Hello Experts,

How would I capture the output of running a remote command locally on my machine. I need to capture the output to a file locally on my machine. The output should be Computername, result. (There should be only 1 folder.)

$computers = gc c:\computers.txt
foreach ($computer in $computers) {
Invoke-Command -Computername  $computer - ScriptBlock { Get-ChildItem "c:\appoutput"}
}
Thanks for your assistance,

The output should be Computername, result.
I have no idea what "result" should be.  And what do you mean by capture?  Save to a file?  Multiple files?  Gathering all results together into an array and saving to a variable?

In general I'd recommend something like this.
gc c:\computers.txt | foreach `
{
    Invoke-Command -Computername  $_ -ScriptBlock { Get-ChildItem "c:\appoutput" }
}

Open in new window


or make use of fan-out remoting (running on multiple remote machines at once)
$computers = gc c:\computers.txt
Invoke-Command -Computername  $computers -ScriptBlock { Get-ChildItem "c:\appoutput" }

Open in new window


When you run a command against a remote machine like above, the returned object has a "PsComputerName" property with the value being the name of the computer it was returned from.

You could pipe either of the above commands to a Select statement to choose specific properties and output to a file.  If you wanted to save to a variable you could just preface the Invoke-Command line with "$variable = ".

If I want to do something for each machine within the script block { if exist c:\appout\123.bin $existentry = "yes", output to local file $computer, $existentry }
