使用嵌套的foreach將用戶文件夾複製到新文件夾

Question

我正在嘗試將c：\ users文件夾複製到robocopy的新目標。事情是我的嵌套foreach說法錯在這裏：

$users = @(
    'jack' 
    'Jon' 
) 
$news = @(
    'jacknew' 
    'JonNew' 
) 

foreach ($userx in $users) { 
    foreach ($new in $news) { 
     $source = "c:\users\$($userx)" 
     $destination = "d:\users\$($new)" 

     robocopy $source $destination /MIR /LOG:c:\robocopy.txt /NP 
    } 
} 

它拷貝這兩個文件夾到d：\ jacknew文件夾中。

Answer 1

你有兩個foreach循環，所以你將執行robocopy 4次：如果你想jack和jon複製到相應的文件夾jacknew和jonnew

robocopy c:\users\jack d:\users\jacknew /MIR /LOG:c:\robocopy.txt /NP 
robocopy c:\users\jack d:\users\jonnew /MIR /LOG:c:\robocopy.txt /NP 
robocopy c:\users\Jon d:\users\jacknew /MIR /LOG:c:\robocopy.txt /NP 
robocopy c:\users\Jon d:\users\jonnew /MIR /LOG:c:\robocopy.txt /NP 

，你可以使用一個foreach循環，只是追加new複製時;例如：

$users = @(
    'jack' 
    'Jon' 
    ) 
    foreach ($user in $users) { 
     $source = "c:\users\$($user)" 
     $destination = "d:\users\$($user)new" 
     robocopy $source $destination /MIR /LOG:c:\robocopy.txt /NP 
    }
