Isn't life grand? Here is Yet Another cool book, completely free, online and usable. This time, it is The Art of UNIX Programming, by Eric Raymond. Remebmer, FreeBSD is a Unix brethren, and most Unix books will work just fine as FreeBSD books, so that's yet another fertile source of information. I haven't used this book much, but it's gotten some nice reviews.
