Find exit code for executing a cmd command through PowerShell

Question

I am using a silent installation command to install software. I am running this command from PowerShell 3.0.

$silentInstall = C:\\Users\\Admin\\Documents\\Se         


        

Answer 1

It depends on how the EXE file runs - sometimes it will kick off a separate process and return immediately, and in such cases this usually works -

$p = Start-Process -FilePath  -ArgumentList  -Wait -NoNewWindow -PassThru
$p.ExitCode

Otherwise this usually works -

&  
$LASTEXITCODE

Or sometimes this -

& cmd.exe /c  
$LASTEXITCODE
