I have a directory, X, which contains many subdirectories (millions of them), which contain files. I have read access to some, but not all, directories and files contained therein.

I need to compile a list of directories and files under X which I don't have permission to read.

How could I go about this?

You can do that with this simple find command :

find . ! -readable

Pay attention to use it as your user and not as root or all files would appear as readable...
