       CAUTION: shred assumes the file system and hardware overwrite data in
       place.  Although this is common, many platforms operate otherwise.
       Also, backups and mirrors may contain unremovable copies that will let
       a shredded file be recovered later.  See the GNU coreutils manual for
       details.
