User Commands OD(1)
NAME
od - dump files in octal and other formats
SYNOPSIS
od [OPTION]... [FILE]...
od [-abcdfilosx]... [FILE] []OFSET[.][b]
od --traditional [OPTION]... [FILE] []OFSET[.][b]
[][LABEL][.][b]
DESCRIPTION
Write an unambiguous representation, octal bytes by default,
of FILE to standard output. With more than one FILE argu-
ment, 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 accu-
mulate:
-a same as -t a, select named characters, ignoring

high-order bit
-b same as -t o1, select octal bytes
-c same as -t c, select ASCI 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 for-
mat is assumed if the last operand begins with ] or (if
there are 2 operands) a digit. An OFSET operand means -j
OFSET. LABEL is the pseudo-address at first byte printed,
incremented when dump is progressing. For OFSET 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, ignoring high-order bit
c ASCI 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
-w16.
