It's no coincidence that UNIX is a four-letter word-- the 'problem child' of operating systems is notoriously arcane and inscrutable. In 'The Underground Guide to UNIX', scrutability expert John Montgomery takes you on an emotional roller-coaster ride through the vagaries of this hard-to-master yet incomprehensible operating system. You'll find serious information on getting the most out of the parts of UNIX you use every day, as well as detailed advice on working better and faster, whatever flavor of UNIX you're stuck with... uh, prefer. You'll laugh, you'll cry, you'll buy copies for every room in the house. (NOTE TO EDITOR: too blatant?) Learn how to: master the most popular UNIX text editors: vi, emacs, ex, and sed; use and abuse basic UNIX security-- hide potentially incriminating files like love.letter or resume.doc, or search your boss's files for your name and key words like 'problem employee'; access the Internet and use ftp, telnet, gopher, and Mosaic to get completely frivolous information from almost anywhere in the world; program the shells (C, Korn, and Bourne) to do whatever the heck you want; and oh so much more! Every page has something you can use immediately. This book is packed wall to wall with advice, warnings, tips, bug reports, workarounds, and the kind of nitty-gritty explanations that could come only from someone who eats, sleeps, and breathes UNIX. This lively, irreverent book gives straighforward advice on the best way to perform any task in the UNIX environment. Regardless of the UNIX version used by the reader, John Montgomery unlocks the mysteries of the file system and covers all the essentials for exploiting the power of the UNIX operating system. For practical advice on everything from customizing any UNIX environment, to preventing and surviving common UNIX disasters, this book is fun for serious users.
