I have a folder with numerous ACL permissions set. Most of these include
directory_inherit permissions and therefore should be, and are, automatically propagated to any new sub-folders and files I create within that folder.
However, there are some sub-folders and files that were already in the folder with the ACL permissions before the ACL permissions were set. Because of this, they don't have the inheritable permissions.
How can I make all the pre-existing sub-folders and files inherit the inheritable ACL permissions, as if they were newly created?
