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.

   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.
