限制同时运行的线程数

Question

我有一个脚本可以对我的工作环境进行ping扫描，并且我试图限制同时运行的线程数。我一直在网上尝试许多解决方案，但似乎无法取得任何进展。任何帮助将不胜感激。

$scriptblock = {

Param($comp)
IF (Test-Connection -computername $comp -Quiet -Count 1) {
    [bool]$responding = $true
}
else {
    Write-Host "***$comp ERROR -Not responding***" 
    $responding = $false
}

New-Object psobject -Property @{'Computer Name' = $comp;
    'Online'                        = $responding;

}  

}

$CurrentDate = Get-Date
$CurrentDate = $CurrentDate.ToString('MM-dd-yyyy_hh-mm-ss')
$location = Get-Location

$comps = (get-content -path $location'\hostnames.txt').Trim()
$comps | ForEach-Object {Start-Job -Scriptblock $scriptblock -ArgumentList  $_ | Out-Null}

Get-Job | Wait-Job | Receive-Job | Select-Object 'Computer Name','Online'`
-ExcludeProperty RunspaceId, PSComputerName, PSShowComputerName   |   Export-csv -NoTypeInformation "$location\PingTest-$CurrentDate.csv"
