Using greeting script with Dynamic Variables Greeting Script with Dynamic Variables

Write a Bash script that dynamically greets the user based on the current time and their username. The script should: $-$ Display $$Good morning, $[$username$]$ if the current hour is less than $12.-$ Display $$Good afternoon, $[$username$]$ if the current hour is between $12$ and $18.-$ Display $$Good evening, $[$username$]$ if the current hour is greater than $18.$

Hint: Use $$($date $+\%$H$)$ to get the current hour and $USER for the username. Commands like date in Unix or Linux systems are utility programs provided by the operating system to perform specific tasks from the command line or within scripts. The date command, specifically, is used to display or set the system$$s date and time. To find out more about the date command, type man date in your terminal. The manual page for date will explain how to format the output, set the system date, and more.

$USER is an environment variable representing the current logged$-$in user$$s name. You may refer back to Module $14$ for Environment Variables.

Expected Output:

niroshinie@MacBook$-$Pro$-17$ OtherResources $\%./$greeting$.$sh

Good morning, niroshinie.
