   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        resolveConflict::
 134                Advices shown by various commands when conflicts
 135                prevent the operation from being performed.
 136                Default: true.
 137        implicitIdentity::
 138                Advice on how to set your identity configuration when
 139                your information is guessed from the system username and
 140                domain name. Default: true.
 141
 142        detachedHead::
 143                Advice shown when you used linkgit::git-checkout[1] to
 144                move to the detach HEAD state, to instruct how to create
 145                a local branch after the fact.  Default: true.
 146--
 147
 148core.fileMode::
 149        If false, the executable bit differences between the index and
 150        the working copy are ignored; useful on broken filesystems like FAT.
 151        See linkgit:git-update-index[1].
 152+
 153The default is true, except linkgit:git-clone[1] or linkgit:git-init[1]
 154will probe and set core.fileMode false if appropriate when the
 155repository is created.
 156
 157core.ignoreCygwinFSTricks::
 158        This option is only used by Cygwin implementation of Git. If false,
 159        the Cygwin stat() and lstat() functions are used. This may be useful
 160        if your repository consists of a few separate directories joined in
 161        one hierarchy using Cygwin mount. If true, Git uses native Win32 API
 162        whenever it is possible and falls back to Cygwin functions only to
 163        handle symbol links. The native mode is more than twice faster than
 164        normal Cygwin l/stat() functions. True by default, unless core.filemode
 165        is true, in which case ignoreCygwinFSTricks is ignored as Cygwin's
 166        POSIX emulation is required to support core.filemode.
 167
 168core.ignorecase::
 169        If true, this option enables various workarounds to enable
 170        git to work better on filesystems that are not case sensitive,
 171        like FAT. For example, if a directory listing finds
 172        "makefile" when git expects "Makefile", git will assume
 173        it is really the same file, and continue to remember it as
 174        "Makefile".
 175+
 176The default is false, except linkgit:git-clone[1] or linkgit:git-init[1]
 177will probe and set core.ignorecase true if appropriate when the repository
 178is created.
 179
 180core.trustctime::
 181        If false, the ctime differences between the index and the
 182        working copy are ignored; useful when the inode change time
 183        is regularly modified by something outside Git (file system
 184        crawlers and some backup systems).
 185        See linkgit:git-update-index[1]. True by default.
 186
 187core.quotepath::
 188        The commands that output paths (e.g. 'ls-files',
 189        'diff'), when not given the `-z` option, will quote
 190        "unusual" characters in the pathname by enclosing the
 191        pathname in a double-quote pair and with backslashes the
 192        same way strings in C source code are quoted.  If this
 193        variable is set to false, the bytes higher than 0x80 are
 194        not quoted but output as verbatim.  Note that double
 195        quote, backslash and control characters are always
 196        quoted without `-z` regardless of the setting of this
 197        variable.
 198
 199core.autocrlf::
 200        If true, makes git convert `CRLF` at the end of lines in text files to
 201        `LF` when reading from the work tree, and convert in reverse when
 202        writing to the work tree.  The variable can be set to
 203        'input', in which case the conversion happens only while
 204        reading from the work tree but files are written out to the work
 205        tree with `LF` at the end of lines.  A file is considered
 206        "text" (i.e. be subjected to the autocrlf mechanism) based on
 207        the file's `crlf` attribute, or if `crlf` is unspecified,
 208        based on the file's contents.  See linkgit:gitattributes[5].
 209
 210core.safecrlf::
 211        If true, makes git check if converting `CRLF` as controlled by
 212        `core.autocrlf` is reversible.  Git will verify if a command
 213        modifies a file in the work tree either directly or indirectly.
 214        For example, committing a file followed by checking out the
 215        same file should yield the original file in the work tree.  If
 216        this is not the case for the current setting of
 217        `core.autocrlf`, git will reject the file.  The variable can
 218        be set to "warn", in which case git will only warn about an
 219        irreversible conversion but continue the operation.
 220+
 221CRLF conversion bears a slight chance of corrupting data.
 222autocrlf=true will convert CRLF to LF during commit and LF to
 223CRLF during checkout.  A file that contains a mixture of LF and
 224CRLF before the commit cannot be recreated by git.  For text
 225files this is the right thing to do: it corrects line endings
 226such that we have only LF line endings in the repository.
 227But for binary files that are accidentally classified as text the
 228conversion can corrupt data.
 229+
 230If you recognize such corruption early you can easily fix it by
 231setting the conversion type explicitly in .gitattributes.  Right
 232after committing you still have the original file in your work
 233tree and this file is not yet corrupted.  You can explicitly tell
 234git that this file is binary and git will handle the file
 235appropriately.
 236+
 237Unfortunately, the desired effect of cleaning up text files with
 238mixed line endings and the undesired effect of corrupting binary
 239files cannot be distinguished.  In both cases CRLFs are removed
 240in an irreversible way.  For text files this is the right thing
 241to do because CRLFs are line endings, while for binary files
 242converting CRLFs corrupts data.
 243+
 244Note, this safety check does not mean that a checkout will generate a
 245file identical to the original file for a different setting of
 246`core.autocrlf`, but only for the current one.  For example, a text
 247file with `LF` would be accepted with `core.autocrlf=input` and could
 248later be checked out with `core.autocrlf=true`, in which case the
 249resulting file would contain `CRLF`, although the original file
 250contained `LF`.  However, in both work trees the line endings would be
 251consistent, that is either all `LF` or all `CRLF`, but never mixed.  A
 252file with mixed line endings would be reported by the `core.safecrlf`
 253mechanism.
 254
 255core.symlinks::
 256        If false, symbolic links are checked out as small plain files that
 257        contain the link text. linkgit:git-update-index[1] and
 258        linkgit:git-add[1] will not change the recorded type to regular
 259        file. Useful on filesystems like FAT that do not support
 260        symbolic links.
 261+
 262The default is true, except linkgit:git-clone[1] or linkgit:git-init[1]
 263will probe and set core.symlinks false if appropriate when the repository
 264is created.
 265
 266core.gitProxy::
 267        A "proxy command" to execute (as 'command host port') instead
 268        of establishing direct connection to the remote server when
 269        using the git protocol for fetching. If the variable value is
 270        in the "COMMAND for DOMAIN" format, the command is applied only
 271        on hostnames ending with the specified domain string. This variable
 272        may be set multiple times and is matched in the given order;
 273        the first match wins.
 274+
 275Can be overridden by the 'GIT_PROXY_COMMAND' environment variable
 276(which always applies universally, without the special "for"
 277handling).
 278+
 279The special string `none` can be used as the proxy command to
 280specify that no proxy be used for a given domain pattern.
 281This is useful for excluding servers inside a firewall from
 282proxy use, while defaulting to a common proxy for external domains.
 283
 284core.ignoreStat::
 285        If true, commands which modify both the working tree and the index
 286        will mark the updated paths with the "assume unchanged" bit in the
 287        index. These marked files are then assumed to stay unchanged in the
 288        working copy, until you mark them otherwise manually - Git will not
 289        detect the file changes by lstat() calls. This is useful on systems
 290        where those are very slow, such as Microsoft Windows.
 291        See linkgit:git-update-index[1].
 292        False by default.
 293
 294core.preferSymlinkRefs::
 295        Instead of the default "symref" format for HEAD
 296        and other symbolic reference files, use symbolic links.
 297        This is sometimes needed to work with old scripts that
 298        expect HEAD to be a symbolic link.
 299
 300core.bare::
 301        If true this repository is assumed to be 'bare' and has no
 302        working directory associated with it.  If this is the case a
 303        number of commands that require a working directory will be
 304        disabled, such as linkgit:git-add[1] or linkgit:git-merge[1].
 305+
 306This setting is automatically guessed by linkgit:git-clone[1] or
 307linkgit:git-init[1] when the repository was created.  By default a
 308repository that ends in "/.git" is assumed to be not bare (bare =
 309false), while all other repositories are assumed to be bare (bare
 310= true).
 311
 312core.worktree::
 313        Set the path to the root of the work tree.
 314        This can be overridden by the GIT_WORK_TREE environment
 315        variable and the '--work-tree' command line option. It can be
 316        an absolute path or a relative path to the .git directory,
 317        either specified by --git-dir or GIT_DIR, or automatically
 318        discovered.
 319        If --git-dir or GIT_DIR are specified but none of
 320        --work-tree, GIT_WORK_TREE and core.worktree is specified,
 321        the current working directory is regarded as the root of the
 322        work tree.
 323+
 324Note that this variable is honored even when set in a configuration
 325file in a ".git" subdirectory of a directory, and its value differs
 326from the latter directory (e.g. "/path/to/.git/config" has
 327core.worktree set to "/different/path"), which is most likely a
 328misconfiguration.  Running git commands in "/path/to" directory will
 329still use "/different/path" as the root of the work tree and can cause
 330great confusion to the users.
