1. Create a Unix command line that displays the information in phoneList.dat but with every 804 area code changed to 757.

Based on the sample phones.dat file, your output should be:

Edmonds Clarence (757)314-0090

Henry Henry (373)555-4444

Guilford Sharonda (414)315-8836

Koomson Isaac (757)259-3281

Lee Jacque (757)270-8238

Maye-Hobbs Jonathan (757)322-5062

Monk Monika (414)265-9623

Parker Deborah (906)280-7123

Boutros Ellen (414)555-2622

Powell Michael (757)260-1003

Note: don't actually change the contents of phones.dat. Just show to standard output what it would look like with the 804 area codes changed to 757.
