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 * `blank-at-eof` treats blank lines added at the end of file as an error
393 (enabled by default).
394 * `cr-at-eol` treats a carriage-return at the end of line as
395 part of the line terminator, i.e. with it, `trailing-space`
396 does not trigger if the character before such a carriage-return
397 is not a whitespace (not enabled by default).
398
399 core.fsyncobjectfiles::
400 This boolean will enable 'fsync()' when writing object files.
401 +
402 This is a total waste of time and effort on a filesystem that orders
403 data writes properly, but can be useful for filesystems that do not use
404 journalling (traditional UNIX filesystems) or that only journal metadata
405 and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback").
406
407 alias.*::
408 Command aliases for the linkgit:git[1] command wrapper - e.g.
409 after defining "alias.last = cat-file commit HEAD", the invocation
410 "git last" is equivalent to "git cat-file commit HEAD". To avoid
411 confusion and troubles with script usage, aliases that
412 hide existing git commands are ignored. Arguments are split by
413 spaces, the usual shell quoting and escaping is supported.
414 quote pair and a backslash can be used to quote them.
415 +
416 If the alias expansion is prefixed with an exclamation point,
417 it will be treated as a shell command. For example, defining
418 "alias.new = !gitk --all --not ORIG_HEAD", the invocation
419 "git new" is equivalent to running the shell command
420 "gitk --all --not ORIG_HEAD".
421
422 apply.whitespace::
423 Tells 'git-apply' how to handle whitespaces, in the same way
424 as the '--whitespace' option. See linkgit:git-apply[1].
425
426 branch.autosetupmerge::
427 Tells 'git-branch' and 'git-checkout' to setup new branches
428 so that linkgit:git-pull[1] will appropriately merge from the
429 starting point branch. Note that even if this option is not set,
430 this behavior can be chosen per-branch using the `--track`
431 and `--no-track` options. The valid settings are: `false` -- no
432 automatic setup is done; `true` -- automatic setup is done when the
433 starting point is a remote branch; `always` -- automatic setup is
434 done when the starting point is either a local branch or remote
435 branch. This option defaults to true.
436
437 branch.autosetuprebase::
438 When a new branch is created with 'git-branch' or 'git-checkout'
439 that tracks another branch, this variable tells git to set
440 up pull to rebase instead of merge (see "branch.<name>.rebase").
441 When `never`, rebase is never automatically set to true.
442 When `local`, rebase is set to true for tracked branches of
443 other local branches.
444 When `remote`, rebase is set to true for tracked branches of
445 remote branches.
446 When `always`, rebase will be set to true for all tracking
447 branches.
448 See "branch.autosetupmerge" for details on how to set up a
449 branch to track another branch.
450 This option defaults to never.
451
452 branch.<name>.remote::
453 When in branch <name>, it tells 'git-fetch' which remote to fetch.
454 If this option is not given, 'git-fetch' defaults to remote "origin".
455
456 branch.<name>.merge::
457 When in branch <name>, it tells 'git-fetch' the default
458 refspec to be marked for merging in FETCH_HEAD. The value is
459 handled like the remote part of a refspec, and must match a
460 ref which is fetched from the remote given by
461 "branch.<name>.remote".
462 The merge information is used by 'git-pull' (which at first calls
463 'git-fetch') to lookup the default branch for merging. Without
464 this option, 'git-pull' defaults to merge the first refspec fetched.
465 Specify multiple values to get an octopus merge.
466 If you wish to setup 'git-pull' so that it merges into <name> from
467 another branch in the local repository, you can point
468 branch.<name>.merge to the desired branch, and use the special setting
469 `.` (a period) for branch.<name>.remote.
470
471 branch.<name>.mergeoptions::
472 Sets default options for merging into branch <name>. The syntax and
473 supported options are equal to that of linkgit:git-merge[1], but
474 option values containing whitespace characters are currently not
475 supported.
476
477 branch.<name>.rebase::
478 When true, rebase the branch <name> on top of the fetched branch,
479 instead of merging the default branch from the default remote when
480 "git pull" is run.
481 *NOTE*: this is a possibly dangerous operation; do *not* use
482 it unless you understand the implications (see linkgit:git-rebase[1]
483 for details).
484
485 browser.<tool>.cmd::
486 Specify the command to invoke the specified browser. The
487 specified command is evaluated in shell with the URLs passed
488 as arguments. (See linkgit:git-web--browse[1].)
489
490 browser.<tool>.path::
491 Override the path for the given tool that may be used to
492 browse HTML help (see '-w' option in linkgit:git-help[1]) or a
493 working repository in gitweb (see linkgit:git-instaweb[1]).
494
495 clean.requireForce::
496 A boolean to make git-clean do nothing unless given -f
497 or -n. Defaults to true.
498
499 color.branch::
500 A boolean to enable/disable color in the output of
501 linkgit:git-branch[1]. May be set to `always`,
502 `false` (or `never`) or `auto` (or `true`), in which case colors are used
503 only when the output is to a terminal. Defaults to false.
504
505 color.branch.<slot>::
506 Use customized color for branch coloration. `<slot>` is one of
507 `current` (the current branch), `local` (a local branch),
508 `remote` (a tracking branch in refs/remotes/), `plain` (other
509 refs).
510 +
511 The value for these configuration variables is a list of colors (at most
512 two) and attributes (at most one), separated by spaces. The colors
513 accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`,
514 `magenta`, `cyan` and `white`; the attributes are `bold`, `dim`, `ul`,
515 `blink` and `reverse`. The first color given is the foreground; the
516 second is the background. The position of the attribute, if any,
517 doesn't matter.
518
519 color.diff::
520 When set to `always`, always use colors in patch.
521 When false (or `never`), never. When set to `true` or `auto`, use
522 colors only when the output is to the terminal. Defaults to false.
523
524 color.diff.<slot>::
525 Use customized color for diff colorization. `<slot>` specifies
526 which part of the patch to use the specified color, and is one
527 of `plain` (context text), `meta` (metainformation), `frag`
528 (hunk header), `old` (removed lines), `new` (added lines),
529 `commit` (commit headers), or `whitespace` (highlighting
530 whitespace errors). The values of these variables may be specified as
531 in color.branch.<slot>.
532
533 color.interactive::
534 When set to `always`, always use colors for interactive prompts
535 and displays (such as those used by "git-add --interactive").
536 When false (or `never`), never. When set to `true` or `auto`, use
537 colors only when the output is to the terminal. Defaults to false.
538
539 color.interactive.<slot>::
540 Use customized color for 'git-add --interactive'
541 output. `<slot>` may be `prompt`, `header`, or `help`, for
542 three distinct types of normal output from interactive
543 programs. The values of these variables may be specified as
544 in color.branch.<slot>.
545
546 color.pager::
547 A boolean to enable/disable colored output when the pager is in
548 use (default is true).
549
550 color.status::
551 A boolean to enable/disable color in the output of
552 linkgit:git-status[1]. May be set to `always`,
553 `false` (or `never`) or `auto` (or `true`), in which case colors are used
554 only when the output is to a terminal. Defaults to false.
555
556 color.status.<slot>::
557 Use customized color for status colorization. `<slot>` is
558 one of `header` (the header text of the status message),
559 `added` or `updated` (files which are added but not committed),
560 `changed` (files which are changed but not added in the index),
561 `untracked` (files which are not tracked by git), or
562 `nobranch` (the color the 'no branch' warning is shown in, defaulting
563 to red). The values of these variables may be specified as in
564 color.branch.<slot>.
565
566 color.ui::
567 When set to `always`, always use colors in all git commands which
568 are capable of colored output. When false (or `never`), never. When
569 set to `true` or `auto`, use colors only when the output is to the
570 terminal. When more specific variables of color.* are set, they always
571 take precedence over this setting. Defaults to false.
