sync(1M)                                                              sync(1M)



NAME
     sync - update the super block

SYNOPSIS
     sync

DESCRIPTION
     sync executes the sync(2) system primitive.  If the system is to be
     stopped, sync must be called to insure filesystem integrity.  It flushes
     all previously unwritten system buffers out to disk, thus assuring that
     all file modifications up to that point are 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 only writes local buffers to
     local disks.
