从多台计算机获取WMI数据并导出到CSV [英] Get WMI Data From Multiple Computers and Export to CSV

问题描述

因此，今天拥有一些不错的老式Powershell挫败感.我需要做的是这样:

So having some good old fashion Powershell frustrations today. What I need to do is this:

1. 从文件获取计算机列表
2. 从Win32_OperatingSystem查询那些计算机的"CSName"和"InstallDate"
3. 将InstallDate转换为可用的日期格式.
4. 将所有内容导出到.csv

我已经尝试了许多不同的脚本迭代.我遇到了两个主要问题.一是即使使用Export-Csv -Append，我也无法导出并附加到.Csv.它仅采用第一个值，其余则不执行任何操作.第二点是，在管道|时，我无法使datetime转换器正常工作.

I've tried so many different iterations of my script. I run into 2 major issues. One is that I can't export and append to .Csv even with Export-Csv -Append. It just takes the first value and does nothing with the rest. The 2nd is that I can't get the datetime converter to work when piping |.

以下是我尝试过的一些示例-均无用.

Here's a few samples of what I've tried - none of which work.

此示例仅犯了很多错误.似乎没有从管道中的WMI查询中继承$_.看起来它正在尝试使用第一个管道中的数据，但我不确定.

This sample simply errors a lot. Doesn't seem to carry $_ over from the WMI query in the pipe. It looks like it is trying to use data from the first pipe, but I'm not sure.

    Get-Content -Path .\Computernames.txt | Foreach-Object {
        gwmi Win32_OperatingSystem -ComputerName $_) |
            Select-Object $_.CSName, $_.ConvertToDateTime($OS.InstallDate).ToShortDateString()
    } | Export-Csv -Path Filename -Force -Append -NoTypeInformation
}

这个简单地导出第一个值，而在导出.Csv时放弃其余的值

This one simply exports the first value and gives up on the rest when exporting .Csv

$Computers = Get-Content -Path .\Computernames.txt
foreach ($Computer in $Computers) {
  echo $Computer
  $OS = gwmi Win32_OperatingSystem -ComputerName $Computer
  $OS | Select-Object
  $OS.CSName,$OS.ConvertToDateTime($OS.InstallDate).ToShortDateString() |
      Export-Csv -Path $Log.FullName -Append
}

这个确实可以获取数据，但是当我尝试选择任何内容时，我会得到空值，但是我可以echo很好.

This one does get the data, but when I try to select anything, I get null values, but I can echo just fine.

$OS = gwmi Win32_OperatingSystem -ComputerName $Computers
$OS | Foreach-Object {
    Select-Object $_.CSName,$_.ConvertToDateTime($OS.InstallDate).ToShortDateString() |
        Export-Csv -Path $Log.FullName -Force -Append -NoTypeInformation
}

这感觉应该很简单.我几乎可以毫不费力地用C#做到这一点，但是我无法让PS来完成我想要的事情.任何帮助将不胜感激！

This feels like it should be ridiculously simple. I can do this in C# with almost no effort, but I just can't get PS to do what I want. Any help would be much appreciated!

推荐答案

来了，

$Array = @() ## Create Array to hold the Data
$Computers = Get-Content -Path .\Computernames.txt

foreach ($Computer in $Computers)
{
    $Result = "" | Select CSName,InstallDate ## Create Object to hold the data
    $OS = Get-WmiObject Win32_OperatingSystem -ComputerName $Computer

    $Result.CSName = $OS.CSName ## Add CSName to line1
    $Result.InstallDate = $OS.ConvertToDateTime($OS.InstallDate).ToShortDateString() ## Add InstallDate to line2
    $Array += $Result ## Add the data to the array
}

$Array = Export-Csv c:\file.csv -NoTypeInformation
