# git-help(1) Manual Page

## NAME

git-help - Display help information about Git

## SYNOPSIS

    git help [-a|--all] [--[no-]verbose] [--[no-]external-commands] [--[no-]aliases]
    git help [[-i|--info] [-m|--man] [-w|--web]] [<command>|<doc>]
    git help [-g|--guides]
    git help [-c|--config]
    git help [--user-interfaces]
    git help [--developer-interfaces]

## DESCRIPTION

With no options and no <command> or <doc> 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, all available commands are printed on the standard output.

If the option `--guides` or `-g` is given, a list of the Git concept guides is also printed on the standard output.

If a command or other documentation is given, the relevant manual page will be brought up. The man program is used by default for this purpose, but this can be overridden by other options or configuration variables.

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 `git <command> --help`.

Note that `git --help ...` is identical to `git help ...` because the former is internally converted into the latter.

To display the git(1) man page, use `git help git`.

This page can be displayed with git help help or `git help --help`

## OPTIONS

-a
--all

  Prints all the available commands on the standard output.

--no-external-commands

  When used with `--all`, exclude the listing of external "git-*" commands found in the `$PATH`.

--no-aliases

  When used with `--all`, exclude the listing of configured aliases.

--verbose

  When used with `--all` print description for all recognized commands. This is the default.

-c
--config

  List all available configuration variables. This is a short summary of the list in git-config(1).

-g
--guides

  Prints a list of the Git concept guides on the standard output.

--user-interfaces

  Prints a list of the repository, command and file interfaces documentation on the standard output.

  In-repository file interfaces such as `.git/info/exclude` are documented here (see gitrepository-layout(5)), as well as in-tree configuration such as `.mailmap` (see gitmailmap(5)).

  This section of the documentation also covers general or widespread user-interface conventions (e.g. gitcli(7)), and pseudo-configuration such as the file-based `.git/hooks/*` interface described in githooks(5).

--developer-interfaces

  Print list of file formats, protocols and other developer interfaces documentation on the standard output.

-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 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 git-web--browse(1).

### man.viewer

The `man.viewer` configuration 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. See git-config(1) for more information about this.
