Daniel J. Barrett has been immersed in Internet technology since 1985. Currently, he is working as a software engineer. He is the author of O'Reilly's Linux Pocket Guide, and the coauthor of two more O'Reilly books: Linux Security Cookbook, and SSH, The Secure Shell: The Definitive Guide.
If you use Linux in your day-to-day work, this popular pocket guide is the perfect on-the-job reference. The third edition features new commands for processing image files and audio files, running and killing programs, reading and modifying the system clipboard, and manipulating PDF files, as well as other commands requested by readers. You'll also find powerful command-line idioms you might not be familiar with, such as process substitution and piping into bash.
