00:00:07,590 --> 00:00:10,830

What is everybody this is Jason with does soapstar come.



2

00:00:10,840 --> 00:00:16,980

And in this video we are going to cover some basics of navigating using the terminal.



3

00:00:16,980 --> 00:00:23,150

So we're going to be covering how to change directories going back and forth between them and also how



4

00:00:23,150 --> 00:00:27,580

a list all items so we can see what's inside these directories.



5

00:00:27,770 --> 00:00:32,970

Now the first thing that we want to do is open up our terminal or our command line.



6

00:00:33,210 --> 00:00:34,540

So I'm on Mac.



7

00:00:34,650 --> 00:00:36,380

You can do this one of two ways.



8

00:00:36,390 --> 00:00:43,230

You can either hit command space and just type in and do a spotlight search for the terminal or we could



9

00:00:43,230 --> 00:00:50,820

simply do this through the finder and to do that just go to your applications come down to the bottom



10

00:00:50,820 --> 00:00:57,600

you'll see a folder called utilities and then just find the Terminal application.



11

00:00:57,660 --> 00:01:00,420

So we'll go ahead and double click them.



12

00:01:00,450 --> 00:01:08,100

So let me open this up here and we're going to zoom in so we can see this a little bit better.



13

00:01:08,100 --> 00:01:10,730

All right just a little more perfect.



14

00:01:10,740 --> 00:01:14,320

So what we're going to cover is first changing directories.



15

00:01:14,320 --> 00:01:15,930

Now what does that mean.



16

00:01:16,110 --> 00:01:21,540

Well changing directories is like a way of navigating through folders on your computer or different



17

00:01:21,540 --> 00:01:28,740

location such as the desktop documents and folders that might live within that section of your computer.



18

00:01:28,740 --> 00:01:34,890

So for example right here you can see that we are at my home directory.



19

00:01:35,130 --> 00:01:40,980

And to give you a visual of this what I want to do is open up my finder and I'm going to put it right



20

00:01:41,010 --> 00:01:42,060

next to this.



21

00:01:42,200 --> 00:01:42,920

OK.



22

00:01:43,090 --> 00:01:44,700

Let me make this a little bit smaller.



23

00:01:44,760 --> 00:01:45,280

OK.



24

00:01:45,540 --> 00:01:49,230

So right now this little house here right here Jay Ramnath.



25

00:01:49,260 --> 00:01:50,590

That is where I'm at.



26

00:01:50,610 --> 00:01:51,860

That's where I'm located.



27

00:01:51,930 --> 00:01:52,620

Right.



28

00:01:52,650 --> 00:01:55,830

And you can see inside of this directory.



29

00:01:55,860 --> 00:01:58,810

I've got a bunch of folders and things so we can go to.



30

00:01:59,040 --> 00:02:06,960

So to get onto the desk top forming sample we would write the command CD which stands for change directory



31

00:02:07,380 --> 00:02:12,580

and we can simply type out the word desktop and go ahead and press enter.



32

00:02:12,600 --> 00:02:17,370

Now you'll see in your terminal that the location has changed to the desktop.



33

00:02:17,370 --> 00:02:25,320

And we can do this again by listing out some items that are on my desktop so to view items that are



34

00:02:25,320 --> 00:02:27,510

on your desktop go ahead and write the command.



35

00:02:27,540 --> 00:02:29,060

LS can.



36

00:02:29,070 --> 00:02:32,760

This is going to list out everything that lives within this directory.



37

00:02:32,950 --> 00:02:36,480

So on my desktop you can see that I have a couple of folders here.



38

00:02:36,800 --> 00:02:37,430

All right.



39

00:02:37,470 --> 00:02:43,980

And if we switch over here in the Finder you can see that the same folders that appear in my terminal



40

00:02:44,040 --> 00:02:45,960

are also here in the Finder.



41

00:02:45,960 --> 00:02:50,330

All right so let's dive a little bit more into how to change directories.



42

00:02:50,340 --> 00:02:53,860

So I've got this folder on my desktop called first Durm.



43

00:02:53,880 --> 00:02:55,630

So her first directory.



44

00:02:55,890 --> 00:03:04,020

So if I want to get to this I'm going to simply type in CD and I'm going to type in first turn this



45

00:03:04,020 --> 00:03:06,480

is taking me into the first directory here.



