You can use hybrid bat with powershell, and with some searching on the examples available on the internet.

You can quickly adapt it so that it best suits your goal, a lot and take advantage of the resulting learning and consider migrating to powershell.

Below is an example using a script I made a few months ago to get a folder listing by multiple selection/click and which I adapted by adding output to following actions by the user:

• Selected items
• Unselected item
• Cancel click/close
• Timeout 10 seconds // if no actions

• Start-CountDownTimer.ps1
• Multiple selection list boxes
• Cancel button in a powershell script
• An A-Z Index of Windows PowerShell commands
• How to add a timer in ps1 to quit the form after certain amount of time

Although there might be no "direct way", there are several work arounds e.g. doing a time out of the main script while a second script is doing the user query. The second script can for example write it's result into a file (or not, if it is ignored). After the time out the first script continues with evaluating the result (or cancelling the second script if it was ignored).

That all depends on the type of command terminal you want to use for the batch file e.g. powershell, cmd, or some other. Here are a few examples:

• Here is how to add a time out in cmd

• Here is how to add a time out in a powershell