572
573 commit.template::
574 Specify a file to use as the template for new commit messages.
575
576 diff.autorefreshindex::
577 When using 'git-diff' to compare with work tree
578 files, do not consider stat-only change as changed.
579 Instead, silently run `git update-index --refresh` to
580 update the cached stat information for paths whose
581 contents in the work tree match the contents in the
582 index. This option defaults to true. Note that this
583 affects only 'git-diff' Porcelain, and not lower level
584 'diff' commands, such as 'git-diff-files'.
585
586 diff.external::
587 If this config variable is set, diff generation is not
588 performed using the internal diff machinery, but using the
589 given command. Can be overridden with the `GIT_EXTERNAL_DIFF'
590 environment variable. The command is called with parameters
591 as described under "git Diffs" in linkgit:git[1]. Note: if
592 you want to use an external diff program only on a subset of
593 your files, you might want to use linkgit:gitattributes[5] instead.
594
595 diff.renameLimit::
596 The number of files to consider when performing the copy/rename
597 detection; equivalent to the 'git-diff' option '-l'.
598
599 diff.renames::
600 Tells git to detect renames. If set to any boolean value, it
601 will enable basic rename detection. If set to "copies" or
602 "copy", it will detect copies, as well.
603
604 fetch.unpackLimit::
605 If the number of objects fetched over the git native
606 transfer is below this
607 limit, then the objects will be unpacked into loose object
608 files. However if the number of received objects equals or
609 exceeds this limit then the received pack will be stored as
610 a pack, after adding any missing delta bases. Storing the
611 pack from a push can make the push operation complete faster,
612 especially on slow filesystems. If not set, the value of
613 `transfer.unpackLimit` is used instead.
614
615 format.numbered::
616 A boolean which can enable sequence numbers in patch subjects.
617 Setting this option to "auto" will enable it only if there is
618 more than one patch. See --numbered option in
619 linkgit:git-format-patch[1].
620
621 format.headers::
622 Additional email headers to include in a patch to be submitted
623 by mail. See linkgit:git-format-patch[1].
624
625 format.suffix::
626 The default for format-patch is to output files with the suffix
627 `.patch`. Use this variable to change that suffix (make sure to
628 include the dot if you want it).
629
630 format.pretty::
631 The default pretty format for log/show/whatchanged command,
632 See linkgit:git-log[1], linkgit:git-show[1],
633 linkgit:git-whatchanged[1].
634
635 gc.aggressiveWindow::
636 The window size parameter used in the delta compression
637 algorithm used by 'git-gc --aggressive'. This defaults
638 to 10.
639
640 gc.auto::
641 When there are approximately more than this many loose
642 objects in the repository, `git gc --auto` will pack them.
643 Some Porcelain commands use this command to perform a
644 light-weight garbage collection from time to time. The
645 default value is 6700. Setting this to 0 disables it.
646
647 gc.autopacklimit::
648 When there are more than this many packs that are not
649 marked with `*.keep` file in the repository, `git gc
650 --auto` consolidates them into one larger pack. The
651 default value is 50. Setting this to 0 disables it.
652
653 gc.packrefs::
654 'git-gc' does not run `git pack-refs` in a bare repository by
655 default so that older dumb-transport clients can still fetch
656 from the repository. Setting this to `true` lets 'git-gc'
657 to run `git pack-refs`. Setting this to `false` tells
658 'git-gc' never to run `git pack-refs`. The default setting is
659 `notbare`. Enable it only when you know you do not have to
660 support such clients. The default setting will change to `true`
661 at some stage, and setting this to `false` will continue to
662 prevent `git pack-refs` from being run from 'git-gc'.
663
664 gc.pruneexpire::
665 When 'git-gc' is run, it will call 'prune --expire 2.weeks.ago'.
666 Override the grace period with this config variable.
667
668 gc.reflogexpire::
669 'git-reflog expire' removes reflog entries older than
670 this time; defaults to 90 days.
