Shut Down Icon

How can I add a shutdown icon to the desktop?

This thread at Questions has a method, but the thread is old, there must be an easier way now:

https://www.linuxquestions.org/question … op-868910/

I am setting up a machine for my 87 year old father (his old pentium with 256 MB just isn't cutting it anymore) and everything needs to be very simple.

Thanks,
JP.

Re: Shut Down Icon

Right-click on the desktop and select the "Create Launcher" option. Add the following:
- Name = Shutdown
- Comment = Shutdown the computer
- Command = xfce4-session-logout -h
- Icon = <select one that suits>

Re: Shut Down Icon

You can issue the command:

shutdown now

You can also suspend with

systemctl suspend

I've put these into scripts, and the added them to the panel so that I can click on them to shutdown or suspend the computer. I've even modified the shutdown icon to make it similar but distinctive for suspend. I can also call the scripts from other scripts, such as backup or moving files or other tasks that take time.

In the suspend script, I've added a preceding line printing out the current date and time, and a superseding line prompting to press a key to exit. That way it leaves a terminal window open so that when the computer wakes from the sleep state I see what the date and time was I suspended it.

I've also written another script where I prompt for a delay in suspending.  It then posts a notification window every so often as the suspend time is approaching, and plays a sound. That full code is:

#! /bin/bash
#strict BASH protocal
#set -euo pipefail
set -u
IFS=$'\n\t'

######################################################

# expand aliases to work when a prompt is not sent to the terminal
# e.g. sounds

if [ -f $HOME/.bashrc_aliases ]; then
	shopt -s expand_aliases
	source "${HOME}/.bashrc_aliases";
fi

######################################################

declare gap_sec=$(( ${gap_min}*60 ));
declare local_message;

notify-send "${local_message}" &

date;

paplay /usr/share/sounds/KDE-Im-Contact-Out.ogg &

systemctl suspend

read -n 1 -s -p "press any key to end." tempvar;

You may have different sound files and/or preferences, so modify it accordingly.
