Write a bash script that prompts a user to enter either a U.S. zip code or a Canadian postal code. Your application should validate the input with a regular expression(s), and print out which type the code is, or that it doesn't match either. U.S. Postal Code form: 99999-9999 Canadian Postal Code form: A5B-7M4 Hint: it is quite easy to find a regular expression that does this, just google "u.s. canadian postal code regular expression")
