Using systemd

Note that systemd is available only from the Jessie versions of Raspbian OS.

To use systemd to start a program at boot up you need to create a .service file.

sudo nano /lib/systemd/system/chicken.service
Description=Chicken Service

ExecStart=/usr/bin/python /home/pi/bin/coop


Press Ctrl o and save then Ctrl x to exit

sudo systemctl daemon-reload
sudo systemctl enable chicken.service
sudo reboot
