   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.  This ref is expected to contain files named
 524        after the full SHA-1 of the commit they annotate.  The ref
 525        must be fully qualified.
 526+
 527If such a file exists in the given ref, the referenced blob is read, and
 528appended to the commit message, separated by a "Notes (<refname>):"
 529line (shortened to "Notes:" in the case of "refs/notes/commits").  If the
 530given ref itself does not exist, it is not an error, but means that no
 531notes should be printed.
 532+
 533This setting defaults to "refs/notes/commits", and can be overridden by
 534the `GIT_NOTES_REF` environment variable.
 535
 536core.sparseCheckout::
 537        Enable "sparse checkout" feature. See section "Sparse checkout" in
 538        linkgit:git-read-tree[1] for more information.
 539
 540add.ignore-errors::
 541        Tells 'git add' to continue adding files when some files cannot be
 542        added due to indexing errors. Equivalent to the '--ignore-errors'
 543        option of linkgit:git-add[1].
 544
 545alias.*::
 546        Command aliases for the linkgit:git[1] command wrapper - e.g.
 547        after defining "alias.last = cat-file commit HEAD", the invocation
 548        "git last" is equivalent to "git cat-file commit HEAD". To avoid
 549        confusion and troubles with script usage, aliases that
 550        hide existing git commands are ignored. Arguments are split by
 551        spaces, the usual shell quoting and escaping is supported.
 552        quote pair and a backslash can be used to quote them.
 553+
 554If the alias expansion is prefixed with an exclamation point,
 555it will be treated as a shell command.  For example, defining
 556"alias.new = !gitk --all --not ORIG_HEAD", the invocation
 557"git new" is equivalent to running the shell command
 558"gitk --all --not ORIG_HEAD".  Note that shell commands will be
 559executed from the top-level directory of a repository, which may
 560not necessarily be the current directory.
 561
 562am.keepcr::
 563        If true, git-am will call git-mailsplit for patches in mbox format
 564        with parameter '--keep-cr'. In this case git-mailsplit will
 565        not remove `\r` from lines ending with `\r\n`. Can be overrriden
 566        by giving '--no-keep-cr' from the command line.
 567        See linkgit:git-am[1], linkgit:git-mailsplit[1].
 568
 569apply.ignorewhitespace::
 570        When set to 'change', tells 'git apply' to ignore changes in
 571        whitespace, in the same way as the '--ignore-space-change'
 572        option.
 573        When set to one of: no, none, never, false tells 'git apply' to
 574        respect all whitespace differences.
 575        See linkgit:git-apply[1].
 576
 577apply.whitespace::
 578        Tells 'git apply' how to handle whitespaces, in the same way
 579        as the '--whitespace' option. See linkgit:git-apply[1].
 580
 581branch.autosetupmerge::
 582        Tells 'git branch' and 'git checkout' to set up new branches
 583        so that linkgit:git-pull[1] will appropriately merge from the
 584        starting point branch. Note that even if this option is not set,
 585        this behavior can be chosen per-branch using the `--track`
 586        and `--no-track` options. The valid settings are: `false` -- no
 587        automatic setup is done; `true` -- automatic setup is done when the
 588        starting point is a remote branch; `always` -- automatic setup is
 589        done when the starting point is either a local branch or remote
 590        branch. This option defaults to true.
 591
 592branch.autosetuprebase::
 593        When a new branch is created with 'git branch' or 'git checkout'
 594        that tracks another branch, this variable tells git to set
 595        up pull to rebase instead of merge (see "branch.<name>.rebase").
 596        When `never`, rebase is never automatically set to true.
 597        When `local`, rebase is set to true for tracked branches of
 598        other local branches.
 599        When `remote`, rebase is set to true for tracked branches of
 600        remote branches.
 601        When `always`, rebase will be set to true for all tracking
 602        branches.
 603        See "branch.autosetupmerge" for details on how to set up a
 604        branch to track another branch.
 605        This option defaults to never.
 606
 607branch.<name>.remote::
 608        When in branch <name>, it tells 'git fetch' and 'git push' which
 609        remote to fetch from/push to.  It defaults to `origin` if no remote is
 610        configured. `origin` is also used if you are not on any branch.
 611
 612branch.<name>.merge::
 613        Defines, together with branch.<name>.remote, the upstream branch
 614        for the given branch. It tells 'git fetch'/'git pull' which
 615        branch to merge and can also affect 'git push' (see push.default).
 616        When in branch <name>, it tells 'git fetch' the default
 617        refspec to be marked for merging in FETCH_HEAD. The value is
 618        handled like the remote part of a refspec, and must match a
 619        ref which is fetched from the remote given by
 620        "branch.<name>.remote".
 621        The merge information is used by 'git pull' (which at first calls
 622        'git fetch') to lookup the default branch for merging. Without
 623        this option, 'git pull' defaults to merge the first refspec fetched.
 624        Specify multiple values to get an octopus merge.
 625        If you wish to setup 'git pull' so that it merges into <name> from
 626        another branch in the local repository, you can point
 627        branch.<name>.merge to the desired branch, and use the special setting
 628        `.` (a period) for branch.<name>.remote.
 629
 630branch.<name>.mergeoptions::
 631        Sets default options for merging into branch <name>. The syntax and
 632        supported options are the same as those of linkgit:git-merge[1], but
 633        option values containing whitespace characters are currently not
 634        supported.
 635
 636branch.<name>.rebase::
 637        When true, rebase the branch <name> on top of the fetched branch,
 638        instead of merging the default branch from the default remote when
 639        "git pull" is run.
 640        *NOTE*: this is a possibly dangerous operation; do *not* use
 641        it unless you understand the implications (see linkgit:git-rebase[1]
 642        for details).
 643
 644browser.<tool>.cmd::
 645        Specify the command to invoke the specified browser. The
 646        specified command is evaluated in shell with the URLs passed
 647        as arguments. (See linkgit:git-web--browse[1].)
 648
 649browser.<tool>.path::
 650        Override the path for the given tool that may be used to
 651        browse HTML help (see '-w' option in linkgit:git-help[1]) or a
 652        working repository in gitweb (see linkgit:git-instaweb[1]).
 653
 654clean.requireForce::
 655        A boolean to make git-clean do nothing unless given -f
 656        or -n.   Defaults to true.
 657
 658color.branch::
 659        A boolean to enable/disable color in the output of
 660        linkgit:git-branch[1]. May be set to `always`,
 661        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 662        only when the output is to a terminal. Defaults to false.
