Book Description
Unix Shell Programming is a tutorial aimed at helping Unix and Linux users get optimal performance out of their operating out of their operating system. It shows them how to take control of their systems and work efficiently by harnessing the power of the shell to solve common problems. The reader learns everything he or she requirements to know to customize the way a Unix system responds.
The vast majority of Unix users utilize the Korn shell or some variant of the Bourne shell, such as bash. Three are covered in the third edition of
Unix Shell Programming. It begins with a generalized tutorial of Unix and tools and then moves into detailed coverage of shell programming.
Topics covered include: regular expressions, the kernel and the utilities, command files, parameters, manipulating text filters, understanding and debugging shell scripts, creating and utilizing variables, tools, processes, and customizing the shell.

Reader Reviews
"UNIX Shell Programming, 3rd Ed" (USP3E) is probably the book to buy if you're a beginning UNIX user with dreams of writing shell scripts. The book does a good job of explaining many of the key concepts needed to get real work done on UNIX systems. While readers with advanced backgrounds will prefer a book like "Mastering UNIX Shell Scripting" by Randal Michael, USP3E will please most UNIX scripting newbies. USP3E begins with a review of the basics -- working with files and directories, redirecting input/output, pipes, and the shell itself. Chapter four's discussion of regular expressions is generally useful, although "saving matched characters" on p. 64 was confusing. This made the "command substitution" material on p. 129 unclear. Chapter six was devoted to the use of different sorts of quotes, which seems excessive until one realizes the significant differences between using single and double quotation marks in scripts. Attention to detail like this, along with generous inclusion of sample scripts, helped this book earn a strong rating. While the book includes examples of using sed, awk is not mentioned. Sed could have received more coverage as well. While the authors direct interested readers to other books, perhaps a future edition might include chapters devoted to sed and awk? While the publisher's site doesn't mention a source for errata, it is available by contacting the authors. Overall, I liked this book. It is up-to-date and compares favorably to the other books I consider reading to learn more about UNIX shell scripting. Armed with the knowledge gained from USP3E, readers should be equipped to automate some routine tasks. They will also be able to progress to more advanced shell scripting resources.
