shell: 如何设置 Linux 上 SSH 登录的 Email 提醒

你也可以选择性地让警告只对 root 用户生效：

1. [ root@vps ~]# vi . bashrc

将下面的内容添加到/root/.bashrc的尾部：

1. echo ‘ALERT – Root Shell Access (vps.ehowstuff.com) on:’ `date` `who` | mail – s “Alert: Root Access from `who | cut -d'(‘ -f2 | cut -d’)’ -f1`>” recipient@gmail . com

整个配置文件样例：

1. # .bashrc
2. # User specific aliases and functions
3. alias rm = ‘rm -i’
4. alias cp = ‘cp -i’
5. alias mv = ‘mv -i’
6. # Source global definitions
7. if [ – f / etc / bashrc ]; then
8. . / etc / bashrc
9. fi
10. echo ‘ALERT – Root Shell Access (vps.ehowstuff.com) on:’ `date` `who` | mail – s “Alert: Root Access from `who | cut -d'(‘ -f2 | cut -d’)’ -f1`>” recipient@gmail . com
