After reading this book I have found it quite easy to start picking up the basics of Perl which as ugly as the language might be I am finding to be quite powerful. Of course if you already program in Perl then you already know this.
The book focus on the basics to get you started and has great footnotes. It is a rather small book which not including the Appendices is only about 240 pages. So if you are interested in learning Perl I do find this book to be a great place to start.
Check it out and let me know what you think.Â Learning Perl, 5th Edition
