shutting down in sh script don't work after exec [ RESOLVED ]

[MazHoot]

I'm trying to shut down raspberry pi when I close a program which is automatically started. I use it with a gamepad and when I quit the program, I would like to the rapsberry pi quit.

I have a pig.sh file located in /home/pi/.config/lxsession/LXDE-pi :

Code: Select all

#!/bin/sh
cd /home/pi/Desktop/lgpt/lgpt_DEB/bin
exec ./lgpt.rpi-exe
sudo shutdown -h now
sudo poweroff
sudo halt

As you can see I tried the 3 methods I found to shut down but none of these works. Lgpt.rpi-exe is successfully started, in fullscreen, but when I quit it, the raspberry pi is not shutting down, nothing happen.

pig.sh is started with autostart file in same folder which is like this :

@lxpanel --profile LXDE-pi
@pcmanfm --desktop --profile LXDE-pi
@xscreensaver -no-splash
@point-rpi
@sh /home/pi/.config/lxsession/LXDE-pi/pig.sh

I tried also inserting the shuting down command at the end of auto start file. If I do that, it works but it shut down just after pig.sh is started. It is supposed to do it only when I quit the program, not at startup.

The shell builtin command "exec" replaces the currently running shell with the command given as parameter: https://www.gnu.org/software/bash/manua ... l-Builtins
This means the lines after "exec" are unreachable. Run the command normally without exec if you want the script to continue after the command finishes.

That is normal behavior. Any commands put directly in autostart are all started at near the same time and are run independently.

It works!! Thank you!! I was stuck on this since several days! So I just removed "exec" (my command is sudo ./lgpt-rpi-exe and not exec sudo ./lgpt-rpi-exe) and it works.
