Also, when writing your perl scripts, you should use "#!/usr/bin/perl -w" instead of "#!/usr/bin/perl"... this will give you more warnings when you run your script, making errors easier to find. "use strict;" is also a nice thing to do, but you can read up on that one later.

Definitely get familiar with Unix-maybe buy a book. You'll see that alot of perl's syntax and functions are similiar to what you'll find in the Unix shells.
