I'm writing a PowerShell script that will execute commands on a remote host using Invoke-Command and its -ScriptBlock
parameter. For example,
function Foo {
...
return "foo"
}
$rv = Invoke-Command --Credential $c --ComputerName $fqdn -ScriptBlock ${function:Foo}
This works fine. What I'd like to do now is the same thing, but call a function with local arguments. For example,
function Bar {
param( [String] $a, [Int] $b )
...
return "foo"
}
[String] $x = "abc"
[Int] $y = 123
$rv = Invoke-Command --Credential $c --ComputerName $fqdn -ScriptBlock ${function:Foo($x,$y)}
But this does not work:
Invoke-Command : Cannot validate argument on parameter 'ScriptBlock'.
The argument is null. Supply a non-null argument and try the command
again.
How can I use Invoke-Command with a -ScriptBlock
that is a local function with arguments?
I realize that I can wrap the entire function and the parameters in a big code block, but that is not a clean way of doing it, in my opinion.
