This book is geared towards any Unix user who doesn't want to spend time creating or testing shell scripts. Instead, Shell Scripting Recipes dissects and explains over 150 much-needed and practical real-world examples, and then shows the reader how and when to appropriately use them. Because most scripts found in this book are POSIX (Portable Operating System Interface)-compliant, they are supported by many of the major shell variants, including Bash, ksh and sh, among others. File conversion, system administration, and resource monitoring are just a few of the topics covered in this highly practical shell scripting reference.

The bash shell is a complete programming language, not merely a glue to combine external Linux commands. By taking full advantage of shell internals, shell programs can perform as snappily as utilities written in C or other compiled languages. And you will see how, without assuming Unix lore, you can write professional bash 4.0 programs through standard programming techniques. Complete bash coverage Teaches bash as a programming language Helps you master bash 4.0 features.

When I was introduced to Unix in 1990, it was still the domain of multiuser systems and high-end workstations. Even the i386 system I started with had 12 users logging on concurrently through serial terminals. I had remote access through a blazingly fast 1200 bps modem. Things were changing by the mid-1990s, when systems using the Linux kernel, integrated with GNU utilities and the X Window System, provided a viable alternative to Microsoft Windows. At the same time, computers with the power, memory, and hard drive space to run it came within reach of an individual's pocketbook. The Internet brought fast and efficient distribution of the new systems and software (and enabled their development in the first place). Unix had arrived on the home computer. The twenty-first century has seen the burgeoning of a new breed of Unix user: the home (or small business) user whose computer experience was previously limited, at most, to Microsoft Windows. Such computers may well be used by only one person. This modern user quite likely has no intention of becoming a system administrator, and just wants to use the computer with as little fuss as possible.
