What is the exam for? The exam proctor(s) haven't given you any recommended books or web sites to get information from? Well, anyway, if you type "UNIX shell scripting tutorials" into Google, you should get tons of hits, some with worthwhile information, others with worthless information. All of the shell scripting I have done (using Korn Shell, Bash Shell and a few others) was done with information I received either from my own references or from web sites. I don't have immediate access to the web sites at the moment, but I'll try to remember to post them here tomorrow. Good luck on your exam, by the way.
