Introduction

Welcome to the fourth edition of Sams Teach Yourself Unix in 24 Hours! This book has been designed to be helpful as a guide as well as a tutorial for both beginning users and those with previous Unix experience. The reader of this book is assumed to be intelligent, but no familiarity with Unix is expected or required.

Does Each Chapter Take an Hour?

You can learn the concepts in each of the 24 lessons in one hour. If you want to experiment with what you learn in each lesson, you might take longer than an hour. However, all the concepts presented here are straightforward. If you are familiar with Windows applications or the Macintosh, you will be able to progress more quickly through the lessons.
