DESCRIPTION

You can query/set/replace/unset options with this command. The name is actually the section and the key separated by a dot, and the value will be escaped.

Multiple lines can be added to an option by using the --add option. If you want to update or unset an option which can occur on multiple lines, a POSIX regexp value_regex needs to be given. Only the existing values that match the regexp are updated or unset. If you want to handle the lines that do not match the regex, just prepend a single exclamation mark in front (see EXAMPLES).

The type specifier can be either --int or --bool, which will make git-config ensure that the variable(s) are of the given type and convert the value to the canonical form (simple decimal number for int, a "true" or "false" string for bool). If no type specifier is passed, no checks or transformations are performed on the value.

This command will fail if:

  1. The .git/config file is invalid,

  2. Can not write to .git/config,

  3. no section was provided,

  4. the section or key is invalid,

  5. you try to unset an option which does not exist,

  6. you try to unset/set an option for which multiple lines match, or

  7. you use --global option without $HOME being properly set.

OPTIONS

--replace-all

Default behavior is to replace at most one line. This replaces all lines matching the key (and optionally the value_regex).

--add

Adds a new line to the option without altering any existing values. This is the same as providing ^$ as the value_regex.

--get

Get the value for a given key (optionally filtered by a regex matching the value). Returns error code 1 if the key was not found and error code 2 if multiple key values were found.

--get-all

Like get, but does not fail if the number of values for the key is not exactly one.

--get-regexp

Like --get-all, but interprets the name as a regular expression.

--global

Use global ~/.gitconfig file rather than the repository .git/config.

--remove-section

Remove the given section from the configuration file.

--rename-section

Rename the given section to a new name.

--unset

Remove the line matching the key from config file.

--unset-all

Remove all lines matching the key from config file.

-l, --list

List all variables set in config file.

--bool

git-config will ensure that the output is "true" or "false"

--int

git-config will ensure that the output is a simple decimal number. An optional value suffix of k, m, or g in the config file will cause the value to be multiplied by 1024, 1048576, or 1073741824 prior to output.

ENVIRONMENT

GIT_CONFIG

Take the configuration from the given file instead of .git/config. Using the "--global" option forces this to ~/.gitconfig.

GIT_CONFIG_LOCAL

Currently the same as $GIT_CONFIG; when Git will support global configuration files, this will cause it to take the configuration from the global configuration file in addition to the given file.

EXAMPLE

Given a .git/config like this:

#
# This is the config file, and
# a '#' or ';' character indicates
# a comment
#
; core variables
[core]
        ; Don't trust file modes
        filemode = false
; Our diff algorithm
[diff]
        external = "/usr/local/bin/gnu-diff -u"
        renames = true
; Proxy settings
[core]
        gitproxy="ssh" for "ssh://kernel.org/"
        gitproxy="proxy-command" for kernel.org
        gitproxy="myprotocol-command" for "my://"
        gitproxy=default-proxy ; for all the rest

you can set the filemode to true with

% git config core.filemode true

The hypothetical proxy command entries actually have a postfix to discern what URL they apply to. Here is how to change the entry for kernel.org to "ssh".

% git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'

This makes sure that only the key/value pair for kernel.org is replaced.

To delete the entry for renames, do

% git config --unset diff.renames

If you want to delete an entry for a multivar (like core.gitproxy above), you have to provide a regex matching the value of exactly one line.

To query the value for a given key, do

% git config --get core.filemode

or

% git config core.filemode

or, to query a multivar:

% git config --get core.gitproxy "for kernel.org$"

If you want to know all the values for a multivar, do:

% git config --get-all core.gitproxy

If you like to live dangerous, you can replace all core.gitproxy by a new one with

% git config --replace-all core.gitproxy ssh

However, if you really only want to replace the line for the default proxy, i.e. the one without a "for …" postfix, do something like this:

% git config core.gitproxy ssh '! for '

To actually match only values with an exclamation mark, you have to

% git config section.key value '[!]'

To add a new proxy, without altering any of the existing ones, use

% git config core.gitproxy '"proxy" for example.com'

CONFIGURATION FILE

The git configuration file contains a number of variables that affect the git command’s behavior. .git/config file for each repository is used to store the information for that repository, and $HOME/.gitconfig is used to store per user information to give fallback values for .git/config file. The file /etc/gitconfig can be used to store system-wide defaults.

They can be used by both the git plumbing and the porcelains. The variables are divided into sections, where in the fully qualified variable name the variable itself is the last dot-separated segment and the section name is everything before the last dot. The variable names are case-insensitive and only alphanumeric characters are allowed. Some variables may appear multiple times.

