.SH "DESCRIPTION"
.sp
With no options and no \fI<command>\fR or \fI<doc>\fR given, the synopsis of the \fIgit\fR command and a list of the most commonly used Git commands are printed on the standard output\&.
.sp
If the option \fB\-\-all\fR or \fB\-a\fR is given, all available commands are printed on the standard output\&.
.sp
If the option \fB\-\-guides\fR or \fB\-g\fR is given, a list of the Git concept guides is also printed on the standard output\&.
.sp
If a command or other documentation is given, the relevant manual page will be brought up\&. The \fIman\fR program is used by default for this purpose, but this can be overridden by other options or configuration variables\&.
.sp
If an alias is given, git shows the definition of the alias on standard output\&. To get the manual page for the aliased command, use \fBgit\fR \fI<command>\fR \fB\-\-help\fR\&.
.sp
Note that \fBgit\fR \fB\-\-help\fR \&.\&.\&. is identical to \fBgit\fR \fBhelp\fR \&.\&.\&. because the former is internally converted into the latter\&.
.sp
To display the \fBgit\fR(1) man page, use \fBgit\fR \fBhelp\fR \fBgit\fR\&.
.sp
This page can be displayed with \fIgit help help\fR or \fBgit\fR \fBhelp\fR \fB\-\-help\fR\&.
.SH "OPTIONS"
.PP
\-a, \-\-all
.RS 4
Print all the available commands on the standard output\&.
.RE
.PP
\-\-no\-external\-commands
.RS 4
When used with
\fB\-\-all\fR, exclude the listing of external "git\-*" commands found in the
\fB$PATH\fR\&.
.RE
.PP
\-\-no\-aliases
.RS 4
When used with
\fB\-\-all\fR, exclude the listing of configured aliases\&.
.RE
.PP
\-\-verbose
.RS 4
When used with
\fB\-\-all\fR, print description for all recognized commands\&. This is the default\&.
.RE
.PP
\-c, \-\-config
.RS 4
List all available configuration variables\&. This is a short summary of the list in
\fBgit-config\fR(1)\&.
.RE
.PP
\-g, \-\-guides
.RS 4
Print a list of the Git concept guides on the standard output\&.
.RE
.PP
\-\-user\-interfaces
.RS 4
Print a list of the repository, command and file interfaces documentation on the standard output\&.
.sp
In\-repository file interfaces such as \&.\fBgit/info/exclude\fR
are documented here (see
\fBgitrepository-layout\fR(5)), as well as in\-tree configuration such as \&.\fBmailmap\fR
(see
\fBgitmailmap\fR(5))\&.
.sp
This section of the documentation also covers general or widespread user\-interface conventions (e\&.g\&.
\fBgitcli\fR(7)), and pseudo\-configuration such as the file\-based \&.\fBgit/hooks/\fR* interface described in
\fBgithooks\fR(5)\&.
.RE
.PP
\-\-developer\-interfaces
.RS 4
Print a list of file formats, protocols and other developer interfaces documentation on the standard output\&.
.RE
.PP
\-i, \-\-info
.RS 4
Display manual page for the command in the
\fIinfo\fR
format\&. The
\fIinfo\fR
program will be used for that purpose\&.
.RE
.PP
\-m, \-\-man
.RS 4
Display manual page for the command in the
\fIman\fR
format\&. This option may be used to override a value set in the
\fBhelp\&.format\fR
configuration variable\&.
.sp
By default the
\fIman\fR
program will be used to display the manual page, but the
\fBman\&.viewer\fR
configuration variable may be used to choose other display programs (see below)\&.
.RE
.PP
\-w, \-\-web
.RS 4
Display manual page for the command in the
\fIweb\fR
(HTML) format\&. A web browser will be used for that purpose\&.
.sp
The web browser can be specified using the configuration variable
\fBhelp\&.browser\fR, or
\fBweb\&.browser\fR
if the former is not set\&. If neither of these config variables is set, the
\fIgit web\-\-browse\fR
helper script (called by
\fIgit help\fR) will pick a suitable default\&. See
\fBgit-web--browse\fR(1)
for more information about this\&.
