Create a file called datafile if it has not been provided for you on the CD. It will consist of colon-separated fields:
First and last name
Phone number
Address (street, city, state, and ZIP)
Birth date (04/12/66)
Salary
Put ten entries in your file. Write a script called lookup that will do the following:
Welcome the user.
Print the names and phone numbers for all the users in datafile.
Print the number of lines in datafile.
Tell the user good-bye.