 331
 332core.logAllRefUpdates::
 333        Enable the reflog. Updates to a ref <ref> is logged to the file
 334        "$GIT_DIR/logs/<ref>", by appending the new and old
 335        SHA1, the date/time and the reason of the update, but
 336        only when the file exists.  If this configuration
 337        variable is set to true, missing "$GIT_DIR/logs/<ref>"
 338        file is automatically created for branch heads.
 339+
 340This information can be used to determine what commit
 341was the tip of a branch "2 days ago".
 342+
 343This value is true by default in a repository that has
 344a working directory associated with it, and false by
 345default in a bare repository.
 346
 347core.repositoryFormatVersion::
 348        Internal variable identifying the repository format and layout
 349        version.
 350
 351core.sharedRepository::
 352        When 'group' (or 'true'), the repository is made shareable between
 353        several users in a group (making sure all the files and objects are
 354        group-writable). When 'all' (or 'world' or 'everybody'), the
 355        repository will be readable by all users, additionally to being
 356        group-shareable. When 'umask' (or 'false'), git will use permissions
 357        reported by umask(2). When '0xxx', where '0xxx' is an octal number,
 358        files in the repository will have this mode value. '0xxx' will override
 359        user's umask value (whereas the other options will only override
 360        requested parts of the user's umask value). Examples: '0660' will make
 361        the repo read/write-able for the owner and group, but inaccessible to
 362        others (equivalent to 'group' unless umask is e.g. '0022'). '0640' is a
 363        repository that is group-readable but not group-writable.
 364        See linkgit:git-init[1]. False by default.
 365
 366core.warnAmbiguousRefs::
 367        If true, git will warn you if the ref name you passed it is ambiguous
 368        and might match multiple refs in the .git/refs/ tree. True by default.
 369
 370core.compression::
 371        An integer -1..9, indicating a default compression level.
 372        -1 is the zlib default. 0 means no compression,
 373        and 1..9 are various speed/size tradeoffs, 9 being slowest.
 374        If set, this provides a default to other compression variables,
 375        such as 'core.loosecompression' and 'pack.compression'.
 376
 377core.loosecompression::
 378        An integer -1..9, indicating the compression level for objects that
 379        are not in a pack file. -1 is the zlib default. 0 means no
 380        compression, and 1..9 are various speed/size tradeoffs, 9 being
 381        slowest.  If not set,  defaults to core.compression.  If that is
 382        not set,  defaults to 1 (best speed).
 383
 384core.packedGitWindowSize::
 385        Number of bytes of a pack file to map into memory in a
 386        single mapping operation.  Larger window sizes may allow
 387        your system to process a smaller number of large pack files
 388        more quickly.  Smaller window sizes will negatively affect
 389        performance due to increased calls to the operating system's
 390        memory manager, but may improve performance when accessing
 391        a large number of large pack files.
 392+
 393Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
 394MiB on 32 bit platforms and 1 GiB on 64 bit platforms.  This should
 395be reasonable for all users/operating systems.  You probably do
 396not need to adjust this value.
 397+
 398Common unit suffixes of 'k', 'm', or 'g' are supported.
 399
 400core.packedGitLimit::
 401        Maximum number of bytes to map simultaneously into memory
 402        from pack files.  If Git needs to access more than this many
 403        bytes at once to complete an operation it will unmap existing
 404        regions to reclaim virtual address space within the process.
 405+
 406Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms.
 407This should be reasonable for all users/operating systems, except on
 408the largest projects.  You probably do not need to adjust this value.
 409+
 410Common unit suffixes of 'k', 'm', or 'g' are supported.
 411
 412core.deltaBaseCacheLimit::
 413        Maximum number of bytes to reserve for caching base objects
 414        that multiple deltafied objects reference.  By storing the
 415        entire decompressed base objects in a cache Git is able
 416        to avoid unpacking and decompressing frequently used base
 417        objects multiple times.
 418+
 419Default is 16 MiB on all platforms.  This should be reasonable
 420for all users/operating systems, except on the largest projects.
 421You probably do not need to adjust this value.
 422+
 423Common unit suffixes of 'k', 'm', or 'g' are supported.
 424
 425core.bigFileThreshold::
 426        Files larger than this size are stored deflated, without
 427        attempting delta compression.  Storing large files without
 428        delta compression avoids excessive memory usage, at the
 429        slight expense of increased disk usage.
 430+
 431Default is 512 MiB on all platforms.  This should be reasonable
 432for most projects as source code and other text files can still
 433be delta compressed, but larger binary media files won't be.
 434+
 435Common unit suffixes of 'k', 'm', or 'g' are supported.
 436+
 437Currently only linkgit:git-fast-import[1] honors this setting.
 438
 439core.excludesfile::
 440        In addition to '.gitignore' (per-directory) and
 441        '.git/info/exclude', git looks into this file for patterns
 442        of files which are not meant to be tracked.  "{tilde}/" is expanded
 443        to the value of `$HOME` and "{tilde}user/" to the specified user's
 444        home directory.  See linkgit:gitignore[5].
 445
 446core.editor::
 447        Commands such as `commit` and `tag` that lets you edit
 448        messages by launching an editor uses the value of this
 449        variable when it is set, and the environment variable
 450        `GIT_EDITOR` is not set.  See linkgit:git-var[1].
 451
 452core.pager::
 453        The command that git will use to paginate output.  Can
 454        be overridden with the `GIT_PAGER` environment
 455        variable.  Note that git sets the `LESS` environment
 456        variable to `FRSX` if it is unset when it runs the
 457        pager.  One can change these settings by setting the
 458        `LESS` variable to some other value.  Alternately,
 459        these settings can be overridden on a project or
 460        global basis by setting the `core.pager` option.
 461        Setting `core.pager` has no affect on the `LESS`
 462        environment variable behaviour above, so if you want
 463        to override git's default settings this way, you need
 464        to be explicit.  For example, to disable the S option
 465        in a backward compatible manner, set `core.pager`
 466        to `less -+$LESS -FRX`.  This will be passed to the
 467        shell by git, which will translate the final command to
 468        `LESS=FRSX less -+FRSX -FRX`.
 469
 470core.whitespace::
 471        A comma separated list of common whitespace problems to
 472        notice.  'git diff' will use `color.diff.whitespace` to
 473        highlight them, and 'git apply --whitespace=error' will
 474        consider them as errors.  You can prefix `-` to disable
 475        any of them (e.g. `-trailing-space`):
 476+
 477* `blank-at-eol` treats trailing whitespaces at the end of the line
 478  as an error (enabled by default).
 479* `space-before-tab` treats a space character that appears immediately
 480  before a tab character in the initial indent part of the line as an
 481  error (enabled by default).
 482* `indent-with-non-tab` treats a line that is indented with 8 or more
 483  space characters as an error (not enabled by default).
 484* `tab-in-indent` treats a tab character in the initial indent part of
 485  the line as an error (not enabled by default).
 486* `blank-at-eof` treats blank lines added at the end of file as an error
 487  (enabled by default).
 488* `trailing-space` is a short-hand to cover both `blank-at-eol` and
 489  `blank-at-eof`.
 490* `cr-at-eol` treats a carriage-return at the end of line as
 491  part of the line terminator, i.e. with it, `trailing-space`
 492  does not trigger if the character before such a carriage-return
 493  is not a whitespace (not enabled by default).
 494
 495core.fsyncobjectfiles::
 496        This boolean will enable 'fsync()' when writing object files.
 497+
 498This is a total waste of time and effort on a filesystem that orders
 499data writes properly, but can be useful for filesystems that do not use
 500journalling (traditional UNIX filesystems) or that only journal metadata
 501and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback").
 502
 503core.preloadindex::
 504        Enable parallel index preload for operations like 'git diff'
 505+
 506This can speed up operations like 'git diff' and 'git status' especially
 507on filesystems like NFS that have weak caching semantics and thus
 508relatively high IO latencies.  With this set to 'true', git will do the
 509index comparison to the filesystem data in parallel, allowing
 510overlapping IO's.
 511
 512core.createObject::
 513        You can set this to 'link', in which case a hardlink followed by
 514        a delete of the source are used to make sure that object creation
 515        will not overwrite existing objects.
 516+
 517On some file system/operating system combinations, this is unreliable.
 518Set this config setting to 'rename' there; However, This will remove the
 519check that makes sure that existing object files will not get overwritten.
 520
 521core.notesRef::
 522        When showing commit messages, also show notes which are stored in
 523        the given ref.  The ref must be fully qualified.  If the given
 524        ref does not exist, it is not an error but means that no
 525        notes should be printed.
