How can I use Perl's built in help?

An easy way to get perl help on your system is to type:
perldoc
at a shell prompt. It will print the following help message, and if you want help on a particular funcion, do:
perldoc -f funcname
and get the help. Read the help message for more options!

Here are some helpful commands for getting help with Perl. You can also run
perldoc
to get additional help (You can't run it as root on *nix)

http://www.perl.com also has extended help on the site.
