Perl is a programming language developed by computer programmer Larry Wall in 1987. It was first used as a Unix scripting language, but has since undergone several transformations to become one of the most popular programming languages. It is now used for a variety of tasks, ranging from system administration to web development. A Perl script or program is made up of one or more statements, which are written in the script in a straightforward manner.
Today, sites like Amazon.com, bbc.co.uk, Priceline.com, Craigslist and IMDb use Perl. It has even been used for other tasks like creating computer games, flight simulators and automated web photo galleries.
But how can you learn it?
There are several ways to start.
There are many web resources to use, starting with learn.perl.org. This site gives you a beginner’s breakdown of Perl, including directions on how to install it, basic programming practices, frequently asked questions and more. According to the website, there are also more than 107,000 modules ready for you to use. Perl modules are a set of related functions in a library file, designed to be reusable by other modules or programs.
The good news is that if you want to use Perl, it is compatible with any operating system – Unix, Windows, Apple – and with any Internet connection – cable, DSL or high speed satellite internet service.
