Name
       od - create file octal dump

Syntax
       od [options] [file] [offset] [label]

Description
       The  command displays file, or its standard input, in one or more dump formats as selected by the first argument.  If the first argument is
       missing, -o is the default.  Dumping continues until end-of-file.

Options
       -a[p|P] Interprets bytes as characters and display them with their ACSII names.	If the p character is given also,  then  bytes	with  even
	       parity are underlined.  The P character causes bytes with odd parity to be underlined.  Otherwise the parity bit is ignored.

       -b      Displays bytes as unsigned octal.

       -c      Displays  bytes	as ASCII characters.  Certain non-graphic characters appear as C escapes: null=, backspace=, formfeed=f, new-
	       line=
, return=
, tab=	; others appear as 3-digit octal numbers.  Bytes with the parity bit set are displayed in octal.

       -d      Displays short words as unsigned decimal.

       -f      Displays long words as floating point.

       -h      Displays short words as unsigned hexadecimal.

       -i      Displays short words as signed decimal.

       -l      Displays long words as signed decimal.

       -o      Displays short words as unsigned octal.

       -s[n]   Looks for strings of ASCII characters of n minimum length.  By default, the minimum length is 3 characters.

       -v      Displays all data and indicates lines identical to the last line shown with an * in column 1.

       -w[n]   Specifies the number of input bytes to be interpreted and displayed on each output line. If w is not specified, 16 bytes  are  read
	       for each display line.  If n is not specified, it defaults to 32.

       -x      Displays short words as hexadecimal.

       An upper case format character implies the long or double precision form of the object.

       The  offset  argument  specifies  the  byte  offset into the file where dumping is to commence.	By default this argument is interpreted in
       octal.  A different radix can be specified; If ``.'' is appended to the argument, then offset is interpreted in decimal.  If offset  begins
       with  ``x'' or ``0x'', it is interpreted in hexadecimal.  If ``b'' (``B'') is appended, the offset is interpreted as a block count, where a
       block is 512 (1024) bytes.  If the file argument is omitted, an offset argument must be preceded by ``+''.

       The radix of the displayed address is the same as the radix of the offset, if specified; otherwise it is octal.

       The label is interpreted as a pseudo-address for the first byte displayed.  It is shown	in  ``()''  following  the  file  offset.   It	is
       intended to be used with core images to indicate the real memory address.  The syntax for label is identical to that for offset.

Restrictions
       A file name argument can't start with ``+''.  A hexadecimal offset can't be a block count.  Only one file name argument can be given.

       It is an historical botch to require specification of object, radix, and sign representation in a single character argument.
