First of all, thank you all very much for your replies and for the warm welcome, I have a feeling that I will be returning here a lot in the foreseeable future :).

Your explanations are a huge help, I have been reading the perldoc a lot the past couple of days, but seeing code in a context I have been working in just clears up so much more for me! I will study all of your answers thoroughly until I understand every last bit of code in them!

I'm sorry about the line numbering, I am using a version of VIM that has no clipboard support so I have to copy my whole command line screen, including the line numbers (still need to look for some plugin/other version of VIM, in the meantime I guess I'll just open my code in another editor to paste it here :).
