間違いなく「パラメータ」versionが最も簡単に説明できます。:)

@jimmijその時とても親切になりますか？:-)パッケージは何ですか？

パッケージlibnotify。実行するだけnotify-send -vです。-vまたは--version、Linuxの世界で非常に標準的なオプションであり、プログラムに内部バージョン番号を出力するように依頼します。たとえば、試してみてくださいls --version。

@jimmijに感謝します。これは、コマンドを呼び出すときに指定することになっている別のパラメーターだと思いました（呼び出しているスクリプトのバージョンなど）。

manpage（DebianのGNU / Linuxの中では）を見てお勧めhttp://www.galago-project.org/specs/notification/。

   | "desktop-entry"> | string     | application's .desktop file. An        |
   |                  |            | example would be "rhythmbox" from      |
   |                  |            | "rhythmbox.desktop". This can be used  |
   |                  |            | by the daemon to retrieve the correct  |
   |                  |            | icon for the application, for logging  |

   |                  |            | We use this value if the icon field is |

   |                  |            | playing any sounds, if it has that     |
   | "suppress-sound" | boolean    | ability. This is usually set when the  |

   |                  |            | sound.                                 |
