You can get extended bash completion features if you source the file
/etc/bash_completion at terminal startup and/or login. I have it like
this in my .bashrc (this was already there but commented out):
if [ -f /etc/bash_completion ]; then
. /etc/bash_completion
fi
Then you can do things like
man ps<TAB>
and bash will complete for all commands that start with "ps" and have
manpages. It will then also know the options for many commands, e.g.
make-kpkg --i<TAB>
will give me "--initrd ", etc.
I have never done so myself, but I assume that you can set up your own
completion schemes as well.
The whole thing has one disadvantage: It leads to a slight but
noticeable delay every time bash is started. I guess that is the reason
why it is not enabled by default. (Knoppix has it activated, for
example.)
