You should add a "whoami" command because thats the basic unix command to determine who the user is. Then you can put some information about yourself there. Als

You should add a "whoami" command because thats the basic unix command to determine who the user is. Then you can put some information about yourself there. Also, instead of having to type "help" to get the available commands you should print those out whenever you encounter an unknown command (since there are so few commands anyways). Good job though, it looks good!
