It will take a stream so you can use: aucat -o - | lame -r - - | ezstream -c ezstream.xml If you throw it into rc.local you will have to disconnect it from the terminal for it to work. /etc/rc.local: /usr/bin/aucat -o - 2> /dev/null | /usr/local/bin/lame -r - - | /usr/local/bin/ezstream -q -c /etc/ezstream.xml < /dev/null &> /dev/null or I've dumped it into a script aucat | lame | ezstream echo $! > stream.pid to use pid checking instead of that ps grepping (killing the ezstream will terminate the entire command set) and then you can also use an rc.d script daemon="script" daemon_user=_no_priv daemon_flags=</dev/null &> /dev/null" Funny story, I'm working on something similar and will shortly have a question for misc too - watch for it as aucat is giving me some trouble.