 663
 664color.branch.<slot>::
 665        Use customized color for branch coloration. `<slot>` is one of
 666        `current` (the current branch), `local` (a local branch),
 667        `remote` (a tracking branch in refs/remotes/), `plain` (other
 668        refs).
 669+
 670The value for these configuration variables is a list of colors (at most
 671two) and attributes (at most one), separated by spaces.  The colors
 672accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`,
 673`magenta`, `cyan` and `white`; the attributes are `bold`, `dim`, `ul`,
 674`blink` and `reverse`.  The first color given is the foreground; the
 675second is the background.  The position of the attribute, if any,
 676doesn't matter.
 677
 678color.diff::
 679        When set to `always`, always use colors in patch.
 680        When false (or `never`), never.  When set to `true` or `auto`, use
 681        colors only when the output is to the terminal. Defaults to false.
 682
 683color.diff.<slot>::
 684        Use customized color for diff colorization.  `<slot>` specifies
 685        which part of the patch to use the specified color, and is one
 686        of `plain` (context text), `meta` (metainformation), `frag`
 687        (hunk header), 'func' (function in hunk header), `old` (removed lines),
 688        `new` (added lines), `commit` (commit headers), or `whitespace`
 689        (highlighting whitespace errors). The values of these variables may be
 690        specified as in color.branch.<slot>.
 691
 692color.grep::
 693        When set to `always`, always highlight matches.  When `false` (or
 694        `never`), never.  When set to `true` or `auto`, use color only
 695        when the output is written to the terminal.  Defaults to `false`.
 696
 697color.grep.<slot>::
 698        Use customized color for grep colorization.  `<slot>` specifies which
 699        part of the line to use the specified color, and is one of
 700+
 701--
 702`context`;;
 703        non-matching text in context lines (when using `-A`, `-B`, or `-C`)
 704`filename`;;
 705        filename prefix (when not using `-h`)
 706`function`;;
 707        function name lines (when using `-p`)
 708`linenumber`;;
 709        line number prefix (when using `-n`)
 710`match`;;
 711        matching text
 712`selected`;;
 713        non-matching text in selected lines
 714`separator`;;
 715        separators between fields on a line (`:`, `-`, and `=`)
 716        and between hunks (`--`)
 717--
 718+
 719The values of these variables may be specified as in color.branch.<slot>.
 720
 721color.interactive::
 722        When set to `always`, always use colors for interactive prompts
 723        and displays (such as those used by "git-add --interactive").
 724        When false (or `never`), never.  When set to `true` or `auto`, use
 725        colors only when the output is to the terminal. Defaults to false.
 726
 727color.interactive.<slot>::
 728        Use customized color for 'git add --interactive'
 729        output. `<slot>` may be `prompt`, `header`, `help` or `error`, for
 730        four distinct types of normal output from interactive
 731        commands.  The values of these variables may be specified as
 732        in color.branch.<slot>.
 733
 734color.pager::
 735        A boolean to enable/disable colored output when the pager is in
 736        use (default is true).
 737
 738color.showbranch::
 739        A boolean to enable/disable color in the output of
 740        linkgit:git-show-branch[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::
 745        A boolean to enable/disable color in the output of
 746        linkgit:git-status[1]. May be set to `always`,
 747        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 748        only when the output is to a terminal. Defaults to false.
 749
 750color.status.<slot>::
 751        Use customized color for status colorization. `<slot>` is
 752        one of `header` (the header text of the status message),
 753        `added` or `updated` (files which are added but not committed),
 754        `changed` (files which are changed but not added in the index),
 755        `untracked` (files which are not tracked by git), or
 756        `nobranch` (the color the 'no branch' warning is shown in, defaulting
 757        to red). The values of these variables may be specified as in
 758        color.branch.<slot>.
 759
 760color.ui::
 761        When set to `always`, always use colors in all git commands which
 762        are capable of colored output. When false (or `never`), never. When
 763        set to `true` or `auto`, use colors only when the output is to the
 764        terminal. When more specific variables of color.* are set, they always
 765        take precedence over this setting. Defaults to false.
 766
 767commit.status::
 768        A boolean to enable/disable inclusion of status information in the
 769        commit message template when using an editor to prepare the commit
 770        message.  Defaults to true.
 771
 772commit.template::
 773        Specify a file to use as the template for new commit messages.
 774        "{tilde}/" is expanded to the value of `$HOME` and "{tilde}user/" to the
 775        specified user's home directory.
 776
 777diff.autorefreshindex::
 778        When using 'git diff' to compare with work tree
 779        files, do not consider stat-only change as changed.
 780        Instead, silently run `git update-index --refresh` to
 781        update the cached stat information for paths whose
 782        contents in the work tree match the contents in the
 783        index.  This option defaults to true.  Note that this
 784        affects only 'git diff' Porcelain, and not lower level
 785        'diff' commands such as 'git diff-files'.
 786
 787diff.external::
 788        If this config variable is set, diff generation is not
 789        performed using the internal diff machinery, but using the
 790        given command.  Can be overridden with the `GIT_EXTERNAL_DIFF'
 791        environment variable.  The command is called with parameters
 792        as described under "git Diffs" in linkgit:git[1].  Note: if
 793        you want to use an external diff program only on a subset of
 794        your files, you might want to use linkgit:gitattributes[5] instead.
 795
 796diff.mnemonicprefix::
 797        If set, 'git diff' uses a prefix pair that is different from the
 798        standard "a/" and "b/" depending on what is being compared.  When
 799        this configuration is in effect, reverse diff output also swaps
 800        the order of the prefixes:
 801`git diff`;;
 802        compares the (i)ndex and the (w)ork tree;
 803`git diff HEAD`;;
 804         compares a (c)ommit and the (w)ork tree;
 805`git diff --cached`;;
 806        compares a (c)ommit and the (i)ndex;
 807`git diff HEAD:file1 file2`;;
 808        compares an (o)bject and a (w)ork tree entity;
 809`git diff --no-index a b`;;
 810        compares two non-git things (1) and (2).
 811
 812diff.renameLimit::
 813        The number of files to consider when performing the copy/rename
 814        detection; equivalent to the 'git diff' option '-l'.
 815
 816diff.renames::
 817        Tells git to detect renames.  If set to any boolean value, it
 818        will enable basic rename detection.  If set to "copies" or
 819        "copy", it will detect copies, as well.
 820
 821diff.suppressBlankEmpty::
 822        A boolean to inhibit the standard behavior of printing a space
 823        before each empty output line. Defaults to false.
