I meant to say filename I wasn't paying enough attention. Thank you for pointing this out :)

in the link I provided I made it clear what my intentions were, but I guess I should have proof read.

You could use (without tr) for f in * ; do mv "$f" "${f// /-}" ; done Note that it doesn't remove any other special character.
