Query: An introduction to Perl

This book is a gives a gentle introduction to Perll; by the time you have gone through this book, you would have touched on some very simple operations and common language idioms found in Perl. This is not a comprehensive guide; on the contrary the book is selective about covering only those constructs and issues that one is most likely to face early on in programming with Perl.This does not collect any of the more powerful feature in Perl like Reference; Data Structures; Manipulating lists of list.I would not recomend this book.
