UPDATE(8)               OpenBSD System Manager's Manual              UPDATE(8)

     update - flush internal filesystem caches to disk frequently


     The update command no longer exists, but has been incorporated into the
     kernel where it will flush dirty buffers that have not been touched for
     thirty seconds or more.

     The same effect can be seen by using the sync(8) command, although the
     in-kernel update process will do this in a staggered manner.

     sync(2),  fsck(8),  init(8),  sync(8)

     It is possible on some systems, that a sync occuring simultaneously with
     a crash may cause file system damage. See fsck(8).

     An update command appeared in Version 6 AT&T UNIX.

     The update command was incorporated into the kernel in OpenBSD 1.2.
