SYNC(1M)              (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.
