Taylor: That's a tough one, particularly since they now have with different operating environments the ability to popup dialogue windows and other graphical user interface elements from within a shell script. So I would say that for fairly lightweight tasks, there's very little you can't do with a shell script. I could, for example, do a flat file database all as shell scripts. Because when you think about it, a shell script is really just a way for you to put together all the power of the thousands of different Unix commands in a coherent fashion. Anything you can do on the command line, you can do in a shell script in an automated fashion. When you're ready to crack open the hood and soup up your engine a little bit, then there's a tremendous amount of power underneath there.
Gaskin: Well, that's wonderful. And the book again is Wicked Cool Shell Scripts, written by Dave Taylor, one of his 16 books. Thanks for your help Dave.