 526+
 527This setting defaults to "refs/notes/commits", and it can be overridden by
 528the 'GIT_NOTES_REF' environment variable.  See linkgit:git-notes[1].
 529
 530core.sparseCheckout::
 531        Enable "sparse checkout" feature. See section "Sparse checkout" in
 532        linkgit:git-read-tree[1] for more information.
 533
 534add.ignore-errors::
 535        Tells 'git add' to continue adding files when some files cannot be
 536        added due to indexing errors. Equivalent to the '--ignore-errors'
 537        option of linkgit:git-add[1].
 538
 539alias.*::
 540        Command aliases for the linkgit:git[1] command wrapper - e.g.
 541        after defining "alias.last = cat-file commit HEAD", the invocation
 542        "git last" is equivalent to "git cat-file commit HEAD". To avoid
 543        confusion and troubles with script usage, aliases that
 544        hide existing git commands are ignored. Arguments are split by
 545        spaces, the usual shell quoting and escaping is supported.
 546        quote pair and a backslash can be used to quote them.
 547+
 548If the alias expansion is prefixed with an exclamation point,
 549it will be treated as a shell command.  For example, defining
 550"alias.new = !gitk --all --not ORIG_HEAD", the invocation
 551"git new" is equivalent to running the shell command
 552"gitk --all --not ORIG_HEAD".  Note that shell commands will be
 553executed from the top-level directory of a repository, which may
 554not necessarily be the current directory.
 555
 556am.keepcr::
 557        If true, git-am will call git-mailsplit for patches in mbox format
 558        with parameter '--keep-cr'. In this case git-mailsplit will
 559        not remove `\r` from lines ending with `\r\n`. Can be overrriden
 560        by giving '--no-keep-cr' from the command line.
 561        See linkgit:git-am[1], linkgit:git-mailsplit[1].
 562
 563apply.ignorewhitespace::
 564        When set to 'change', tells 'git apply' to ignore changes in
 565        whitespace, in the same way as the '--ignore-space-change'
 566        option.
 567        When set to one of: no, none, never, false tells 'git apply' to
 568        respect all whitespace differences.
 569        See linkgit:git-apply[1].
 570
 571apply.whitespace::
 572        Tells 'git apply' how to handle whitespaces, in the same way
 573        as the '--whitespace' option. See linkgit:git-apply[1].
 574
 575branch.autosetupmerge::
 576        Tells 'git branch' and 'git checkout' to set up new branches
 577        so that linkgit:git-pull[1] will appropriately merge from the
 578        starting point branch. Note that even if this option is not set,
 579        this behavior can be chosen per-branch using the `--track`
 580        and `--no-track` options. The valid settings are: `false` -- no
 581        automatic setup is done; `true` -- automatic setup is done when the
 582        starting point is a remote branch; `always` -- automatic setup is
 583        done when the starting point is either a local branch or remote
 584        branch. This option defaults to true.
 585
 586branch.autosetuprebase::
 587        When a new branch is created with 'git branch' or 'git checkout'
 588        that tracks another branch, this variable tells git to set
 589        up pull to rebase instead of merge (see "branch.<name>.rebase").
 590        When `never`, rebase is never automatically set to true.
 591        When `local`, rebase is set to true for tracked branches of
 592        other local branches.
 593        When `remote`, rebase is set to true for tracked branches of
 594        remote branches.
 595        When `always`, rebase will be set to true for all tracking
 596        branches.
 597        See "branch.autosetupmerge" for details on how to set up a
 598        branch to track another branch.
 599        This option defaults to never.
 600
 601branch.<name>.remote::
 602        When in branch <name>, it tells 'git fetch' and 'git push' which
 603        remote to fetch from/push to.  It defaults to `origin` if no remote is
 604        configured. `origin` is also used if you are not on any branch.
 605
 606branch.<name>.merge::
 607        Defines, together with branch.<name>.remote, the upstream branch
 608        for the given branch. It tells 'git fetch'/'git pull' which
 609        branch to merge and can also affect 'git push' (see push.default).
 610        When in branch <name>, it tells 'git fetch' the default
 611        refspec to be marked for merging in FETCH_HEAD. The value is
 612        handled like the remote part of a refspec, and must match a
 613        ref which is fetched from the remote given by
 614        "branch.<name>.remote".
 615        The merge information is used by 'git pull' (which at first calls
 616        'git fetch') to lookup the default branch for merging. Without
 617        this option, 'git pull' defaults to merge the first refspec fetched.
 618        Specify multiple values to get an octopus merge.
 619        If you wish to setup 'git pull' so that it merges into <name> from
 620        another branch in the local repository, you can point
 621        branch.<name>.merge to the desired branch, and use the special setting
 622        `.` (a period) for branch.<name>.remote.
 623
 624branch.<name>.mergeoptions::
 625        Sets default options for merging into branch <name>. The syntax and
 626        supported options are the same as those of linkgit:git-merge[1], but
 627        option values containing whitespace characters are currently not
 628        supported.
 629
 630branch.<name>.rebase::
 631        When true, rebase the branch <name> on top of the fetched branch,
 632        instead of merging the default branch from the default remote when
 633        "git pull" is run.
 634        *NOTE*: this is a possibly dangerous operation; do *not* use
 635        it unless you understand the implications (see linkgit:git-rebase[1]
 636        for details).
 637
 638browser.<tool>.cmd::
 639        Specify the command to invoke the specified browser. The
 640        specified command is evaluated in shell with the URLs passed
 641        as arguments. (See linkgit:git-web--browse[1].)
 642
 643browser.<tool>.path::
 644        Override the path for the given tool that may be used to
 645        browse HTML help (see '-w' option in linkgit:git-help[1]) or a
 646        working repository in gitweb (see linkgit:git-instaweb[1]).
 647
 648clean.requireForce::
 649        A boolean to make git-clean do nothing unless given -f
 650        or -n.   Defaults to true.
 651
 652color.branch::
 653        A boolean to enable/disable color in the output of
 654        linkgit:git-branch[1]. May be set to `always`,
 655        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 656        only when the output is to a terminal. Defaults to false.
 657
 658color.branch.<slot>::
 659        Use customized color for branch coloration. `<slot>` is one of
 660        `current` (the current branch), `local` (a local branch),
 661        `remote` (a tracking branch in refs/remotes/), `plain` (other
 662        refs).
 663+
 664The value for these configuration variables is a list of colors (at most
 665two) and attributes (at most one), separated by spaces.  The colors
 666accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`,
 667`magenta`, `cyan` and `white`; the attributes are `bold`, `dim`, `ul`,
 668`blink` and `reverse`.  The first color given is the foreground; the
 669second is the background.  The position of the attribute, if any,
 670doesn't matter.
 671
 672color.diff::
 673        When set to `always`, always use colors in patch.
 674        When false (or `never`), never.  When set to `true` or `auto`, use
 675        colors only when the output is to the terminal. Defaults to false.
 676
 677color.diff.<slot>::
 678        Use customized color for diff colorization.  `<slot>` specifies
 679        which part of the patch to use the specified color, and is one
 680        of `plain` (context text), `meta` (metainformation), `frag`
 681        (hunk header), 'func' (function in hunk header), `old` (removed lines),
 682        `new` (added lines), `commit` (commit headers), or `whitespace`
 683        (highlighting whitespace errors). The values of these variables may be
 684        specified as in color.branch.<slot>.
 685
 686color.grep::
 687        When set to `always`, always highlight matches.  When `false` (or
 688        `never`), never.  When set to `true` or `auto`, use color only
 689        when the output is written to the terminal.  Defaults to `false`.
 690
 691color.grep.<slot>::
 692        Use customized color for grep colorization.  `<slot>` specifies which
 693        part of the line to use the specified color, and is one of
 694+
 695--
 696`context`;;
 697        non-matching text in context lines (when using `-A`, `-B`, or `-C`)
 698`filename`;;
 699        filename prefix (when not using `-h`)
 700`function`;;
 701        function name lines (when using `-p`)
 702`linenumber`;;
 703        line number prefix (when using `-n`)
 704`match`;;
 705        matching text
 706`selected`;;
 707        non-matching text in selected lines
 708`separator`;;
 709        separators between fields on a line (`:`, `-`, and `=`)
 710        and between hunks (`--`)
 711--
 712+
 713The values of these variables may be specified as in color.branch.<slot>.
 714
 715color.interactive::
 716        When set to `always`, always use colors for interactive prompts
 717        and displays (such as those used by "git-add --interactive").
 718        When false (or `never`), never.  When set to `true` or `auto`, use
 719        colors only when the output is to the terminal. Defaults to false.
