It's a book on shell scripting

More than you ever wanted to learn about the bash shell. Good reference for sysadmins.

Outstanding in every way

I first bought this book over 12 years ago, and I still use it as the standard by which other books are measured. It must be one of my top 5 favorite computer books, ever.

The author clearly understands the material, and makes it approachable, direct, and easy to learn without being too light or condescending. I wish the same could be said of Java books.

"Learning the bash Shell" is the right size and right price, too. Perfect in every way.

O'Reilly kind of took a turn for the worse in the late '90s / early 2000s, but this was originally published back when they were good the first time. (They've since recovered, IMO)

If you have need to learn the bash shell, you can't go wrong with this one.

Very useful

This book provided a solid resource to start writing shell scripts in bash. It is well written, and also provides understanding into some bash features that go beyond just a reference book.

Great book

I have owned this book for awhile, and over the years it has been my only reference to the bash shell I have felt a need for.

The only down points I have seen in this book is that some of the info seems to be seperated out a bit, making some info hard to find at times (although if you have a hard time using an index, well, bash may be a bit advanced for you), but everything is covered well, and the appendixes are fairly good.

The first thing users of the Linux operating system come face to face with is the shell. "Shell" is the UNIX term for a user interface to the system -- something that lets you communicate with the computer via the keyboard and display. Bash, the Free Software Foundation's "Bourne Again Shell," is the default shell for Linux, the popular free UNIX-like operating system. It's also a replacement for the standard UNIX Bourne shell, which serves both as a user interface and as a programming language. Like the FSF's other tools, bash is more than a mere replacement: it extends the Bourne shell in many ways. Features include command line editing, key bindings, integrated programming features, command completion, control structures (especially the select construct, which enables you to create menus easily), and new ways to customize your environment.

Whether you want to use bash for its user interface or its programming features you will find Learning the bash Shell a valuable guide. The book covers all of bash's features, both for interactive use and programming. If you are new to shell programming, Learning the bash Shell provides an excellent introduction, covering everything from the most basic to the most advanced features, like signal handling and command line processing. If you've been writing shell scripts for years, it offers a great way to find out what the new shell offers. The book is full of examples of shell commands and programs that are designed to be useful in your everyday life as a user, not just to illustrate the feature being explained. All of these examples are freely available to you online on the Internet.

This second edition covers all of the features of bash Version 2.0, while still applying to bash Version 1.x. New features include the addition of one-dimensional arrays, parameter expansion, and more pattern-matching operations. bash 2.0 provides even more conformity with POSIX.2 standards, and in POSIX.2 mode is completely POSIX.2 conformant. This second edition covers several new commands, security improvements, additions to ReadLine, improved configuration and installation, and an additional programming aid, the bash shell debugger.

With this book you'll learn:

How to install bash as your login shellThe basics of interactive shell use, including UNIX file and directory structures, standard I/O, and background jobsCommand line editing, history substitution, and key bindingsHow to customize your shell environment without programmingThe nuts and bolts of basic shell programming, flow control structures, command-line options and typed variablesProcess handling, from job control to processes, coroutines and subshellsDebugging techniques, such as trace and verbose modesTechniques for implementing system-wide shell customization and features related to system security
