WEBVTT 00:09.190 --> 00:10.720 Hello Friends Welcome back. 00:10.720 --> 00:17.140 Welcome to this Manitobans section in this whole section we're going to talk about the disk management 00:17.140 --> 00:18.030 utilities. 00:18.040 --> 00:18.430 OK. 00:18.550 --> 00:23.980 So in this lesson we're going to talk about how could this be serious. 00:23.980 --> 00:26.480 OK we're going to learn how to do this. 00:26.490 --> 00:28.280 This just in this lesson. 00:28.570 --> 00:36.550 So there are two commands that is defined you which we can use to see that this is available on your 00:36.550 --> 00:39.070 system to get selected practically. 00:39.090 --> 00:40.390 Goodness. 00:40.390 --> 00:45.730 So to take that this you just just type D.S. and I don't know. 00:45.760 --> 00:49.330 It reduces this information in this format. 00:49.380 --> 00:49.920 OK. 00:50.170 --> 00:51.710 So let's see it one by one. 00:51.880 --> 00:57.030 OK the first column was the information about the storage devices. 00:57.520 --> 01:00.090 And this column is named as file system. 01:00.130 --> 01:04.020 So here you can see there is the one it is a storage device. 01:04.060 --> 01:04.560 OK. 01:04.660 --> 01:11.380 There are different stores locations here in say we can see here these storage devices are the storage 01:11.380 --> 01:12.240 locations. 01:12.460 --> 01:19.390 And after that the next column shows us the total amount of memory available for as one you can see 01:19.390 --> 01:25.790 here for eight to nine good to get is the total amount of space available. 01:25.810 --> 01:32.530 And it is in kilobytes and the next column shows us the use of the memory out of this total available 01:32.530 --> 01:37.540 memory that is 5 9 5 2 5 month memory used. 01:37.750 --> 01:43.210 And the next column shows us the available memory out of this total available memory. 01:43.250 --> 01:43.680 OK. 01:43.840 --> 01:47.900 So 3 9 8 4 3 it is the available memory. 01:47.970 --> 01:50.870 I'll go for it to 9 2 to. 01:51.280 --> 01:57.450 And the next column shows us the memory in percentage of memory users percentage. 01:57.640 --> 02:05.620 So here you can see 13 percent of memory is used by the out of total available memory and the last column 02:05.620 --> 02:14.170 shows us the mumping location where these devices are mounted in Linux operating system every device 02:14.200 --> 02:17.160 you connect is to recognize it as a file. 02:17.350 --> 02:21.530 And if you want to access that device you need to mount that somewhere. 02:21.680 --> 02:22.090 OK. 02:22.210 --> 02:28.960 So in our upcoming lessons we can learn about it in detail how to mount the device. 02:29.350 --> 02:33.350 Suppose you have a pen drive and if you want to see the contents you need to mount it. 02:33.400 --> 02:38.470 So these are the mounting locations of various devices. 02:38.770 --> 02:45.100 So in this way we could understand these things but there is one problem of when we see these memory 02:45.100 --> 02:50.430 users or memory Well we can't understand what exactly you want to see. 02:50.710 --> 02:56.550 So if you want to understand this in human readable form disprove it is switch edge. 02:56.590 --> 03:04.330 Now here you can see it shows the information in Megabytes as dear one is currently having four hundred 03:04.330 --> 03:11.950 seventy megabyte of memory and of that only 59 megabytes is used Dantley 90 megabytes. 03:11.950 --> 03:13.380 Memories are variable. 03:14.520 --> 03:21.760 In this way you can understand exactly what's going on and improve and switch and how many people I 03:21.870 --> 03:22.750 find a. 03:22.960 --> 03:27.350 Then it uses the information about the dummy file systems. 03:27.430 --> 03:33.030 Ok the same information but including the dummy file system and their users. 03:33.220 --> 03:38.720 And if you want to understand this woman it will form just image. 03:39.230 --> 03:39.700 OK. 03:39.790 --> 03:43.110 And then it gives the information in this format. 03:43.210 --> 03:49.700 Suppose you want to understand or you want to see that this uses of a particular directory. 03:49.860 --> 03:56.980 OK so suppose I want to see the best uses for this and there is the one then you can put a word like 03:57.100 --> 03:57.910 this. 03:58.000 --> 04:02.300 Find chanty and then the device location. 04:02.900 --> 04:09.720 We know it gives us information about that particular directory or the particular device. 04:09.880 --> 04:12.960 OK so in this way we can use the day of. 04:12.960 --> 04:13.500 Come on. 04:13.660 --> 04:14.290 OK. 04:14.680 --> 04:21.430 There are some switches if you want to see the information in Megabytes destroyed them if you want to 04:21.430 --> 04:24.450 see in kilobytes then proceed. 04:24.870 --> 04:25.570 OK. 04:26.060 --> 04:32.110 This way this tool uses this information in such detail. 04:32.510 --> 04:37.580 And if you want to see the information based on I know numbers. 04:37.630 --> 04:38.130 OK. 04:38.230 --> 04:46.680 So just floored the switch here hyphen I know this gives the whole information OK according to diner 04:46.700 --> 04:47.290 numbers. 04:47.320 --> 04:49.390 That is the file system. 04:49.390 --> 04:53.110 OK here you can see the columns that this file system. 04:53.110 --> 04:57.230 Then the next column is I notice that is total line and then use it I nodes. 04:57.430 --> 05:04.240 Then out of that the free and then the percentage of that is the percentage and then the Mountain Dew 05:04.300 --> 05:06.050 says or more locations. 05:06.170 --> 05:13.510 OK so in this way understand or we can get this information with this come on. 05:13.870 --> 05:14.560 OK. 05:14.560 --> 05:23.580 So the next command is do you do you use to get information about directly or directly based on information. 05:23.770 --> 05:33.340 OK so suppose if you want to get the information for directly there then just provide the OR suppose 05:33.340 --> 05:37.670 been been directed then just to come on like this do you. 05:37.670 --> 05:45.370 And then and here you can see it gives you the information in this vein what you can't understand what 05:45.370 --> 05:47.710 exactly that number is. 05:47.710 --> 05:52.400 So understand that just proved the option like hyphenates. 05:52.720 --> 05:59.620 And when you pro-white have Canet it gives the amount of space used by that directly been that is 15 05:59.650 --> 06:00.800 megabytes. 06:01.000 --> 06:07.230 If you want to see the grand total users of a directory they're just wild. 06:07.300 --> 06:08.420 SH OK. 06:08.750 --> 06:10.610 OK here I want to see. 06:10.680 --> 06:14.080 Does your four root directory then hit into space. 06:14.080 --> 06:15.630 Permission denied. 06:15.650 --> 06:16.800 All good this. 06:17.010 --> 06:17.370 OK. 06:17.380 --> 06:20.020 It gives us the same information. 06:20.650 --> 06:21.300 OK. 06:21.580 --> 06:26.270 And if you want to see the information about all the files inside the directory. 06:26.500 --> 06:27.000 OK. 06:27.100 --> 06:35.530 Then just prewired the you and me and the directory name like this gives you the information about each 06:35.530 --> 06:41.200 file and each space uses what you can't understand what these numbers are. 06:41.200 --> 06:42.350 So just coordinates. 06:42.400 --> 06:47.380 Now it will use that information whether it is in kilobytes or in megabytes. 06:47.420 --> 06:52.930 OK so in this way you can use these commands to understand the disk space uses this.
