Getting Powershell return code within a .BAT program

Question

I have a .BAT program where I'm calling a Powershell script to run.

How I can get the exit code in the .BAT program when the powershell finishes its work?

EDIT:

This has worked for me.

call powershell.exe .\MyPowerShellScript.ps1
echo %ERRORLEVEL%

Answer 1

The %ERRORLEVEL% variable will give you the last return code:

@echo off

call powershell.exe -Command "exit 123"
echo Exited with return code %ERRORLEVEL%

Will result in:

C:\> path\to\script.bat
Exited with return code 123

With a script, either use the -File parameter:

@echo off

call powershell.exe -File "path\to\file.ps1"
echo Exited with return code %ERRORLEVEL%

or use the & call operator to invoke the script:

@echo off

call powershell.exe -Command "& 'C:\path\to\file.ps1'"
echo Exited with return code %ERRORLEVEL%
