"Linux Shell Scripting with Bash" emphasizes professional scripting solutions through the use of structured programming and standard Linux development tools. The book focuses on the Linux environment and the robust tool set therein. Because the shell relies on the operating system for its functionality this is the ideal methodology to learn shell scripting and sets the book apart from general scripting titles. Promoting good programming practices with real-world scripts, which are readable, extendable, and easy to debug, this book will be an essential asset to any Linux user.
