telephonefile_P2:

The pointy-haired manager's secretary, Pat, keeps a telephone directory for him. But Pat mixes up local phone numbers, long distance phone numbers, and even international numbers in it. Worse, Pat has no common method of entering numbers, some area codes are surrounded by ( ), some are not. Some numbers have a space between them, others a dash. The pointy-hair manager only wants to see the file with the names and their North American number plan numbers in it the familiar seven digit number. (Those are numbers that end with 3 numbers, a space or dash, and then 4 numbers). Work out a command structure that can be issued to the file telephonefile_P2, that returns the following:
