Navigating the file system

###pwd - print working directory, prints the directory you're currently in

###cd - change directory, or navigate to another "folder"

cd ~          # navigate to the home directory, which is the same as your user directory
cd jazzyfresh-cmsi281              # cd into the jazzyfresh-cmsi281 repo

###ls - list the contents of a directory

ls ~        # show the contents of the home directory, which is the same as your user directory
ls jazzyfresh-cmsi281                   # show the contents of the directory jazzyfresh-cmsi281
ls           # show the contents of the current working directory
ls -l        # show the contents of the current working direcotry in list format
ls -a        # show all the contents of the current working directory, even secret files that begin with a .
ls -la       # show all the contents of the current working directory, even secret files that begin with a .
             # AND show it in list format, because you can combine the "flags" or option parameters after one dash
