Notification not in notification center

[Vartkat]

I tried with or without -timeout or -group, setting alerter as banner or notifications, telling System Pref to keep 20 notifications from alerter, nothing works, notifications are disappearing from notification center as soon as they're added (I'm in 10.11 El Capitan).

Is that a normal behavior ?

I can't get anything to work either. Simple stuff like ./alerter ‐message 'test' merely prints usage as:

${EXECUTABLE_NAME} (1.0.0) is a command-line tool to send OS X User Notifications.
...

and while more complicated parameters seems to run, nothing is displayed on screen and alerter must be manually quit. Also on El Capitan.
