UNIX for Dummies Questions & Answers

hey, have been set this question at school and cannot think for the life of me how to do this. Ive thought about setuid/setgid and things like that but cant make any snese of it. Can anyone help?


question reads:

You have a file which has the names, email addresses,
mobile numbers and sales records of a company's
employees. Using the UNIX access control model, explain
how you would only provide the names of employees to
team A, their names and sales records to team B and all
their details to team C.

thanks (i thnik firstly separate name, emails, sales records, mobile numbers into four separate files)
