Invoke-Command

[kort3x]

I have a Question: How do I pass a variable to invoke-command inside the ScriptBlock of Start-RSJob. Following is not working:

$JobsInvoke = $PSsessions | Start-RSJob -ScriptBlock { $ip = "8.8.8.8"; Invoke-Command -Session $_ -ScriptBlock {test-connection -ComputerName $using:ip }}

It fails with

Start-RSJob : The value of the using variable '$using:ip' cannot be retrieved because it has not been set in the local session.

You can use parameters and -ArgumentList for Invoke-Command something like that

$JobsInvoke = $PSsessions | Start-RSJob -ScriptBlock { $ip = "8.8.8.8"; Invoke-Command -Session $_ -ScriptBlock {param($ip) test-connection -ComputerName $ip } -ArgumentList $ip }

@proxb , may be there is room for #118's -VariableToLoad ? with rule "if -VariableToLoad used then $using:variable not expanded"

Ok, I tried

$JobsInvoke = $PSsessions | Start-RSJob -ScriptBlock { $ip = "8.8.8.8"; Invoke-Command -Session $_ -ScriptBlock {param($ip) test-connection -ComputerName $ip } -ArgumentList $ip }

but now $_ appears to be empty, as I receive "Argument is NULL or empty" for the -session paramter of Invoke-Command.

I dont get it...

btw, when I try an Invoke-Command without an ArgumentList like a simple Get-Date, there is no problem with -session.

$JobsInvoke = $PSsessions | Start-RSJob -ScriptBlock { $ip = "8.8.8.8"; Invoke-Command -Session $_ -ScriptBlock {get-date } }

seems there is a bug in current version, #144, #145 with $args[0] instead of $_ my example works ok

That sounds like a good idea to look at implementing.
