1
00:00:01,440 --> 00:00:05,250
Welcome back, ladies and gentlemen, this will be a short lecture here, are we going to start working

2
00:00:05,250 --> 00:00:06,900
on it before we start working on a project?

3
00:00:06,900 --> 00:00:09,210
We need to use the command line now.

4
00:00:09,390 --> 00:00:13,650
I'm going to use the window so it's a little bit different from the Mac, but I will try to explain

5
00:00:13,650 --> 00:00:15,010
the max commands as well.

6
00:00:15,270 --> 00:00:19,250
Now, command line is something that we need to install the back packages just later on.

7
00:00:19,470 --> 00:00:27,030
So if you have knowledge about using the command prompt or terminal in the max, then you are OK with

8
00:00:27,030 --> 00:00:27,450
this lecture.

9
00:00:27,450 --> 00:00:33,750
You can skip this lecture now in Mac, it's called terminal to open up the terminal and in Windows it's

10
00:00:33,750 --> 00:00:34,820
called command prompt.

11
00:00:35,010 --> 00:00:37,050
So how you can open it is to stop here.

12
00:00:37,170 --> 00:00:39,110
CMD and he enters.

13
00:00:39,130 --> 00:00:40,170
I'm using Windows 10.

14
00:00:40,350 --> 00:00:44,040
Right, so I can zoom in this one little bit to make it more visible.

15
00:00:44,040 --> 00:00:49,740
Now, here in the desktop, I do have you can create a folder here, empty folder, or you can use this

16
00:00:49,740 --> 00:00:56,220
MAPI starter so you can grab this from the resources because we're going to start working shortly with

17
00:00:56,220 --> 00:00:57,630
this file folder as well.

18
00:00:57,870 --> 00:01:02,850
OK, but if you want to sit back and watch it, then just please do this because I know a lot of you

19
00:01:02,850 --> 00:01:04,470
guys just want to do that.

20
00:01:04,470 --> 00:01:07,450
And after that you can start working on your projects.

21
00:01:07,520 --> 00:01:09,840
OK, now I do have a couple of folders here.

22
00:01:11,190 --> 00:01:19,450
So what I can do here in Linux or Max, it allows and it will list all of the directories, but in Windows

23
00:01:19,470 --> 00:01:22,960
is D.R and it will list all of the directories here.

24
00:01:22,960 --> 00:01:26,150
I have 22 directories, three files, stuff like that.

25
00:01:26,460 --> 00:01:28,440
What if I want to go to the desktop?

26
00:01:28,440 --> 00:01:30,180
What everything is located for me.

27
00:01:30,190 --> 00:01:34,140
OK, now I need to go see in the name.

28
00:01:34,830 --> 00:01:38,310
So desktop in the name of the directory down when I go.

29
00:01:38,790 --> 00:01:39,150
Right.

30
00:01:40,350 --> 00:01:50,730
And this will if I put, if I press enter I will go, I will change from this until this up to this

31
00:01:50,730 --> 00:01:53,910
rupture is going to go restaged slash that stuff.

32
00:01:53,920 --> 00:01:55,910
So that's it is my desktop.

33
00:01:56,160 --> 00:01:58,120
So if I use D-R.

34
00:01:58,500 --> 00:02:02,490
So actually I did explain CD means change directorate's.

35
00:02:02,490 --> 00:02:04,770
The same for Macs and it's the same for Linux.

36
00:02:05,160 --> 00:02:10,650
Now I can use Elst for week for Macs or D-R to see what's happening here.

37
00:02:10,650 --> 00:02:13,650
Now I do have a couple of things here.

38
00:02:13,650 --> 00:02:16,800
I do have two files and five directories.

39
00:02:17,130 --> 00:02:17,520
Right.

40
00:02:17,810 --> 00:02:20,400
And I want to go to this map starter.

41
00:02:20,790 --> 00:02:21,120
Good.

42
00:02:21,120 --> 00:02:24,930
So I'm going to use change director again, space moppy.

43
00:02:25,110 --> 00:02:32,160
Emma, you can press step here and it will give you it will out the complete until here.

44
00:02:32,160 --> 00:02:32,520
Why?

45
00:02:32,700 --> 00:02:34,350
Because I have to with the same name.

46
00:02:34,770 --> 00:02:39,330
So I need to start typing until something is different from this too.

