Thanks for all your time and I will forever be greatful for your time.

FAIL_CODE=$(ssh $i "tail -2 /var/sam/log/br_log 2> /dev/null | grep -i 'Completed' | tail -1")
...
esace

I think is your problem...

Change to-
if $(ssh $i "tail -2 /var/sam/log/br_log 2> /dev/null | grep -q -i 'Completed'") ; then
COLOR="GREEN"
else
COLOR="RED"
fi

The if will test the status of the last command (grep in this case) and if Completed is found, then set COLOR to GREEN.

Hi Sanjay,

Since there is no fixed field for the STATUS, you may want to use this code. You can extend the if statement further if you have other STATUS values in addition to "successful" and "FAILED".

Take out the case statement and replace it with the following
....
ssh $i "tail -2 /var/sam/log/br_log " |grep "successful" > /dev/null 2>&1
if [ $? = 0 ]
then
COLOR="GREEN"
else
COLOR="RED
fi
...

Hi,

I've worked in a similar case but ussing a custom script file, my logic have been the following:

fbackup -0 -v -i / -e /tmp -f /dev/rmt/0m 2> /tmp/fbackup.log
STATUS=$?
case in $STATUS
0) Your successful procedure
;;
4) Your warning procedure
;;
*) Your fail procedure
;;
esac

The main advantage of redirect the log file (/tmp/fbackup.log), is that you can manipulate it to extract the warning messages and send them in the case of a status 4.
