HEX8A1 economy / high efficiency mode switch depending on condition

[idonothave]

Hi,
I am looking for solution of the situation I have. I would like to run HEX8A1 unit with different configuration file during the day. It would be switched between two config files automatically depending on if reference IP in the network is running or not. I see solution to run the script which ping reference IP and if it is alive then change configuration file of cgminer and restart it. But at the moment I am not able to write the script easily. Anybody interested or was it already solved?
