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
-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 hexadecimal;
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
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 prefix, it is multiplied by 512
with b suffix, by 1024 with k and by 1048576 with m. Adding a z suffix to
any type adds a display of printable characters to the end of each line
of output. --string without a number implies 3. --width without a number
implies 32. By default, od uses -A o -t d2 -w 16.
