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 modifica-
     tions up to that point  will  be  saved.   See  sync(2)  for
     details.

NOTE
     If you have done a write to a file on a remote machine in  a
     Remote  File  Sharing  environment,  you  cannot use sync to
     force buffers to be  written  out  to  disk  on  the  remote
     machine.  sync will only write local buffers to local disks.
