## $#是获取参数个数的意思
## -gt是大于的意思
## 所以这里是判断只有传入有参数时是才做while循环。
## 在 shell 中我们会见到 $0、$1、$2这样的符号，这是什么意思呢? 简单来说
## $0 就是你写的shell脚本本身的名字，
## $1 是你给你写的shell脚本传的第一个参数，
## $2 是你给你写的shell脚本传的第二个参数

## IFS= read -r line 命令含义
## 设置read命令读取buffer过程中的域分隔符设置为空字符（IFS=），并在不转义转义字符的前提下读取一行文本buffer（read -r）给变量line
## -z 判断 变量的值是否为空,
## - 变量的值为空，返回0，为true;
## - 变量的值非空，返回1，为false;
## /dev/null ：代表空设备文件
## > ：代表重定向到哪里
## 1 ：表示stdout标准输出，系统默认值是1,所以">/dev/null"等同于"1>/dev/null"
## 2 ：表示stderr标准错误
## & ：表示等同于的意思，2>&1，表示2的输出重定向等同于1
## 1 > /dev/null 2>&1 语句含义：
## 1 > /dev/null ： 首先表示标准输出重定向到空设备文件，也就是不输出任何信息到终端，说白了就是不显示任何信息。
## 2>&1 ：接着，标准错误输出重定向（等同于）标准输出，因为之前标准输出已经重定向到了空设备文件，所以标准错误输出也重定向到空设备文件。
