The easiest way to do this is to include a shell script in /etc/bash_completion.d/. The basic structure of this file is a simple function that performs the completion and then the complete invocation which is a bash compiler. Instead of going into detail on how to use complete, I suggest you read an Introduction to the Bash Completion . Part 1 covers the basics and Part 2 goes into how you would write a completion script.
