Great idea for a show and a most interesting script.

I always like looking at other people's code; it gives an insight into how they think and solve problems, and there are often good ideas to make you consider how you'd solve a similar problem. I'm always looking for new and better ways of doing stuff.

I never use 'getopt' for example. It wasn't about when I first started using Unix and 'sh', so I always use the older 'getopts'. You have made me rethink this choice - thanks!

There are one or two parts of this script I don't quite understand so I have emailed you about them. This clunky comment system is not the best place to have such a dialogue.

More like this please!
