linux网络状态检测脚本

我是一个新手，想做linux网络检查脚本，查询资料之后，写了如下脚本，可是没有结果，请大侠帮助！！！！
在cd /opt下建立脚本state.txt 、checkserverstat两个脚本
state.txt脚本：
#/bin/bash
echo "Daily test mail" >state.txt
mail -s Server_State [email=abc@md1.21.co.jp<state.txt]abc@md1.21.co.jp<state.txt[/email]
rm -df ./state.txt
checkserverstat 脚本
echo "huaide">state.ext
ping -c 192.168.2.252>>state.txt
mail -s Server_State [email=qinweibo@kelti.com.cn<state.txt]qinweibo@kelti.com.cn<state.txt[/email]
rm -df ./state.txt
crontab内容：
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
HOME=/
# run-parts
01 * * * * root run-parts /etc/cron.hourly
02 4 * * * root run-parts /etc/cron.daily
22 4 * * 0 root run-parts /etc/cron.weekly
42 4 1 * * root run-parts /etc/cron.monthly
*/1 * * * * sh /opt/checkserverstat
*/1 * * * * /root/checknkmail &
此为原帖：
1,通过定时收发email检测网络连通性
#/bin/bash
echo "Daily test mail" > state.txt
mail -s Server_State abc@md1.21.co.jp < state.txt
rm -df ./state.txt
~
crontab -e
增加如下任务
10 07 * * * /root/checkNKmail &
分时日月周

2,定时检测网络状态通过email发送
checkserverstat脚本内容：
#/bin/bash
echo "HZtelecomDNS" > state.txt
ping -c 5 202.101.172.35 >> state.txt
echo "
bJU" >> state.txt
ping -c 5 10.X.X.X >> state.txt
echo "ADSL Gateway" >>state.txt
mail -s Server_State admin@abc.com <state.txt
rm -df ./state.txt
~

crontab中增加任务
corntab -e
10 16 * * * /root/CheckWeatherState &
10 09 * * * /root/checkserverstate &
10 13 * * * /root/checkserverstate &
10 17 * * * /root/checkserverstate &

呵呵！！！帮你解决下吧
实在不想看你的脚本，看得我头晕，记得以后是熟悉shell scripts了回来看看现在的脚本体会下我的感受
cat /home/chk.sh
#!/bin/sh
if ! ping -c 5 192.168.2.252 > /dev/null 2>&1
then
echo "no ping" | mail -s "alarm" yourmailaddress
fi

*/5 * * * * root /home/chk.sh
