WEBVTT 00:09.500 --> 00:11.830 Friends will come back in this lesson. 00:11.840 --> 00:16.540 We're going to talk about Mount human and Polmar mountain in Linux. 00:16.570 --> 00:17.140 OK. 00:17.210 --> 00:24.070 In our previous lesson we learn how to create partition and how to install a file system on it. 00:24.260 --> 00:28.830 But creating partitions and installing the file system is not enough. 00:28.850 --> 00:32.840 You need to mount those devices for or partition somewhere. 00:32.900 --> 00:41.370 OK on your Linux system and only after that you can access that for creating file or storing any data. 00:41.700 --> 00:44.460 Soft unmounting these devices are partitions. 00:44.480 --> 00:47.950 You can easily access them for storing the data. 00:48.130 --> 00:52.340 OK so let's see here practically how to do this. 00:52.680 --> 00:53.280 OK. 00:53.390 --> 00:58.710 In the Linux environment there are two folders which are dedicated for mounting. 00:58.730 --> 01:01.890 OK so let's get inside room and Alice. 01:01.940 --> 01:08.900 And here you can see mehndi is a folder or directory which is generally used for mounting any type of 01:08.900 --> 01:09.540 device. 01:09.560 --> 01:17.210 OK you can mount here inside this directory and media is reserved for mounting the CD or DVD type of 01:17.210 --> 01:18.250 devices. 01:18.310 --> 01:22.730 OK so here we have created the partitions. 01:22.750 --> 01:28.270 OK let's get to this. 01:28.950 --> 01:32.920 OK we are hiring as TB One two three and five. 01:33.340 --> 01:39.020 OK here I want to mount as D-B one device good directory student. 01:39.220 --> 01:43.090 OK Rich I'm going to create a now inside the empty directory. 01:43.270 --> 01:48.760 OK so what you need to do to mount on this partition or this device. 01:49.060 --> 01:57.210 So first of all let's get inside Amanti OK here there is no file folder present here. 01:57.220 --> 02:01.340 So create a directory regear student. 02:01.360 --> 02:08.420 Suppose I have some student data and I want to store that data on this as DBI one. 02:08.500 --> 02:12.230 OK so it says a permission denied. 02:14.120 --> 02:24.110 Sudol know Alice OK first of all good inside the student Alice OK here you can see there is no file 02:24.240 --> 02:25.780 or for the present. 02:25.990 --> 02:26.710 OK. 02:27.290 --> 02:35.840 So you mount over as D-B one do this directly what you need to do is go slow one called pseudo then 02:35.870 --> 02:37.460 type the command mount. 02:37.730 --> 02:43.790 Ok then here you need to Florida twice that is do as we want. 02:44.150 --> 02:47.440 And here you need to provide very one command. 02:47.450 --> 02:51.750 So here I want to in Amandeep student. 02:51.860 --> 02:53.220 Get Hit enter. 02:53.450 --> 02:55.580 OK this come on executor's successfully. 02:55.580 --> 02:57.540 Now let's get inside. 02:57.860 --> 03:01.330 And then the student and Alice. 03:01.370 --> 03:09.230 And here you can see after mounting the device or partition here the last phone folder is get graded 03:09.230 --> 03:10.270 ecumenically. 03:10.450 --> 03:10.940 OK. 03:11.030 --> 03:18.020 Now we can't access or now we are accessing actually on that device so I want to create the directory 03:18.020 --> 03:23.440 here the SuBo access. 03:24.040 --> 03:30.980 OK now all these directories get created or you can create a file like this. 03:33.640 --> 03:39.350 In this way you can mount a device OK to store the data. 03:39.400 --> 03:39.880 OK. 03:39.990 --> 03:43.220 And you can create different partitions according to a need. 03:43.260 --> 03:50.010 That means I suppose you want to store all your audio files on a particular partition then you can name 03:50.010 --> 03:50.570 it as. 03:50.580 --> 03:56.550 Or do you read you like that or particularly does it's depend on your requirement. 