1
00:00:00,120 --> 00:00:04,920
OK, so now that we, you know, got past some of the basic command stuff, let's talk about scripting

2
00:00:05,040 --> 00:00:05,600
basics.

3
00:00:06,060 --> 00:00:11,510
So actually, actually the language that used to navigate Nesquik commands in Linux.

4
00:00:11,700 --> 00:00:17,370
So all of the demands that, you know, we've learned so far actually use the scripting with no modifications

5
00:00:17,370 --> 00:00:18,220
in them whatsoever.

6
00:00:18,540 --> 00:00:22,380
So congrats, because, you know, better scripting now.

7
00:00:23,190 --> 00:00:28,020
So all you need to do is use those commands as a basic knowledge of Basche syntax.

8
00:00:28,290 --> 00:00:32,370
And we're going to have the automating processes in no time like anything that we did.

9
00:00:32,400 --> 00:00:37,560
Now, you can literally do that with a through so you can open up your preferred editing application

10
00:00:37,830 --> 00:00:41,280
and, you know, get to work on some of the stuff that I'm about to show you right now.

11
00:00:41,790 --> 00:00:43,210
So here's the basics.

12
00:00:43,210 --> 00:00:49,950
So all backslaps typically start with this Paon in an exclamation point, slash slash bash, and that's

13
00:00:49,950 --> 00:00:52,010
at the top of the file.

14
00:00:52,100 --> 00:00:54,450
You're going to create an actual best script as a file.

15
00:00:54,720 --> 00:01:00,320
So you're going to want to make sure that this is at the top every time that you make a battlegroup.

16
00:01:00,600 --> 00:01:05,190
Dispersion tells the system what it's going to run this file with.

17
00:01:05,190 --> 00:01:08,460
But this could be slash being slash python or something.

18
00:01:08,460 --> 00:01:09,470
It was Python.

19
00:01:09,480 --> 00:01:10,950
But right now, who needs Basche?

20
00:01:10,950 --> 00:01:14,960
So that's what it's going to interpret all the following lines of code are as.

21
00:01:15,180 --> 00:01:19,170
And just remember that the fans are going to execute in the order that you put them in.

22
00:01:19,680 --> 00:01:24,690
If you want to declare it variable, you do the variable name equals and then your value.

23
00:01:25,470 --> 00:01:29,820
If you want to access it, you would just write a dollar sign followed by the variable name.

24
00:01:30,500 --> 00:01:37,200
If you want to print something out, you know, on the screen, you would just write Echo and then the

25
00:01:37,200 --> 00:01:41,090
parentheses and put your text in there or you echo and the new variable name.

26
00:01:41,100 --> 00:01:47,370
So let's go try some really great Lizzio, but a new file and V Basche practice.

27
00:01:47,400 --> 00:01:50,250
OK, so we're going to go on to answer mode.

28
00:01:50,700 --> 00:01:56,460
Remember we start close to the Palestine exclamation point, slash bean slash fast and now he knows

29
00:01:56,460 --> 00:01:58,350
to interpret this as a bad script.

30
00:01:58,830 --> 00:02:08,850
So we make a variable called this class and then we're going to be equals and we can do single quotes

31
00:02:08,850 --> 00:02:10,020
right here or double quotes.

32
00:02:10,200 --> 00:02:16,770
I want to say this class is super fun.

33
00:02:19,630 --> 00:02:25,060
And I'm going to tell my friends about it.

34
00:02:25,630 --> 00:02:28,540
There you go to make sure you do that.

35
00:02:29,740 --> 00:02:34,660
So now let's go down and let's actually access this variables.

36
00:02:34,670 --> 00:02:41,680
So echo dollar sign and then the variable names of this class.

37
00:02:42,250 --> 00:02:44,680
So now hit escape right quick.

38
00:02:45,370 --> 00:02:47,620
Bam, Alice.

39
00:02:48,220 --> 00:02:49,380
Now, what are you going to see?

40
00:02:49,380 --> 00:02:50,770
Is that the best practice?

