Create a cmd prompt for a URL then set that URL as $URL in a powershell script

Question

Using a series of scripts to build a signage PC that opens Chrome and displays a specific URL. I have been manually setting the URL withing the powershell script that opens Chrome and displays the page. Since a batch is used to do some setting up of the unit, I'd like to set the $URL variable in the PS1 via a prompt during the setup bat.

I have tried a few things from other threads with no luck. I have little experience with batch or powershell. Not a task I was given but figured it may be nice to improve what I have been given as the current standard procedure.

Thanks in advance.

In my experience, the best way to transfer info from Batch to PowerShell is to use environment variables.

For example, if you have a PowerShell script named MyPowerShellScript.ps1, having the following content:

$URL = $Env:URL
Write-Host "[URL=$URL]"

And call it with the following batch file:

@ECHO OFF
REM As per mklement0's comment, SETLOCAL limits environment changes to batch file
SETLOCAL
SET "URL=https://stackoverflow.com/"
PowerShell -NoProfile -ExecutionPolicy Bypass -file MyPowerShellScript.ps1

Will give this output:

[URL=https://stackoverflow.com/]

setlocal is need for .cmd files too (just tried it), so I don't think the extension matters here. You definitely want this to be an explicit feature, otherwise you wouldn't be able to set process-level environment variables.
