   8SYNOPSIS
   9--------
  10'git help' [-a|--all|-i|--info|-m|--man|-w|--web] [COMMAND]
  11
  12DESCRIPTION
  13-----------
  14
  15With no options and no COMMAND given, the synopsis of the 'git'
  16command and a list of the most commonly used git commands are printed
  17on the standard output.
  18
  19If the option '--all' or '-a' is given, then all available commands are
  20printed on the standard output.
  21
  22If a git command is named, a manual page for that command is brought
  23up. The 'man' program is used by default for this purpose, but this
  24can be overridden by other options or configuration variables.
  25
  26Note that `git --help ...` is identical to `git help ...` because the
  27former is internally converted into the latter.
  28
  29OPTIONS
  30-------
  31-a::
  32--all::
  33        Prints all the available commands on the standard output. This
  34        option supersedes any other option.
  35
  36-i::
  37--info::
  38        Display manual page for the command in the 'info' format. The
  39        'info' program will be used for that purpose.
  40
  41-m::
  42--man::
  43        Display manual page for the command in the 'man' format. This
  44        option may be used to override a value set in the
  45        'help.format' configuration variable.
  46+
  47By default the 'man' program will be used to display the manual page,
  48but the 'man.viewer' configuration variable may be used to choose
  49other display programs (see below).
  50
  51-w::
  52--web::
  53        Display manual page for the command in the 'web' (HTML)
  54        format. A web browser will be used for that purpose.
  55+
  56The web browser can be specified using the configuration variable
  57'help.browser', or 'web.browser' if the former is not set. If none of
  58these config variables is set, the 'git-web--browse' helper script
  59(called by 'git-help') will pick a suitable default. See
  60linkgit:git-web--browse[1] for more information about this.
  61
  62CONFIGURATION VARIABLES
  63-----------------------
  64
  65help.format
  66~~~~~~~~~~~
  67
  68If no command line option is passed, the 'help.format' configuration
  69variable will be checked. The following values are supported for this
  70variable; they make 'git-help' behave as their corresponding command
  71line option:
  72
  73* "man" corresponds to '-m|--man',
  74* "info" corresponds to '-i|--info',
  75* "web" or "html" correspond to '-w|--web'.
  76
  77help.browser, web.browser and browser.<tool>.path
  78~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  79
  80The 'help.browser', 'web.browser' and 'browser.<tool>.path' will also
  81be checked if the 'web' format is chosen (either by command line
  82option or configuration variable). See '-w|--web' in the OPTIONS
  83section above and linkgit:git-web--browse[1].
  84
  85man.viewer
  86~~~~~~~~~~
  87
  88The 'man.viewer' config variable will be checked if the 'man' format
  89is chosen. The following values are currently supported:
  90
  91* "man": use the 'man' program as usual,
  92* "woman": use 'emacsclient' to launch the "woman" mode in emacs
  93(this only works starting with emacsclient versions 22),
  94* "konqueror": use 'kfmclient' to open the man page in a new konqueror
  95tab (see 'Note about konqueror' below).
  96
  97Values for other tools can be used if there is a corresponding
  98'man.<tool>.cmd' configuration entry (see below).
  99
 100Multiple values may be given to the 'man.viewer' configuration
 101variable. Their corresponding programs will be tried in the order
 102listed in the configuration file.
 103
 104For example, this configuration:
 105
 106------------------------------------------------
 107        [man]
 108                viewer = konqueror
 109                viewer = woman
 110------------------------------------------------
 111
 112will try to use konqueror first. But this may fail (for example if
 113DISPLAY is not set) and in that case emacs' woman mode will be tried.
 114
 115If everything fails the 'man' program will be tried anyway.
 116
 117man.<tool>.path
 118~~~~~~~~~~~~~~~
 119
 120You can explicitly provide a full path to your preferred man viewer by
 121setting the configuration variable 'man.<tool>.path'. For example, you
 122can configure the absolute path to konqueror by setting
 123'man.konqueror.path'. Otherwise, 'git-help' assumes the tool is
 124available in PATH.
 125
 126man.<tool>.cmd
 127~~~~~~~~~~~~~~
 128
 129When the man viewer, specified by the 'man.viewer' configuration
 130variables, is not among the supported ones, then the corresponding
 131'man.<tool>.cmd' configuration variable will be looked up. If this
 132variable exists then the specified tool will be treated as a custom
 133command and a shell eval will be used to run the command with the man
 134page passed as arguments.
 135
 136Note about konqueror
 137~~~~~~~~~~~~~~~~~~~~
 138
 139When 'konqueror' is specified in the 'man.viewer' configuration
 140variable, we launch 'kfmclient' to try to open the man page on an
 141already opened konqueror in a new tab if possible.
 142
 143For consistency, we also try such a trick if 'man.konqueror.path' is
 144set to something like 'A_PATH_TO/konqueror'. That means we will try to
 145launch 'A_PATH_TO/kfmclient' instead.
 146
 147If you really want to use 'konqueror', then you can use something like
 148the following:
 149
 150------------------------------------------------
 151        [man]
 152                viewer = konq
 153
 154        [man "konq"]
 155                cmd = A_PATH_TO/konqueror
 156------------------------------------------------
 157
 158Note about git config --global
 159~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 160
 161Note that all these configuration variables should probably be set
 162using the '--global' flag, for example like this:
 163
 164------------------------------------------------
 165$ git config --global help.format web
 166$ git config --global web.browser firefox
 167------------------------------------------------
 168
 169as they are probably more user specific than repository specific.
 170See linkgit:git-config[1] for more information about this.
