Thoroughly updated to account for recent developments, the Second Edition of UNIX for the Impatient is an in-depth, comprehensive guide to UNIX - a handbook you can use both for learning and as a ready reference. Clear, concise, and readable, the book is written for the technically oriented UNIX user who doesn't want to wade through verbose tutorials, but isn't already an expert.

Its functional organization makes it easy to find the right tool for any task, with a complete alphabetical summary providing fast lookup of commands, options, and subcommands. An extensive discussion of underlying UNIX concepts, supplemented by a glossary, enables even a UNIX beginner to penetrate the mysteries of UNIX terminology.

1. The Second Edition is based on the IEEE POSIX.2 Standard now widely adopted by UNIX vendors and implementors. Descriptions of commands and facilities have been extensively revised to conform to the POSIX specifications and extended to cover the entire set of POSIX.2 user utilities. As before, important System V, BSD, and GNU variations and enhancements are also presented.
