Question

1. Write a shell code that prints the integers from 80-90

2. Write a shell code that prints the sum of odd integers that are inputted by the user

3. Write a shell code that reads a set of integers {125, 0, 122, 129, 0, 117} and prints {125, 122, 129, 117}

Programming Language: Linux

Answer 1

1. Below is shell code that prints the integers from 80-90:

#Method 1
seq 80 90

#Method 2
for ((a=80; a <= 90 ; a++))
do
   echo $a
done

Output:

2. Below is a shell code that prints the sum of odd integers that are inputted by the user.

first_num=0
second_num=0

#Read first odd number:
read -p "Enter the first odd number --> " first_num

#Read second odd number:
read -p "Enter the second number -> " second_num

echo "Sum is: = $((first_num + second_num))"

Output:

3. Below is a shell code that reads a set of integers {125, 0, 122, 129, 0, 117} and prints {125, 122, 129, 117}

#Reads a set of integers
read -a arr

#Print integers except 0 from list
for elem in ${arr[@]}
do 
    if (( elem != 0 ))
    then
            echo -n $elem "" 
    fi
done

Output:
