WEBVTT 00:08.730 --> 00:12.600 Holder in this lesson you're going to talk about the garbage. 00:12.670 --> 00:14.600 And by being in Linux. 00:14.630 --> 00:15.100 OK. 00:15.200 --> 00:17.870 So talk about the come on with that action. 00:18.240 --> 00:26.460 So what is on with that action in Linux and meant any command that we execute is having three streams 00:26.460 --> 00:27.650 connected to it. 00:27.720 --> 00:28.580 OK. 00:28.590 --> 00:37.210 And those streams are standard input stream standard output stream and standard errors every day. 00:37.500 --> 00:44.250 With the help of these teams we can connect to the come on OK and we can either sell the data from it 00:44.250 --> 00:50.190 come on to a file or send the data as in who to come on from will find. 00:50.470 --> 00:50.740 OK. 00:50.740 --> 00:53.480 In short saving the out of. 00:53.540 --> 00:54.340 Come on. 00:54.410 --> 00:57.950 Go fly or sending in poop. 00:57.960 --> 00:58.530 Come on. 00:58.550 --> 01:01.660 Well fly is calling us come on the direction. 01:01.800 --> 01:07.050 And this country that actually needs the help of some operators. 01:07.080 --> 01:09.230 OK so let's see practically. 01:09.300 --> 01:13.980 How good is it first of all I would like to show you a new. 01:13.980 --> 01:15.020 Come on. 01:15.290 --> 01:15.590 OK. 01:15.600 --> 01:17.900 Which is used to create any kind of fine. 01:18.050 --> 01:20.800 Come on it's touch. 01:21.270 --> 01:24.020 That's Come on you can create any kind of file. 01:24.210 --> 01:24.770 OK. 01:25.080 --> 01:32.410 So suppose I want to create start the dx d and d h dot theory of file. 01:32.660 --> 01:37.780 And he turned to look at those files are they created in the current directory. 01:37.810 --> 01:44.510 LS And here you can see as you don't believe and dirty as stiff fines are created here. 01:44.600 --> 01:44.920 OK. 01:45.020 --> 01:49.530 And already there are some folders and files are present with that POV. 01:49.560 --> 01:52.490 But come on you can create any kind of file. 01:52.600 --> 01:52.990 OK. 01:53.130 --> 01:56.880 So let's talk about the Kamandi that action. 01:56.970 --> 02:01.260 So now we are going to search the output often come on file. 02:01.470 --> 02:06.720 Ok let's try this with Derleth's come on if you want to see the output of the Silis come on. 02:06.720 --> 02:07.790 Go find them. 02:07.790 --> 02:13.170 Just type in less space rather than operator and the name of the file. 02:13.290 --> 02:15.450 Very want to see the data. 02:15.450 --> 02:18.460 Suppose I type it Dorothy XTi and hit enter. 02:18.680 --> 02:19.180 OK. 02:19.350 --> 02:23.240 So you can see the come on does not show any output. 02:23.280 --> 02:27.760 And there are all these directly so to the file they're not the XP. 02:27.850 --> 02:28.510 Let's see. 02:28.560 --> 02:34.290 Got 60 and here you can see the output of this command is so good it's fine. 02:34.500 --> 02:35.060 OK. 02:35.220 --> 02:40.830 In this way greater great golden is used to seal the output of the come on. 02:41.060 --> 02:43.380 We'll find the next operator. 02:43.530 --> 02:49.750 That I would like to show you here is the greater than greater than OPERATOR OK rather than greater 02:49.760 --> 02:53.040 than operator is rendered like this. 02:53.120 --> 02:59.700 OK but before I actually show you let's try the same come on again here. 02:59.910 --> 03:04.690 And let's see the contents of it got the key fine. 03:04.850 --> 03:05.260 OK. 03:05.280 --> 03:11.900 You can see here the exit Kuper the same Come on times but determined the same. 03:11.900 --> 03:16.530 That means the same output should be added twice here. 03:16.650 --> 03:21.220 But instead of that it is showing the output only one time here. 03:21.350 --> 03:21.780 OK. 03:21.900 --> 03:31.140 So why this thing is happening because every time when you use this operator it it is all the previous 03:31.380 --> 03:35.480 contents of the file and add the new content stupid. 03:35.780 --> 03:40.640 OK so our this problem is greater than greater than our credit is. 03:40.680 --> 03:47.640 Again this will open the output to the already existing file without it is in the data. 03:47.790 --> 03:49.680 OK so let's try it. 03:50.160 --> 03:50.650 OK. 03:50.650 --> 03:55.120 And now let's do the contents of the XTi. 03:55.650 --> 03:59.040 And now here you can see the data is appended. 