How to - clear - notifications from command-line?

[Yummi]

Just simple question: is there a way to clear the list notifications with command-line script?

With 'pineapple notify [text]' we can add but how to clear all old notifications in an automated way?

( Further: it should be nice if the Search-box in Forums will remember one's last given string or strings. )

Kind regards,

Yummi
