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