Syntax

The syntax is fairly flexible and permissive; whitespaces are mostly ignored. The # and ; characters begin comments to the end of line, blank lines are ignored.

The file consists of sections and variables. A section begins with the name of the section in square brackets and continues until the next section begins. Section names are not case sensitive. Only alphanumeric characters, - and . are allowed in section names. Each variable must belong to some section, which means that there must be section header before first setting of a variable.

Sections can be further divided into subsections. To begin a subsection put its name in double quotes, separated by space from the section name, in the section header, like in example below:

        [section "subsection"]

Subsection names can contain any characters except newline (doublequote " and backslash have to be escaped as \" and \\, respectively) and are case sensitive. Section header cannot span multiple lines. Variables may belong directly to a section or to a given subsection. You can have [section] if you have [section "subsection"], but you don’t need to.

There is also (case insensitive) alternative [section.subsection] syntax. In this syntax subsection names follow the same restrictions as for section name.

All the other lines are recognized as setting variables, in the form name = value. If there is no equal sign on the line, the entire line is taken as name and the variable is recognized as boolean "true". The variable names are case-insensitive and only alphanumeric characters and - are allowed. There can be more than one value for a given variable; we say then that variable is multivalued.

Leading and trailing whitespace in a variable value is discarded. Internal whitespace within a variable value is retained verbatim.

The values following the equals sign in variable assign are all either a string, an integer, or a boolean. Boolean values may be given as yes/no, 0/1 or true/false. Case is not significant in boolean values, when converting value to the canonical form using --bool type specifier; git-config will ensure that the output is "true" or "false".

String values may be entirely or partially enclosed in double quotes. You need to enclose variable value in double quotes if you want to preserve leading or trailing whitespace, or if variable value contains beginning of comment characters (if it contains # or ;). Double quote " and backslash \ characters in variable value must be escaped: use \" for " and \\ for \.

The following escape sequences (beside \" and \\) are recognized: \n for newline character (NL), \t for horizontal tabulation (HT, TAB) and \b for backspace (BS). No other char escape sequence, nor octal char sequences are valid.

Variable value ending in a \ is continued on the next line in the customary UNIX fashion.

Some variables may require special value format.

Example

# Core variables
[core]
        ; Don't trust file modes
        filemode = false
# Our diff algorithm
[diff]
        external = "/usr/local/bin/gnu-diff -u"
        renames = true
[branch "devel"]
        remote = origin
        merge = refs/heads/devel
# Proxy settings
[core]
        gitProxy="ssh" for "ssh://kernel.org/"
        gitProxy=default-proxy ; for the rest

Variables

Note that this list is non-comprehensive and not necessarily complete. For command-specific variables, you will find a more detailed description in the appropriate manual page. You will find a description of non-core porcelain configuration variables in the respective porcelain documentation.

core.fileMode

If false, the executable bit differences between the index and the working copy are ignored; useful on broken filesystems like FAT. See gitlink:git-update-index[1]. True by default.

core.symlinks

If false, symbolic links are checked out as small plain files that contain the link text. gitlink:git-update-index[1] and gitlink:git-add[1] will not change the recorded type to regular file. Useful on filesystems like FAT that do not support symbolic links. True by default.

core.gitProxy

A "proxy command" to execute (as command host port) instead of establishing direct connection to the remote server when using the git protocol for fetching. If the variable value is in the "COMMAND for DOMAIN" format, the command is applied only on hostnames ending with the specified domain string. This variable may be set multiple times and is matched in the given order; the first match wins.

Can be overridden by the GIT_PROXY_COMMAND environment variable (which always applies universally, without the special "for" handling).

core.ignoreStat

The working copy files are assumed to stay unchanged until you mark them otherwise manually - Git will not detect the file changes by lstat() calls. This is useful on systems where those are very slow, such as Microsoft Windows. See gitlink:git-update-index[1]. False by default.

core.preferSymlinkRefs

Instead of the default "symref" format for HEAD and other symbolic reference files, use symbolic links. This is sometimes needed to work with old scripts that expect HEAD to be a symbolic link.

core.bare

If true this repository is assumed to be bare and has no working directory associated with it. If this is the case a number of commands that require a working directory will be disabled, such as gitlink:git-add[1] or gitlink:git-merge[1].

