MirOS Manual: update(8)

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

NAME

     update - flush internal filesystem caches to disk frequently

SYNOPSIS

     update

DESCRIPTION

     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 obtained by using the sync(8) command, although
     the in-kernel update process will do this in a staggered manner.

HISTORY

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

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

BUGS

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