I understand Hungerburg to use it as follow: darkice-xy.sh start 3>&1 1>&2 2>&3 | grep -q "failed to write to ring ruffer" and not to check the Network. When the error occurs, then darkice-xy.sh stop sleep 2 darkice-xy.sh start Is this right? But how can I write the <if then clause> when the error was "greped"? Regards, Jörg
