That won't work, at least, not in the way you have it now. To run a command on one machine from another, you must use something like SSH or Telnet.
But if I'm understanding your intention correctly, you want to search your Windows flesystem using a Unix machine. Unfortunately, it's not that simple, unless you have already mounted your Windows drive using Samba(or something like that).
Instead, consider using File::Find, and then unlinking the file you want to remove.
