今天弄服务器的时候无意间用到此脚本，觉得当时写的虽然不咋样，但还是有点借鉴意义，就拿出来给大家看看。希望大家喜欢
先看看演示视频

OK然后我们来看看脚本的实现过程，时间有点久了当时的想法可能现在有点想不起来了，解释的不对的地方望见谅
脚本分为7个部分，这里我只做简单的解释
第一部分
脚本开始就利用awk提取日志中的用户名字段保存到tmp目录下的ftplog-userlist.txt文件中，方便后面查询
然后开始信息的展示，提供选择功能通过read函数读取用户的选择
第二部分 Show ftp Database
>通过 sed读取用户名
>通过sed读取用户总数
第三部分Ftp-log-Manager
>通过 cat读取ftplog-userlist.txt列表展示日志列表
>通过 cat读取ftplog-userlist.txt日志总数并展示,如果为0则打印Today, no one has logged an FTP server
>如果按3则通过read读取用户输入的用户名然后通过awk切割日志并展示
第四部分Add ftp Users
>通过 read读取用户输入，然后写文件，最后重启服务
第五部分Del ftp Users
>通过 read读取用户输入，然后写文件，最后重启服务
> rm 删除用户目录和配置信息
第六部分Chanage FTP user password
>通过 read读取用户输入,然后stty $(cat /root/.stty)隐藏用户输入，然后通过sed 替换配置文件
>最后dbload重载虚拟用户数据库,重启服务
第七部分EXIT
> 删除/tmp/ftplog-userlist.txt并退出脚本
脚本代码：
