QT实现终端交互（Windows和Linux通用）

先看下效果，Windows下和Linux下都可以直接交互，输入命令直接回车即可！注意，Linux下需要先设置正确的密码才可以执行sudo命令！使用了多线程执行，所以执行命令时界面不卡顿！实时回显！Linux下：同一套代码，直接执行即可！声明代码供参考：//author：autumoon//联系QQ：4589968//日期：2020-11-30#ifndef TERMINALINTERACTIVE_

注意，Linux下需要先设置正确的密码才可以执行sudo命令！

使用了多线程执行，所以执行命令时界面不卡顿！实时回显！

Linux下：

同一套代码，直接执行即可！
