Unix in a Nutshell

It's been six years and more than 200,000 unit sales since our bestselling third edition of "Unix in a Nutshell" was released, and the very nature of "Unix" itself has evolved. Our new fourth edition has been reworked to tell the current story of Unix and highlight the strengths of this network operating system in its various flavours. In true O'Reilly Nutshell fashion, this book is chock full of reference information on system- specific utilities and administration tools. Readers will find plenty of information that's essential to the way Unix works in the world today.

Arnold Robbins, an Atlanta native, is a professional programmer and technical author. He has worked with Unix systems since 1980, when he was introduced to a PDP-11 running a version of Sixth Edition Unix. He has been a heavy AWK user since 1987, when he became involved with gawk, the GNU project's version of AWK. As a member of the POSIX 1003.2 balloting group, he helped shape the POSIX standard for AWK. He is currently the maintainer of gawk and its documentation. He is also coauthor of the sixth edition of "Learning the vi Editor" from O'Reilly.
