OK! YEA!
I search in google for BASH_COMPLETION_DIR and found this:
http://www.unixwerk.de/linux/slack/bash_completion
I search a fedora package for this. I found that a bash-completion in my apt-get, I installed it and its work!
This package is from here:
rpm http://apt.sw.be redhat/fc1/en/i386 dag

I hope it is also so easy in debian.

Thank you!
