od − dump files in octal and other formats
od
[OPTION]... [FILE]...
od --traditional [FILE]
[[+]OFFSET [[+]LABEL]]
Write an
unambiguous representation, octal bytes by default, of FILE
to standard output. With no FILE, or when FILE is -, read
standard input.
−A,
−−address−radix=RADIX
decide how file offsets are printed
−j, −−skip−bytes=BYTES
skip BYTES input bytes first on each file
−N, −−read−bytes=BYTES
limit dump to BYTES input bytes per file
−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 pre-POSIX form
|
−−help |
display this help and exit |
−−version
output version information and exit
Pre-POSIX format specifications may be intermixed, they accumulate:
|
−a |
same as −t a, select named characters | ||
|
−b |
same as −t oC, select octal bytes | ||
|
−c |
same as −t c, select ASCII characters or backslash escapes | ||
|
−d |
same as −t u2, select unsigned decimal shorts | ||
|
−f |
same as −t fF, select floats | ||
|
−h |
same as −t x2, select hexadecimal shorts | ||
|
−i |
same as −t d2, select decimal shorts | ||
|
−l |
same as −t d4, select decimal longs | ||
|
−o |
same as −t o2, select octal shorts | ||
|
−x |
same as −t x2, select hexadecimal shorts |
For older syntax (second call format), OFFSET 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 maybe . for octal and b 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. −s without a number implies 3. −w without a number implies 32. By default, od uses −A o −t d2 −w 16.
