In Detail

Zsh has become incredibly popular in recent times and reasonably so; the shell boasts some really great features such as command completion, filename generation, and history sharing among instances of the shell. Learning to use them to your advantage will prove to be really valuable and will save you from lots of tedious and overly-complex tasks.

This hands-on guide will show you how to configure and use Zsh for work and daily tasks. It provides a clear introduction to the more powerful features of the shell such as globbing and completion. This book will help you take advantage of the real power behind the UNIX shell on both desktops and servers through real-world examples.

This book will help you understand the features of Zsh and make it one of the most valuable assets in your toolbox. It will teach you how to use the shell history to look up and edit previously typed entries and take advantage of the line-editor module to speed up your typing and editing of commands. You will be able to create your own completion functions and ensure you never mistype a command or have to look at the manpages again.

You will learn how to define your own aliases and learn about filename generation so you can do more by typing even less. You will also discover the essentials of Zsh and go deeper with its more advanced features. When you are done with this book, your time with the command line will be much more enjoyable and productive.
