GETTING HELP IN UNIX
====================

The general help command in Unix is 'man' - it displays pages of
the Unix manual directly on your screen.  So to find out more
about the 'ls' command you would type

	man ls

The 'man' command can also do a keyword search for all the manual
pages dealing with a certain topic.  To do a keyword search add
the '-k' flag to the command, followed by the keyword.  For
example,

	man -k mail

would list all the manual pages that have the word "mail" in
their titles.  The result might be a list looking something like
this:

aliases (5)    - aliases file for sendmail
biff (1)       - be notified if mail arrives and who it is from
binmail (1)    - send or receive mail among users
from (1)       - who is my mail from?
mail (1)       - send and receive mail
msgs (1)       - system messages and junk mail program
newaliases (1) - rebuild the data base for the mail aliases file
sendmail (8)   - send mail over the internet

You could then find out more about the msgs program by saying

	man msgs

To list all of the available Unix commands use

	man intro

You can get a printed copy of the manual pages by "piping"
the output of the man command to the lpr command, like so

	man intro | lpr
