I am trying to delete a directory stored on a Windows 2008 R2 server, mounted on a Mac as network home (10.8.5). The directory was created by Safari and stores temporary internet files. I need to be able to delete this folder on logout from a Mac bash script.

The Terminal on Mac shows the directory as empty:

36W-FacRm-02:History lwickham$ cd /home/lwickham/Library/Caches/Metadata/Safari/History
36W-FacRm-02:History lwickham$ ls -al
total 0
drwx------ 1 lwickham CGPS\Domain Users 264 Nov 8 09:24 .
drwx------ 1 lwickham CGPS\Domain Users 264 Nov 8 09:28 ..

However, on the Windows server it has a single 0kb file that doesn't start with a "." but yet is invisible to the Mac.

E:\FacultyHome2\lwickham\Library\Caches\Metadata\Safari\History>dir
 Volume in drive E is FacultyUsers2
 Volume Serial Number is 8C17-4EF3

 Directory of E:\FacultyHome2\lwickham\Library\Caches\Metadata\Safari\History

All my attempts to delete the dir from the Mac have failed:
