Summary: Best Unix Shell for everyone - Beginners and Advanced users
Review: Unix Shells by Example is my sixth UNIX-based programming book. And certainly the BEST of all. DOS-like Command-line oriented interface has been my favorite over windows for obvious reasons... I have been working with them since the days of Wordperfect5 (wp5) for DOS; ... way before the introduction of Windows 3.1. Since then, I have gone through several batch scripting/programming books. Now transitioning to the world of Linux/Unix, I was disappointed by all the shell programming books that I have used so far before coming across Ellie Quigley's book. It was so good that 3 of my colleagues ordered a copy each (a new 3rd edition).Pros: Provides a step-by-step on how-to accomplish a real-world task with a sample code. Plus a concise & straight forward narrative/explanation of every line or special character used in the examples. Before reading this book, I have used many Unix symbols without knowing the reasons behind their use or alternate options. Other books have always provided a generalized answer of "it is the standard procedure". Such as "#!/bin/ksh"
Also, it provides comparison between various flavors/versions of unix shells. So where ever you find your self in, whether you inherited a system with scripts written in Csh, Sh, bash, or my favorite 'ksh'; there is an answer for it in the book. Cons: the author could have provide more than one scenario for each of the examples.
