Unix Programming.
Third Edition.
Intermediate Level Users.
This third edition has not only been updated for Perl 5.6, but has also been rewritten from the ground up to reflect the needs of programmers learning Perl today. Informed by their years of success at teaching Perl as consultants, the authors have re-engineered the book to better match the pace and scope appropriate for readers trying to get started with Perl, while retaining the detailed discussion, thorough examples and eclectic wit for which the book is famous.
This edition includes an expanded and more gently-paced introduction to regular expressions, new exercises and solutions designed so readers can practice what they've learned while it's still fresh in their minds, and an overall reworking to bring 'Learning Perl' into the new millennium.
Perl is a language for getting your job done. Other books may teach you to program in Perl, but this book will turn you into a Perl programmer.
