Documentation / config.txton commit doc: clarify --no-track option (70e9664)
   1CONFIGURATION FILE
   2------------------
   3
   4The git configuration file contains a number of variables that affect
   5the git command's behavior. `.git/config` file for each repository
   6is used to store the information for that repository, and
   7`$HOME/.gitconfig` is used to store per user information to give
   8fallback values for `.git/config` file. The file `/etc/gitconfig`
   9can be used to store system-wide defaults.
  10
  11They can be used by both the git plumbing
  12and the porcelains. The variables are divided into sections, where
  13in the fully qualified variable name 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 section
  30header before 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 example below:
  35
  36--------
  37        [section "subsection"]
  38
  39--------
  40
  41Subsection names can contain any characters except newline (doublequote
  42`"` and backslash have to be escaped as `\"` and `\\`,
  43respectively) and are case sensitive.  Section header 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 (case insensitive) alternative `[section.subsection]` syntax.
  49In this syntax subsection names follow the same restrictions as for section
  50name.
  51
  52All the other lines are recognized as setting variables, in the form
  53'name = value'.  If there is no equal sign on the line, the entire line
  54is taken as 'name' and the variable is recognized as boolean "true".
  55The variable names are case-insensitive and only alphanumeric
  56characters and `-` are allowed.  There can be more than one value
  57for a given variable; we say then that variable is multivalued.
  58
  59Leading and trailing whitespace in a variable value is discarded.
  60Internal whitespace within a variable value is retained verbatim.
  61
  62The values following the equals sign in variable assign are all either
  63a string, an integer, or a boolean.  Boolean values may be given as yes/no,
  640/1 or true/false.  Case is not significant in boolean values, when
  65converting value to the canonical form using '--bool' type specifier;
  66'git-config' will ensure that the output is "true" or "false".
  67
  68String values may be entirely or partially enclosed in double quotes.
  69You need to enclose variable value in double quotes if you want to
  70preserve leading or trailing whitespace, or if variable value contains
  71beginning of comment characters (if it contains '#' or ';').
  72Double quote `"` and backslash `\` characters in variable value must
  73be escaped: use `\"` for `"` and `\\` for `\`.
  74
  75The following escape sequences (beside `\"` and `\\`) are recognized:
  76`\n` for newline character (NL), `\t` for horizontal tabulation (HT, TAB)
  77and `\b` for backspace (BS).  No other char escape sequence, nor octal
  78char sequences are valid.
  79
  80Variable value ending in a `\` is continued on the next line in the
  81customary UNIX fashion.
  82
  83Some variables may require special value format.

 107Variables
 108~~~~~~~~~
 109
 110Note that this list is non-comprehensive and not necessarily complete.
 111For command-specific variables, you will find a more detailed description
 112in the appropriate manual page. You will find a description of non-core
 113porcelain configuration variables in the respective porcelain documentation.
 114
 115core.fileMode::
 116        If false, the executable bit differences between the index and
 117        the working copy are ignored; useful on broken filesystems like FAT.
 118        See linkgit:git-update-index[1]. True by default.
 119
 120core.ignoreCygwinFSTricks::
 121        This option is only used by Cygwin implementation of Git. If false,
 122        the Cygwin stat() and lstat() functions are used. This may be useful
 123        if your repository consists of a few separate directories joined in
 124        one hierarchy using Cygwin mount. If true, Git uses native Win32 API
 125        whenever it is possible and falls back to Cygwin functions only to
 126        handle symbol links. The native mode is more than twice faster than
 127        normal Cygwin l/stat() functions. True by default, unless core.filemode
 128        is true, in which case ignoreCygwinFSTricks is ignored as Cygwin's
 129        POSIX emulation is required to support core.filemode.
 130
 131core.trustctime::
 132        If false, the ctime differences between the index and the
 133        working copy are ignored; useful when the inode change time
 134        is regularly modified by something outside Git (file system
 135        crawlers and some backup systems).
 136        See linkgit:git-update-index[1]. True by default.
 137
 138core.quotepath::
 139        The commands that output paths (e.g. 'ls-files',
 140        'diff'), when not given the `-z` option, will quote
 141        "unusual" characters in the pathname by enclosing the
 142        pathname in a double-quote pair and with backslashes the
 143        same way strings in C source code are quoted.  If this
 144        variable is set to false, the bytes higher than 0x80 are
 145        not quoted but output as verbatim.  Note that double
 146        quote, backslash and control characters are always
 147        quoted without `-z` regardless of the setting of this
 148        variable.
 149
 150core.autocrlf::
 151        If true, makes git convert `CRLF` at the end of lines in text files to
 152        `LF` when reading from the filesystem, and convert in reverse when
 153        writing to the filesystem.  The variable can be set to
 154        'input', in which case the conversion happens only while
 155        reading from the filesystem but files are written out with
 156        `LF` at the end of lines.  Currently, which paths to consider
 157        "text" (i.e. be subjected to the autocrlf mechanism) is
 158        decided purely based on the contents.
 159
 160core.safecrlf::
 161        If true, makes git check if converting `CRLF` as controlled by
 162        `core.autocrlf` is reversible.  Git will verify if a command
 163        modifies a file in the work tree either directly or indirectly.
 164        For example, committing a file followed by checking out the
 165        same file should yield the original file in the work tree.  If
 166        this is not the case for the current setting of
 167        `core.autocrlf`, git will reject the file.  The variable can
 168        be set to "warn", in which case git will only warn about an
 169        irreversible conversion but continue the operation.
 170+
 171CRLF conversion bears a slight chance of corrupting data.
 172autocrlf=true will convert CRLF to LF during commit and LF to
 173CRLF during checkout.  A file that contains a mixture of LF and
 174CRLF before the commit cannot be recreated by git.  For text
 175files this is the right thing to do: it corrects line endings
 176such that we have only LF line endings in the repository.
 177But for binary files that are accidentally classified as text the
 178conversion can corrupt data.
 179+
 180If you recognize such corruption early you can easily fix it by
 181setting the conversion type explicitly in .gitattributes.  Right
 182after committing you still have the original file in your work
 183tree and this file is not yet corrupted.  You can explicitly tell
 184git that this file is binary and git will handle the file
 185appropriately.
 186+
 187Unfortunately, the desired effect of cleaning up text files with
 188mixed line endings and the undesired effect of corrupting binary
 189files cannot be distinguished.  In both cases CRLFs are removed
 190in an irreversible way.  For text files this is the right thing
 191to do because CRLFs are line endings, while for binary files
 192converting CRLFs corrupts data.
 193+
 194Note, this safety check does not mean that a checkout will generate a
 195file identical to the original file for a different setting of
 196`core.autocrlf`, but only for the current one.  For example, a text
 197file with `LF` would be accepted with `core.autocrlf=input` and could
 198later be checked out with `core.autocrlf=true`, in which case the
 199resulting file would contain `CRLF`, although the original file
 200contained `LF`.  However, in both work trees the line endings would be
 201consistent, that is either all `LF` or all `CRLF`, but never mixed.  A
 202file with mixed line endings would be reported by the `core.safecrlf`
 203mechanism.
 204
 205core.symlinks::
 206        If false, symbolic links are checked out as small plain files that
 207        contain the link text. linkgit:git-update-index[1] and
 208        linkgit:git-add[1] will not change the recorded type to regular
 209        file. Useful on filesystems like FAT that do not support
 210        symbolic links. True by default.