46

00:03:06,840 --> 00:03:12,300

And then if we type out less to list out the items in here you'll see that I have a couple of files



47

00:03:12,690 --> 00:03:13,980

and another folder.



48

00:03:14,040 --> 00:03:15,750

So over here in Finder.



49

00:03:15,870 --> 00:03:21,330

Why don't we go ahead and click that and you'll see that we're looking at the same files and folders



50

00:03:21,660 --> 00:03:26,540

that we see here in the terminal and we can dive a little bit deeper in here.



51

00:03:26,580 --> 00:03:31,850

So let's go to CD and we're going to dive into the second directory.



52

00:03:32,100 --> 00:03:37,570

Now I just pressed the tab Kiem which auto completed the path here.



53

00:03:37,830 --> 00:03:38,520

And you can do that.



54

00:03:38,520 --> 00:03:44,890

It's kind of like a hockey I guess to finish typing out the directory that you'd like to enter.



55

00:03:45,090 --> 00:03:50,660

So I'm going to go ahead and click enter here and let's go ahead and list out everything that's in here.



56

00:03:50,820 --> 00:03:52,550

And we have two files.



57

00:03:52,560 --> 00:03:54,320

And another folder.



58

00:03:54,330 --> 00:03:59,550

All right so if we click over here we can see the same location where I'm at here.



59

00:03:59,880 --> 00:04:00,690

All right so cool.



60

00:04:00,690 --> 00:04:06,730

So we're learning how to dive deeper into directories into folders and listing those items.



61

00:04:06,930 --> 00:04:08,890

But how do we go back.



62

00:04:09,090 --> 00:04:10,420

Well there is a command for that.



63

00:04:10,440 --> 00:04:13,300

So simply we're going to change the directory.



64

00:04:13,500 --> 00:04:15,410

I'm typing it in over here.



65

00:04:15,750 --> 00:04:21,800

So we're going to change the directory make sure you're in your terminal type in CD space.



66

00:04:22,080 --> 00:04:23,170

Dot dot right.



67

00:04:23,190 --> 00:04:27,480

And this allows you to step back one level.



68

00:04:27,750 --> 00:04:31,940

All right so then we hit enter and you can see we're back into our first directory.



69

00:04:32,130 --> 00:04:36,480

So essentially what we did in the Finder is we're in our second directory here.



70

00:04:36,680 --> 00:04:37,320

OK.



71

00:04:37,380 --> 00:04:40,860

And we just clicked back to go to the first directory.



72

00:04:40,860 --> 00:04:44,500

I'm actually going to put this in an application view so it makes a little bit more sense here.



73

00:04:44,730 --> 00:04:51,320

So we're in the second directory up here and we just hit the back arrow pretty much and then went into



74

00:04:51,330 --> 00:04:53,980

the first directory here.



75

00:04:54,380 --> 00:04:55,530

Let me change this here.



76

00:04:55,530 --> 00:04:56,480

Perfect.



77

00:04:56,820 --> 00:04:57,180

OK.



78

00:04:57,210 --> 00:04:59,950

So that's a little bit about what's going on here.



79

00:04:59,970 --> 00:05:02,650

All right and then we can list out these items here.



80

00:05:02,670 --> 00:05:10,430

Now what I want you to do is if we want to get back to base like the the level that we were at right



81

00:05:10,430 --> 00:05:18,070

over here we could simply type in the command CD and that's going to take us back to the home base.



82

00:05:18,080 --> 00:05:24,570

So this is a really important thing to know how to do to be able to change directories through the terminal



83

00:05:24,620 --> 00:05:29,870

and what you're mainly going to be using this for is when you create projects that you're developing



84

00:05:29,930 --> 00:05:35,330

and you're going to have certain folders and different files in there and you might have to install



85

00:05:35,330 --> 00:05:40,190

certain dependencies or third party libraries and what you're going to need to do is you're going to



86

00:05:40,190 --> 00:05:46,310

need to know how to change directories into specific folders into your project so you can install or



87

00:05:46,310 --> 00:05:53,750

download specific dependencies and things like that into your project so congratulations we've just



88

00:05:53,750 --> 00:05:58,560

covered how to change directories navigate through our computer and list out the items.



89

00:05:58,580 --> 00:05:59,930

That's a wrap for this lesson.



90

00:05:59,930 --> 00:06:00,610

Let's move on.
