sync(1M)              UNIX System V(Essential Utilities)               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.
