Greetings, dave_the_m.

The OP (pimperator) mentions Super User twice in the post.

“...the user has super-user privileges...”
and
“After doing some reading I see that unlink() will not work if the file is open or if the user doesn't have superuser privileges, which is not the case for both.”
Which is why I felt it pertinent to mention the -U flag.
