Software - Default Packages Uninstalled

Generate a list of packages installed...

sudo dpkg --get-selections | grep -v deinstall > ubuntu-files

This line searches for a particular installed package (from the command above), sends it to awk to get the first column, then sends that to the command xargs, which sends it to apt-get purge...

grep 'bluez' ubuntu-files | awk '{ print $1 }' | xargs apt-get purge

It will stop and list the packages it would have removed. If you are happy with this list, then add the option --yes to the line and it will uninstall the items...
