UNIX and Shell Programming, meant for a wide range of UNIX-based courses, is one of the first real textbooks on using the UNIX operating system. It offers a tutorial on shell programming and basic commands, in addition to a command reference. Students are first introduced to the fundamental commands and tools of the potent UNIX operating system by Forouzan and Gilberg. Before introducing information on the Korn, C, and Bourne shells, the authors first cover all the material needed to understand shells, including Regular Expressions, grep, sed, and awk. After that, they introduce basic scriptwriting concepts. Throughout, rich visuals assist concept presentation and in-text learning aids promote active learning. For instance, color is used in sessions so that students can quickly discern between computer output and user input. Illustrative figures also assist students in understanding what the command is accomplishing. Problems, including lab sessions where students use a computer to work through sessions step-by-step, are included at the end of each chapter. When teaching this content in the classroom, this method has shown to be effective.
