Remove all GNOME from debian - a one line

This one is not so easy to follow, but it works for me :-).

Do try only the stuff inside `` (back tick operator in the bash language), to see what it does:

$ aptitude remove `dpkg -l | grep gnome | sed 's/ii//g' \| sed 's/rc//g' | sed 's/^ *//;s/ *$//' \| sed 's/ \+ /\t/g' | cut -f 1`