 211
 212core.gitProxy::
 213        A "proxy command" to execute (as 'command host port') instead
 214        of establishing direct connection to the remote server when
 215        using the git protocol for fetching. If the variable value is
 216        in the "COMMAND for DOMAIN" format, the command is applied only
 217        on hostnames ending with the specified domain string. This variable
 218        may be set multiple times and is matched in the given order;
 219        the first match wins.
 220+
 221Can be overridden by the 'GIT_PROXY_COMMAND' environment variable
 222(which always applies universally, without the special "for"
 223handling).
 224+
 225The special string `none` can be used as the proxy command to
 226specify that no proxy be used for a given domain pattern.
 227This is useful for excluding servers inside a firewall from
 228proxy use, while defaulting to a common proxy for external domains.
 229
 230core.ignoreStat::
 231        If true, commands which modify both the working tree and the index
 232        will mark the updated paths with the "assume unchanged" bit in the
 233        index. These marked files are then assumed to stay unchanged in the
 234        working copy, until you mark them otherwise manually - Git will not
 235        detect the file changes by lstat() calls. This is useful on systems
 236        where those are very slow, such as Microsoft Windows.
 237        See linkgit:git-update-index[1].
 238        False by default.
 239
 240core.preferSymlinkRefs::
 241        Instead of the default "symref" format for HEAD
 242        and other symbolic reference files, use symbolic links.
 243        This is sometimes needed to work with old scripts that
 244        expect HEAD to be a symbolic link.
 245
 246core.bare::
 247        If true this repository is assumed to be 'bare' and has no
 248        working directory associated with it.  If this is the case a
 249        number of commands that require a working directory will be
 250        disabled, such as linkgit:git-add[1] or linkgit:git-merge[1].
 251+
 252This setting is automatically guessed by linkgit:git-clone[1] or
 253linkgit:git-init[1] when the repository was created.  By default a
 254repository that ends in "/.git" is assumed to be not bare (bare =
 255false), while all other repositories are assumed to be bare (bare
 256= true).
 257
 258core.worktree::
 259        Set the path to the working tree.  The value will not be
 260        used in combination with repositories found automatically in
 261        a .git directory (i.e. $GIT_DIR is not set).
 262        This can be overridden by the GIT_WORK_TREE environment
 263        variable and the '--work-tree' command line option. It can be
 264        a absolute path or relative path to the directory specified by
 265        --git-dir or GIT_DIR.
 266        Note: If --git-dir or GIT_DIR are specified but none of
 267        --work-tree, GIT_WORK_TREE and core.worktree is specified,
 268        the current working directory is regarded as the top directory
 269        of your working tree.
 270
 271core.logAllRefUpdates::
 272        Enable the reflog. Updates to a ref <ref> is logged to the file
 273        "$GIT_DIR/logs/<ref>", by appending the new and old
 274        SHA1, the date/time and the reason of the update, but
 275        only when the file exists.  If this configuration
 276        variable is set to true, missing "$GIT_DIR/logs/<ref>"
 277        file is automatically created for branch heads.
 278+
 279This information can be used to determine what commit
 280was the tip of a branch "2 days ago".
 281+
 282This value is true by default in a repository that has
 283a working directory associated with it, and false by
 284default in a bare repository.
 285
 286core.repositoryFormatVersion::
 287        Internal variable identifying the repository format and layout
 288        version.
 289
 290core.sharedRepository::
 291        When 'group' (or 'true'), the repository is made shareable between
 292        several users in a group (making sure all the files and objects are
 293        group-writable). When 'all' (or 'world' or 'everybody'), the
 294        repository will be readable by all users, additionally to being
 295        group-shareable. When 'umask' (or 'false'), git will use permissions
 296        reported by umask(2). When '0xxx', where '0xxx' is an octal number,
 297        files in the repository will have this mode value. '0xxx' will override
 298        user's umask value, and thus, users with a safe umask (0077) can use
 299        this option. Examples: '0660' is equivalent to 'group'. '0640' is a
 300        repository that is group-readable but not group-writable.
 301        See linkgit:git-init[1]. False by default.
 302
 303core.warnAmbiguousRefs::
 304        If true, git will warn you if the ref name you passed it is ambiguous
 305        and might match multiple refs in the .git/refs/ tree. True by default.
 306
 307core.compression::
 308        An integer -1..9, indicating a default compression level.
 309        -1 is the zlib default. 0 means no compression,
 310        and 1..9 are various speed/size tradeoffs, 9 being slowest.
 311        If set, this provides a default to other compression variables,
 312        such as 'core.loosecompression' and 'pack.compression'.
 313
 314core.loosecompression::
 315        An integer -1..9, indicating the compression level for objects that
 316        are not in a pack file. -1 is the zlib default. 0 means no
 317        compression, and 1..9 are various speed/size tradeoffs, 9 being
 318        slowest.  If not set,  defaults to core.compression.  If that is
 319        not set,  defaults to 1 (best speed).
 320
 321core.packedGitWindowSize::
 322        Number of bytes of a pack file to map into memory in a
 323        single mapping operation.  Larger window sizes may allow
 324        your system to process a smaller number of large pack files
 325        more quickly.  Smaller window sizes will negatively affect
 326        performance due to increased calls to the operating system's
 327        memory manager, but may improve performance when accessing
 328        a large number of large pack files.
 329+
 330Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
 331MiB on 32 bit platforms and 1 GiB on 64 bit platforms.  This should
 332be reasonable for all users/operating systems.  You probably do
 333not need to adjust this value.
 334+
 335Common unit suffixes of 'k', 'm', or 'g' are supported.
 336
 337core.packedGitLimit::
 338        Maximum number of bytes to map simultaneously into memory
 339        from pack files.  If Git needs to access more than this many
 340        bytes at once to complete an operation it will unmap existing
 341        regions to reclaim virtual address space within the process.
 342+
 343Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms.
 344This should be reasonable for all users/operating systems, except on
 345the largest projects.  You probably do not need to adjust this value.
 346+
 347Common unit suffixes of 'k', 'm', or 'g' are supported.
 348
 349core.deltaBaseCacheLimit::
 350        Maximum number of bytes to reserve for caching base objects
 351        that multiple deltafied objects reference.  By storing the
 352        entire decompressed base objects in a cache Git is able
 353        to avoid unpacking and decompressing frequently used base
 354        objects multiple times.
 355+
 356Default is 16 MiB on all platforms.  This should be reasonable
 357for all users/operating systems, except on the largest projects.
 358You probably do not need to adjust this value.
 359+
 360Common unit suffixes of 'k', 'm', or 'g' are supported.
 361
 362core.excludesfile::
 363        In addition to '.gitignore' (per-directory) and
 364        '.git/info/exclude', git looks into this file for patterns
 365        of files which are not meant to be tracked.  See
 366        linkgit:gitignore[5].
 367
 368core.editor::
 369        Commands such as `commit` and `tag` that lets you edit
 370        messages by launching an editor uses the value of this
 371        variable when it is set, and the environment variable
 372        `GIT_EDITOR` is not set.  The order of preference is
 373        `GIT_EDITOR` environment, `core.editor`, `VISUAL` and
 374        `EDITOR` environment variables and then finally `vi`.
