git-config(1)

NAME

git-config - Get and set repository or global options

SYNOPSIS

git config list [<file-option>] [<display-option>] [--includes]
git config get [<file-option>] [<display-option>] [--includes] [--all] [--regexp] [--value=<value>] [--fixed-value] [--default=<default>] <name>
git config set [<file-option>] [--type=<type>] [--all] [--value=<value>] [--fixed-value] <name> <value>
git config unset [<file-option>] [--all] [--value=<value>] [--fixed-value] <name>
git config rename-section [<file-option>] <old-name> <new-name>
git config remove-section [<file-option>] <name>
git config edit [<file-option>]
git config [<file-option>] --get-colorbool <name> [<stdout-is-tty>]

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 --append option. If you want to update or unset an option which can occur on multiple lines, a value-pattern (which is an extended regular expression, unless the --fixed-value option is given) needs to be given. Only the existing values that match the pattern are updated or unset. If you want to handle the lines that do not match the pattern, just prepend a single exclamation mark in front (see also EXAMPLES), but note that this only works when the --fixed-value option is not in use.

The --type=<type> option instructs git config to ensure that incoming and outgoing values are canonicalize-able under the given <type>. If no --type=<type> is given, no canonicalization will be performed. Callers may unset an existing --type specifier with --no-type.

When reading, the values are read from the system, global and repository local configuration files by default, and options --system, --global, --local, --worktree and --file <filename> can be used to tell the command to read from only that location (see FILES).

When writing, the new value is written to the repository local configuration file by default, and options --system, --global, --worktree, --file <filename> can be used to tell the command to write to that location (you can say --local but that is the default).

This command will fail with non-zero status upon error. Some exit codes are:

The section or key is invalid (ret=1),
no section or name was provided (ret=2),
the config file is invalid (ret=3),
the config file cannot be written (ret=4),
you try to unset an option which does not exist (ret=5),
you try to unset/set an option for which multiple lines match (ret=5), or
you try to use an invalid regexp (ret=6).

On success, the command returns the exit code 0.

A list of all available configuration variables can be obtained using the git help --config command.

COMMANDS

list: List all variables set in config file, along with their values.
get: Emits the value of the specified key. If key is present multiple times in the configuration, emits the last value. If --all is specified, emits all values associated with key. Returns error code 1 if key is not present.
set: Set value for one or more config options. By default, this command refuses to write multi-valued config options. Passing --all will replace all multi-valued config options with the new value, whereas --value= will replace all config options whose values match the given pattern.
unset: Unset value for one or more config options. By default, this command refuses to unset multi-valued keys. Passing --all will unset all multi-valued config options, whereas --value will unset all config options whose values match the given pattern.
rename-section: Rename the given section to a new name.
remove-section: Remove the given section from the configuration file.
edit: Opens an editor to modify the specified config file; either --system, --global, --local (default), --worktree, or --file <config-file>.

OPTIONS

--replace-all

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

--append

Adds a new line to the option without altering any existing values. This is the same as providing --value=^$ in set.

--comment <message>

Append a comment at the end of new or modified lines.

If _<message>_ begins with one or more whitespaces followed
by "#", it is used as-is.  If it begins with "#", a space is
prepended before it is used.  Otherwise, a string " # " (a
space followed by a hash followed by a space) is prepended
to it.  And the resulting string is placed immediately after
the value defined for the variable.  The _<message>_ must
not contain linefeed characters (no multi-line comments are
permitted).

--all

With get, return all values for a multi-valued key.

--regexp

With get, interpret the name as a regular expression. Regular expression matching is currently case-sensitive and done against a canonicalized version of the key in which section and variable names are lowercased, but subsection names are not.

--url=<URL>

When given a two-part <name> as <section>.<key>, the value for <section>.<URL>.<key> whose <URL> part matches the best to the given URL is returned (if no such key exists, the value for <section>.<key> is used as a fallback). When given just the <section> as name, do so for all the keys in the section and list them. Returns error code 1 if no value is found.

--global

For writing options: write to global ~/.gitconfig file rather than the repository .git/config, write to $XDG_CONFIG_HOME/git/config file if this file exists and the ~/.gitconfig file doesn’t.

For reading options: read only from global ~/.gitconfig and from $XDG_CONFIG_HOME/git/config rather than from all available files.

See also FILES.

--system

For writing options: write to system-wide $(prefix)/etc/gitconfig rather than the repository .git/config.

For reading options: read only from system-wide $(prefix)/etc/gitconfig rather than from all available files.

See also FILES.

--local

For writing options: write to the repository .git/config file. This is the default behavior.

For reading options: read only from the repository .git/config rather than from all available files.

See also FILES.

--worktree

Similar to --local except that $GIT_DIR/config.worktree is read from or written to if extensions.worktreeConfig is enabled. If not it’s the same as --local. Note that $GIT_DIR is equal to $GIT_COMMON_DIR for the main working tree, but is of the form $GIT_DIR/worktrees/<id>/ for other working trees. See linkgit:git-worktree[1] to learn how to enable extensions.worktreeConfig.

