PowerShell: Function to Execute Function Remotely

Function this function that – this quick snippet is to invoke those func things remotely…

More complex version:

$computerNames=$env:computerName,"localhost"

function pingSomething{
    param($names)
    $result=$names|%{ping $_}
    return $result;
}

# Limitation: this function currently only takes one function with multiple parameters (that are not nested functions)
function execFunctionAsJob{
    param($computername,$functionName,$parameters)
    #$scriptBlock=${function:$functionName} # another method to retrieve the inside codes of a provided function
    $scriptBlock=(Get-Command $functionName -CommandType Function).Definition;
   
    <# Alternative method
    $session=new-pssession -ComputerName $computername
    $job=invoke-command -Session $session -ScriptBlock{
    param ($importedFunction,$params)
        return [ScriptBlock]::Create($importedFunction).invoke($params);
    } -args $scriptBlock,$parameters
    Remove-PSSession $session
    #>
    $job=invoke-command -ComputerName $computername -ScriptBlock{
        param ($importedFunction,$params)
            return [ScriptBlock]::Create($importedFunction).invoke($params);
        } -args $scriptblock,$parameters -AsJob
    return $job
}

function simultaneousExec{
    param($computerNames,$functionName,$parameters)
    $timer=[System.Diagnostics.Stopwatch]::StartNew();
    $jobIds=@()
    foreach ($computer in $computerNames){
        $job=execFunctionAsJob -computername $computer -functionName $functionName -parameters $parameters
        #$job=execFunctionAsJob -computername $computer -functionName "pingSomething" -parameters "yahoo.com","google.com"
        $jobIds+=,$job.Id
        }
    Wait-Job -Id $jobIds;
    $jobResults=Receive-Job -Id $jobIds;
    Remove-Job -id $jobIds;
    $time=[math]::round($timer.Elapsed.TotalHours,2);
    $timer.Stop();
    $timer.Reset();
    $closingMessage="`r`nOverall Time: $time hours"
    write-host $closingMessage;

    return $jobResults
}

simultaneousExec -computerNames $computerNames -functionName "pingSomething" -parameters "kimconnect.com","google.com","yahoo.com"

Simple version:

function pingSomething{
    param($name)
    return ping $name;
}

function execFunctionRemotely{
    param($computername,$functionName,$parameters)
    #$scriptBlock=${function:$functionName} # another method to retrieve the inside codes of a provided function
    $scriptBlock=(Get-Command $functionName -CommandType Function).Definition;    
    $session=new-pssession -ComputerName $computername
    $result=invoke-command -Session $session -ScriptBlock{
    param ($importedFunction,$params)
        return [ScriptBlock]::Create($importedFunction).invoke($params);
    } -args $scriptBlock,$parameters
    Remove-PSSession $session
    <# Alternative method
    $result=invoke-command -ComputerName $computername -ScriptBlock{
        param ($importedFunction,$params)
            return [ScriptBlock]::Create($importedFunction).invoke($params);
        } -args $scriptblock,$parameters
    #>
    return $result
}
execFunctionRemotely -computername $env:computername -functionName "pingSomething" -parameters "google.com"