 375
 376core.pager::
 377        The command that git will use to paginate output.  Can
 378        be overridden with the `GIT_PAGER` environment
 379        variable.  Note that git sets the `LESS` environment
 380        variable to `FRSX` if it is unset when it runs the
 381        pager.  One can change these settings by setting the
 382        `LESS` variable to some other value.  Alternately,
 383        these settings can be overridden on a project or
 384        global basis by setting the `core.pager` option.
 385        Setting `core.pager` has no affect on the `LESS`
 386        environment variable behaviour above, so if you want
 387        to override git's default settings this way, you need
 388        to be explicit.  For example, to disable the S option
 389        in a backward compatible manner, set `core.pager`
 390        to `less -+$LESS -FRX`.  This will be passed to the
 391        shell by git, which will translate the final command to
 392        `LESS=FRSX less -+FRSX -FRX`.
 393
 394core.whitespace::
 395        A comma separated list of common whitespace problems to
 396        notice.  'git-diff' will use `color.diff.whitespace` to
 397        highlight them, and 'git-apply --whitespace=error' will
 398        consider them as errors.  You can prefix `-` to disable
 399        any of them (e.g. `-trailing-space`):
 400+
 401* `trailing-space` treats trailing whitespaces at the end of the line
 402  as an error (enabled by default).
 403* `space-before-tab` treats a space character that appears immediately
 404  before a tab character in the initial indent part of the line as an
 405  error (enabled by default).
 406* `indent-with-non-tab` treats a line that is indented with 8 or more
 407  space characters as an error (not enabled by default).
 408* `cr-at-eol` treats a carriage-return at the end of line as
 409  part of the line terminator, i.e. with it, `trailing-space`
 410  does not trigger if the character before such a carriage-return
 411  is not a whitespace (not enabled by default).
 412
 413core.fsyncobjectfiles::
 414        This boolean will enable 'fsync()' when writing object files.
 415+
 416This is a total waste of time and effort on a filesystem that orders
 417data writes properly, but can be useful for filesystems that do not use
 418journalling (traditional UNIX filesystems) or that only journal metadata
 419and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback").
 420
 421core.preloadindex::
 422        Enable parallel index preload for operations like 'git diff'
 423+
 424This can speed up operations like 'git diff' and 'git status' especially
 425on filesystems like NFS that have weak caching semantics and thus
 426relatively high IO latencies.  With this set to 'true', git will do the
 427index comparison to the filesystem data in parallel, allowing
 428overlapping IO's.
 429
 430alias.*::
 431        Command aliases for the linkgit:git[1] command wrapper - e.g.
 432        after defining "alias.last = cat-file commit HEAD", the invocation
 433        "git last" is equivalent to "git cat-file commit HEAD". To avoid
 434        confusion and troubles with script usage, aliases that
 435        hide existing git commands are ignored. Arguments are split by
 436        spaces, the usual shell quoting and escaping is supported.
 437        quote pair and a backslash can be used to quote them.
 438+
 439If the alias expansion is prefixed with an exclamation point,
 440it will be treated as a shell command.  For example, defining
 441"alias.new = !gitk --all --not ORIG_HEAD", the invocation
 442"git new" is equivalent to running the shell command
 443"gitk --all --not ORIG_HEAD".
 444
 445apply.whitespace::
 446        Tells 'git-apply' how to handle whitespaces, in the same way
 447        as the '--whitespace' option. See linkgit:git-apply[1].
 448
 449branch.autosetupmerge::
 450        Tells 'git-branch' and 'git-checkout' to setup new branches
 451        so that linkgit:git-pull[1] will appropriately merge from the
 452        starting point branch. Note that even if this option is not set,
 453        this behavior can be chosen per-branch using the `--track`
 454        and `--no-track` options. The valid settings are: `false` -- no
 455        automatic setup is done; `true` -- automatic setup is done when the
 456        starting point is a remote branch; `always` -- automatic setup is
 457        done when the starting point is either a local branch or remote
 458        branch. This option defaults to true.
 459
 460branch.autosetuprebase::
 461        When a new branch is created with 'git-branch' or 'git-checkout'
 462        that tracks another branch, this variable tells git to set
 463        up pull to rebase instead of merge (see "branch.<name>.rebase").
 464        When `never`, rebase is never automatically set to true.
 465        When `local`, rebase is set to true for tracked branches of
 466        other local branches.
 467        When `remote`, rebase is set to true for tracked branches of
 468        remote branches.
 469        When `always`, rebase will be set to true for all tracking
 470        branches.
 471        See "branch.autosetupmerge" for details on how to set up a
 472        branch to track another branch.
 473        This option defaults to never.
 474
 475branch.<name>.remote::
 476        When in branch <name>, it tells 'git-fetch' and 'git-push' which
 477        remote to fetch from/push to.  It defaults to `origin` if no remote is
 478        configured. `origin` is also used if you are not on any branch.
 479
 480branch.<name>.merge::
 481        Defines, together with branch.<name>.remote, the upstream branch
 482        for the given branch. It tells 'git-fetch'/'git-pull' which
 483        branch to merge and can also affect 'git-push' (see push.default).
 484        When in branch <name>, it tells 'git-fetch' the default
 485        refspec to be marked for merging in FETCH_HEAD. The value is
 486        handled like the remote part of a refspec, and must match a
 487        ref which is fetched from the remote given by
 488        "branch.<name>.remote".
 489        The merge information is used by 'git-pull' (which at first calls
 490        'git-fetch') to lookup the default branch for merging. Without
 491        this option, 'git-pull' defaults to merge the first refspec fetched.
 492        Specify multiple values to get an octopus merge.
 493        If you wish to setup 'git-pull' so that it merges into <name> from
 494        another branch in the local repository, you can point
 495        branch.<name>.merge to the desired branch, and use the special setting
 496        `.` (a period) for branch.<name>.remote.
 497
 498branch.<name>.mergeoptions::
 499        Sets default options for merging into branch <name>. The syntax and
 500        supported options are equal to that of linkgit:git-merge[1], but
 501        option values containing whitespace characters are currently not
 502        supported.
 503
 504branch.<name>.rebase::
 505        When true, rebase the branch <name> on top of the fetched branch,
 506        instead of merging the default branch from the default remote when
 507        "git pull" is run.
 508        *NOTE*: this is a possibly dangerous operation; do *not* use
 509        it unless you understand the implications (see linkgit:git-rebase[1]
 510        for details).
 511
 512browser.<tool>.cmd::
 513        Specify the command to invoke the specified browser. The
 514        specified command is evaluated in shell with the URLs passed
 515        as arguments. (See linkgit:git-web--browse[1].)
 516
 517browser.<tool>.path::
 518        Override the path for the given tool that may be used to
 519        browse HTML help (see '-w' option in linkgit:git-help[1]) or a
 520        working repository in gitweb (see linkgit:git-instaweb[1]).
 521
 522clean.requireForce::
 523        A boolean to make git-clean do nothing unless given -f
 524        or -n.   Defaults to true.
 525
 526color.branch::
 527        A boolean to enable/disable color in the output of
 528        linkgit:git-branch[1]. May be set to `always`,
 529        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 530        only when the output is to a terminal. Defaults to false.