This setting is automatically guessed by gitlink:git-clone[1] or gitlink:git-init[1] when the repository was created. By default a repository that ends in "/.git" is assumed to be not bare (bare = false), while all other repositories are assumed to be bare (bare = true).

core.logAllRefUpdates

Updates to a ref <ref> is logged to the file "$GIT_DIR/logs/<ref>", by appending the new and old SHA1, the date/time and the reason of the update, but only when the file exists. If this configuration variable is set to true, missing "$GIT_DIR/logs/<ref>" file is automatically created for branch heads.

This information can be used to determine what commit was the tip of a branch "2 days ago".

This value is true by default in a repository that has a working directory associated with it, and false by default in a bare repository.

core.repositoryFormatVersion

Internal variable identifying the repository format and layout version.

core.sharedRepository

When group (or true), the repository is made shareable between several users in a group (making sure all the files and objects are group-writable). When all (or world or everybody), the repository will be readable by all users, additionally to being group-shareable. When umask (or false), git will use permissions reported by umask(2). See gitlink:git-init[1]. False by default.

core.warnAmbiguousRefs

If true, git will warn you if the ref name you passed it is ambiguous and might match multiple refs in the .git/refs/ tree. True by default.

core.compression

An integer -1..9, indicating the compression level for objects that are not in a pack file. -1 is the zlib and git default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest.

core.legacyheaders

A boolean which changes the format of loose objects so that they are more efficient to pack and to send out of the repository over git native protocol, since v1.4.2. However, loose objects written in the new format cannot be read by git older than that version; people fetching from your repository using older versions of git over dumb transports (e.g. http) will also be affected.

To let git use the new loose object format, you have to set core.legacyheaders to false.

core.packedGitWindowSize

Number of bytes of a pack file to map into memory in a single mapping operation. Larger window sizes may allow your system to process a smaller number of large pack files more quickly. Smaller window sizes will negatively affect performance due to increased calls to the operating system’s memory manager, but may improve performance when accessing a large number of large pack files.

Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32 MiB on 32 bit platforms and 1 GiB on 64 bit platforms. This should be reasonable for all users/operating systems. You probably do not need to adjust this value.

Common unit suffixes of k, m, or g are supported.

core.packedGitLimit

Maximum number of bytes to map simultaneously into memory from pack files. If Git needs to access more than this many bytes at once to complete an operation it will unmap existing regions to reclaim virtual address space within the process.

Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms. This should be reasonable for all users/operating systems, except on the largest projects. You probably do not need to adjust this value.

Common unit suffixes of k, m, or g are supported.

core.deltaBaseCacheLimit

Maximum number of bytes to reserve for caching base objects that multiple deltafied objects reference. By storing the entire decompressed base objects in a cache Git is able to avoid unpacking and decompressing frequently used base objects multiple times.

Default is 16 MiB on all platforms. This should be reasonable for all users/operating systems, except on the largest projects. You probably do not need to adjust this value.

Common unit suffixes of k, m, or g are supported.

alias.*

Command aliases for the gitlink:git[1] command wrapper - e.g. after defining "alias.last = cat-file commit HEAD", the invocation "git last" is equivalent to "git cat-file commit HEAD". To avoid confusion and troubles with script usage, aliases that hide existing git commands are ignored. Arguments are split by spaces, the usual shell quoting and escaping is supported. quote pair and a backslash can be used to quote them.

If the alias expansion is prefixed with an exclamation point,
it will be treated as a shell command.  For example, defining
"alias.new = !gitk --all --not ORIG_HEAD", the invocation
"git new" is equivalent to running the shell command
"gitk --all --not ORIG_HEAD".
apply.whitespace

Tells git-apply how to handle whitespaces, in the same way as the --whitespace option. See gitlink:git-apply[1].

branch.<name>.remote

When in branch <name>, it tells git fetch which remote to fetch. If this option is not given, git fetch defaults to remote "origin".

branch.<name>.merge

When in branch <name>, it tells git fetch the default refspec to be marked for merging in FETCH_HEAD. The value has exactly to match a remote part of one of the refspecs which are fetched from the remote given by "branch.<name>.remote". The merge information is used by git pull (which at first calls git fetch) to lookup the default branch for merging. Without this option, git pull defaults to merge the first refspec fetched. Specify multiple values to get an octopus merge. If you wish to setup git pull so that it merges into <name> from another branch in the local repository, you can point branch.<name>.merge to the desired branch, and use the special setting . (a period) for branch.<name>.remote.

color.branch

A boolean to enable/disable color in the output of gitlink:git-branch[1]. May be set to true (or always), false (or never) or auto, in which case colors are used only when the output is to a terminal. Defaults to false.

color.branch.<slot>

Use customized color for branch coloration. <slot> is one of current (the current branch), local (a local branch), remote (a tracking branch in refs/remotes/), plain (other refs).

