Guide to Unix/Linux Commands

In October 2005 I contributed to the Guide to Unix/Linux commands wikibook. It is targeted at users who want to learn the shell commands by typing them on a Unix or gnu/Linux console. The wikibook is nowhere near complete but I guess it would be a good start if want to master the shell. For experienced users I request you to spare some time and contribute to this wikibook. If possible please try to adopt this documentation project.

The Guide to Unix/Linux Commands

The Guide to Unix/Linux command line is often considered difficult to learn. This book aims to help beginners by introducing various commands in lucid and simple language. Unlike most command references, this book is designed to be a self-study guide.