 531
 532color.branch.<slot>::
 533        Use customized color for branch coloration. `<slot>` is one of
 534        `current` (the current branch), `local` (a local branch),
 535        `remote` (a tracking branch in refs/remotes/), `plain` (other
 536        refs).
 537+
 538The value for these configuration variables is a list of colors (at most
 539two) and attributes (at most one), separated by spaces.  The colors
 540accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`,
 541`magenta`, `cyan` and `white`; the attributes are `bold`, `dim`, `ul`,
 542`blink` and `reverse`.  The first color given is the foreground; the
 543second is the background.  The position of the attribute, if any,
 544doesn't matter.
 545
 546color.diff::
 547        When set to `always`, always use colors in patch.
 548        When false (or `never`), never.  When set to `true` or `auto`, use
 549        colors only when the output is to the terminal. Defaults to false.
 550
 551color.diff.<slot>::
 552        Use customized color for diff colorization.  `<slot>` specifies
 553        which part of the patch to use the specified color, and is one
 554        of `plain` (context text), `meta` (metainformation), `frag`
 555        (hunk header), `old` (removed lines), `new` (added lines),
 556        `commit` (commit headers), or `whitespace` (highlighting
 557        whitespace errors). The values of these variables may be specified as
 558        in color.branch.<slot>.
 559
 560color.grep::
 561        When set to `always`, always highlight matches.  When `false` (or
 562        `never`), never.  When set to `true` or `auto`, use color only
 563        when the output is written to the terminal.  Defaults to `false`.
 564
 565color.grep.external::
 566        The string value of this variable is passed to an external 'grep'
 567        command as a command line option if match highlighting is turned
 568        on.  If set to an empty string, no option is passed at all,
 569        turning off coloring for external 'grep' calls; this is the default.
 570        For GNU grep, set it to `--color=always` to highlight matches even
 571        when a pager is used.
 572
 573color.grep.match::
 574        Use customized color for matches.  The value of this variable
 575        may be specified as in color.branch.<slot>.  It is passed using
 576        the environment variables 'GREP_COLOR' and 'GREP_COLORS' when
 577        calling an external 'grep'.
 578
 579color.interactive::
 580        When set to `always`, always use colors for interactive prompts
 581        and displays (such as those used by "git-add --interactive").
 582        When false (or `never`), never.  When set to `true` or `auto`, use
 583        colors only when the output is to the terminal. Defaults to false.
 584
 585color.interactive.<slot>::
 586        Use customized color for 'git-add --interactive'
 587        output. `<slot>` may be `prompt`, `header`, `help` or `error`, for
 588        four distinct types of normal output from interactive
 589        programs.  The values of these variables may be specified as
 590        in color.branch.<slot>.
 591
 592color.pager::
 593        A boolean to enable/disable colored output when the pager is in
 594        use (default is true).
 595
 596color.status::
 597        A boolean to enable/disable color in the output of
 598        linkgit:git-status[1]. May be set to `always`,
 599        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 600        only when the output is to a terminal. Defaults to false.
 601
 602color.status.<slot>::
 603        Use customized color for status colorization. `<slot>` is
 604        one of `header` (the header text of the status message),
 605        `added` or `updated` (files which are added but not committed),
 606        `changed` (files which are changed but not added in the index),
 607        `untracked` (files which are not tracked by git), or
 608        `nobranch` (the color the 'no branch' warning is shown in, defaulting
 609        to red). The values of these variables may be specified as in
 610        color.branch.<slot>.
 611
 612color.ui::
 613        When set to `always`, always use colors in all git commands which
 614        are capable of colored output. When false (or `never`), never. When
 615        set to `true` or `auto`, use colors only when the output is to the
 616        terminal. When more specific variables of color.* are set, they always
 617        take precedence over this setting. Defaults to false.
 618
 619commit.template::
 620        Specify a file to use as the template for new commit messages.
 621
 622diff.autorefreshindex::
 623        When using 'git-diff' to compare with work tree
 624        files, do not consider stat-only change as changed.
 625        Instead, silently run `git update-index --refresh` to
 626        update the cached stat information for paths whose
 627        contents in the work tree match the contents in the
 628        index.  This option defaults to true.  Note that this
 629        affects only 'git-diff' Porcelain, and not lower level
 630        'diff' commands, such as 'git-diff-files'.
 631
 632diff.external::
 633        If this config variable is set, diff generation is not
 634        performed using the internal diff machinery, but using the
 635        given command.  Can be overridden with the `GIT_EXTERNAL_DIFF'
 636        environment variable.  The command is called with parameters
 637        as described under "git Diffs" in linkgit:git[1].  Note: if
 638        you want to use an external diff program only on a subset of
 639        your files, you might want to use linkgit:gitattributes[5] instead.
 640
 641diff.mnemonicprefix::
 642        If set, 'git-diff' uses a prefix pair that is different from the
 643        standard "a/" and "b/" depending on what is being compared.  When
 644        this configuration is in effect, reverse diff output also swaps
 645        the order of the prefixes:
 646'git-diff';;
 647        compares the (i)ndex and the (w)ork tree;
 648'git-diff HEAD';;
 649         compares a (c)ommit and the (w)ork tree;
 650'git diff --cached';;
 651        compares a (c)ommit and the (i)ndex;
 652'git-diff HEAD:file1 file2';;
 653        compares an (o)bject and a (w)ork tree entity;
 654'git diff --no-index a b';;
 655        compares two non-git things (1) and (2).
 656
 657diff.renameLimit::
 658        The number of files to consider when performing the copy/rename
 659        detection; equivalent to the 'git-diff' option '-l'.
 660
 661diff.renames::
 662        Tells git to detect renames.  If set to any boolean value, it
 663        will enable basic rename detection.  If set to "copies" or
 664        "copy", it will detect copies, as well.
 665
 666diff.suppressBlankEmpty::
 667        A boolean to inhibit the standard behavior of printing a space
 668        before each empty output line. Defaults to false.
 669
 670diff.wordRegex::
 671        A POSIX Extended Regular Expression used to determine what is a "word"
 672        when performing word-by-word difference calculations.  Character
 673        sequences that match the regular expression are "words", all other
 674        characters are *ignorable* whitespace.
 675
 676fetch.unpackLimit::
 677        If the number of objects fetched over the git native
 678        transfer is below this
 679        limit, then the objects will be unpacked into loose object
 680        files. However if the number of received objects equals or
 681        exceeds this limit then the received pack will be stored as
 682        a pack, after adding any missing delta bases.  Storing the
 683        pack from a push can make the push operation complete faster,
 684        especially on slow filesystems.  If not set, the value of
 685        `transfer.unpackLimit` is used instead.
 686
 687format.numbered::
 688        A boolean which can enable or disable sequence numbers in patch
 689        subjects.  It defaults to "auto" which enables it only if there
 690        is more than one patch.  It can be enabled or disabled for all
 691        messages by setting it to "true" or "false".  See --numbered
 692        option in linkgit:git-format-patch[1].
 693
 694format.headers::
 695        Additional email headers to include in a patch to be submitted
 696        by mail.  See linkgit:git-format-patch[1].
 697
 698format.suffix::
 699        The default for format-patch is to output files with the suffix
 700        `.patch`. Use this variable to change that suffix (make sure to
 701        include the dot if you want it).
