Remove all packages marked as rc by dpkg

Let’s see all the packages marked as rc by dpkg. Know more about the state rc. This state means that the configuration files are not yet removed. You can see how a single package can be removed.

$ dpkg --list |grep "^rc"
rc  bsh                                             2.0b4-10ubuntu2                                 Java scripting environment (BeanShell) Versi
rc  devicekit-disks                                 007-2ubuntu6                                    abstraction for enumerating block devices
rc  devicekit-power                                 011-1ubuntu2                                    abstraction for power management

rc  kdepim-runtime-data                             4:4.3.2-0ubuntu1                                shared data files for the KDE 4 base runtime

Let’s extract out the packages marked as rc

$ dpkg --list |grep "^rc" | cut -d " " -f 3

$ dpkg --list |grep "^rc" | cut -d " " -f 3 | xargs sudo dpkg --purge
