git-config-set(1)
===============

NAME
----
git-config-set - Set options in .git/config.


SYNOPSIS
--------
'git-config-set' name [value [value_regex]]
'git-config-set' --replace-all name [value [value_regex]]
'git-config-set' --get name [value_regex]
'git-config-set' --get-all name [value_regex]
'git-config-set' --unset name [value_regex]
'git-config-set' --unset-all name [value_regex]

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.

If you want to set/unset an option which can occor on multiple lines, you
should provide a POSIX regex for the value. If you want to handle the lines
*not* matching the regex, just prepend a single exlamation mark in front
(see EXAMPLES).

This command will fail if

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


OPTIONS
-------

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

--get::
	Get the value for a given key (optionally filtered by a regex
	matching the value).

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

--unset::
	Remove the line matching the key from .git/config.

--unset-all::
	Remove all matching lines from .git/config.


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
	[proxy]
		command="ssh" for "ssh://kernel.org/"
		command="proxy-command" for kernel.org
		command="myprotocol-command" for "my://"
		command=default-proxy ; for all the rest

you can set the filemode to true with

------------
% git config-set core.filemode true
------------

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

------------
% git config-set proxy.command '"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-set --unset diff.renames
------------

If you want to delete an entry for a multivar (like proxy.command 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-set --get core.filemode
------------

or

------------
% git config-set core.filemode
------------

or, to query a multivar:

------------
% git config-set --get proxy.command "for kernel.org$"
------------

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

------------
% git config-set --get-all proxy.command
------------

If you like to live dangerous, you can replace *all* proxy.commands by a
new one with

------------
% git config-set --replace-all proxy.command 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 proxy.command ssh '! for '
------------

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

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