UPDATE(8)                   System Manager's Manual                  UPDATE(8)



NAME
       update - periodically update the super block

SYNOPSIS
       /usr/etc/update

DESCRIPTION
       update  is  a program that executes the sync(2) primitive every 30 sec-
       onds.  This insures that the file system is fairly up to date  in  case
       of  a  crash.  This command should not be executed directly, but should
       be executed out of the initialization shell command file.

SEE ALSO
       sync(1), sync(2), init(8)
