NAME
od - octal dump
SYNOPSIS
od [ -bcDdFfOoSsvXx ] [ file ] [ [ + ]offset[ . | b ] ]
DESCRIPTION
od displays file in one or more formats, as selected by the
first argument. If the first argument is missing, -o is
default. If no file is specified, the standard input is
used. For the purposes of this description, "word" refers
to a 16-bit unit, independent of the word size of the
machine; "long word" refers to a 32-bit unit, and "double
long word" refers to a 64-bit unit. The meanings of the
format options are:
-b Interpret bytes in octal.
-c Interpret bytes as single-byte characters. Certain
non-graphic characters appear as C-language escapes:
null=\0, backspace=\b, form-feed=\f, new-line=\n,
return=\r, tab=\t; others appear as 3-digit octal
numbers. For example:
echo "hello world" | od -c
0000000 h e l l o w o r l d
\n
0000014
-D Interpret long words in unsigned decimal.
-d Interpret words in unsigned decimal.
-F Interpret double long words in extended precision.
-f Interpret long words in floating point.
-O Interpret long words in unsigned octal.
-o Interpret words in octal.
-S Interpret long words in signed decimal.
-s Interpret words in signed decimal.
-v Show all data (verbose).
-X Interpret long words in hex.
-x Interpret words in hex.

OD(1) RISC/os Reference Manual OD(1)
offset specifies an offset from the beginning of file where
the display will begin. offset is normally interpreted as
octal bytes. If . is appended, offset is interpreted in
decimal. If b is appended, offset is interpreted in blocks
of 512 bytes. If file is omitted, offset must be preceded
by +.
The display continues until an end-of-file is reached.
INTERNATIONAL FUNCTIONALITY
od can process characters from supplementary code sets.
With the -c option, multibyte characters are treated as
non-graphic characters.
The value of the offset argument must be specified in bytes.
