Raspberry Pi Single Shutdown Reboot and Startup Button

This script supports

  • Press and release for safe system reboot
  • Press and hold for 3 seconds for safe system shutdown

While this script can be used with any GPIO pin, to support startup after shutdown (Wake from Halt) connect one side of a simple momentary normally open switch to GPIO3 (physical pin 5) on the Raspberry Pi 2/3 and Zero models and the other side to ground - such as physical pin 6 or any other ground pin.

More information on this Wake from Halt function can be found at http://elinux.org/RPI_safe_mode#cite_note-1

No additional hardware other than a basic button is required as GPIO3 also has a physical pullup resistor.

Download

Download a local copy of the project from the Git website or as follows from the command line:

git clone https://github.com/tmccoy00/rpishutdown.git

Manual Installation

Assuming you are the user pi, add the following line in /etc/rc.local immediately before the line with exit 0. Be sure to include the "&" as this script runs in the background at startup.

python /home/pi/rpishutdown/shutdown.py &

Note that this script and installation example assumes you are the user pi with authority to run sudo with no password.

Example /etc/rc.local file with line inserted.

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

# Print the IP address
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
  printf "My IP address is %s\n" "$_IP"
fi
python /home/pi/shutdown.py &
exit 0
