   Conversion strings
       The hexdump utility also supports the following additional
       conversion strings.

       _a[dox]
           Display the input offset, cumulative across input files, of
           the next byte to be displayed. The appended characters d, o,
           and x specify the display base as decimal, octal or
           hexadecimal respectively.

       _A[dox]
           Almost identical to the _a conversion string except that it
           is only performed once, when all of the input data has been
           processed.

       _c
           Output characters in the default character set. Non-printing
           characters are displayed in three-character, zero-padded
           octal, except for those representable by standard escape
           notation (see above), which are displayed as two-character
           strings.

       _p
           Output characters in the default character set. Non-printing
           characters are displayed as a single '.'.

       _u
           Output US ASCII characters, with the exception that control
           characters are displayed using the following, lower-case,
           names. Characters greater than 0xff, hexadecimal, are
           displayed as hexadecimal strings.

   Colors
       When put at the end of a format specifier, hexdump
       highlights the respective string with the color
       specified. Conditions, if present, are evaluated prior
       to highlighting.

       _L[color_unit_1,color_unit_2,...,color_unit_n]

       The full syntax of a color unit is as follows:

       [!]COLOR[:VALUE][@OFFSET_START[-END]]

       !
           Negate the condition. Please note that it only makes
           sense to negate a unit if both a value/string and an
           offset are specified. In that case the respective
           output string will be highlighted if and only if the
           value/string does not match the one at the offset.

       COLOR
           One of the 8 basic shell colors.

       VALUE
           A value to be matched specified in hexadecimal, or
           octal base, or as a string. Please note that the
           usual C escape sequences are not interpreted by
           hexdump inside the color_units.

       OFFSET
           An offset or an offset range at which to check for a
           match. Please note that lone OFFSET_START uses
