What is a PL file?

A PL file is a script written in Perl that is compiled and run using a Perl interpreter. It contains lines of Perl program code with variables, operations, functions, and comments. PL files may be difficult to read due to the brief and compact nature of the Perl language syntax.

More Information

PL scripts are commonly used to create programs that parse text using regular expressions, but they also are used for a wide variety of other applications, including server scripting and Web server CGI scripts. PL files typically start with the line #!/usr/local/bin/perl, which tells the computer to run the script using the installed Perl interpreter.
