Yes I have googled Bash programming, there is some in both of my Linux books also, but sometimes there is too much information. I spent an hour trying to find out then decided to ask here. I always wonder at people who ask if I have googled yet. This is, after all, a forum all about answering questions rather than avoiding them. When someone asks me a question, I answer it if I have the ability to do so, and pass it by if I don't. I am not flaming you; just trying to get you to think.
Thank you very much for your succinct answer; I will put it to use immediately.
Have a good day.