03:56.550 --> 03:57.130 OK. 03:57.570 --> 04:02.220 So there are some situations where you need to unmount the device. 04:02.280 --> 04:06.800 So we currently monitor the device to this directly steward. 04:06.960 --> 04:12.240 So Hoku an mounted device and monitor device you need to type you. 04:13.040 --> 04:17.600 And I say name has to be one and hit enter. 04:18.030 --> 04:18.530 OK. 04:18.540 --> 04:28.960 Now let's get inside this and then directly student Alice and here you can see we can order one for 04:28.960 --> 04:29.100 you. 04:29.110 --> 04:33.400 And one final word there is no file and folder is present here. 04:33.400 --> 04:36.350 That means there do I see them successfully. 04:36.490 --> 04:37.190 OK. 04:37.750 --> 04:44.410 You can mount and mount the devices in the Linux environment but there is a problem in this technique. 04:44.410 --> 04:50.700 The problem is that when you restart your system then the machine to do this or get unmounted or go 04:50.720 --> 04:51.470 magically. 04:51.700 --> 04:52.150 OK. 04:52.360 --> 04:54.350 So how to avoid this problem. 04:54.480 --> 04:54.810 OK. 04:54.820 --> 04:59.490 So there is over two hours this problem the raise permanent mounting. 04:59.650 --> 05:06.730 So to permanently mounted device what you need to do is unique plus add some information inside the 05:06.730 --> 05:10.720 f stop file which is present in the EDC directory. 05:10.790 --> 05:11.280 OK. 05:11.440 --> 05:13.730 So let's see that break here. 05:13.780 --> 05:17.650 And you need to have root access to that file. 05:17.710 --> 05:21.550 So switches are the root now. 05:22.130 --> 05:27.880 So let's see the contents of that file which is present in the EDC of a step. 05:27.880 --> 05:30.570 So for exercising that stuff. 05:30.580 --> 05:39.460 Why didn't we see a step Okay now we are inside this fine. 05:39.730 --> 05:40.510 OK. 05:40.570 --> 05:46.860 This file contains the information about the devices and the different devices. 05:46.930 --> 05:49.090 So let's see what information presented here. 05:49.090 --> 05:53.310 So let's talk about these columns which are present here one by one. 05:53.370 --> 05:58.540 OK the first column represents the device the device that you want to mount. 05:58.710 --> 05:59.130 OK. 05:59.230 --> 06:08.830 Here you can mount the devices with the device ID that is you ID OK or the part that is forwards less 06:08.880 --> 06:12.980 deal or will slash as did one as Dibbell do like that. 06:13.000 --> 06:13.380 OK. 06:13.390 --> 06:16.210 There are two ways to mount the device. 06:16.540 --> 06:20.540 And the next column here is talk about the mount point. 06:20.590 --> 06:27.880 You need to specify where you want to mount that device so here you can see the boot option is displayed 06:27.880 --> 06:28.340 here. 06:28.390 --> 06:32.050 For this you ID it be too easy. 06:32.080 --> 06:32.600 OK. 06:32.710 --> 06:41.200 And after that the next thing you type here you need to specify the file system type ok that you already 06:41.320 --> 06:44.970 created for that device or the device is already harrying. 06:45.100 --> 06:47.440 You need to specify that type here. 06:47.580 --> 06:49.600 And after that there is no option. 06:49.750 --> 06:50.170 OK. 06:50.260 --> 06:55.980 Here in this column we need to specify the options so there are different kinds of options like seeing 06:56.250 --> 06:56.820 things. 06:56.930 --> 07:07.120 Ok but here I would like to suggest that you need to set this default so it takes the right choice OK 07:07.300 --> 07:08.660 for your device. 07:08.920 --> 07:11.970 So set it to default the next column. 07:11.980 --> 07:13.890 Talks about the dumb support. 07:14.140 --> 07:15.660 So what is dumb support. 07:15.760 --> 07:22.390 When you said this to one so it will automatically back up your device. 07:22.390 --> 07:22.910 OK. 07:23.020 --> 07:25.360 So that is the dumb support. 