 In the UNIX class Public Directory on lab46 you will find a **dac0/** subdirectory. You can reach the directory by **cd /var/public/fall2023/unix/**. Once there use **ls** to check see if you can find it. Once there enter the dac0 directory and into your the directory with your username. From there you can **cp** the files, specifying the absolute path to your dac0 (assuming you already made a dac0 directory in where you store your projects) directory in your home directory like **~/src/fall2023/unix/dac0/**. Then head to that directory via the same absolute path that you specified and verify all of the files are there with **ls**. In the UNIX class Public Directory on lab46 you will find a **dac0/** subdirectory.

 +Once this is done use the stat "-c %s filename" command to see how big each file is, then rename them in order from smallest to largest with the letters of the alphabet, a being smallest, h being the largest.
