“This new edition covers a lot of important ground and is well worth that special spot you've on your bookshelf for the book that you need to be able to reach without standing up. This is one of those books you are likely to make very good use of in your Unix work life.”—Computerworld“An excellent book if you want some ideas and inspiration on what's made possible by writing bash scripts. There are some really interesting techniques, and the book is fun to read.”—I Programmer“Whether users want to save time managing their systems or just find new ways to goof off, these scripts are just the ticket.”—Linux Journal“If you’re just getting to grips with Bash scripting, following these examples will give you a great insight into how it all works.”—Network Security Newsletter"My current day job has a variety of CLI tools written in Bash, Perl and Python. Previous to reading this book I wasn’t confident in modifying the old Bash scripts and would rewrite them in Perl or Python. Now I have more confidence and understanding."—Paul Baccas“If you want to get more out of using the command line (on pretty much any UNIX like OS) this could be the book for you.”—euro tech news
