1 CONFIGURATION FILE
2 ------------------
3
4 The git configuration file contains a number of variables that affect
5 the git command's behavior. `.git/config` file for each repository
6 is used to store the information for that repository, and
7 `$HOME/.gitconfig` is used to store per user information to give
8 fallback values for `.git/config` file. The file `/etc/gitconfig`
9 can be used to store system-wide defaults.
10
11 They can be used by both the git plumbing
12 and the porcelains. The variables are divided into sections, where
13 in the fully qualified variable name the variable itself is the last
14 dot-separated segment and the section name is everything before the last
15 dot. The variable names are case-insensitive and only alphanumeric
16 characters are allowed. Some variables may appear multiple times.
17
18 Syntax
19 ~~~~~~
20
21 The syntax is fairly flexible and permissive; whitespaces are mostly
22 ignored. The '#' and ';' characters begin comments to the end of line,
23 blank lines are ignored.
24
25 The file consists of sections and variables. A section begins with
26 the name of the section in square brackets and continues until the next
27 section begins. Section names are not case sensitive. Only alphanumeric
28 characters, '`-`' and '`.`' are allowed in section names. Each variable
29 must belong to some section, which means that there must be section
30 header before first setting of a variable.
31
32 Sections can be further divided into subsections. To begin a subsection
33 put its name in double quotes, separated by space from the section name,
34 in the section header, like in example below:
35
36 --------
37 [section "subsection"]
38
39 --------
40
41 Subsection names can contain any characters except newline (doublequote
42 '`"`' and backslash have to be escaped as '`\"`' and '`\\`',
43 respectively) and are case sensitive. Section header cannot span multiple
44 lines. Variables may belong directly to a section or to a given subsection.
45 You can have `[section]` if you have `[section "subsection"]`, but you
46 don't need to.
47
48 There is also (case insensitive) alternative `[section.subsection]` syntax.
49 In this syntax subsection names follow the same restrictions as for section
50 name.
51
52 All 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
54 is taken as 'name' and the variable is recognized as boolean "true".
55 The variable names are case-insensitive and only alphanumeric
56 characters and '`-`' are allowed. There can be more than one value
57 for a given variable; we say then that variable is multivalued.
58
59 Leading and trailing whitespace in a variable value is discarded.
60 Internal whitespace within a variable value is retained verbatim.
61
62 The values following the equals sign in variable assign are all either
63 a string, an integer, or a boolean. Boolean values may be given as yes/no,
64 0/1 or true/false. Case is not significant in boolean values, when
65 converting value to the canonical form using '--bool' type specifier;
66 'git-config' will ensure that the output is "true" or "false".
67
68 String values may be entirely or partially enclosed in double quotes.
69 You need to enclose variable value in double quotes if you want to
70 preserve leading or trailing whitespace, or if variable value contains
71 beginning of comment characters (if it contains '#' or ';').
72 Double quote '`"`' and backslash '`\`' characters in variable value must
73 be escaped: use '`\"`' for '`"`' and '`\\`' for '`\`'.
74
75 The following escape sequences (beside '`\"`' and '`\\`') are recognized:
76 '`\n`' for newline character (NL), '`\t`' for horizontal tabulation (HT, TAB)
77 and '`\b`' for backspace (BS). No other char escape sequence, nor octal
78 char sequences are valid.
79
80 Variable value ending in a '`\`' is continued on the next line in the
81 customary UNIX fashion.
82
83 Some variables may require special value format.

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