运行sh程序的时候显示：

# ./convert_edition.sh
 bash: ./convert1.sh: /usr/bin/bash: bad interpreter: No such file or directory

这是文件编码格式问题，有时出现在windows环境写代码传到linux环境执行的时候。网上有很多种格式转换方式，比如用notepad++转换，使用python脚本转换等。

我们可以简单的安装 dos2unix来解决这个问题，

root@eve-ng:~# apt install dos2unix
Reading state information... Done

装完之后，执行

再运行sh脚本就OK了
