- _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
]
-
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.
Nonprinting 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.
Nonprinting 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.
- 000 nul 001 soh 002 stx 003 etx 004 eot 005 enq

-
The default and supported byte counts for the conversion characters
are as follows:
- %_c , %_p , %_u , %c
-
One byte counts only.
-
%d , %i , %o
%u , %X , %x
-
- Four byte default, one, two and four byte counts supported.
-
%E , %e , %f
%G , %g
-
- Eight byte default, four byte counts supported.
The amount of data interpreted by each format string is the sum of the
data required by each format unit, which is the iteration count times the
byte count, or the iteration count times the number of bytes required by
the format if the byte count is not specified.
The input is manipulated in ``blocks'', where a block is defined as the
largest amount of data specified by any format string.
Format strings interpreting less than an input block's worth of data,
whose last format unit both interprets some number of bytes and does
not have a specified iteration count, have the iteration count
incremented until the entire input block has been processed or there
is not enough data remaining in the block to satisfy the format string.
If, either as a result of user specification or hexdump modifying
the iteration count as described above, an iteration count is
greater than one, no trailing whitespace characters are output
during the last iteration.
It is an error to specify a byte count as well as multiple conversion
characters or strings unless all but one of the conversion characters
or strings is
_a
or
_A
If, as a result of the specification of the
-n
option or end-of-file being reached, input data only partially
satisfies a format string, the input block is zero-padded sufficiently
to display all available data (i.e. any format units overlapping the
end of data will display some number of the zero bytes).
Further output by such format strings is replaced by an equivalent
number of spaces.
An equivalent number of spaces is defined as the number of spaces
output by an
s
conversion character with the same field width
and precision as the original conversion character or conversion
string but with any
``+
''
`` ''
``#
''
conversion flag characters
removed, and referencing a NULL string.
If no format strings are specified, the default display is equivalent
to specifying the
-x
option.
hexdump
exits 0 on success and >0 if an error occurred.
EXAMPLES
Display the input in perusal format:
"%06.6_ao " 12/1 "%3_u "
"\t\t" "%_p "
"\n"
Implement the -x option:
"%07.7_Ax\n"
"%07.7_ax " 8/2 "%04x " "\n"
