git-help(1)
NAME
git-help - Display help information about Git
SYNOPSIS
git help [-a|--all] [-g|--guide]
[-i|--info|-m|--man|-w|--web] [COMMAND|GUIDE]
DESCRIPTION
With no options and no COMMAND or GUIDE 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 --guide or -g is given, a list of the useful Git guides is also printed on the standard output. If a command, or a guide, is given, a manual page for that command or guide is brought up. The man program is used by default for this purpose, but this can be overridden by other options or configuration variables. 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. This
option overrides any given command or guide name.
-g, --guides
Prints a list of useful guides on the standard output. This option
overrides any given command or guide name.
-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.

Opportunity
Personal Opportunity - Free software gives you access to billions of dollars of software at no cost. Use this software for your business, personal use or to develop a profitable skill. Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.
Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.
Free Software
Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.
Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.
Free Books
The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.
Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.
Education
Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.
Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
