1CONFIGURATION FILE
2------------------
3
4The git configuration file contains a number of variables that affect
5ea5621f
JH
5the git command's behavior. `.git/config` file for each repository
6is used to store the information for that repository, and
7`$HOME/.gitconfig` is used to store per user information to give
8fallback values for `.git/config` file.
9
10They can be used by both the git plumbing
b8936cf0 11and the porcelains. The variables are divided into sections, where
1ab661dd
PB
12in the fully qualified variable name the variable itself is the last
13dot-separated segment and the section name is everything before the last
14dot. The variable names are case-insensitive and only alphanumeric
15characters are allowed. Some variables may appear multiple times.

17Syntax
18~~~~~~
19
1ab661dd 20The syntax is fairly flexible and permissive; whitespaces are mostly
e136f33b
JN
21ignored. The '#' and ';' characters begin comments to the end of line,
22blank lines are ignored.
23
24The file consists of sections and variables. A section begins with
25the name of the section in square brackets and continues until the next
26section begins. Section names are not case sensitive. Only alphanumeric
27characters, '`-`' and '`.`' are allowed in section names. Each variable
28must belong to some section, which means that there must be section
29header before first setting of a variable.
30
31Sections can be further divided into subsections. To begin a subsection
32put its name in double quotes, separated by space from the section name,
33in the section header, like in example below:
34
35--------
36 [section "subsection"]
37
38--------
39
40Subsection names can contain any characters (doublequote '`"`', backslash
41'`\`' and newline have to be entered escaped as '`\"`', '`\\`' and '`\n`',
42respecitvely) and are case sensitive. Section header cannot span multiple
43lines. Variables may belong directly to a section or to a given subsection.
44You can have `[section]` if you have `[section "subsection"]`, but you
45don't need to.
46
47There is also (case insensitive) alternative `[section.subsection]` syntax.
48In this syntax subsection names follow the same restrictions as for section
49name.
50
51All the other lines are recognized as setting variables, in the form
52'name = value'. If there is no equal sign on the line, the entire line
53is taken as 'name' and the variable is recognized as boolean "true".
54The variable names are case-insensitive and only alphanumeric
55characters and '`-`' are allowed. There can be more than one value
56for a given variable; we say then that variable is multivalued.
57
58Leading and trailing whitespace in a variable value is discarded.
59Internal whitespace within a variable value is retained verbatim.
60
61The values following the equals sign in variable assign are all either
62a string, an integer, or a boolean. Boolean values may be given as yes/no,
630/1 or true/false. Case is not significant in boolean values, when
64converting value to the canonical form using '--bool' type specifier;
65`git-repo-config` will ensure that the output is "true" or "false".
66
67String values may be entirely or partially enclosed in double quotes.
68You need to enclose variable value in double quotes if you want to
69preserve leading or trailing whitespace, or if variable value contains
70beginning of comment characters (if it contains '#' or ';').
71Double quote '`"`' and backslash '`\`' characters in variable value must
72be escaped: use '`\"`' for '`"`' and '`\\`' for '`\`'.
73
74The following escape sequences (beside '`\"`' and '`\\`') are recognized:
75'`\n`' for newline character (NL), '`\t`' for horizontal tabulation (HT, TAB)
76and '`\b`' for backspace (BS). No other char escape sequence, nor octal
77char sequences are valid.
78
79Variable value ending in a '`\`' is continued on the next line in the
80customary UNIX fashion.
81
82Some variables may require special value format.

