1
00:00:00,000 --> 00:00:02,790
Okay, let's do a quick little crash course, a Command Line

2
00:00:02,800 --> 00:00:04,600
crash course for Windows.

3
00:00:04,610 --> 00:00:07,270
So throughout this course and through a lot of other videos

4
00:00:07,280 --> 00:00:10,060
on the Internet, you're going to see a lot of Unix like commands,

5
00:00:10,260 --> 00:00:12,930
so commands like 'ls' or 'ls -la',

6
00:00:12,940 --> 00:00:15,510
and that clearly is not going to work in our Command Prompt.

7
00:00:15,700 --> 00:00:18,610
And just to take a quick step back there, if you're wondering,

8
00:00:18,620 --> 00:00:19,960
"Oh, Kalob, what is a 'Command Prompt'?",

9
00:00:19,970 --> 00:00:23,390
'Command Prompt is when I go down here and type 'Command Prompt',

10
00:00:23,400 --> 00:00:25,340
you can 'Run as an administrator',

11
00:00:25,350 --> 00:00:26,960
it might ask you, "Are you sure?"

12
00:00:26,970 --> 00:00:29,570
You say "Yes", you click the 'Yes' button, and it will bring

13
00:00:29,580 --> 00:00:30,620
you to something like this.

14
00:00:30,630 --> 00:00:33,830
So if you want to see everything that's in a folder instead

15
00:00:33,840 --> 00:00:37,190
of 'ls -la', which is what you'll often see on the Internet,

16
00:00:37,220 --> 00:00:42,210
you can write 'D-I-R', 'dir', and this will show you everything

17
00:00:42,210 --> 00:00:44,100
inside of a directory, and look at all that.

18
00:00:44,160 --> 00:00:46,290
I have a lot of things inside of this directory.

19
00:00:46,590 --> 00:00:48,090
Now, which directory am I on?

20
00:00:48,300 --> 00:00:52,100
I am on 'C' drive, 'Windows\system32'.

21
00:00:52,120 --> 00:00:55,480
Now to change your directory, you can type 'cd' to change your

22
00:00:55,480 --> 00:00:58,600
directory, '../' will move you up one directory, and you can

23
00:00:58,600 --> 00:00:59,700
actually see that it's

24
00:00:59,700 --> 00:01:04,800
[no audio]

25
00:01:04,800 --> 00:01:07,099
changing here. I can do that again.

26
00:01:07,110 --> 00:01:08,930
'cd ../'.

27
00:01:08,930 --> 00:01:11,030
It goes up a directory, and then I can do

28
00:01:11,040 --> 00:01:12,440
'dir', see what's in here.

29
00:01:12,440 --> 00:01:15,200
We've got a few things, but I usually want to go to the 'Users'

30
00:01:15,200 --> 00:01:17,100
because that's usually where you're going to be working out

31
00:01:17,130 --> 00:01:18,200
of, is your user profile.

32
00:01:18,300 --> 00:01:20,800
So you could do 'cd Users'.

33
00:01:21,260 --> 00:01:23,510
And then I can do a 'dir' in here.

34
00:01:24,500 --> 00:01:29,000
And I have a user called 'kalob', and a directory called 'public'.

35
00:01:29,000 --> 00:01:33,000
So directory called 'kalob' and 'public'. So let's 'cd kalob',

36
00:01:33,010 --> 00:01:35,640
and this is likely going to say whatever your name is on Windows,

37
00:01:36,630 --> 00:01:39,370
'dir', and I can see all sorts of files in here.

38
00:01:39,480 --> 00:01:42,270
Now, let's say you wanted a folder just for your projects.

39
00:01:42,280 --> 00:01:46,290
You could make a directory so 'mk', and then directory, 'dir', and

40
00:01:46,300 --> 00:01:52,000
then you could call it like 'YourProjects'. If I do 'dir'

41
00:01:52,000 --> 00:01:55,500
you'll see the folder in here called 'YourProjects'.

42
00:01:55,530 --> 00:01:56,610
So now I can go in there.

43
00:01:56,760 --> 00:02:00,360
'cd YourProjects', change directory into 'YourProjects'.

44
00:02:00,660 --> 00:02:03,300
'dir', you'll see, there's nothing in here, zero bytes.

