UNIX Shell Commands Quick Reference

This little (152-page) book takes the mystery out of Bourne and Korn shell programming. It treats topics like logical operators, arithmetic, programming constructs (if, for, while, etc.) giving numerous, concise examples. Applications for standard commands are presented including a large vi reference section. I particularly like the explanation of the "exec" command - easy to understand yet thorough, like the entire book. I don't do enough UNIX scripts to warrant wading through a huge reference book and I suspect there are many others like myself. If you are a competent programmer in two or more languages, this book should be enough to get you on your way doing shell programming.
