Came here while testing an IPv6 related sys/net/rtsock.c diff: all invocations use `-q' and route(8) says
-q Suppress all output. so the redirection is duplicate. If route still prints to standard output despite the quiet flag I want to see such a bug and fix it. Note that this does not involve standard error which is neither effected by `-q' nor redirected. OK?