03:59.060 --> 03:59.410 OK. 03:59.410 --> 04:06.150 Now we can see here the same data two times in this way you can use the greater then greater than Obregon 04:06.680 --> 04:08.890 up in the data file. 04:09.130 --> 04:09.810 OK. 04:09.900 --> 04:14.680 Now I show you Hoku sin there better from will file as input. 04:14.820 --> 04:15.670 Come on. 04:15.930 --> 04:19.970 OK so the someone is used to store the data OK from a fine. 04:20.100 --> 04:20.550 OK. 04:20.640 --> 04:23.130 So you send the input sort. 04:23.130 --> 04:30.000 Come on from this file you need to use the operator like this or get sort less done operator and the 04:30.120 --> 04:32.360 filing that is it not BSD. 04:32.440 --> 04:34.170 Let's see what happens. 04:34.680 --> 04:34.980 OK. 04:34.980 --> 04:38.960 Here you can see it's sort of present inside the file. 04:39.150 --> 04:40.290 OK. 04:40.290 --> 04:49.720 And if you want to sort the data in the was order just provide the option here to slash R and hit enter. 04:49.920 --> 04:54.890 And here you can see it displays or it's sort the data in the reverse order. 04:54.930 --> 04:55.300 OK. 04:55.320 --> 04:56.530 From the file. 04:56.760 --> 05:03.460 In this way you can send the input to come on from all file with the help of less than praeter. 05:03.610 --> 05:04.140 OK. 05:04.380 --> 05:13.440 In this way does come on a redirection or use the piggy to send Darco file or receive the data from 05:13.440 --> 05:14.390 a fine. 05:14.760 --> 05:15.070 OK. 05:15.090 --> 05:21.810 Now here you saw how the data is sorted there with the help of this operator board how to check whether 05:21.920 --> 05:24.190 your command is working or not. 05:24.250 --> 05:24.890 OK. 05:25.110 --> 05:31.020 Because when you remove those and hit enter it will show the same output. 05:31.710 --> 05:35.750 So we can take this by combining two operators here. 05:36.080 --> 05:36.630 OK. 05:36.840 --> 05:39.710 Both less than and greater than that means. 05:39.710 --> 05:45.680 Here we are sorting the data entry was order and serving it to new file that is. 05:45.710 --> 05:48.030 Tony got The X Files. 05:48.080 --> 05:50.420 OK let's see what happens. 05:50.700 --> 05:51.400 OK. 05:52.200 --> 05:53.360 And here we go. 05:53.550 --> 05:55.040 The file is created. 05:55.320 --> 05:57.100 Give you the contents 06:00.120 --> 06:00.510 again. 06:00.510 --> 06:05.550 Here you can see the data is so good that there will not be any file in reverse order. 06:05.690 --> 06:06.000 OK. 06:06.000 --> 06:07.490 That means our. 06:07.550 --> 06:11.060 Come on our code here is working OK. 06:11.120 --> 06:14.700 The next thing that I would like to explain here is piping. 06:14.700 --> 06:19.890 So what is piping piping means sending out to go from one come on. 06:19.890 --> 06:21.130 As in put on a. 06:21.150 --> 06:21.900 Come on. 06:22.110 --> 06:22.560 OK. 06:22.740 --> 06:28.890 And we can accomplish this video of pipe operator here we can see the pipe operator is denoted by the 06:28.890 --> 06:30.950 symbol here on your keyboard. 06:32.120 --> 06:38.040 OK let's do the piping with the same Come on less and the pipe OPERATOR OK. 06:38.080 --> 06:38.770 Ellis come on. 06:38.770 --> 06:40.800 We displayed the files and folders. 06:40.810 --> 06:41.390 OK. 06:41.640 --> 06:44.860 And I want to sort it and display it to the output. 06:44.890 --> 06:47.170 So let's use the sort. 06:47.260 --> 06:50.700 On and I want to sort them in reverse order. 06:50.700 --> 06:54.060 So last hour let's see what happens. 06:54.490 --> 06:55.180 OK. 06:55.180 --> 06:59.880 Here you can see the output of ls come on send it to the sot. 06:59.890 --> 07:00.300 Come on. 07:00.310 --> 07:05.690 And the command will sort the data and display them or put. 07:05.740 --> 07:09.910 And what happens if I remove the slasher printer. 07:09.970 --> 07:14.930 And here you can see it sort the data in the ascending order. 07:15.190 --> 07:23.030 So in this way you can use Kamandi direction and piping it to seal the data or to send the input to 07:23.030 --> 07:26.940 a command from a file or to send out go go. 07:26.950 --> 07:27.790 Come on that's it. 07:27.820 --> 07:28.800 Put the on. 07:28.840 --> 07:29.530 Come on. 07:29.680 --> 07:30.220 OK.
