I'm doing a project where raspberry pi runs headless. I have written two python programs, one for swiching off the raspberry pi via gpio push button and the other is a opencv-python program. I need to run both the programs at startup and both are endless scripts . The first program shutdown rpi safely when the button is pressed and other does image processing. How to run both automatically when rpi is started ?

  • Not sure what to do, both are endless scripts. will putting python p1.py & python p2.py & in /etc/rc.local work ?

  • I'd either do that or add it as a reboot cron job. Whatever you try make sure you give the full path to the script, e.g. not p2.py but /home/pi/p2.py.

  • If you put them in /etc/rc.local and they are persistent, make sure you fork them, e.g. p1.py &.

Use either crontab -e and append @reboot path/to/script or navigate to /etc/rc.local and put it in there like this script.py &.

Look into using Supervisor to manage your scripts. It is available as a package for Raspbian.

Supervisor can restart the scripts if they crash and capture any the output and log it. It can also run the script as a non-privileged user if you want.

You can use cron:

crontab -e

and append:

@reboot path/to/your/script

This approach doesn't restart your scripts if they exit with an error, though.
