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.

       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

       --traditional
	      accept arguments in traditional form

       --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 ASCII 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

       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, incre‐
       mented 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.

       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).

       RADIX is d for decimal, o for octal, x for hexadecimal or n for none.  BYTES is hexadecimal with 0x or 0X prefix,  and  may
       have a multiplier suffix: b 512, kB 1000, K 1024, MB 1000*1000, M 1024*1024, GB 1000*1000*1000, G 1024*1024*1024, and so on
       for T, P, E, Z, Y.  Adding a z suffix to any type displays printable characters at the end of  each  output  line.   Option
       --string without a number implies 3; option --width without a number implies 32.  By default, od uses -A o -t oS -w16.
