The command "zenity --question" is used to create a graphical dialog box prompting the user with a yes or no question. The "zenity" command is a utility for displaying graphical dialog boxes in Linux and Unix-based systems.

In this case, "--question" is an option that specifies to create a dialog box with a question along with Yes and No buttons. When the dialog box is displayed, the command will wait for the user to click either the Yes or No button. Once a button is clicked, the command will exit and return an appropriate exit code indicating the user's choice (0 for Yes, 1 for No). This allows scripts to include decision-making logic based on the user's response.

For example, you can use this command in a script to ask the user if they want to proceed with a specific operation. If the user clicks Yes, the script can continue executing the subsequent commands. If the user clicks No, the script can exit or take alternative actions based on the response.
