Finished Unix, File Permissions, Command Line lesson

This material seemed boring, at times, and that probably slowed me down. But it is probably important. It may have taken me longer than 4 hours to read this lesson and really if I want to finish all I want to finish, I should probably try to be faster in future studies. The good news is that I enjoyed and believe I understand the programming used in this lesson. That will hopefully make things faster and more fun!