671
672 gc.reflogexpireunreachable::
673 'git-reflog expire' removes reflog entries older than
674 this time and are not reachable from the current tip;
675 defaults to 30 days.
676
677 gc.rerereresolved::
678 Records of conflicted merge you resolved earlier are
679 kept for this many days when 'git-rerere gc' is run.
680 The default is 60 days. See linkgit:git-rerere[1].
681
682 gc.rerereunresolved::
683 Records of conflicted merge you have not resolved are
684 kept for this many days when 'git-rerere gc' is run.
685 The default is 15 days. See linkgit:git-rerere[1].
686
687 gitcvs.enabled::
688 Whether the CVS server interface is enabled for this repository.
689 See linkgit:git-cvsserver[1].
690
691 gitcvs.logfile::
692 Path to a log file where the CVS server interface well... logs
693 various stuff. See linkgit:git-cvsserver[1].
694
695 gitcvs.usecrlfattr::
696 If true, the server will look up the `crlf` attribute for
697 files to determine the '-k' modes to use. If `crlf` is set,
698 the '-k' mode will be left blank, so cvs clients will
699 treat it as text. If `crlf` is explicitly unset, the file
700 will be set with '-kb' mode, which suppresses any newline munging
701 the client might otherwise do. If `crlf` is not specified,
702 then 'gitcvs.allbinary' is used. See linkgit:gitattributes[5].
703
704 gitcvs.allbinary::
705 This is used if 'gitcvs.usecrlfattr' does not resolve
706 the correct '-kb' mode to use. If true, all
707 unresolved files are sent to the client in
708 mode '-kb'. This causes the client to treat them
709 as binary files, which suppresses any newline munging it
710 otherwise might do. Alternatively, if it is set to "guess",
711 then the contents of the file are examined to decide if
712 it is binary, similar to 'core.autocrlf'.
713
714 gitcvs.dbname::
715 Database used by git-cvsserver to cache revision information
716 derived from the git repository. The exact meaning depends on the
717 used database driver, for SQLite (which is the default driver) this
718 is a filename. Supports variable substitution (see
719 linkgit:git-cvsserver[1] for details). May not contain semicolons (`;`).
720 Default: '%Ggitcvs.%m.sqlite'
721
722 gitcvs.dbdriver::
723 Used Perl DBI driver. You can specify any available driver
724 for this here, but it might not work. git-cvsserver is tested
725 with 'DBD::SQLite', reported to work with 'DBD::Pg', and
726 reported *not* to work with 'DBD::mysql'. Experimental feature.
727 May not contain double colons (`:`). Default: 'SQLite'.
728 See linkgit:git-cvsserver[1].
729
730 gitcvs.dbuser, gitcvs.dbpass::
731 Database user and password. Only useful if setting 'gitcvs.dbdriver',
732 since SQLite has no concept of database users and/or passwords.
733 'gitcvs.dbuser' supports variable substitution (see
734 linkgit:git-cvsserver[1] for details).
735
736 gitcvs.dbTableNamePrefix::
737 Database table name prefix. Prepended to the names of any
738 database tables used, allowing a single database to be used
739 for several repositories. Supports variable substitution (see
740 linkgit:git-cvsserver[1] for details). Any non-alphabetic
741 characters will be replaced with underscores.
742
743 All gitcvs variables except for 'gitcvs.usecrlfattr' and
744 'gitcvs.allbinary' can also be specified as
745 'gitcvs.<access_method>.<varname>' (where 'access_method'
746 is one of "ext" and "pserver") to make them apply only for the given
747 access method.
748
749 gui.commitmsgwidth::
750 Defines how wide the commit message window is in the
751 linkgit:git-gui[1]. "75" is the default.
752
753 gui.diffcontext::
754 Specifies how many context lines should be used in calls to diff
755 made by the linkgit:git-gui[1]. The default is "5".
756
757 gui.matchtrackingbranch::
758 Determines if new branches created with linkgit:git-gui[1] should
759 default to tracking remote branches with matching names or
760 not. Default: "false".
