Take, for example, Sheer's discussion of the /etc/passwd file, which is at the core of user authentication. He provides a listing of a typical /etc/passwd file, then explains what each element on each line is for. This leads smoothly into a discussion of /etc/shadow, the shadow password file, and its capacity for hiding passwords behind a one-way hash algorithm. Sheer's prose is unfailingly clear and detailed, which is good because he's chosen to omit graphics altogether (which means, incidentally, that this book focuses on the command shell--bash, to be precise--and even the chapter on X Windows lacks screen shots). Aside from a few weird typographical choices (a tiny picture of a penguin invariably follows the word "Linux" in body text, for example), this is a faultless book.--David Wall
Topics covered: How to be a competent Linux user, familiar with the command line, key utilities like "sed," and important related skills like C programming, shell scripting, and regular expression creation. There's coverage of server software--notably HTTPd, Sendmail, and Exim--and coverage of the PostgreSQL server.
