Notification after command execution

To notify only if the command execution succeeds, use &&.

command && notify-send

To notify after a command (or shell-script, or background job) is completed, without worrying whether the commands succeeded or failed use ;.

long job ; notify-send

This method is extremely helpful when you are executing a long running shell-script in the background and you would like to be notified with a little nice non-intrusive pop-up when the job is completed.

Urgency level

You can specify an urgency level with -u or --urgency=LEVEL. Levels can be used: - low - normal - critical

Expire time

Set the timeout in milliseconds at which to expire the notification using -t or --expire-time=TIME