47
00:02:39,510 --> 00:02:42,960
So the terminal will know what I'm trying to do.

48
00:02:42,960 --> 00:02:49,770
So now if I type stab again it will complete the second one because OK, this mapi dash is different

49
00:02:49,770 --> 00:02:50,430
than the mapping.

50
00:02:50,430 --> 00:02:50,760
Right.

51
00:02:51,060 --> 00:02:52,140
And if I click enter.

52
00:02:52,350 --> 00:02:54,300
So I'm inside this map mapi started.

53
00:02:54,330 --> 00:02:57,450
OK, let me show you what I have in this map started.

54
00:02:57,690 --> 00:03:01,620
I do have this distribution folder and I do have the source folder.

55
00:03:01,620 --> 00:03:01,950
Right.

56
00:03:02,310 --> 00:03:12,360
OK, now if I use the the R or else it will give me just exactly what I'm trying to tell you now so

57
00:03:12,360 --> 00:03:14,460
you know how to go to a directory.

58
00:03:14,460 --> 00:03:15,900
But what if you want to go back.

59
00:03:16,590 --> 00:03:21,420
So if you want to go one level back, so you're going to see the space double dots.

60
00:03:22,650 --> 00:03:23,880
Right, and hit enter.

61
00:03:24,060 --> 00:03:28,920
So remember I'm here in the map started started also when I hit enter, I will go back to the desktop

62
00:03:30,420 --> 00:03:37,260
cuz now I'm back into the desktop and that is how you can move up and down.

63
00:03:37,590 --> 00:03:40,890
One more thing because I've run a couple of commands here.

64
00:03:41,040 --> 00:03:48,360
I can use the keyboards up and down arrows right here, and this will list all of these commands that

65
00:03:48,360 --> 00:03:49,170
I've used before.

66
00:03:49,440 --> 00:03:51,420
So I want to go back to DC.

67
00:03:51,420 --> 00:03:52,250
The map you started.

68
00:03:52,260 --> 00:03:53,070
I can enter.

69
00:03:53,220 --> 00:03:54,540
I don't have to type it again.

70
00:03:55,110 --> 00:03:55,770
That's cool.

71
00:03:56,070 --> 00:03:56,640
Nice.

72
00:03:56,940 --> 00:04:01,470
So what we can do here, we want to start using.

73
00:04:01,770 --> 00:04:03,990
The next part is to create a folder, actually.

74
00:04:04,260 --> 00:04:04,650
Right.

75
00:04:05,040 --> 00:04:10,470
So the folder we can create we emcdda are and the name of the folder.

76
00:04:10,560 --> 00:04:10,950
Right.

77
00:04:11,190 --> 00:04:15,360
So we can say EMK make directory.

78
00:04:16,050 --> 00:04:19,950
So I want to make the ah I want to create a folder inside a map estado.

79
00:04:19,950 --> 00:04:20,220
Right.

80
00:04:20,370 --> 00:04:28,500
And I'm going to call it a new folder and I'm going to hit enter.

81
00:04:29,310 --> 00:04:36,270
By the way, this is the same for this is pretty much seen for Macs and Windows.

82
00:04:36,570 --> 00:04:38,430
Let's confirm that I have a new folder here.

83
00:04:38,460 --> 00:04:38,760
Yep.

84
00:04:38,970 --> 00:04:39,690
It's empty.

85
00:04:40,170 --> 00:04:44,670
So now you know how to create a folder, but how we can create a file.

86
00:04:44,820 --> 00:04:52,440
So in Mac and Linux we need to write touch in the name of the file index that J is right.

87
00:04:52,710 --> 00:04:55,140
So I'm not going to run this command because it's not going to execute.

88
00:04:55,350 --> 00:04:57,240
So this is for for Macs and Linux.

89
00:04:57,450 --> 00:04:59,730
But if I want to create a file in window.

90
00:04:59,870 --> 00:05:06,770
It's a copy, no capital and you ever single out an indexed object.

91
00:05:07,100 --> 00:05:10,130
This, ladies and gentlemen, will create a file here.

92
00:05:11,780 --> 00:05:12,790
Oops, what's happening?

93
00:05:16,620 --> 00:05:26,280
And why is that showing Gobbi index, Jarius, let's put it the oh, right, because I was not inside

94
00:05:26,280 --> 00:05:26,820
this folder.

