GTU OS Program - 3
3. Write a shell script to generate marksheet of a student. Take 3 subjects, calculate and display total marks, percentage and Class obtained by the student.
Make a file called marksheet.sh using vim. If you want a full guide to vim than you can check this post.
tkanu025@hp:~/lab_solutions$ vim marksheet.sh
When you will hit enter than it will open a window like the one below. This is
an editor and Here you can write your code.
Press i to enter into the insert mode
Write full code there like this
echo "Enter marks(out of 30) of "
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"
elif [ $per -ge 40 ]
then
echo "You got second class"
else
echo "sorry you failed! better luck next time"
fi
Then press ESC and then Enter :wq which will bring you out of the vim editor writing that code into your marksheet.sh file.
Now compile and run the created file.
tkanu025@hp:~/lab_solutions$ chmod +x marksheet.sh tkanu025@hp:~/lab_solutions$ ./marksheet.sh
