This new book by best-selling author Mark Sobell combines the strengths of a tutorial with those of a reference to give you the knowledge and skills to master Red Hat Linux. Uniquely designed for both beginners and experienced users, A Practical Guide to Red Hat Linux requires no prior programming experience. It begins with an extensive tutorial to bring those with less experience up to speed, and then quickly progresses to detailed chapters on GUIs, networking, popular shells, programming tools, Red Hat Linux filesystems, and system administration. Part two is a comprehensive reference containing descriptions and examples of many utilities. The book takes a truly practical approach to the study of Red Hat Linux by the use of tutorial examples that show you what you will see on the screen each step of the way.
Mark G. Sobell is president of Sobell Associates Inc., a consulting firm that specializes in UNIX/Linux training, support, and custom software development. He is the author of many best-selling UNIX and Linux books and has more than twenty-five years of experience working with UNIX and Linux.
(Each chapter concludes with a Chapter Summary and Review Exercises.)
