DESCRIPTION
   The tar command archives and extracts files to  and  from  a
   single  file  called  a tarfile. A tarfile is usually a mag-
   netic tape, but it can be any file. tar's actions  are  con-
   trolled by the key argument.  The key is a string of charac-
   ters containing exactly one function letter (c, r, t , u, or

k          Requires tar to use the size argument as  the
                  size of an archive in kilobytes. This is use-
                  ful when the archive is intended for a  fixed
                  size device such as floppy disks. Large files
                  are then split across volumes if they do  not
                  fit in the specified size.

示例：
