Designed as one of the first true\n textbooks on how to use the UNIX operating system and suitable for a wide\n variety of UNIX-based courses, UNIX and Shell Programming goes beyond\n providing a reference of commands to offer a guide to basic commands and shell\n programming. Forouzan/Gilberg begin by introducing students to basic commands\n and tools of the powerful UNIX operating system. The authors then present\n simple scriptwriting concepts, and cover all material required for\n understanding shells (e.g., Regular Expressions, grep, sed, and awk) before\n introducing material on the Korn, C, and Bourne shells. Throughout, in-text\n learning aids encourage active learning and rich visuals support concept\n presentation. For example, sessions use color so students can easily\n distinguish user input from computer output. In addition, illustrative\n figures help student visualize what the command is doing. Each chapter\n concludes with problems, including lab sessions where students work on the\n computer and complete sessions step-by-step. This approach has proven to be\n successful when teaching this material in the classroom. \n
