Files that contain the .pl file extension usually hold script that has been written in the Perl programming language. Perl is a high-level dynamic programming language that was initially developed in 1987 by Larry Wall.
Multiple PL scripts can be compiled and run using a Perl interpreter. PL files are commonly used to design applications that parse and analyze text as well as Web server CGI scripts.
It is very rare to see the .pl file extension used on the Web. This is due to the fact that the Perl scripts are normally run through web server CGI scripts when being used on the Internet.
