Linux系统邮件查看及清空

在操作Linux命令时，时常出现以下这样一句话

1	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

1 2 3 4 5 6 7

-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" >U  2 user@localhost.local  Tue Apr 10 20:15 183/7730  "[abrt] full crash report"  U  3 user@localhost.local  Tue Apr 10 20:20 183/7730  "[abrt] full crash report"  U  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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

& 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

1 2 3 4

& 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

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

列出了所有用户的邮件

1 2 3 4 5

total 14560 -rw-rw---- 1 li** mail     6774 May 18 17:17 lizhong8532 -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

1 2 3 4 5 6 7 8

-bash-4.1# echo ''>root You have mail in /var/spool/mail/root -bash-4.1# ll total 12 -rw-rw---- 1 li** mail 6774 May 18 17:17 lizhong8532 -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命令会提示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
