Some software developers prefer info to man for instance, GNU developers , so if you find a very widely used command or app that doesn't have a man page, it's worth checking for an info page. Virtually all commands understand the -h or --help option which will produce a short usage description of the command and it's options, then exit back to the command prompt. Try "man -h" or "man --help" to see this in action. Caveat: It's possible but rare that a program doesn't understand the -h option to mean help.
For this reason, check for a man or info page first, and try the long option --help before -h.
