Want to purge all .nomedia files on my phone

It is a flaw in my opinion that Google Photos backup to Drive won't pick up items in folders with a .nomedia file in them. For example, WhatsApp sent images or videos. I've got a bash shell command to find and delete .nomedia files anywhere in my user-accessible part of the filesystem, of the form:

/ -name .nomedia -type f -delete

I've tried to set up a daily run job executing this command using Tasker, but I simply cannot get it to work.