 702
 703format.pretty::
 704        The default pretty format for log/show/whatchanged command,
 705        See linkgit:git-log[1], linkgit:git-show[1],
 706        linkgit:git-whatchanged[1].
 707
 708format.thread::
 709        The default threading style for 'git-format-patch'.  Can be
 710        either a boolean value, `shallow` or `deep`.  'Shallow'
 711        threading makes every mail a reply to the head of the series,
 712        where the head is chosen from the cover letter, the
 713        `\--in-reply-to`, and the first patch mail, in this order.
 714        'Deep' threading makes every mail a reply to the previous one.
 715        A true boolean value is the same as `shallow`, and a false
 716        value disables threading.
 717
 718format.signoff::
 719    A boolean value which lets you enable the `-s/--signoff` option of
 720    format-patch by default. *Note:* Adding the Signed-off-by: line to a
 721    patch should be a conscious act and means that you certify you have
 722    the rights to submit this work under the same open source license.
 723    Please see the 'SubmittingPatches' document for further discussion.
 724
 725gc.aggressiveWindow::
 726        The window size parameter used in the delta compression
 727        algorithm used by 'git-gc --aggressive'.  This defaults
 728        to 10.
 729
 730gc.auto::
 731        When there are approximately more than this many loose
 732        objects in the repository, `git gc --auto` will pack them.
 733        Some Porcelain commands use this command to perform a
 734        light-weight garbage collection from time to time.  The
 735        default value is 6700.  Setting this to 0 disables it.
 736
 737gc.autopacklimit::
 738        When there are more than this many packs that are not
 739        marked with `*.keep` file in the repository, `git gc
 740        --auto` consolidates them into one larger pack.  The
 741        default value is 50.  Setting this to 0 disables it.
 742
 743gc.packrefs::
 744        'git-gc' does not run `git pack-refs` in a bare repository by
 745        default so that older dumb-transport clients can still fetch
 746        from the repository.  Setting this to `true` lets 'git-gc'
 747        to run `git pack-refs`.  Setting this to `false` tells
 748        'git-gc' never to run `git pack-refs`. The default setting is
 749        `notbare`. Enable it only when you know you do not have to
 750        support such clients.  The default setting will change to `true`
 751        at some stage, and setting this to `false` will continue to
 752        prevent `git pack-refs` from being run from 'git-gc'.
 753
 754gc.pruneexpire::
 755        When 'git-gc' is run, it will call 'prune --expire 2.weeks.ago'.
 756        Override the grace period with this config variable.  The value
 757        "now" may be used to disable this  grace period and always prune
 758        unreachable objects immediately.
 759
 760gc.reflogexpire::
 761        'git-reflog expire' removes reflog entries older than
 762        this time; defaults to 90 days.
 763
 764gc.reflogexpireunreachable::
 765        'git-reflog expire' removes reflog entries older than
 766        this time and are not reachable from the current tip;
 767        defaults to 30 days.
 768
 769gc.rerereresolved::
 770        Records of conflicted merge you resolved earlier are
 771        kept for this many days when 'git-rerere gc' is run.
 772        The default is 60 days.  See linkgit:git-rerere[1].
 773
 774gc.rerereunresolved::
 775        Records of conflicted merge you have not resolved are
 776        kept for this many days when 'git-rerere gc' is run.
 777        The default is 15 days.  See linkgit:git-rerere[1].
 778
 779gitcvs.commitmsgannotation::
 780        Append this string to each commit message. Set to empty string
 781        to disable this feature. Defaults to "via git-CVS emulator".
 782
 783gitcvs.enabled::
 784        Whether the CVS server interface is enabled for this repository.
 785        See linkgit:git-cvsserver[1].
 786
 787gitcvs.logfile::
 788        Path to a log file where the CVS server interface well... logs
 789        various stuff. See linkgit:git-cvsserver[1].
 790
 791gitcvs.usecrlfattr::
 792        If true, the server will look up the `crlf` attribute for
 793        files to determine the '-k' modes to use. If `crlf` is set,
 794        the '-k' mode will be left blank, so cvs clients will
 795        treat it as text. If `crlf` is explicitly unset, the file
 796        will be set with '-kb' mode, which suppresses any newline munging
 797        the client might otherwise do. If `crlf` is not specified,
 798        then 'gitcvs.allbinary' is used. See linkgit:gitattributes[5].
 799
 800gitcvs.allbinary::
 801        This is used if 'gitcvs.usecrlfattr' does not resolve
 802        the correct '-kb' mode to use. If true, all
 803        unresolved files are sent to the client in
 804        mode '-kb'. This causes the client to treat them
 805        as binary files, which suppresses any newline munging it
 806        otherwise might do. Alternatively, if it is set to "guess",
 807        then the contents of the file are examined to decide if
 808        it is binary, similar to 'core.autocrlf'.
 809
 810gitcvs.dbname::
 811        Database used by git-cvsserver to cache revision information
 812        derived from the git repository. The exact meaning depends on the
 813        used database driver, for SQLite (which is the default driver) this
 814        is a filename. Supports variable substitution (see
 815        linkgit:git-cvsserver[1] for details). May not contain semicolons (`;`).
 816        Default: '%Ggitcvs.%m.sqlite'
 817
 818gitcvs.dbdriver::
 819        Used Perl DBI driver. You can specify any available driver
 820        for this here, but it might not work. git-cvsserver is tested
 821        with 'DBD::SQLite', reported to work with 'DBD::Pg', and
 822        reported *not* to work with 'DBD::mysql'. Experimental feature.
 823        May not contain double colons (`:`). Default: 'SQLite'.
 824        See linkgit:git-cvsserver[1].
 825
 826gitcvs.dbuser, gitcvs.dbpass::
 827        Database user and password. Only useful if setting 'gitcvs.dbdriver',
 828        since SQLite has no concept of database users and/or passwords.
 829        'gitcvs.dbuser' supports variable substitution (see
 830        linkgit:git-cvsserver[1] for details).
 831
 832gitcvs.dbTableNamePrefix::
 833        Database table name prefix.  Prepended to the names of any
 834        database tables used, allowing a single database to be used
 835        for several repositories.  Supports variable substitution (see
 836        linkgit:git-cvsserver[1] for details).  Any non-alphabetic
 837        characters will be replaced with underscores.
 838
 839All gitcvs variables except for 'gitcvs.usecrlfattr' and
 840'gitcvs.allbinary' can also be specified as
 841'gitcvs.<access_method>.<varname>' (where 'access_method'
 842is one of "ext" and "pserver") to make them apply only for the given
 843access method.
 844
 845gui.commitmsgwidth::
 846        Defines how wide the commit message window is in the
 847        linkgit:git-gui[1]. "75" is the default.
 848
 849gui.diffcontext::
 850        Specifies how many context lines should be used in calls to diff
 851        made by the linkgit:git-gui[1]. The default is "5".
 852
 853gui.encoding::
 854        Specifies the default encoding to use for displaying of
 855        file contents in linkgit:git-gui[1] and linkgit:gitk[1].
 856        It can be overridden by setting the 'encoding' attribute
 857        for relevant files (see linkgit:gitattributes[5]).
 858        If this option is not set, the tools default to the
 859        locale encoding.