95
00:05:26,820 --> 00:05:28,110
I'm just going to delete it from here.

96
00:05:28,300 --> 00:05:30,090
I'm going to show you how you can delete it here.

97
00:05:30,090 --> 00:05:30,340
Right.

98
00:05:30,540 --> 00:05:35,250
So I need to go see the new folder and I'm going to say copy.

99
00:05:38,570 --> 00:05:40,820
No index, not jazz.

100
00:05:41,020 --> 00:05:44,760
OK, now if I go DVR, I will see that file here, right?

101
00:05:45,010 --> 00:05:46,870
I got confused, ladies and gentlemen, a little bit.

102
00:05:47,220 --> 00:05:48,810
It is I do have this file.

103
00:05:49,080 --> 00:05:56,710
Now, this is in the Windows, but in in Linux or Macs, you need to use touch the name of the file.

104
00:05:56,720 --> 00:05:59,570
But first, make sure that you are inside this new folder.

105
00:05:59,930 --> 00:06:00,270
Cool.

106
00:06:02,330 --> 00:06:08,030
Now let's learn how to copy these indexes, not just file from the new folder and put it back to the

107
00:06:08,030 --> 00:06:10,540
map you started or the parent directory.

108
00:06:10,550 --> 00:06:10,810
Right.

109
00:06:11,120 --> 00:06:12,170
So I want to go here.

110
00:06:12,170 --> 00:06:12,530
Sorry.

111
00:06:12,650 --> 00:06:14,060
I want to go from this folder.

112
00:06:14,180 --> 00:06:16,160
I want to copy it and I want to put it here.

113
00:06:16,580 --> 00:06:19,550
OK, so in it's a little bit different in windows.

114
00:06:19,550 --> 00:06:22,670
It's a little bit different in, in, in the Mac.

115
00:06:22,890 --> 00:06:31,580
OK, in a map in the Mac is C.p copy in the name of the file for example, index that J.S. and the where

116
00:06:31,580 --> 00:06:32,500
you want to be copied.

117
00:06:32,690 --> 00:06:36,560
So I'm going to go one level up, two dots and that will go there.

118
00:06:36,650 --> 00:06:43,610
So use this one if you use Mac, but if you're using windows like me, what you need to do is you need

119
00:06:43,610 --> 00:06:45,620
to use the word copy.

120
00:06:46,790 --> 00:06:47,210
Right.

121
00:06:47,900 --> 00:06:51,050
Index that J.S. sorry.

122
00:06:51,320 --> 00:06:56,310
And I want to go to the parent folder and I'm going to hit enter and say one file copy.

123
00:06:56,690 --> 00:06:59,010
Now here is the index.

124
00:06:59,110 --> 00:07:04,400
Jazz is dear, but I do have in the new folder, the same file is still there because I didn't delete

125
00:07:04,400 --> 00:07:04,520
it.

126
00:07:04,520 --> 00:07:05,560
It just copy it.

127
00:07:06,110 --> 00:07:06,430
Good.

128
00:07:06,650 --> 00:07:11,960
This is different now once more you need to use.

129
00:07:12,890 --> 00:07:22,120
So for example here I use copy index that js and and also the the way it needs to go in here in Linux

130
00:07:22,130 --> 00:07:23,620
or Mac, you need to use C.p.

131
00:07:25,640 --> 00:07:30,350
OK, let's play a little bit more here from inside this new folder again, and I'm going to create a

132
00:07:30,350 --> 00:07:31,760
new file.

133
00:07:31,760 --> 00:07:32,840
So I'm going to say copy.

134
00:07:33,920 --> 00:07:40,880
No Abduh is and this will create sorry.

135
00:07:40,880 --> 00:07:46,030
Instead of yeah I had a mistake spelling mistakes.

136
00:07:46,160 --> 00:07:48,620
I did copy, no apologies.

137
00:07:48,620 --> 00:07:50,930
And that will create additional file in the new folder.

138
00:07:51,320 --> 00:07:57,920
And I now want to move I want to completely move these at the Gere's from this new folder into MAPI

139
00:07:57,920 --> 00:07:58,430
starter.

140
00:07:58,700 --> 00:08:00,680
So that is not the same as a copy.

141
00:08:00,710 --> 00:08:05,300
Now here are used copy and you should use touch if you use wind.