761
762 gui.newbranchtemplate::
763 Is used as suggested name when creating new branches using the
764 linkgit:git-gui[1].
765
766 gui.pruneduringfetch::
767 "true" if linkgit:git-gui[1] should prune tracking branches when
768 performing a fetch. The default value is "false".
769
770 gui.trustmtime::
771 Determines if linkgit:git-gui[1] should trust the file modification
772 timestamp or not. By default the timestamps are not trusted.
773
774 gui.spellingdictionary::
775 Specifies the dictionary used for spell checking commit messages in
776 the linkgit:git-gui[1]. When set to "none" spell checking is turned
777 off.
778
779 help.browser::
780 Specify the browser that will be used to display help in the
781 'web' format. See linkgit:git-help[1].
782
783 help.format::
784 Override the default help format used by linkgit:git-help[1].
785 Values 'man', 'info', 'web' and 'html' are supported. 'man' is
786 the default. 'web' and 'html' are the same.
787
788 http.proxy::
789 Override the HTTP proxy, normally configured using the 'http_proxy'
790 environment variable (see linkgit:curl[1]). This can be overridden
791 on a per-remote basis; see remote.<name>.proxy
792
793 http.sslVerify::
794 Whether to verify the SSL certificate when fetching or pushing
795 over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
796 variable.
797
798 http.sslCert::
799 File containing the SSL certificate when fetching or pushing
800 over HTTPS. Can be overridden by the 'GIT_SSL_CERT' environment
801 variable.
802
803 http.sslKey::
804 File containing the SSL private key when fetching or pushing
805 over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment
806 variable.
807
808 http.sslCAInfo::
809 File containing the certificates to verify the peer with when
810 fetching or pushing over HTTPS. Can be overridden by the
811 'GIT_SSL_CAINFO' environment variable.
812
813 http.sslCAPath::
814 Path containing files with the CA certificates to verify the peer
815 with when fetching or pushing over HTTPS. Can be overridden
816 by the 'GIT_SSL_CAPATH' environment variable.
817
818 http.maxRequests::
819 How many HTTP requests to launch in parallel. Can be overridden
820 by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5.
821
822 http.lowSpeedLimit, http.lowSpeedTime::
823 If the HTTP transfer speed is less than 'http.lowSpeedLimit'
824 for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
825 Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and
826 'GIT_HTTP_LOW_SPEED_TIME' environment variables.
827
828 http.noEPSV::
829 A boolean which disables using of EPSV ftp command by curl.
830 This can helpful with some "poor" ftp servers which don't
831 support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
832 environment variable. Default is false (curl will use EPSV).
833
834 i18n.commitEncoding::
835 Character encoding the commit messages are stored in; git itself
836 does not care per se, but this information is necessary e.g. when
837 importing commits from emails or in the gitk graphical history
838 browser (and possibly at other places in the future or in other
839 porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.
840
841 i18n.logOutputEncoding::
842 Character encoding the commit messages are converted to when
843 running 'git-log' and friends.
844
845 imap::
846 The configuration variables in the 'imap' section are described
847 in linkgit:git-imap-send[1].
848
849 instaweb.browser::
850 Specify the program that will be used to browse your working
851 repository in gitweb. See linkgit:git-instaweb[1].
852
853 instaweb.httpd::
854 The HTTP daemon command-line to start gitweb on your working
855 repository. See linkgit:git-instaweb[1].
856
857 instaweb.local::
858 If true the web server started by linkgit:git-instaweb[1] will
859 be bound to the local IP (127.0.0.1).
860
861 instaweb.modulepath::
862 The module path for an apache httpd used by linkgit:git-instaweb[1].
863
864 instaweb.port::
865 The port number to bind the gitweb httpd to. See
866 linkgit:git-instaweb[1].
867
868 log.date::
869 Set default date-time mode for the log command. Setting log.date
870 value is similar to using 'git-log'\'s --date option. The value is one of the
871 following alternatives: {relative,local,default,iso,rfc,short}.
