Linux Command Summary
For more information on the following commands, type man and the name of the command to see a help manual for that command. You can open another terminal window at the same time to type the man command and see the helpful text. Some commands, like alias, are built into bash. For these, type man bash to get help. If you type man <command> and the response is No manual entry for <command>, it is likely built into bash. Online help is also available for shell built-in commands and other core commands.
