sync(1M)                                                 sync(1M)



     NAME
          sync - update the super block

     SYNOPSIS
          sync

     DESCRIPTION
          sync executes the sync system primitive.  If the system is
          to be stopped, sync must be called to insure file system
          integrity.  It will flush all previously unwritten system
          buffers out to disk, thus assuring that all file
          modifications up to that point will be saved.  See sync(2)
          for details.

     EXAMPLE
               sync

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

     FILES
          /bin/sync
