在操作Linux命令时，时常出现以下这样一句话

> You have mail in /var/spool/mail/root

这个是提示有最新的邮件，你可以使用mail命令阅读

-bash-4.1# mail 
    Heirloom Mail version 12.4 7/29/08.  Type ? for help.
    "/var/spool/mail/root": 383 messages 381 unread
        1 user@localhost.local  Tue Apr 10 20:09 183/7743  "[abrt] full crash report"
        2 user@localhost.local  Tue Apr 10 20:15 183/7730  "[abrt] full crash report"
        3 user@localhost.local  Tue Apr 10 20:20 183/7730  "[abrt] full crash report"
        4 user@localhost.local  Tue Apr 10 20:22 183/7730  "[abrt] full crash report"

然后使用`n 编号`查看相应邮件，如查看编号为4的邮件

& n 4
    Message  4:
    From user@localhost.localdomain  Tue Apr 10 20:22:07 2012
    Return-Path: <user@localhost.localdomain>
    X-Original-To: root@localhost
    Delivered-To: root@localhost.localdomain
    Date: Tue, 10 Apr 2012 20:22:07 +0000
    From: user@localhost.localdomain
    To: root@localhost.localdomain
    Subject: [abrt] full crash report
    User-Agent: Heirloom mailx 12.4 7/29/08
    Content-Type: text/plain; charset=us-ascii
    Status: RO
     
    Duplicate check

使用`q`键退出mail系统

& q
    Held 384 messages in /var/spool/mail/root
    You have mail in /var/spool/mail/root
    -bash-4.1#

当然，里边都是一些无关紧要的邮件，我们也可以清空，清空很简单，只需要进入`/var/spool/mail`就好

-bash-4.1# cd /var/spool/mail/

列出了所有用户的邮件

total 14560
    -rw-rw---- 1 ni** mail     6774 May 18 17:17 nicholas
    -rw-rw---- 1 mysql       mail        0 Apr 23 16:58 mysql
    -rw------- 1 root        mail 14880366 Jul 26 13:50 root
    -rw-rw---- 1 www         mail        0 Apr 23 18:23 www

删除邮件，比如删除root的邮件，只需要写空就好，最好别删除，否则容易出错

-bash-4.1# echo ''>root 
    You have mail in /var/spool/mail/root
    -bash-4.1# ll
    total 12
    -rw-rw---- 1 ni** mail 6774 May 18 17:17 nicholas
    -rw-rw---- 1 mysql       mail    0 Apr 23 16:58 mysql
    -rw------- 1 root        mail    0 Jul 26 13:54 root
    -rw-rw---- 1 www         mail    0 Apr 23 18:23 www

这样即可删除烦人的邮件提示了，虽然执行

echo ''>root

会提示

> You have mail in /var/spool/mail/root

但实际上邮件内容已经清空，当root文件发生改动，一律都提示`You have mail in /var/spool/mail/root`
