Rago (one of the Bell Laboratories developers who built UNIX System V, Release 4) updates the late Stevens' text on programming in the UNIX environment after some 13 years. He has updated the chapters on file input/output (I/O), files and directories, standard I/O library, system data files and information, process environment, process control, process relationships, signals, daemon processes, interprocess communication, network IPC (information processing center), terminal I/O, pseudo terminals, database libraries, and communicating with network printers. Rago has also added chapters on threads, multithreaded programming, and socket interfaces. Interfaces have been brought into line with the 2001 version of the POSIX.1 standard and case studies have been changed to cover more relevant real-world examples, most of which have been tested on the platforms of FreeBSD 5.2.1, the Linux2.4.22 kernel, Solaris 9, and Darwin 7.4.0 (the Free BSD/Mach hybrid underlying Apples Mac OS X 10.3).

This book is no superficial rewrite of the first edition. From cover to cover, it's apparent that Rago has carefully interpreted the original text and rewritten it to accurately reflect the changes of the past 13 years; he has also managed to preserve to original lucid and efficient presentation style of Stevens' classic.
