update(8)
NAME
  update - Periodically updates the file system

SYNOPSIS
  /sbin/update

DESCRIPTION
  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.
