Powershell 需要逗号将SamAccountName与组分开

我有这个脚本来提取以字母“m”开头的用户以及他们所属的组。脚本的结果是可以的，但我需要

SamAccountName

和组在同一行上，并用逗号分隔，以便在Excel文件中更好地排列它。有什么建议吗

Import-Module activedirectory

$file=".\atos_user_m.csv"

foreach ($suser in (Get-ADUser -Filter {samaccountname -like "m*"})) {
    $user = $suser.SamAccountName
    echo "`r`n"$user"`r`n" | Out-File $file -Append
    foreach ($group in (Get-ADPrincipalGroupMembership -Identity $user)) {
        $group.SamAccountName | Out-File $file -Append
    }
}

只需在组之前添加$user

import-module activedirectory
$file=".\atos_user_m.csv"

foreach ($suser in (get-aduser -filter {samaccountname -like "m*"})) {
    $user = $suser.samaccountName
    foreach ($group in (Get-ADPrincipalGroupMembership -Identity $user)) {
        $user + ',' + $group.SamAccountName  | out-file -filepath $file -append
    }
}

如果希望给定用户的所有组与用户名位于同一行，可以执行以下操作：

foreach ($suser in (Get-ADUser -Filter {samaccountname -like "m*"})) {
    $user = $suser.SamAccountName
    $groups = Get-ADPrincipalGroupMembership -Identity $user |
              Select-Object -Expand SamAccountName
    '{0},{1}' -f $user, ($groups -join ',') | Out-File $file -Append
}

或者像这样（使用管道）：

我试了第一个，这正是我需要的。谢谢你的帮助。

Get-ADUser -Filter {samaccountname -like "m*"} | ForEach-Object {
    $groups = Get-ADPrincipalGroupMembership -Identity $_.SamAccountName |
              Select-Object -Expand SamAccountName
    '{0},{1}' -f $_.SamAccountName, ($groups -join ',')
} | Out-File $file
