Ajt: Thanks a lot for your comments! As as I said in my previous post, the main purpose of the script was to test some recently acquired skills; I wasn't aiming at trying to compete with a full featured program. I was aware that there were many other tools for this job already, but I just wanted to give it a go for the fun of it.

Please forgive me if it sounded like it was a new solution to a not yet solved problem. I am the first to acknowledge that, in its current state, this little script is far from being robust and safe to use by anyone in any platform.
