update(1m)                 DG/UX 4.30                  update(1m)



     NAME
          update - periodically update the super-blocks of mounted
          file systems

     SYNOPSIS
          /etc/update

     DESCRIPTION
          Update is a program that executes the sync(2) primitive
          every 30 seconds.  This ensures that mounted file systems
          are fairly up to date in case of a system crash.  Do not
          execute this command directly, but out of the initialization
          shell command file.

     SEE ALSO
          init(1m), sync(1), sync(2).
