Media praise for Essential System Administration Pocket Reference
"A must have for anyone who has to maintain a Unix machine and is valuable even as a shortened collection of man pages. Add to this the additional help, categorization, and the fact that you can easy keep it with you and it becomes my new indispensable Linux companion."--Peter Sheehan, The Assayer, Feb 2003
"[Consumers] will find the fine 'pocket references' produced by O'Reilly to be compact and affordable."
-- , The Computer Shelf: Midwest Book Review
"Unless you have memorized every command and its options and variations across the different Unix systems, the pocket reference is something I would highly recommend getting."--Linh Pham, Daemon News, Jan 2003
