ubuntu默认安装md5sum

使用方法：md5sum 文件名

用法：md5sum [选项]... [文件]...

显示或检查 MD5(128-bit) 校验和。

若没有文件选项，或者文件处为"-"，则从标准输入读取。

-b, --binary 以二进制模式读取

-c, --check read MD5 sums from the FILEs and check them

-t, --text read in text mode (default)

The following three options are useful only when verifying checksums:

--quiet don't print OK for each successfully verified file

--status don't output anything, status code shows success

-w, --warn warn about improperly formatted checksum lines

--help 显示此帮助信息并退出

--version 输出版本信息并退出

The sums are computed as described in RFC 1321. When checking, the input

should be a former output of this program. The default mode is to print

a line with checksum, a character indicating type (`*' for binary, ` ' for

text), and name for each FILE.
