Short for manual page, a page of on-line documentation in UNIX systems. Every UNIX command, utility, and library function has an associated man page that you can view by entering the command:
> man
For example, to find out about the man command itself, you would enter:
> man man
If you don’t know the name of the command, but only the general topic, you can use the apropos command,
> apropos
which lists all the man pages related to the specified topic.
Man pages are stored as nroff files.
