[root@NGINX-APACHE-SVN pro]# file 交互式创建apache虚拟主机.txt
交互式创建apache虚拟主机.txt: Bourne-Again shell script text executable
#这是个shell肢本，但里面有中文，显示为乱码！

同样用iconv命令来除理，结果成功了！

[root@NGINX-APACHE-SVN pro]# iconv -f GBK -t UTF- 交互式创建apache虚拟主机.txt -o 交互式创建apache虚拟主机.txt 

如果去掉#!/bin/bash 再次查看：

[root@NGINX-APACHE-SVN pro]# file  交互式创建apache虚拟主机.txt
交互式创建apache虚拟主机.txt: ISO- text, with CRLF line terminators

所以这个乱码的问题，可以用上面的方法去解决！！
