In todays IT environment, harried system administrators are finding themselves more overworked than ever. This book helps them regain some of the lost time spent creating and testing shell scripts, and guides readers through more than 150 much-needed and practical real-world examples.

Because all scripts found in this book are POSIX (Portable Operating System Interface)-compliant, they are supported by all major shell variants, including Bash, Zsh 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.
