Execute "Get Info" on a file from command line in Mac OS X

"Here is my updated version of the script (including attribution to the original source, as I found it a couple of years ago). The main change in functionality is that it will handle pathnames that include characters that are not encoded identically between MacRoman and UTF-8 (anything outside ASCII).

#!/bin/sh
# Requires a POSIX-ish shell.

I know that I am not truly answering your question, but I get alot of the info I need from using ls -l and the file command.
