How to assign a keyboard shortcut to show an Ubuntu Desktop notification?

Question

What I am trying to do is, I have a few texts in a file & when I tap a key combination like ctrl+Q, the text should appear as a notification on my Ubuntu Desktop. What is the command to assign this keyboard shortcut?

Answer 1

You can use the notify-send tool:

cd $HOME
touch foo
echo "foo\nbar\nbaz" > foo
notify-send "TEST" $(cat ~/foo)

it will create a notification like the one below:

Finally read How to add keyboard shortcuts? to enable Ctrl+Q for this notification (or better choose another combination as this one is already occupied - Thanks Jacob Vlijm).

Update:

All you have to do now is to create a small launcher (foo.sh):

#!/bin/bash

notify-send "TEST" $(cat ~/foo)

Change its permissions:

chmod 777 foo.sh

And assign to your new shortcut the full path of your launcher:
