Can PowerShell trap errors in GetChildItem and continue looping?

Question:

I have a PowerShell script that is recursing down thru the file system using GetChildItem in a for-loop. As it travels, it is fixing ACL issues it finds (mostly where someone has blocked the BUILTIN\Administrators account)… but there are some it can’t handle on it’s own, like when I get [System.UnauthorizedAccessException] if there is an explicit “Deny” ACE.

The line of code looks like this:

When it stumbles on a path it can’t read, it gives this exception:

Get-ChildItem : Access to the path ‘C:\TEMP\denied’ is denied. At
Fix-ACLs.ps1:52 char:31
+ foreach($file in Get-ChildItem <<<< $dirRoot -Recurse -ErrorAction
Continue) {
+ CategoryInfo : PermissionDenied:
(C:\TEMP\denied:String) [Get-ChildItem], Unauthorized AccessException
+ FullyQualifiedErrorId :
DirUnauthorizedAccessError,Microsoft.PowerShell.Commands.GetChildItemCommand

I would like to try/catch or trap the error so that I can repair the ACL (that is, remove the “Deny”) in-place, and–most importantly–continue the loop without losing my place. Any suggestions for me?