The value for these configuration variables is a list of colors (at most two) and attributes (at most one), separated by spaces. The colors accepted are normal, black, red, green, yellow, blue, magenta, cyan and white; the attributes are bold, dim, ul, blink and reverse. The first color given is the foreground; the second is the background. The position of the attribute, if any, doesn’t matter.

color.diff

When true (or always), always use colors in patch. When false (or never), never. When set to auto, use colors only when the output is to the terminal.

color.diff.<slot>

Use customized color for diff colorization. <slot> specifies which part of the patch to use the specified color, and is one of plain (context text), meta (metainformation), frag (hunk header), old (removed lines), new (added lines), commit (commit headers), or whitespace (highlighting dubious whitespace). The values of these variables may be specified as in color.branch.<slot>.

color.pager

A boolean to enable/disable colored output when the pager is in use (default is true).

color.status

A boolean to enable/disable color in the output of gitlink:git-status[1]. May be set to true (or always), false (or never) or auto, in which case colors are used only when the output is to a terminal. Defaults to false.

color.status.<slot>

Use customized color for status colorization. <slot> is one of header (the header text of the status message), added or updated (files which are added but not committed), changed (files which are changed but not added in the index), or untracked (files which are not tracked by git). The values of these variables may be specified as in color.branch.<slot>.

diff.renameLimit

The number of files to consider when performing the copy/rename detection; equivalent to the git diff option -l.

diff.renames

Tells git to detect renames. If set to any boolean value, it will enable basic rename detection. If set to "copies" or "copy", it will detect copies, as well.

fetch.unpackLimit

If the number of objects fetched over the git native transfer is below this limit, then the objects will be unpacked into loose object files. However if the number of received objects equals or exceeds this limit then the received pack will be stored as a pack, after adding any missing delta bases. Storing the pack from a push can make the push operation complete faster, especially on slow filesystems.

format.headers

Additional email headers to include in a patch to be submitted by mail. See gitlink:git-format-patch[1].

format.suffix

The default for format-patch is to output files with the suffix .patch. Use this variable to change that suffix (make sure to include the dot if you want it).

gc.packrefs

git gc does not run git pack-refs in a bare repository by default so that older dumb-transport clients can still fetch from the repository. Setting this to true lets git gc to run git pack-refs. Setting this to false tells git gc never to run git pack-refs. The default setting is notbare. Enable it only when you know you do not have to support such clients. The default setting will change to true at some stage, and setting this to false will continue to prevent git pack-refs from being run from git gc.

gc.reflogexpire

git reflog expire removes reflog entries older than this time; defaults to 90 days.

gc.reflogexpireunreachable

git reflog expire removes reflog entries older than this time and are not reachable from the current tip; defaults to 30 days.

gc.rerereresolved

Records of conflicted merge you resolved earlier are kept for this many days when git rerere gc is run. The default is 60 days. See gitlink:git-rerere[1].

gc.rerereunresolved

Records of conflicted merge you have not resolved are kept for this many days when git rerere gc is run. The default is 15 days. See gitlink:git-rerere[1].

gitcvs.enabled

Whether the cvs pserver interface is enabled for this repository. See gitlink:git-cvsserver[1].

gitcvs.logfile

Path to a log file where the cvs pserver interface well… logs various stuff. See gitlink:git-cvsserver[1].

http.sslVerify

Whether to verify the SSL certificate when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_NO_VERIFY environment variable.

http.sslCert

File containing the SSL certificate when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_CERT environment variable.

http.sslKey

File containing the SSL private key when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_KEY environment variable.

http.sslCAInfo

File containing the certificates to verify the peer with when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_CAINFO environment variable.

http.sslCAPath

Path containing files with the CA certificates to verify the peer with when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_CAPATH environment variable.

http.maxRequests

How many HTTP requests to launch in parallel. Can be overridden by the GIT_HTTP_MAX_REQUESTS environment variable. Default is 5.

http.lowSpeedLimit, http.lowSpeedTime

If the HTTP transfer speed is less than http.lowSpeedLimit for longer than http.lowSpeedTime seconds, the transfer is aborted. Can be overridden by the GIT_HTTP_LOW_SPEED_LIMIT and GIT_HTTP_LOW_SPEED_TIME environment variables.

