PERL

An acronym for Practical Extraction and Reporting Language, PERL is a robust programming language frequently used for creating CGI programs on web servers. PERL is faster than UNIX shell script programs, it can read and write binary files, and it can process very large files. The major advantage of PERL over C as a programming language is that PERL does not need to be compiled.
