NAME

   od - dump files in octal and other formats

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
   progressing.   For  OFFSET  and  LABEL,  a  0x  or  0X prefix indicates
   hexadecimal; 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

   --endian={big|little}
          swap input bytes according the specified order

   -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

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

   -b     same as -t o1, select octal bytes

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

   -d     same as -t u2, select unsigned decimal 2-byte units

   -f     same as -t fF, select floats

   -i     same as -t dI, select decimal ints

   -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      printable 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.

EXAMPLES

   od -A x -t x1z -v
          Display hexdump format output

   od -A o -t oS -w16
          The default output format used by od