 720
 721color.interactive.<slot>::
 722        Use customized color for 'git add --interactive'
 723        output. `<slot>` may be `prompt`, `header`, `help` or `error`, for
 724        four distinct types of normal output from interactive
 725        commands.  The values of these variables may be specified as
 726        in color.branch.<slot>.
 727
 728color.pager::
 729        A boolean to enable/disable colored output when the pager is in
 730        use (default is true).
 731
 732color.showbranch::
 733        A boolean to enable/disable color in the output of
 734        linkgit:git-show-branch[1]. May be set to `always`,
 735        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 736        only when the output is to a terminal. Defaults to false.
 737
 738color.status::
 739        A boolean to enable/disable color in the output of
 740        linkgit:git-status[1]. May be set to `always`,
 741        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 742        only when the output is to a terminal. Defaults to false.
 743
 744color.status.<slot>::
 745        Use customized color for status colorization. `<slot>` is
 746        one of `header` (the header text of the status message),
 747        `added` or `updated` (files which are added but not committed),
 748        `changed` (files which are changed but not added in the index),
 749        `untracked` (files which are not tracked by git), or
 750        `nobranch` (the color the 'no branch' warning is shown in, defaulting
 751        to red). The values of these variables may be specified as in
 752        color.branch.<slot>.
 753
 754color.ui::
 755        When set to `always`, always use colors in all git commands which
 756        are capable of colored output. When false (or `never`), never. When
 757        set to `true` or `auto`, use colors only when the output is to the
 758        terminal. When more specific variables of color.* are set, they always
 759        take precedence over this setting. Defaults to false.
 760
 761commit.status::
 762        A boolean to enable/disable inclusion of status information in the
 763        commit message template when using an editor to prepare the commit
 764        message.  Defaults to true.
 765
 766commit.template::
 767        Specify a file to use as the template for new commit messages.
 768        "{tilde}/" is expanded to the value of `$HOME` and "{tilde}user/" to the
 769        specified user's home directory.
 770
 771diff.autorefreshindex::
 772        When using 'git diff' to compare with work tree
 773        files, do not consider stat-only change as changed.
 774        Instead, silently run `git update-index --refresh` to
 775        update the cached stat information for paths whose
 776        contents in the work tree match the contents in the
 777        index.  This option defaults to true.  Note that this
 778        affects only 'git diff' Porcelain, and not lower level
 779        'diff' commands such as 'git diff-files'.
 780
 781diff.external::
 782        If this config variable is set, diff generation is not
 783        performed using the internal diff machinery, but using the
 784        given command.  Can be overridden with the `GIT_EXTERNAL_DIFF'
 785        environment variable.  The command is called with parameters
 786        as described under "git Diffs" in linkgit:git[1].  Note: if
 787        you want to use an external diff program only on a subset of
 788        your files, you might want to use linkgit:gitattributes[5] instead.
 789
 790diff.mnemonicprefix::
 791        If set, 'git diff' uses a prefix pair that is different from the
 792        standard "a/" and "b/" depending on what is being compared.  When
 793        this configuration is in effect, reverse diff output also swaps
 794        the order of the prefixes:
 795diff.noprefix::
 796        If set, 'git diff' does not show any source or destination prefix.
 797`git diff`;;
 798        compares the (i)ndex and the (w)ork tree;
 799`git diff HEAD`;;
 800         compares a (c)ommit and the (w)ork tree;
 801`git diff --cached`;;
 802        compares a (c)ommit and the (i)ndex;
 803`git diff HEAD:file1 file2`;;
 804        compares an (o)bject and a (w)ork tree entity;
 805`git diff --no-index a b`;;
 806        compares two non-git things (1) and (2).
 807
 808diff.renameLimit::
 809        The number of files to consider when performing the copy/rename
 810        detection; equivalent to the 'git diff' option '-l'.
 811
 812diff.renames::
 813        Tells git to detect renames.  If set to any boolean value, it
 814        will enable basic rename detection.  If set to "copies" or
 815        "copy", it will detect copies, as well.
 816
 817diff.suppressBlankEmpty::
 818        A boolean to inhibit the standard behavior of printing a space
 819        before each empty output line. Defaults to false.
 820
 821diff.tool::
 822        Controls which diff tool is used.  `diff.tool` overrides
 823        `merge.tool` when used by linkgit:git-difftool[1] and has
 824        the same valid values as `merge.tool` minus "tortoisemerge"
 825        and plus "kompare".
 826
 827difftool.<tool>.path::
 828        Override the path for the given tool.  This is useful in case
 829        your tool is not in the PATH.
 830
 831difftool.<tool>.cmd::
 832        Specify the command to invoke the specified diff tool.
 833        The specified command is evaluated in shell with the following
 834        variables available:  'LOCAL' is set to the name of the temporary
 835        file containing the contents of the diff pre-image and 'REMOTE'
 836        is set to the name of the temporary file containing the contents
 837        of the diff post-image.
 838
 839difftool.prompt::
 840        Prompt before each invocation of the diff tool.
 841
 842diff.wordRegex::
 843        A POSIX Extended Regular Expression used to determine what is a "word"
 844        when performing word-by-word difference calculations.  Character
 845        sequences that match the regular expression are "words", all other
 846        characters are *ignorable* whitespace.
 847
 848fetch.unpackLimit::
 849        If the number of objects fetched over the git native
 850        transfer is below this
 851        limit, then the objects will be unpacked into loose object
 852        files. However if the number of received objects equals or
 853        exceeds this limit then the received pack will be stored as
 854        a pack, after adding any missing delta bases.  Storing the
 855        pack from a push can make the push operation complete faster,
 856        especially on slow filesystems.  If not set, the value of
 857        `transfer.unpackLimit` is used instead.
 858
 859format.attach::
 860        Enable multipart/mixed attachments as the default for
 861        'format-patch'.  The value can also be a double quoted string
 862        which will enable attachments as the default and set the
 863        value as the boundary.  See the --attach option in
 864        linkgit:git-format-patch[1].
 865
 866format.numbered::
 867        A boolean which can enable or disable sequence numbers in patch
 868        subjects.  It defaults to "auto" which enables it only if there
 869        is more than one patch.  It can be enabled or disabled for all
 870        messages by setting it to "true" or "false".  See --numbered
 871        option in linkgit:git-format-patch[1].
 872
 873format.headers::
 874        Additional email headers to include in a patch to be submitted
 875        by mail.  See linkgit:git-format-patch[1].
 876
 877format.cc::
 878        Additional "Cc:" headers to include in a patch to be submitted
 879        by mail.  See the --cc option in linkgit:git-format-patch[1].
 880
 881format.subjectprefix::
 882        The default for format-patch is to output files with the '[PATCH]'
 883        subject prefix. Use this variable to change that prefix.
 884
 885format.suffix::
 886        The default for format-patch is to output files with the suffix
 887        `.patch`. Use this variable to change that suffix (make sure to
 888        include the dot if you want it).
 889
 890format.pretty::
 891        The default pretty format for log/show/whatchanged command,
 892        See linkgit:git-log[1], linkgit:git-show[1],
 893        linkgit:git-whatchanged[1].
 894
 895format.thread::
 896        The default threading style for 'git format-patch'.  Can be
 897        a boolean value, or `shallow` or `deep`.  `shallow` threading
 898        makes every mail a reply to the head of the series,
 899        where the head is chosen from the cover letter, the
 900        `\--in-reply-to`, and the first patch mail, in this order.
 901        `deep` threading makes every mail a reply to the previous one.
 902        A true boolean value is the same as `shallow`, and a false
 903        value disables threading.
 904
 905format.signoff::
 906    A boolean value which lets you enable the `-s/--signoff` option of
 907    format-patch by default. *Note:* Adding the Signed-off-by: line to a
 908    patch should be a conscious act and means that you certify you have
 909    the rights to submit this work under the same open source license.
 910    Please see the 'SubmittingPatches' document for further discussion.
 911
 912gc.aggressiveWindow::
 913        The window size parameter used in the delta compression
 914        algorithm used by 'git gc --aggressive'.  This defaults
 915        to 250.
 916
 917gc.auto::
 918        When there are approximately more than this many loose
 919        objects in the repository, `git gc --auto` will pack them.
 920        Some Porcelain commands use this command to perform a
 921        light-weight garbage collection from time to time.  The
 922        default value is 6700.  Setting this to 0 disables it.
 923
 924gc.autopacklimit::
 925        When there are more than this many packs that are not
 926        marked with `*.keep` file in the repository, `git gc
 927        --auto` consolidates them into one larger pack.  The
 928        default value is 50.  Setting this to 0 disables it.
 929
 930gc.packrefs::
 931        Running `git pack-refs` in a repository renders it
 932        unclonable by Git versions prior to 1.5.1.2 over dumb
 933        transports such as HTTP.  This variable determines whether
 934        'git gc' runs `git pack-refs`. This can be set to `nobare`
 935        to enable it within all non-bare repos or it can be set to a
 936        boolean value.  The default is `true`.
 937
 938gc.pruneexpire::
 939        When 'git gc' is run, it will call 'prune --expire 2.weeks.ago'.
 940        Override the grace period with this config variable.  The value
 941        "now" may be used to disable this  grace period and always prune
 942        unreachable objects immediately.
 943
 944gc.reflogexpire::
 945gc.<pattern>.reflogexpire::
 946        'git reflog expire' removes reflog entries older than
 947        this time; defaults to 90 days.  With "<pattern>" (e.g.
 948        "refs/stash") in the middle the setting applies only to
 949        the refs that match the <pattern>.
 950
 951gc.reflogexpireunreachable::
 952gc.<ref>.reflogexpireunreachable::
 953        'git reflog expire' removes reflog entries older than
 954        this time and are not reachable from the current tip;
 955        defaults to 30 days.  With "<pattern>" (e.g. "refs/stash")
 956        in the middle, the setting applies only to the refs that
 957        match the <pattern>.
 958
 959gc.rerereresolved::
 960        Records of conflicted merge you resolved earlier are
 961        kept for this many days when 'git rerere gc' is run.
 962        The default is 60 days.  See linkgit:git-rerere[1].
 963
 964gc.rerereunresolved::
 965        Records of conflicted merge you have not resolved are
 966        kept for this many days when 'git rerere gc' is run.
 967        The default is 15 days.  See linkgit:git-rerere[1].
 968
 969gitcvs.commitmsgannotation::
 970        Append this string to each commit message. Set to empty string
 971        to disable this feature. Defaults to "via git-CVS emulator".
 972
 973gitcvs.enabled::
 974        Whether the CVS server interface is enabled for this repository.
 975        See linkgit:git-cvsserver[1].
 976
 977gitcvs.logfile::
 978        Path to a log file where the CVS server interface well... logs
 979        various stuff. See linkgit:git-cvsserver[1].
 980
 981gitcvs.usecrlfattr::
 982        If true, the server will look up the `crlf` attribute for
 983        files to determine the '-k' modes to use. If `crlf` is set,
 984        the '-k' mode will be left blank, so cvs clients will
 985        treat it as text. If `crlf` is explicitly unset, the file
 986        will be set with '-kb' mode, which suppresses any newline munging
 987        the client might otherwise do. If `crlf` is not specified,
 988        then 'gitcvs.allbinary' is used. See linkgit:gitattributes[5].
 989
 990gitcvs.allbinary::
 991        This is used if 'gitcvs.usecrlfattr' does not resolve
 992        the correct '-kb' mode to use. If true, all
 993        unresolved files are sent to the client in
 994        mode '-kb'. This causes the client to treat them
 995        as binary files, which suppresses any newline munging it
 996        otherwise might do. Alternatively, if it is set to "guess",
 997        then the contents of the file are examined to decide if
 998        it is binary, similar to 'core.autocrlf'.
 999
1000gitcvs.dbname::
1001        Database used by git-cvsserver to cache revision information
1002        derived from the git repository. The exact meaning depends on the
1003        used database driver, for SQLite (which is the default driver) this
1004        is a filename. Supports variable substitution (see
1005        linkgit:git-cvsserver[1] for details). May not contain semicolons (`;`).
1006        Default: '%Ggitcvs.%m.sqlite'
1007
1008gitcvs.dbdriver::
1009        Used Perl DBI driver. You can specify any available driver
1010        for this here, but it might not work. git-cvsserver is tested
1011        with 'DBD::SQLite', reported to work with 'DBD::Pg', and
1012        reported *not* to work with 'DBD::mysql'. Experimental feature.
1013        May not contain double colons (`:`). Default: 'SQLite'.
1014        See linkgit:git-cvsserver[1].
1015
1016gitcvs.dbuser, gitcvs.dbpass::
1017        Database user and password. Only useful if setting 'gitcvs.dbdriver',
1018        since SQLite has no concept of database users and/or passwords.
1019        'gitcvs.dbuser' supports variable substitution (see
1020        linkgit:git-cvsserver[1] for details).
1021
1022gitcvs.dbTableNamePrefix::
1023        Database table name prefix.  Prepended to the names of any
1024        database tables used, allowing a single database to be used
1025        for several repositories.  Supports variable substitution (see
1026        linkgit:git-cvsserver[1] for details).  Any non-alphabetic
1027        characters will be replaced with underscores.
1028
1029All gitcvs variables except for 'gitcvs.usecrlfattr' and
1030'gitcvs.allbinary' can also be specified as
1031'gitcvs.<access_method>.<varname>' (where 'access_method'
1032is one of "ext" and "pserver") to make them apply only for the given
1033access method.
1034
1035gui.commitmsgwidth::
1036        Defines how wide the commit message window is in the
1037        linkgit:git-gui[1]. "75" is the default.
1038
1039gui.diffcontext::
1040        Specifies how many context lines should be used in calls to diff
1041        made by the linkgit:git-gui[1]. The default is "5".
1042
1043gui.encoding::
1044        Specifies the default encoding to use for displaying of
1045        file contents in linkgit:git-gui[1] and linkgit:gitk[1].
1046        It can be overridden by setting the 'encoding' attribute
1047        for relevant files (see linkgit:gitattributes[5]).
1048        If this option is not set, the tools default to the
1049        locale encoding.
1050
1051gui.matchtrackingbranch::
1052        Determines if new branches created with linkgit:git-gui[1] should
1053        default to tracking remote branches with matching names or
1054        not. Default: "false".
1055
1056gui.newbranchtemplate::
1057        Is used as suggested name when creating new branches using the
1058        linkgit:git-gui[1].
1059
1060gui.pruneduringfetch::
1061        "true" if linkgit:git-gui[1] should prune tracking branches when
1062        performing a fetch. The default value is "false".
1063
1064gui.trustmtime::
1065        Determines if linkgit:git-gui[1] should trust the file modification
1066        timestamp or not. By default the timestamps are not trusted.
1067
1068gui.spellingdictionary::
1069        Specifies the dictionary used for spell checking commit messages in
1070        the linkgit:git-gui[1]. When set to "none" spell checking is turned
1071        off.
1072
1073gui.fastcopyblame::
1074        If true, 'git gui blame' uses `-C` instead of `-C -C` for original
1075        location detection. It makes blame significantly faster on huge
1076        repositories at the expense of less thorough copy detection.
1077
1078gui.copyblamethreshold::
1079        Specifies the threshold to use in 'git gui blame' original location
1080        detection, measured in alphanumeric characters. See the
1081        linkgit:git-blame[1] manual for more information on copy detection.
1082
1083gui.blamehistoryctx::
1084        Specifies the radius of history context in days to show in
1085        linkgit:gitk[1] for the selected commit, when the `Show History
1086        Context` menu item is invoked from 'git gui blame'. If this
1087        variable is set to zero, the whole history is shown.
1088
1089guitool.<name>.cmd::
1090        Specifies the shell command line to execute when the corresponding item
1091        of the linkgit:git-gui[1] `Tools` menu is invoked. This option is
1092        mandatory for every tool. The command is executed from the root of
1093        the working directory, and in the environment it receives the name of
1094        the tool as 'GIT_GUITOOL', the name of the currently selected file as
1095        'FILENAME', and the name of the current branch as 'CUR_BRANCH' (if
1096        the head is detached, 'CUR_BRANCH' is empty).
1097
1098guitool.<name>.needsfile::
1099        Run the tool only if a diff is selected in the GUI. It guarantees
1100        that 'FILENAME' is not empty.
1101
1102guitool.<name>.noconsole::
1103        Run the command silently, without creating a window to display its
1104        output.
1105
1106guitool.<name>.norescan::
1107        Don't rescan the working directory for changes after the tool
1108        finishes execution.
1109
1110guitool.<name>.confirm::
1111        Show a confirmation dialog before actually running the tool.
1112
1113guitool.<name>.argprompt::
1114        Request a string argument from the user, and pass it to the tool
1115        through the 'ARGS' environment variable. Since requesting an
1116        argument implies confirmation, the 'confirm' option has no effect
1117        if this is enabled. If the option is set to 'true', 'yes', or '1',
1118        the dialog uses a built-in generic prompt; otherwise the exact
1119        value of the variable is used.
