=============

NAME
----
git-config - Get and set repository or global options


SYNOPSIS
--------
[verse]
'git-config' [--system | --global] name [value [value_regex]]
'git-config' [--system | --global] --add name value
'git-config' [--system | --global] --replace-all name [value [value_regex]]
'git-config' [--system | --global] [type] --get name [value_regex]
'git-config' [--system | --global] [type] --get-all name [value_regex]
'git-config' [--system | --global] --unset name [value_regex]
'git-config' [--system | --global] --unset-all name [value_regex]
'git-config' [--system | --global] --rename-section old_name new_name
'git-config' [--system | --global] --remove-section name
'git-config' [--system | --global] -l | --list

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).  Type specifiers currently only
take effect for reading operations.  If no type specifier is passed,
no checks or transformations are performed on the value.

This command will fail if:

. The .git/config file is invalid,
. Can not write to .git/config,
. no section was provided,
. the section or key is invalid,
. you try to unset an option which does not exist,
. you try to unset/set an option for which multiple lines match, or
. 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.

--system::
	Use system-wide $(prefix)/etc/gitconfig 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'
------------
