Certainly! Here's a one-line PowerShell script that will recursively find all folders with at least one deny permission in the DACL (Discretionary Access Control List) list:@AssistGPT please, write one-line powershell script to find recursively all folders having at least one deny permission in DACL list.
Get-ChildItem -Directory -Recurse | ForEach-Object { $folder = $_; $acl = Get-Acl -Path $folder.FullName; $acl.Access | Where-Object { $_.AccessControlType -eq 'Deny' } | Select-Object -First 1 | Select-Object @{Name='Folder';Expression={$folder.FullName}} }
Get-ChildItem
cmdlet to recursively retrieve all directories. For each directory, it retrieves the DACL using Get-Acl
and then filters the access control entries (ACEs) to find any entries with an access control type of 'Deny'. Finally, it selects the first deny entry found and outputs the folder's full name.Select-Object -First 1
part from the script.To prevent the script from stopping execution when encountering an "Access Denied" error, you can use the@AssistGPT, how to prevent script from stopping execution on access denied error?
-ErrorAction
parameter with the value "SilentlyContinue" or "Continue". This will instruct PowerShell to continue executing the script even if an error occurs.-ErrorAction
parameter:Get-ChildItem -Directory -Recurse | ForEach-Object {
$folder = $_
$acl = $null
$acl = Get-Acl -Path $folder.FullName -ErrorAction SilentlyContinue
if ($acl) {
$acl.Access | Where-Object { $_.AccessControlType -eq 'Deny' } | Select-Object -First 1 | Select-Object @{Name='Folder';Expression={$folder.FullName}}
}
}
-ErrorAction SilentlyContinue
parameter is added to the Get-Acl
cmdlet. If an "Access Denied" error occurs, it will be silently ignored, and the script will continue executing.Apologies for the oversight. To include all folders, including those with hidden and system attributes, you can modify the script to use the@AssistGPT, Please, include really all folders. That means you should not omit folder with hidden and system attributes.
Get-ChildItem
cmdlet with the -Force
parameter. This will ensure that hidden and system folders are also included in the search.Get-ChildItem -Directory -Recurse -Force | ForEach-Object {
$folder = $_
$acl = $null
$acl = Get-Acl -Path $folder.FullName -ErrorAction SilentlyContinue
if ($acl) {
$acl.Access | Where-Object { $_.AccessControlType -eq 'Deny' } | Select-Object -First 1 | Select-Object @{Name='Folder';Expression={$folder.FullName}}
}
}
-Force
parameter to Get-ChildItem
, the script will now include all folders, regardless of their attributes.Certainly! To redirect all console output to a file named "logfile.txt", you can use the@AssistGPT, Please, redirect all console output to a file logfile.txt
>
operator in PowerShell. Here's the modified script:Get-ChildItem -Directory -Recurse -Force | ForEach-Object {
$folder = $_
$acl = $null
$acl = Get-Acl -Path $folder.FullName -ErrorAction SilentlyContinue
if ($acl) {
$acl.Access | Where-Object { $_.AccessControlType -eq 'Deny' } | Select-Object -First 1 | Select-Object @{Name='Folder';Expression={$folder.FullName}}
}
} > logfile.txt
>
operator is used to redirect the output of the entire script to the "logfile.txt" file. Any output that would have been displayed in the console will now be written to the file instead.Certainly! To include the deny SDDL (Security Descriptor Definition Language) string next to the folder path found, you can modify the script to retrieve the SDDL string from the deny access control entry (ACE). Here's the updated script:@AssistGPT, Please, write deny SDDL string next to the folder path found.
Get-ChildItem -Directory -Recurse -Force | ForEach-Object {
$folder = $_
$acl = $null
$acl = Get-Acl -Path $folder.FullName -ErrorAction SilentlyContinue
if ($acl) {
$denyACE = $acl.Access | Where-Object { $_.AccessControlType -eq 'Deny' } | Select-Object -First 1
if ($denyACE) {
$folder.FullName + " - " + $denyACE.FileSystemRights + " - " + $denyACE.IdentityReference.Value + " - " + $denyACE.AccessControlType + " - " + $denyACE.IsInherited
}
}
} > logfile.txt
Certainly! To limit the depth of child subfolders to traverse by 4 levels and exclude symlinks, you can modify the script by adding the@AssistGPT, can limit the depth of child subfolders to traverse by 4 levels?
Also, please exclude symlinks.
