   6git-help - display help information about git

   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 as 'git help ...' because the
  27former is internally converted into the latter.
  28
  29OPTIONS
  30-------
  31-a|--all::
  32        Prints all the available commands on the standard output. This
  33        option supersedes any other option.
  34
  35-i|--info::
  36        Display manual page for the command in the 'info' format. The
  37        'info' program will be used for that purpose.
  38
  39-m|--man::
  40        Display manual page for the command in the 'man' format. This
  41        option may be used to override a value set in the
  42        'help.format' configuration variable.
  43+
  44By default the 'man' program will be used to display the manual page,
  45but the 'man.viewer' configuration variable may be used to choose
  46other display programs (see below).
  47
  48-w|--web::
  49        Display manual page for the command in the 'web' (HTML)
  50        format. A web browser will be used for that purpose.
  51+
  52The web browser can be specified using the configuration variable
  53'help.browser', or 'web.browser' if the former is not set. If none of
  54these config variables is set, the 'git-web--browse' helper script
  55(called by 'git-help') will pick a suitable default. See
  56linkgit:git-web--browse[1] for more information about this.
  57
  58CONFIGURATION VARIABLES
  59-----------------------
  60
  61help.format
  62~~~~~~~~~~~
  63
  64If no command line option is passed, the 'help.format' configuration
  65variable will be checked. The following values are supported for this
  66variable; they make 'git-help' behave as their corresponding command
  67line option:
  68
  69* "man" corresponds to '-m|--man',
  70* "info" corresponds to '-i|--info',
  71* "web" or "html" correspond to '-w|--web'.
  72
  73help.browser, web.browser and browser.<tool>.path
  74~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  75
  76The 'help.browser', 'web.browser' and 'browser.<tool>.path' will also
  77be checked if the 'web' format is chosen (either by command line
  78option or configuration variable). See '-w|--web' in the OPTIONS
  79section above and linkgit:git-web--browse[1].
  80
  81man.viewer
  82~~~~~~~~~~
  83
  84The 'man.viewer' config variable will be checked if the 'man' format
  85is chosen. Only the following values are currently supported:
  86
  87* "man": use the 'man' program as usual,
  88* "woman": use 'emacsclient' to launch the "woman" mode in emacs
  89(this only works starting with emacsclient versions 22),
  90* "konqueror": use a man KIO slave in konqueror.
  91
  92Multiple values may be given to this configuration variable. Their
  93corresponding programs will be tried in the order listed in the
  94configuration file.
  95
  96For example, this configuration:
  97
  98        [man]
  99                viewer = konqueror
 100                viewer = woman
 101
 102will try to use konqueror first. But this may fail (for example if
 103DISPLAY is not set) and in that case emacs' woman mode will be tried.
 104
 105If everythings fails the 'man' program will be tried anyway.
 106
 107Note about git config --global
 108~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 109
 110Note that all these configuration variables should probably be set
 111using the '--global' flag, for example like this:
 112
 113------------------------------------------------
 114$ git config --global help.format web
 115$ git config --global web.browser firefox
 116------------------------------------------------
 117
 118as they are probably more user specific than repository specific.
 119See linkgit:git-config[1] for more information about this.
