Write a Unix/Linux script file called q47 that displays the content of your current directory on the screen using the pipe command in order to show one screen at a time; then display the list of users who are currently logged into the system and send the output to a file called whois.out. When running your script, your program should prompt you to select a specific person logged on the system. (Use the shell variable concept to search for selecting a specific user from the list of users displayed on the screen).
