CIS 345 Homework 2 Write a bash script called greeting that will print out Good morning username in the morning, "Good afternoon username" between 12:00 and 5:59, and "Good evening username after 6:00. Substitute the user's real first name for username. The first letter of the user's name should be capitalized. Then it should report the user's last time of login and some statistics about your system. Report a total of how many users are logged in then display the user name, real name, and login time in columns with each listed only once. 5 points Write an interactive script to add a person's personal information to your customers and contacts file. Your file should not have duplicate entries in it. 5 points Write an interactive script to remove an entry from your customers and contacts file. Incorporate appropriate error checking in this and all the other scripts. 5 points Write a script to look up someone in your customers and contacts file.

Private information should not be returned. 10 points Write a bash script that takes an integer passed as a command line argument and outputs the equivalent in Roman Numerals. The rules are: 1-1 V-5 X-10 L-50 C-100 D-500 M-1000 There will be no more than three consecutive occurrences of the same letter. I can be placed before V and X indicating it is subtracted such as in IV =4 and IX = 9. Likewise X can be placed before L and C and can be placed before D and M.
