OD ST-UNIX User's Manual OD
COMMAND
od - octal, decimal, hex, ascii etc. dump
FORMAT
od [ -format ] [ file ] [ [+]offset[.][b] [label] ]
DESCRIPTION
_✓O_✓d displays _✓f_✓i_✓l_✓e, (standard input default), in one or more
dump formats specified by _✓f_✓o_✓r_✓m_✓a_✓t (default is -o).
The options for format are:
a Interpret bytes as characters and display them with
their ASCII names.
b Interpret bytes as unsigned octal.
c Interpret bytes as ASCII characters. Certain non-
graphic characters appear as C escapes: null=\0,
backspace=\b, formfeed=\f, newline=\n, return=\r,
tab=\t; others appear as 3-digit octal numbers.
d Interpret (short) words as unsigned decimal.
D Interpret long words as unsigned decimal.
e or F
Interpret double words as double precision floating
point.
f Interpret long words as single precision floating
point.
h or x
Interpret (short) words as unsigned hexadecimal.
H or X
Interpret long words as unsigned hexadecimal.
i Interpret (short) words as signed decimal.
l, I, or L
Interpret long words as signed decimal.
o or B
Interpret (short) words as unsigned octal.
O Interpret long words as unsigned octal.
v Show all data. By default, display lines that are
identical to the last line shown are not output, but
are indicated with an ``*'' in column 1.

OD ST-UNIX User's Manual OD
w_✓n Specifies the number of input bytes to be interpreted
and displayed on each output line. If w is not speci-
fied, 16 bytes are read for each display line. If _✓n is
not specified, it defaults to 32.
The _✓o_✓f_✓f_✓s_✓e_✓t 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 _✓o_✓f_✓f_✓s_✓e_✓t is inter-
preted in decimal. If _✓o_✓f_✓f_✓s_✓e_✓t 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 bytes. If the _✓f_✓i_✓l_✓e argument is omitted, an
_✓o_✓f_✓f_✓s_✓e_✓t argument must be preceded by ``+''.
The radix of the displayed address will be the same as the
radix of the _✓o_✓f_✓f_✓s_✓e_✓t, if specified; otherwise it will be
octal.
_✓L_✓a_✓b_✓e_✓l will be interpreted as a pseudo-address for the first
byte displayed. It will be shown in ``()'' following the
file offset.