 824
 825diff.tool::
 826        Controls which diff tool is used.  `diff.tool` overrides
 827        `merge.tool` when used by linkgit:git-difftool[1] and has
 828        the same valid values as `merge.tool` minus "tortoisemerge"
 829        and plus "kompare".
 830
 831difftool.<tool>.path::
 832        Override the path for the given tool.  This is useful in case
 833        your tool is not in the PATH.
 834
 835difftool.<tool>.cmd::
 836        Specify the command to invoke the specified diff tool.
 837        The specified command is evaluated in shell with the following
 838        variables available:  'LOCAL' is set to the name of the temporary
 839        file containing the contents of the diff pre-image and 'REMOTE'
 840        is set to the name of the temporary file containing the contents
 841        of the diff post-image.
 842
 843difftool.prompt::
 844        Prompt before each invocation of the diff tool.
 845
 846diff.wordRegex::
 847        A POSIX Extended Regular Expression used to determine what is a "word"
 848        when performing word-by-word difference calculations.  Character
 849        sequences that match the regular expression are "words", all other
 850        characters are *ignorable* whitespace.
 851
 852fetch.unpackLimit::
 853        If the number of objects fetched over the git native
 854        transfer is below this
 855        limit, then the objects will be unpacked into loose object
 856        files. However if the number of received objects equals or
 857        exceeds this limit then the received pack will be stored as
 858        a pack, after adding any missing delta bases.  Storing the
 859        pack from a push can make the push operation complete faster,
 860        especially on slow filesystems.  If not set, the value of
 861        `transfer.unpackLimit` is used instead.
 862
 863format.attach::
 864        Enable multipart/mixed attachments as the default for
 865        'format-patch'.  The value can also be a double quoted string
 866        which will enable attachments as the default and set the
 867        value as the boundary.  See the --attach option in
 868        linkgit:git-format-patch[1].
 869
 870format.numbered::
 871        A boolean which can enable or disable sequence numbers in patch
 872        subjects.  It defaults to "auto" which enables it only if there
 873        is more than one patch.  It can be enabled or disabled for all
 874        messages by setting it to "true" or "false".  See --numbered
 875        option in linkgit:git-format-patch[1].
 876
 877format.headers::
 878        Additional email headers to include in a patch to be submitted
 879        by mail.  See linkgit:git-format-patch[1].
 880
 881format.cc::
 882        Additional "Cc:" headers to include in a patch to be submitted
 883        by mail.  See the --cc option in linkgit:git-format-patch[1].
 884
 885format.subjectprefix::
 886        The default for format-patch is to output files with the '[PATCH]'
 887        subject prefix. Use this variable to change that prefix.
 888
 889format.suffix::
 890        The default for format-patch is to output files with the suffix
 891        `.patch`. Use this variable to change that suffix (make sure to
 892        include the dot if you want it).
 893
 894format.pretty::
 895        The default pretty format for log/show/whatchanged command,
 896        See linkgit:git-log[1], linkgit:git-show[1],
 897        linkgit:git-whatchanged[1].
 898
 899format.thread::
 900        The default threading style for 'git format-patch'.  Can be
 901        a boolean value, or `shallow` or `deep`.  `shallow` threading
 902        makes every mail a reply to the head of the series,
 903        where the head is chosen from the cover letter, the
 904        `\--in-reply-to`, and the first patch mail, in this order.
 905        `deep` threading makes every mail a reply to the previous one.
 906        A true boolean value is the same as `shallow`, and a false
 907        value disables threading.
 908
 909format.signoff::
 910    A boolean value which lets you enable the `-s/--signoff` option of
 911    format-patch by default. *Note:* Adding the Signed-off-by: line to a
 912    patch should be a conscious act and means that you certify you have
 913    the rights to submit this work under the same open source license.
 914    Please see the 'SubmittingPatches' document for further discussion.
 915
 916gc.aggressiveWindow::
 917        The window size parameter used in the delta compression
 918        algorithm used by 'git gc --aggressive'.  This defaults
 919        to 250.
 920
 921gc.auto::
 922        When there are approximately more than this many loose
 923        objects in the repository, `git gc --auto` will pack them.
 924        Some Porcelain commands use this command to perform a
 925        light-weight garbage collection from time to time.  The
 926        default value is 6700.  Setting this to 0 disables it.
 927
 928gc.autopacklimit::
 929        When there are more than this many packs that are not
 930        marked with `*.keep` file in the repository, `git gc
 931        --auto` consolidates them into one larger pack.  The
 932        default value is 50.  Setting this to 0 disables it.
 933
 934gc.packrefs::
 935        Running `git pack-refs` in a repository renders it
 936        unclonable by Git versions prior to 1.5.1.2 over dumb
 937        transports such as HTTP.  This variable determines whether
 938        'git gc' runs `git pack-refs`. This can be set to `nobare`
 939        to enable it within all non-bare repos or it can be set to a
 940        boolean value.  The default is `true`.
 941
 942gc.pruneexpire::
 943        When 'git gc' is run, it will call 'prune --expire 2.weeks.ago'.
 944        Override the grace period with this config variable.  The value
 945        "now" may be used to disable this  grace period and always prune
 946        unreachable objects immediately.
 947
 948gc.reflogexpire::
 949gc.<pattern>.reflogexpire::
 950        'git reflog expire' removes reflog entries older than
 951        this time; defaults to 90 days.  With "<pattern>" (e.g.
 952        "refs/stash") in the middle the setting applies only to
 953        the refs that match the <pattern>.
 954
 955gc.reflogexpireunreachable::
 956gc.<ref>.reflogexpireunreachable::
 957        'git reflog expire' removes reflog entries older than
 958        this time and are not reachable from the current tip;
 959        defaults to 30 days.  With "<pattern>" (e.g. "refs/stash")
 960        in the middle, the setting applies only to the refs that
 961        match the <pattern>.
 962
 963gc.rerereresolved::
 964        Records of conflicted merge you resolved earlier are
 965        kept for this many days when 'git rerere gc' is run.
 966        The default is 60 days.  See linkgit:git-rerere[1].
 967
 968gc.rerereunresolved::
 969        Records of conflicted merge you have not resolved are
 970        kept for this many days when 'git rerere gc' is run.
 971        The default is 15 days.  See linkgit:git-rerere[1].
 972
 973gitcvs.commitmsgannotation::
 974        Append this string to each commit message. Set to empty string
 975        to disable this feature. Defaults to "via git-CVS emulator".