110For command-specific variables, you will find a more detailed description
111in the appropriate manual page. You will find a description of non-core
1ab661dd
PB
112porcelain configuration variables in the respective porcelain documentation.
113
114core.fileMode::
115 If false, the executable bit differences between the index and
116 the working copy are ignored; useful on broken filesystems like FAT.
117 See gitlink:git-update-index[1]. True by default.
118
119core.gitProxy::
120 A "proxy command" to execute (as 'command host port') instead
121 of establishing direct connection to the remote server when
122 using the git protocol for fetching. If the variable value is
123 in the "COMMAND for DOMAIN" format, the command is applied only
124 on hostnames ending with the specified domain string. This variable
125 may be set multiple times and is matched in the given order;
126 the first match wins.
b8936cf0
FD
127+
128Can be overridden by the 'GIT_PROXY_COMMAND' environment variable
129(which always applies universally, without the special "for"
130handling).
1ab661dd
PB
131
132core.ignoreStat::
133 The working copy files are assumed to stay unchanged until you
134 mark them otherwise manually - Git will not detect the file changes
135 by lstat() calls. This is useful on systems where those are very
136 slow, such as Microsoft Windows. See gitlink:git-update-index[1].
137 False by default.
138
9f0bb90d
JH
139core.preferSymlinkRefs::
140 Instead of the default "symref" format for HEAD
141 and other symbolic reference files, use symbolic links.
142 This is sometimes needed to work with old scripts that
143 expect HEAD to be a symbolic link.
1ab661dd 144
6de08ae6 145core.logAllRefUpdates::
4057deb5
JH
146 Updates to a ref <ref> is logged to the file
147 "$GIT_DIR/logs/<ref>", by appending the new and old
148 SHA1, the date/time and the reason of the update, but
149 only when the file exists. If this configuration
150 variable is set to true, missing "$GIT_DIR/logs/<ref>"
151 file is automatically created for branch heads.
a862f97e
JH
152+
153This information can be used to determine what commit
154was the tip of a branch "2 days ago".
155+
156This value is true by default in a repository that has
157a working directory associated with it, and false by
158default in a bare repository.
6de08ae6 159
1ab661dd
PB
160core.repositoryFormatVersion::
161 Internal variable identifying the repository format and layout
162 version.
163
164core.sharedRepository::
d5dc6a76
JF
165 When 'group' (or 'true'), the repository is made shareable between
166 several users in a group (making sure all the files and objects are
167 group-writable). When 'all' (or 'world' or 'everybody'), the
168 repository will be readable by all users, additionally to being
169 group-shareable. When 'umask' (or 'false'), git will use permissions
5c94f87e 170 reported by umask(2). See gitlink:git-init[1]. False by default.
1ab661dd
PB
171
172core.warnAmbiguousRefs::
173 If true, git will warn you if the ref name you passed it is ambiguous
174 and might match multiple refs in the .git/refs/ tree. True by default.
175
3d3e95af 176core.compression::
12f6c308
JBH
177 An integer -1..9, indicating the compression level for objects that
178 are not in a pack file. -1 is the zlib and git default. 0 means no
179 compression, and 1..9 are various speed/size tradeoffs, 9 being
180 slowest.
181
93821bd9
LT
182core.legacyheaders::
183 A boolean which enables the legacy object header format in case
184 you want to interoperate with old clients accessing the object
185 database directly (where the "http://" and "rsync://" protocols
186 count as direct access).
187
60bb8b14
SP
188core.packedGitWindowSize::
189 Number of bytes of a pack file to map into memory in a
190 single mapping operation. Larger window sizes may allow
191 your system to process a smaller number of large pack files
192 more quickly. Smaller window sizes will negatively affect
eb92242f 193 performance due to increased calls to the operating system's
60bb8b14 194 memory manager, but may improve performance when accessing
22bac0ea
SP
195 a large number of large pack files.
196+
197Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
198MiB on 32 bit platforms and 1 GiB on 64 bit platforms. This should
199be reasonable for all users/operating systems. You probably do
200not need to adjust this value.
eb92242f
SP
201+
202Common unit suffixes of 'k', 'm', or 'g' are supported.
60bb8b14 203
77ccc5bb
SP
204core.packedGitLimit::
205 Maximum number of bytes to map simultaneously into memory
206 from pack files. If Git needs to access more than this many
207 bytes at once to complete an operation it will unmap existing
208 regions to reclaim virtual address space within the process.
22bac0ea
SP
209+
210Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms.
211This should be reasonable for all users/operating systems, except on
212the largest projects. You probably do not need to adjust this value.
eb92242f
SP
213+
214Common unit suffixes of 'k', 'm', or 'g' are supported.
77ccc5bb 215
4514ad4f
PB
216alias.*::
217 Command aliases for the gitlink:git[1] command wrapper - e.g.
218 after defining "alias.last = cat-file commit HEAD", the invocation
219 "git last" is equivalent to "git cat-file commit HEAD". To avoid
99b41c84
PB
220 confusion and troubles with script usage, aliases that
221 hide existing git commands are ignored. Arguments are split by
222 spaces, the usual shell quoting and escaping is supported.
223 quote pair and a backslash can be used to quote them.
4514ad4f 224
1ab661dd
PB
225apply.whitespace::
226 Tells `git-apply` how to handle whitespaces, in the same way
227 as the '--whitespace' option. See gitlink:git-apply[1].
228
648ad18f
SB
229branch.<name>.remote::
230 When in branch <name>, it tells `git fetch` which remote to fetch.
62b339a5 231 If this option is not given, `git fetch` defaults to remote "origin".
648ad18f 232
5372806a 233branch.<name>.merge::
62b339a5
JW
234 When in branch <name>, it tells `git fetch` the default refspec to
235 be marked for merging in FETCH_HEAD. The value has exactly to match
236 a remote part of one of the refspecs which are fetched from the remote
237 given by "branch.<name>.remote".
238 The merge information is used by `git pull` (which at first calls
239 `git fetch`) to lookup the default branch for merging. Without
240 this option, `git pull` defaults to merge the first refspec fetched.
241 Specify multiple values to get an octopus merge.
5372806a 242
f3673988

