I have nothing to say on the Sams book (having not read it) except that, without fail, I found any "teach yourself x in 24 hours" book that I have looked at to be full of mistakes and misleading flashy examples. Invariably things would be done in an "easy" and hacky way. Extrapolating from that I can only surmise (again, I've not read or even looked at this one), that quite probably learning from this book will end up with you writing the kind of Perl code that has been getting a deservedly bad reputation over the last years.

Compared to the Camel Book

This I do have something to say about. When you're a beginner, the Camel book is probably(*) not the right book to start with, you should rather pick up the Llama, which is expressly designed to teach a beginner Perl in easy steps with lots of examples to learn by. The latest edition just came out half a year ago, so it's pretty up-to-date on how and how not to write Perl. The Camel can then be used to understand why certain things work the way they do and become a real "guru" (though much the same can be done by reading the perldocs).

(*)Unless you are one of those unfortunate people who (like me) need to understand how stuff works from the inside before being able to use them in any useful way. For me, reading the Camel alongside, and sometimes ahead of, the Llama was the way to go. YMMV.
