Can I delete nodes of a given content type with Drush? Just wondering if Drush is capable of deleting nodes of a given content type. 

Something like: $ drush delete-node --type=MyContentType

If not possible, can I create a method like that?
Install the devel module, and use drush to delete all the nodes,

$  drush genc --kill 0 0 


You can also give a type option,

$  drush genc --kill --types=article 0 0
