Linux登录提示信息动态显示

2023-10-10更新：用tput sgr0进行属性还原时，在web页面输出会显示出一个(B符号，如下：参考https://github.com/rburns/ansi-to-html/issues/25 解决方法是，增加一个变量：TERM=ansi 整体脚本如下：

#!/usr/bin/env bash

# function: show dynamic information after login server

# Change TERM value that is 'xterm' because it leads to extra '(B' chars after sgr0