.RE
.SH "CONFIGURATION VARIABLES"
.SS "help\&.format"
.sp
If no command\-line option is passed, the \fBhelp\&.format\fR configuration variable will be checked\&. The following values are supported for this variable; they make \fIgit help\fR behave as their corresponding command\- line option:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
"man" corresponds to
\fI\-m|\-\-man\fR,
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
"info" corresponds to
\fI\-i|\-\-info\fR,
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
"web" or "html" correspond to
\fI\-w|\-\-web\fR\&.
.RE
.SS "help\&.browser, web\&.browser, and browser\&.<tool>\&.path"
.sp
The \fBhelp\&.browser\fR, \fBweb\&.browser\fR and \fBbrowser\&.\fR\fI<tool>\fR\fB\&.path\fR will also be checked if the \fIweb\fR format is chosen (either by command\-line option or configuration variable)\&. See \fI\-w|\-\-web\fR in the OPTIONS section above and \fBgit-web--browse\fR(1)\&.
.SS "man\&.viewer"
.sp
The \fBman\&.viewer\fR configuration variable will be checked if the \fIman\fR format is chosen\&. The following values are currently supported:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
"man": use the
\fIman\fR
program as usual,
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
"woman": use
\fIemacsclient\fR
to launch the "woman" mode in emacs (this only works starting with emacsclient versions 22),
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
"konqueror": use
\fIkfmclient\fR
to open the man page in a new konqueror tab (see
\fINote about konqueror\fR
below)\&.
.RE
.sp
Values for other tools can be used if there is a corresponding \fBman\&.\fR\fI<tool>\fR\fB\&.cmd\fR configuration entry (see below)\&.
.sp
Multiple values may be given to the \fBman\&.viewer\fR configuration variable\&. Their corresponding programs will be tried in the order listed in the configuration file\&.
.sp
For example, this configuration:
.sp
.if n \{\
.RS 4
.\}
.nf
        [man]
                viewer = konqueror
                viewer = woman
.fi
.if n \{\
.RE
.\}
.sp
will try to use konqueror first\&. But this may fail (for example, if DISPLAY is not set) and in that case emacs\*(Aq woman mode will be tried\&.
.sp
If everything fails, or if no viewer is configured, the viewer specified in the \fBGIT_MAN_VIEWER\fR environment variable will be tried\&. If that fails too, the \fIman\fR program will be tried anyway\&.
.SS "man\&.<tool>\&.path"
.sp
You can explicitly provide a full path to your preferred man viewer by setting the configuration variable \fBman\&.\fR\fI<tool>\fR\fB\&.path\fR\&. For example, you can configure the absolute path to konqueror by setting \fIman\&.konqueror\&.path\fR\&. Otherwise, \fIgit help\fR assumes the tool is available in PATH\&.
.SS "man\&.<tool>\&.cmd"
.sp
When the man viewer, specified by the \fBman\&.viewer\fR configuration variables, is not among the supported ones, then the corresponding \fBman\&.\fR\fI<tool>\fR\fB\&.cmd\fR 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\&.
.SS "Note about konqueror"
.sp
When \fIkonqueror\fR is specified in the \fBman\&.viewer\fR configuration variable, we launch \fIkfmclient\fR to try to open the man page on an already opened konqueror in a new tab if possible\&.
.sp
For consistency, we also try such a trick if \fIman\&.konqueror\&.path\fR is set to something like \fBA_PATH_TO/konqueror\fR\&. That means we will try to launch \fBA_PATH_TO/kfmclient\fR instead\&.
.sp
If you really want to use \fIkonqueror\fR, then you can use something like the following:
.sp
.if n \{\
.RS 4
.\}
.nf
        [man]
                viewer = konq
        [man "konq"]
                cmd = A_PATH_TO/konqueror
.fi
.if n \{\
.RE
.\}
.SS "Note about git config \-\-global"
.sp
Note that all these configuration variables should probably be set using the \fB\-\-global\fR flag, for example like this:
.sp
.if n \{\
.RS 4
.\}
.nf
$ git config \-\-global help\&.format web
$ git config \-\-global web\&.browser firefox
.fi
.if n \{\
.RE
.\}
.sp
as they are probably more user specific than repository specific\&. See \fBgit-config\fR(1) for more information about this\&.
