| [root@localhost Linux_Test]# od --help
用法：od [选项]... [文件]...
或：od [-abcdfilosx]... [文件] [[+]偏移量[.][b]]
或：od --traditional [选项]... [文件] [[+]偏移量[.][b] [+][标签][.][b]]
将指定文件以八进制形式(默认)转储到标准输出。如果指定了多于一个的文件
参数，程序会自动将输入的内容整合为列表并以同样的形式输出。
如果没有指定文件，或指定文件为"-"，程序从标准输入读取数据。
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.
Mandatory arguments to long options are mandatory for short options too.
-A, --address-radix=RADIX output format for file offsets; RADIX is one
of [doxn], for Decimal, Octal, Hex or None
-j, --skip-bytes=BYTES skip BYTES input bytes first
-N, --read-bytes=BYTES limit dump to BYTES input bytes
-S BYTES, --strings[=BYTES] output strings of at least BYTES graphic chars;
3 is implied when BYTES is not specified
-t, --format=TYPE select output format or formats
-v, --output-duplicates do not use * to mark line suppression
-w[BYTES], --width[=BYTES] output BYTES bytes per output line;
32 is implied when BYTES is not specified
--traditional accept arguments in third form above
--help 显示此帮助信息并退出
--version 显示版本信息并退出
Traditional format specifications may be intermixed; they accumulate:
-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 printable characters or backslash escapes
-d same as -t u2, select unsigned decimal 2-byte units
-f 即 -t fF，指定浮点数对照输出格式
-i 即 -t dl，指定十进制整数对照输出格式
-l 即 -t dL，指定十进制长整数对照输出格式
-o 即 -t o2，指定双字节单位八进制数的对照输出格式
-s 即 -t d2，指定双字节单位十进制数的对照输出格式
-x 即 -t x2，指定双字节单位十六进制数的对照输出格式
TYPE is made up of one or more of these specifications:
a named character, ignoring high-order bit
c printable character or backslash escape
d[尺寸] 有符号十进制数，每个整形数占指定尺寸的字节
f[尺寸] 浮点数，每个整形数占指定尺寸的字节
o[尺寸] 八进制数，每个整形数占指定尺寸的字节
u[尺寸] 无符号十进制数，每个整形数占指定尺寸的字节
x[尺寸] 十六进制数，每个整形数占指定尺寸的字节
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).
Adding a z suffix to any type displays printable characters at the end of
each output line.
BYTES is hex with 0x or 0X prefix, and may have a multiplier suffix:
b 512
KB 1000
K 1024
MB 1000*1000
M 1024*1024
and so on for G, T, P, E, Z, Y.
