You're right - just "script" then. I'm not dissing magic - it's a good starting point in forensics or to see what's in a bin directory, but shouldn't be relied on (also see ftimes xmagic for a more featureful magic implementation w/e sf comes back up). My point is that you can't determine what you're looking at w/o being told (an extension) or looking at it. So (my original point) you loose data by removing/not having an extension.
