mgmt-eth0(1) 10.7.225.5/24 mgmt Ethernet Up

lo1(1) 127.0.0.1/8 mgmt Loopback Up

i need to check the status column value whether it is Up. if its not it has to be logged in a separate file.

thanks
Code:
for line in `cat $file`
do
statusfield=`echo $line | tr -s " " | cut -d " " -f5`
if [ $statusfield = "up" ]
then
echo " system is up"
else

fi
done
