Run script at startup

To make the script run at startup, follow these steps. This will run the script in a detached screen.

1. Create a folder startup at ~ or run mkdir ~/startup
2. Create a file with nano startup.sh
3. Copy the following content

#!/bin/bash

# Start speedtest-display
cd ~/speedtest-display/
python3 run-speedtest-display.py
exit

4. Make the script executable with chmod +x startup.sh
5. Install screen with sudo apt-get install screen
6. Open sudo nano /etc/rc.local
7. Paste su - pi -c "screen -dm -S pistartup ~/startup/startup.sh". This runs your startup script with every boot in a detached screen.
8. Reboot with sudo reboot to take effect.
