Perl is a script programming language, which has a lot of similarity in syntax to “c” language. This also includes UNIX like sed;awk;tr etc. Perl is an interpreted language which can be assembled before execution in “c” code/bytecode. Once Perl is compiled, it is as fast as any other compiled “c” program. The Perl language is often considered as the best choice for the development of CGI (i.e Common gateway interface) due to its good text manipulation feature; even though it conducts only binary files.
