This has proven to be an excellent reference. It provides lots of examples of common shell constructs and presents them in a format which should run well on bourne, korn, POSIX, and compatible interpreters.

For example, I was unclear on the proper syntax for a simple "if" statement with a string comparison until I read this book. Syntax is presented up-front in the first chapter so there are no lingering doubts later on.

It answered a lot of questions I still had after I finished "Learning the Korn Shell" from O'Reilley.

As opposed to other books with "practical" in the title, this one lives up to its name. I found Chapters 4 (Using Files), 5 (The Environment), and 7 (Using Filters) very helpful. The book is full of many examples of practical things, such as how to delete all blank lines in a file. This makes is valuable for the beginner, and the later chapters contain information for the more advanced shell programmer.

I got this book at a time when the guy who wrote all our shell scripts quit without notice. This book was a lifesaver, as I had to write short (and not so short) shell scripts to automate certain tasks & understand the work he did.

I would like to see more discussion in Chapter 7 (Using Filters) about combining the use of sed and the Unix/Linux command tr. I find that I have to use these together sometimes as one does things the other can't handle. This is the only suggestion I have to improve an already useful book.

Lots of examples and well explained. This book is well presented and life saver for beginners scripter. Good job Bruce Blinn.

A great book for learning shell scripting. It starts out with general syntax but then the rest of the book in filled with micro examples of things you need to write scripts, like input, output, prompting, changing case, manipulating strings, parsing and extracting data, finding file sizes, checking free space, setting screen echo on/off, read with a timeout, text substitution, doing math, here files, etc. There are also sections on portability, debugging, and common problems. I am very happy with this book and use it often when I am scripting.

I bought this book more than 2 years ago and I have not been able to find another better book to displace it, except to supplement it. Korn is good, and so is Bash; but my boss is more impressed with speed of delivery on different systems ... from portability.

This is the one shell programming book that every engineer will want to have on their desktop. It is concise without being cryptic; Blinn's prose style is clear and straightforward. The concepts and syntax of the Bourne shell are explained in great detail, without reading like a man page. The examples are excellent and are explained line-by-line. If you have been frustrated in the past by 800-page behemoths filled with whitespace, pointless diagrams, and small talk, you will be pleasantly surprised. It is simply the finest book available on the subject.

This was exactly what I needed to get up and running with understanding and writing UNIX shell scripts. The examples are very, very helpful and ties everything together (as opposed to looking at just a few small pieces of code here and there). A great reference, wish there was a similar book for PERL!!

This is the most complete and concise book for Bourne shell programming that I have ever seen. The pages are filled with examples and descriptions of how each line of code works. The examples also explain how to port these scripts to most flavors of UNIX. I currently have three copies of this book. One for work, one for home, and a backup

This book is full of tips, tricks and gottchas that take
most people years to learn the hard way. Plenty of examples
of right and wrong ways to do things. Very concise and
well written.

before I buy this book, I need to see the table of contents, could you please provide me the table of contents, Thanks
