Без сомнения, «параметр» versionлегче всего объяснить. :)

@jimmij Не могли бы вы сделать это так? :-) Какой пакет?

пакет libnotify. Просто беги notify-send -v. -vили --versionэто очень стандартная опция в мире Linux, чтобы попросить программу напечатать свой внутренний номер версии. Попробуйте например ls --version.

Спасибо @jimmij, я подумал, что это еще один параметр, который я должен указать при вызове команды (например, версия скрипта, которая ее вызывает, или что-то в этом роде).
