记录一个shell基本脚本

有时候闲着没事干，总想找点什么打发时间，所以又折腾了一个shell脚本，没有具体要做的事情，无非有些好玩，有些作用

彩色时间，在shell里面显示一个绚丽的时间

动态时间，可以作为shell待机屏保，还能实时查看当前的时间，个人觉得有些小爱好的朋友可以玩玩，基于写vue脚本的时候启动控制台的特殊字体

 shell对话，制作一个选项供用户选择，以实现不同的目标，比如版本号选择

 密码设置，可以通过该对话框让用户设置某个程序的密码，功能与对话相似，支持限时输入

版本检测，可以使用该检测函数发散思维，检测你想检测的所有软件版本

 由于我的环境是centos 7 无法直接安装toilet，需要提前安装repo源，所以我把源下载到本地，从本地安装，省去后面自行查找的问题，我把这个源放在资源地址里面，大家自行下载
