read -p "Subject 1: " s1
read -p "Subject 2: " s2
read -p "Subject 3: " s3
sum=`expr $s1 + $s2 + $s3`
echo "Sum of marks of 3 subjects is : "$sum
per=`expr $sum \* 10 / 9`
echo "Percentage: "$per
if [ $per -ge 60 ]
then
        echo "you got Distinction"
elif [ $per -ge 50 ]
then
        echo "you got First class"

fi

Then press ESC and then Enter :wq which will bring you out of the vim editor writing that code into your marksheet.sh file.

Now compile and run the created file.

tkanu025@hp:~/lab_solutions$ chmod +x marksheet.sh
tkanu025@hp:~/lab_solutions$ ./marksheet.sh
