PowerShell更改文件和文件夹的所有者

标签： powershell

在网上搜索，我找到了2个能够更改文件和文件夹所有者的脚本。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，以便它们以递归方式工作，因为我们的文件夹中包含超过500个子目录和文件。这是一项艰巨的任务......

我们希望：

  • 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。如何将它组合在一个脚本中，以便将所有子文件和文件组合在一起？将其置于2个不同的功能中可以循环使用它或..

脚本1：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)

脚本2：将文件夹所有者更改为管理员

您可以对文件夹使用SetOwner()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
}

在使用PowerShell一周后，我找到了自己问题的答案：

#$Target = "\\domain.net\dir"

# Change FOLDER owners to Admin
$Folders = @(Get-ChildItem -Path $Target -Directory -Recurse | Select-Object -ExpandProperty FullName)
echo $Folders
foreach ($Item1 in $Folders) 
{
# Action

再次感谢大家的帮助。希望其他人可以从我的PowerShell研究中受益。唯一的想法就是让它变得更加冗长，但这又是另一天。它做了它需要做的事情，并且在最严苛的条件下，权限真的搞砸了。
