Perl Training Develop a
Passion for learning.

What is Perl?

Perl is a general purpose dynamic programming language developed by Larry wall in 1987. Initially it was designed for scripting to make report processing earlier. But it evolved to be used for various purposes like CGI (Computer Generated Imagery), System administration, graphics programming and finance. Perl has been nicknamed “Swiss Army chainsaw of scripting languages” because of its power, flexibility and inelegance. Its evolution also created different languages (different versions with special features) with same name (Perl), only differentiated by a numeral after the name such as Perl 6. Many features of Perl are derived from other programming languages like C and Shell script (sh). Some of the important features are automatic memory management and data typing. Perl also supports Object Oriented Programming (OOP), first class functions and complex data structures. In the past, it was also referred as the "duct tape that holds the Internet together" with reference to its ubiquitous use as a glue language. Perl is available for all major operating systems (as MacPerl for Mac OS) and can be downloaded from CPAN (Comprehensive Perl Archive Network), a public and free website.
