| 22 For typical hex dump output formats by the UNIX and GNU/Linux tools ``hexdump``, | |
| 23 ``hd``, ``hexcat``, ``od`` and ``xxd``, and the DOS tool ``DEBUG``. For example: | |
| 24 | |
| 25 .. sourcecode:: hexdump | |
| 26 | |
| 27 00000000 7f 45 4c 46 02 01 01 00 00 00 00 00 00 00 00 00 |.ELF............| | |

| 29 | |
| 30 The specific supported formats are the outputs of: | |
| 31 | |
| 32 * ``hexdump FILE`` | |
| 33 * ``hexdump -C FILE`` -- the `canonical` format used in the example. | |
| 34 * ``hd FILE`` -- same as ``hexdump -C FILE``. | |
| 35 * ``hexcat FILE`` | |
| 36 * ``od -t x1z FILE`` | |
| 37 * ``xxd FILE`` | |
| 38 * ``DEBUG.EXE FILE.COM`` and entering ``d`` to the prompt. | |
