Traditional 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 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.
