How can I Start-Process powershell.exe with some string splitter?

问题

I want to start powershell.exe with a scriptblock like this (it's working fine):

Start-Process powershell.exe {
  Get-Help 
  Get-Process
}

But this script doesn't work:

Start-Process powershell.exe {
  $string = "123xAbcxEFG"
  $split1,$split2,$split3 = $string.Split("x")
  Write-Output $split1
  Write-Output $split2
  Write-Output $split3
  sleep 10
}

I think I need Add-Type -AssemblyName "SomeNameSpace", but how can I find that namespace? Any intellisense or something like this?

回答1:

you can use start-job it's actually start new powershell process . and you can do is easy. like this :

start-job

for more help use :

get-help start-job

The problem is with the quotes. It works, if you e.g. put additional single quotes around your double quotes. It also works with triple double quotes.

Start-Process powershell.exe  {
$string = """123xAbcxEFG"""
$split1,$split2,$split3 = $string.split("""x""")
Write-Output $split1
Write-Output $split2
Write-Output $split3
sleep 10
}

How I changed your code to catch the error (without the additional double quotes):

$ScriptBlock = {
  $string = "123xAbcxEFG"
  $split1,$split2,$split3 = $string.split("x")
  Write-Output $split1
  Write-Output $split2
  Write-Output $split3
  sleep 10
}

Start-Process powershell -argumentlist "-noexit -command $ScriptBlock"
