我有一个PowerShell脚本，该脚本从Windows Server获取所有用户和组数据。但是该脚本必须在每台服务器上运行，因为我找不到在不同服务器上运行的-ComputerName选项。因此必须修改该脚本，并且当我们基于服务器列表输入从一台服务器运行该脚本时，它应该从Windows服务器获取所有数据。
答案 0 :(得分：0)
如果您有一个脚本甚至可以在一台计算机上执行此操作，则可以使用ForEach在任意数量的计算机上执行该脚本。
'computer1',computer2','computer3' |
ForEach {
# put your code here
# and for the computername property, use $PSItem to get the name being passed in
}
您只需使用环境变量
即可获取运行代码的当前计算机名称。$env:COMPUTERNAME
或仅使用
hostname
您没有在做的就是向我们显示您的代码，因此我们不知道您在做什么。 许多cmdlet / WMI和CIM类都有计算机名称参数，因此，如果看不到该参数，则说明您没有使用具有此功能的cmdlet /功能。
这还表明您对PowerShell还是非常陌生的，我建议您花些时间来加速。使用YouTube，MSDN Channe9或MS了解资源并搜索...
始终首先使用帮助文件。
