centos 7 要想title正常，需修改~/.bashrc

在~/.bashrc 中加入unset PROMPT_COMMAND

为此我还做了一个gif动画：

避免screen在vim,less等程序退出后不清屏

加上altscreen on选项

设置别名

alias scr='screen'

如果提示要密码

如果screen中的进程在消耗CPU，htop就会显示SCREEN进程占用CPU

[root@screen-4.5.0]$ cat ~/.screenrc

hardstatus onhardstatus alwayslastlinehardstatus string "%{.bW}%-w%{.rW}%n %t%{-}%+w %=%{..G} %H %{..Y} %m/%d %C%a "

$HOME/.screenrc如果不生效，可能需要给screen 加-a参数

用make install时，好像etc目录要手动复制？？

注意源码编译时，make install之后的提示，要求要手工将screencap,etcscreenrc复制到相关目录。碰到问题时，不要忽略这一点

从此妈妈再也不担心我突然断线工作丢失了……
