man

We close this brief list with a command that provides detailed information about any Unix command. The command accesses online Unix documentation called ``manual pages'' or ``man pages'' for short. To learn more about the mv command, type

    man mv
Unfortunately the online documentation is not written with novices in mind. So if you are a beginner, it will probably take you a while to learn how to find what you want from the man pages. Then you will find this a very useful command.

The info command accesses mainly documentation for GNU software. It requires only a little effort to learn to navigate and has a self-tutorial.
