CGI-BIN

The most common name of a directory on a web server in which CGI programs are stored. The “bin” part of “cgi-bin” is a shorthand version of “binary”, because once upon a time, most programs were referred to as “binaries”.

In real life, most programs found in cgi-bin directories are text files -- scripts that are executed by binaries located elsewhere on the same machine.

A cgi-bin directory will give you the privilege to execute cgi-scripts. CGI scripts are small programs which resides on a server. Example's of cgi-scripts are guest books, discussion boards, counters, and practically anything you can think of.

You can find most of these types of scripts free.
