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 as-
       sumed 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  OFF-
       SET 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 Dec-
	      imal, 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 float

       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.	Binary	prefixes  can  be  used,  too:
       KiB=K, MiB=M, and so on.

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

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