[GRLUG] need some script help

[Dave Chiodo]

Best to test.

As Michael suggested, use "echo" in place of the "mv" to see what will happen.

I might suggest you get in the habit of normalizing filenames of stuff
you download to avoid spaces and other "special" characters that can
cause problems.

There are various utilities than can help with that - search on google.
