If even, the output should read: Your number is even
If odd, the output should read: Your number is odd
Save the script exercise5.sh and upload it to this assignment for credit.
Commands you might want to use in your script:
echo
read
modulus mathematical command %
if-then-else conditional statement
( DO NOT MIX PYTHON WITH BASH)

Answer 1

The task is to create a Bash script named exercise5.sh that reads a user input number and uses a conditional statement to determine if it is even or odd, then echos the appropriate message.

Step-by-step explanation:

The task involves writing a script in Bash to determine if a user-input number is even or odd. Here is a step-by-step explanation on how you can create the script, named exercise5.sh:

• Open your text editor and start writing the script.
• Use the read command to take a number as user input.
• Utilize the modulus mathematical command % to find the remainder when the number is divided by 2.
• Apply the if-then-else conditional statement to check if the remainder is 0. If so, the number is even; otherwise, it is odd.
• Finally, echo the appropriate message based on the result.

Here is the Bash script you can save as exercise5.sh:

#!/bin/bash
read -p "Enter a number: " num
if (( num % 2 == 0 )); then
echo "Your number is even"
else
echo "Your number is odd"
fi

This script will display Your number is even if the input is an even number, or Your number is odd if the input is an odd number when you run it.
