UPDATE(8)                            BSD                             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 ensures 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.