872 See linkgit:git-log[1].
873
874 log.showroot::
875 If true, the initial commit will be shown as a big creation event.
876 This is equivalent to a diff against an empty tree.
877 Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
878 normally hide the root commit will now show it. True by default.
879
880 man.viewer::
881 Specify the programs that may be used to display help in the
882 'man' format. See linkgit:git-help[1].
883
884 man.<tool>.cmd::
885 Specify the command to invoke the specified man viewer. The
886 specified command is evaluated in shell with the man page
887 passed as argument. (See linkgit:git-help[1].)
888
889 man.<tool>.path::
890 Override the path for the given tool that may be used to
891 display help in the 'man' format. See linkgit:git-help[1].
892
893 include::merge-config.txt[]
894
895 mergetool.<tool>.path::
896 Override the path for the given tool. This is useful in case
897 your tool is not in the PATH.
898
899 mergetool.<tool>.cmd::
900 Specify the command to invoke the specified merge tool. The
901 specified command is evaluated in shell with the following
902 variables available: 'BASE' is the name of a temporary file
903 containing the common base of the files to be merged, if available;
904 'LOCAL' is the name of a temporary file containing the contents of
905 the file on the current branch; 'REMOTE' is the name of a temporary
906 file containing the contents of the file from the branch being
907 merged; 'MERGED' contains the name of the file to which the merge
908 tool should write the results of a successful merge.
909
910 mergetool.<tool>.trustExitCode::
911 For a custom merge command, specify whether the exit code of
912 the merge command can be used to determine whether the merge was
913 successful. If this is not set to true then the merge target file
914 timestamp is checked and the merge assumed to have been successful
915 if the file has been updated, otherwise the user is prompted to
916 indicate the success of the merge.
917
918 mergetool.keepBackup::
919 After performing a merge, the original file with conflict markers
920 can be saved as a file with a `.orig` extension. If this variable
921 is set to `false` then this file is not preserved. Defaults to
922 `true` (i.e. keep the backup files).
923
924 pack.window::
925 The size of the window used by linkgit:git-pack-objects[1] when no
926 window size is given on the command line. Defaults to 10.
927
928 pack.depth::
929 The maximum delta depth used by linkgit:git-pack-objects[1] when no
930 maximum depth is given on the command line. Defaults to 50.
931
932 pack.windowMemory::
933 The window memory size limit used by linkgit:git-pack-objects[1]
934 when no limit is given on the command line. The value can be
935 suffixed with "k", "m", or "g". Defaults to 0, meaning no
936 limit.
937
938 pack.compression::
939 An integer -1..9, indicating the compression level for objects
940 in a pack file. -1 is the zlib default. 0 means no
941 compression, and 1..9 are various speed/size tradeoffs, 9 being
942 slowest. If not set, defaults to core.compression. If that is
943 not set, defaults to -1, the zlib default, which is "a default
944 compromise between speed and compression (currently equivalent
945 to level 6)."
946
947 pack.deltaCacheSize::
948 The maximum memory in bytes used for caching deltas in
949 linkgit:git-pack-objects[1].
950 A value of 0 means no limit. Defaults to 0.
951
952 pack.deltaCacheLimit::
953 The maximum size of a delta, that is cached in
954 linkgit:git-pack-objects[1]. Defaults to 1000.
955
956 pack.threads::
957 Specifies the number of threads to spawn when searching for best
958 delta matches. This requires that linkgit:git-pack-objects[1]
959 be compiled with pthreads otherwise this option is ignored with a
960 warning. This is meant to reduce packing time on multiprocessor
961 machines. The required amount of memory for the delta search window
962 is however multiplied by the number of threads.
963 Specifying 0 will cause git to auto-detect the number of CPU's
964 and set the number of threads accordingly.
