Moderator's Comments:
Mod Comment CODE tags inserted by moderator. Leaving out the CODE tags never makes clear what you are seeing on your terminal; it just hides where output might contain multiple adjacent spaces and/or tabs, hides line breaks or lack thereof, hides leading spaces and tabs on all lines, and converts tabs to spaces.


I believe I need a out come to look like this
Code:
:~> \. CS_STUDENTS
