NAME    [Toc]    [Back]

       od - dump files in octal and other formats

SYNOPSIS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

       Write an unambiguous representation, octal bytes by default, of FILE to
       standard output.  With no FILE, or when FILE is -, read standard input.

       -A, --address-radix=RADIX
	      decide how file offsets are printed

       -j, --skip-bytes=BYTES
	      skip BYTES input bytes first on each file

       -N, --read-bytes=BYTES
	      limit dump to BYTES input bytes per file

       -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 pre-POSIX form

       --help display this help and exit

       --version
	      output version information and exit

   Pre-POSIX 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 maybe . for octal and b 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.  -s without a number implies 3.  -w without a number implies
       32.  By default, od uses -A o -t d2 -w 16.
