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 op-
       erand begins with + or (if there are 2 operands) a digit.  An OFFSET operand means -j OFF-
       SET.   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 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 hexadeci-
       mal 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.
