Mastering Unix is targeted at those using one of the three most popular Unix renditions (Solaris, FreeBSD, and the ubiquitous Linux), and it is a real strength of the book that Linux and open source are properly explained and contextualized.

The history of Unix is briefly but fully walked through, and then the book describes the OS's structure and how it uses files and directories. Scripting is covered (the focus is on the bash shell, other shells are given comparatively short shrift), and a useful overview of differing text editors is covered. The writing is clear throughout and the examples useful and illuminating. Despite the book's size, the text never feels exhaustive, and although this may not be the only Unix book to consider having on your desk, it should definitely be among them.

The particularly useful CD-ROM contains the Gnome and KDE desktop environments and a number of Unix servers and utilities, including Samba, Apache, Sendmail, GNU Emacs, Perl, and NEdit. --Mark Thwaite, Amazon.co.uk
