Accessing Git’s Online Help
You can ask the git command for help using the git help command. By default, it just gives a list of the most common commands:
$ git help
The most commonly used git commands are:
add Add file contents to the index
apply Apply a patch on a git index file and a working tree
archive Create an archive of files from a named tree
...
You can also get a complete list of all the commands:
$ git help -a
git commands available in '/usr/bin'
------------------------------------------
add gui reflog
add--interactive hash-object relink
am http-fetch remote
...
Finally, you can get the Unix manpage for a particular command (every Git command, even the obscure ones, has a manpage). For example, to get help for the git add command:
$ git help add