1120
1121guitool.<name>.revprompt::
1122        Request a single valid revision from the user, and set the
1123        'REVISION' environment variable. In other aspects this option
1124        is similar to 'argprompt', and can be used together with it.
1125
1126guitool.<name>.revunmerged::
1127        Show only unmerged branches in the 'revprompt' subdialog.
1128        This is useful for tools similar to merge or rebase, but not
1129        for things like checkout or reset.
1130
1131guitool.<name>.title::
1132        Specifies the title to use for the prompt dialog. The default
1133        is the tool name.
1134
1135guitool.<name>.prompt::
1136        Specifies the general prompt string to display at the top of
1137        the dialog, before subsections for 'argprompt' and 'revprompt'.
1138        The default value includes the actual command.
1139
1140help.browser::
1141        Specify the browser that will be used to display help in the
1142        'web' format. See linkgit:git-help[1].
1143
1144help.format::
1145        Override the default help format used by linkgit:git-help[1].
1146        Values 'man', 'info', 'web' and 'html' are supported. 'man' is
1147        the default. 'web' and 'html' are the same.
1148
1149help.autocorrect::
1150        Automatically correct and execute mistyped commands after
1151        waiting for the given number of deciseconds (0.1 sec). If more
1152        than one command can be deduced from the entered text, nothing
1153        will be executed.  If the value of this option is negative,
1154        the corrected command will be executed immediately. If the
1155        value is 0 - the command will be just shown but not executed.
1156        This is the default.
1157
1158http.proxy::
1159        Override the HTTP proxy, normally configured using the 'http_proxy'
1160        environment variable (see linkgit:curl[1]).  This can be overridden
1161        on a per-remote basis; see remote.<name>.proxy
1162
1163http.sslVerify::
1164        Whether to verify the SSL certificate when fetching or pushing
1165        over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
1166        variable.
1167
1168http.sslCert::
1169        File containing the SSL certificate when fetching or pushing
1170        over HTTPS. Can be overridden by the 'GIT_SSL_CERT' environment
1171        variable.
1172
1173http.sslKey::
1174        File containing the SSL private key when fetching or pushing
1175        over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment
1176        variable.
1177
1178http.sslCertPasswordProtected::
1179        Enable git's password prompt for the SSL certificate.  Otherwise
1180        OpenSSL will prompt the user, possibly many times, if the
1181        certificate or private key is encrypted.  Can be overridden by the
1182        'GIT_SSL_CERT_PASSWORD_PROTECTED' environment variable.
1183
1184http.sslCAInfo::
1185        File containing the certificates to verify the peer with when
1186        fetching or pushing over HTTPS. Can be overridden by the
1187        'GIT_SSL_CAINFO' environment variable.
1188
1189http.sslCAPath::
1190        Path containing files with the CA certificates to verify the peer
1191        with when fetching or pushing over HTTPS. Can be overridden
1192        by the 'GIT_SSL_CAPATH' environment variable.
1193
1194http.maxRequests::
1195        How many HTTP requests to launch in parallel. Can be overridden
1196        by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5.
1197
1198http.minSessions::
1199        The number of curl sessions (counted across slots) to be kept across
1200        requests. They will not be ended with curl_easy_cleanup() until
1201        http_cleanup() is invoked. If USE_CURL_MULTI is not defined, this
1202        value will be capped at 1. Defaults to 1.
1203
1204http.postBuffer::
1205        Maximum size in bytes of the buffer used by smart HTTP
1206        transports when POSTing data to the remote system.
1207        For requests larger than this buffer size, HTTP/1.1 and
1208        Transfer-Encoding: chunked is used to avoid creating a
1209        massive pack file locally.  Default is 1 MiB, which is
1210        sufficient for most requests.
1211
1212http.lowSpeedLimit, http.lowSpeedTime::
1213        If the HTTP transfer speed is less than 'http.lowSpeedLimit'
1214        for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
1215        Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and
1216        'GIT_HTTP_LOW_SPEED_TIME' environment variables.
1217
1218http.noEPSV::
1219        A boolean which disables using of EPSV ftp command by curl.
1220        This can helpful with some "poor" ftp servers which don't
1221        support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
1222        environment variable. Default is false (curl will use EPSV).
1223
1224i18n.commitEncoding::
1225        Character encoding the commit messages are stored in; git itself
1226        does not care per se, but this information is necessary e.g. when
1227        importing commits from emails or in the gitk graphical history
1228        browser (and possibly at other places in the future or in other
1229        porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.
1230
1231i18n.logOutputEncoding::
1232        Character encoding the commit messages are converted to when
1233        running 'git log' and friends.
1234
1235imap::
1236        The configuration variables in the 'imap' section are described
1237        in linkgit:git-imap-send[1].
1238
1239init.templatedir::
1240        Specify the directory from which templates will be copied.
1241        (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].)
1242
1243instaweb.browser::
1244        Specify the program that will be used to browse your working
1245        repository in gitweb. See linkgit:git-instaweb[1].
1246
1247instaweb.httpd::
1248        The HTTP daemon command-line to start gitweb on your working
1249        repository. See linkgit:git-instaweb[1].
1250
1251instaweb.local::
1252        If true the web server started by linkgit:git-instaweb[1] will
1253        be bound to the local IP (127.0.0.1).
1254
1255instaweb.modulepath::
1256        The module path for an apache httpd used by linkgit:git-instaweb[1].
1257
1258instaweb.port::
1259        The port number to bind the gitweb httpd to. See
1260        linkgit:git-instaweb[1].
1261
1262interactive.singlekey::
1263        In interactive commands, allow the user to provide one-letter
1264        input with a single key (i.e., without hitting enter).
1265        Currently this is used only by the `\--patch` mode of
1266        linkgit:git-add[1].  Note that this setting is silently
1267        ignored if portable keystroke input is not available.
1268
1269log.date::
1270        Set default date-time mode for the log command. Setting log.date
1271        value is similar to using 'git log'\'s --date option. The value is one of the
1272        following alternatives: {relative,local,default,iso,rfc,short}.
1273        See linkgit:git-log[1].
1274
1275log.decorate::
1276        Print out the ref names of any commits that are shown by the log
1277        command. If 'short' is specified, the ref name prefixes 'refs/heads/',
1278        'refs/tags/' and 'refs/remotes/' will not be printed. If 'full' is
1279        specified, the full ref name (including prefix) will be printed.
1280        This is the same as the log commands '--decorate' option.
1281
1282log.showroot::
1283        If true, the initial commit will be shown as a big creation event.
1284        This is equivalent to a diff against an empty tree.
1285        Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
1286        normally hide the root commit will now show it. True by default.
1287
1288mailmap.file::
1289        The location of an augmenting mailmap file. The default
1290        mailmap, located in the root of the repository, is loaded
1291        first, then the mailmap file pointed to by this variable.
1292        The location of the mailmap file may be in a repository
1293        subdirectory, or somewhere outside of the repository itself.
1294        See linkgit:git-shortlog[1] and linkgit:git-blame[1].
1295
1296man.viewer::
1297        Specify the programs that may be used to display help in the
1298        'man' format. See linkgit:git-help[1].
1299
1300man.<tool>.cmd::
1301        Specify the command to invoke the specified man viewer. The
1302        specified command is evaluated in shell with the man page
1303        passed as argument. (See linkgit:git-help[1].)
1304
1305man.<tool>.path::
1306        Override the path for the given tool that may be used to
1307        display help in the 'man' format. See linkgit:git-help[1].
1308
1309include::merge-config.txt[]
1310
1311mergetool.<tool>.path::
1312        Override the path for the given tool.  This is useful in case
1313        your tool is not in the PATH.
1314
1315mergetool.<tool>.cmd::
1316        Specify the command to invoke the specified merge tool.  The
1317        specified command is evaluated in shell with the following
1318        variables available: 'BASE' is the name of a temporary file
1319        containing the common base of the files to be merged, if available;
1320        'LOCAL' is the name of a temporary file containing the contents of
1321        the file on the current branch; 'REMOTE' is the name of a temporary
1322        file containing the contents of the file from the branch being
1323        merged; 'MERGED' contains the name of the file to which the merge
1324        tool should write the results of a successful merge.
1325
1326mergetool.<tool>.trustExitCode::
1327        For a custom merge command, specify whether the exit code of
1328        the merge command can be used to determine whether the merge was
1329        successful.  If this is not set to true then the merge target file
1330        timestamp is checked and the merge assumed to have been successful
1331        if the file has been updated, otherwise the user is prompted to
1332        indicate the success of the merge.
1333
1334mergetool.keepBackup::
1335        After performing a merge, the original file with conflict markers
1336        can be saved as a file with a `.orig` extension.  If this variable
1337        is set to `false` then this file is not preserved.  Defaults to
1338        `true` (i.e. keep the backup files).
