We can also use Drush to remove permissions using the drush role-remove-perm command and pass arguments for the role and the permission name that we want to remove.
We can finish up this exercise by removing the 'administer comment types' permissions that we previously added by executing the following command in a terminal window:
drush role-remove-perm developer 'administer comment types'

By now, we should be getting comfortable with using Drush to execute various commands against our Drupal instance without the need to use the Admin UI.
