Use Powershell variable in Batch

Question

@echo off
Powershell.exe -executionpolicy remotesigned -File C:\Users\aborgetti\Desktop\getdate.ps1

FOR /F "usebackq delims=" %%v IN ('powershell -noprofile -File C:\Users\aborgetti\Desktop\getdate.ps1') DO set "d=%%v"

echo %d%

This is the part that I am confused about...not really sure how to set the variable from powershell to a variable in the .bat file.

 FOR /F "usebackq delims=" %%v IN ('powershell -noprofile -File C:\Users\aborgetti\Desktop\getdate.ps1') DO set "d=%%v"

Any help would be much appreciated.

BTW

The $d variable is being used in a set of initial commands for an FTP program called Bluezone FTP 3.2

getdate.ps1 looks like this:

$a = Get-Date
$b = $a.ToString('MMddyy')
write-host $b

Answer 1

Your powershell script needs to output the value, not store it in a variable. Two different solutions(untested), inspired by @zdan's answer in a differen SO question:

FOR /F "usebackq delims=" %%v IN (`powershell -noprofile "& { (get-date).ToString('MMddyy') }"`) DO set "d=%%v"

Or:

getdate.ps1:

$a = Get-Date
$b = $a.ToString('MMddyy')
$b

Batch:

FOR /F "usebackq delims=" %%v IN (`powershell -noprofile -File "C:\Users\ab\Desktop\getdate.ps1"`) DO set "d=%%v"
