This is a book on the widely used programming language, Perl. It includes both descriptions of the features of the language, and how they can be used to write useful programs. As is usually the case with books on programming, the examples are small and are designed to illustrate one or a few language capabilities. Larger, more complex programs often drown the features the book is trying to show, just by their size and structure. The goal of the book is to provide a clear and concise description of Perl for someone who has programmed in some other programming language and wants to learn to use Perl. In many ways, Perl is similar to other programming languages; in some other ways, it is very different. We point out, whenever it is relevant, the advantages Perl offers over alternative languages. Perl has been for some time the most widely used UNIX system administration language. It is now also the most popular scripting language for writing CGI.
More and more companies are using Perl as their language of choice for projects great and small in large part because of Perl's popularity among web CGI programmers. Perl's ability to quickly generate and manipulate text files, along with its flexibility in communicating with a variety of systems and platforms, make it indispensable. In many organizations, however, especially those with large-scale programming teams, Perl adopters still fight a daily battle for acceptance. Perl is perceived by the IT managers in these organizations as difficult to manage (because there's no one way to program), impossible to maintain (because deployment does not require compilation), prone to error (because its variables are weakly typed), and maybe even dangerous (because hackers use it). Applied Perl tackles these misperceptions through exploring cases where Perl is being applied inventively in the film industry, financial community, and Internet community.
Perl is an immensely popular scripting language that combines the best features of C, key UNIX utilities and a powerful use of regular expressions. It has a wide range of uses beyond simple text processing and is commonly used for web programming - creating and parsing CGI forms, validating HTML syntax and hyperlinks - as well as e-mail and Usenet news filtering. Perl is increasingly the system administrator's scripting language of choice and is used for file and directory manipulation, database access and a whole range of daily system operator chores. Text takes the reader from installation, through the core language elements (regular expressions, references, modules, and the like), and on to basic applied techniques. Also covers how to access and work with databases in Perl and write CGI scripts to generate Web pages. Perl 5.6 is used in all the examples, and a handy reference section is included.
Now developers can learn how to write robust, secure, and efficient Common Gateway Interface programs for the Web. Ideal for DOS, UNIX, or Windows users since CGI is platform independent, the book contains an abundance of solutions to "real-world" problems, along with a helpful focus on CGI scripting. The CD-ROM includes source code and examples from the book. This book is one of the first books to provide comprehensive information on developing with CGI (Common Gateway Interface). It covers many of the aspects of CGI including, interactivity, performance, portability, and security. After reading this book, the reader will be able to write robust, secure, and efficient CGI programs. - Covers client/server programming, working with gateways, and using Netscape. Readers will master forms, image maps, dynamic displays, database manipulation, and animation. Also included is: Common Gateway Interface (CGI); HTML and Forms; and CGI Security.