-f <config-file>

--file <config-file>

For writing options: write to the specified file rather than the repository .git/config.

For reading options: read only from the specified file rather than from all available files.

See also FILES.

--blob <blob>

Similar to --file but use the given blob instead of a file. E.g. you can use master:.gitmodules to read values from the file .gitmodules in the master branch. See "SPECIFYING REVISIONS" section in linkgit:gitrevisions[7] for a more complete list of ways to spell blob names.

--fixed-value

When used with the value-pattern argument, treat value-pattern as an exact string instead of a regular expression. This will restrict the name/value pairs that are matched to only those where the value is exactly equal to the value-pattern.

--type <type>

git config will ensure that any input or output is valid under the given type constraint(s), and will canonicalize outgoing values in <type>'s canonical form.

Valid <type>'s include:

bool: canonicalize values true, yes,on, and positive numbers as "true", and values false, no, off and 0 as "false".
int: canonicalize values as simple decimal numbers. An optional suffix of k, m, or g will cause the value to be multiplied by 1024, 1048576, or 1073741824 upon input.
bool-or-int: canonicalize according to either bool or int, as described above.
path: canonicalize by expanding a leading ~ to the value of $HOME and ~user to the home directory for the specified user. This specifier has no effect when setting the value (but you can use git config section.variable ~/ from the command line to let your shell do the expansion.)
expiry-date: canonicalize by converting from a fixed or relative date-string to a timestamp. This specifier has no effect when setting the value.
color: When getting a value, canonicalize by converting to an ANSI color escape sequence. When setting a value, a sanity-check is performed to ensure that the given value is canonicalize-able as an ANSI color, but it is written as-is.

--bool

--int

--bool-or-int

--path

--expiry-date

Historical options for selecting a type specifier. Prefer instead --type (see above).

--no-type

Un-sets the previously set type specifier (if one was previously set). This option requests that git config not canonicalize the retrieved variable. --no-type has no effect without --type=<type> or --<type>.

-z

--null

For all options that output values and/or keys, always end values with the null character (instead of a newline). Use newline instead as a delimiter between key and value. This allows for secure parsing of the output without getting confused e.g. by values that contain line breaks.

--name-only

Output only the names of config variables for list or get.

--show-origin

Augment the output of all queried config options with the origin type (file, standard input, blob, command line) and the actual origin (config file path, ref, or blob id if applicable).

--show-scope

Similar to --show-origin in that it augments the output of all queried config options with the scope of that value (worktree, local, global, system, command).

--get-colorbool <name> [<stdout-is-tty>]

Find the color setting for <name> (e.g. color.diff) and output "true" or "false". <stdout-is-tty> should be either "true" or "false", and is taken into account when configuration says "auto". If <stdout-is-tty> is missing, then checks the standard output of the command itself, and exits with status 0 if color is to be used, or exits with status 1 otherwise. When the color setting for name is undefined, the command uses color.ui as fallback.

--[no-]includes

Respect include.* directives in config files when looking up values. Defaults to off when a specific file is given (e.g., using --file, --global, etc) and on when searching all config files.

--default <value>

When using get, and the requested variable is not found, behave as if <value> were the value assigned to that variable.

DEPRECATED MODES

The following modes have been deprecated in favor of subcommands. It is recommended to migrate to the new syntax.

git config <name> <value> [<value-pattern>]: Replaced by git config set [--value=<pattern>] <name> <value>.
-l
--list: Replaced by git config list.
--get <name> [<value-pattern>]: Replaced by git config get [--value=<pattern>] <name>.
--get-all <name> [<value-pattern>]: Replaced by git config get [--value=<pattern>] --all <name>.
--get-regexp <name-regexp>: Replaced by git config get --all --show-names --regexp <name-regexp>.
--get-urlmatch <name> <URL>: Replaced by git config get --all --show-names --url=<URL> <name>.
--get-color <name> [<default>]: Replaced by git config get --type=color [--default=<default>] <name>.
--add <name> <value>: Replaced by git config set --append <name> <value>.
--unset <name> [<value-pattern>]: Replaced by git config unset [--value=<pattern>] <name>.
--unset-all <name> [<value-pattern>]: Replaced by git config unset [--value=<pattern>] --all <name>.
--rename-section <old-name> <new-name>: Replaced by git config rename-section <old-name> <new-name>.
--remove-section <name>: Replaced by git config remove-section <name>.
-e
--edit: Replaced by git config edit.

CONFIGURATION

pager.config is only respected when listing configuration, i.e., when using list or get which may return multiple results. The default is to use a pager.

FILES

By default, git config will read configuration options from multiple files:

$(prefix)/etc/gitconfig: System-wide configuration file.
$XDG_CONFIG_HOME/git/config
~/.gitconfig: User-specific configuration files. When the XDG_CONFIG_HOME environment variable is not set or empty, $HOME/.config/ is used as $XDG_CONFIG_HOME.

These are also called "global" configuration files. If both files exist, both files are read in the order given above.
$GIT_DIR/config: Repository specific configuration file.
$GIT_DIR/config.worktree: This is optional and is only searched when extensions.worktreeConfig is present in $GIT_DIR/config.

