Write a complete bash script that asks for a user name and uses the read
command to accept the user name. (Use usernames C2456001 through
c2456030 to test.) The script reports if the user is logged in. Use the who
command to obtain a list of users logged in then use grep in an if then else
statement to match on the user name. Output whether that user is either
logged in or not logged in. (Usage: loggedIn.sh)
