I personally use a modified zbell (in zsh) to give me a notification when a command finishes after 30 seconds, and send me an email if it takes over 2 minutes.
I generally use Konsole's "notify when program exits" feature. For longer tasks, I have a small tool which I pipe to, and it sends me push notification with the output (if I prefer).
