Learn the basics, followed by the more advanced skills you will need to become an Enterprise Linux administrator. This book will prepare you to use Linux effectively with a clearer understanding of what is needed to successfully leverage new opportunities.After building a solid Linux knowledge foundation, you will learn how three major community Linux distributions are installed, configured, and used. The book will then guide you through all the different configurations a Linux administrator should know, along with some useful exercises for you to practice.
