Very occasionally a book is written about or for Unix System Administration, or Unix in general. If the author or publishers get the mix right it receives acclaim. Very, very occasionally one of those books achieves legendary status, by finding its way onto 98% of all Unix Sysadmins book shelves. This book is one of those legendary tomes. Just about every Unix Sysadmin I know has a copy of this sitting alongside books like Evi Nemeth's Unix Sys Admin Handbook. OK so it has a lot of information that isn't new to most sysadmins, but that's not where the beauty of the book lies. The real treasure is found in the countless nuggets of Unix info that have been long since forgotten, or yet to be learned. In my humble opinion, a true Unix Classic! If like me, you earn a living from Unix, then think of this book as a carpenter would his set of chisels. You don't use them for every job, but when needed, can prove invaluable.
