| 520 | 8 | |a Annotation GNU/Linux is a remarkable operating system that comes with a complete development environment that is stable, reliable, and extremely powerful. The shell being the native interface to communicate with the operating system is capable of controlling the entire operating system. There are numerous commands on Linux shell which are documented but hard to understand. The man pages are helpful but they are very lengthy and it does not give any clues on key areas where commands can be used. Proper usage of shell commands can easily solve many complex tasks with a few lines of code, but most linux users don't have the right know-how to use the Linux shell to its full potential. Linux Shell Scripting Cookbook is a collection of essential command-line recipes along with detailed descriptions tuned with practical applications. It covers most of the commands on Linux with a variety of usecases accompanied by plenty of examples. This book helps you to perform complex data manipulations involving tasks such as text processing, file management, backups and more with the combination of few commands. Linux Shell Scripting Cookbook shows you how to capitalize on all the aspects of Linux using the shell scripting language. This book teaches you how to use commands to perform simple tasks all the way to scripting complex tasks such as managing large amounts of data on a network. It guides you on implementing some of the most common commands in Linux with recipes that handle any of the operations or properties related with files like searching and mining inside a file with grep. It also shows you how utilities such as sed, awk, grep, cut can be combined to solve text processing related problems. The focus is on saving time by automating many activities that we perform interactively through as browser with a few lines of script. This book will take you from a clear problem description to a fully functional program. The recipes contained within the chapter will introduce the reader to specific problems and provide hands-on solutions.
