6 git-help - display help information about git
11 'git help' [-a|--all|-i|--info|-m|--man|-w|--web] [COMMAND]
16 With no options and no COMMAND given, the synopsis of the 'git'
17 command and a list of the most commonly used git commands are printed
18 on the standard output.
20 If the option '--all' or '-a' is given, then all available commands are
21 printed on the standard output.
23 If a git command is named, a manual page for that command is brought
24 up. The 'man' program is used by default for this purpose, but this
25 can be overridden by other options or configuration variables.
27 Note that `git --help ...` is identical to `git help ...` because the
28 former is internally converted into the latter.
34 Prints all the available commands on the standard output. This
35 option supersedes any other option.
39 Display manual page for the command in the 'info' format. The
40 'info' program will be used for that purpose.
44 Display manual page for the command in the 'man' format. This
45 option may be used to override a value set in the
46 'help.format' configuration variable.
48 By default the 'man' program will be used to display the manual page,
49 but the 'man.viewer' configuration variable may be used to choose
50 other display programs (see below).
54 Display manual page for the command in the 'web' (HTML)
55 format. A web browser will be used for that purpose.
57 The web browser can be specified using the configuration variable
58 'help.browser', or 'web.browser' if the former is not set. If none of
59 these config variables is set, the 'git web{litdd}browse' helper script
60 (called by 'git help') will pick a suitable default. See
61 linkgit:git-web{litdd}browse[1] for more information about this.
63 CONFIGURATION VARIABLES
64 -----------------------
69 If no command line option is passed, the 'help.format' configuration
70 variable will be checked. The following values are supported for this
71 variable; they make 'git help' behave as their corresponding command
74 * "man" corresponds to '-m|--man',
75 * "info" corresponds to '-i|--info',
76 * "web" or "html" correspond to '-w|--web'.
78 help.browser, web.browser and browser.<tool>.path
79 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
81 The 'help.browser', 'web.browser' and 'browser.<tool>.path' will also
82 be checked if the 'web' format is chosen (either by command line
83 option or configuration variable). See '-w|--web' in the OPTIONS
84 section above and linkgit:git-web{litdd}browse[1].
89 The 'man.viewer' config variable will be checked if the 'man' format
90 is chosen. The following values are currently supported:
92 * "man": use the 'man' program as usual,
93 * "woman": use 'emacsclient' to launch the "woman" mode in emacs
94 (this only works starting with emacsclient versions 22),
95 * "konqueror": use 'kfmclient' to open the man page in a new konqueror
96 tab (see 'Note about konqueror' below).
98 Values for other tools can be used if there is a corresponding
99 'man.<tool>.cmd' configuration entry (see below).
101 Multiple values may be given to the 'man.viewer' configuration
102 variable. Their corresponding programs will be tried in the order
103 listed in the configuration file.
105 For example, this configuration:
107 ------------------------------------------------
111 ------------------------------------------------
113 will try to use konqueror first. But this may fail (for example if
114 DISPLAY is not set) and in that case emacs' woman mode will be tried.
116 If everything fails, or if no viewer is configured, the viewer specified
117 in the GIT_MAN_VIEWER environment variable will be tried. If that
118 fails too, the 'man' program will be tried anyway.
123 You can explicitly provide a full path to your preferred man viewer by
124 setting the configuration variable 'man.<tool>.path'. For example, you
125 can configure the absolute path to konqueror by setting
126 'man.konqueror.path'. Otherwise, 'git help' assumes the tool is
132 When the man viewer, specified by the 'man.viewer' configuration
133 variables, is not among the supported ones, then the corresponding
134 'man.<tool>.cmd' configuration variable will be looked up. If this
135 variable exists then the specified tool will be treated as a custom
136 command and a shell eval will be used to run the command with the man
137 page passed as arguments.
142 When 'konqueror' is specified in the 'man.viewer' configuration
143 variable, we launch 'kfmclient' to try to open the man page on an
144 already opened konqueror in a new tab if possible.
146 For consistency, we also try such a trick if 'man.konqueror.path' is
147 set to something like 'A_PATH_TO/konqueror'. That means we will try to
148 launch 'A_PATH_TO/kfmclient' instead.
150 If you really want to use 'konqueror', then you can use something like
153 ------------------------------------------------
158 cmd = A_PATH_TO/konqueror
159 ------------------------------------------------
161 Note about git config --global
162 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
164 Note that all these configuration variables should probably be set
165 using the '--global' flag, for example like this:
167 ------------------------------------------------
168 $ git config --global help.format web
169 $ git config --global web.browser firefox
170 ------------------------------------------------
172 as they are probably more user specific than repository specific.