41
00:02:51,070 --> 00:02:53,080
I actually does not have execution.

42
00:02:53,080 --> 00:02:53,230
Right.

43
00:02:53,260 --> 00:03:00,300
So what we can do is a mild shortcut, which would be Siegmund plus X and then the name of the file.

44
00:03:00,340 --> 00:03:01,820
Best practice, bam.

45
00:03:02,110 --> 00:03:05,820
And now the color changes and we have actually execution access.

46
00:03:06,070 --> 00:03:10,900
So the way that we can run this bash is done slash best practice.

47
00:03:12,340 --> 00:03:14,740
And hey, it echoed out.

48
00:03:15,220 --> 00:03:18,370
This class is super fun and I'm going to tell all my friends about it.

49
00:03:18,380 --> 00:03:20,650
So make sure that you guys do that right.

50
00:03:21,370 --> 00:03:23,650
So that's just like some basics in the syntax.

51
00:03:23,860 --> 00:03:25,920
So now let's go over functions in bash.

52
00:03:26,320 --> 00:03:30,220
So to create a function and bash, it's going to look like this.

53
00:03:30,220 --> 00:03:35,770
You had the function name and then two parentheses and then these curly braces and then you put your

54
00:03:35,770 --> 00:03:39,550
commands for the function inside of it and all the function.

55
00:03:39,790 --> 00:03:41,280
You just type the function name.

56
00:03:41,330 --> 00:03:42,560
It'll do the function.

57
00:03:44,020 --> 00:03:50,140
So if you want to create a function that takes in an argument from the command line, so you just get

58
00:03:50,140 --> 00:03:53,990
the function name again and then echo.

59
00:03:54,460 --> 00:03:55,930
So here we have Echo.

60
00:03:55,960 --> 00:04:04,460
This is the random number today is and then it has signed one so that on one sets the argument given

61
00:04:04,460 --> 00:04:06,490
that the command line to that variable.

62
00:04:06,490 --> 00:04:06,650
Right.

63
00:04:06,820 --> 00:04:12,580
So whatever the first argument that you input at the command line after you put dot slash and then the

64
00:04:12,580 --> 00:04:19,120
filename and the space and maybe you type in something else, like you type in like a random number,

65
00:04:19,120 --> 00:04:22,900
it would actually use that as the variable.

66
00:04:23,080 --> 00:04:30,670
And we can you for this one specifically, we could just use the random variable which is in Gibby and

67
00:04:30,670 --> 00:04:33,650
Linux by default, and you'll be able to just pass on a random number.

68
00:04:33,680 --> 00:04:36,510
So let's actually go and try to make this OK.

69
00:04:36,520 --> 00:04:40,600
So I'm just starting to follow the bash function.

70
00:04:43,950 --> 00:04:50,560
So remember, we have to start with the policy points has been bash and then we can go down.

71
00:04:50,580 --> 00:04:56,010
So I don't want to do as going to set a variable equal to our first argument that we're going to pass

72
00:04:56,100 --> 00:04:56,370
in.

73
00:04:56,730 --> 00:05:03,280
So numbers that equal time once and now, the name of our function, which would be pass argument,

74
00:05:03,300 --> 00:05:07,470
I say that parentheses and curly braces.

75
00:05:07,740 --> 00:05:17,940
So now say echo today's user provided no is

76
00:05:20,280 --> 00:05:24,390
and then you can put no.

77
00:05:24,660 --> 00:05:25,320
There we go.

78
00:05:25,470 --> 00:05:26,020
Right there.

79
00:05:26,760 --> 00:05:29,760
So Cityscape quit.

80
00:05:30,600 --> 00:05:31,430
Well actually sorry.

81
00:05:31,680 --> 00:05:36,940
Before we do that, of course we have to call the function which makes sense.

82
00:05:37,320 --> 00:05:39,420
So let's go ahead and call the function.

83
00:05:39,630 --> 00:05:48,060
So pass argument is all you have to do is makes quit, give execution access.

84
00:05:48,480 --> 00:05:54,230
Sejima plus Xpress function there.

