ping发现掉包报警的shell代码

#!/bin/bash
ping=`which ping`
date=`date +%y%m%d%h%m`
tail=`which tail`
log=./ping$date.log
hosts="selboo.com.cn 221.130.191.97"
count=200
for myhost in $hosts
do
count=$(ping -c $count $myhost | grep ‘loss' | awk -f',' '{ print $3 }' | awk -f “%” ‘{ print $1 }')
if [ $count -ge 10 ]; then
/bin/echo selboo | mutt -s "$myhost pingispacketloss>10% $date" [e-mail]
fi
done
exit 0

复制上以上内容为ping.sh加入crontab中让其10分钟跑一次，其中发邮件程序为mutt

以下是补充：

linux 的和solaris的居然不一样！
