SYNC(8)                 OpenBSD System Manager's Manual                SYNC(8)

     sync - force completion of pending disk writes (flush cache)


     Sync can be called to insure that all disk writes have been completed be-
     fore the processor is halted in a way not suitably done by reboot(8) or
     halt(8).  Generally, it is preferable to use reboot(8) or halt(8) to shut
     down the system, as they may perform additional actions such as resyn-
     chronizing the hardware clock and flushing internal caches before per-
     forming a final sync.

     Sync utilizes the sync(2) function call.

     sync(2),  fsync(2),  halt(8),  reboot(8),  update(8)

     A sync command appeared in Version 6 AT&T UNIX.
