Don't forget to make it executable...
sudo chmod +x /usr/local/bin/MQTTstats.sh
The cron job
Add this line by editing roots crontab
sudo crontab -e
& add this line at the end:
* * * * * /usr/bin/mosquitto_pub -h broker.domain.tld -t `hostname` -m "`/usr/local/bin/MQTTstats.sh`"
replace broker.domain.tld with the address of your broker
(Yes... It's true... If you haven't yet installed the Mosquitto Clients, it's not gonna work... :P )