 976
 977gitcvs.enabled::
 978        Whether the CVS server interface is enabled for this repository.
 979        See linkgit:git-cvsserver[1].
 980
 981gitcvs.logfile::
 982        Path to a log file where the CVS server interface well... logs
 983        various stuff. See linkgit:git-cvsserver[1].
 984
 985gitcvs.usecrlfattr::
 986        If true, the server will look up the `crlf` attribute for
 987        files to determine the '-k' modes to use. If `crlf` is set,
 988        the '-k' mode will be left blank, so cvs clients will
 989        treat it as text. If `crlf` is explicitly unset, the file
 990        will be set with '-kb' mode, which suppresses any newline munging
 991        the client might otherwise do. If `crlf` is not specified,
 992        then 'gitcvs.allbinary' is used. See linkgit:gitattributes[5].
 993
 994gitcvs.allbinary::
 995        This is used if 'gitcvs.usecrlfattr' does not resolve
 996        the correct '-kb' mode to use. If true, all
 997        unresolved files are sent to the client in
 998        mode '-kb'. This causes the client to treat them
 999        as binary files, which suppresses any newline munging it
1000        otherwise might do. Alternatively, if it is set to "guess",
1001        then the contents of the file are examined to decide if
1002        it is binary, similar to 'core.autocrlf'.
1003
1004gitcvs.dbname::
1005        Database used by git-cvsserver to cache revision information
1006        derived from the git repository. The exact meaning depends on the
1007        used database driver, for SQLite (which is the default driver) this
1008        is a filename. Supports variable substitution (see
1009        linkgit:git-cvsserver[1] for details). May not contain semicolons (`;`).
1010        Default: '%Ggitcvs.%m.sqlite'
1011
1012gitcvs.dbdriver::
1013        Used Perl DBI driver. You can specify any available driver
1014        for this here, but it might not work. git-cvsserver is tested
1015        with 'DBD::SQLite', reported to work with 'DBD::Pg', and
1016        reported *not* to work with 'DBD::mysql'. Experimental feature.
1017        May not contain double colons (`:`). Default: 'SQLite'.
1018        See linkgit:git-cvsserver[1].
1019
1020gitcvs.dbuser, gitcvs.dbpass::
1021        Database user and password. Only useful if setting 'gitcvs.dbdriver',
1022        since SQLite has no concept of database users and/or passwords.
1023        'gitcvs.dbuser' supports variable substitution (see
1024        linkgit:git-cvsserver[1] for details).
1025
1026gitcvs.dbTableNamePrefix::
1027        Database table name prefix.  Prepended to the names of any
1028        database tables used, allowing a single database to be used
1029        for several repositories.  Supports variable substitution (see
1030        linkgit:git-cvsserver[1] for details).  Any non-alphabetic
1031        characters will be replaced with underscores.
1032
1033All gitcvs variables except for 'gitcvs.usecrlfattr' and
1034'gitcvs.allbinary' can also be specified as
1035'gitcvs.<access_method>.<varname>' (where 'access_method'
1036is one of "ext" and "pserver") to make them apply only for the given
1037access method.
1038
1039gui.commitmsgwidth::
1040        Defines how wide the commit message window is in the
1041        linkgit:git-gui[1]. "75" is the default.
1042
1043gui.diffcontext::
1044        Specifies how many context lines should be used in calls to diff
1045        made by the linkgit:git-gui[1]. The default is "5".
1046
1047gui.encoding::
1048        Specifies the default encoding to use for displaying of
1049        file contents in linkgit:git-gui[1] and linkgit:gitk[1].
1050        It can be overridden by setting the 'encoding' attribute
1051        for relevant files (see linkgit:gitattributes[5]).
1052        If this option is not set, the tools default to the
1053        locale encoding.
1054
1055gui.matchtrackingbranch::
1056        Determines if new branches created with linkgit:git-gui[1] should
1057        default to tracking remote branches with matching names or
1058        not. Default: "false".
1059
1060gui.newbranchtemplate::
1061        Is used as suggested name when creating new branches using the
1062        linkgit:git-gui[1].
1063
1064gui.pruneduringfetch::
1065        "true" if linkgit:git-gui[1] should prune tracking branches when
1066        performing a fetch. The default value is "false".
1067
1068gui.trustmtime::
1069        Determines if linkgit:git-gui[1] should trust the file modification
1070        timestamp or not. By default the timestamps are not trusted.
1071
1072gui.spellingdictionary::
1073        Specifies the dictionary used for spell checking commit messages in
1074        the linkgit:git-gui[1]. When set to "none" spell checking is turned
1075        off.
1076
1077gui.fastcopyblame::
1078        If true, 'git gui blame' uses `-C` instead of `-C -C` for original
1079        location detection. It makes blame significantly faster on huge
1080        repositories at the expense of less thorough copy detection.
1081
1082gui.copyblamethreshold::
1083        Specifies the threshold to use in 'git gui blame' original location
1084        detection, measured in alphanumeric characters. See the
1085        linkgit:git-blame[1] manual for more information on copy detection.
1086
1087gui.blamehistoryctx::
1088        Specifies the radius of history context in days to show in
1089        linkgit:gitk[1] for the selected commit, when the `Show History
1090        Context` menu item is invoked from 'git gui blame'. If this
1091        variable is set to zero, the whole history is shown.
1092
1093guitool.<name>.cmd::
1094        Specifies the shell command line to execute when the corresponding item
1095        of the linkgit:git-gui[1] `Tools` menu is invoked. This option is
1096        mandatory for every tool. The command is executed from the root of
1097        the working directory, and in the environment it receives the name of
1098        the tool as 'GIT_GUITOOL', the name of the currently selected file as
1099        'FILENAME', and the name of the current branch as 'CUR_BRANCH' (if
1100        the head is detached, 'CUR_BRANCH' is empty).
1101
1102guitool.<name>.needsfile::
1103        Run the tool only if a diff is selected in the GUI. It guarantees
1104        that 'FILENAME' is not empty.
1105
1106guitool.<name>.noconsole::
1107        Run the command silently, without creating a window to display its
1108        output.
1109
1110guitool.<name>.norescan::
1111        Don't rescan the working directory for changes after the tool
1112        finishes execution.
1113
1114guitool.<name>.confirm::
1115        Show a confirmation dialog before actually running the tool.
1116
1117guitool.<name>.argprompt::
1118        Request a string argument from the user, and pass it to the tool
1119        through the 'ARGS' environment variable. Since requesting an
1120        argument implies confirmation, the 'confirm' option has no effect
1121        if this is enabled. If the option is set to 'true', 'yes', or '1',
1122        the dialog uses a built-in generic prompt; otherwise the exact
1123        value of the variable is used.
