What is the custom command to "Show Desktop" for hot corners?

Question

I wanted to have a "Show Desktop" like in the windows ( when I point the mouse to bottom right corner it will show the desktop )

Answer 1

As far as I know, there is no way to run a command after leaving a hot corner, but you can toggle "Show Desktop" when you touch a hot corner.

I've got the following script from this article:

1. You first need to install wmctrl (sudo apt install wmctrl)
2. Save the script:

#!/bin/bash
status="$(wmctrl -m | grep "showing the desktop" | sed -r 's/(.*)(ON|OFF)/\2/g')"

if [ $status == "ON" ]; then
wmctrl -k off
else
wmctrl -k on
fi

3. Make it executable: chmod +x /Path/to/script.sh
4. Set the command for the hot corner to /Path/to/script.sh

This will check if the desktop is currently shown and toggle it using wmctrl:
