Sure. I found this question on Ask Ubuntu https://askubuntu.com/questions/409611/desktop-notification-when-long-running-commands-complete https://askubuntu.com/questions/409611/desktop-notification-... and the second response mentions the alert alias. I'm not sure if this alias is found only in Ubuntu and derivatives (I'm using Linux Mint) or if it's standard among all Linux distributions. Simply add ; alert after your commands to receive the notification.
