Sounds like your friend is trying to teach you with "Hard love"
To make your terminals show color, you simply need to call ls with --color on the end, so open up your terminal and type:
And see all the colors come to life. Now everytime you ls do you really wanna type --color? Nah. So you open up a file in your home directory called .bashrc If one doesn't already exist, go ahead and create a new file, be sure it's in your current users home directory, so if you are logged in as masterc it's probably:

alias ls='ls --color=auto'
Save and exit, and now type:
And try using ls. The colors should be radiating out at you
