使用Powershell取出属于某些指定组的用户并导出为csv

知识这东西就像雪球，越滚越大，今天看到了这篇自己1年多前写的博文，简直弱爆了。于是更新一下程序：

2016-6-15更新，短短几行代码，就拿到了组和组成员，其中还用到了递归，以处理组成员是组的情况：

Get-ADGroup -Filter * -SearchBase "ou=test-ou,ou=vb-group,dc=corp,dc=vb" | foreach {
    [PSCustomObject]@{'GroupName'=$_.name;'Members'=$null}
    Get-ADGroupMember -Identity $_.name -Recursive | foreach {
        [PSCustomObject]@{'GroupName'=$null;'Members'=$_.name}
    }
}

以下是一年多前写的：

cd 'F:\ACL\HZ ACL'
$report = New-Item -Path .\ACL-APAC.CSV -ItemType file -Force
Add-Content -Path .\ACL-APAC.CSV -Value "GroupName,EmpNo,Name"

#方法一:(后写)
Import-Csv .\Groups.CSV | ForEach-Object {
    #下面这句获得组的名称,然后追加输出到CSV文件
    Get-ADGroup -Filter * -SearchBase $_.GroupName | select -ExpandProperty Name | Out-File $report -Encoding ASCII -Append
    #下面这个循环:将一个组中的每个成员的samAccountName, displayName存入变量$users
    ForEach-Object {
        $users = Get-ADGroup -Filter * -SearchBase $_.GroupName | Get-ADGroupMember | Get-ADUser -Properties samAccountName, displayName #| select -Property samAccountName, displayName
        #下面这个循环:将每个成员的samAccountName, displayName追加输出到CSV文件
        ForEach($user in $users) {
            "," + $user.samAccountName + "," + $user.displayName | Out-File $report -Encoding ASCII -Append
        }
    }
}
<#方法二:(先写)
Import-Csv .\Groups.CSV | ForEach-Object {
#下面是groupname的循环
    Get-ADGroup -Filter * -SearchBase $_.GroupName | select -ExpandProperty Name | Out-File $report -Encoding ASCII -Append
        #下面是group里成员的循环
        ForEach-Object {
            $MemberSummary = Get-ADGroupMember -Identity $_.GroupName | select -Property SamAccountName
                #下面是列出每个用户的完整属性
                ForEach ($Member in $MemberSummary) {
                    $MemberDetail = Get-ADUser -Identity $Member.SamAccountName -Properties Name, displayName
                        #下面是最终生成的CSV中真正的员工号，姓名那一行内容
                        ForEach-Object {
                            "," + $MemberDetail.Name + "," + $MemberDetail.DisplayName | Out-File $report -Encoding ASCII -Append
                            }
                }

        }

}
