Question: how do I remove a directory the system thinks is not empty? OSX 10.12
I have a directory in the trash that cannot be deleted and it has no files in it. How can I force delete it?
The system under Terminal complains the directory is not empty, but no files appear there. On the GUI, it complains another program is using the directory, but nothing is running.
