I discovered the Delete all module which gives you the ability to delete all the nodes of a given content type. However, with this module you can't delete a single node or a list of nodes.
In the question "Can I delete nodes of a given content type with Drush?" I found 2 answers talking about the command drush node_delete <nid>
but I can't find this command.
I found in a discussion about node_delete() some code using eval to accomplish this task, but it is using eval:
drush php-eval "global \$user; \$user = user_load(1); node_delete(nid);"
In case that there doesn't exist a functionality implemented to accomplish this, what is the better way to implement this functionality: in the Drush module or create a new module?
