Perl
Perl is a language that takes the best from other programming languages such as BASIC, Lisp, C and the Unix tools sed, AWK and shell. It is particularly suited for Unix systems programming, text processing and gluing heterogenous programs together. Its interpreter is called perl. Perl has seen five major revisions, and a sixth is currently worked on.
