Origin: System V
Remarks: Not supported on the Integral Personal Computer.
DESCRIPTION
Sync executes the sync system intrinsic. 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.

REDUCED SEMANTICS
If sync(2) is a no-op and the system is RUN ONLY or NUCLEUS, the sync command need not be present.
