1
00:00:00,180 --> 00:00:06,200
Now, guys, in this lecture, we are going to see export, come on, so export, come on is a building

2
00:00:06,220 --> 00:00:08,630
utility of Linux Bassal.

3
00:00:09,090 --> 00:00:16,310
So it is used to ensure the involvement of variables and functions to be passed to the child processors

4
00:00:16,620 --> 00:00:19,710
so it does not affect the existent environment variables.

5
00:00:19,710 --> 00:00:21,790
So this is the thing on the environment.

6
00:00:21,790 --> 00:00:29,370
The variables are set when we open a new channel Sezen at any time if we change any variable value so

7
00:00:29,370 --> 00:00:32,070
the cell has no way to select that change.

8
00:00:32,550 --> 00:00:39,150
And Export Command allows us to update the current session about the changes that have been made with

9
00:00:39,150 --> 00:00:40,740
exported variable.

10
00:00:41,250 --> 00:00:44,560
So we do not need to wait to start a new cell session.

11
00:00:45,030 --> 00:00:48,390
So now let's see what will be the syntax of using this.

12
00:00:49,650 --> 00:00:51,470
So syntax will very clear.

13
00:00:51,480 --> 00:00:53,010
Let me open the Domhnall first.

14
00:00:55,300 --> 00:01:03,730
OK, so let's let me zoom for zooming it simply or simply hold control button and it will start zooming

15
00:01:03,730 --> 00:01:03,890
in.

16
00:01:03,910 --> 00:01:07,280
OK, so this is the terminal that we have on Austin, Texas.

17
00:01:07,300 --> 00:01:11,740
I'm going to give it is it will be like explode and with the space.

18
00:01:12,460 --> 00:01:18,820
This is for F for function and ln here you can use like this.

19
00:01:19,180 --> 00:01:19,810
Okay.

20
00:01:20,230 --> 00:01:24,660
You can also use neme, but hyphen is pretty small.

21
00:01:24,670 --> 00:01:31,110
So use this and you can use it like name and is equal to value.

22
00:01:31,810 --> 00:01:36,180
So this is like this, this is like this particular thing this close.

23
00:01:36,190 --> 00:01:37,110
This, this.

24
00:01:37,260 --> 00:01:40,240
OK, so this is the basic syntax of using export.

25
00:01:40,250 --> 00:01:44,980
So don't confuse if you're not understanding new and if you're not getting it, I will teach you how

26
00:01:44,980 --> 00:01:45,610
you can do this.

27
00:01:45,850 --> 00:01:46,620
OK, guys.

28
00:01:46,960 --> 00:01:52,510
So now first of all, we are going to see the export command without any kind of argument.

29
00:01:52,540 --> 00:01:58,160
So the basic export command will display all the exported environment variable off of a system.

30
00:01:58,180 --> 00:02:04,240
So how you can use it simply type export and hit enter signal.

31
00:02:04,240 --> 00:02:13,210
Guys, you can see that we are having all the more and variable that that exported all over the system.

32
00:02:13,480 --> 00:02:16,120
Let me scroll it up.

33
00:02:16,120 --> 00:02:19,570
You will find all the unwanted variables organized.

34
00:02:20,500 --> 00:02:23,840
OK, so the next thing first of all, let me clear this.

35
00:02:23,840 --> 00:02:25,550
So now we have cleared the window.

36
00:02:25,840 --> 00:02:31,210
Now let's see how to display all exported variable on a current cell.

37
00:02:31,240 --> 00:02:33,580
So as you can see, I'm the road user.

38
00:02:33,940 --> 00:02:34,720
Road user.

39
00:02:35,020 --> 00:02:41,080
So don't worry, if you're not getting it, I will teach you how to become a road user later on in the

40
00:02:41,080 --> 00:02:41,440
school.

41
00:02:41,490 --> 00:02:48,570
So this is not necessary to talk about the road user in this current starting lectures of discourse.

42
00:02:48,580 --> 00:02:52,760
That is why I'm not taking the road user section yet.

43
00:02:52,930 --> 00:02:55,600
I will talk about road user later on in discourse.

44
00:02:55,780 --> 00:03:00,640
OK, so now let's see how to display all the export variables on currency.

45
00:03:00,990 --> 00:03:04,480
So similar to this, we all exported variables on the current cell.

46
00:03:04,510 --> 00:03:12,010
We are going to use like export hyphen P, so this will simply list out all the current variables on

47
00:03:12,370 --> 00:03:15,310
all the all the, all the important variables.

