|Man Command To Find The Man Page
The Unix commands covered in this section: man
UNIX has a built-in documentation system known as man pages. Since UNIX was originally developed as an environment for programmers, man pages tend to be fairly terse (some might say cryptic!). However, it is possible for novice users to glean an occasional bit of wisdom from them.
Use the man command to find the man page for the ls command.
% man ls
User Commands ls(1)
If the requested man page is too long to be displayed on a single screen (usually the case), it will be displayed in a pager (the default is more). To move forward through the page, use the space bar. To move backward, press the 'b' key. To quit, press 'q'.
Notice that you must know the name of a given command to see the corresponding man page. You can use the "-k" option to search for man pages related to a specified keyword.
Use man -k to search for man pages related to "telnet"
% man -k telnet
If you were interested in the telnet server (in.telnetd), you could then enter man in.telnetd at the shell prompt.
Since man pages are not really aimed at novice users, you may wish to consult a book. There are many to choose from, but most are hundreds of pages long and therefore a bit scary!
