thankyou martin I think I've cracked it now (the hard way) monit appeared to be interested only in '/etc/init.d/<whatever> start' so I created the script /etc/init.d/stream and the command '/etc/init.d/stream start' worked. I now have monit working and auto-restarting the ffmpeg process when it (often) goes down. Now I just have to tweak it so monit checks the process more than once a minute.