965
966 pack.indexVersion::
967 Specify the default pack index version. Valid values are 1 for
968 legacy pack index used by Git versions prior to 1.5.2, and 2 for
969 the new pack index with capabilities for packs larger than 4 GB
970 as well as proper protection against the repacking of corrupted
971 packs. Version 2 is the default. Note that version 2 is enforced
972 and this config option ignored whenever the corresponding pack is
973 larger than 2 GB.
974 +
975 If you have an old git that does not understand the version 2 `{asterisk}.idx` file,
976 cloning or fetching over a non native protocol (e.g. "http" and "rsync")
977 that will copy both `{asterisk}.pack` file and corresponding `{asterisk}.idx` file from the
978 other side may give you a repository that cannot be accessed with your
979 older version of git. If the `{asterisk}.pack` file is smaller than 2 GB, however,
980 you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
981 the `{asterisk}.idx` file.
982
983 pack.packSizeLimit::
984 The default maximum size of a pack. This setting only affects
985 packing to a file, i.e. the git:// protocol is unaffected. It
986 can be overridden by the `\--max-pack-size` option of
987 linkgit:git-repack[1].
988
989 pager.<cmd>::
990 Allows turning on or off pagination of the output of a
991 particular git subcommand when writing to a tty. If
992 `\--paginate` or `\--no-pager` is specified on the command line,
993 it takes precedence over this option. To disable pagination for
994 all commands, set `core.pager` or 'GIT_PAGER' to "`cat`".
995
996 pull.octopus::
997 The default merge strategy to use when pulling multiple branches
998 at once.
999
1000 pull.twohead::
1001 The default merge strategy to use when pulling a single branch.
1002
1003 receive.fsckObjects::
1004 If it is set to true, git-receive-pack will check all received
1005 objects. It will abort in the case of a malformed object or a
1006 broken link. The result of an abort are only dangling objects.
1007 Defaults to false.
1008
1009 receive.unpackLimit::
1010 If the number of objects received in a push is below this
1011 limit then the objects will be unpacked into loose object
1012 files. However if the number of received objects equals or
1013 exceeds this limit then the received pack will be stored as
1014 a pack, after adding any missing delta bases. Storing the
1015 pack from a push can make the push operation complete faster,
1016 especially on slow filesystems. If not set, the value of
1017 `transfer.unpackLimit` is used instead.
1018
1019 receive.denyNonFastForwards::
1020 If set to true, git-receive-pack will deny a ref update which is
1021 not a fast forward. Use this to prevent such an update via a push,
1022 even if that push is forced. This configuration variable is
1023 set when initializing a shared repository.
1024
1025 remote.<name>.url::
1026 The URL of a remote repository. See linkgit:git-fetch[1] or
1027 linkgit:git-push[1].
1028
1029 remote.<name>.proxy::
1030 For remotes that require curl (http, https and ftp), the URL to
1031 the proxy to use for that remote. Set to the empty string to
1032 disable proxying for that remote.
1033
1034 remote.<name>.fetch::
1035 The default set of "refspec" for linkgit:git-fetch[1]. See
1036 linkgit:git-fetch[1].
1037
1038 remote.<name>.push::
1039 The default set of "refspec" for linkgit:git-push[1]. See
1040 linkgit:git-push[1].
1041
1042 remote.<name>.mirror::
1043 If true, pushing to this remote will automatically behave
1044 as if the `\--mirror` option was given on the command line.
1045
1046 remote.<name>.skipDefaultUpdate::
1047 If true, this remote will be skipped by default when updating
1048 using the update subcommand of linkgit:git-remote[1].
1049
1050 remote.<name>.receivepack::
1051 The default program to execute on the remote side when pushing. See
1052 option \--receive-pack of linkgit:git-push[1].
1053
1054 remote.<name>.uploadpack::
1055 The default program to execute on the remote side when fetching. See
1056 option \--upload-pack of linkgit:git-fetch-pack[1].
1057
1058 remote.<name>.tagopt::
1059 Setting this value to \--no-tags disables automatic tag following when
1060 fetching from remote <name>
1061
1062 remotes.<group>::
1063 The list of remotes which are fetched by "git remote update
1064 <group>". See linkgit:git-remote[1].