 860
 861gui.matchtrackingbranch::
 862        Determines if new branches created with linkgit:git-gui[1] should
 863        default to tracking remote branches with matching names or
 864        not. Default: "false".
 865
 866gui.newbranchtemplate::
 867        Is used as suggested name when creating new branches using the
 868        linkgit:git-gui[1].
 869
 870gui.pruneduringfetch::
 871        "true" if linkgit:git-gui[1] should prune tracking branches when
 872        performing a fetch. The default value is "false".
 873
 874gui.trustmtime::
 875        Determines if linkgit:git-gui[1] should trust the file modification
 876        timestamp or not. By default the timestamps are not trusted.
 877
 878gui.spellingdictionary::
 879        Specifies the dictionary used for spell checking commit messages in
 880        the linkgit:git-gui[1]. When set to "none" spell checking is turned
 881        off.
 882
 883gui.fastcopyblame::
 884        If true, 'git gui blame' uses '-C' instead of '-C -C' for original
 885        location detection. It makes blame significantly faster on huge
 886        repositories at the expense of less thorough copy detection.
 887
 888gui.copyblamethreshold::
 889        Specifies the threshold to use in 'git gui blame' original location
 890        detection, measured in alphanumeric characters. See the
 891        linkgit:git-blame[1] manual for more information on copy detection.
 892
 893gui.blamehistoryctx::
 894        Specifies the radius of history context in days to show in
 895        linkgit:gitk[1] for the selected commit, when the `Show History
 896        Context` menu item is invoked from 'git gui blame'. If this
 897        variable is set to zero, the whole history is shown.
 898
 899guitool.<name>.cmd::
 900        Specifies the shell command line to execute when the corresponding item
 901        of the linkgit:git-gui[1] `Tools` menu is invoked. This option is
 902        mandatory for every tool. The command is executed from the root of
 903        the working directory, and in the environment it receives the name of
 904        the tool as 'GIT_GUITOOL', the name of the currently selected file as
 905        'FILENAME', and the name of the current branch as 'CUR_BRANCH' (if
 906        the head is detached, 'CUR_BRANCH' is empty).
 907
 908guitool.<name>.needsfile::
 909        Run the tool only if a diff is selected in the GUI. It guarantees
 910        that 'FILENAME' is not empty.
 911
 912guitool.<name>.noconsole::
 913        Run the command silently, without creating a window to display its
 914        output.
 915
 916guitool.<name>.norescan::
 917        Don't rescan the working directory for changes after the tool
 918        finishes execution.
 919
 920guitool.<name>.confirm::
 921        Show a confirmation dialog before actually running the tool.
 922
 923guitool.<name>.argprompt::
 924        Request a string argument from the user, and pass it to the tool
 925        through the 'ARGS' environment variable. Since requesting an
 926        argument implies confirmation, the 'confirm' option has no effect
 927        if this is enabled. If the option is set to 'true', 'yes', or '1',
 928        the dialog uses a built-in generic prompt; otherwise the exact
 929        value of the variable is used.
 930
 931guitool.<name>.revprompt::
 932        Request a single valid revision from the user, and set the
 933        'REVISION' environment variable. In other aspects this option
 934        is similar to 'argprompt', and can be used together with it.
 935
 936guitool.<name>.revunmerged::
 937        Show only unmerged branches in the 'revprompt' subdialog.
 938        This is useful for tools similar to merge or rebase, but not
 939        for things like checkout or reset.
 940
 941guitool.<name>.title::
 942        Specifies the title to use for the prompt dialog. The default
 943        is the tool name.
 944
 945guitool.<name>.prompt::
 946        Specifies the general prompt string to display at the top of
 947        the dialog, before subsections for 'argprompt' and 'revprompt'.
 948        The default value includes the actual command.
 949
 950help.browser::
 951        Specify the browser that will be used to display help in the
 952        'web' format. See linkgit:git-help[1].
 953
 954help.format::
 955        Override the default help format used by linkgit:git-help[1].
 956        Values 'man', 'info', 'web' and 'html' are supported. 'man' is
 957        the default. 'web' and 'html' are the same.
 958
 959help.autocorrect::
 960        Automatically correct and execute mistyped commands after
 961        waiting for the given number of deciseconds (0.1 sec). If more
 962        than one command can be deduced from the entered text, nothing
 963        will be executed.  If the value of this option is negative,
 964        the corrected command will be executed immediately. If the
 965        value is 0 - the command will be just shown but not executed.
 966        This is the default.
 967
 968http.proxy::
 969        Override the HTTP proxy, normally configured using the 'http_proxy'
 970        environment variable (see linkgit:curl[1]).  This can be overridden
 971        on a per-remote basis; see remote.<name>.proxy
 972
 973http.sslVerify::
 974        Whether to verify the SSL certificate when fetching or pushing
 975        over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
 976        variable.
 977
 978http.sslCert::
 979        File containing the SSL certificate when fetching or pushing
 980        over HTTPS. Can be overridden by the 'GIT_SSL_CERT' environment
 981        variable.
 982
 983http.sslKey::
 984        File containing the SSL private key when fetching or pushing
 985        over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment
 986        variable.
 987
 988http.sslCAInfo::
 989        File containing the certificates to verify the peer with when
 990        fetching or pushing over HTTPS. Can be overridden by the
 991        'GIT_SSL_CAINFO' environment variable.
 992
 993http.sslCAPath::
 994        Path containing files with the CA certificates to verify the peer
 995        with when fetching or pushing over HTTPS. Can be overridden
 996        by the 'GIT_SSL_CAPATH' environment variable.
 997
 998http.maxRequests::
 999        How many HTTP requests to launch in parallel. Can be overridden
1000        by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5.
1001
1002http.lowSpeedLimit, http.lowSpeedTime::
1003        If the HTTP transfer speed is less than 'http.lowSpeedLimit'
1004        for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
1005        Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and
1006        'GIT_HTTP_LOW_SPEED_TIME' environment variables.
1007
1008http.noEPSV::
1009        A boolean which disables using of EPSV ftp command by curl.
1010        This can helpful with some "poor" ftp servers which don't
1011        support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
1012        environment variable. Default is false (curl will use EPSV).
1013
1014i18n.commitEncoding::
1015        Character encoding the commit messages are stored in; git itself
1016        does not care per se, but this information is necessary e.g. when
1017        importing commits from emails or in the gitk graphical history
1018        browser (and possibly at other places in the future or in other
1019        porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.
1020
1021i18n.logOutputEncoding::
1022        Character encoding the commit messages are converted to when
1023        running 'git-log' and friends.
1024
1025imap::
1026        The configuration variables in the 'imap' section are described
1027        in linkgit:git-imap-send[1].
1028
1029instaweb.browser::
1030        Specify the program that will be used to browse your working
1031        repository in gitweb. See linkgit:git-instaweb[1].
1032
1033instaweb.httpd::
1034        The HTTP daemon command-line to start gitweb on your working
1035        repository. See linkgit:git-instaweb[1].
1036
1037instaweb.local::
1038        If true the web server started by linkgit:git-instaweb[1] will
1039        be bound to the local IP (127.0.0.1).
1040
1041instaweb.modulepath::
1042        The module path for an apache httpd used by linkgit:git-instaweb[1].
1043
1044instaweb.port::
1045        The port number to bind the gitweb httpd to. See
1046        linkgit:git-instaweb[1].
