Shutdown and Power Off Delay

[Techstyle]

I added a script to the Shut off text in /boot/firmware/config.txt per the process below.  This allows a delay to quietly close OpenCPN and Chromium.  Could this be automated and added to the options in "Raspberry Settings"

Use the Settings app, Raspberry Settings.  Set as below:
 
   
 
After this do the following:
 

1. Create a new script file:
   

Code:

sudo nano /usr/local/bin/custom_shutdown.sh

 

1. 2.  Add the following content to the script:

 

Code:

#!/bin/bash

# Kill Chromium
pkill chromium

# Kill OpenCPN
pkill opencpn

# Wait for applications to close
sleep 5

# Shutdown the system
shutdown -h now

1. 3. Make the script executable:

 

Code:

sudo chmod +x /usr/local/bin/custom_shutdown.sh

 

1. 4. Modify the GPIO shutdown configuration to use your custom script. Edit the /boot/firmware/config.txt file:

 

Code:

sudo nano /boot/firmware/config.txt

1. 5. Find the line that enables GPIO shutdown and modify it to use your custom script:

 

Code:

dtoverlay=gpio-shutdown,gpio_pin=21,active_low=1,gpio_pull=down,gpio_shutdown_command=/usr/local/bin/custom_shutdown.sh
