I have an on_reboot.sh file that contains the following:


source /home/pi/.profile
workon cv
cd /home/pi/reboot
python pi_test.py

After that I made the file executable using

$ chmod +x on_reboot.sh

and then in my crontab I put the following to run it on boot:

@reboot /home/pi/reboot/on_reboot.sh

However, it is not working when the Pi boots up. When I run the sh file on the command line it is working fine. I tried modifying the crontab like this:

@reboot sudo su – pi bash -c ‘/home/pi/reboot/on_reboot.sh’

to run the startup script as user pi but is not working either. How can I fix this?

You should start your script as service with a systemd unit. It seems the script only runs one time and does not stay in the background. I don't know other edge conditions of your script but with this what I see I would define a unit file with:

rpi ~$ sudo systemctl edit --force on_reboot.service

In the empty editor insert these statements, save them and quit the editor:

Description=Script On Reboot



Edit again with sudo systemctl edit --full on_reboot.service.

Enable the service:

rpi ~$ sudo systemctl enable on_reboot.service


Check with systemctl status on_reboot.service

  • sir the script runs on reboot, but after 1 to 2 seconds it became off the script is not running anymore

  • Yes, that's because the script do things I don't know. It will connect to a server. What server? What connection? Python will output something. What output? Seems it is a graphical output.
