Unix and Linux

In this updated edition, authors Deborah and Eric Ray use crystal-clear instructions and friendly prose to introduce students to all of today's Unix essentials. They’ll find the information they need to get started with the operating system and learn the most common Unix commands and concepts. After mastering the basics of Unix, they’ll move on to how to use directories and files, work with a shell, and create and edit files. They’ll then learn how to manipulate files, configure a Unix environment, and run—and even write—scripts. Throughout the book—from logging in to being root—the authors offer essential coverage of Unix.
