NAME
update - periodically flush filesystem buffers.
SYNOPSIS
update [ options ]
DESCRIPTION
The update daemon flushes the filesystem buffers at a reg-
ular interval. It has two modes of operation. By default
it will wake up every 5 seconds and flush some dirty
buffers. If this is not possible, it will automatically
fall back to the traditional behavior of waking up every
30 seconds to call sync(2).
The following options are accepted by update:
-S Use the traditional behavior of calling sync(2)
even if the preferred method of flushing is possi-
ble.
-s secs
If using sync, wake up and call it every secs sec-
onds. The default is every 30 seconds.
-f secs
Unless using sync, wake up and flush some buffers
every secs seconds. The default is every 5 seconds.
update should be started as early as possible during the
boot process. If it is invoked by a non-privileged user,
it calls sync and exits.
