powershell pass command line arguments

Question

Here is my code :

$script={
 Write-Host "Num Args:" $args.Length;
  Write-Host $args[0]   
}

Invoke-Command  -ScriptBlock $script

When I run

  powershell.exe .\test.ps1 one two three

I got

Num Args: 0

I thought I would get

Num Args: 3
One

Something am I missing?

Thanks

Answer 1

You actually have two scopes there. The script level and the script block level. $args.Length and $args[0] will have what you are expecting at the Invoke-Command level. Inside the script block there is another scope for $args. To get the args from the command line all the way into the script block you'll need to re-pass them from Invoke-Command -ArgumentList $args.

Answer 2

You need to pass the arguments to the scriptblock:

Invoke-Command  -ScriptBlock $script -ArgumentList $args
