This is an update of an absolute classic, and the definitive guide for UNIX programmers. Rago has done an excellent job updating this second edition to include topics important to modern UNIX programmers like POSIX threads. He has also done a masterful job updating the standards related material including updating all the examples and discussions for newer APIs. He has maintained the incredibly readable style of the original work. This is an absolute must have for any programmer that touches a UNIX system. I even recommend this book to UNIX admins and users. Go out and buy this book!
