display some text at the end of a script

Question

At the end of my scripts I use often put "konsole" bash command, to know that the script is completed.
Now I'd like to add a text within the konsole (terminal), something such as "done!".
How should I do? What bash command I should add to my scripts?
I tried with konsole echo "done!", but usuccessfully.
Thank you!

Answer 1

Maybe it's better something like this (with zenity):

zenity --info \
--text="<span size=\"xx-large\">done!</span>" \
--title="you did it!" \
--display=:0.0

at the end of the script

Answer 2

Given you have accepted zenity pop-up as a solution, a similar result is possible with just:

notify-send "you did it!"
