All right, guys, so before we dive into the setup, you may find that some of the things we are about
to do may venture into areas that you're unaware of when working with a computer.
Some of you may be more powerful users and some of you may just be new to all of this.
And we want to give you a solid foundation on which you can build.
So we want to show you things that you may not have seen before.
And depending on what type of system you run, you may find that there are just certain features that
have eluded you throughout your usage.
You may be a powerful Excel user, maybe a powerful PowerPoint user, but you're just certain things
to a computer that you haven't been in touch with yet.
So when we're doing school in Posterous and over here, you can see I'm on my Mac.
Well, certain systems use Unix or Linux or Mac.
These are types of operating systems and Mac is very close to Linux.
And then you have people that use this completely different paradigm.
The majority of you may be Windows users, but what all of these computers have in common is that they
use bits and bytes.
And so there are ways in which you can communicate with your computer that you may not be used to.
And before we get into setting up all of this that you see here, well, first we have to get into the
setup of our databases.
And postcrisis particularly is an interesting technology that you're learning, because although you
have all of these tools to show you things visually, a lot of people like to run PostgreSQL in the
command line.
Now, you may be frowning and saying, we command what's the command line?
Well, this tool may have eluded you throughout your PC usage or your Mac usage or your Linux usage.
Not so much for the Linux users.
If you're in the Linux space, if you're using a Boodhoo, you've probably found your way around the
terminal.
But basically there is this thing called a terminal.
And on windows, it'll be called the command line.
And so what that looks like is the following.
It's a textual interface.
So when you open it up.
It may look like this, it may look a bit smaller, it may open up in a frame about this size, but
depending on how you use it and depending on if you're familiar with it, it'll just open up in a basic
way.
And what it allows you to do is it allows you to interface with your computer from a text perspective.
Now, there are multiple commands that you can run in command line and will reference some material
that will help you supercharge your adventure down the command line route.
But some of the most important ones that we'll be using are L's, which is list directory.
You can also do a.
Which will show you the directory and the hidden files files that you normally can see when you browse
your system, there is change directory, which is KDDI change directory.
And if you see if we go into databases, well, if we do list there now, we have a completely different
file structure.
And so this mimics us going into documents and seeing what's here.
As you can see here, we're seeing databases and databases, dot, zip, and then when we're inside
of databases, we can see France employee.
But we see these files here, icon, questionmark dStore files that we can't see when we're in our finder.
And so that's what's cool about using command line.
It doesn't only look like a matrix hacking sequence, it's actually very functional when you start using
it, when you're programming and doing a school and doing other things.
And when we pop over into windows, you can equally use the same in command line where you do else.
Well, that doesn't seem to work.
Well, how do we do that in windows?
Well, in Windows, the command is actually there, and that'll show you the directory, dear, and
to change directory, it's the same thing.
So we can do desktop.
And then if we do, Daryn, here you can see what all is in the desktop.
So you can see over here, we have back up that will right over here.
And then we have two directories.
And one file.
All right, so with this, you have the power as a user to interface with your computer in a different
way.
And again, we'll be linking materials to push you along a journey to use command prompt wisely and
successfully.
But with this introduction, you have a solid foundation to know what we're talking about.
When we start doing things like importing our databases into PostgreSQL and other things that we can
do along the line, we will also include a section on specifically interfacing with Posterous in command
line when we go into talks about how to maintain your database.
So stay tuned for all of those.
