1 00:00:00,120 --> 00:00:03,480 OK, now it's time to talk about the loops in script. 2 00:00:04,530 --> 00:00:06,810 Now, let's talk with the for loop. 3 00:00:07,140 --> 00:00:11,220 So, Vin, as datasets that we created previously know here. 4 00:00:11,490 --> 00:00:16,270 So this index is like that for the variable, which is I in. 5 00:00:16,740 --> 00:00:18,540 And then what the sequence? 6 00:00:18,900 --> 00:00:24,960 So for example, I use the braces like that and I looked in double quotation one. 7 00:00:26,040 --> 00:00:28,440 And Coma to arrest the. 8 00:00:29,960 --> 00:00:37,640 And three, OK, now do put the command you want, for example, Brent I. 9 00:00:39,610 --> 00:00:42,820 Then done, OK, so it is like that. 10 00:00:43,210 --> 00:00:47,250 For I in this sequence, dun dun dun. 11 00:00:47,440 --> 00:00:51,790 And inside it's equal the eye, so it will bring it on to three. 12 00:00:53,460 --> 00:00:54,050 No, listen. 13 00:00:54,390 --> 00:00:57,210 That's the test that you can see that is one to three. 14 00:00:57,660 --> 00:00:58,460 All right, cool. 15 00:00:59,100 --> 00:01:02,380 Now we can have a sequence and read from a fight. 16 00:01:02,400 --> 00:01:10,750 So for example, let's touch, let's do test, OK, and let's list the text and inside it. 17 00:01:10,750 --> 00:01:15,400 Let me put first one or two there. 18 00:01:16,760 --> 00:01:18,960 Values, blah blah blah. 19 00:01:19,140 --> 00:01:20,990 OK, whatever. 20 00:01:21,830 --> 00:01:26,390 Now here inside the US as edge, this time I want to bring this fight. 21 00:01:26,750 --> 00:01:30,620 But how did we learn to put undone? 22 00:01:31,720 --> 00:01:33,700 A comment inside the bash script. 23 00:01:34,210 --> 00:01:34,930 Yes, you are right. 24 00:01:34,960 --> 00:01:40,270 Using either that back quotation like that or the dollar sign with Beckett's. 25 00:01:40,780 --> 00:01:48,610 Let's put that quotation back single quotation and let's put cat, let's do text and then it's equal 26 00:01:48,610 --> 00:01:49,000 AI. 27 00:01:49,330 --> 00:01:50,800 So let's run, as did. 28 00:01:51,240 --> 00:01:55,900 Yeah, you can see that it will be first to third in the value of the fight. 29 00:01:58,290 --> 00:01:59,280 Also, we can have. 30 00:02:01,150 --> 00:02:07,300 Practical usage, like we want to bring a range of IP addresses so forth. 31 00:02:07,540 --> 00:02:12,880 Let's put this from one notes and then walked in. 32 00:02:13,210 --> 00:02:15,040 OK, now here echo. 33 00:02:15,670 --> 00:02:23,140 One two nine eight one six eight zero Dot the I and I. 34 00:02:23,170 --> 00:02:28,180 It's been one to three until we reached an OK, so let's hit and run to see what the values. 35 00:02:28,390 --> 00:02:29,110 You can see that. 36 00:02:29,140 --> 00:02:31,330 One two three four until we reach 10. 37 00:02:31,660 --> 00:02:35,740 OK, so this is a practical example to generate ideas, for example. 38 00:02:36,430 --> 00:02:38,230 OK, now this is for the poor. 39 00:02:38,530 --> 00:02:42,080 Now we have another syntax for the loops, which is the way loops. 40 00:02:42,130 --> 00:02:42,610 OK? 41 00:02:43,120 --> 00:02:46,480 Just as the programming languages, by the way, it is the same. 42 00:02:47,110 --> 00:02:48,310 So let's delete this. 43 00:02:49,600 --> 00:02:54,100 The syntax is like that while then put inside a brackets. 44 00:02:54,340 --> 00:02:59,410 Make sure the two follow as we learned from the events there as a spaces between here. 45 00:02:59,980 --> 00:03:04,360 OK, now here we can put that wild thing. 46 00:03:04,450 --> 00:03:04,870 OK. 47 00:03:04,900 --> 00:03:08,680 First, let's put out that this is just an example equal one. 48 00:03:09,310 --> 00:03:09,880 Or let's. 49 00:03:10,460 --> 00:03:12,040 But that's OK. 50 00:03:12,040 --> 00:03:19,420 Now that there are same counter is dexterity, which means less than 10, for example. 51 00:03:19,660 --> 00:03:22,840 And Mitchell, there is a spaces, then we will do. 52 00:03:22,990 --> 00:03:29,140 And after we finished done and inside the y loop, we want to equal, for example. 53 00:03:30,700 --> 00:03:31,420 The count up. 54 00:03:32,720 --> 00:03:33,200 OK. 55 00:03:33,500 --> 00:03:41,900 And after we bring the count up, we can use this command, which is putting two double brackets count 56 00:03:43,040 --> 00:03:44,900 plus plus like that. 57 00:03:45,410 --> 00:03:47,960 So this will increase the counter. 58 00:03:48,350 --> 00:03:55,600 Let's on it and you can see it will start showing one two three until we reach nine and 10 is not included 59 00:03:55,600 --> 00:03:56,330 it to include it. 60 00:03:56,570 --> 00:03:57,860 Actually, it's not less. 61 00:03:57,860 --> 00:04:00,000 Then it's less or equal. 62 00:04:00,050 --> 00:04:00,870 So, Ellie?