1124
1125guitool.<name>.revprompt::
1126        Request a single valid revision from the user, and set the
1127        'REVISION' environment variable. In other aspects this option
1128        is similar to 'argprompt', and can be used together with it.
1129
1130guitool.<name>.revunmerged::
1131        Show only unmerged branches in the 'revprompt' subdialog.
1132        This is useful for tools similar to merge or rebase, but not
1133        for things like checkout or reset.
1134
1135guitool.<name>.title::
1136        Specifies the title to use for the prompt dialog. The default
1137        is the tool name.
1138
1139guitool.<name>.prompt::
1140        Specifies the general prompt string to display at the top of
1141        the dialog, before subsections for 'argprompt' and 'revprompt'.
1142        The default value includes the actual command.
1143
1144help.browser::
1145        Specify the browser that will be used to display help in the
1146        'web' format. See linkgit:git-help[1].
1147
1148help.format::
1149        Override the default help format used by linkgit:git-help[1].
1150        Values 'man', 'info', 'web' and 'html' are supported. 'man' is
1151        the default. 'web' and 'html' are the same.
1152
1153help.autocorrect::
1154        Automatically correct and execute mistyped commands after
1155        waiting for the given number of deciseconds (0.1 sec). If more
1156        than one command can be deduced from the entered text, nothing
1157        will be executed.  If the value of this option is negative,
1158        the corrected command will be executed immediately. If the
1159        value is 0 - the command will be just shown but not executed.
1160        This is the default.
1161
1162http.proxy::
1163        Override the HTTP proxy, normally configured using the 'http_proxy'
1164        environment variable (see linkgit:curl[1]).  This can be overridden
1165        on a per-remote basis; see remote.<name>.proxy
1166
1167http.sslVerify::
1168        Whether to verify the SSL certificate when fetching or pushing
1169        over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
1170        variable.
1171
1172http.sslCert::
1173        File containing the SSL certificate when fetching or pushing
1174        over HTTPS. Can be overridden by the 'GIT_SSL_CERT' environment
1175        variable.
1176
1177http.sslKey::
1178        File containing the SSL private key when fetching or pushing
1179        over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment
1180        variable.
1181
1182http.sslCertPasswordProtected::
1183        Enable git's password prompt for the SSL certificate.  Otherwise
1184        OpenSSL will prompt the user, possibly many times, if the
1185        certificate or private key is encrypted.  Can be overridden by the
1186        'GIT_SSL_CERT_PASSWORD_PROTECTED' environment variable.
1187
1188http.sslCAInfo::
1189        File containing the certificates to verify the peer with when
1190        fetching or pushing over HTTPS. Can be overridden by the
1191        'GIT_SSL_CAINFO' environment variable.
1192
1193http.sslCAPath::
1194        Path containing files with the CA certificates to verify the peer
1195        with when fetching or pushing over HTTPS. Can be overridden
1196        by the 'GIT_SSL_CAPATH' environment variable.
1197
1198http.maxRequests::
1199        How many HTTP requests to launch in parallel. Can be overridden
1200        by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5.
1201
1202http.minSessions::
1203        The number of curl sessions (counted across slots) to be kept across
1204        requests. They will not be ended with curl_easy_cleanup() until
1205        http_cleanup() is invoked. If USE_CURL_MULTI is not defined, this
1206        value will be capped at 1. Defaults to 1.
1207
1208http.postBuffer::
1209        Maximum size in bytes of the buffer used by smart HTTP
1210        transports when POSTing data to the remote system.
1211        For requests larger than this buffer size, HTTP/1.1 and
1212        Transfer-Encoding: chunked is used to avoid creating a
1213        massive pack file locally.  Default is 1 MiB, which is
1214        sufficient for most requests.
1215
1216http.lowSpeedLimit, http.lowSpeedTime::
1217        If the HTTP transfer speed is less than 'http.lowSpeedLimit'
1218        for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
1219        Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and
1220        'GIT_HTTP_LOW_SPEED_TIME' environment variables.
1221
1222http.noEPSV::
1223        A boolean which disables using of EPSV ftp command by curl.
1224        This can helpful with some "poor" ftp servers which don't
1225        support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
1226        environment variable. Default is false (curl will use EPSV).
1227
1228i18n.commitEncoding::
1229        Character encoding the commit messages are stored in; git itself
1230        does not care per se, but this information is necessary e.g. when
1231        importing commits from emails or in the gitk graphical history
1232        browser (and possibly at other places in the future or in other
1233        porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.
1234
1235i18n.logOutputEncoding::
1236        Character encoding the commit messages are converted to when
1237        running 'git log' and friends.
1238
1239imap::
1240        The configuration variables in the 'imap' section are described
1241        in linkgit:git-imap-send[1].
1242
1243init.templatedir::
1244        Specify the directory from which templates will be copied.
1245        (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].)
1246
1247instaweb.browser::
1248        Specify the program that will be used to browse your working
1249        repository in gitweb. See linkgit:git-instaweb[1].
1250
1251instaweb.httpd::
1252        The HTTP daemon command-line to start gitweb on your working
1253        repository. See linkgit:git-instaweb[1].
1254
1255instaweb.local::
1256        If true the web server started by linkgit:git-instaweb[1] will
1257        be bound to the local IP (127.0.0.1).
1258
1259instaweb.modulepath::
1260        The module path for an apache httpd used by linkgit:git-instaweb[1].
1261
1262instaweb.port::
1263        The port number to bind the gitweb httpd to. See
1264        linkgit:git-instaweb[1].
1265
1266interactive.singlekey::
1267        In interactive commands, allow the user to provide one-letter
1268        input with a single key (i.e., without hitting enter).
1269        Currently this is used only by the `\--patch` mode of
1270        linkgit:git-add[1].  Note that this setting is silently
1271        ignored if portable keystroke input is not available.
1272
1273log.date::
1274        Set default date-time mode for the log command. Setting log.date
1275        value is similar to using 'git log'\'s --date option. The value is one of the
1276        following alternatives: {relative,local,default,iso,rfc,short}.
1277        See linkgit:git-log[1].
1278
1279log.decorate::
1280        Print out the ref names of any commits that are shown by the log
1281        command. If 'short' is specified, the ref name prefixes 'refs/heads/',
1282        'refs/tags/' and 'refs/remotes/' will not be printed. If 'full' is
1283        specified, the full ref name (including prefix) will be printed.
