sync(1)                                                   sync(1)



     NAME
          sync - update the superblock

     SYNOPSIS
          sync

     DESCRIPTION
          sync executes the sync system primitive.  If the system is
          to be stopped, sync must be called to insure file system in-
          tegrity.  It will flush all previously unwritten system
          buffers out to disk, thus assuring that all file modifica-
          tions up to that point will be saved.  See sync(2) for de-
          tails.

     EXAMPLES
               sync

          should be typed to flush all internal disk buffers, before
          bringing down the system.

     FILES
          /bin/sync
