A push button command to restart two systemctl services on a Raspberry Pi
This script utilises the GPIO pins on a Raspberry Pi to restart two running services (in this instance called 'log.service' and 'rigctld.service') at the push of a momentary button. I find this necessary because I use my Pi to syncronise rig information with CloudLog. However when I turn my radio off, often one or both of the services fail (because they're expecting a response from the rig), meaning they need restarting. In the past I had this script set to restart the Pi, but now I realise it is better all round to just restart the services instead of bouncing the whole Raspberry Pi.
In time I plan to add a command to sound a buzzer (attached to another GPIO Pin) which will serve as an audible confirmation that the services have been restarted.
To implement this script:
- Save the file (perhaps in
/home/pi/Scripts/?) $ sudo nano /etc/rc.local- Place this line before the final
exit 0-python /home/pi/Scripts/restartLog.py & $ sudo reboot
As ever, I offer this simple script for other people's interest and, perhaps, assistance.
Best wishes. 73 Michael GM5AUG
