When learning a programming language, I often create little example files to demonstrate different ways I've learned to do things. I am in the process of putting them up on the website that's attached to this blog (via the Navigator panel).
The first example is in Perl and describes general things like printing, variables, comments, basic string handling, if/then/else constructs, loops, and basic Perl hashes.

Be sure to read the DISCLAIMER too.
I have a bunch more I'll be posting over the next while.
