Here’s something I had to do at work a few weeks back. I wanted to blog about it since then but never got around to it.<\/p>\n
We had copied a bunch of folders from one location to another. Since this was a copy the folders lost their original ACLs. I wanted to do two things – 1) the folder names were in the format “LastName, FirstName” and I wanted to change that to “username” (I had a CSV file with mappings so I could use that to do the renaming). 2) I wanted to change the ACLs so the user had modify rights to the folders.<\/p>\n
For the first task here’s what I did:<\/p>\n
$Mappings=@{}\r\nforeach($r in (Import-Csv \\path\\to\\Mappings.csv))\r\n{\r\n $Mappings[$r.Olduser]=$r.NewUser\r\n}\r\n\r\nforeach ($folder in \"G:\\Folder1\",\"G:\\Folder2\") { \r\n Get-ChildItem $folder -Directory | %{ \r\n $oldPath = $_.FullName;\r\n $oldUser = Split-Path -Leaf $oldPath;\r\n $newUser = $Mappings[$oldUser];\r\n if ($newUser -ne $null) { \r\n $newPath = \"G:\\NewFolder\\$newUser\"\r\n # Write-Host \"Will move from $oldPath to $newPath\"\r\n Move-Item $oldPath $newPath\r\n }\r\n }\r\n}<\/pre>\nNote that apart from renaming I also move the folder to a different path (coz I had multiple source locations and wanted to combine them all into one).<\/p>\n
For the second task here’s what I did:<\/p>\n
$HomeFolders = Get-ChildItem G:\\NewFolder -Directory\r\nforeach ($HomeFolder in $HomeFolders) {\r\n $Path = $HomeFolder.FullName\r\n $Acl = (Get-Item $Path).GetAccessControl('Access')\r\n $Username = $HomeFolder.Name\r\n $Ar = New-Object System.Security.AccessControl.FileSystemAccessRule($Username, 'Modify', 'ContainerInherit,ObjectInherit', 'None', 'Allow')\r\n $Acl.SetAccessRule($Ar)\r\n Set-Acl -path $Path -AclObject $Acl\r\n}<\/pre>\nLater on I realized the folders still had the BUILTIN\\Users<\/code> entity with full control so I had to remove these too. The code for that was slightly different so here goes:<\/p>\n$HomeFolders = Get-ChildItem G:\\NewFolder -Directory\r\nforeach ($HomeFolder in $HomeFolders) {\r\n $change = $false;\r\n $Path = $HomeFolder.FullName\r\n $Acl = (Get-Item $Path).GetAccessControl('Access')\r\n foreach ($value in $Acl.Access) { \r\n if ($value.IdentityReference -eq \"BUILTIN\\Users\") { $Acl.RemoveAccessRule($value); $change=$true; } \r\n }\r\n if ($change) { Set-Acl -Path $Path -AclObject $Acl } \r\n}<\/pre>\nThis<\/a> is a good article on what I was doing above. And this TechNet article<\/a> is a useful resource on the various rights that can be assigned.<\/p>\n","protected":false},"excerpt":{"rendered":"Here’s something I had to do at work a few weeks back.
