The point of these sections is generally to:
1. Give credit where it is due.
2. Give the reader an idea of where to ask questions or
file bug reports.
But they don't do a good job of either case. For (1), they
are out of date and incomplete. A much more accurate answer
can be gotten through shortlog or blame. For (2), the
correct contact point is generally git@vger, and even if you
wanted to cc the contact point, the out-of-date and
incomplete fields mean you're likely sending to somebody
useless.
So let's drop the fields entirely from all manpages except
git(1) itself. We already point people to the mailing list
for bug reports there, and we can update the Authors section
to give credit to the major contributors and point to
shortlog and blame for more information.
Each page has a "This is part of git" footer, so people can
follow that to the main git manpage.

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 also <<EXAMPLES>>).
|
|
|
|
The type specifier can be either '--int' or '--bool', to 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), or '--path', which does some
|
|
path expansion (see '--path' below). If no type specifier is passed, no
|
|
checks or transformations are performed on the value.
|
|
|
|
The file-option can be one of '--system', '--global' or '--file'
|
|
which specify where the values will be read from or written to.
|
|
The default is to assume the config file of the current repository,
|
|
.git/config unless defined otherwise with GIT_DIR and GIT_CONFIG
|
|
(see <<FILES>>).
|
|
|
|
This command will fail if:
|
|
|
|
. The config file is invalid,
|
|
. Can not write to the config file,
|
|
. 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
|
|
in `--replace-all`.
|
|
|
|
--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.
|
|
Also outputs the key names.
|
|
|
|
--global::
|
|
For writing options: write to global ~/.gitconfig file rather than
|
|
the repository .git/config.
|
|
+
|
|
For reading options: read only from global ~/.gitconfig 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 $(prefix)/etc/gitconfig
|
|
rather than from all available files.
|
|
+
|
|
See also <<FILES>>.
|
|
|
|
-f config-file::
|
|
--file config-file::
|
|
Use the given config file instead of the one specified by GIT_CONFIG.
|
|
|
|
--remove-section::
|
|
Remove the given section from the configuration file.
|
|
|
|
--rename-section::
|
|
Rename the given section to a new name.
|
|
|
|
--unset::
|
|
Remove the line matching the key from config file.
|
|
|
|
--unset-all::
|
|
Remove all lines matching the key from config file.
|
|
|
|
-l::
|
|
--list::
|
|
List all variables set in config file.
|
|
|
|
--bool::
|
|
'git config' will ensure that the output is "true" or "false"
|
|
|
|
--int::
|
|
'git config' will ensure that the output is a simple
|
|
decimal number. An optional value suffix of 'k', 'm', or 'g'
|
|
in the config file will cause the value to be multiplied
|
|
by 1024, 1048576, or 1073741824 prior to output.
|
|
|
|
--bool-or-int::
|
|
'git config' will ensure that the output matches the format of
|
|
either --bool or --int, as described above.
|
|
|
|
--path::
|
|
'git-config' will expand leading '{tilde}' to the value of
|
|
'$HOME', and '{tilde}user' to the home directory for the
|
|
specified user. This option has no effect when setting the
|
|
value (but you can use 'git config bla {tilde}/' from the
|
|
command line to let your shell do the expansion).
|
|
|
|
-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.
|
|
|
|
--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.
|
|
|
|
--get-color name [default]::
|
|
|
|
Find the color configured for `name` (e.g. `color.diff.new`) and
|
|
output it as the ANSI color escape sequence to the standard
|
|
output. The optional `default` parameter is used instead, if
|
|
there is no color configured for `name`.
|
|
|
|
-e::
|
|
--edit::
|
|
Opens an editor to modify the specified config file; either
|
|
'--system', '--global', or repository (default).
|
|
|
|
[[FILES]]
|
|
FILES
|
|
-----
|
|
|
|
If not set explicitly with '--file', there are three files where
|
|
'git config' will search for configuration options:
|
|
|
|
$GIT_DIR/config::
|
|
Repository specific configuration file. (The filename is
|
|
of course relative to the repository root, not the working
|
|
directory.)
|
|
|
|
~/.gitconfig::
|
|
User-specific configuration file. Also called "global"
|
|
configuration file.
|
|
|
|
$(prefix)/etc/gitconfig::
|
|
System-wide configuration file.
|
|
|
|
If no further options are given, all reading options will read all of these
|
|
files that are available. If the global or the system-wide configuration
|
|
file are not available they will be ignored. If the repository configuration
|
|
file is not available or readable, 'git config' will exit with a non-zero
|
|
error code. However, in neither case will an error message be issued.
|
|
|
|
All writing options will per default write to the repository specific
|
|
configuration file. Note that this also affects options like '--replace-all'
|
|
and '--unset'. *'git config' will only ever change one file at a time*.
|
|
|
|
You can override these rules either by command line options or by environment
|
|
variables. The '--global' and the '--system' options will limit the file used
|
|
to the global or system-wide file respectively. The GIT_CONFIG environment
|
|
variable has a similar effect, but you can specify any filename you want.
|
|
|
|
|
|
ENVIRONMENT
|
|
-----------
|
|
|
|
GIT_CONFIG::
|
|
Take the configuration from the given file instead of .git/config.
|
|
Using the "--global" option forces this to ~/.gitconfig. Using the
|
|
"--system" option forces this to $(prefix)/etc/gitconfig.
|
|
|
|
See also <<FILES>>.

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
|
|
|
|
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 dangerously, 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-command" for example.com'
|
|
------------
|
|
|
|
An example to use customized color from the configuration in your
|
|
script:
|
|
|
|
------------
|
|
#!/bin/sh
|
|
WS=$(git config --get-color color.diff.whitespace "blue reverse")
|
|
RESET=$(git config --get-color "" "reset")
|
|
echo "${WS}your whitespace color or blue reverse${RESET}"