You may also provide additional configuration parameters when running any git command by using the -c option. See linkgit:git[1] for details.

Options will be read from all of these files that are available. If the global or the system-wide configuration files are missing or unreadable they will be ignored. If the repository configuration file is missing or unreadable, git config will exit with a non-zero error code. An error message is produced if the file is unreadable, but not if it is missing.

The files are read in the order given above, with last value found taking precedence over values read earlier. When multiple values are taken then all values of a key from all files will be used.

By default, options are only written to the repository specific configuration file. Note that this also affects options like set and unset. git config will only ever change one file at a time.

You can limit which configuration sources are read from or written to by specifying the path of a file with the --file option, or by specifying a configuration scope with --system, --global, --local, or --worktree. For more, see OPTIONS above.

SCOPES

Each configuration source falls within a configuration scope. The scopes are:

system: $(prefix)/etc/gitconfig
global: $XDG_CONFIG_HOME/git/config

~/.gitconfig
local: $GIT_DIR/config
worktree: $GIT_DIR/config.worktree
command: GIT_CONFIG_{COUNT,KEY,VALUE} environment variables (see ENVIRONMENT below)

the -c option

With the exception of command, each scope corresponds to a command line option: --system, --global, --local, --worktree.

When reading options, specifying a scope will only read options from the files within that scope. When writing options, specifying a scope will write to the files within that scope (instead of the repository specific configuration file). See OPTIONS above for a complete description.

Most configuration options are respected regardless of the scope it is defined in, but some options are only respected in certain scopes. See the respective option’s documentation for the full details.

Protected configuration

Protected configuration refers to the system, global, and command scopes. For security reasons, certain options are only respected when they are specified in protected configuration, and ignored otherwise.

Git treats these scopes as if they are controlled by the user or a trusted administrator. This is because an attacker who controls these scopes can do substantial harm without using Git, so it is assumed that the user’s environment protects these scopes against attackers.

ENVIRONMENT

GIT_CONFIG_GLOBAL
GIT_CONFIG_SYSTEM: Take the configuration from the given files instead from global or system-level configuration. See linkgit:git[1] for details.
GIT_CONFIG_NOSYSTEM: Whether to skip reading settings from the system-wide $(prefix)/etc/gitconfig file. See linkgit:git[1] for details.

See also FILES.

GIT_CONFIG_COUNT
GIT_CONFIG_KEY_<n>
GIT_CONFIG_VALUE_<n>: If GIT_CONFIG_COUNT is set to a positive number, all environment pairs GIT_CONFIG_KEY_<n> and GIT_CONFIG_VALUE_<n> up to that number will be added to the process’s runtime configuration. The config pairs are zero-indexed. Any missing key or value is treated as an error. An empty GIT_CONFIG_COUNT is treated the same as GIT_CONFIG_COUNT=0, namely no pairs are processed. These environment variables will override values in configuration files, but will be overridden by any explicit options passed via git -c.

This is useful for cases where you want to spawn multiple git commands with a common configuration but cannot depend on a configuration file, for example when writing scripts.
GIT_CONFIG: If no --file option is provided to git config, use the file given by GIT_CONFIG as if it were provided via --file. This variable has no effect on other Git commands, and is mostly for historical compatibility; there is generally no reason to use it instead of the --file option.

EXAMPLES

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/diff-wrapper
	renames = true

; Proxy settings
[core]
	gitproxy=proxy-command for kernel.org
	gitproxy=default-proxy ; for all the rest

; HTTP
[http]
	sslVerify
[http "https://weak.example.com"]
	sslVerify = false
	cookieFile = /tmp/cookie.txt

you can set the filemode to true with

% git config set 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 set --value='for kernel.org$' core.gitproxy '"ssh" 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, to query a multivar:

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

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

% git config get --all --show-names core.gitproxy

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

% git config set --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 set --value='! for ' core.gitproxy ssh

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

% git config set --value='[!]' section.key value

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

% git config set --append core.gitproxy '"proxy-command" for example.com'

An example to use customized color from the configuration in your script:

#!/bin/sh
WS=$(git config get --type=color --default="blue reverse" color.diff.whitespace)
RESET=$(git config get --type=color --default="reset" "")
echo "${WS}your whitespace color or blue reverse${RESET}"

For URLs in https://weak.example.com, http.sslVerify is set to false, while it is set to true for all others:

% git config get --type=bool --url=https://good.example.com http.sslverify
true
% git config get --type=bool --url=https://weak.example.com http.sslverify
false
% git config get --url=https://weak.example.com http
http.cookieFile /tmp/cookie.txt
http.sslverify false

role=include

BUGS

When using the deprecated [section.subsection] syntax, changing a value will result in adding a multi-line key instead of a change, if the subsection is given with at least one uppercase character. For example when the config looks like

  [section.subsection]
    key = value1

and running git config section.Subsection.key value2 will result in

  [section.subsection]
    key = value1
    key = value2