07:25.570 --> 07:30.260 So when you said to do one that means it is true and it will back up the device. 07:30.280 --> 07:36.730 And when you set it to zero that means this device does not want the don't support and the last column 07:36.770 --> 07:39.840 talks about the first seek support. 07:40.000 --> 07:42.250 OK so what does support is. 07:42.260 --> 07:49.870 So it will check the file system at boot time for any errors if it found the error then it will automatically 07:49.870 --> 07:51.800 repair from that era. 07:52.000 --> 07:52.340 OK. 07:52.360 --> 07:59.680 So here one is reserved for a root file system and for other file systems you need to specify a number 07:59.680 --> 08:00.130 two. 08:00.200 --> 08:00.700 OK. 08:00.910 --> 08:05.220 And if you don't want this support then you can set it by zero. 08:05.410 --> 08:06.080 OK. 08:06.280 --> 08:10.920 So in this way this information is present here and you need to specify. 08:11.320 --> 08:14.690 So here first of all this fine. 08:15.220 --> 08:17.310 And I want to mount is the big one. 08:17.380 --> 08:17.900 OK. 08:17.980 --> 08:28.260 So first of all we need these you I.D. So how to get that get the you Id just type Id come on now. 08:28.360 --> 08:31.420 They show us all the eyes and their needs. 08:31.420 --> 08:34.370 So this did this data argufying 08:36.860 --> 08:38.380 student. 08:38.950 --> 08:43.380 Now this is why Ed.. 08:44.340 --> 08:44.890 OK. 08:45.250 --> 08:48.700 So we need as D-B one device ID. 08:48.760 --> 08:49.130 OK. 08:49.150 --> 08:57.470 So gresse control V and then with arrow keys you can select these ID cannot press y y on your keyboard. 08:57.640 --> 09:04.370 OK then could this file now open the stuff file. 09:04.650 --> 09:09.020 Why didn't you see this. 09:10.540 --> 09:11.250 OK. 09:11.640 --> 09:20.080 At this point Chris we now getting insert more so press I remove this code. 09:20.950 --> 09:21.520 OK. 09:21.630 --> 09:22.800 Now the how. 09:23.030 --> 09:28.230 Specify here this device ID then you specify the mount point. 09:28.260 --> 09:32.240 So I want to mount it inside and then student. 09:32.720 --> 09:33.400 OK. 09:33.450 --> 09:42.460 And this device is having the file system the XTi for and this option set to defaults the of the yes 09:42.600 --> 09:43.980 defaults. 09:44.400 --> 09:50.760 And I wanted the don't support so it to one and I don't want any of this to give said zero. 09:50.850 --> 09:51.390 OK. 09:51.630 --> 09:58.080 In this way you can add this information a permanently mounted device or you can also mount the device 09:58.140 --> 09:59.440 with this real life. 09:59.530 --> 10:01.170 There is TV too. 10:01.280 --> 10:01.830 OK. 10:01.980 --> 10:02.400 It is. 10:02.400 --> 10:11.600 What do I do instead of this idea of we can use this technique so now I write this content. 10:12.600 --> 10:13.000 OK. 10:13.020 --> 10:17.170 The data is returned to these files so you can take it with CAD. 10:17.550 --> 10:20.030 If you see that. 10:20.620 --> 10:20.970 OK. 10:20.970 --> 10:24.650 Here you can see our data is added inside this file. 10:24.930 --> 10:29.760 So Oscar adding this you need to upgrade this stuff file. 10:29.880 --> 10:30.490 OK. 10:30.660 --> 10:38.500 So for that this type mountain a will at pneumatically mount the devices under this fight. 10:38.580 --> 10:39.050 OK. 10:39.240 --> 10:46.710 So now we have mounted the STV One permanently means when our computer really starts Dooku this file 10:46.740 --> 10:49.410 our device is set to do more. 10:49.600 --> 10:50.020 OK. 10:50.090 --> 10:55.290 So it is monitored or not get inside a CD. 10:55.540 --> 10:58.550 Mandy to Alice. 10:58.710 --> 11:02.760 And here you can see we got our files back here. 11:02.940 --> 11:08.680 So in this way you can go the mounted device with the help of this technique.