45
00:02:03,300 --> 00:02:06,000
And I can create a new Python file in here if I wanted to.

46
00:02:06,040 --> 00:02:09,580
Now, I'm also inside of my profile at this point.

47
00:02:09,758 --> 00:02:13,509
So if you're using VS Code or PyCharm or some sort of text

48
00:02:13,509 --> 00:02:16,240
editor, you can put all of your files in here and you'll

49
00:02:16,250 --> 00:02:17,290
be able to see them as well.

50
00:02:17,480 --> 00:02:21,800
And just for instance, I created a folder called 'YourProjects'

51
00:02:21,810 --> 00:02:22,790
inside of my account.

52
00:02:22,800 --> 00:02:23,810
Let's go explore that.

53
00:02:25,400 --> 00:02:26,800
Let's go to 'My Documents'.

54
00:02:26,880 --> 00:02:28,530
And, well, that's kind of cool.

55
00:02:28,530 --> 00:02:30,100
I did not realize that would be there, but there's

56
00:02:30,100 --> 00:02:31,500
'PythonScripts' already in there.

57
00:02:31,600 --> 00:02:39,400
Let's go to 'PC', 'C Drive', 'Users', and this is just matching this

58
00:02:39,400 --> 00:02:40,400
location down here.

59
00:02:41,500 --> 00:02:43,800
So I'm going to go into 'kalob', and I'll have a folder,

60
00:02:43,800 --> 00:02:45,000
there it is, 'YourProjects'.

61
00:02:45,240 --> 00:02:47,340
And then you could create a new file in here.

62
00:02:47,350 --> 00:02:49,440
You could open up your text editor.

63
00:02:49,440 --> 00:02:50,730
You code editor.

64
00:02:50,740 --> 00:02:52,410
You could create a new project in here.

65
00:02:52,420 --> 00:02:53,940
You can do all sorts of stuff in here.

66
00:02:53,980 --> 00:02:57,190
But the main thing to know at this point is really you need

67
00:02:57,190 --> 00:02:59,900
to know, how to change directories, go up a level.

68
00:02:59,950 --> 00:03:02,910
You need to be able to go into a directory, so that's just

69
00:03:02,920 --> 00:03:05,700
like 'cd', whatever your folder is called. You need to know

70
00:03:05,700 --> 00:03:10,400
what is in your directory or in your folder with 'd-i-r', 'dir', just like that.

71
00:03:10,480 --> 00:03:13,380
And then lastly, you need to be able to run your Python files,

72
00:03:13,390 --> 00:03:16,170
and running your Python file is as easy as 'py',

73
00:03:16,180 --> 00:03:18,150
and then your file, '.py'.

74
00:03:18,160 --> 00:03:20,220
So 'your_file.py',

75
00:03:20,560 --> 00:03:23,590
assuming 'your_file.py' actually exists.

76
00:03:23,940 --> 00:03:27,570
Last but not least, you might want to get into your Python

77
00:03:27,580 --> 00:03:28,770
shell, your Python IDLE.

78
00:03:28,800 --> 00:03:31,650
All you have to do is type 'py', and you can write all of your

79
00:03:31,660 --> 00:03:32,970
own Python in here as well.

80
00:03:33,090 --> 00:03:35,730
If you ever get stuck in here and you want to get out, you

81
00:03:35,740 --> 00:03:39,560
just type 'quit()', opening and closing parentheses, and you will

82
00:03:39,560 --> 00:03:40,700
get out of it as well.

83
00:03:40,700 --> 00:03:44,200
If at any point in time, you're like, "Oh, no, I accidentally closed this",

84
00:03:44,200 --> 00:03:45,200
that's not a problem,

85
00:03:45,260 --> 00:03:48,170
just go back here, and find your 'Command Prompt',

86
00:03:48,300 --> 00:03:50,900
I always like to 'Run as an administrator'.

87
00:03:52,600 --> 00:03:55,500
Yup, and we're back to where we usually start off.

88
00:03:55,740 --> 00:03:58,830
So that is a quick command line crash course on Windows.

89
00:03:58,840 --> 00:04:01,470
You don't really need to know too much more other than that

90
00:04:01,480 --> 00:04:02,970
for the rest of this course.