48
00:03:15,310 --> 00:03:16,170
Honokaa intellectually.

49
00:03:16,390 --> 00:03:21,150
Okay, so these all are the environmental variables on the correlation.

50
00:03:21,760 --> 00:03:22,260
OK.

51
00:03:22,570 --> 00:03:24,340
So again, let me clear this.

52
00:03:25,570 --> 00:03:28,810
OK, so the system knows how.

53
00:03:28,970 --> 00:03:33,550
Now let's see how to use export command with the function.

54
00:03:33,670 --> 00:03:37,810
OK, so as I have told you for using function you can use it like this.

55
00:03:38,140 --> 00:03:39,480
So this is the business index.

56
00:03:39,790 --> 00:03:41,770
So now see how you can do that.

57
00:03:42,070 --> 00:03:45,720
So what I'm going to do here is I'm going to create a function like name one.

58
00:03:46,270 --> 00:03:49,810
This is the basic syntax of function on inside this.

59
00:03:49,810 --> 00:03:53,820
I want to print on the screen with equal, OK, equal.

60
00:03:54,040 --> 00:03:56,710
Now I want to print here Lennix.

61
00:03:59,480 --> 00:04:00,720
So this is a Syntex.

62
00:04:01,160 --> 00:04:03,360
OK, now let's close this.

63
00:04:03,410 --> 00:04:05,360
So this is the basic index, not attender.

64
00:04:05,690 --> 00:04:11,620
So as you can see that what this is giving us, OK, system Nuyoricans, Inspector Tolkin.

65
00:04:11,930 --> 00:04:16,230
OK, so what it is doing here is there's a swinger's error.

66
00:04:16,520 --> 00:04:17,480
So now let's.

67
00:04:20,750 --> 00:04:21,890
Minimize, they say, the.

68
00:04:23,790 --> 00:04:25,070
What is the problem here?

69
00:04:25,170 --> 00:04:30,060
Let me do this night into as you can see, I need to add a space here.

70
00:04:30,270 --> 00:04:39,520
OK, so now it is working correctly now simply use export for function F so it will export the function

71
00:04:39,520 --> 00:04:40,220
now hit enter.

72
00:04:40,610 --> 00:04:41,490
OK, what.

73
00:04:42,030 --> 00:04:46,560
OK, the name of a function as like name one function.

74
00:04:46,590 --> 00:04:49,920
OK, let me change the name one night into.

75
00:04:50,340 --> 00:04:56,760
OK, so we are using Barth's to simplify Basia and then I want to see the content inside you, so I'm

76
00:04:56,760 --> 00:04:59,230
going to type the name of my function.

77
00:04:59,700 --> 00:05:03,270
So as you can see that Linnik scores that what we have given here.

78
00:05:03,300 --> 00:05:03,900
OK guys.

79
00:05:04,140 --> 00:05:07,260
So this is how you can use export for the function.

80
00:05:07,720 --> 00:05:08,500
Is this clear?

81
00:05:09,300 --> 00:05:11,900
So I think you get it what you want to.

82
00:05:12,090 --> 00:05:14,190
So you now simply let's see.

83
00:05:14,190 --> 00:05:15,540
First of all, clear this.

84
00:05:16,580 --> 00:05:17,930
First of all, clear this No.

85
00:05:19,510 --> 00:05:21,880
Let's see how we can create the function from beginning.

86
00:05:21,970 --> 00:05:24,100
OK, now let's see that how we can do that.

87
00:05:24,390 --> 00:05:29,950
OK, guys, for that simply type here, nothing but the function name, the function name like fun.

88
00:05:31,360 --> 00:05:34,660
Fun adding this not a big deal.

89
00:05:38,220 --> 00:05:41,070
Let me add the spaces here, Akko.

90
00:05:42,610 --> 00:05:45,250
On here, I want to give hello.

91
00:05:47,770 --> 00:05:56,380
Every one, OK, this is the way simply dominated, and so now we have created this function fun inside,

92
00:05:56,380 --> 00:05:58,330
which we are having haloed with.

93
00:05:58,900 --> 00:06:03,880
OK, so now let's see how you can do that simply type export for exporting it.

94
00:06:04,990 --> 00:06:10,240
Hyphen for function and name of the function, which is one I tend to be using best simplified best

95
00:06:10,420 --> 00:06:11,320
and then the function.

96
00:06:11,320 --> 00:06:15,190
And we just want anything to, as you can see that we are managed to get the result.

