libnotify notify-send

Không có nghi ngờ "tham số" versionlà dễ giải thích nhất. :)

— jimmij

@jimmij Bạn có tử tế khi làm vậy không? :-) Gói gì?

— Ivan

gói libnotify. Cứ chạy đi notify-send -v. -vhoặc --versionlà tùy chọn rất chuẩn trong thế giới Linux để yêu cầu chương trình in số phiên bản nội bộ của nó. Hãy thử ví dụ ls --version.

— jimmij

Cảm ơn @jimmij, tôi nghĩ đó là một tham số khác mà tôi phải chỉ định khi tôi gọi lệnh (giống như một phiên bản của tập lệnh đang gọi nó hoặc một cái gì đó tương tự).