1065
1066 repack.usedeltabaseoffset::
1067 By default, linkgit:git-repack[1] creates packs that use
1068 delta-base offset. If you need to share your repository with
1069 git older than version 1.4.4, either directly or via a dumb
1070 protocol such as http, then you need to set this option to
1071 "false" and repack. Access from old git versions over the
1072 native protocol are unaffected by this option.
1073
1074 rerere.autoupdate::
1075 When set to true, `git-rerere` updates the index with the
1076 resulting contents after it cleanly resolves conflicts using
1077 previously recorded resolution. Defaults to false.
1078
1079 rerere.enabled::
1080 Activate recording of resolved conflicts, so that identical
1081 conflict hunks can be resolved automatically, should they
1082 be encountered again. linkgit:git-rerere[1] command is by
1083 default enabled if you create `rr-cache` directory under
1084 `$GIT_DIR`, but can be disabled by setting this option to false.
1085
1086 showbranch.default::
1087 The default set of branches for linkgit:git-show-branch[1].
1088 See linkgit:git-show-branch[1].
1089
1090 status.relativePaths::
1091 By default, linkgit:git-status[1] shows paths relative to the
1092 current directory. Setting this variable to `false` shows paths
1093 relative to the repository root (this was the default for git
1094 prior to v1.5.4).
1095
1096 status.showUntrackedFiles::
1097 By default, linkgit:git-status[1] and linkgit:git-commit[1] show
1098 files which are not currently tracked by Git. Directories which
1099 contain only untracked files, are shown with the directory name
1100 only. Showing untracked files means that Git needs to lstat() all
1101 all the files in the whole repository, which might be slow on some
1102 systems. So, this variable controls how the commands displays
1103 the untracked files. Possible values are:
1104 +
1105 --
1106 - 'no' - Show no untracked files
1107 - 'normal' - Shows untracked files and directories
1108 - 'all' - Shows also individual files in untracked directories.
1109 --
1110 +
1111 If this variable is not specified, it defaults to 'normal'.
1112 This variable can be overridden with the -u|--untracked-files option
1113 of linkgit:git-status[1] and linkgit:git-commit[1].
1114
1115 tar.umask::
1116 This variable can be used to restrict the permission bits of
1117 tar archive entries. The default is 0002, which turns off the
1118 world write bit. The special value "user" indicates that the
1119 archiving user's umask will be used instead. See umask(2) and
1120 linkgit:git-archive[1].
1121
1122 transfer.unpackLimit::
1123 When `fetch.unpackLimit` or `receive.unpackLimit` are
1124 not set, the value of this variable is used instead.
1125 The default value is 100.
1126
1127 url.<base>.insteadOf::
1128 Any URL that starts with this value will be rewritten to
1129 start, instead, with <base>. In cases where some site serves a
1130 large number of repositories, and serves them with multiple
1131 access methods, and some users need to use different access
1132 methods, this feature allows people to specify any of the
1133 equivalent URLs and have git automatically rewrite the URL to
1134 the best alternative for the particular user, even for a
1135 never-before-seen repository on the site. When more than one
1136 insteadOf strings match a given URL, the longest match is used.
1137
1138 user.email::
1139 Your email address to be recorded in any newly created commits.
1140 Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and
1141 'EMAIL' environment variables. See linkgit:git-commit-tree[1].
1142
1143 user.name::
1144 Your full name to be recorded in any newly created commits.
1145 Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
1146 environment variables. See linkgit:git-commit-tree[1].
1147
1148 user.signingkey::
1149 If linkgit:git-tag[1] is not selecting the key you want it to
1150 automatically when creating a signed tag, you can override the
1151 default selection with this variable. This option is passed
1152 unchanged to gpg's --local-user parameter, so you may specify a key
1153 using any method that gpg supports.
1154
1155 web.browser::
1156 Specify a web browser that may be used by some commands.
1157 Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
1158 may use it.
