如果第一个和第二个调用格式都适用，则如果最后一个操作数以“ + ”开头或（如果有2个操作数）一个数字，则采用第二种格式。一个OFFSET操作手段-J 偏移。LABEL是打印的第一个字节的伪地址，在转储进行时递增。对于OFFSET和LABEL，0x或0X前缀表示十六进制；后缀可以是“。” 八进制，b乘以512。
TYPE由以下一项或多项规范组成：
|
a
|

|
|
c
|
ASCII字符或反斜杠转义
|
|
d[SIZE]
|

|
|
o[SIZE]
|

|
|
u[SIZE]
|
无符号十进制，每个整数SIZE个字节

SIZE是一个数字。对于TYPE在d/o/u/x，SIZE也可以是C用于sizeof（char）的，S用于sizeof（短），I用于sizeof（int）的或L用于sizeof（长）。如果TYPE是f，则对于sizeof（float）而言，SIZE也可以是F，对于sizeof（double）来说可以是D，对于sizeof（long double）来说可以是L。
RADIX是d代表十进制，o代表八进制，x代表十六进制，n代表无。BYTES是带有0x或0X前缀的十六进制，并且可以具有乘数后缀：b 512，kB 1000，K 1024，MB 1000 * 1000，M 1024 * 1024，GB 1000 * 1000 * 1000，G 1024 * 1024 * 1024和对于T，P，E，Z，Y等等。向任何类型添加z后缀会在每行输出的末尾显示可打印的字符。选项-不带数字的字符串表示3; option --width不带数字表示32。默认情况下，od使用-A o -t oS -w16。

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, ignoring high-order bit
|
|
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 d/o/u/x, 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, and may have a multiplier suffix: b 512, kB 1000, K 1024, MB 1000*1000, M 1024*1024, GB 1000*1000*1000, G 1024*1024*1024, and so on for T, P, E, Z, Y. Adding a z suffix to any type displays printable characters at the end of each output line. Option --string without a number implies 3; option --width without a number implies 32. By default, od uses -A o -t oS -w16.
