While they're not all well-advertised, there are actually a variety of means of getting help under Unix. Man pages correspond to online manuals for programs, file formats, functions, system calls, and so forth. If you've never read one before, the best way to start is by typing 'man man ' at the command line. Of course, while man pages are a vast improvement over the online documentation of most other OSes, they suffer from many failings: some people don't like to read text on the screen not very helpful unless you already know what to look for not always accessible even when present not always present, especially under Linux frequently hard to read, as they try to be authoritative and are therefore often too technical for new users frequently out of date That said, they're still better and more comprehensive than the alternatives.

A man page short for manual page is a form of software documentation usually found on a Unix or Unix-like operating system. Topics covered include computer programs including library and system calls , formal standards and conventions, and even abstract concepts. A user may invoke a man page by issuing the man command. By default, man typically uses a terminal pager program such as more or less to display its output. Because man pages are distributed together with the software they document, they are a more favourable means of documenting software compared to out-of-band documentation like web pages , as there is a higher likelihood for a match between the actual features of the software to the documented ones.
