od


SYNOPSIS
       od [OPTION]... [FILE]...
       od [-abcdfilosx]... [FILE] [[+]OFFSET[.][b]]
       od --traditional [OPTION]... [FILE] [[+]OFFSET[.][b] [+][LABEL][.][b]]

DESCRIPTION
       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.

       If first and second call formats  both  apply,  the  second  format  is
       assumed  if the last operand begins with + or (if there are 2 operands)
       a  digit.   An  OFFSET  operand  means  -j  OFFSET.    LABEL   is   the
       pseudo-address  at  first  byte  printed, incremented when dump is pro-
       gressing.  For OFFSET and LABEL, a 0x or 0X prefix indicates  hexadeci-
       mal; suffixes may be . for octal and b for multiply by 512.

       Mandatory  arguments  to  long  options are mandatory for short options
       too.

       -A, --address-radix=RADIX
              output format for file offsets.  RADIX is  one  of  [doxn],  for
              Decimal, Octal, Hex or None

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

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

       -S BYTES, --strings[=BYTES]
              output  strings  of  at least BYTES graphic chars.  3 is implied
              when BYTES is not specified

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

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

       -w[BYTES], --width[=BYTES]
              output BYTES bytes per output line.  32 is implied when BYTES is
              not specified

       --traditional
              accept arguments in third form above

       --help display this help and exit

       --version
              output version information and exit


       -l     same as -t dL, select decimal longs

       -o     same as -t o2, select octal 2-byte units

       -s     same as -t d2, select decimal 2-byte units

       -x     same as -t x2, select hexadecimal 2-byte units

   TYPE is made up of one or more of these specifications:
       a      named character, ignoring high-order bit

       c      ASCII character or backslash escape

       d[SIZE]
              signed decimal, SIZE bytes per integer

       f[SIZE]
              floating point, SIZE bytes per integer

       o[SIZE]
              octal, SIZE bytes per integer

       u[SIZE]
              unsigned decimal, SIZE bytes per integer

       x[SIZE]
              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).

       Adding a z suffix to any type displays printable characters at the  end
       of each output line.

   BYTES is hex with 0x or 0X prefix, and may have a multiplier suffix:
       b      512

       KB     1000

       K      1024

       MB     1000*1000

       M      1024*1024

       and so on for G, T, P, E, Z, Y.
