This text is written especially for undergraduates and designed to provide them with a thorough grounding in the UNIX technology. The text provides complete coverage of AT&T's System V UNIX and shell programming with both Bourne Shell and the C Shell. It features an in-depth introduction to ASK (a pattern scanning and processing language) and sed (stream editor). Procedure design is emphasized throughout. Reflecting its origin as a text written expressly for undergraduates, the text has exceptionally strong and diverse pedagogy and exercises. As a reference tool for users, the book is invaluable, a rich and diverse source of information in one convenient volume.
