19 For typical hex dump output formats by the UNIX and GNU/Linux tools ``hexdump``, 

20 ``hd``, ``hexcat``, ``od`` and ``xxd``, and the DOS tool ``DEBUG``. For example: 

21 

22 .. sourcecode:: hexdump 

23 

24 00000000 7f 45 4c 46 02 01 01 00 00 00 00 00 00 00 00 00 |.ELF............|

26 

27 The specific supported formats are the outputs of: 

28 

29 * ``hexdump FILE`` 

30 * ``hexdump -C FILE`` -- the `canonical` format used in the example. 

31 * ``hd FILE`` -- same as ``hexdump -C FILE``. 

32 * ``hexcat FILE`` 

33 * ``od -t x1z FILE`` 

34 * ``xxd FILE`` 

35 * ``DEBUG.EXE FILE.COM`` and entering ``d`` to the prompt.