97
00:06:15,940 --> 00:06:17,730
What inside the function is.

98
00:06:17,860 --> 00:06:19,820
OK, so which is help everyone.

99
00:06:20,080 --> 00:06:21,850
Now guys, let's give this screen.

100
00:06:23,280 --> 00:06:29,160
And the thing that I'm going to do is I'm going to show you how to assign a value before exporting a

101
00:06:29,170 --> 00:06:30,510
function or a variable.

102
00:06:30,780 --> 00:06:36,990
OK, so now how you can do that assembly type is equal to fight like this and then simply export.

103
00:06:38,620 --> 00:06:43,250
Eight or okay, okay, okay, kill, simply not hit enter.

104
00:06:43,270 --> 00:06:50,590
So we have exported it and now we are going to use print E and we OK, so now.

105
00:06:51,010 --> 00:06:54,370
So what it will do, it was simply using this.

106
00:06:54,370 --> 00:06:59,070
We can verify the assignment by using the print e and we come on.

107
00:06:59,120 --> 00:07:02,900
OK, now enter software and as you can see that we are having to file.

108
00:07:03,520 --> 00:07:04,090
OK guys.

109
00:07:04,300 --> 00:07:07,600
So now let's see how to set them with a text editor.

110
00:07:07,900 --> 00:07:11,320
Now a text application with that we have inside the Linux.

111
00:07:12,590 --> 00:07:20,780
So now let's see now let's see how to set them as a default, Ed, so as we all know, the remote is

112
00:07:20,780 --> 00:07:27,320
the most widely used text editor for the Linux system, and we consider them as default text editor

113
00:07:27,320 --> 00:07:28,790
by using the export command.

114
00:07:28,810 --> 00:07:33,930
So for setting it now, let's see how you can set that simply type export.

115
00:07:34,220 --> 00:07:40,820
This is why exporting it, Ed Ed is spelling is right or not, or is this correct?

116
00:07:41,120 --> 00:07:42,000
Yes, this is correct.

117
00:07:42,020 --> 00:07:51,450
Now use this as the part this is a part of the way, Ed, which is the user, Ben and win.

118
00:07:51,590 --> 00:07:54,260
So if you want to see this, you can see it from here.

119
00:07:54,290 --> 00:08:01,640
OK, so now I'm not going to use this because I know this is the part now simply what you need to do.

120
00:08:01,640 --> 00:08:04,960
It is simply hit enter software and what you need to do.

121
00:08:05,420 --> 00:08:08,810
Next thing that is simply type export.

122
00:08:11,300 --> 00:08:14,210
With this unaccept.

123
00:08:15,970 --> 00:08:16,890
Ed.

124
00:08:16,930 --> 00:08:21,220
OK, so let me guess, planning is correct or not, because if it is.

125
00:08:22,500 --> 00:08:28,580
And you don't think it will give us an insight into so as you can see, that declared hyphenates ed

126
00:08:28,680 --> 00:08:30,030
exporters, Ed?

127
00:08:30,390 --> 00:08:37,720
That simply means that we have successfully managed to set the Weimar's of a default, Ed.

128
00:08:38,070 --> 00:08:43,320
So now let's see how to set an environmental variable so that we have seen earlier.

129
00:08:43,350 --> 00:08:44,400
So now let's see it again.

130
00:08:45,930 --> 00:08:47,580
Now, just clear this knowledge.

131
00:08:47,610 --> 00:08:49,180
See how you can do that.

132
00:08:49,530 --> 00:08:56,240
OK, so the syntax here will be very clear, like export, our name is equal to value.

133
00:08:56,250 --> 00:08:57,380
So this will be the same text.

134
00:08:57,420 --> 00:08:58,640
Now let's see how you can do that.

135
00:08:58,900 --> 00:09:05,220
So export we are going to use export now this as that language value to it is 50.

136
00:09:05,310 --> 00:09:08,250
Now I tend to simplified ecosystem and hit enter.

137
00:09:08,280 --> 00:09:11,900
You will see this says the name of the variable.

138
00:09:11,910 --> 00:09:14,870
Now if you want to see the content, what is the content inside it?

139
00:09:14,880 --> 00:09:19,740
Simply use equal percentage or so, not a dollar sign.

140
00:09:20,280 --> 00:09:24,930
So it will give you the value that what it contains inside it.

141
00:09:25,320 --> 00:09:31,230
OK, so this is how guys you can huze export come on inside Linux operating system.
