       od - dump files in octal and other formats

       od [OPTION]... [FILE]...
       od --traditional [FILE] [[+]OFFSET [[+]LABEL]]

       Write  an  unambiguous representation, octal bytes by default, of FILE
       to standard output.  With more than  one  FILE  argument,  concatenate
       them  in  the  listed  order to form the input.  With no FILE, or when
       FILE is -, read standard input.

       All arguments to long options are mandatory for short options.

       -A, --address-radix=RADIX
              decide how file offsets are printed

       -j, --skip-bytes=BYTES
              skip BYTES input bytes first

       -N, --read-bytes=BYTES
              limit dump to BYTES input bytes

       -s, --strings[=BYTES]
              output strings of at least BYTES graphic chars

       -t, --format=TYPE
              select output format or formats

       -v, --output-duplicates
              do not use * to mark line suppression

       -w, --width[=BYTES]
              output BYTES bytes per output line

              accept arguments in traditional form

       --help display this help and exit

              output version information and exit

   Traditional format specifications may be intermixed; they accumulate:
       -a     same as -t a,  select named characters

       -b     same as -t oC, select octal bytes

       -c     same as -t c,  select ASCII characters or backslash escapes

       -d     same as -t u2, select unsigned decimal shorts

       -f     same as -t fF, select floats

       -h     same as -t x2, select hexadecimal shorts

       -i     same as -t d2, select decimal shorts

       -l     same as -t d4, select decimal longs

       -o     same as -t o2, select octal shorts

       -x     same as -t x2, select hexadecimal shorts

       For older syntax (second call format), OFFSET means -j OFFSET.   LABEL
       is  the pseudo-address at first byte printed, incremented when dump is
       progressing.  For OFFSET and LABEL, a 0x or 0X prefix  indicates  hex-
       adecimal, suffixes may be . for octal and b for multiply by 512.

       TYPE is made up of one or more of these specifications:

       a      named character

       c      ASCII character or backslash escape

              signed decimal, SIZE bytes per integer

              floating point, SIZE bytes per integer

              octal, SIZE bytes per integer

              unsigned decimal, SIZE bytes per integer

              hexadecimal, SIZE bytes per integer

       SIZE  is  a  number.   For  TYPE  in  doux,  SIZE  may  also  be C for
       sizeof(char),  S  for  sizeof(short),  I  for  sizeof(int)  or  L  for
       sizeof(long).   If  TYPE is f, SIZE may also be F for sizeof(float), D
       for sizeof(double) or L for sizeof(long double).

       RADIX is d for decimal, o for octal, x for hexadecimal or n for  none.
       BYTES  is  hexadecimal  with  0x or 0X prefix, it is multiplied by 512
       with b suffix, by 1024 with k and by 1048576 with m.  Adding a z  suf-
       fix  to  any type adds a display of printable characters to the end of
       each line of output.  --string without a number  implies  3.   --width
       without a number implies 32.  By default, od uses -A o -t d2 -w 16.
