Powershell - 从文件中导入数据

Question

我是 Powershell 新手，但遇到了问题。我在下面有这段代码，执行后它会提示在 AD 中输入组名，然后将该组的所有成员导出到 .csv 文件中。如何更改此项以从 .csv 文件导入多个组名？

param
(   
    [Parameter(Mandatory=$true,position=0)]
    [String]$GroupName
)

$GFile = New-Item -type file -force "C:\Scripts\GroupDetails.csv"

$Groups = Get-ADGroup -filter {Name -like $GroupName} | Select-Object Name

ForEach ($Group in $Groups) {

    Get-ADGroupMember -identity $($group.name) -recursive | Select-Object samaccountname | Out-File $GFile -append
}

也许这样的事情会帮助你：

Param (
    [ValidateScript({Test-Path -Path $_ -PathType Leaf})]
    [String]$ImportFile = 'S:\Test\Input_Test\GroupNames.txt',
    [ValidateScript({Test-Path -Path $_ -PathType Container})]
    [String]$SaveFolder = 'S:\Test\Input_Test'
)

$Groups = Get-Content $ImportFile

ForEach ($Group in $Groups) {
    Get-ADGroupMember -Identity $Group -Recursive | 
        Select-Object -ExpandProperty SamAccountName | 
            Out-File -LiteralPath (Join-Path $SaveFolder "$Group.txt")
}

你可以用你想要的组填充文件GroupNames.txt，它会为每个组创建一个文件。

内容 GroupNames.txt：

Group 1
Group 2

如果你想更高级一点，你可以创建一个这样的函数：

Function Export-ADGroupMembersToFile {
    Param (
        [Parameter(Mandatory)]
        [ValidateScript({Test-Path -Path $_ -PathType Leaf})]
        [String]$ImportFile,
        [Parameter(Mandatory)]
        [ValidateScript({Test-Path -Path $_ -PathType Container})]
        [String]$SaveFolder
    )

    $Groups = Get-Content $ImportFile

    $OutFile = Join-Path $SaveFolder "Groups_$(Get-Date -F 'yyyyMMddHHmm').txt"
    Write-Verbose  "Output will be saved to file '$OutFile'"

    ForEach ($Group in $Groups) {
        Write-Verbose "GroupName: $Group"
        "`n", $Group, ('-'*40) | Out-File -LiteralPath $OutFile -Append

        $Members = Get-ADGroupMember -Identity $Group -Recursive | 
            Select-Object -ExpandProperty SamAccountName

        foreach ($M in $Members) {
            Write-Verbose "Adding user $M"
            Out-File -InputObject $M -LiteralPath $OutFile -Append
        } 
    }
}

Export-ADGroupMembersToFile -ImportFile 'S:\Test\Input_Test\GroupNames.txt' -SaveFolder 'S:\Test\Input_Test' -Verbose

这将输出一个包含所有 GroupNames 的文件。
