_HEAD".  Note that shell commands will be
 524executed from the top-level directory of a repository, which may
 525not necessarily be the current directory.
 526
 527apply.ignorewhitespace::
 528        When set to 'change', tells 'git-apply' to ignore changes in
 529        whitespace, in the same way as the '--ignore-space-change'
 530        option.
 531        When set to one of: no, none, never, false tells 'git-apply' to
 532        respect all whitespace differences.
 533        See linkgit:git-apply[1].
 534
 535apply.whitespace::
 536        Tells 'git-apply' how to handle whitespaces, in the same way
 537        as the '--whitespace' option. See linkgit:git-apply[1].
 538
 539branch.autosetupmerge::
 540        Tells 'git-branch' and 'git-checkout' to setup new branches
 541        so that linkgit:git-pull[1] will appropriately merge from the
 542        starting point branch. Note that even if this option is not set,
 543        this behavior can be chosen per-branch using the `--track`
 544        and `--no-track` options. The valid settings are: `false` -- no
 545        automatic setup is done; `true` -- automatic setup is done when the
 546        starting point is a remote branch; `always` -- automatic setup is
 547        done when the starting point is either a local branch or remote
 548        branch. This option defaults to true.
 549
 550branch.autosetuprebase::
 551        When a new branch is created with 'git-branch' or 'git-checkout'
 552        that tracks another branch, this variable tells git to set
 553        up pull to rebase instead of merge (see "branch.<name>.rebase").
 554        When `never`, rebase is never automatically set to true.
 555        When `local`, rebase is set to true for tracked branches of
 556        other local branches.
 557        When `remote`, rebase is set to true for tracked branches of
 558        remote branches.
 559        When `always`, rebase will be set to true for all tracking
 560        branches.
 561        See "branch.autosetupmerge" for details on how to set up a
 562        branch to track another branch.
 563        This option defaults to never.
 564
 565branch.<name>.remote::
 566        When in branch <name>, it tells 'git-fetch' and 'git-push' which
 567        remote to fetch from/push to.  It defaults to `origin` if no remote is
 568        configured. `origin` is also used if you are not on any branch.
 569
 570branch.<name>.merge::
 571        Defines, together with branch.<name>.remote, the upstream branch
 572        for the given branch. It tells 'git-fetch'/'git-pull' which
 573        branch to merge and can also affect 'git-push' (see push.default).
 574        When in branch <name>, it tells 'git-fetch' the default
 575        refspec to be marked for merging in FETCH_HEAD. The value is
 576        handled like the remote part of a refspec, and must match a
 577        ref which is fetched from the remote given by
 578        "branch.<name>.remote".
 579        The merge information is used by 'git-pull' (which at first calls
 580        'git-fetch') to lookup the default branch for merging. Without
 581        this option, 'git-pull' defaults to merge the first refspec fetched.
 582        Specify multiple values to get an octopus merge.
 583        If you wish to setup 'git-pull' so that it merges into <name> from
 584        another branch in the local repository, you can point
 585        branch.<name>.merge to the desired branch, and use the special setting
 586        `.` (a period) for branch.<name>.remote.
 587
 588branch.<name>.mergeoptions::
 589        Sets default options for merging into branch <name>. The syntax and
 590        supported options are the same as those of linkgit:git-merge[1], but
 591        option values containing whitespace characters are currently not
 592        supported.
 593
 594branch.<name>.rebase::
 595        When true, rebase the branch <name> on top of the fetched branch,
 596        instead of merging the default branch from the default remote when
 597        "git pull" is run.
 598        *NOTE*: this is a possibly dangerous operation; do *not* use
 599        it unless you understand the implications (see linkgit:git-rebase[1]
 600        for details).
 601
 602browser.<tool>.cmd::
 603        Specify the command to invoke the specified browser. The
 604        specified command is evaluated in shell with the URLs passed
 605        as arguments. (See linkgit:git-web--browse[1].)
 606
 607browser.<tool>.path::
 608        Override the path for the given tool that may be used to
 609        browse HTML help (see '-w' option in linkgit:git-help[1]) or a
 610        working repository in gitweb (see linkgit:git-instaweb[1]).
 611
 612clean.requireForce::
 613        A boolean to make git-clean do nothing unless given -f
 614        or -n.   Defaults to true.
 615
 616color.branch::
 617        A boolean to enable/disable color in the output of
 618        linkgit:git-branch[1]. May be set to `always`,
 619        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 620        only when the output is to a terminal. Defaults to false.
 621
 622color.branch.<slot>::
 623        Use customized color for branch coloration. `<slot>` is one of
 624        `current` (the current branch), `local` (a local branch),
 625        `remote` (a tracking branch in refs/remotes/), `plain` (other
 626        refs).
 627+
 628The value for these configuration variables is a list of colors (at most
 629two) and attributes (at most one), separated by spaces.  The colors
 630accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`,
 631`magenta`, `cyan` and `white`; the attributes are `bold`, `dim`, `ul`,
 632`blink` and `reverse`.  The first color given is the foreground; the
 633second is the background.  The position of the attribute, if any,
 634doesn't matter.
 635
 636color.diff::
 637        When set to `always`, always use colors in patch.
 638        When false (or `never`), never.  When set to `true` or `auto`, use
 639        colors only when the output is to the terminal. Defaults to false.
 640
 641color.diff.<slot>::
 642        Use customized color for diff colorization.  `<slot>` specifies
 643        which part of the patch to use the specified color, and is one
 644        of `plain` (context text), `meta` (metainformation), `frag`
 645        (hunk header), 'func' (function in hunk header), `old` (removed lines),
 646        `new` (added lines), `commit` (commit headers), or `whitespace`
 647        (highlighting whitespace errors). The values of these variables may be
 648        specified as in color.branch.<slot>.
