George: dbl-clicking on it fires up Terminal and opens a window. I don't think it can not do that, at least the way I've written it. That's with the executable bit set.

dsandler: thanks, I'll check those other options out. What I really liked about this script is that I can edit it in pico from the terminal, and not need any other applications. Its about as simple as it gets.

How about being able to quit Terminal from the script? That'd do the trick.
