回答:
アプリケーションウィンドウのタイトルを使用して、ターミナルからそれぞれのアプリケーションを開く正しいコマンドを見つける次のスクリプトを作成しました(名前はappcmd):
#!/bin/bash
#appcmd - script which use the application window title to find out the right command which opens the respective application from terminal

このスクリプトを~/binディレクトリに保存し、実行可能にすることを忘れないでください:
chmod +x ~/bin/appcmd
使用法:
引数なしでスクリプトを実行すると、スクリプトは対応する開かれたすべてのウィンドウのすべてのコマンドを返します。
引数が指定されている場合、スクリプトは、その引数をタイトルに含む開いているアプリケーションウィンドウを見つけようとし、対応するコマンドを返します。たとえば、Chromiumブラウザが開いている場合、次のコマンドのみを使用して端末から開くコマンドを見つけることができます。
appcmd chromium
leafpad、次のようなテキストエディタを起動しますleafpad --tab-width=2。出力には次のものが含まれ--tab-width=2ますか?
leafpad現在インストールしていませんが、一部のアプリケーションでは、はい、引数も返します。
ここから:
xprop | awk '($1=="_NET_WM_PID(CARDINAL)") {print $3}' | xargs ps h -o pid,cmd
開始コマンドラインのみが必要な場合:
xprop | awk '($1=="_NET_WM_PID(CARDINAL)") {print $3}' | xargs ps h -o cmd
コマンドを実行した後、開始コマンドを表示するウィンドウをクリックするだけです。

使用法:

スクリプトを必要としない別の方法として、システムモニターを開いて、コマンドラインを知りたいプロセスにマウスを合わせることができます。
「依存関係ビュー」を有効にすると、別のプロセスを呼び出すことができます。たとえば、Chromeが各タブに対して作成するさまざまなプロセスを確認し、コマンドラインを持つ親プロセスまでトレースできます。どのChromeが(ユーザーによって)呼び出されたか。
