Assuming you have configured bash as your linux shell (It has been the default under most distros for ages), then the config you want will be under /etc/bash_completion.d/

In there you will find a collection of shell scripts that bash uses to guess what you mean when you hit tab. A google search on "bash autocomplete" should find you some tutorals on how to write one of these scripts.
