On debian this is the default behavior.

Same in Ubuntu.

Bash completion on Ubuntu/debian is out of this world. I can do things like

lxc exec <TAB>

and get a list of currently running containers.

Fun fact: Ubuntu is a derivative of Debian!

[panpanna]

Yeah, but they also have added some stuff that is not part of standard Debian.

git has a whole bash library for autocompletion stuff (like complete ref, complete tree). You can even use it when writing your own commands.
