Starting PowerShell with Start-Process RRS feed

  • Question

  • Hi,

    I'm trying to start PowerShell using Start-Process. Task looks simple for sure.

    Start-Process -FilePath C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -ArgumentList "-NoExit","-command `"& { get-date } "

    I can handle variables also,

    Start-Process -FilePath C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -ArgumentList "-NoExit","-command `"& { `$date = get-date; `$date } "

    Main problem is that I would like to have "here" strings inside script block.

    $str = @"



    But I was not able to find how to do this.

    Any help is appreciated.

  • Why?  Just use a file:

    Start-Process powershell.exe -ArgumentList '-NoExit -File .\myscript.s1'

  • In my case file is not a option, but I got hint (thanks to Aleksandar Nikolic) to use encrypted command and it worked like charm.

    $command = @'



    $bytes = [System.Text.Encoding]::Unicode.GetBytes($command)
    $encodedCommand = [Convert]::ToBase64String($bytes)
    $arg = "-NoExit", "-encodedCommand $encodedCommand"

    Start-Process -FilePath C:\Windows\system32\WindowsPowerShell\v1.0\powershell.exe -ArgumentList $arg

  • Remember that the command line has a length limitation.
