清除討厭的linux系統郵件！

在操作Linux命令時，時常出現以下這樣一句話

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

這個是提示有最新的郵件，你可以使用mail命令閱讀

1 2 3 4 5 6 7

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

然後使用n 編號查看相應郵件，如查看編號爲4的郵件

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

& n 4 Message  4: From [email protected]  Tue Apr 10 20:22:07 2012 Return-Path: <[email protected]> X-Original-To: root@localhost Delivered-To: [email protected] Date: Tue, 10 Apr 2012 20:22:07 +0000 From: [email protected] To: [email protected] 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鍵退出mail系統

1 2 3 4

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

當然，裏邊都是一些無關緊要的郵件，我們也可以清空，清空很簡單，只需要進入/var/spool/mail就好

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

列出了所有用戶的郵件

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

刪除郵件，比如刪除root的郵件，只需要寫空就好，最好別刪除，否則容易出錯

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

這樣即可刪除煩人的郵件提示了，雖然執行echo ''>root命令會提示You have mail in /var/spool/mail/root但實際上郵件內容已經清空，當root文件發生改動，一律都提示You have mail in /var/spool/mail/root
