From the Publisher
Programming Perl, second edition, is the authoritative guide to Perl version 5, the scripting utility that has established itself as the programming tool of choice for the World Wide Web, UNIX system administration, and a vast range of other applications. Version 5 of Perl includes object-oriented programming facilities. The book is coauthored by Larry Wall, the creator of Perl. Perl is a language for easily manipulating text, files, and processes. It provides a more concise and readable way to do many jobs that were formerly accomplished (with difficulty) by programming with C or one of the shells. Perl is likely to be available wherever you choose to work. And if it isn't, you can get it and install it easily and free of charge. This heavily revised second edition of Programming Perl contains a full explanation of the features in Perl version 5.003. Contents include: An introduction to Perl Explanations of the language and its syntax Perl functions Perl library modules The use of references in Perl How to use Perl's object-oriented features Invocation options for Perl itself, and also for the utilities that come with Perl Other oddments: debugging, common mistakes, efficiency, programming style, distribution and installation of Perl, Perl poetry, and so on.
