I have a custom post type called "meetings" and I will like to bulk remove all the posts and all of its attachment images...
Can this be done with the wp-cli?
Here's an example command to delete the featured images in the
meetings post type:
wp post list --post_type= meetings --fields=ID --format=csv | xargs -I % wp post meta delete % _thumbnail_id
You can use wp post meta list on a post to get the names of the fields you wish to delete and modify the command above accordingly.
