   wait

exit 0
==========================以上的参数需要很大cpu和内存、带宽才能操作,要不然你懂得
#!/bin/bash
#This is Mail sent a large number of intelligent bash script
#Write time 2013-8-4
#Author webjin
Max=500
for(( MID = 0 ;MID < $Max ; MID ++ ))
do

   echo  $((16#`dd if=/dev/urandom bs=1 count=4 2>/dev/null| od -A n -t x4|sed s/[^1-9a-fA-F]//g`)) >> ~/id.txt

done

for ID in `cat ~/id.txt`
do

   mail -s " ` < title.txt ` " $[email protected] < ~/content.txt
   wait
  done
[ -n " 'pgrep mail ' " ] && sleep 3m && > ~/id.txt;> /var/spool/mail/$SUER;
exit 0
=================以上脚本小内存的也可以操作，并且方便加入定时任务
#crontab -e
*/5 * * *  * /root/script_file_name  &

============================欢迎大家加入这个脚本编写当中大家进一步完善它

对了前提要装sendmail服务

我最近也在重写以前的一个用邮箱备份数据的shell，不过没有打算使用sendmail，而是直接使用/dev/tcp
