    1. By the time the last edition of O’Reilly’s Classic Shell Scripting was published in 2005, the approach it used was already somewhat out of date and the readership it addressed on the way out. The authors assumed that one is using any one of a number of old commercial versions of Unix, and might just be sharing a system with a number of other users, when nowadays most people doing anything with a Unix-style shell are probably running Linux on their own PCs.However, don’t let that scare you [...]

    2. Solid reference text with good coverage - basics of awk, sed, regex, and quick notes on most of the commonly used Unix commands. Also a few recipes and pipelines to mine for examples. Keep it on my desk.

    3. For the most part the book is a remarkably easy read. Mainly for newbies but gives appropriate level of depth as well and certainly can serve as a good reference. All in all I think it's a successful embodiment of the "do one thing and do it well" principle the thing here being teaching the reader to use the Unix shell to their maximum advantage. It's a great book if portability of shell scripts is your concern. Authors make clear distinction between the standard POSIX features, bash/ksh languag [...]

    4. Excellent read. I find myself reaching for it daily as a reference material. It has been quite useful with my day job. The author not only explains how various commands can fit neatly together to form powerful scripts, but also explains the history of various commands and even goes more in depth into how the POSIX standard came to be in its implementation into how specific commands behave.This added insight helps in understanding not only how things work, but why they work the way they do. It al [...]

    5. The best book I've read about Shell Script. This book contains topics from baby steps to advanced scripts used in production servers.All topics are detailed with easy examples to be replicated in your own computer. For these characteristics, I strong recommend this book for who is working with operations and DevOps.

    6. Great book for learning the basics of shell programming. Great companion to The Unix Programming Environment.

    7. This book is a great introduction to the Linux (or Unix) way of combining tools, each with a specific purpose, to carry out a variety of tasks. There are many examples that will help a beginner get up to speed. This is not, however, a book for learning how to use Linux in general.