1284        This is the same as the log commands '--decorate' option.
1285
1286log.showroot::
1287        If true, the initial commit will be shown as a big creation event.
1288        This is equivalent to a diff against an empty tree.
1289        Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
1290        normally hide the root commit will now show it. True by default.
1291
1292mailmap.file::
1293        The location of an augmenting mailmap file. The default
1294        mailmap, located in the root of the repository, is loaded
1295        first, then the mailmap file pointed to by this variable.
1296        The location of the mailmap file may be in a repository
1297        subdirectory, or somewhere outside of the repository itself.
1298        See linkgit:git-shortlog[1] and linkgit:git-blame[1].
1299
1300man.viewer::
1301        Specify the programs that may be used to display help in the
1302        'man' format. See linkgit:git-help[1].
1303
1304man.<tool>.cmd::
1305        Specify the command to invoke the specified man viewer. The
1306        specified command is evaluated in shell with the man page
1307        passed as argument. (See linkgit:git-help[1].)
1308
1309man.<tool>.path::
1310        Override the path for the given tool that may be used to
1311        display help in the 'man' format. See linkgit:git-help[1].
1312
1313include::merge-config.txt[]
1314
1315mergetool.<tool>.path::
1316        Override the path for the given tool.  This is useful in case
1317        your tool is not in the PATH.
1318
1319mergetool.<tool>.cmd::
1320        Specify the command to invoke the specified merge tool.  The
1321        specified command is evaluated in shell with the following
1322        variables available: 'BASE' is the name of a temporary file
1323        containing the common base of the files to be merged, if available;
1324        'LOCAL' is the name of a temporary file containing the contents of
1325        the file on the current branch; 'REMOTE' is the name of a temporary
1326        file containing the contents of the file from the branch being
1327        merged; 'MERGED' contains the name of the file to which the merge
1328        tool should write the results of a successful merge.
1329
1330mergetool.<tool>.trustExitCode::
1331        For a custom merge command, specify whether the exit code of
1332        the merge command can be used to determine whether the merge was
1333        successful.  If this is not set to true then the merge target file
1334        timestamp is checked and the merge assumed to have been successful
1335        if the file has been updated, otherwise the user is prompted to
1336        indicate the success of the merge.
1337
1338mergetool.keepBackup::
1339        After performing a merge, the original file with conflict markers
1340        can be saved as a file with a `.orig` extension.  If this variable
1341        is set to `false` then this file is not preserved.  Defaults to
1342        `true` (i.e. keep the backup files).
1343
1344mergetool.keepTemporaries::
1345        When invoking a custom merge tool, git uses a set of temporary
1346        files to pass to the tool. If the tool returns an error and this
1347        variable is set to `true`, then these temporary files will be
1348        preserved, otherwise they will be removed after the tool has
1349        exited. Defaults to `false`.
1350
1351mergetool.prompt::
1352        Prompt before each invocation of the merge resolution program.
1353
1354notes.displayRef::
1355        The (fully qualified) refname from which to show notes when
1356        showing commit messages.  The value of this variable can be set
1357        to a glob, in which case notes from all matching refs will be
1358        shown.  You may also specify this configuration variable
1359        several times.  A warning will be issued for refs that do not
1360        exist, but a glob that does not match any refs is silently
1361        ignored.
1362+
1363This setting can be overridden with the `GIT_NOTES_DISPLAY_REF`
1364environment variable, which must be a colon separated list of refs or
1365globs.
1366+
1367The effective value of "core.notesRef" (possibly overridden by
1368GIT_NOTES_REF) is also implicitly added to the list of refs to be
1369displayed.
1370
1371notes.rewrite.<command>::
1372        When rewriting commits with <command> (currently `amend` or
1373        `rebase`) and this variable is set to `true`, git
1374        automatically copies your notes from the original to the
1375        rewritten commit.  Defaults to `true`, but see
1376        "notes.rewriteRef" below.
1377
1378notes.rewriteMode::
1379        When copying notes during a rewrite (see the
1380        "notes.rewrite.<command>" option), determines what to do if
1381        the target commit already has a note.  Must be one of
1382        `overwrite`, `concatenate`, or `ignore`.  Defaults to
1383        `concatenate`.
1384+
1385This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
1386environment variable.
1387
1388notes.rewriteRef::
1389        When copying notes during a rewrite, specifies the (fully
1390        qualified) ref whose notes should be copied.  The ref may be a
1391        glob, in which case notes in all matching refs will be copied.
1392        You may also specify this configuration several times.
1393+
1394Does not have a default value; you must configure this variable to
1395enable note rewriting.
1396+
1397This setting can be overridden with the `GIT_NOTES_REWRITE_REF`
1398environment variable, which must be a colon separated list of refs or
1399globs.
1400
1401pack.window::
1402        The size of the window used by linkgit:git-pack-objects[1] when no
1403        window size is given on the command line. Defaults to 10.
1404
1405pack.depth::
1406        The maximum delta depth used by linkgit:git-pack-objects[1] when no
1407        maximum depth is given on the command line. Defaults to 50.
1408
1409pack.windowMemory::
1410        The window memory size limit used by linkgit:git-pack-objects[1]
1411        when no limit is given on the command line.  The value can be
1412        suffixed with "k", "m", or "g".  Defaults to 0, meaning no
1413        limit.
1414
1415pack.compression::
1416        An integer -1..9, indicating the compression level for objects
1417        in a pack file. -1 is the zlib default. 0 means no
1418        compression, and 1..9 are various speed/size tradeoffs, 9 being
1419        slowest.  If not set,  defaults to core.compression.  If that is
1420        not set,  defaults to -1, the zlib default, which is "a default
1421        compromise between speed and compression (currently equivalent
1422        to level 6)."
1423
1424pack.deltaCacheSize::
1425        The maximum memory in bytes used for caching deltas in
1426        linkgit:git-pack-objects[1] before writing them out to a pack.
1427        This cache is used to speed up the writing object phase by not
1428        having to recompute the final delta result once the best match
1429        for all objects is found.  Repacking large repositories on machines
1430        which are tight with memory might be badly impacted by this though,
1431        especially if this cache pushes the system into swapping.
1432        A value of 0 means no limit. The smallest size of 1 byte may be
1433        used to virtually disable this cache. Defaults to 256 MiB.
