I have an external drive hooked up to my Mac, and I'm trying to determine things like, e.g., is this HFS or FAT, is it 32-bit or 64-bit, etc. It seems like there should be some trivial command that gives me this info, but I can't seem to find one. Ideas?

          Highlight the volume in finder (note, that it must be the root of the volume), and hit cmd + i. The info dialog that appears shows you the filesystem type against the Format label.

            Unless you're wedded to doing it from the command line, use Disk Utility and it's "Info" button.
