purge all packages marked with 'rc'

After you install/remove lots of packages, there are many packages marked with 'rc'. This script help you to purge these packages, it will save some spaces from your disk.

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):