 649
 650color.grep::
 651        When set to `always`, always highlight matches.  When `false` (or
 652        `never`), never.  When set to `true` or `auto`, use color only
 653        when the output is written to the terminal.  Defaults to `false`.
 654
 655color.grep.external::
 656        The string value of this variable is passed to an external 'grep'
 657        command as a command line option if match highlighting is turned
 658        on.  If set to an empty string, no option is passed at all,
 659        turning off coloring for external 'grep' calls; this is the default.
 660        For GNU grep, set it to `--color=always` to highlight matches even
 661        when a pager is used.
 662
 663color.grep.match::
 664        Use customized color for matches.  The value of this variable
 665        may be specified as in color.branch.<slot>.  It is passed using
 666        the environment variables 'GREP_COLOR' and 'GREP_COLORS' when
 667        calling an external 'grep'.
 668
 669color.interactive::
 670        When set to `always`, always use colors for interactive prompts
 671        and displays (such as those used by "git-add --interactive").
 672        When false (or `never`), never.  When set to `true` or `auto`, use
 673        colors only when the output is to the terminal. Defaults to false.
 674
 675color.interactive.<slot>::
 676        Use customized color for 'git-add --interactive'
 677        output. `<slot>` may be `prompt`, `header`, `help` or `error`, for
 678        four distinct types of normal output from interactive
 679        commands.  The values of these variables may be specified as
 680        in color.branch.<slot>.
 681
 682color.pager::
 683        A boolean to enable/disable colored output when the pager is in
 684        use (default is true).
 685
 686color.showbranch::
 687        A boolean to enable/disable color in the output of
 688        linkgit:git-show-branch[1]. May be set to `always`,
 689        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 690        only when the output is to a terminal. Defaults to false.
 691
 692color.status::
 693        A boolean to enable/disable color in the output of
 694        linkgit:git-status[1]. May be set to `always`,
 695        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 696        only when the output is to a terminal. Defaults to false.
 697
 698color.status.<slot>::
 699        Use customized color for status colorization. `<slot>` is
 700        one of `header` (the header text of the status message),
 701        `added` or `updated` (files which are added but not committed),
 702        `changed` (files which are changed but not added in the index),
 703        `untracked` (files which are not tracked by git), or
 704        `nobranch` (the color the 'no branch' warning is shown in, defaulting
 705        to red). The values of these variables may be specified as in
 706        color.branch.<slot>.
 707
 708color.ui::
 709        When set to `always`, always use colors in all git commands which
 710        are capable of colored output. When false (or `never`), never. When
 711        set to `true` or `auto`, use colors only when the output is to the
 712        terminal. When more specific variables of color.* are set, they always
 713        take precedence over this setting. Defaults to false.
 714
 715commit.template::
 716        Specify a file to use as the template for new commit messages.
 717        "{tilde}/" is expanded to the value of `$HOME` and "{tilde}user/" to the
 718        specified user's home directory.
 719
 720diff.autorefreshindex::
 721        When using 'git-diff' to compare with work tree
 722        files, do not consider stat-only change as changed.
 723        Instead, silently run `git update-index --refresh` to
 724        update the cached stat information for paths whose
 725        contents in the work tree match the contents in the
 726        index.  This option defaults to true.  Note that this
 727        affects only 'git-diff' Porcelain, and not lower level
 728        'diff' commands, such as 'git-diff-files'.
 729
 730diff.external::
 731        If this config variable is set, diff generation is not
 732        performed using the internal diff machinery, but using the
 733        given command.  Can be overridden with the `GIT_EXTERNAL_DIFF'
 734        environment variable.  The command is called with parameters
 735        as described under "git Diffs" in linkgit:git[1].  Note: if
 736        you want to use an external diff program only on a subset of
 737        your files, you might want to use linkgit:gitattributes[5] instead.
 738
 739diff.mnemonicprefix::
 740        If set, 'git-diff' uses a prefix pair that is different from the
 741        standard "a/" and "b/" depending on what is being compared.  When
 742        this configuration is in effect, reverse diff output also swaps
 743        the order of the prefixes:
 744'git-diff';;
 745        compares the (i)ndex and the (w)ork tree;
 746'git-diff HEAD';;
 747         compares a (c)ommit and the (w)ork tree;
 748'git diff --cached';;
 749        compares a (c)ommit and the (i)ndex;
 750'git-diff HEAD:file1 file2';;
 751        compares an (o)bject and a (w)ork tree entity;
 752'git diff --no-index a b';;
 753        compares two non-git things (1) and (2).
 754
 755diff.renameLimit::
 756        The number of files to consider when performing the copy/rename
 757        detection; equivalent to the 'git-diff' option '-l'.
 758
 759diff.renames::
 760        Tells git to detect renames.  If set to any boolean value, it
 761        will enable basic rename detection.  If set to "copies" or
 762        "copy", it will detect copies, as well.
 763
 764diff.suppressBlankEmpty::
 765        A boolean to inhibit the standard behavior of printing a space
 766        before each empty output line. Defaults to false.
 767
 768diff.tool::
 769        Controls which diff tool is used.  `diff.tool` overrides
 770        `merge.tool` when used by linkgit:git-difftool[1] and has
 771        the same valid values as `merge.tool` minus "tortoisemerge"
 772        and plus "kompare".
 773
 774difftool.<tool>.path::
 775        Override the path for the given tool.  This is useful in case
 776        your tool is not in the PATH.
 777
 778difftool.<tool>.cmd::
 779        Specify the command to invoke the specified diff tool.
 780        The specified command is evaluated in shell with the following
 781        variables available:  'LOCAL' is set to the name of the temporary
 782        file containing the contents of the diff pre-image and 'REMOTE'
 783        is set to the name of the temporary file containing the contents
 784        of the diff post-image.
 785
 786difftool.prompt::
 787        Prompt before each invocation of the diff tool.
 788
 789diff.wordRegex::
 790        A POSIX Extended Regular Expression used to determine what is a "word"
 791        when performing word-by-word difference calculations.  Character
 792        sequences that match the regular expression are "words", all other
 793        characters are *ignorable* whitespace.
 794
 795fetch.unpackLimit::
 796        If the number of objects fetched over the git native
 797        transfer is below this
 798        limit, then the objects will be unpacked into loose object
 799        files. However if the number of received objects equals or
 800        exceeds this limit then the received pack will be stored as
 801        a pack, after adding any missing delta bases.  Storing the
 802        pack from a push can make the push operation complete faster,
 803        especially on slow filesystems.  If not set, the value of
 804        `transfer.unpackLimit` is used instead.
 805
 806format.attach::
 807        Enable multipart/mixed attachments as the default for
 808        'format-patch'.  The value can also be a double quoted string
 809        which will enable attachments as the default and set the
 810        value as the boundary.  See the --attach option in
 811        linkgit:git-format-patch[1].
 812
 813format.numbered::
 814        A boolean which can enable or disable sequence numbers in patch
 815        subjects.  It defaults to "auto" which enables it only if there
 816        is more than one patch.  It can be enabled or disabled for all
 817        messages by setting it to "true" or "false".  See --numbered
 818        option in linkgit:git-format-patch[1].
 819
 820format.headers::
 821        Additional email headers to include in a patch to be submitted
 822        by mail.  See linkgit:git-format-patch[1].
 823
 824format.cc::
 825        Additional "Cc:" headers to include in a patch to be submitted
 826        by mail.  See the --cc option in linkgit:git-format-patch[1].
 827
 828format.subjectprefix::
 829        The default for format-patch is to output files with the '[PATCH]'
 830        subject prefix. Use this variable to change that prefix.
 831
 832format.suffix::
 833        The default for format-patch is to output files with the suffix
 834        `.patch`. Use this variable to change that suffix (make sure to
 835        include the dot if you want it).
 836
 837format.pretty::
 838        The default pretty format for log/show/whatchanged command,
 839        See linkgit:git-log[1], linkgit:git-show[1],
 840        linkgit:git-whatchanged[1].
 841
 842format.thread::
 843        The default threading style for 'git-format-patch'.  Can be
 844        either a boolean value, `shallow` or `deep`.  `shallow`
 845        threading makes every mail a reply to the head of the series,
 846        where the head is chosen from the cover letter, the
 847        `\--in-reply-to`, and the first patch mail, in this order.
 848        `deep` threading makes every mail a reply to the previous one.
 849        A true boolean value is the same as `shallow`, and a false
 850        value disables threading.
 851
 852format.signoff::
 853    A boolean value which lets you enable the `-s/--signoff` option of
 854    format-patch by default. *Note:* Adding the Signed-off-by: line to a
 855    patch should be a conscious act and means that you certify you have
 856    the rights to submit this work under the same open source license.
 857    Please see the 'SubmittingPatches' document for further discussion.
 858
 859gc.aggressiveWindow::
 860        The window size parameter used in the delta compression
 861        algorithm used by 'git-gc --aggressive'.  This defaults
 862        to 10.
 863
 864gc.auto::
 865        When there are approximately more than this many loose
 866        objects in the repository, `git gc --auto` will pack them.
 867        Some Porcelain commands use this command to perform a
 868        light-weight garbage collection from time to time.  The
 869        default value is 6700.  Setting this to 0 disables it.
 870
 871gc.autopacklimit::
 872        When there are more than this many packs that are not
 873        marked with `*.keep` file in the repository, `git gc
 874        --auto` consolidates them into one larger pack.  The
 875        default value is 50.  Setting this to 0 disables it.
 876
 877gc.packrefs::
 878        'git-gc' does not run `git pack-refs` in a bare repository by
 879        default so that older dumb-transport clients can still fetch
 880        from the repository.  Setting this to `true` lets 'git-gc'
 881        to run `git pack-refs`.  Setting this to `false` tells
 882        'git-gc' never to run `git pack-refs`. The default setting is
 883        `notbare`. Enable it only when you know you do not have to
 884        support such clients.  The default setting will change to `true`
 885        at some stage, and setting this to `false` will continue to
 886        prevent `git pack-refs` from being run from 'git-gc'.
 887
 888gc.pruneexpire::
 889        When 'git-gc' is run, it will call 'prune --expire 2.weeks.ago'.
 890        Override the grace period with this config variable.  The value
 891        "now" may be used to disable this  grace period and always prune
 892        unreachable objects immediately.
 893
 894gc.reflogexpire::
 895        'git-reflog expire' removes reflog entries older than
 896        this time; defaults to 90 days.
 897
 898gc.reflogexpireunreachable::
 899        'git-reflog expire' removes reflog entries older than
 900        this time and are not reachable from the current tip;
 901        defaults to 30 days.
 902
 903gc.rerereresolved::
 904        Records of conflicted merge you resolved earlier are
 905        kept for this many days when 'git-rerere gc' is run.
 906        The default is 60 days.  See linkgit:git-rerere[1].
 907
 908gc.rerereunresolved::
 909        Records of conflicted merge you have not resolved are
 910        kept for this many days when 'git-rerere gc' is run.
 911        The default is 15 days.  See linkgit:git-rerere[1].
 912
 913gitcvs.commitmsgannotation::
 914        Append this string to each commit message. Set to empty string
 915        to disable this feature. Defaults to "via git-CVS emulator".
 916
 917gitcvs.enabled::
 918        Whether the CVS server interface is enabled for this repository.
 919        See linkgit:git-cvsserver[1].
 920
 921gitcvs.logfile::
 922        Path to a log file where the CVS server interface well... logs
 923        various stuff. See linkgit:git-cvsserver[1].
 924
 925gitcvs.usecrlfattr::
 926        If true, the server will look up the `crlf` attribute for
 927        files to determine the '-k' modes to use. If `crlf` is set,
 928        the '-k' mode will be left blank, so cvs clients will
 929        treat it as text. If `crlf` is explicitly unset, the file
 930        will be set with '-kb' mode, which suppresses any newline munging
 931        the client might otherwise do. If `crlf` is not specified,
 932        then 'gitcvs.allbinary' is used. See linkgit:gitattributes[5].
 933
 934gitcvs.allbinary::
 935        This is used if 'gitcvs.usecrlfattr' does not resolve
 936        the correct '-kb' mode to use. If true, all
 937        unresolved files are sent to the client in
 938        mode '-kb'. This causes the client to treat them
 939        as binary files, which suppresses any newline munging it
 940        otherwise might do. Alternatively, if it is set to "guess",
 941        then the contents of the file are examined to decide if
 942        it is binary, similar to 'core.autocrlf'.
 943
 944gitcvs.dbname::
 945        Database used by git-cvsserver to cache revision information
 946        derived from the git repository. The exact meaning depends on the
 947        used database driver, for SQLite (which is the default driver) this
 948        is a filename. Supports variable substitution (see
 949        linkgit:git-cvsserver[1] for details). May not contain semicolons (`;`).
 950        Default: '%Ggitcvs.%m.sqlite'
 951
 952gitcvs.dbdriver::
 953        Used Perl DBI driver. You can specify any available driver
 954        for this here, but it might not work. git-cvsserver is tested
 955        with 'DBD::SQLite', reported to work with 'DBD::Pg', and
 956        reported *not* to work with 'DBD::mysql'. Experimental feature.
 957        May not contain double colons (`:`). Default: 'SQLite'.
 958        See linkgit:git-cvsserver[1].
 959
 960gitcvs.dbuser, gitcvs.dbpass::
 961        Database user and password. Only useful if setting 'gitcvs.dbdriver',
 962        since SQLite has no concept of database users and/or passwords.
 963        'gitcvs.dbuser' supports variable substitution (see
 964        linkgit:git-cvsserver[1] for details).
 965
 966gitcvs.dbTableNamePrefix::
 967        Database table name prefix.  Prepended to the names of any
 968        database tables used, allowing a single database to be used
 969        for several repositories.  Supports variable substitution (see
 970        linkgit:git-cvsserver[1] for details).  Any non-alphabetic
 971        characters will be replaced with underscores.
 972
 973All gitcvs variables except for 'gitcvs.usecrlfattr' and
 974'gitcvs.allbinary' can also be specified as
 975'gitcvs.<access_method>.<varname>' (where 'access_method'
 976is one of "ext" and "pserver") to make them apply only for the given
 977access method.
 978
 979gui.commitmsgwidth::
 980        Defines how wide the commit message window is in the
 981        linkgit:git-gui[1]. "75" is the default.
 982
 983gui.diffcontext::
 984        Specifies how many context lines should be used in calls to diff
 985        made by the linkgit:git-gui[1]. The default is "5".
 986
 987gui.encoding::
 988        Specifies the default encoding to use for displaying of
 989        file contents in linkgit:git-gui[1] and linkgit:gitk[1].
 990        It can be overridden by setting the 'encoding' attribute
 991        for relevant files (see linkgit:gitattributes[5]).
 992        If this option is not set, the tools default to the
 993        locale encoding.
 994
 995gui.matchtrackingbranch::
 996        Determines if new branches created with linkgit:git-gui[1] should
 997        default to tracking remote branches with matching names or
 998        not. Default: "false".
 999
1000gui.newbranchtemplate::
1001        Is used as suggested name when creating new branches using the
1002        linkgit:git-gui[1].
1003
1004gui.pruneduringfetch::
1005        "true" if linkgit:git-gui[1] should prune tracking branches when
1006        performing a fetch. The default value is "false".
1007
1008gui.trustmtime::
1009        Determines if linkgit:git-gui[1] should trust the file modification
1010        timestamp or not. By default the timestamps are not trusted.
1011
1012gui.spellingdictionary::
1013        Specifies the dictionary used for spell checking commit messages in
1014        the linkgit:git-gui[1]. When set to "none" spell checking is turned
1015        off.
1016
1017gui.fastcopyblame::
1018        If true, 'git gui blame' uses '-C' instead of '-C -C' for original
1019        location detection. It makes blame significantly faster on huge
1020        repositories at the expense of less thorough copy detection.
1021
1022gui.copyblamethreshold::
1023        Specifies the threshold to use in 'git gui blame' original location
1024        detection, measured in alphanumeric characters. See the
1025        linkgit:git-blame[1] manual for more information on copy detection.
1026
1027gui.blamehistoryctx::
1028        Specifies the radius of history context in days to show in
1029        linkgit:gitk[1] for the selected commit, when the `Show History
1030        Context` menu item is invoked from 'git gui blame'. If this
1031        variable is set to zero, the whole history is shown.
1032
1033guitool.<name>.cmd::
1034        Specifies the shell command line to execute when the corresponding item
1035        of the linkgit:git-gui[1] `Tools` menu is invoked. This option is
1036        mandatory for every tool. The command is executed from the root of
1037        the working directory, and in the environment it receives the name of
1038        the tool as 'GIT_GUITOOL', the name of the currently selected file as
1039        'FILENAME', and the name of the current branch as 'CUR_BRANCH' (if
1040        the head is detached, 'CUR_BRANCH' is empty).
1041
1042guitool.<name>.needsfile::
1043        Run the tool only if a diff is selected in the GUI. It guarantees
1044        that 'FILENAME' is not empty.
1045
1046guitool.<name>.noconsole::
1047        Run the command silently, without creating a window to display its
1048        output.