1434
1435pack.deltaCacheLimit::
1436        The maximum size of a delta, that is cached in
1437        linkgit:git-pack-objects[1]. This cache is used to speed up the
1438        writing object phase by not having to recompute the final delta
1439        result once the best match for all objects is found. Defaults to 1000.
1440
1441pack.threads::
1442        Specifies the number of threads to spawn when searching for best
1443        delta matches.  This requires that linkgit:git-pack-objects[1]
1444        be compiled with pthreads otherwise this option is ignored with a
1445        warning. This is meant to reduce packing time on multiprocessor
1446        machines. The required amount of memory for the delta search window
1447        is however multiplied by the number of threads.
1448        Specifying 0 will cause git to auto-detect the number of CPU's
1449        and set the number of threads accordingly.
1450
1451pack.indexVersion::
1452        Specify the default pack index version.  Valid values are 1 for
1453        legacy pack index used by Git versions prior to 1.5.2, and 2 for
1454        the new pack index with capabilities for packs larger than 4 GB
1455        as well as proper protection against the repacking of corrupted
1456        packs.  Version 2 is the default.  Note that version 2 is enforced
1457        and this config option ignored whenever the corresponding pack is
1458        larger than 2 GB.
1459+
1460If you have an old git that does not understand the version 2 `{asterisk}.idx` file,
1461cloning or fetching over a non native protocol (e.g. "http" and "rsync")
1462that will copy both `{asterisk}.pack` file and corresponding `{asterisk}.idx` file from the
1463other side may give you a repository that cannot be accessed with your
1464older version of git. If the `{asterisk}.pack` file is smaller than 2 GB, however,
1465you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
1466the `{asterisk}.idx` file.
1467
1468pack.packSizeLimit::
1469        The maximum size of a pack.  This setting only affects
1470        packing to a file when repacking, i.e. the git:// protocol
1471        is unaffected.  It can be overridden by the `\--max-pack-size`
1472        option of linkgit:git-repack[1]. The minimum size allowed is
1473        limited to 1 MiB. The default is unlimited.
1474        Common unit suffixes of 'k', 'm', or 'g' are
1475        supported.
1476
1477pager.<cmd>::
1478        Allows turning on or off pagination of the output of a
1479        particular git subcommand when writing to a tty.  If
1480        `\--paginate` or `\--no-pager` is specified on the command line,
1481        it takes precedence over this option.  To disable pagination for
1482        all commands, set `core.pager` or `GIT_PAGER` to `cat`.
1483
1484pull.octopus::
1485        The default merge strategy to use when pulling multiple branches
1486        at once.
1487
1488pull.twohead::
1489        The default merge strategy to use when pulling a single branch.
1490
1491push.default::
1492        Defines the action git push should take if no refspec is given
1493        on the command line, no refspec is configured in the remote, and
1494        no refspec is implied by any of the options given on the command
1495        line. Possible values are:
1496+
1497* `nothing` do not push anything.
1498* `matching` push all matching branches.
1499  All branches having the same name in both ends are considered to be
1500  matching. This is the default.
1501* `tracking` push the current branch to its upstream branch.
1502* `current` push the current branch to a branch of the same name.
1503
1504rebase.stat::
1505        Whether to show a diffstat of what changed upstream since the last
1506        rebase. False by default.
1507
1508receive.autogc::
1509        By default, git-receive-pack will run "git-gc --auto" after
1510        receiving data from git-push and updating refs.  You can stop
1511        it by setting this variable to false.
1512
1513receive.fsckObjects::
1514        If it is set to true, git-receive-pack will check all received
1515        objects. It will abort in the case of a malformed object or a
1516        broken link. The result of an abort are only dangling objects.
1517        Defaults to false.
1518
1519receive.unpackLimit::
1520        If the number of objects received in a push is below this
1521        limit then the objects will be unpacked into loose object
1522        files. However if the number of received objects equals or
1523        exceeds this limit then the received pack will be stored as
1524        a pack, after adding any missing delta bases.  Storing the
1525        pack from a push can make the push operation complete faster,
1526        especially on slow filesystems.  If not set, the value of
1527        `transfer.unpackLimit` is used instead.
1528
1529receive.denyDeletes::
1530        If set to true, git-receive-pack will deny a ref update that deletes
1531        the ref. Use this to prevent such a ref deletion via a push.
1532
1533receive.denyCurrentBranch::
1534        If set to true or "refuse", git-receive-pack will deny a ref update
1535        to the currently checked out branch of a non-bare repository.
1536        Such a push is potentially dangerous because it brings the HEAD
1537        out of sync with the index and working tree. If set to "warn",
1538        print a warning of such a push to stderr, but allow the push to
1539        proceed. If set to false or "ignore", allow such pushes with no
1540        message. Defaults to "refuse".
1541
1542receive.denyNonFastForwards::
1543        If set to true, git-receive-pack will deny a ref update which is
1544        not a fast-forward. Use this to prevent such an update via a push,
1545        even if that push is forced. This configuration variable is
1546        set when initializing a shared repository.
1547
1548receive.updateserverinfo::
1549        If set to true, git-receive-pack will run git-update-server-info
1550        after receiving data from git-push and updating refs.
1551
1552remote.<name>.url::
1553        The URL of a remote repository.  See linkgit:git-fetch[1] or
1554        linkgit:git-push[1].
1555
1556remote.<name>.pushurl::
1557        The push URL of a remote repository.  See linkgit:git-push[1].
1558
1559remote.<name>.proxy::
1560        For remotes that require curl (http, https and ftp), the URL to
1561        the proxy to use for that remote.  Set to the empty string to
1562        disable proxying for that remote.
1563
1564remote.<name>.fetch::
1565        The default set of "refspec" for linkgit:git-fetch[1]. See
1566        linkgit:git-fetch[1].
1567
1568remote.<name>.push::
1569        The default set of "refspec" for linkgit:git-push[1]. See
1570        linkgit:git-push[1].
1571
1572remote.<name>.mirror::
1573        If true, pushing to this remote will automatically behave
1574        as if the `\--mirror` option was given on the command line.
1575
1576remote.<name>.skipDefaultUpdate::
1577        If true, this remote will be skipped by default when updating
1578        using linkgit:git-fetch[1] or the `update` subcommand of
1579        linkgit:git-remote[1].
1580
1581remote.<name>.skipFetchAll::
1582        If true, this remote will be skipped by default when updating
1583        using linkgit:git-fetch[1] or the `update` subcommand of
1584        linkgit:git-remote[1].
