update - Periodically updates the file system
/sbin/update
The update command flushes data from memory to disk every
30 seconds. This ensures that the file system is up to
date in the event of a system crash. This command is provided
as a statically-linked executable in the /sbin
directory.
The setting of the smoothsync_age attribute of the vm kernel
subsystem overrides the default timing of the update
command. See sys_attrs_vm(5) for more information about
this attribute. Refer to the System Configuration and Tuning
and System Administration manuals for general information
about configuring and tuning the system.
