Pressestimmen
"Classic Shell Scripting ist ohne Zweifel sehr gut geschrieben. Der lebendige Stil bindet das Interesse, die Beispiele sind nicht zu komplex und somit wirklich gut nachvollziehbar. Sie lenken den Blick auf die zu vermittelnden Techniken, so kann sich der Leser wirklich immer auf seinen aktuellen Fokus konzentrieren. Jedes Kapitel schließt mit einer 'Summary', die die besprochenen Themen rekapituliert. [...] Es [das Buch] ist auf jeden Fall eine große Bereicherung für das Regal jedes Shellprogrammierers." -- Ronald Schaten, Hitforum.de, 07/2005 Lesen Sie die ausführliche Rezension unter: http://hitforum.de/0-596-00595-4.php
Kurzbeschreibung
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.

Format:Taschenbuch
This book promises to introduce into the unix shells without focusing on a specific one like bash csh and so on. Instead xis tried to keep according to the POSIX standards, which allows writing scripts that are really portable between platforms. Whenever there are traps with some functions they are shown and explained. Important unix tools are explained with a brief listing of the function call and its options. This book also covers sed and awk to the some extend it is required for using.
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.

Book Review: Classic Shell Scripting

Classic Shell Scripting
Hidden Commands that Unlock the Power of Unix
By Arnold Robbins, Nelson H.F. Beebe
First Edition May 2005
ISBN: 0-596-00595-4
558 pages, $34.95
[...]
I found this to be quite a useful book for learning more about Unix/Linux shell scripting. I would consider this one to be an intermediate level text, and complete beginners might be better served by a more simplified book. There are quite a bit of in-depth details included, and many very nice examples and code snippets. Like all O'Reilly books, it is well organized and formatted, and clearly written.
The book opens with a brief history of Unix and how important the shell (and scripting) is to it. There are some comparisons with other programming languages, and why it is sometimes preferable to use a script versus a compiled program. The very basics of how scripts are written and used are also mentioned here, and beginners may want to refer to an additional book for more of the basic instructions.
The next few chapters cover mostly text processing with scripts, including searching, sorting, printing, extracting, and counting methods. Good examples are used, including the use of regular expressions and pipes to increase the power of your scripts. Following this, there are several chapters on more advanced scripting, including how to use variables, loops, functions, standard I/O, redirection, wildcards, using "awk", and working with external files. Extensive example code is provided throughout.
The remaining chapters of the book get into more advanced subjects such as database manipulation, process control, and increasing the security of scripts. Portability and shells other than bash are also discussed.
Perhaps the most interesting part of the book (for me) were the Appendices and other sections at the end. Appendix A is entitled "Writing Manual Pages", and is extremely informative on how to produce and format a valid man page. This is a much more complicated process than I had previously known (can you say "groff"?), and is quite interesting. For anyone who has ever complained about a poor man page, this will give you all the tools you need to write an improved version! :) Appendix B has some excellent in-depth discussion about Unix files and filesystems, including attributes and permissions. Appendix C is a summary of important Unix commands for shell scripting, categorized by function, which is a good quick reference list. Following this, there is an excellent Bibliography that recommends related books for further reading. Finally, there is good Glossary and an Index.
Overall, I found the book to be excellent in it's content and quality. I would recommend that a beginner also find a companion book to more gently introduce the fundamentals of shells and scripting, but this volume is excellent for the intermediate to advanced user. If you want to fully use the power of the Unix/Linux shell, this is a "must-have" book! Well done to the authors and O'Reilly Publishing.

Practical and useful
19. September 2005
Format:Taschenbuch
Great book. The emphasis is nicely split between actually using the shell itself and the whole supporting cast of unix tools (sed, awk, cut, join, sort etc.) The idea of carefully crafting solutions using the unix toolbox mindset is key. I also like the fact he doesn't try to teach to multiple shells, but first tries to emphasize portability by sticking mainly to a POSIX standard, and only later adds info about non standard shell topics. If I could only have one book on shell scripting, this would be it. The best description is 'Practical'.

This might be a great second book on shell scripting.
5. Juni 2005
Format:Taschenbuch
This might be a great second book on shell scripting. Can serve as a valuable add on to "Learning Korn shell" from O'Reilly -- also a very strong book on shell scripting.
The authors provide a lot of interesting and useful information that is difficult to find in other books. They devoted Ch 5 to piping and in 5.4 "Word List" they discuss famous Doug McIlroy alternative solution to Donald Knuth program of creating the list of the n most-frequent words, with counts of their frequency of occurrence, sorted by descending count from an arbitrary text file.
The authors discuss many Unix tools that are used with shell (Unix toolbox). They provide a very good (but too brief) discussion of grep and find. Discussion of xargs (which is usually a sign on a good book on scripting) includes /dev/null trick, but unfortunately they do not mention an option -0n with which this trick makes the most sense.
One of the best chapters of the book is Ch. 13 devoted to process control. Also good is Chapter 11 that provides a solution to pretty complex and practically important for many system administrators task of merging passwd files in Unix. It provides a perfect insight into solving real sysadmins problems using AWK and shell.
Shortcomings are few. in "5.2. Structured Data for the Web" the authors should probably use AWK instead of SED. Also XML processing generally requires using a lexical analyzer, not regular expressions. Therefore a tag list example would be better converted to something simpler, for example generating C-tags for vi.
