When you open the terminal or GitBash, you'll
see something that looks a lot like this.
So this is basically application where you mostly see blank space.
And so what will see is what's called the prompt.
Which is your username.
Here in this case it's Sean followed by [INAUDIBLE].
And then so when you open this up, when you open
up the command line interface, you start in your home directory.
An important term that we'll be using a lot is called your working directory.
So that's whatever directory you're in at the moment.
So when you open you're command line
interface, you're working directory is your home directory.
If you move into a sub directory called
music, then your working directory will be music.
[SOUND] So another thing to keep in mind is the
path, so, people think about the path in the directory structure.
And so we'll be moving around along the path.
And so, suppose that you're down here, you're down
in your home directory which is signified by the tilde.
And so you might want to know what are the
directors that are, directories that are up from your home directory.
So the first directory that's up is the users directory.
And then the next directory up is the root directory.
So you can imagine the path is the set of directories you
have to follow in order to get back up to the root directory.