85
00:05:54,490 --> 00:06:01,980
Oh so dot slash function and let's say seventy six five for every go.

86
00:06:02,230 --> 00:06:05,470
Today's provision provider number is seven six five four.

87
00:06:05,640 --> 00:06:08,940
So now you know kind of like the basis of creating a functioning Basche.

88
00:06:09,140 --> 00:06:12,570
OK, so now let's go over capturing user input.

89
00:06:12,810 --> 00:06:19,980
So the input from user and stored as a variable we would use the Grand Redzepi, whatever text you want

90
00:06:19,980 --> 00:06:26,850
to print out, and then a variable name and read input from user solidly from passwords stored is variable.

91
00:06:27,060 --> 00:06:29,250
You would say redoes Espie.

92
00:06:29,430 --> 00:06:33,270
They need this X you wanted to print out and then followed by the the variable name.

93
00:06:33,840 --> 00:06:35,910
OK, so now let's go try this out really quickly.

94
00:06:36,030 --> 00:06:39,830
OK, so I'm going to start a new file, the C v input.

95
00:06:40,080 --> 00:06:40,710
Keep it simple.

96
00:06:41,040 --> 00:06:46,210
So let's put our command here first slash bash.

97
00:06:47,400 --> 00:06:59,610
So now let's do read the SPI username, keep the symbol and per user as the variable when a star dies

98
00:06:59,610 --> 00:07:07,930
and read Espie password pass W.D..

99
00:07:08,670 --> 00:07:12,650
So now we have we can echo these because the story's variables now.

100
00:07:12,660 --> 00:07:16,290
So let's say now this echo, you know.

101
00:07:17,010 --> 00:07:17,910
Thanks.

102
00:07:19,880 --> 00:07:30,700
Or say thanks and then username, so say thanks, user, your password is now password.

103
00:07:30,740 --> 00:07:43,690
There you see my plus X and puts type wrong sige plus X inputs.

104
00:07:44,450 --> 00:07:46,130
Got such input.

105
00:07:47,450 --> 00:07:48,770
Not as from your username.

106
00:07:48,770 --> 00:07:51,080
So Anthony password.

107
00:07:51,800 --> 00:07:52,560
Password.

108
00:07:53,870 --> 00:07:54,710
Thanks Anthony.

109
00:07:54,770 --> 00:07:59,270
Your password is not password they so now you're not taking user input.

110
00:07:59,630 --> 00:08:04,580
And I'm just going to give you guys an example of, you know, a conditional statement in Basche really

111
00:08:04,580 --> 00:08:05,060
quickly.

112
00:08:05,450 --> 00:08:10,250
So when you see, you know, dash alti that means less then.

113
00:08:10,250 --> 00:08:13,800
And then if you see Dash G.T., that means greater than.

114
00:08:13,820 --> 00:08:15,890
So this one is asking you.

115
00:08:15,890 --> 00:08:18,260
So it takes your input, ask you how old you are.

116
00:08:18,350 --> 00:08:19,220
So what's your age?

117
00:08:19,610 --> 00:08:27,890
And then it says if the variable age is less than 16, then you're going to echo you are young or else

118
00:08:27,890 --> 00:08:30,740
if which is like saying like another if statement.

119
00:08:31,010 --> 00:08:36,010
If the age is greater than 60, we're going to say, hey, we're going to print out your mature.

120
00:08:36,440 --> 00:08:42,170
Other than that, we're going to go out, you're in the middle and then fee and the additional.

121
00:08:42,620 --> 00:08:46,100
OK, so that's like, you know, kind of basic of that.

122
00:08:46,220 --> 00:08:51,230
So and that's, you know, Basche kind of in a in a nutshell, you know, it's a lot of conditional

123
00:08:51,230 --> 00:08:56,870
statements and just using a different syntax and commands to execute things that you want to do this,

124
00:08:56,900 --> 00:09:00,410
it can go a lot deeper than we did and you can go out and learn that on your own.

125
00:09:00,410 --> 00:09:02,320
But that's pretty much the basics of Vash.
