Full title :Expert shell scripting / Ron Peters.

Summary

"Expert Shell Scripting is a cornucopia of useful scripts and techniques collected during my years as a system administrator. Although these scripts were written from the perspective of a system administrator, you can reuse them for almost any purpose you can think of. All the code in this book demonstrates either something very useful or something unique (and possibly quite out of the ordinary). Many techniques represent solutions that would be difficult to come up with on your own." "My goal with this book is to provide greater depth than a beginning shell-scripting book by explaining not just what the code does, but in most cases how and why the specific logic was chosen. These scripts will greatly add to your scripting repertoire and increase your skill in tackling problems and choosing solutions. Most of the scripts in this book have evolved and been hardened over years in a production environment where reliability is key. This book will be an excellent resource for anyone who wants a collection of examples at their fingertips."--Jacket
