Know how to get help with specific topics. (1) At the terminal, via man <command> or apropos <command> and (2) online by googling. These are useful when you have a specific task you want to get done, not so much otherwise. Therefore, (3) Try to do things at the command line that you would normally do via mouse. If you have no idea how, google or 'apropos'. If you learn of a tool and have no idea how to use it, google more or 'man'. (3a) Do the simple stuff via the CLI--removing and moving files, examining directory contents, et cetera. (Be careful with rm! It will not warn you by default.) (3b) More complex stuff too--try editing text with a terminal editor. Many people swear by emacs and vim. They have learning curves of their own but they are worth it. Pick one. (4) Pipes and input redirection. Send the output of one command as the input to another, send the output to a file, etc. This is where your standard Unix shell gets really powerful.
