To get a sense of all the things Perl can do, poke around Code Catacombs (for example scripts) and the Library (for information about Perl itself)-- in the Library pay special attention to perlfunc. If you have Perl installed on your computer, you can get the same information that you will find in the Library by typing 'perldoc' at a command line. If you are curious about a specific function and you think you know the name of the function, you can do 'perldoc -f function-name'.
