Summary

The first thing that you should have gotten from this tutorial is how to stop a regular expression from grabbing more information than you wanted it to. There are many regular expression tutorials out there but many over look this so hopefully you now have some idea of how to make a regular expression only grab the exact amount of information you want it to grab and nothing more.

The other important thing you should have gathered from this article is how to use File::Find to parse all files in a directory and its subdirectories. The File::Find module works on most operating systems so it is much better than doing a system call to ls or dir which is what most people did before Find::Find was created.