http.noEPSV

A boolean which disables using of EPSV ftp command by curl. This can helpful with some "poor" ftp servers which doesn’t support EPSV mode. Can be overridden by the GIT_CURL_FTP_NO_EPSV environment variable. Default is false (curl will use EPSV).

i18n.commitEncoding

Character encoding the commit messages are stored in; git itself does not care per se, but this information is necessary e.g. when importing commits from emails or in the gitk graphical history browser (and possibly at other places in the future or in other porcelains). See e.g. gitlink:git-mailinfo[1]. Defaults to utf-8.

i18n.logOutputEncoding

Character encoding the commit messages are converted to when running git-log and friends.

log.showroot

If true, the initial commit will be shown as a big creation event. This is equivalent to a diff against an empty tree. Tools like gitlink:git-log[1] or gitlink:git-whatchanged[1], which normally hide the root commit will now show it. True by default.

merge.summary

Whether to include summaries of merged commits in newly created merge commit messages. False by default.

merge.tool

Controls which merge resolution program is used by gitlink:git-mergetool[l]. Valid values are: "kdiff3", "tkdiff", "meld", "xxdiff", "emerge", "vimdiff"

merge.verbosity

Controls the amount of output shown by the recursive merge strategy. Level 0 outputs nothing except a final error message if conflicts were detected. Level 1 outputs only conflicts, 2 outputs conflicts and file changes. Level 5 and above outputs debugging information. The default is level 2.

pack.window

The size of the window used by gitlink:git-pack-objects[1] when no window size is given on the command line. Defaults to 10.

pull.octopus

The default merge strategy to use when pulling multiple branches at once.

pull.twohead

The default merge strategy to use when pulling a single branch.

remote.<name>.url

The URL of a remote repository. See gitlink:git-fetch[1] or gitlink:git-push[1].

remote.<name>.fetch

The default set of "refspec" for gitlink:git-fetch[1]. See gitlink:git-fetch[1].

remote.<name>.push

The default set of "refspec" for gitlink:git-push[1]. See gitlink:git-push[1].

remote.<name>.skipDefaultUpdate

If true, this remote will be skipped by default when updating using the remote subcommand of gitlink:git-remote[1].

remote.<name>.receivepack

The default program to execute on the remote side when pushing. See option --exec of gitlink:git-push[1].

remote.<name>.uploadpack

The default program to execute on the remote side when fetching. See option --exec of gitlink:git-fetch-pack[1].

remote.<name>.tagopt

Setting this value to --no-tags disables automatic tag following when fetching from remote <name>

remotes.<group>

The list of remotes which are fetched by "git remote update <group>". See gitlink:git-remote[1].

repack.usedeltabaseoffset

Allow gitlink:git-repack[1] to create packs that uses delta-base offset. Defaults to false.

show.difftree

The default gitlink:git-diff-tree[1] arguments to be used for gitlink:git-show[1].

showbranch.default

The default set of branches for gitlink:git-show-branch[1]. See gitlink:git-show-branch[1].

tar.umask

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

user.email

Your email address to be recorded in any newly created commits. Can be overridden by the GIT_AUTHOR_EMAIL and GIT_COMMITTER_EMAIL environment variables. See gitlink:git-commit-tree[1].

user.name

Your full name to be recorded in any newly created commits. Can be overridden by the GIT_AUTHOR_NAME and GIT_COMMITTER_NAME environment variables. See gitlink:git-commit-tree[1].

user.signingkey

If gitlink:git-tag[1] is not selecting the key you want it to automatically when creating a signed tag, you can override the default selection with this variable. This option is passed unchanged to gpg’s --local-user parameter, so you may specify a key using any method that gpg supports.

whatchanged.difftree

The default gitlink:git-diff-tree[1] arguments to be used for gitlink:git-whatchanged[1].

imap

The configuration variables in the imap section are described in gitlink:git-imap-send[1].

receive.unpackLimit

If the number of objects received in a push is below this limit then the objects will be unpacked into loose object files. However if the number of received objects equals or exceeds this limit then the received pack will be stored as a pack, after adding any missing delta bases. Storing the pack from a push can make the push operation complete faster, especially on slow filesystems.

receive.denyNonFastForwards

If set to true, git-receive-pack will deny a ref update which is not a fast forward. Use this to prevent such an update via a push, even if that push is forced. This configuration variable is set when initializing a shared repository.

transfer.unpackLimit

When fetch.unpackLimit or receive.unpackLimit are not set, the value of this variable is used instead.
