## hexdump (#171)

_Quiz idea provided by Robert Dober._

This week's quiz should be quick and easy for experienced Rubyists,
and a good lesson for beginners. Your task this week is to write a
utility that outputs a hex dump of the input.

There are a number of hex dump utilities in existence, that go by the
names `hd`, `od`, `hexdump`... I'm sure there are more. Pick one you'd
like to reproduce: If you're on any variety of Unix or BSD (including
Mac OS X), you can get man pages from the command-line to see how they
work. On Windows, if you don't have one installed, you can check out
this [man page for hexdump][1] and use that as a model.

You are not required to implement all the various command-line
switches, but I should be able to run your script on a file and, as a
minimum, see output resembling this (view with fixed-width font for
best results):

Your submission should accept input either from a named file (part of
the command-line arguments) or from standard input if no filename is
provided.

Finally, when submitting, make sure to describe what existing hex dump
program you are emulating/reproducing (if any), and what arguments to
your script are needed, if any, to produce the basic output above.
