lookslikepat on "[Plugin: WP Super Cache] Manually delete the cache"

After trying it a few times I can't find any errors popping up. I added *.meta files to be deleted as well.
Here's my final ssh command:
ssh user@host "find /www/wp-content/cache/ \( -name '*.html' -or -name '*.html.gz' -or -name '*.meta' \) -delete"
