3-Navigating the Filesystem
- Recap
    - Filesystem is a Tree Structure
    - / is the root
    - /Volumes/Name of disk
    - . = name of current folder
    - .. = name of enclosing folder
    - ~ = home folder = /Users/Username
- Moving Around the Filesystem
    - pwd
        - tells you the current working directory
        - if you just open a Terminal and type pwd, it should tell you
          that you are in your home folder
    - cd
        - change directory
        - 4 Uses
            - 1. cd (no arguments)
                - take me to my ~
            - 2. cd -
                - take me to where i was last
            - 3. cd /path or relative path
                - if /path, take me to this absolute path
                - if relative path, take me to this directory relative
                  to the one i am currently working in
                    - to go from ~ to your desktop, type either:
                    - cd ~/Desktop
                    - cd Desktop
            - 4. cd ..
                - take me to the enclosing folder
                - for relative paths, you can incorporate ..
                    - if you are in ~/Desktop, you can go to
                      ~/Documents by
                    - cd ../Documents
