shell 发邮件命令之 mail

<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">目前最常用的就是mail命令了。 </span>

(sudo apt-get install mailutils)

也可手动下载安装：  http://mailutils.org/download.html 

1. 简单一行命令实现发送邮件
   echo 'content test' | mail -s "title test" -t  [email protected],[email protected],[email protected]    -a From:[email protected] 
   
2. 内容由文件导入
   mail -s "sh mail test"  < file1.txt
   
3. 带上附件
    (uuencode file1.txt file1.txt; uuencode file2.txt file2.txt) | mail -s "title test" -t  [email protected] 
   
   1. 内容 + 附件
      (echo '1111111'; uuencode file1.txt file1.txt; uuencode file2.txt file2.txt) | mail -s "title test" -t  [email protected] 
      
   2. 多个内容 +多个 附件
      (echo '1111111'; echo '22222222'; uuencode file1.txt file1.txt; uuencode file2.txt file2.txt) | mail -s "title test" -t  [email protected]

Cent OS 系统上： 

1. 下载安装mailutils
   wget ftp://ftp.gnu.org/gnu/mailutils/mailutils-2.2.tar.gz
   解压进入
   ./configure
   make && make install
2. yum install -y sendmail
3. yum install sharutils   # 使用带附件功能
   
4. service sendmail start 
5. 查看sendmail启动没：   ps aux |grep sendmail
6. 测试：    echo 'content test' | mail -s "title test"  -t [email protected]
7. 此时发觉只能给公司内部发邮件， 如果需要还能给外面的邮箱（比如我的qq邮箱）发邮件则还需要
   vi  /etc/mail/sendmail.mc
   找到包含Addr的这一行：    
   DAEMON_OPTIONS(`Family=inet,  Name=MTA-v4, Port=smtp, Addr=127.0.0.1')dnl
   修改Addr=0.0.0.0  ，表明可以连接到任何服务器
   
8. End

(data00和data03上已安装上)
