System Administration Commands                           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 modifica-
     tions up to that  point  will  be  saved.  See  sync(2)  for
     details.
