I have a slightly more advanced setup which uses post-command hooks to send a desktop notification when a command has been running for over 3 seconds. That notification contains the elapsed time and the exit code too, and plays a different sound depending on whether the command was successful or not. This allows for some neat integrations with KDE connect to let me know when some long compile has finished or something even when I’m away from my computer. You can see how it works here.