1339
1340mergetool.keepTemporaries::
1341        When invoking a custom merge tool, git uses a set of temporary
1342        files to pass to the tool. If the tool returns an error and this
1343        variable is set to `true`, then these temporary files will be
1344        preserved, otherwise they will be removed after the tool has
1345        exited. Defaults to `false`.
1346
1347mergetool.prompt::
1348        Prompt before each invocation of the merge resolution program.
1349
1350notes.displayRef::
1351        The (fully qualified) refname from which to show notes when
1352        showing commit messages.  The value of this variable can be set
1353        to a glob, in which case notes from all matching refs will be
1354        shown.  You may also specify this configuration variable
1355        several times.  A warning will be issued for refs that do not
1356        exist, but a glob that does not match any refs is silently
1357        ignored.
1358+
1359This setting can be overridden with the `GIT_NOTES_DISPLAY_REF`
1360environment variable, which must be a colon separated list of refs or
1361globs.
1362+
1363The effective value of "core.notesRef" (possibly overridden by
1364GIT_NOTES_REF) is also implicitly added to the list of refs to be
1365displayed.
1366
1367notes.rewrite.<command>::
1368        When rewriting commits with <command> (currently `amend` or
1369        `rebase`) and this variable is set to `true`, git
1370        automatically copies your notes from the original to the
1371        rewritten commit.  Defaults to `true`, but see
1372        "notes.rewriteRef" below.
1373
1374notes.rewriteMode::
1375        When copying notes during a rewrite (see the
1376        "notes.rewrite.<command>" option), determines what to do if
1377        the target commit already has a note.  Must be one of
1378        `overwrite`, `concatenate`, or `ignore`.  Defaults to
1379        `concatenate`.
1380+
1381This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
1382environment variable.
1383
1384notes.rewriteRef::
1385        When copying notes during a rewrite, specifies the (fully
1386        qualified) ref whose notes should be copied.  The ref may be a
1387        glob, in which case notes in all matching refs will be copied.
1388        You may also specify this configuration several times.
1389+
1390Does not have a default value; you must configure this variable to
1391enable note rewriting.
1392+
1393This setting can be overridden with the `GIT_NOTES_REWRITE_REF`
1394environment variable, which must be a colon separated list of refs or
1395globs.
1396
1397pack.window::
1398        The size of the window used by linkgit:git-pack-objects[1] when no
1399        window size is given on the command line. Defaults to 10.
1400
1401pack.depth::
1402        The maximum delta depth used by linkgit:git-pack-objects[1] when no
1403        maximum depth is given on the command line. Defaults to 50.
1404
1405pack.windowMemory::
1406        The window memory size limit used by linkgit:git-pack-objects[1]
1407        when no limit is given on the command line.  The value can be
1408        suffixed with "k", "m", or "g".  Defaults to 0, meaning no
1409        limit.
1410
1411pack.compression::
1412        An integer -1..9, indicating the compression level for objects
1413        in a pack file. -1 is the zlib default. 0 means no
1414        compression, and 1..9 are various speed/size tradeoffs, 9 being
1415        slowest.  If not set,  defaults to core.compression.  If that is
1416        not set,  defaults to -1, the zlib default, which is "a default
1417        compromise between speed and compression (currently equivalent
1418        to level 6)."
1419
1420pack.deltaCacheSize::
1421        The maximum memory in bytes used for caching deltas in
1422        linkgit:git-pack-objects[1] before writing them out to a pack.
1423        This cache is used to speed up the writing object phase by not
1424        having to recompute the final delta result once the best match
1425        for all objects is found.  Repacking large repositories on machines
1426        which are tight with memory might be badly impacted by this though,
1427        especially if this cache pushes the system into swapping.
1428        A value of 0 means no limit. The smallest size of 1 byte may be
1429        used to virtually disable this cache. Defaults to 256 MiB.
1430
1431pack.deltaCacheLimit::
1432        The maximum size of a delta, that is cached in
1433        linkgit:git-pack-objects[1]. This cache is used to speed up the
1434        writing object phase by not having to recompute the final delta
1435        result once the best match for all objects is found. Defaults to 1000.
1436
1437pack.threads::
1438        Specifies the number of threads to spawn when searching for best
1439        delta matches.  This requires that linkgit:git-pack-objects[1]
1440        be compiled with pthreads otherwise this option is ignored with a
1441        warning. This is meant to reduce packing time on multiprocessor
1442        machines. The required amount of memory for the delta search window
1443        is however multiplied by the number of threads.
1444        Specifying 0 will cause git to auto-detect the number of CPU's
1445        and set the number of threads accordingly.
1446
1447pack.indexVersion::
1448        Specify the default pack index version.  Valid values are 1 for
1449        legacy pack index used by Git versions prior to 1.5.2, and 2 for
1450        the new pack index with capabilities for packs larger than 4 GB
1451        as well as proper protection against the repacking of corrupted
1452        packs.  Version 2 is the default.  Note that version 2 is enforced
1453        and this config option ignored whenever the corresponding pack is
1454        larger than 2 GB.
1455+
1456If you have an old git that does not understand the version 2 `{asterisk}.idx` file,
1457cloning or fetching over a non native protocol (e.g. "http" and "rsync")
1458that will copy both `{asterisk}.pack` file and corresponding `{asterisk}.idx` file from the
1459other side may give you a repository that cannot be accessed with your
1460older version of git. If the `{asterisk}.pack` file is smaller than 2 GB, however,
1461you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
1462the `{asterisk}.idx` file.
1463
1464pack.packSizeLimit::
1465        The maximum size of a pack.  This setting only affects
1466        packing to a file when repacking, i.e. the git:// protocol
1467        is unaffected.  It can be overridden by the `\--max-pack-size`
1468        option of linkgit:git-repack[1]. The minimum size allowed is
1469        limited to 1 MiB. The default is unlimited.
1470        Common unit suffixes of 'k', 'm', or 'g' are
1471        supported.
1472
1473pager.<cmd>::
1474        Allows turning on or off pagination of the output of a
1475        particular git subcommand when writing to a tty.  If
1476        `\--paginate` or `\--no-pager` is specified on the command line,
1477        it takes precedence over this option.  To disable pagination for
1478        all commands, set `core.pager` or `GIT_PAGER` to `cat`.
1479
1480pretty.<name>::
1481        Alias for a --pretty= format string, as specified in
1482        linkgit:git-log[1]. Any aliases defined here can be used just
1483        as the built-in pretty formats could. For example,
1484        running `git config pretty.changelog "format:{asterisk} %H %s"`
1485        would cause the invocation `git log --pretty=changelog`
1486        to be equivalent to running `git log "--pretty=format:{asterisk} %H %s"`.
1487        Note that an alias with the same name as a built-in format
1488        will be silently ignored.
1489
1490pull.octopus::
1491        The default merge strategy to use when pulling multiple branches
1492        at once.
1493
1494pull.twohead::
1495        The default merge strategy to use when pulling a single branch.
1496
1497push.default::
1498        Defines the action git push should take if no refspec is given
1499        on the command line, no refspec is configured in the remote, and
1500        no refspec is implied by any of the options given on the command
1501        line. Possible values are:
1502+
1503* `nothing` do not push anything.
1504* `matching` push all matching branches.
1505  All branches having the same name in both ends are considered to be
1506  matching. This is the default.
1507* `tracking` push the current branch to its upstream branch.
1508* `current` push the current branch to a branch of the same name.
1509
1510rebase.stat::
1511        Whether to show a diffstat of what changed upstream since the last
1512        rebase. False by default.
1513
1514receive.autogc::
1515        By default, git-receive-pack will run "git-gc --auto" after
1516        receiving data from git-push and updating refs.  You can stop
1517        it by setting this variable to false.
1518
1519receive.fsckObjects::
1520        If it is set to true, git-receive-pack will check all received
1521        objects. It will abort in the case of a malformed object or a
1522        broken link. The result of an abort are only dangling objects.
1523        Defaults to false.
1524
1525receive.unpackLimit::
1526        If the number of objects received in a push is below this
1527        limit then the objects will be unpacked into loose object
1528        files. However if the number of received objects equals or
1529        exceeds this limit then the received pack will be stored as
1530        a pack, after adding any missing delta bases.  Storing the
1531        pack from a push can make the push operation complete faster,
1532        especially on slow filesystems.  If not set, the value of
1533        `transfer.unpackLimit` is used instead.
1534
1535receive.denyDeletes::
1536        If set to true, git-receive-pack will deny a ref update that deletes
1537        the ref. Use this to prevent such a ref deletion via a push.
1538
1539receive.denyCurrentBranch::
1540        If set to true or "refuse", git-receive-pack will deny a ref update
1541        to the currently checked out branch of a non-bare repository.
1542        Such a push is potentially dangerous because it brings the HEAD
1543        out of sync with the index and working tree. If set to "warn",
1544        print a warning of such a push to stderr, but allow the push to
1545        proceed. If set to false or "ignore", allow such pushes with no
1546        message. Defaults to "refuse".
1547
1548receive.denyNonFastForwards::
1549        If set to true, git-receive-pack will deny a ref update which is
1550        not a fast-forward. Use this to prevent such an update via a push,
1551        even if that push is forced. This configuration variable is
1552        set when initializing a shared repository.
1553
1554receive.updateserverinfo::
1555        If set to true, git-receive-pack will run git-update-server-info
1556        after receiving data from git-push and updating refs.
1557
1558remote.<name>.url::
1559        The URL of a remote repository.  See linkgit:git-fetch[1] or
1560        linkgit:git-push[1].
1561
1562remote.<name>.pushurl::
1563        The push URL of a remote repository.  See linkgit:git-push[1].
1564
1565remote.<name>.proxy::
1566        For remotes that require curl (http, https and ftp), the URL to
1567        the proxy to use for that remote.  Set to the empty string to
1568        disable proxying for that remote.
1569
1570remote.<name>.fetch::
1571        The default set of "refspec" for linkgit:git-fetch[1]. See
1572        linkgit:git-fetch[1].
1573
1574remote.<name>.push::
1575        The default set of "refspec" for linkgit:git-push[1]. See
1576        linkgit:git-push[1].
1577
1578remote.<name>.mirror::
1579        If true, pushing to this remote will automatically behave
1580        as if the `\--mirror` option was given on the command line.
1581
1582remote.<name>.skipDefaultUpdate::
1583        If true, this remote will be skipped by default when updating
1584        using linkgit:git-fetch[1] or the `update` subcommand of
1585        linkgit:git-remote[1].
1586
1587remote.<name>.skipFetchAll::
1588        If true, this remote will be skipped by default when updating
1589        using linkgit:git-fetch[1] or the `update` subcommand of
1590        linkgit:git-remote[1].
1591
1592remote.<name>.receivepack::
1593        The default program to execute on the remote side when pushing.  See
1594        option \--receive-pack of linkgit:git-push[1].
1595
1596remote.<name>.uploadpack::
1597        The default program to execute on the remote side when fetching.  See
1598        option \--upload-pack of linkgit:git-fetch-pack[1].
1599
1600remote.<name>.tagopt::
1601        Setting this value to \--no-tags disables automatic tag following when
1602        fetching from remote <name>. Setting it to \--tags will fetch every
1603        tag from remote <name>, even if they are not reachable from remote
1604        branch heads.
1605
1606remote.<name>.vcs::
1607        Setting this to a value <vcs> will cause git to interact with
1608        the remote with the git-remote-<vcs> helper.
1609
1610remotes.<group>::
1611        The list of remotes which are fetched by "git remote update
1612        <group>".  See linkgit:git-remote[1].
1613
1614repack.usedeltabaseoffset::
1615        By default, linkgit:git-repack[1] creates packs that use
1616        delta-base offset. If you need to share your repository with
1617        git older than version 1.4.4, either directly or via a dumb
1618        protocol such as http, then you need to set this option to
1619        "false" and repack. Access from old git versions over the
1620        native protocol are unaffected by this option.
1621
1622rerere.autoupdate::
1623        When set to true, `git-rerere` updates the index with the
1624        resulting contents after it cleanly resolves conflicts using
1625        previously recorded resolution.  Defaults to false.
1626
1627rerere.enabled::
1628        Activate recording of resolved conflicts, so that identical
1629        conflict hunks can be resolved automatically, should they
1630        be encountered again.  linkgit:git-rerere[1] command is by
1631        default enabled if you create `rr-cache` directory under
1632        `$GIT_DIR`, but can be disabled by setting this option to false.
1633
1634sendemail.identity::
1635        A configuration identity. When given, causes values in the
1636        'sendemail.<identity>' subsection to take precedence over
1637        values in the 'sendemail' section. The default identity is
1638        the value of 'sendemail.identity'.
1639
1640sendemail.smtpencryption::
1641        See linkgit:git-send-email[1] for description.  Note that this
1642        setting is not subject to the 'identity' mechanism.
1643
1644sendemail.smtpssl::
1645        Deprecated alias for 'sendemail.smtpencryption = ssl'.
1646
1647sendemail.<identity>.*::
1648        Identity-specific versions of the 'sendemail.*' parameters
1649        found below, taking precedence over those when the this
1650        identity is selected, through command-line or
1651        'sendemail.identity'.

1675
1676sendemail.signedoffcc::
1677        Deprecated alias for 'sendemail.signedoffbycc'.
1678
1679showbranch.default::
1680        The default set of branches for linkgit:git-show-branch[1].
1681        See linkgit:git-show-branch[1].
1682
1683status.relativePaths::
1684        By default, linkgit:git-status[1] shows paths relative to the
1685        current directory. Setting this variable to `false` shows paths
1686        relative to the repository root (this was the default for git
1687        prior to v1.5.4).
1688
1689status.showUntrackedFiles::
1690        By default, linkgit:git-status[1] and linkgit:git-commit[1] show
1691        files which are not currently tracked by Git. Directories which
1692        contain only untracked files, are shown with the directory name
1693        only. Showing untracked files means that Git needs to lstat() all
1694        all the files in the whole repository, which might be slow on some
1695        systems. So, this variable controls how the commands displays
1696        the untracked files. Possible values are:
1697+
1698--
1699        - 'no'     - Show no untracked files
1700        - 'normal' - Shows untracked files and directories
1701        - 'all'    - Shows also individual files in untracked directories.
1702--
1703+
1704If this variable is not specified, it defaults to 'normal'.
1705This variable can be overridden with the -u|--untracked-files option
1706of linkgit:git-status[1] and linkgit:git-commit[1].
1707
1708status.submodulesummary::
1709        Defaults to false.
1710        If this is set to a non zero number or true (identical to -1 or an
1711        unlimited number), the submodule summary will be enabled and a
1712        summary of commits for modified submodules will be shown (see
1713        --summary-limit option of linkgit:git-submodule[1]).
1714
1715tar.umask::
1716        This variable can be used to restrict the permission bits of
1717        tar archive entries.  The default is 0002, which turns off the
1718        world write bit.  The special value "user" indicates that the
1719        archiving user's umask will be used instead.  See umask(2) and
1720        linkgit:git-archive[1].
1721
1722transfer.unpackLimit::
1723        When `fetch.unpackLimit` or `receive.unpackLimit` are
1724        not set, the value of this variable is used instead.
1725        The default value is 100.
1726
1727url.<base>.insteadOf::
1728        Any URL that starts with this value will be rewritten to
1729        start, instead, with <base>. In cases where some site serves a
1730        large number of repositories, and serves them with multiple
1731        access methods, and some users need to use different access
1732        methods, this feature allows people to specify any of the
1733        equivalent URLs and have git automatically rewrite the URL to
1734        the best alternative for the particular user, even for a
1735        never-before-seen repository on the site.  When more than one
1736        insteadOf strings match a given URL, the longest match is used.
1737
1738url.<base>.pushInsteadOf::
1739        Any URL that starts with this value will not be pushed to;
1740        instead, it will be rewritten to start with <base>, and the
1741        resulting URL will be pushed to. In cases where some site serves
1742        a large number of repositories, and serves them with multiple
1743        access methods, some of which do not allow push, this feature
1744        allows people to specify a pull-only URL and have git
1745        automatically use an appropriate URL to push, even for a
1746        never-before-seen repository on the site.  When more than one
1747        pushInsteadOf strings match a given URL, the longest match is
1748        used.  If a remote has an explicit pushurl, git will ignore this
1749        setting for that remote.
1750
1751user.email::
1752        Your email address to be recorded in any newly created commits.
1753        Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and
1754        'EMAIL' environment variables.  See linkgit:git-commit-tree[1].
1755
1756user.name::
1757        Your full name to be recorded in any newly created commits.
1758        Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
1759        environment variables.  See linkgit:git-commit-tree[1].
1760
1761user.signingkey::
1762        If linkgit:git-tag[1] is not selecting the key you want it to
1763        automatically when creating a signed tag, you can override the
1764        default selection with this variable.  This option is passed
1765        unchanged to gpg's --local-user parameter, so you may specify a key
1766        using any method that gpg supports.
1767
1768web.browser::
1769        Specify a web browser that may be used by some commands.
1770        Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
1771        may use it.
