What's wrong with "subtract 'du -s backup_B' from 'du -s backup_A'"? If this isn't what you mean, then you need to explain it better. The concept of files being "in" a directory is just a convenient fiction. Both backup_A and backup_B are just sets of hard links. poc -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
