Complete code of the program

read -p "Enter the value of n (number): " n
x=0
y=1
i=2
echo "Fibonacci Series up to $n terms is : "
echo "$x"
echo "$y"
while [ $i -lt $n ]
do
        i=`expr $i + 1`
        z=`expr $x + $y`
        echo "$z"
        x=$y
        y=$z
done

Interpreting the fibonacci.sh file and executing it in terminal

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