Lesson 5: Moving Around with cd

So far we only looked (`pwd`, `ls`). Now we move. The command `cd` (change directory) takes you from folder to folder — like opening a door into another room.

cd is opening a door into another room. cd .. is stepping back out into the hallway.

cd: A command that moves you to another folder (change directory)
Parent directory (..): The folder that contains the current folder
Home directory (~): Your personal folder, where cd returns with no argument
