A More Complex Case: rm-rf-with-file.t (continued 8)

• The case where I have read and write permissions on the third-level subdirectory -- but not execute permissions -- is similar to the case where I had read-only permssions.

• I can see that there is something called a inside that directory

        $ ls -l foo_10237_0600/
        ls: cannot access 'foo_10237_0600/a': Permission denied
        total 0
        -????????? ? ? ? ?            ? a

• Benefit of the read permission

• But I can't see any of that file's metadata and I am denied permission to that file itself

• Cost of not having execute permissions on the directory.