1049
1050guitool.<name>.norescan::
1051        Don't rescan the working directory for changes after the tool
1052        finishes execution.
1053
1054guitool.<name>.confirm::
1055        Show a confirmation dialog before actually running the tool.
1056
1057guitool.<name>.argprompt::
1058        Request a string argument from the user, and pass it to the tool
1059        through the 'ARGS' environment variable. Since requesting an
1060        argument implies confirmation, the 'confirm' option has no effect
1061        if this is enabled. If the option is set to 'true', 'yes', or '1',
1062        the dialog uses a built-in generic prompt; otherwise the exact
1063        value of the variable is used.
1064
1065guitool.<name>.revprompt::
1066        Request a single valid revision from the user, and set the
1067        'REVISION' environment variable. In other aspects this option
1068        is similar to 'argprompt', and can be used together with it.
1069
1070guitool.<name>.revunmerged::
1071        Show only unmerged branches in the 'revprompt' subdialog.
1072        This is useful for tools similar to merge or rebase, but not
1073        for things like checkout or reset.
1074
1075guitool.<name>.title::
1076        Specifies the title to use for the prompt dialog. The default
1077        is the tool name.
1078
1079guitool.<name>.prompt::
1080        Specifies the general prompt string to display at the top of
1081        the dialog, before subsections for 'argprompt' and 'revprompt'.
1082        The default value includes the actual command.
1083
1084help.browser::
1085        Specify the browser that will be used to display help in the
1086        'web' format. See linkgit:git-help[1].
1087
1088help.format::
1089        Override the default help format used by linkgit:git-help[1].
1090        Values 'man', 'info', 'web' and 'html' are supported. 'man' is
1091        the default. 'web' and 'html' are the same.
1092
1093help.autocorrect::
1094        Automatically correct and execute mistyped commands after
1095        waiting for the given number of deciseconds (0.1 sec). If more
1096        than one command can be deduced from the entered text, nothing
1097        will be executed.  If the value of this option is negative,
1098        the corrected command will be executed immediately. If the
1099        value is 0 - the command will be just shown but not executed.
1100        This is the default.
1101
1102http.proxy::
1103        Override the HTTP proxy, normally configured using the 'http_proxy'
1104        environment variable (see linkgit:curl[1]).  This can be overridden
1105        on a per-remote basis; see remote.<name>.proxy
1106
1107http.sslVerify::
1108        Whether to verify the SSL certificate when fetching or pushing
1109        over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
1110        variable.
1111
1112http.sslCert::
1113        File containing the SSL certificate when fetching or pushing
1114        over HTTPS. Can be overridden by the 'GIT_SSL_CERT' environment
1115        variable.
1116
1117http.sslKey::
1118        File containing the SSL private key when fetching or pushing
1119        over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment
1120        variable.
1121
1122http.sslCertPasswordProtected::
1123        Enable git's password prompt for the SSL certificate.  Otherwise
1124        OpenSSL will prompt the user, possibly many times, if the
1125        certificate or private key is encrypted.  Can be overridden by the
1126        'GIT_SSL_CERT_PASSWORD_PROTECTED' environment variable.
1127
1128http.sslCAInfo::
1129        File containing the certificates to verify the peer with when
1130        fetching or pushing over HTTPS. Can be overridden by the
1131        'GIT_SSL_CAINFO' environment variable.
1132
1133http.sslCAPath::
1134        Path containing files with the CA certificates to verify the peer
1135        with when fetching or pushing over HTTPS. Can be overridden
1136        by the 'GIT_SSL_CAPATH' environment variable.
1137
1138http.maxRequests::
1139        How many HTTP requests to launch in parallel. Can be overridden
1140        by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5.
1141
1142http.postBuffer::
1143        Maximum size in bytes of the buffer used by smart HTTP
1144        transports when POSTing data to the remote system.
1145        For requests larger than this buffer size, HTTP/1.1 and
1146        Transfer-Encoding: chunked is used to avoid creating a
1147        massive pack file locally.  Default is 1 MiB, which is
1148        sufficient for most requests.
1149
1150http.lowSpeedLimit, http.lowSpeedTime::
1151        If the HTTP transfer speed is less than 'http.lowSpeedLimit'
1152        for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
1153        Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and
1154        'GIT_HTTP_LOW_SPEED_TIME' environment variables.
1155
1156http.noEPSV::
1157        A boolean which disables using of EPSV ftp command by curl.
1158        This can helpful with some "poor" ftp servers which don't
1159        support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
1160        environment variable. Default is false (curl will use EPSV).
1161
1162i18n.commitEncoding::
1163        Character encoding the commit messages are stored in; git itself
1164        does not care per se, but this information is necessary e.g. when
1165        importing commits from emails or in the gitk graphical history
1166        browser (and possibly at other places in the future or in other
1167        porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.
1168
1169i18n.logOutputEncoding::
1170        Character encoding the commit messages are converted to when
1171        running 'git-log' and friends.
1172
1173imap::
1174        The configuration variables in the 'imap' section are described
1175        in linkgit:git-imap-send[1].
1176
1177instaweb.browser::
1178        Specify the program that will be used to browse your working
1179        repository in gitweb. See linkgit:git-instaweb[1].
1180
1181instaweb.httpd::
1182        The HTTP daemon command-line to start gitweb on your working
1183        repository. See linkgit:git-instaweb[1].
1184
1185instaweb.local::
1186        If true the web server started by linkgit:git-instaweb[1] will
1187        be bound to the local IP (127.0.0.1).
1188
1189instaweb.modulepath::
1190        The module path for an apache httpd used by linkgit:git-instaweb[1].
1191
1192instaweb.port::
1193        The port number to bind the gitweb httpd to. See
1194        linkgit:git-instaweb[1].
