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, incremented when dump is progressing.  For OFFSET and LABEL, a 0x or 0X prefix indicates hexadec-
       imal; 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  pre-
       fix,  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.
