LASTEXITCODE in powershell is alway 0

Question

I am not a great powershell expert and I stumble on a problem that is undoubtedly trivial

When I run the following command in CMD (SAP related but it's not important)

.\sapcontrol.exe -nr 00 -prot PIPE -function GetProcessList

I get an exit code which may have different values depending on the state of the processes :

• 0 Last webmethod call successful

• 1 Last webmethod call failed, invalid parameter

• 2 StartWait, StopWait, WaitforStarted, WaitforStopped, RestartServiceWait timed out

• 3 GetProcessList succeeded, all processes running correctly

• 4 GetProcessList succeeded, all processes stopped

In powershell when i use

Start-Process or & cmd.exe / c my $LASTEXITCODE or $? always returns 0 (probably to tell me that the command has been executed ... but that's not what I want ...)

how to get the equivalent of EXITCODES in powershell ?

thanks in advance

Answer 1

With Start-Process you can pass the argument -PassThru to get an object containing the process. Then, you can use the exit code property inside that object using $YourProcess.ExitCode :

$oProcess = Start-Process -Path $executablePath -ArgumentList $executableArguments -Wait -PassThru
$exitcode = $oProcess.ExitCode
