I've almost found a way to have GUI programs call command line programs. If you open the terminal, and type
then /bin/ls will be opened using Terminal.app. Since it's an executable, it will create a new window and run it. So if we make an AppleScript that tells Terminal.app to open the executable, it should run the program. I've still got a couple problems, though. First, I can't figure out how to tell Terminal.app what size to create the new window. Second, I'm not an AppleScript master, and I'm having problems telling Terminal.app what file to run. Does anyone else know how to do either of these? It would be nice to have some command line apps assigned as internet file helpers.
open -a /Applications/Utilities/Terminal.app /bin/ls
