PowerShell 更改文件和文件夹的所有者

Question

在网上搜索，我发现了 2 个能够更改文件和文件夹所有者的脚本。对此进行测试时，它在 PowerShell 1.0 中完美运行。现在我正在尝试将两者结合起来，以便它们递归地工作，因为我们有包含 500 多个子目录和文件的文件夹。这是一项艰巨的工作。

我们要:

在 \\server\C$\Folder 上运行一个脚本(不使用外部工具)

将所有文件和子文件夹的所有者更改为 BUILTIN\Administrators

问题:

每个脚本仅适用于 1 个文件或 1 个文件夹。如何将其组合在一个脚本中，以便将所有子文件夹和文件放在一起？可能将它放在 2 个不同的函数中并循环遍历它，或者..

Script1:将文件所有者更改为管理员

$File = "\\server\c$\Users\dir\Downloads\Target\TargetFile.txt"
$Account = New-Object System.Security.Principal.NTAccount("BUILTIN\Administrators")
$FileSecurity = new-object System.Security.AccessControl.FileSecurity
$FileSecurity.SetOwner($Account)
[System.IO.File]::SetAccessControl($File, $FileSecurity)

Script2:将文件夹所有者更改为管理员

Answer 1

您可以使用 SetOwner()文件夹的方法，就像文件一样。

# Define the owner account/group
$Account = New-Object -TypeName System.Security.Principal.NTAccount -ArgumentList 'BUILTIN\Administrators';

# Get a list of folders and files
$ItemList = Get-ChildItem -Path c:\test -Recurse;

# Iterate over files/folders
foreach ($Item in $ItemList) {
    $Acl = $null; # Reset the $Acl variable to $null
    $Acl = Get-Acl -Path $Item.FullName; # Get the ACL from the item
    $Acl.SetOwner($Account); # Update the in-memory ACL
    Set-Acl -Path $Item.FullName -AclObject $Acl;  # Set the updated ACL on the target item
}
