Powershell 需要帮助读取文本文件并输出到csv吗

下面是从几个系统的注册表中获取信息的一种方法。因为我没有任何McAfee软件，所以我使用Python作为占位符。代码注释似乎足够了，但请随时要求澄清。[咧嘴笑]

$Results中的第一项

#requires -RunAsAdministrator

# fake reading in a list of systems
#    in real life, use Get-Content
$SystemList = @'
LocalHost
10.0.0.1
127.0.0.1
BetterNotBeThere
'@ -split [System.Environment]::NewLine

$sb = {
    $RegPath = 'HKLM:\SOFTWARE\Python\PythonCore\3.8'
    Get-ChildItem -LiteralPath  $RegPath -Recurse |
        ForEach-Object {
            Get-ItemProperty $_.pspath
            }
    }

# the "-ErrorAction SilentlyContinue" will make PoSh NOT show error on the screen
#    if you need to get a list of non-responders, you can compare the input list to the items in "$Results"
$Results = Invoke-Command -ScriptBlock $sb -ComputerName $SystemList -ErrorAction SilentlyContinue

$Results |
    # filter out the items with no path info or lots of extra properties
    Where-Object {
        $_.'(default)'
        } |
    # remove unwanted properties & add a ComputerName prop
    Select-Object -Property @{n = 'ComputerName'; e = {$_.PSComputerName}}, * -ExcludeProperty 'RunspaceId', 'PSShowComputerName' |
    Export-Csv -LiteralPath "$env:TEMP\powershelltek_HKLM-Software-Info.csv" -NoTypeInformation

感谢Prasoon，我正在尝试从文本文件读取主机，然后将它们输出到csv文件，到目前为止，在-ComputerName

Invoke命令

接受

-ComputerName

参数中的系统列表后，我一次只能输入一个主机。[咧嘴笑]嗨，李，我是新来的powershell如果你能提供语法的话，我没有任何McAffe的东西，所以我很好奇你在那个地方寻找什么。对我来说，

Python

的类似位置包含

（默认值）：C:\Python38\Lib\idlelib\idle.pyw

以及powershell添加的一系列内容[通常前缀为

PS

]。那么，您想从这些项目中向您的CSV添加什么？请发布您获得的详细信息-将它们添加到您的原始帖子-以便我可以使CSV有意义。否则，我将不得不使用系统中的某些内容作为占位符。在$SystemList=@'中，您能否澄清用法？

$SystemList

部分只是提供系统名称示例集的一种方法。代码的工作方式应与系统上的工作方式完全相同。正如注释所暗示的[

在现实生活中，使用Get Content

]，当您准备好使用真实的系统名称时，使用

Get Content

，

Import CSV

加载它们，或者通过类似于

Get-ADComputer

的方式。Hi-Lee脚本运行良好，但当我使用Get-Content-Path获取主机列表时，它将出错：Invoke命令：无法验证参数“ComputerName”上的参数。参数为null或为空。请提供一个不为null或为空的参数empty@powershelltek-这意味着您在加载文件时遇到问题。[grin]此时，

$SystemList

中是否有任何内容？另外，您是如何替换该代码段的？最简单的方法是在整个块之后添加一行

$SystemList=Get Content

，然后删除或注释掉以

@-split[System.Environment]：：NewLine

结尾的块。一旦有了自己的测试[或真实]数据，就不需要整个here字符串。Lee脚本现在运行时没有错误。添加Get内容后，将创建csv文件，但其中没有数据