-Depth
parameter and using the Get-ChildItem
cmdlet with the -Directory
and -Attributes
parameters. Here's the updated script:Get-ChildItem -Directory -Recurse -Force -Depth 4 -Attributes !ReparsePoint | ForEach-Object {
$folder = $_
$acl = $null
$acl = Get-Acl -Path $folder.FullName -ErrorAction SilentlyContinue
if ($acl) {
$denyACE = $acl.Access | Where-Object { $_.AccessControlType -eq 'Deny' } | Select-Object -First 1
if ($denyACE) {
$folder.FullName + " - " + $denyACE.FileSystemRights + " - " + $denyACE.IdentityReference.Value + " - " + $denyACE.AccessControlType + " - " + $denyACE.IsInherited
}
}
} > logfile.txt
-Depth 4
parameter limits the traversal to 4 levels deep from the starting directory. The -Attributes !ReparsePoint
parameter excludes symlinks by filtering out any items with the "ReparsePoint" attribute.Certainly! To reference the "logfile.txt" file located on the current user's Desktop, you can modify the script to use the appropriate path. Here's the updated script:@AssistGPT, please reference to logfile.txt like that it located on the current user's Desktop.
$desktopPath = [Environment]::GetFolderPath("Desktop")
$logFilePath = Join-Path -Path $desktopPath -ChildPath "logfile.txt"
Get-ChildItem -Directory -Recurse -Force -Depth 4 -Attributes !ReparsePoint | ForEach-Object {
$folder = $_
$acl = $null
$acl = Get-Acl -Path $folder.FullName -ErrorAction SilentlyContinue
if ($acl) {
$denyACE = $acl.Access | Where-Object { $_.AccessControlType -eq 'Deny' } | Select-Object -First 1
if ($denyACE) {
$folder.FullName + " - " + $denyACE.FileSystemRights + " - " + $denyACE.IdentityReference.Value + " - " + $denyACE.AccessControlType + " - " + $denyACE.IsInherited
}
}
} > $logFilePath
$desktopPath
variable is used to retrieve the path to the current user's Desktop folder using the [Environment]::GetFolderPath("Desktop")
method. The $logFilePath
variable is then set to the path of the "logfile.txt" file on the Desktop by joining the $desktopPath
with the filename using the Join-Path
cmdlet.$desktopPath
variable accordingly.Apologies for the confusion. If you specifically need the raw SDDL string instead of the description of access permissions, you can modify the script accordingly. Here's the updated script:@AssistGPT, the script provided will output description of access permissions instead of raw SDDL string I requested. Can you fix that?
$desktopPath = [Environment]::GetFolderPath("Desktop")
$logFilePath = Join-Path -Path $desktopPath -ChildPath "logfile.txt"
Get-ChildItem -Directory -Recurse -Force -Depth 4 -Attributes !ReparsePoint | ForEach-Object {
$folder = $_
$acl = $null
$acl = Get-Acl -Path $folder.FullName -ErrorAction SilentlyContinue
if ($acl) {
$denyACE = $acl.Access | Where-Object { $_.AccessControlType -eq 'Deny' } | Select-Object -First 1
if ($denyACE) {
$folder.FullName + " - " + $denyACE.Sddl
}
}
} > $logFilePath
Sddl
property is used to retrieve the raw SDDL string for the deny access control entry (ACE). The script will now output the folder path followed by the raw SDDL string to the "logfile.txt" file located on the current user's Desktop.Certainly! To allow for manual specification of the full path to the folder you want to start the search from, you can modify the script to include a parameter that accepts the folder path as input. Here's the updated script:@AssistGPT Please provide a way to specify manually the full path to the folder we want to start search from.
param (
[Parameter(Mandatory=$true)]
[string]$FolderPath
)
$desktopPath = [Environment]::GetFolderPath("Desktop")
$logFilePath = Join-Path -Path $desktopPath -ChildPath "logfile.txt"
Get-ChildItem -Directory -Recurse -Force -Depth 4 -Attributes !ReparsePoint -Path $FolderPath | ForEach-Object {
$folder = $_
$acl = $null
$acl = Get-Acl -Path $folder.FullName -ErrorAction SilentlyContinue
if ($acl) {
$denyACE = $acl.Access | Where-Object { $_.AccessControlType -eq 'Deny' } | Select-Object -First 1
if ($denyACE) {
$folder.FullName + " - " + $denyACE.Sddl
}
}
} > $logFilePath
$FolderPath
parameter is added to the script using the param
block. This parameter is marked as mandatory (Mandatory=$true
) to ensure that the user provides a value for it.Get-ChildItem
cmdlet is then modified to include the -Path $FolderPath
parameter, which specifies the folder path provided by the user..\script.ps1 -FolderPath "C:\Path\To\Folder"
