od
utility is a filter which displays each specified
file, or the standard input if no
file arguments are specified, in a user specified
format.
The options are as follows:
-A
based
’,
‘o
’,
‘x
’ or
‘n
’, which specify decimal, octal,
hexadecimal addresses or no address, respectively.-a

skip0x
or 0X
,
skip is interpreted as a hexadecimal number;
otherwise, with a leading 0
,
skip is interpreted as an octal number. Appending
the character b
, k
, or
m
to skip causes it to be
interpreted as a multiple of 512
,
1024
, or 1048576
,
respectively.-L

type_stringa
selects US-ASCII output, with
control characters replaced with their names instead of as C escape
sequences. See also the _u
conversion provided
by hexdump(1).
c
selects a standard character based
conversion. See also the _c
conversion provided
by hexdump(1).
f
selects the floating point output
format. This type character can be optionally followed by the characters
4
or F
to specify four
byte floating point output, or 8
or
L
to specify eight byte floating point output.
The default output format is eight byte floats. See also the
e
conversion provided by
hexdump(1).
d
, o
,
u
, or x
select decimal,
octal, unsigned decimal, or hex output respectively. These types can
optionally be followed by C
to specify
char-sized output, S
to
specify short-sized output, I
to specify int-sized output, L
to specify long-sized output,
1
to specify one-byte output,
2
to specify two-byte output,
4
to specify four-byte output, or
8
to specify eight-byte output. The default
output format is in four-byte quantities. See also the
d
, o
,
u
, and x
conversions
provided by
hexdump(1).
-v
-v
option causes od
to
display all input data. Without the -v
option, any
number of groups of output lines, which would be identical to the
immediately preceding group of output lines (except for the input
offsets), are replaced with a line comprised of a single asterisk
(‘*’).-X
-H
.-x
-h
.For each input file, od
sequentially
copies the input to standard output, transforming the data according to the
options given. If no options are specified, the default display is
equivalent to specifying the -o
option.
od
utility exits 0 on success,
and >0 if an error occurs.
od
command appeared in
Version 1 AT&T UNIX.
This man page was initially written in February 2001 by Andrew
Brown, shortly after he augmented the deprecated od
syntax to include things he felt had been missing for a long time.
