Perl by Example, Third Edition—This Book Is a Superb, Well-Written Programming Book
Praise for Ellie Quigley’s Books “I picked up a copy of JavaScript by Example over the weekend and wanted to thank you for putting out a book that makes JavaScript easy to understand. I’ve been a developer for several years now and JS has always been the ‘monster under the bed,’ so to speak. Your book has answered a lot of questions I’ve had about the inner workings of JS but was afraid to ask. Now all I need is a book that covers Ajax and Coldfusion. Thanks again for putting together an outstanding book.” —Chris Gomez, Web services manager, Zunch Worldwide, Inc. “I have been reading your UNIX® Shells by Example book, and I must say, it is brilliant. Most other books do not cover all the shells, and when you have to constantly work in an organization that uses tcsh, bash, and korn, it can become very difficult. However, your book has been indispensable to me in learning the various shells and the differences between them…so I thought I’d email you, just to let you know what a great job you have done!” —Farogh-Ahmed Usmani, B.Sc. (Honors), M.Sc., DIC, project consultant (Billing Solutions), Comverse “I have been learning Perl for about two months now; I have a little shell scripting experience but that is it. I first started withLearning Perl by O’Reilly. Good book but lacking on the examples. I then went to Programming Perl by Larry Wall, a great book for intermediate to advanced, didn’t help me much beginning Perl. -