142
00:08:05,750 --> 00:08:09,130
If you're using Macs right o k.

143
00:08:09,140 --> 00:08:12,290
Now how we can move these files.

144
00:08:12,560 --> 00:08:18,530
So in Mac is M.V. and in the windows is move.

145
00:08:18,740 --> 00:08:21,590
So I'm going to use move apgar's.

146
00:08:21,590 --> 00:08:26,480
But remember you need to be inside the folder and you need to specify where you need to move.

147
00:08:26,750 --> 00:08:27,110
Right.

148
00:08:27,140 --> 00:08:29,180
So I want to move it back to the parent folder.

149
00:08:29,390 --> 00:08:32,870
I'm going to hit enter now in here.

150
00:08:32,870 --> 00:08:35,480
It is the Japanese there, but it's not going to be here.

151
00:08:35,480 --> 00:08:36,110
It's moved.

152
00:08:36,620 --> 00:08:37,010
Right.

153
00:08:37,130 --> 00:08:42,440
So now you know how to create file, create a folder, copy a file and move the file.

154
00:08:42,440 --> 00:08:42,880
Good.

155
00:08:43,190 --> 00:08:50,000
Now, what about to delete the swells iMac for the leading the file, for example.

156
00:08:50,000 --> 00:08:57,200
I do have in new here I do have a new folder, one index of jazz and you can confirm this by D.R or

157
00:08:57,200 --> 00:08:59,390
else right here it is one file.

158
00:08:59,600 --> 00:09:02,450
So I just want to delete this one in Mac.

159
00:09:02,660 --> 00:09:07,730
It's R.M. Index that JS and you're going to hit enter now.

160
00:09:07,730 --> 00:09:09,710
This will delete the file permanently.

161
00:09:09,830 --> 00:09:13,640
You will not be able to find it, delete it permanently from everywhere.

162
00:09:13,910 --> 00:09:20,530
But in windows it's Dille Index Digest's.

163
00:09:20,540 --> 00:09:24,380
Right, so if you enter it will not show me anything.

164
00:09:24,650 --> 00:09:28,250
But if I go back here, here is I don't have this index ojars.

165
00:09:28,490 --> 00:09:30,110
I do have those two here.

166
00:09:30,110 --> 00:09:31,550
Right here it is.

167
00:09:31,550 --> 00:09:32,780
And that means it's working.

168
00:09:32,790 --> 00:09:37,250
OK, now I want to go one back CD, two dots.

169
00:09:37,970 --> 00:09:39,180
So I mean mapi starting.

170
00:09:39,200 --> 00:09:44,990
I'm not inside this new folder so show you how you can delete a file, but I need to show you how you

171
00:09:44,990 --> 00:09:46,430
need to delete a folder.

172
00:09:46,610 --> 00:09:51,710
So in a Mac it's R.M. Dash or so these are

173
00:09:54,800 --> 00:09:57,050
so these are is a flag.

174
00:09:57,050 --> 00:09:58,370
There are is a flag.

175
00:09:58,370 --> 00:10:04,130
So R.M. flag armies delete recursively everything that it's inside the folder.

176
00:10:04,340 --> 00:10:08,750
For example, if you have files it will delete all of the files one by one.

177
00:10:08,750 --> 00:10:12,890
So or dash or in the name of the folder.

178
00:10:12,890 --> 00:10:14,390
New folder.

179
00:10:14,390 --> 00:10:14,720
Right.

180
00:10:15,140 --> 00:10:18,260
But in Windows it's a little bit different.

181
00:10:18,500 --> 00:10:21,350
So you need to hit enter in order this to be executed in Mac.

182
00:10:21,530 --> 00:10:34,370
But Windows is are m d.r so remove directory slash forward slash s and the any new new folder.

183
00:10:34,940 --> 00:10:35,330
Right.

184
00:10:35,540 --> 00:10:37,430
So I'm going to enter into a.

185
00:10:37,490 --> 00:10:38,040
Sure.

186
00:10:38,180 --> 00:10:40,220
Yes, that's it.

187
00:10:40,400 --> 00:10:45,620
Now, if I use Diaa or else I'm not going to have that directory anymore.

188
00:10:45,680 --> 00:10:46,690
There it is.

189
00:10:46,970 --> 00:10:48,440
I don't have it right.

190
00:10:49,160 --> 00:10:50,960
That is pretty much it.

