Shell scripting skills never go out of style. It's the shell that unlocks the real potential of Unix. Shell scripting is essential for Unix users and system administrators-a way to quickly harness and customize the full power of any Unix system. With shell scripts, you can combine the fundamental Unix text and file processing commands to crunch data and automate repetitive tasks. But beneath this simple promise lies a treacherous ocean of variations in Unix commands and standards. "Classic Shell Scripting" is written to help you reliably navigate these tricky waters. Writing shell scripts requires more than just a knowledge of the shell language, it also requires familiarity with the individual Unix programs: why each one is there, how to use them by themselves, and in combination with the other programs. The authors are intimately familiar with the tips and tricks that can be used to create excellent scripts, as well as the traps that can make your best effort a bad shell script. With "Classic Shell Scripting" you'll avoid hours of wasted effort. You'll learn not only write useful shell scripts, but how to do it properly and portably.The ability to program and customize the shell quickly, reliably, and portably to get the best out of any individual system is an important skill for anyone operating and maintaining Unix or Linux systems. "Classic Shell Scripting" gives you everything you need to master these essential skills.

This book is well written and full of information. The authors are following a more practical approach with a lot of usefull real-life examples. However, they understand to provide a lot of background information that explains the idea behind unix tools and thus demonstrate how to use unix in a powerfull way. therefore this bok is more than just a shell introduction, it is in principle a unix introduction, because unix is based upon shells. And whenever possible some remarks about the history and development of unix is given.
This book is a far more practical introduction compared to some others (e.g 'Learning the bash shell'), but it also explains much more about the unix environment. For me there is no problem not to focus on a specific shell, since the use of unix tools is similar for several shells. If you use also 'Linux in a nut shell' you might have enough information for each kind of shell plus some more description of the various unix tools.
I really can recommend this book to anyone who wants to understand the unix shell and learn how to write good shell scripts.
Es erfüllt letztendlich genau seinen Zweck, ist aber nicht vollständig "was man von einem Buch mit diesem Titel und vor allem dieser Seiten Zahl nicht erwarten kann"
Man sollte vielleicht darüber nachdenke sich noch das grep sowie das "sed & awk" Buch dazu zu kaufen.

I'm now writing a lot of little (and not so little; 1200 lines of bash scripts so far) shell scripts. There were always several little nuances that always bugged me, but the examples helped me remember how to do what.
And there are a lot of examples of not only bash (and sh, ksh) but sed, awk, and others that help you along.
Worth keeping on your bookshelf. I'd buy it again in a second.
Korn Shell is the popular one and now I find myself even more comfortable and confident in writing shell scripts with heavy error trapping and being elegant in exiting properly. Excellent book and now I'm on to reading the O'Reilly book "Learing the Korn Shell" by Bill Rosenblatt
I'd definitely recommend it to anyone new to Linux or even experienced Linux users looking to get a better understanding of the Shell.
