Rclone is a command-line program to manage files on remote storage.

Some handy commands.

rclone config
rclone listremotes

rclone ls  --min-age 30d REMOTE:/folder/path/
rclone lsf  --max-age 7d REMOTE:/folder/path/

rclone delete --min-age 30d REMOTE:/folder/path/ --dry-run
rclone rmdirs --min-age 30d REMOTE:/folder/path/ --dry-run

There's also a purge option that deletes /folder/path/ and everything in it and does NOT honor your –mind-age command.