1585
1586remote.<name>.receivepack::
1587        The default program to execute on the remote side when pushing.  See
1588        option \--receive-pack of linkgit:git-push[1].
1589
1590remote.<name>.uploadpack::
1591        The default program to execute on the remote side when fetching.  See
1592        option \--upload-pack of linkgit:git-fetch-pack[1].
1593
1594remote.<name>.tagopt::
1595        Setting this value to \--no-tags disables automatic tag following when
1596        fetching from remote <name>. Setting it to \--tags will fetch every
1597        tag from remote <name>, even if they are not reachable from remote
1598        branch heads.
1599
1600remote.<name>.vcs::
1601        Setting this to a value <vcs> will cause git to interact with
1602        the remote with the git-remote-<vcs> helper.
1603
1604remotes.<group>::
1605        The list of remotes which are fetched by "git remote update
1606        <group>".  See linkgit:git-remote[1].
1607
1608repack.usedeltabaseoffset::
1609        By default, linkgit:git-repack[1] creates packs that use
1610        delta-base offset. If you need to share your repository with
1611        git older than version 1.4.4, either directly or via a dumb
1612        protocol such as http, then you need to set this option to
1613        "false" and repack. Access from old git versions over the
1614        native protocol are unaffected by this option.
1615
1616rerere.autoupdate::
1617        When set to true, `git-rerere` updates the index with the
1618        resulting contents after it cleanly resolves conflicts using
1619        previously recorded resolution.  Defaults to false.
1620
1621rerere.enabled::
1622        Activate recording of resolved conflicts, so that identical
1623        conflict hunks can be resolved automatically, should they
1624        be encountered again.  linkgit:git-rerere[1] command is by
1625        default enabled if you create `rr-cache` directory under
1626        `$GIT_DIR`, but can be disabled by setting this option to false.
1627
1628sendemail.identity::
1629        A configuration identity. When given, causes values in the
1630        'sendemail.<identity>' subsection to take precedence over
1631        values in the 'sendemail' section. The default identity is
1632        the value of 'sendemail.identity'.
1633
1634sendemail.smtpencryption::
1635        See linkgit:git-send-email[1] for description.  Note that this
1636        setting is not subject to the 'identity' mechanism.
1637
1638sendemail.smtpssl::
1639        Deprecated alias for 'sendemail.smtpencryption = ssl'.
1640
1641sendemail.<identity>.*::
1642        Identity-specific versions of the 'sendemail.*' parameters
1643        found below, taking precedence over those when the this
1644        identity is selected, through command-line or
1645        'sendemail.identity'.

1670sendemail.signedoffcc::
1671        Deprecated alias for 'sendemail.signedoffbycc'.
1672
1673showbranch.default::
1674        The default set of branches for linkgit:git-show-branch[1].
1675        See linkgit:git-show-branch[1].
1676
1677status.relativePaths::
1678        By default, linkgit:git-status[1] shows paths relative to the
1679        current directory. Setting this variable to `false` shows paths
1680        relative to the repository root (this was the default for git
1681        prior to v1.5.4).
1682
1683status.showUntrackedFiles::
1684        By default, linkgit:git-status[1] and linkgit:git-commit[1] show
1685        files which are not currently tracked by Git. Directories which
1686        contain only untracked files, are shown with the directory name
1687        only. Showing untracked files means that Git needs to lstat() all
1688        all the files in the whole repository, which might be slow on some
1689        systems. So, this variable controls how the commands displays
1690        the untracked files. Possible values are:
1691+
1692--
1693        - 'no'     - Show no untracked files
1694        - 'normal' - Shows untracked files and directories
1695        - 'all'    - Shows also individual files in untracked directories.
1696--
1697+
1698If this variable is not specified, it defaults to 'normal'.
1699This variable can be overridden with the -u|--untracked-files option
1700of linkgit:git-status[1] and linkgit:git-commit[1].
1701
1702status.submodulesummary::
1703        Defaults to false.
1704        If this is set to a non zero number or true (identical to -1 or an
1705        unlimited number), the submodule summary will be enabled and a
1706        summary of commits for modified submodules will be shown (see
1707        --summary-limit option of linkgit:git-submodule[1]).
1708
1709tar.umask::
1710        This variable can be used to restrict the permission bits of
1711        tar archive entries.  The default is 0002, which turns off the
1712        world write bit.  The special value "user" indicates that the
1713        archiving user's umask will be used instead.  See umask(2) and
1714        linkgit:git-archive[1].
1715
1716transfer.unpackLimit::
1717        When `fetch.unpackLimit` or `receive.unpackLimit` are
1718        not set, the value of this variable is used instead.
1719        The default value is 100.
1720
1721url.<base>.insteadOf::
1722        Any URL that starts with this value will be rewritten to
1723        start, instead, with <base>. In cases where some site serves a
1724        large number of repositories, and serves them with multiple
1725        access methods, and some users need to use different access
1726        methods, this feature allows people to specify any of the
1727        equivalent URLs and have git automatically rewrite the URL to
1728        the best alternative for the particular user, even for a
1729        never-before-seen repository on the site.  When more than one
1730        insteadOf strings match a given URL, the longest match is used.
1731
1732url.<base>.pushInsteadOf::
1733        Any URL that starts with this value will not be pushed to;
1734        instead, it will be rewritten to start with <base>, and the
1735        resulting URL will be pushed to. In cases where some site serves
1736        a large number of repositories, and serves them with multiple
1737        access methods, some of which do not allow push, this feature
1738        allows people to specify a pull-only URL and have git
1739        automatically use an appropriate URL to push, even for a
1740        never-before-seen repository on the site.  When more than one
1741        pushInsteadOf strings match a given URL, the longest match is
1742        used.  If a remote has an explicit pushurl, git will ignore this
1743        setting for that remote.
1744
1745user.email::
1746        Your email address to be recorded in any newly created commits.
1747        Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and
1748        'EMAIL' environment variables.  See linkgit:git-commit-tree[1].
1749
1750user.name::
1751        Your full name to be recorded in any newly created commits.
1752        Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
1753        environment variables.  See linkgit:git-commit-tree[1].
1754
1755user.signingkey::
1756        If linkgit:git-tag[1] is not selecting the key you want it to
1757        automatically when creating a signed tag, you can override the
1758        default selection with this variable.  This option is passed
1759        unchanged to gpg's --local-user parameter, so you may specify a key
1760        using any method that gpg supports.
1761
1762web.browser::
1763        Specify a web browser that may be used by some commands.
1764        Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
1765        may use it.