1195
1196interactive.singlekey::
1197        In interactive commands, allow the user to provide one-letter
1198        input with a single key (i.e., without hitting enter).
1199        Currently this is used only by the `\--patch` mode of
1200        linkgit:git-add[1].  Note that this setting is silently
1201        ignored if portable keystroke input is not available.
1202
1203log.date::
1204        Set default date-time mode for the log command. Setting log.date
1205        value is similar to using 'git-log'\'s --date option. The value is one of the
1206        following alternatives: {relative,local,default,iso,rfc,short}.
1207        See linkgit:git-log[1].
1208
1209log.showroot::
1210        If true, the initial commit will be shown as a big creation event.
1211        This is equivalent to a diff against an empty tree.
1212        Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
1213        normally hide the root commit will now show it. True by default.
1214
1215mailmap.file::
1216        The location of an augmenting mailmap file. The default
1217        mailmap, located in the root of the repository, is loaded
1218        first, then the mailmap file pointed to by this variable.
1219        The location of the mailmap file may be in a repository
1220        subdirectory, or somewhere outside of the repository itself.
1221        See linkgit:git-shortlog[1] and linkgit:git-blame[1].
1222
1223man.viewer::
1224        Specify the programs that may be used to display help in the
1225        'man' format. See linkgit:git-help[1].
1226
1227man.<tool>.cmd::
1228        Specify the command to invoke the specified man viewer. The
1229        specified command is evaluated in shell with the man page
1230        passed as argument. (See linkgit:git-help[1].)
1231
1232man.<tool>.path::
1233        Override the path for the given tool that may be used to
1234        display help in the 'man' format. See linkgit:git-help[1].
1235
1236include::merge-config.txt[]
1237
1238mergetool.<tool>.path::
1239        Override the path for the given tool.  This is useful in case
1240        your tool is not in the PATH.
1241
1242mergetool.<tool>.cmd::
1243        Specify the command to invoke the specified merge tool.  The
1244        specified command is evaluated in shell with the following
1245        variables available: 'BASE' is the name of a temporary file
1246        containing the common base of the files to be merged, if available;
1247        'LOCAL' is the name of a temporary file containing the contents of
1248        the file on the current branch; 'REMOTE' is the name of a temporary
1249        file containing the contents of the file from the branch being
1250        merged; 'MERGED' contains the name of the file to which the merge
1251        tool should write the results of a successful merge.
1252
1253mergetool.<tool>.trustExitCode::
1254        For a custom merge command, specify whether the exit code of
1255        the merge command can be used to determine whether the merge was
1256        successful.  If this is not set to true then the merge target file
1257        timestamp is checked and the merge assumed to have been successful
1258        if the file has been updated, otherwise the user is prompted to
1259        indicate the success of the merge.
1260
1261mergetool.keepBackup::
1262        After performing a merge, the original file with conflict markers
1263        can be saved as a file with a `.orig` extension.  If this variable
1264        is set to `false` then this file is not preserved.  Defaults to
1265        `true` (i.e. keep the backup files).
1266
1267mergetool.keepTemporaries::
1268        When invoking a custom merge tool, git uses a set of temporary
1269        files to pass to the tool. If the tool returns an error and this
1270        variable is set to `true`, then these temporary files will be
1271        preserved, otherwise they will be removed after the tool has
1272        exited. Defaults to `false`.
1273
1274mergetool.prompt::
1275        Prompt before each invocation of the merge resolution program.
1276
1277pack.window::
1278        The size of the window used by linkgit:git-pack-objects[1] when no
1279        window size is given on the command line. Defaults to 10.
1280
1281pack.depth::
1282        The maximum delta depth used by linkgit:git-pack-objects[1] when no
1283        maximum depth is given on the command line. Defaults to 50.
1284
1285pack.windowMemory::
1286        The window memory size limit used by linkgit:git-pack-objects[1]
1287        when no limit is given on the command line.  The value can be
1288        suffixed with "k", "m", or "g".  Defaults to 0, meaning no
1289        limit.
1290
1291pack.compression::
1292        An integer -1..9, indicating the compression level for objects
1293        in a pack file. -1 is the zlib default. 0 means no
1294        compression, and 1..9 are various speed/size tradeoffs, 9 being
1295        slowest.  If not set,  defaults to core.compression.  If that is
1296        not set,  defaults to -1, the zlib default, which is "a default
1297        compromise between speed and compression (currently equivalent
1298        to level 6)."
1299
1300pack.deltaCacheSize::
1301        The maximum memory in bytes used for caching deltas in
1302        linkgit:git-pack-objects[1] before writing them out to a pack.
1303        This cache is used to speed up the writing object phase by not
1304        having to recompute the final delta result once the best match
1305        for all objects is found.  Repacking large repositories on machines
1306        which are tight with memory might be badly impacted by this though,
1307        especially if this cache pushes the system into swapping.
1308        A value of 0 means no limit. The smallest size of 1 byte may be
1309        used to virtually disable this cache. Defaults to 256 MiB.
1310
1311pack.deltaCacheLimit::
1312        The maximum size of a delta, that is cached in
1313        linkgit:git-pack-objects[1]. This cache is used to speed up the
1314        writing object phase by not having to recompute the final delta
1315        result once the best match for all objects is found. Defaults to 1000.
1316
1317pack.threads::
1318        Specifies the number of threads to spawn when searching for best
1319        delta matches.  This requires that linkgit:git-pack-objects[1]
1320        be compiled with pthreads otherwise this option is ignored with a
1321        warning. This is meant to reduce packing time on multiprocessor
1322        machines. The required amount of memory for the delta search window
1323        is however multiplied by the number of threads.
1324        Specifying 0 will cause git to auto-detect the number of CPU's
1325        and set the number of threads accordingly.
