I just wanted to share what I found through an article in OReilly

Suppose if there is a command which you have to execute on your GNOME
terminal and it would take lot of time, and you would want to get on
with working on other jobs (but would want to be notified when your
command has finished executing its job), then you can you something
$ find . -print > /tmp/list.out && xmessage -nearmouse Find command executed
In this case you would be notified on a small popup window, such as a
message box, with the text which you have given, in this case "Find
There may be other ideas too, through which you want to be notified, I
feel this is somewhat simpler.
