What Others Think

Isn't this what 'apt-get purge --auto-remove' or 'dpkg -Pa' does? Also, why are you using grep|awk? This is more clean: dpkg -l |awk '/^r/ {print $2}' Also, since aptitude just calls apt, which just calls dpkg, why not (assuming that you have config files left over after a package remove and that you're trying to clean up creft that apt-get and dpkg aren't catching on their own): dpkg --purge `dpkg -l |awk '/^r/{print $2}'` You clearly are learning/understanding the shell, but you should read a little about useless use of grep (and maybe cat, too): http://partmaps.org/era/unix/award.html
