Multithreading 如何使用多线程脚本
我在上找到了这个多线程脚本 但我不知道如何使用它。特别是如何使用$ObjectList变量。我想用我写的这个ping脚本ping一个100000台机器的列表。。。但以目前的形式，它每分钟发出大约100台机器的声音。因此，完成这项工作需要16个多小时Multithreading 如何使用多线程脚本,multithreading,powershell,Multithreading,Powershell,我在上找到了这个多线程脚本 但我不知道如何使用它。特别是如何使用$ObjectList变量。我想用我写的这个ping脚本ping一个100000台机器的列表。。。但以目前的形式，它每分钟发出大约100台机器的声音。因此，完成这项工作需要16个多小时 $Computers = Get-Content -Path C:\Temp\Comps.txt foreach ($Computer in $Computers) { if (test-Connection -ComputerName
$Computers = Get-Content -Path C:\Temp\Comps.txt
foreach ($Computer in $Computers) {
if (test-Connection -ComputerName $Computer -Count 1) {
"$Computer is Pinging"
}
Else {
"$Computer is not Pinging"
}
}
我假设我将从ping脚本中删除$Computers变量，而在多线程脚本中使用$ObjectList变量。但是我所有的尝试都失败了。您可以使用[System.Net.NetworkInformation.ping]异步ping主机，无需使用运行空间。此外，它将ping主机一次，因此比测试连接快得多。下面是一批主机（约90台）的示例。我想一次装载100K不是一个好主意，可能会将其分成更小的批次，然后逐个装载

这个脚本，我从大纲中的链接和作者那里改编，对我来说有很好的表现。我对它进行了修改，不仅采用了一系列ip地址，还采用了一系列主机名。正因为如此，一些变量名的名称很糟糕，但这不是生产代码，所以我没有在下面的内容之外对其进行投资
function Global:Ping-IPRange {
<#
.SYNOPSIS
Sends ICMP echo request packets to a range of IPv4 addresses between two given addresses.
.DESCRIPTION
This function lets you sends ICMP echo request packets ("pings") to
a range of IPv4 addresses using an asynchronous method.
Therefore this technique is very fast but comes with a warning.
Ping sweeping a large subnet or network with many swithes may result in
a peak of broadcast traffic.
Use the -Interval parameter to adjust the time between each ping request.
For example, an interval of 60 milliseconds is suitable for wireless networks.
The RawOutput parameter switches the output to an unformated
[System.Net.NetworkInformation.PingReply[]].
.INPUTS
None
You cannot pipe input to this funcion.
.OUTPUTS
The function only returns output from successful pings.
Type: System.Net.NetworkInformation.PingReply
The RawOutput parameter switches the output to an unformated
[System.Net.NetworkInformation.PingReply[]].

In this example all the ip addresses between 192.168.1.1 and 192.168.1.254 are pinged using
a 20 millisecond interval between each request.
All the addresses that reply the ping request are listed.
