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.
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.
Paul W. Abrahams, Sc.D., CCP, is the author of TeX for the Impatient, a book whose success inspired UNIX for the Impatient. A consulting computer scientist and past president of the Association for Computing Machinery, he specializes in programming languages, design and implementation of software systems, and technical writing. He received his bachelor's degree in mathematics from the Massachusetts Institute of Technology in 1956 and his doctorate in mathematics there in 1963, studying artificial intelligence under Marvin Minsky and John McCarthy and writing his dissertation on "Machine Verification of Mathematical Proof". He is one of the designers of the first LISP system and also the designer of the CIMS PL/I system, which he developed while a professor at New York University. He also participated in the design of the Software Engineering Design Language (SEDL), developed at the IBM T.J. Watson Laboratories. Currently he is working on the design of SPLASH, a Systems Programming LAnguage for Software Hackers and on a new book, OS/2 for the Impatient. In 1995 he was honored as a Fellow of the ACM. Paul resides in Deerfield, Massachusetts, where he writes, hacks, hikes, hunts wild mushrooms, and listens to classical music. His Internet address is abrahams@acm.org.
