The 'cd /' is just the command to change the working directory to the root of the filesystem. Maybe your terminal window started you in the root so changing to it wasn't necessary. My terminal defaults to my home folder, so that's why I had to do the cd /.
I'm assuming that the file is no longer listed in your stacks?

Yep, it's gone from Stacks. I even turned on the hidden files to make sure it was still "there."
Thanks for the help.