1047
1048interactive.singlekey::
1049        In interactive programs, allow the user to provide one-letter
1050        input with a single key (i.e., without hitting enter).
1051        Currently this is used only by the `\--patch` mode of
1052        linkgit:git-add[1].  Note that this setting is silently
1053        ignored if portable keystroke input is not available.
1054
1055log.date::
1056        Set default date-time mode for the log command. Setting log.date
1057        value is similar to using 'git-log'\'s --date option. The value is one of the
1058        following alternatives: {relative,local,default,iso,rfc,short}.
1059        See linkgit:git-log[1].
1060
1061log.showroot::
1062        If true, the initial commit will be shown as a big creation event.
1063        This is equivalent to a diff against an empty tree.
1064        Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
1065        normally hide the root commit will now show it. True by default.
1066
1067mailmap.file::
1068        The location of an augmenting mailmap file. The default
1069        mailmap, located in the root of the repository, is loaded
1070        first, then the mailmap file pointed to by this variable.
1071        The location of the mailmap file may be in a repository
1072        subdirectory, or somewhere outside of the repository itself.
1073        See linkgit:git-shortlog[1] and linkgit:git-blame[1].
1074
1075man.viewer::
1076        Specify the programs that may be used to display help in the
1077        'man' format. See linkgit:git-help[1].
1078
1079man.<tool>.cmd::
1080        Specify the command to invoke the specified man viewer. The
1081        specified command is evaluated in shell with the man page
1082        passed as argument. (See linkgit:git-help[1].)
1083
1084man.<tool>.path::
1085        Override the path for the given tool that may be used to
1086        display help in the 'man' format. See linkgit:git-help[1].
1087
1088include::merge-config.txt[]
1089
1090mergetool.<tool>.path::
1091        Override the path for the given tool.  This is useful in case
1092        your tool is not in the PATH.
1093
1094mergetool.<tool>.cmd::
1095        Specify the command to invoke the specified merge tool.  The
1096        specified command is evaluated in shell with the following
1097        variables available: 'BASE' is the name of a temporary file
1098        containing the common base of the files to be merged, if available;
1099        'LOCAL' is the name of a temporary file containing the contents of
1100        the file on the current branch; 'REMOTE' is the name of a temporary
1101        file containing the contents of the file from the branch being
1102        merged; 'MERGED' contains the name of the file to which the merge
1103        tool should write the results of a successful merge.
1104
1105mergetool.<tool>.trustExitCode::
1106        For a custom merge command, specify whether the exit code of
1107        the merge command can be used to determine whether the merge was
1108        successful.  If this is not set to true then the merge target file
1109        timestamp is checked and the merge assumed to have been successful
1110        if the file has been updated, otherwise the user is prompted to
1111        indicate the success of the merge.
1112
1113mergetool.keepBackup::
1114        After performing a merge, the original file with conflict markers
1115        can be saved as a file with a `.orig` extension.  If this variable
1116        is set to `false` then this file is not preserved.  Defaults to
1117        `true` (i.e. keep the backup files).
1118
1119mergetool.keepTemporaries::
1120        When invoking a custom merge tool, git uses a set of temporary
1121        files to pass to the tool. If the tool returns an error and this
1122        variable is set to `true`, then these temporary files will be
1123        preserved, otherwise they will be removed after the tool has
1124        exited. Defaults to `false`.
1125
1126mergetool.prompt::
1127        Prompt before each invocation of the merge resolution program.
1128
1129pack.window::
1130        The size of the window used by linkgit:git-pack-objects[1] when no
1131        window size is given on the command line. Defaults to 10.
1132
1133pack.depth::
1134        The maximum delta depth used by linkgit:git-pack-objects[1] when no
1135        maximum depth is given on the command line. Defaults to 50.
1136
1137pack.windowMemory::
1138        The window memory size limit used by linkgit:git-pack-objects[1]
1139        when no limit is given on the command line.  The value can be
1140        suffixed with "k", "m", or "g".  Defaults to 0, meaning no
1141        limit.
1142
1143pack.compression::
1144        An integer -1..9, indicating the compression level for objects
1145        in a pack file. -1 is the zlib default. 0 means no
1146        compression, and 1..9 are various speed/size tradeoffs, 9 being
1147        slowest.  If not set,  defaults to core.compression.  If that is
1148        not set,  defaults to -1, the zlib default, which is "a default
1149        compromise between speed and compression (currently equivalent
1150        to level 6)."
1151
1152pack.deltaCacheSize::
1153        The maximum memory in bytes used for caching deltas in
1154        linkgit:git-pack-objects[1].
1155        A value of 0 means no limit. Defaults to 0.
1156
1157pack.deltaCacheLimit::
1158        The maximum size of a delta, that is cached in
1159        linkgit:git-pack-objects[1]. Defaults to 1000.
1160
1161pack.threads::
1162        Specifies the number of threads to spawn when searching for best
1163        delta matches.  This requires that linkgit:git-pack-objects[1]
1164        be compiled with pthreads otherwise this option is ignored with a
1165        warning. This is meant to reduce packing time on multiprocessor
1166        machines. The required amount of memory for the delta search window
1167        is however multiplied by the number of threads.
1168        Specifying 0 will cause git to auto-detect the number of CPU's
1169        and set the number of threads accordingly.
1170
1171pack.indexVersion::
1172        Specify the default pack index version.  Valid values are 1 for
1173        legacy pack index used by Git versions prior to 1.5.2, and 2 for
1174        the new pack index with capabilities for packs larger than 4 GB
1175        as well as proper protection against the repacking of corrupted
1176        packs.  Version 2 is the default.  Note that version 2 is enforced
1177        and this config option ignored whenever the corresponding pack is
1178        larger than 2 GB.
1179+
1180If you have an old git that does not understand the version 2 `{asterisk}.idx` file,
1181cloning or fetching over a non native protocol (e.g. "http" and "rsync")
1182that will copy both `{asterisk}.pack` file and corresponding `{asterisk}.idx` file from the
1183other side may give you a repository that cannot be accessed with your
1184older version of git. If the `{asterisk}.pack` file is smaller than 2 GB, however,
1185you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
1186the `{asterisk}.idx` file.
1187
1188pack.packSizeLimit::
1189        The default maximum size of a pack.  This setting only affects
1190        packing to a file, i.e. the git:// protocol is unaffected.  It
1191        can be overridden by the `\--max-pack-size` option of
1192        linkgit:git-repack[1].
1193
1194pager.<cmd>::
1195        Allows turning on or off pagination of the output of a
1196        particular git subcommand when writing to a tty.  If
1197        `\--paginate` or `\--no-pager` is specified on the command line,
1198        it takes precedence over this option.  To disable pagination for
1199        all commands, set `core.pager` or `GIT_PAGER` to `cat`.
1200
1201pull.octopus::
1202        The default merge strategy to use when pulling multiple branches
1203        at once.
1204
1205pull.twohead::
1206        The default merge strategy to use when pulling a single branch.
1207
1208push.default::
1209        Defines the action git push should take if no refspec is given
1210        on the command line, no refspec is configured in the remote, and
1211        no refspec is implied by any of the options given on the command
1212        line. Possible values are:
1213+
1214* `nothing` do not push anything.
1215* `matching` push all matching branches.
1216  All branches having the same name in both ends are considered to be
1217  matching. This is the default.
1218* `tracking` push the current branch to its upstream branch.
1219* `current` push the current branch to a branch of the same name.
1220
1221rebase.stat::
1222        Whether to show a diffstat of what changed upstream since the last
1223        rebase. False by default.
1224
1225receive.fsckObjects::
1226        If it is set to true, git-receive-pack will check all received
1227        objects. It will abort in the case of a malformed object or a
1228        broken link. The result of an abort are only dangling objects.
1229        Defaults to false.
1230
1231receive.unpackLimit::
1232        If the number of objects received in a push is below this
1233        limit then the objects will be unpacked into loose object
1234        files. However if the number of received objects equals or
1235        exceeds this limit then the received pack will be stored as
1236        a pack, after adding any missing delta bases.  Storing the
1237        pack from a push can make the push operation complete faster,
1238        especially on slow filesystems.  If not set, the value of
1239        `transfer.unpackLimit` is used instead.
1240
1241receive.denyDeletes::
1242        If set to true, git-receive-pack will deny a ref update that deletes
1243        the ref. Use this to prevent such a ref deletion via a push.
1244
1245receive.denyCurrentBranch::
1246        If set to true or "refuse", receive-pack will deny a ref update
1247        to the currently checked out branch of a non-bare repository.
1248        Such a push is potentially dangerous because it brings the HEAD
1249        out of sync with the index and working tree. If set to "warn",
1250        print a warning of such a push to stderr, but allow the push to
1251        proceed. If set to false or "ignore", allow such pushes with no
1252        message. Defaults to "warn".
1253
1254receive.denyNonFastForwards::
1255        If set to true, git-receive-pack will deny a ref update which is
1256        not a fast forward. Use this to prevent such an update via a push,
1257        even if that push is forced. This configuration variable is
1258        set when initializing a shared repository.
1259
1260remote.<name>.url::
1261        The URL of a remote repository.  See linkgit:git-fetch[1] or
1262        linkgit:git-push[1].
1263
1264remote.<name>.proxy::
1265        For remotes that require curl (http, https and ftp), the URL to
1266        the proxy to use for that remote.  Set to the empty string to
1267        disable proxying for that remote.
1268
1269remote.<name>.fetch::
1270        The default set of "refspec" for linkgit:git-fetch[1]. See
1271        linkgit:git-fetch[1].
1272
1273remote.<name>.push::
1274        The default set of "refspec" for linkgit:git-push[1]. See
1275        linkgit:git-push[1].
1276
1277remote.<name>.mirror::
1278        If true, pushing to this remote will automatically behave
1279        as if the `\--mirror` option was given on the command line.
1280
1281remote.<name>.skipDefaultUpdate::
1282        If true, this remote will be skipped by default when updating
1283        using the update subcommand of linkgit:git-remote[1].
1284
1285remote.<name>.receivepack::
1286        The default program to execute on the remote side when pushing.  See
1287        option \--receive-pack of linkgit:git-push[1].
1288
1289remote.<name>.uploadpack::
1290        The default program to execute on the remote side when fetching.  See
1291        option \--upload-pack of linkgit:git-fetch-pack[1].
1292
1293remote.<name>.tagopt::
1294        Setting this value to \--no-tags disables automatic tag following when
1295        fetching from remote <name>
1296
1297remotes.<group>::
1298        The list of remotes which are fetched by "git remote update
1299        <group>".  See linkgit:git-remote[1].
1300
1301repack.usedeltabaseoffset::
1302        By default, linkgit:git-repack[1] creates packs that use
1303        delta-base offset. If you need to share your repository with
1304        git older than version 1.4.4, either directly or via a dumb
1305        protocol such as http, then you need to set this option to
1306        "false" and repack. Access from old git versions over the
1307        native protocol are unaffected by this option.
1308
1309rerere.autoupdate::
1310        When set to true, `git-rerere` updates the index with the
1311        resulting contents after it cleanly resolves conflicts using
1312        previously recorded resolution.  Defaults to false.
1313
1314rerere.enabled::
1315        Activate recording of resolved conflicts, so that identical
1316        conflict hunks can be resolved automatically, should they
1317        be encountered again.  linkgit:git-rerere[1] command is by
1318        default enabled if you create `rr-cache` directory under
1319        `$GIT_DIR`, but can be disabled by setting this option to false.
1320
1321showbranch.default::
1322        The default set of branches for linkgit:git-show-branch[1].
1323        See linkgit:git-show-branch[1].
1324
1325status.relativePaths::
1326        By default, linkgit:git-status[1] shows paths relative to the
1327        current directory. Setting this variable to `false` shows paths
1328        relative to the repository root (this was the default for git
1329        prior to v1.5.4).
1330
1331status.showUntrackedFiles::
1332        By default, linkgit:git-status[1] and linkgit:git-commit[1] show
1333        files which are not currently tracked by Git. Directories which
1334        contain only untracked files, are shown with the directory name
1335        only. Showing untracked files means that Git needs to lstat() all
1336        all the files in the whole repository, which might be slow on some
1337        systems. So, this variable controls how the commands displays
1338        the untracked files. Possible values are:
1339+
1340--
1341        - 'no'     - Show no untracked files
1342        - 'normal' - Shows untracked files and directories
1343        - 'all'    - Shows also individual files in untracked directories.
1344--
1345+
1346If this variable is not specified, it defaults to 'normal'.
1347This variable can be overridden with the -u|--untracked-files option
1348of linkgit:git-status[1] and linkgit:git-commit[1].
1349
1350tar.umask::
1351        This variable can be used to restrict the permission bits of
1352        tar archive entries.  The default is 0002, which turns off the
1353        world write bit.  The special value "user" indicates that the
1354        archiving user's umask will be used instead.  See umask(2) and
1355        linkgit:git-archive[1].
1356
1357transfer.unpackLimit::
1358        When `fetch.unpackLimit` or `receive.unpackLimit` are
1359        not set, the value of this variable is used instead.
1360        The default value is 100.
1361
1362url.<base>.insteadOf::
1363        Any URL that starts with this value will be rewritten to
1364        start, instead, with <base>. In cases where some site serves a
1365        large number of repositories, and serves them with multiple
1366        access methods, and some users need to use different access
1367        methods, this feature allows people to specify any of the
1368        equivalent URLs and have git automatically rewrite the URL to
1369        the best alternative for the particular user, even for a
1370        never-before-seen repository on the site.  When more than one
1371        insteadOf strings match a given URL, the longest match is used.
1372
1373user.email::
1374        Your email address to be recorded in any newly created commits.
1375        Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and
1376        'EMAIL' environment variables.  See linkgit:git-commit-tree[1].
1377
1378user.name::
1379        Your full name to be recorded in any newly created commits.
1380        Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
1381        environment variables.  See linkgit:git-commit-tree[1].
1382
1383user.signingkey::
1384        If linkgit:git-tag[1] is not selecting the key you want it to
1385        automatically when creating a signed tag, you can override the
1386        default selection with this variable.  This option is passed
1387        unchanged to gpg's --local-user parameter, so you may specify a key
1388        using any method that gpg supports.
1389
1390web.browser::
1391        Specify a web browser that may be used by some commands.
1392        Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
1393        may use it.
