How would I go about purge multiple directories that contain the word greys (Case sensitive)?
My initial idea was:
rclone --checkers 2 purge -vv -n --include "greys*" "gcrypt:/"
But in the dry run it didn’t say it would delete the right directories so I’m hesitant to run it.
Can someone give me the magic command I need to run in order to do it properly?
I don’t think purge uses wildcards based on the docs:
https://rclone.org/commands/rclone_purge/
I’d use delete and dry-run to make sure. I’d personally just use a mount and use a find command as that’s a bit easier if that’s possible for you.
I just mounted the remote on windows via:
rclone -vv mount gcrypt: Z:
I deleted the files, they went away. I closed down the mount process, relaunched it, and the files are still there. I checked on another machine with rclone lsd gcrypt: and they are still there. 
Okay, so since I had another machine with a mount, it didn’t like all the deletes and kinda I guess locked the files in a state where they’d show they were deleted but if you refreshed they were still there. All good now.