1326
1327pack.indexVersion::
1328        Specify the default pack index version.  Valid values are 1 for
1329        legacy pack index used by Git versions prior to 1.5.2, and 2 for
1330        the new pack index with capabilities for packs larger than 4 GB
1331        as well as proper protection against the repacking of corrupted
1332        packs.  Version 2 is the default.  Note that version 2 is enforced
1333        and this config option ignored whenever the corresponding pack is
1334        larger than 2 GB.
1335+
1336If you have an old git that does not understand the version 2 `{asterisk}.idx` file,
1337cloning or fetching over a non native protocol (e.g. "http" and "rsync")
1338that will copy both `{asterisk}.pack` file and corresponding `{asterisk}.idx` file from the
1339other side may give you a repository that cannot be accessed with your
1340older version of git. If the `{asterisk}.pack` file is smaller than 2 GB, however,
1341you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
1342the `{asterisk}.idx` file.
1343
1344pack.packSizeLimit::
1345        The default maximum size of a pack.  This setting only affects
1346        packing to a file, i.e. the git:// protocol is unaffected.  It
1347        can be overridden by the `\--max-pack-size` option of
1348        linkgit:git-repack[1].
1349
1350pager.<cmd>::
1351        Allows turning on or off pagination of the output of a
1352        particular git subcommand when writing to a tty.  If
1353        `\--paginate` or `\--no-pager` is specified on the command line,
1354        it takes precedence over this option.  To disable pagination for
1355        all commands, set `core.pager` or `GIT_PAGER` to `cat`.
1356
1357pull.octopus::
1358        The default merge strategy to use when pulling multiple branches
1359        at once.
1360
1361pull.twohead::
1362        The default merge strategy to use when pulling a single branch.
1363
1364push.default::
1365        Defines the action git push should take if no refspec is given
1366        on the command line, no refspec is configured in the remote, and
1367        no refspec is implied by any of the options given on the command
1368        line. Possible values are:
1369+
1370* `nothing` do not push anything.
1371* `matching` push all matching branches.
1372  All branches having the same name in both ends are considered to be
1373  matching. This is the default.
1374* `tracking` push the current branch to its upstream branch.
1375* `current` push the current branch to a branch of the same name.
1376
1377rebase.stat::
1378        Whether to show a diffstat of what changed upstream since the last
1379        rebase. False by default.
1380
1381receive.autogc::
1382        By default, git-receive-pack will run "git-gc --auto" after
1383        receiving data from git-push and updating refs.  You can stop
1384        it by setting this variable to false.
1385
1386receive.fsckObjects::
1387        If it is set to true, git-receive-pack will check all received
1388        objects. It will abort in the case of a malformed object or a
1389        broken link. The result of an abort are only dangling objects.
1390        Defaults to false.
1391
1392receive.unpackLimit::
1393        If the number of objects received in a push is below this
1394        limit then the objects will be unpacked into loose object
1395        files. However if the number of received objects equals or
1396        exceeds this limit then the received pack will be stored as
1397        a pack, after adding any missing delta bases.  Storing the
1398        pack from a push can make the push operation complete faster,
1399        especially on slow filesystems.  If not set, the value of
1400        `transfer.unpackLimit` is used instead.
1401
1402receive.denyDeletes::
1403        If set to true, git-receive-pack will deny a ref update that deletes
1404        the ref. Use this to prevent such a ref deletion via a push.
1405
1406receive.denyCurrentBranch::
1407        If set to true or "refuse", receive-pack will deny a ref update
1408        to the currently checked out branch of a non-bare repository.
1409        Such a push is potentially dangerous because it brings the HEAD
1410        out of sync with the index and working tree. If set to "warn",
1411        print a warning of such a push to stderr, but allow the push to
1412        proceed. If set to false or "ignore", allow such pushes with no
1413        message. Defaults to "warn".
1414
1415receive.denyNonFastForwards::
1416        If set to true, git-receive-pack will deny a ref update which is
1417        not a fast-forward. Use this to prevent such an update via a push,
1418        even if that push is forced. This configuration variable is
1419        set when initializing a shared repository.
1420
1421receive.updateserverinfo::
1422        If set to true, git-receive-pack will run git-update-server-info
1423        after receiving data from git-push and updating refs.
1424
1425remote.<name>.url::
1426        The URL of a remote repository.  See linkgit:git-fetch[1] or
1427        linkgit:git-push[1].
1428
1429remote.<name>.pushurl::
1430        The push URL of a remote repository.  See linkgit:git-push[1].
1431
1432remote.<name>.proxy::
1433        For remotes that require curl (http, https and ftp), the URL to
1434        the proxy to use for that remote.  Set to the empty string to
1435        disable proxying for that remote.
1436
1437remote.<name>.fetch::
1438        The default set of "refspec" for linkgit:git-fetch[1]. See
1439        linkgit:git-fetch[1].
1440
1441remote.<name>.push::
1442        The default set of "refspec" for linkgit:git-push[1]. See
1443        linkgit:git-push[1].
1444
1445remote.<name>.mirror::
1446        If true, pushing to this remote will automatically behave
1447        as if the `\--mirror` option was given on the command line.
1448
1449remote.<name>.skipDefaultUpdate::
1450        If true, this remote will be skipped by default when updating
1451        using linkgit:git-fetch[1] or the `update` subcommand of
1452        linkgit:git-remote[1].
1453
1454remote.<name>.skipFetchAll::
1455        If true, this remote will be skipped by default when updating
1456        using linkgit:git-fetch[1] or the `update` subcommand of
1457        linkgit:git-remote[1].
1458
1459remote.<name>.receivepack::
1460        The default program to execute on the remote side when pushing.  See
1461        option \--receive-pack of linkgit:git-push[1].
1462
1463remote.<name>.uploadpack::
1464        The default program to execute on the remote side when fetching.  See
1465        option \--upload-pack of linkgit:git-fetch-pack[1].
