Great book!! Start here, then read Stevens.
Robbins are a better place to start for UNIX programming than the Stevens' books. This book and "Practical UNIX Programming" by Kay A. Once you complete this book, you can move on to Stevens.

This book deserves your attention if you are learning UNIX
The author definitely knows how to teach UNIX programming. I have the 9th edition of this book. If you are busy at work for Java, ActiveX, C++ like me, you will appreciate its concise while accurate content to get you started.
