NAME

       od - dump files in octal and other formats

SYNOPSIS

       od [OPTION]... [FILE]...
       od --traditional [FILE] [[+]OFFSET [[+]LABEL]]

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

       -b     same as -t oC, select octal bytes

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

       -d     same as -t u2, select unsigned decimal shorts

       -f     same as -t fF, select floats

       -h     same as -t x2, select hexadecimal shorts

       -i     same as -t d2, select decimal shorts

       -l     same as -t d4, select decimal longs

       -o     same as -t o2, select octal shorts

       -x     same as -t x2, select hexadecimal shorts

       For older syntax (second call format), OFFSET 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.

       TYPE is made up of one or more of these specifications:

       a      named character

       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, it is multiplied  by  512
       with  b	suffix,  by 1024 with k and by 1048576 with m.	Adding a z suffix to any type adds a display of printable characters to the end of
       each line of output.  --string without a number implies 3.  --width without a number implies 32.  By default, od uses -A o -t d2 -w 16.
