I'm a trying to start a program at boot but without success. The program starts well but doesn't stay alive (it is supposed to be a infinite script). But when I start the program normally I don't have any problem! I don't get why when I run at reboot it doesn't work.
I use a cron tab like this:
@reboot sudo python /bin/gestion.py &
I can show you my code:
