一、Linux账号空闲登出(Idel logout)

二、sudo命令使用

编辑/etc/sudoers文件，按照示例root的格式，添加相应账号

-u：后接欲切换的用户，若不加，则为root

[oracle@TaylonMeng ~]$ more /etc/shadow
/etc/shadow: Permission denied
[oracle@TaylonMeng ~]$ sudo -u root more /etc/shadow

#2) Think before you type.
#3) With great power comes great responsibility.
