how to use powershell to exec the command and get result

I want to user powershell to exec the command and get the execute result

let's say i want to use msival2.exe to certificate the msi installation package, and the exe will give me the information DURING the certification process..

I use Invoke-Expression and like that...

$out_put = Invoke-Expression ".\msival2.exe $msiPackageName darice.cub"

I could get the result from $out_put, ONLY AFTER the certification....

How could I get the result DURING the process of command just like I run the msival2.exe manually...

Thanks

Solution

  • If you want to collect the output from msival2.exe and at the same time see the output on the screen as it appears, I would suggest using the call operator &, and use Tee-Object to copy the output to a variable:

    & .\msival2.exe $msiPackageName darice.cub |Tee-Object -Variable out_path
