00:00:00,240 --> 00:00:01,800
Hello there, you beautiful person.

2
00:00:01,830 --> 00:00:03,150
Well, well, well.

3
00:00:03,150 --> 00:00:06,240
You must be feeling super proud of yourself right now, right?

4
00:00:06,270 --> 00:00:08,820
You've come so far in this section of the course.

5
00:00:08,820 --> 00:00:13,440
So to fully celebrate that, I wanted to make a video and have a quick recap so that you can soak in

6
00:00:13,440 --> 00:00:16,920
all the awesome stuff you've learned in this section of the course.

7
00:00:16,920 --> 00:00:21,570
So you started off with the very basics and you learned how to open and close the terminal using graphical

8
00:00:21,570 --> 00:00:25,320
methods and by using our now beloved keyboard shortcuts.

9
00:00:25,320 --> 00:00:29,520
And it was all very strange to you at first, but you jumped right in anyway, and you started typing

10
00:00:29,520 --> 00:00:31,530
out and using your first commands.

11
00:00:31,530 --> 00:00:36,840
You saw the date command, the Cal Command, and the Echo Command, and you saw how to clear your terminal

12
00:00:36,840 --> 00:00:37,380
history.

13
00:00:37,380 --> 00:00:40,260
We don't want any spies looking at history after all, do we?

14
00:00:40,710 --> 00:00:44,910
Now, you were making progress, but it was all kind of weird, and you probably weren't too sure of

15
00:00:44,910 --> 00:00:47,190
what was actually going on when you ran a command.

16
00:00:47,190 --> 00:00:50,190
So then you learn the difference between the terminal and the shell.

17
00:00:50,190 --> 00:00:54,420
You know that the shell is what interprets the commands that you type, just like you interpret the

18
00:00:54,420 --> 00:00:59,370
meanings of words that you read and when you understood what commands actually were, you learn the

19
00:00:59,370 --> 00:01:04,319
general structure of a command, learning the commands, follow a command name, options, arguments,

20
00:01:04,319 --> 00:01:05,040
structure.

21
00:01:05,040 --> 00:01:11,070
Okay, now, because it became clear that although commands follow a similar structure, they do vary

22
00:01:11,070 --> 00:01:12,600
quite a bit in their usage.

23
00:01:12,600 --> 00:01:16,920
They each have their own specific options and use cases and it would be impossible to memorize them

24
00:01:16,920 --> 00:01:17,280
all.

25
00:01:17,280 --> 00:01:19,890
So you learned how to look in the Linux manual.

26
00:01:19,890 --> 00:01:24,390
You learned how the manual was broken up, and you saw how to search for terms and read the manual pages

27
00:01:24,390 --> 00:01:28,860
and how to learn new things for yourself and find things as and when you need them, rather than having

28
00:01:28,860 --> 00:01:29,910
to memorize everything.

29
00:01:29,910 --> 00:01:33,750
So it's like having your own personal search engine for your computer, which is pretty incredible in

30
00:01:33,750 --> 00:01:34,440
my opinion.

31
00:01:34,440 --> 00:01:39,360
Now then we took our discussion even deeper and you learn that commands can take input, a standard

32
00:01:39,360 --> 00:01:44,700
input and command line arguments, and they can give output via standard output and standard error data

33
00:01:44,700 --> 00:01:45,270
streams.

34
00:01:45,570 --> 00:01:50,340
So I had to redirect these data streams to wherever you wish and how to pipe together different commands

35
00:01:50,340 --> 00:01:57,180
to build powerful pipelines and how to use the T command and the x args command for extra pipeline flexibility.

36
00:01:57,180 --> 00:02:01,470
And this really is amazing how far you've come in such a short amount of time.

37
00:02:01,470 --> 00:02:03,690
So I wanted to make this video to congratulate you on your progress.

38
00:02:03,690 --> 00:02:06,210
So far, so well done, you little computer genius.

39
00:02:06,210 --> 00:02:10,110
You know, in the next section, you're going to learn about navigating the Linux file system, and

40
00:02:10,110 --> 00:02:13,230
you'll also learn some new building blocks to use in your pipelines.

41
00:02:13,230 --> 00:02:16,050
But before that, I have a project for you to complete.

42
00:02:16,080 --> 00:02:20,130
Now the project will challenge you to build your very own Linux command pipeline.

43
00:02:20,250 --> 00:02:24,090
It's going to be awesome, and it will serve as a badge of honor that you have learned everything that

44
00:02:24,090 --> 00:02:26,400
we've covered in this section so that you can feel confident.

45
00:02:26,400 --> 00:02:29,430
Moving on now, in the next video, I'm going to be giving you your project brief.

46
00:02:29,430 --> 00:02:31,140
So congratulations once again.

47
00:02:31,140 --> 00:02:32,700
You're doing amazingly.

48
00:02:32,700 --> 00:02:33,750
And I'll see you there.
