Linux+ 2005 in depth

Complete with extensive chapter summaries and end-of-chapter review questions, "Linux+ 2005 In Depth" serves as a practical guide that maps completely to CompTIA's 2005 Linux+ certification objectives and is designed to prepare readers to successfully pass the exam. The topics introduced in this book-and covered in the certification exam-are geared toward systems administration; however, they are also well suited for those who plan to use or develop programs for Linux systems.
