Démarrer un script Python automatiquement :

Sous Ubuntu : https://stackoverflow.com/questions/24518522/run-python-script-at-startup-in-ubuntu

  • Copier le script Python dans /bin:
    • sudo cp -i /path/to/your_script.py /bin
  • Ajouter un Cron Job :
    • sudo crontab -e
    • Scroll to the bottom and add the following line (after all the #'s) :
      • @reboot sudo python3 /bin/your_script.py &
    • The “&” at the end of the line means the command is run in the background and it won’t stop the system booting up.
  • Test :
    • sudo reboot
