Hi
i have written 1 bash script but it is not working in cron job
the script is for checking the status of internet connection from two diff isp
using ping command
#!/bin/bash
for file in `cat ipaddress`
do
ipAdd=`echo $file | awk -F, '{print $1}'`
curstate=0
pstate=0
case "$ipAdd" in
1.1.1.1) prevstate="./mtnl.txt"
echo "IPADDRESS = $prevstate"
msg="./isp1_report.txt" ;;
2.2.2.2) prevstate="./netmagic.txt"
echo "IPADDRESS = $prevstate"
msg="./isp2_report.txt";;
esac
curstate=`/bin/ping -c 1 $ipAdd | grep "100% packet loss" | wc -l`
echo "current state= $curstate"
for pstate in `cat $prevstate`
do
echo "previous state==$pstate"
done
if [ $curstate -ne $pstate ] ; then
echo "status changed" ;
if [ $curstate -ne 0 ] ; then
echo "Time: `date` $ipAdd network failed" >> $msg ;
else
echo "Time: `date` $ipAdd network up" >> $msg ;
fi echo $curstate > $prevstate
echo `cat $prevstate`
else
echo "status remains the same as of previous" ;
fi
echo " "
done
crontab -l gives o/p