1466
1467remote.<name>.tagopt::
1468        Setting this value to \--no-tags disables automatic tag following when
1469        fetching from remote <name>
1470
1471remote.<name>.vcs::
1472        Setting this to a value <vcs> will cause git to interact with
1473        the remote with the git-remote-<vcs> helper.
1474
1475remotes.<group>::
1476        The list of remotes which are fetched by "git remote update
1477        <group>".  See linkgit:git-remote[1].
1478
1479repack.usedeltabaseoffset::
1480        By default, linkgit:git-repack[1] creates packs that use
1481        delta-base offset. If you need to share your repository with
1482        git older than version 1.4.4, either directly or via a dumb
1483        protocol such as http, then you need to set this option to
1484        "false" and repack. Access from old git versions over the
1485        native protocol are unaffected by this option.
1486
1487rerere.autoupdate::
1488        When set to true, `git-rerere` updates the index with the
1489        resulting contents after it cleanly resolves conflicts using
1490        previously recorded resolution.  Defaults to false.
1491
1492rerere.enabled::
1493        Activate recording of resolved conflicts, so that identical
1494        conflict hunks can be resolved automatically, should they
1495        be encountered again.  linkgit:git-rerere[1] command is by
1496        default enabled if you create `rr-cache` directory under
1497        `$GIT_DIR`, but can be disabled by setting this option to false.
1498
1499sendemail.identity::
1500        A configuration identity. When given, causes values in the
1501        'sendemail.<identity>' subsection to take precedence over
1502        values in the 'sendemail' section. The default identity is
1503        the value of 'sendemail.identity'.
1504
1505sendemail.smtpencryption::
1506        See linkgit:git-send-email[1] for description.  Note that this
1507        setting is not subject to the 'identity' mechanism.
1508
1509sendemail.smtpssl::
1510        Deprecated alias for 'sendemail.smtpencryption = ssl'.
1511
1512sendemail.<identity>.*::
1513        Identity-specific versions of the 'sendemail.*' parameters
1514        found below, taking precedence over those when the this
1515        identity is selected, through command-line or
1516        'sendemail.identity'.
1517
1518sendemail.aliasesfile::

1540sendemail.signedoffcc::
1541        Deprecated alias for 'sendemail.signedoffbycc'.
1542
1543showbranch.default::
1544        The default set of branches for linkgit:git-show-branch[1].
1545        See linkgit:git-show-branch[1].
1546
1547status.relativePaths::
1548        By default, linkgit:git-status[1] shows paths relative to the
1549        current directory. Setting this variable to `false` shows paths
1550        relative to the repository root (this was the default for git
1551        prior to v1.5.4).
1552
1553status.showUntrackedFiles::
1554        By default, linkgit:git-status[1] and linkgit:git-commit[1] show
1555        files which are not currently tracked by Git. Directories which
1556        contain only untracked files, are shown with the directory name
1557        only. Showing untracked files means that Git needs to lstat() all
1558        all the files in the whole repository, which might be slow on some
1559        systems. So, this variable controls how the commands displays
1560        the untracked files. Possible values are:
1561+
1562--
1563        - 'no'     - Show no untracked files
1564        - 'normal' - Shows untracked files and directories
1565        - 'all'    - Shows also individual files in untracked directories.
1566--
1567+
1568If this variable is not specified, it defaults to 'normal'.
1569This variable can be overridden with the -u|--untracked-files option
1570of linkgit:git-status[1] and linkgit:git-commit[1].
1571
1572tar.umask::
1573        This variable can be used to restrict the permission bits of
1574        tar archive entries.  The default is 0002, which turns off the
1575        world write bit.  The special value "user" indicates that the
1576        archiving user's umask will be used instead.  See umask(2) and
1577        linkgit:git-archive[1].
1578
1579transfer.unpackLimit::
1580        When `fetch.unpackLimit` or `receive.unpackLimit` are
1581        not set, the value of this variable is used instead.
1582        The default value is 100.
1583
1584url.<base>.insteadOf::
1585        Any URL that starts with this value will be rewritten to
1586        start, instead, with <base>. In cases where some site serves a
1587        large number of repositories, and serves them with multiple
1588        access methods, and some users need to use different access
1589        methods, this feature allows people to specify any of the
1590        equivalent URLs and have git automatically rewrite the URL to
1591        the best alternative for the particular user, even for a
1592        never-before-seen repository on the site.  When more than one
1593        insteadOf strings match a given URL, the longest match is used.
1594
1595url.<base>.pushInsteadOf::
1596        Any URL that starts with this value will not be pushed to;
1597        instead, it will be rewritten to start with <base>, and the
1598        resulting URL will be pushed to. In cases where some site serves
1599        a large number of repositories, and serves them with multiple
1600        access methods, some of which do not allow push, this feature
1601        allows people to specify a pull-only URL and have git
1602        automatically use an appropriate URL to push, even for a
1603        never-before-seen repository on the site.  When more than one
1604        pushInsteadOf strings match a given URL, the longest match is
1605        used.  If a remote has an explicit pushurl, git will ignore this
1606        setting for that remote.
1607
1608user.email::
1609        Your email address to be recorded in any newly created commits.
1610        Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and
1611        'EMAIL' environment variables.  See linkgit:git-commit-tree[1].
1612
1613user.name::
1614        Your full name to be recorded in any newly created commits.
1615        Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
1616        environment variables.  See linkgit:git-commit-tree[1].
1617
1618user.signingkey::
1619        If linkgit:git-tag[1] is not selecting the key you want it to
1620        automatically when creating a signed tag, you can override the
1621        default selection with this variable.  This option is passed
1622        unchanged to gpg's --local-user parameter, so you may specify a key
1623        using any method that gpg supports.
1624
1625web.browser::
1626        Specify a web browser that may be used by some commands.
1627        Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
1628        may use it.
