UNIX System Administration Handbook ^{2nd Ed.}

This sweeping revision of the world's most comprehensive guide to UNIX system administration is an ideal tutorial for those new to system administration and an invaluable reference for experienced UNIX professionals. Using a practical, hands-on approach, UNIX System Administration Handbook, Second Edition, covers every aspect of system administration — from basic topics to UNIX esoterica — and provides explicit guidelines for dealing with the six most popular versions of the UNIX operating system.

This edition is accompanied by a CD-ROM containing a wealth of valuable system administration tools, freely-available software, standards documents, and configuration examples that will prove indispensable to any UNIX administrator.

This book is a worthwhile addition to any UNIX professional's library. It offers:

• A Practical Approach. This book provides numerous war stories and a wealth of pragmatic advice.
