Designed to allow UNIX programmers and users to get up to speed with the public domain interpreted language, this guide assumes some basic programming experience, demonstrates each function, and compares Perl statements to C, shell, or awk scripts. (Intermediate).
This is among the better programming books I've ever seen. What sets this apart is the focus on example code and the subsequent breakdown of the nuances of the code. I have plenty of other programming experience, but Perl has never been something in which to invest time until recently, and I think this is an excellent reference for the practitioner, and introduction for the neophyte. Every programming tool deserves this treatment.
Probably the best book on Perl I've come across. Every single topic is illustrated with examples. I typed out most of the examples by hand and ran them and it was great for learning. I'll definitely read more of her books on other programming languages.