191
00:10:50,960 --> 00:10:55,940
How you can delete all of those files now.

192
00:10:57,530 --> 00:10:59,660
Now, we have two files here, app and.

193
00:11:00,140 --> 00:11:05,840
I just want to delete so I can just show you how you can delete two files in one go so you can say Dell

194
00:11:07,430 --> 00:11:11,660
App Jars and index dodgiest.

195
00:11:12,080 --> 00:11:15,410
So I'm going to hit enter and here you go.

196
00:11:15,410 --> 00:11:16,400
You don't have it anymore.

197
00:11:16,410 --> 00:11:20,870
If I put the I want the ah they're not there.

198
00:11:21,050 --> 00:11:27,760
So the same was are in Mac R.M. Index, not just an app that jazz.

199
00:11:27,770 --> 00:11:28,050
Right.

200
00:11:28,510 --> 00:11:29,450
So if you're using Mac.

201
00:11:29,670 --> 00:11:29,980
Good.

202
00:11:30,860 --> 00:11:36,530
Now one more thing that I want to show you is how you can open a file inside here.

203
00:11:36,530 --> 00:11:47,880
So inside my source folder, I do have this index so I need to go CD sirc right in in Mac it's open.

204
00:11:48,530 --> 00:11:53,720
So if I go DIY the are or else I will be able to see this index.

205
00:11:53,720 --> 00:11:54,000
Right.

206
00:11:54,200 --> 00:11:55,610
So I want to open this file.

207
00:11:55,610 --> 00:12:01,670
So in Mac is open index that HTML and you need to enter.

208
00:12:01,910 --> 00:12:11,970
It's not going to work for me because for me the windows you need to see start index dot html in here.

209
00:12:11,990 --> 00:12:14,340
This is going to open up in a local browser.

210
00:12:14,690 --> 00:12:20,270
Now for me the default browser is Firefox and that's why it's opening for you.

211
00:12:20,270 --> 00:12:21,140
Maybe something else.

212
00:12:21,510 --> 00:12:26,870
And here it's loading the file, but it's loading without the stylus.

213
00:12:26,870 --> 00:12:28,130
That's why it's like this, right.

214
00:12:28,880 --> 00:12:29,490
Oh good.

215
00:12:30,350 --> 00:12:33,970
Now you know how to create files, move through directories.

216
00:12:34,190 --> 00:12:37,040
And one more thing in Mac you can use clear.

217
00:12:37,760 --> 00:12:38,240
Right.

218
00:12:38,360 --> 00:12:40,610
To clear this entire thing.

219
00:12:40,610 --> 00:12:58,700
Entire command prompt in windows a c o l r or wait, it was s.L pass or it is not why I said so in windows.

220
00:12:58,700 --> 00:13:04,550
This one in Mac clear like c l.

221
00:13:04,550 --> 00:13:06,200
S he'd enter.

222
00:13:06,380 --> 00:13:07,910
You're going to clean the entire screen.

223
00:13:08,150 --> 00:13:08,950
That is pretty much it.

224
00:13:08,960 --> 00:13:13,370
So you know how to clear the screen, you know how to create files, you know how to navigate up and

225
00:13:13,370 --> 00:13:14,750
down through the directories.

226
00:13:14,930 --> 00:13:16,670
You know how to create new directory.

227
00:13:16,940 --> 00:13:21,920
You know how to move a file, a copy file from one place to some other place.

228
00:13:22,250 --> 00:13:23,510
You can delete that file.

229
00:13:23,510 --> 00:13:28,850
You can delete that directory, you can delete multiple files, and also you can open up files through

230
00:13:28,850 --> 00:13:29,570
the terminal.

231
00:13:29,870 --> 00:13:32,600
So, yeah, that is pretty much it for this lecture.

232
00:13:32,600 --> 00:13:36,740
I hope you enjoyed and learn a lot about this command problem.

233
00:13:36,950 --> 00:13:38,180
Right, because you're going to need it.

234
00:13:38,390 --> 00:13:40,690
This for next lecture.

235
00:13:40,700 --> 00:13:42,410
We're going to install a couple of things for this.

236
00:13:42,680 --> 00:13:49,370
And I'm sure now that you know how this is working and that's pretty much it, I hope I'm going to see

237
00:13:49,370 --> 00:13:50,900
you in the next one and stay safe.
