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).
