Automatically start long-running script on boot and keep it running with systemd

README.md

1. Create EXAMPLE.service in /etc/systemd/system/

2. Modify service script as necessary

• ExecStart is the command to run on startup
• ExecStop is the command to run on shutdown
• Restart=always tells systemd to try to restart the script after 30 seconds if it exits for any reason

3. Tell systemd to start this service automatically when the machine starts:

sudo systemctl enable EXAMPLE.service

4. Start the service right now (optional):

sudo systemctl start EXAMPLE.service

5. Check the status (optional):

sudo systemctl status EXAMPLE.service
