SYNOPSIS
|
|
|
|
|
--------
|
|
|
|
|
'git help' [-a|--all|-i|--info|-m|--man|-w|--web] [COMMAND]
|
|
|
|
|
|
|
|
|
|
DESCRIPTION
|
|
|
|
|
-----------
|
|
|
|
|
|
|
|
|
|
With no options and no COMMAND given, the synopsis of the 'git'
|
|
|
|
|
command and a list of the most commonly used git commands are printed
|
|
|
|
|
on the standard output.
|
|
|
|
|
|
|
|
|
|
If the option '--all' or '-a' is given, then all available commands are
|
|
|
|
|
printed on the standard output.
|
|
|
|
|
|
|
|
|
|
If a git command is named, a manual page for that command is brought
|
|
|
|
|
up. The 'man' program is used by default for this purpose, but this
|
|
|
|
|
can be overridden by other options or configuration variables.
|
|
|
|
|
|
|
|
|
|
Note that 'git --help ...' is identical as 'git help ...' because the
|
|
|
|
|
former is internally converted into the latter.
|
|
|
|
|
|
|
|
|
|
OPTIONS
|
|
|
|
|
-------
|
|
|
|
|
-a|--all::
|
|
|
|
|
Prints all the available commands on the standard output. This
|
|
|
|
|
option supersedes any other option.
|
|
|
|
|
|
|
|
|
|
-i|--info::
|
|
|
|
|
Display manual page for the command in the 'info' format. The
|
|
|
|
|
'info' program will be used for that purpose.
|
|
|
|
|
|
|
|
|
|
-m|--man::
|
|
|
|
|
Display manual page for the command in the 'man' format. This
|
|
|
|
|
option may be used to override a value set in the
|
|
|
|
|
'help.format' configuration variable.
|
|
|
|
|
+
|
|
|
|
|
By default the 'man' program will be used to display the manual page,
|
|
|
|
|
but the 'man.viewer' configuration variable may be used to choose
|
|
|
|
|
other display programs (see below).
|
|
|
|
|
|
|
|
|
|
-w|--web::
|
|
|
|
|
Display manual page for the command in the 'web' (HTML)
|
|
|
|
|
format. A web browser will be used for that purpose.
|
|
|
|
|
+
|
|
|
|
|
The web browser can be specified using the configuration variable
|
|
|
|
|
'help.browser', or 'web.browser' if the former is not set. If none of
|
|
|
|
|
these config variables is set, the 'git-web--browse' helper script
|
|
|
|
|
(called by 'git-help') will pick a suitable default. See
|
|
|
|
|
linkgit:git-web--browse[1] for more information about this.
|
|
|

CONFIGURATION VARIABLES
|
|
|
|
|
-----------------------
|
|
|
|
|
|
|
|
|
|
help.format
|
|
|
|
|
~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
If no command line option is passed, the 'help.format' configuration
|
|
|
|
|
variable will be checked. The following values are supported for this
|
|
|
|
|
variable; they make 'git-help' behave as their corresponding command
|
|
|
|
|
line option:
|
|
|
|
|
|
|
|
|
|
* "man" corresponds to '-m|--man',
|
|
|
|
|
* "info" corresponds to '-i|--info',
|
|
|
|
|
* "web" or "html" correspond to '-w|--web'.
|
|
|
|
|
|
|
|
|
|
help.browser, web.browser and browser.<tool>.path
|
|
|
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
The 'help.browser', 'web.browser' and 'browser.<tool>.path' will also
|
|
|
|
|
be checked if the 'web' format is chosen (either by command line
|
|
|
|
|
option or configuration variable). See '-w|--web' in the OPTIONS
|
|
|
|
|
section above and linkgit:git-web--browse[1].
|
|
|
|
|
|
|
|
|
|
man.viewer
|
|
|
|
|
~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
The 'man.viewer' config variable will be checked if the 'man' format
|
|
|
|
|
is chosen. Only the following values are currently supported:
|
|
|
|
|
|
|
|
|
|
* "man": use the 'man' program as usual,
|
|
|
|
|
* "woman": use 'emacsclient' to launch the "woman" mode in emacs
|
|
|
|
|
(this only works starting with emacsclient versions 22),
|
|
|
|
|
* "konqueror": use a man KIO slave in konqueror.
|
|
|
|
|
|
|
|
|
|
Multiple values may be given to this configuration variable. Their
|
|
|
|
|
corresponding programs will be tried in the order listed in the
|
|
|
|
|
configuration file.
|
|
|
|
|
|
|
|
|
|
For example, this configuration:
|
|
|
|
|
|
|
|
|
|
[man]
|
|
|
|
|
viewer = konqueror
|
|
|
|
|
viewer = woman
|
|
|
|
|
|
|
|
|
|
will try to use konqueror first. But this may fail (for example if
|
|
|
|
|
DISPLAY is not set) and in that case emacs' woman mode will be tried.
|
|
|
|
|
|
|
|
|
|
If everything fails the 'man' program will be tried anyway.
|
|
|
|
|
|
|
|
|
|
Note about git config --global
|
|
|
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
|
|
|
|
|
|
Note that all these configuration variables should probably be set
|
|
|
|
|
using the '--global' flag, for example like this:
|
|
|
|
|
|
|
|
|
|
------------------------------------------------
|
|
|
|
|
$ git config --global help.format web
|
|
|
|
|
$ git config --global web.browser firefox
|
|
|
|
|
------------------------------------------------
|
|
|
|
|
|
|
|
|
|
as they are probably more user specific than repository specific.
|
|
|
|
