SYNC(1)			 HP-UX 5.0		       SYNC(1)

     NAME
	  sync - update the super block

     SYNOPSIS
	  sync

     HP-UX COMPATIBILITY
	  Level:    HP-UX/NUCLEUS

	  Origin:   System V

     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.

     SEE ALSO
	  sync(2).

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