37.1 What We Do and Don't Tell You About Perl

Unlike most of the chapters in this book, this one really doesn't say very much about what Perl does or how to use it. perl (the program) is quite easy to use; Perl (the language, for which perl is an interpreter) is also easy to learn, especially if you know some of the other tools that it is designed to replace. However, it is also quite large and complex - sufficiently so that even the quick reference treatment we gave to sed ( 34.24 ) would be difficult to fit in here.

The CD-ROM contains the latest Perl version, Perl 5, and you can read about the new benefits of that version ( 37.5 ) .

Throughout the book, you'll find sprinkled a few Perl scripts.
