[aklug] Re: Simplest way to do this in bash?

Awww, man. I can't believe you didn't say RTFM... ;)

No, in reality Bryan... thank you for not saying that.
It's been a pain always hearing that from more experienced linux users.

On the flip side of the development circle Christopher...
Try creating your software this way...

1. Requirements
2. Design
3. Program Test for Class 1
4. Program Class 1
5. Run Test
6. Move onto next Class

This way when you're done, you've got a full set of tests developed
along with your software.
