Can anyone please give an example of running a cron job for BFGminer on RPI to close and reopen every hour.

i have a sh file with this in

#!/bin/bash
./bfgminer --scrypt -o stratum+tcp://hub.miningpoolhub.com:20460 -u xxx.miner1 -p miner1,d=128 -S ALL --set MLD:clock=600

Any help for a Linux noob would be great, a lot of people i know with RPI are having issues with the moonlanders randommly just hash at 0 mh/s until the software is restarted.

Kind Regards

Paul
