+# Create a view
+
+With Powershell you can also shows your users all files with unique permissions. The following script creates a view in your library that displays files with different permissions than the entire library.
+
+
+```Powershell
+
+# Define the list name and site URL
+$listName = "YourListName"
+$siteUrl = "https://yourtenant.sharepoint.com/sites/yoursite"
+

+
+# Connect to the SharePoint site
+Connect-PnPOnline -Url $siteUrl -UseWebLogin

+$existingColumns = Get-PnPField -List $listName
+if (-not $existingColumns.InternalName -contains $columnInternalName) {
+    Add-PnPField -List $listName -InternalName $columnInternalName -DisplayName $columnDisplayName -Type Boolean
+    Write-Host "Boolean column '$columnDisplayName' added to the list."
+} else {
+    Write-Host "Boolean column '$columnDisplayName' already exists."
+}
+
+# Get all list items
