PoweShell Script for Disabling Inheritance on Subfolders

This may point you in the right direction;

http://jeffwouters.nl/index.php/2014/05/powershell-function-to-configure-inheritance-on-folders/

pipe your get child item into a where item equal a folder then do a foreach  and reset the permission

gci -Path c:\somefolder -recurse | where { $_.PsIsContainer } | % {
	$acl = Get-Item $_ | get-acl
	$acl.SetAccessRuleProtection($true, $true)
	$acl | Set-Acl
}

Select allOpen in new window

Thanks just to confirm this will DISABLE inheritance on the child folders?

Yes.

so the script will enumerate all child folders within the parent folder specified.

gci c:\parentfolder - recurse 

Select allOpen in new window

It will verify it is only running against folders

| where { $_.PsIsContainer }

Select allOpen in new window

Then for each folder it finds no matter how many levels deep it will disable inheritance.

$acl.SetAccessRuleProtection($true, $true)

Select allOpen in new window

If we want to limit recursion we can specify how many folders deep we go e.g.:

gci c:\parentfolder\*\*\*

Select allOpen in new window

will return two folders deep add an additional \*  for each level deeper you want to recurse.

Thanks. I would only want to disable inheritance on the child folder but not the grandchildren. What would this syntax look like?
