users.rb

#In my program, I can create a simulated user session.
#The operator begins in a looped Shell class to perform commands like choosing a user (the select method below).

#Choosing a user begins a looped User class instance and assigns it to a @session variable that exists within a Shell class.
#The operator gains add, delete powers until he chooses to again start another new instance of Shell.

#I lose the ability to maintain a single Shell and dedicated users, like an @Joe = User.new("joe").
#When you switch from Joe to Bob, you begin each user anew. Same with the Shell.
#The only way a user is defined is by his associated files (I link the name "Joe" to a joe.file).
#How do you typically handle users? Is my approach off the deep end?

#I call a few outside methods here within the select method
#this method:
#prints lines in file, @userlist, that contains existing usernames (bob, joe, etc.; 1 per line)
#asks person to select existing user
#if selection matches existing user, begins a session
