Mac上的mail

对于一些命令的操作，会有You have new mail.的一些操作，我遇到这些情况都是一些报错的情况出现。
那么怎么来进行管理这些所谓的mail呢。

在命令行中输入mail直接可以显示出来所有的mail：

yangchuang@yangdeMacBook-Pro-2 mail % mail
Mail version 8.1 6/6/93.  Type ? for help.
"/var/mail/yangchuang": 8 messages 8 new
>N  1 yangchuang@yangdeMac  Tue Mar 31 10:00  19/828   "Cron <yangchuang@yang"
 N  2 yangchuang@yangdeMac  Tue Mar 31 14:00  22/1039  "Cron <yangchuang@yang"
 N  3 yangchuang@yangdembp  Tue Mar 31 18:00  66/4620  "Cron <yangchuang@yang"
 N  4 yangchuang@yangdeMac  Thu Apr  2 10:00  18/962   "Cron <yangchuang@yang"
 N  5 yangchuang@yangdembp  Thu Apr  2 14:30  18/940   "Cron <yangchuang@yang"
 N  6 yangchuang@yangdeMac  Thu Apr  2 18:00  18/963   "Cron <yangchuang@yang"
 N  7 yangchuang@yangdeMac  Fri Apr  3 18:00  18/963   "Cron <yangchuang@yang"
 N  8 yangchuang@yangdeMac  Sat Apr  4 10:00  18/962   "Cron <yangchuang@yang"

每个邮件的第二行是标号，可以根据这个进行删除

查看邮件详情

直接输入前边的输入即可

删除邮件

• d 1　　删除标号为1的邮件；
• d 2-4　　删除标号2到4的邮件；

退出的时候需要注意，一定要用 q 命令来保存之前的操作。

q
退出mail命令平台,保存之前的操作，比如删除已用d删除的邮件，已阅读邮件会转存到当前用户家目录下的mbox文件中。如果在mbox中删除文件才会彻底删除。

x
退出mail命令平台，并不保存之前的操作，比如删除邮件
