Sams Teach Yourself Perl in 24 Hours teaches readers new to Perl the necessary basics of Perl and then shows them how to apply that knowledge in real-world Web development.

The book is divided into three sections:

  • The first third of the book teaches the basics of the Perl language.
  • The second third of the book builds on this foundation, and shows the reader how to interact with the file system, operating system, and network.
  • The last third of the book focuses on Web development.It begins with the basics of CGI and then moves quickly into building common Web solutions such as data collection, multi-page forms, e-mail forms, and using Perl as a Web templating system.
