UPDATE(VIII) 11/1/73 UPDATE(VIII)
NAME
update - periodically update the super block
SYNOPSIS
update
DESCRIPTION
Update is a program that executes the sync 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 should be executed out of the
initialization shell command file. See sync(II) for
details.
SEE ALSO
sync(II), init(VII)
BUGS
There is a system bug which, it is suspected, may be
aggravated by this program. Until further notice, update
should not be run.
