One of the nicest things about Linux is that virtually ALL commands
have on-line documentation. If you need to find out about a command,
or even the shell (bash), just enter "man <command>".
On this page, I am providing links to the man pages for some of the
commands most commonly used on IRLP systems. Just click on the link,
and the man page for the FC3 version of the command will be displayed.
