20 For typical hex dump output formats by the UNIX and GNU/Linux tools ``hexdump``,
21 ``hd``, ``hexcat``, ``od`` and ``xxd``, and the DOS tool ``DEBUG``. For example:

28 The specific supported formats are the outputs of:
29
30 * ``hexdump FILE``
31 * ``hexdump -C FILE`` -- the `canonical` format used in the example.
32 * ``hd FILE`` -- same as ``hexdump -C FILE``.
33 * ``hexcat FILE``
34 * ``od -t x1z FILE``
35 * ``xxd FILE``
36 * ``DEBUG.EXE FILE.COM`` and entering ``d`` to the prompt.