243color.branch::
244 A boolean to enable/disable color in the output of

253 refs), or `reset` (the normal terminal color). The value for
254 these configuration variables can be one of: `normal`, `bold`,
255 `dim`, `ul`, `blink`, `reverse`, `reset`, `black`, `red`,
256 `green`, `yellow`, `blue`, `magenta`, `cyan`, or `white`.
257
a159ca0c 258color.diff::
b5376648
JH
259 When true (or `always`), always use colors in patch.
260 When false (or `never`), never. When set to `auto`, use
261 colors only when the output is to the terminal.
262
a159ca0c 263color.diff.<slot>::
b5376648
JH
264 Use customized color for diff colorization. `<slot>`
265 specifies which part of the patch to use the specified
266 color, and is one of `plain` (context text), `meta`
267 (metainformation), `frag` (hunk header), `old` (removed
f3673988
BG
268 lines), or `new` (added lines). The values of these
269 variables may be specified as in color.branch.<slot>.
b5376648 270
1d77043b
JH
271color.pager::
272 A boolean to enable/disable colored output when the pager is in
273 use (default is true).
274
275color.status::
276 A boolean to enable/disable color in the output of
277 gitlink:git-status[1]. May be set to `true` (or `always`),
278 `false` (or `never`) or `auto`, in which case colors are used
279 only when the output is to a terminal. Defaults to false.
280
281color.status.<slot>::
282 Use customized color for status colorization. `<slot>` is
283 one of `header` (the header text of the status message),
82dca848
SP
284 `added` or `updated` (files which are added but not committed),
285 `changed` (files which are changed but not added in the index),
1d77043b 286 or `untracked` (files which are not tracked by git). The values of
f3673988 287 these variables may be specified as in color.branch.<slot>.
1d77043b 288
1ab661dd
PB
289diff.renameLimit::

370i18n.commitEncoding::
371 Character encoding the commit messages are stored in; git itself
372 does not care per se, but this information is necessary e.g. when
373 importing commits from emails or in the gitk graphical history
374 browser (and possibly at other places in the future or in other

7fe08af4 438 By default, gitlink:git-tar-tree[1] sets file and directories modes
ce1a79b6
WT
439 to 0666 or 0777. While this is both useful and acceptable for projects
440 such as the Linux Kernel, it might be excessive for other projects.
441 With this variable, it becomes possible to tell
7fe08af4 442 gitlink:git-tar-tree[1] to apply a specific umask to the modes above.
ce1a79b6
WT
443 The special value "user" indicates that the user's current umask will
444 be used. This should be enough for most projects, as it will lead to
7fe08af4 445 the same permissions as gitlink:git-checkout[1] would use. The default
ce1a79b6
WT
446 value remains 0, which means world read-write.

fc04c412
SP
466receive.unpackLimit::
467 If the number of objects received in a push is below this
