UPDATE(8)                                               UPDATE(8)

     NAME
          update - periodically update the super block

     SYNOPSIS
          /etc/update

     DESCRIPTION
          Update is a program that executes the sync(2) primitive
          every 30 seconds.  This insures that the file system is
          fairly up to date in case of a crash.  This command should
          not be executed directly, but rather out of the initializa-
          tion shell command file rc(8).
