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are out of date and incomplete.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wanted to cc the contact point, the out-of-date and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.

NAME
|
|
----
|
|
git-help - display help information about git
|
|
|
|
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 to `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{litdd}browse' helper script
|
|
(called by 'git help') will pick a suitable default. See
|
|
linkgit:git-web{litdd}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{litdd}browse[1].
|
|
|
|
man.viewer
|
|
~~~~~~~~~~
|
|
|
|
The 'man.viewer' config variable will be checked if the 'man' format
|
|
is chosen. 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 'kfmclient' to open the man page in a new konqueror
|
|
tab (see 'Note about konqueror' below).
|
|
|
|
Values for other tools can be used if there is a corresponding
|
|
'man.<tool>.cmd' configuration entry (see below).
|
|
|
|
Multiple values may be given to the 'man.viewer' 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, or if no viewer is configured, the viewer specified
|
|
in the GIT_MAN_VIEWER environment variable will be tried. If that
|
|
fails too, the 'man' program will be tried anyway.
|
|
|
|
man.<tool>.path
|
|
~~~~~~~~~~~~~~~
|
|
|
|
You can explicitly provide a full path to your preferred man viewer by
|
|
setting the configuration variable 'man.<tool>.path'. For example, you
|
|
can configure the absolute path to konqueror by setting
|
|
'man.konqueror.path'. Otherwise, 'git help' assumes the tool is
|
|
available in PATH.
|
|
|
|
man.<tool>.cmd
|
|
~~~~~~~~~~~~~~
|
|
|
|
When the man viewer, specified by the 'man.viewer' configuration
|
|
variables, is not among the supported ones, then the corresponding
|
|
'man.<tool>.cmd' configuration variable will be looked up. If this
|
|
variable exists then the specified tool will be treated as a custom
|
|
command and a shell eval will be used to run the command with the man
|
|
page passed as arguments.
|
|
|
|
Note about konqueror
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
When 'konqueror' is specified in the 'man.viewer' configuration
|
|
variable, we launch 'kfmclient' to try to open the man page on an
|
|
already opened konqueror in a new tab if possible.
|
|
|
|
For consistency, we also try such a trick if 'man.konqueror.path' is
|
|
set to something like 'A_PATH_TO/konqueror'. That means we will try to
|
|
launch 'A_PATH_TO/kfmclient' instead.
|
|
|
|
If you really want to use 'konqueror', then you can use something like
|
|
the following:
|
|
|
|
------------------------------------------------
|
|
[man]
|
|
viewer = konq
|
|
|
|
[man "konq"]
|
|
cmd = A_PATH_TO/konqueror
|
|
------------------------------------------------
|
|
|
|
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.
|
|
