Question

我对PowerShell脚本编写很新（自从我开始学习powershell以来将近1个月。）

我目前正在使用powershell 2.0编写一个脚本来清理文件夹NTFS ACL。我想删除除管理员之外的每个acl。

我的问题是我无法找到一种方法来删除不是管理员的每个acl，而不知道它们。

所以我来到这里寻找powershell pro。

Answer 1

此代码删除acl：

$acl = Get-Acl \\remote_server\share_folder\HAL.9000
$acl.Access | %{$acl.RemoveAccessRule($_)}

此代码添加管理员acl：

#BUILTIN administrator

$acl = Get-Acl \\remote_server\share_folder\HAL.9000
$permission  = "BUILTIN\Administrators","FullControl", "ContainerInherit,ObjectInherit","None","Allow"
$accessRule = New-Object System.Security.AccessControl.FileSystemAccessRule $permission
$acl.SetAccessRule($accessRule)
Set-Acl \\remote_server\share_folder\HAL.9000 $acl

#Domain controller administrator

$acl = Get-Acl \\remote_server\share_folder\HAL.9000
$permission  = "DOMAINCONTROLLER\Administrators","FullControl", "ContainerInherit,ObjectInherit","None","Allow"
$accessRule = New-Object System.Security.AccessControl.FileSystemAccessRule $permission
$acl.SetAccessRule($accessRule)
Set-Acl \\remote_server\share_folder\HAL.9000 $acl

希望这会有所帮助：）

为方便起见，我将所有这些东西复制/粘贴在一个函数中。如果它对任何人都有用，那么它就是：

Function Remove-ACL {    
    [CmdletBinding(SupportsShouldProcess=$True)]
    Param(
        [parameter(Mandatory=$true,ValueFromPipeline=$true,Position=0)]
        [ValidateNotNullOrEmpty()]
        [ValidateScript({Test-Path $_ -PathType Container})]
        [String[]]$Folder,
        [Switch]$Recurse
    )

    Process {

        foreach ($f in $Folder) {

            if ($Recurse) {$Folders = $(Get-ChildItem $f -Recurse -Directory).FullName} else {$Folders = $f}

            if ($Folders -ne $null) {

                $Folders | ForEach-Object {

                    # Remove inheritance
                    $acl = Get-Acl $_
                    $acl.SetAccessRuleProtection($true,$true)
                    Set-Acl $_ $acl

                    # Remove ACL
                    $acl = Get-Acl $_
                    $acl.Access | %{$acl.RemoveAccessRule($_)} | Out-Null

                    # Add local admin
                    $permission  = "BUILTIN\Administrators","FullControl", "ContainerInherit,ObjectInherit","None","Allow"
                    $rule = New-Object System.Security.AccessControl.FileSystemAccessRule $permission
                    $acl.SetAccessRule($rule)

                    Set-Acl $_ $acl

                    Write-Verbose "Remove-HCacl: Inheritance disabled and permissions removed from $_"
                }
            }
            else {
                Write-Verbose "Remove-HCacl: No subfolders found for $f"
            }
        }
    }
}

<强>用法：

# For only one folder:
Remove-ACL 'C:\Folder' -Verbose

# For all subfolders:
Remove-ACL 'C:\Folder' -Recurse -Verbose

# Pipe stuff
'C:\Folder 1', 'C:\Folder 2' | Remove-ACL -Verbose

此代码删除acl：$ acl = Get-Acl \ remote_server \ share_folder \ HAL.9000 $ acl.Access | ％{$ acl.RemoveAccessRule（$ _）}

直到你做

才行

Set-Acl \\remote_server\share_folder\HAL.9000 $acl

为什么不创建新列表。例如：

$identity = New-Object System.Security.Principal.NTAccount('NT AUTHORITY\SYSTEM')
$acl = New-Object System.Security.AccessControl.DirectorySecurity
$acl.SetOwner($identity)
$acl.SetGroup($identity)
$rule = New-Object System.Security.AccessControl.FileSystemAccessRule('NT AUTHORITY\SYSTEM', ’FullControl’, ’ContainerInherit, ObjectInherit’, ’None’,’Allow’)
$acl.AddAccessRule($rule)
$rule = New-Object System.Security.AccessControl.FileSystemAccessRule('BUILTIN\Administrators', ’FullControl’, ’ContainerInherit, ObjectInherit’, ’None’, ’Allow’)
$acl.AddAccessRule($rule)
Set-Acl -LiteralPath "C:\MyFolder" -AclObject $acl
Get-Acl -LiteralPath "C:\MyFolder" | Format-List

使用powershell删除文件夹上的所有ACL
