    @Tshepang: I guess you mean you want to learn how to write bash completion routines? Using bash completion is pretty easy, you just hit the tab key.

    How come this question is considered "too broad" ? That's ridiculous. It's perfectly valid, and answers provided prove it's not so easy to find out.

There aren't that many bash completion tutorials around, but this one is pretty good:

Introduction to Bash Completion

  • Part 1 is for general knowledge
  • Part 2 covers creating scripts in /etc/bash_completion.d/

I would start by looking at the library of bash completions already put together by the folks here:

http://bash-completion.alioth.debian.org/

They also have a mailing list:
