 \subsection*{Advanced Unix Tools}
-Most Unix implementations include a large number of powerful tools and utilities. (Unix has been in development for more than 50 years!). We were only able to scratch the surface in our class time. It will take time to become comfortable with Unix, but as you struggle, you will find yourself learning just by looking at \texttt{man} files and finding solutions on the internet. For this Extra Practice, you will explore several more advanced Unix functions. You can use any resource available to you--classmates, the internet, and Dr. Johnson. Ask all the questions you want, just make sure you do the work and you learn!
