Purge configuration files of removed packages on debian based systems

dpkg -P $(dpkg -l | awk '/^rc/ { print $2 }')
Removes the useless "grep" step present in many other solutions and tries to be as short and as fast as possible. A more elegant solution but longer and spawning one more process would be: dpkg -l | awk '/^rc/ { print $2 }' | xargs dpkg -P
Sample Output
(Reading database ... 48299 files and directories currently installed.)
