WEBVTT 00:08.520 --> 00:10.870 Heidi welcome back in. 00:10.880 --> 00:14.930 Listen we're going to learn about the directory structure in Linux. 00:14.930 --> 00:16.690 So what is directory structure. 00:16.810 --> 00:23.570 When we install the Linux operating system then all the important files and folder present inside the 00:23.570 --> 00:27.610 Linux operating system are organized in the brief form. 00:28.340 --> 00:31.310 In a particular directory that is the root directory. 00:31.340 --> 00:36.510 So such organizations have important files and folders in this regard. 00:36.680 --> 00:39.340 Is Called it as the directory structure. 00:39.620 --> 00:41.980 So let's see this structure. 00:42.080 --> 00:48.260 OK practically here and the importance of is directly present inside the room directly. 00:48.260 --> 00:49.050 OK. 00:49.200 --> 00:55.910 Dr. Drew directory's also called the mounting point Taguig and it is represented by a forward slash. 00:55.910 --> 01:03.050 So let's get inside the root directory and unless that is the listing of files and folders. 01:03.140 --> 01:08.320 So here you can see these are the files and folders Brizard inside this group directory. 01:08.330 --> 01:11.620 So let's see the importance of each folder present here. 01:11.650 --> 01:12.190 OK. 01:12.200 --> 01:19.820 One by one who can talk about and they've been directly the BEEN directories used to store the binary 01:19.820 --> 01:21.410 executable files. 01:21.420 --> 01:29.480 Ok so what are binary files that come once the basic commands that we are executing from our previous 01:29.480 --> 01:30.190 lessons. 01:30.230 --> 01:38.490 That is KTAR CD for changing directory or ls or any basic come on the PC Come on. 01:38.600 --> 01:42.170 Are those commands which can be performed by any user. 01:42.170 --> 01:46.500 You don't have to be a super user or administrator to kill DOS. 01:46.500 --> 01:46.960 Come on. 01:46.970 --> 01:54.340 So those concerns are related to that come ons are stored inside the directory. 01:54.470 --> 01:58.090 So let's get inside the brain. 01:58.210 --> 02:07.880 Alice And here again see these are the binary files relating to the basic K-Mart's get. 02:08.440 --> 02:13.430 Now the next directory is directly let's get inside there. 02:13.650 --> 02:20.810 LS Now here you can see the data directory contains the files and folder related to hardware. 02:20.850 --> 02:21.190 OK. 02:21.250 --> 02:22.970 So all the hardware. 02:23.050 --> 02:29.670 Ok the hardware connected to your system that is your monitor motherboard ram OK all the hardware related 02:29.680 --> 02:34.700 information or the files are present inside the girl directly. 02:34.780 --> 02:38.430 So let's get inside the next directory. 02:38.710 --> 02:39.820 The home directory. 02:39.880 --> 02:46.150 The next day at his home directory the home directory is used to store the formation about the user's 02:46.450 --> 02:48.720 present in your next system. 02:48.970 --> 02:55.800 Or you can also see it could get the user profiles or information about the user profiles so that is 02:55.810 --> 02:57.060 fine home. 02:57.210 --> 03:01.460 LS And here you can see it shows the current user active pression. 03:01.480 --> 03:02.720 OK we have cleared it. 03:02.740 --> 03:05.530 Only one user insert the system. 03:05.530 --> 03:09.870 That's why it shows the information about this one user. 03:13.170 --> 03:21.390 The next with IB It is the library the library directory contains all the files related to the library 03:21.450 --> 03:28.080 or you can also call it as it contains the library files which are essential for an operating system. 03:28.080 --> 03:34.890 Or you can also click as the support you find for an operating system or software runestone or the binary 03:34.890 --> 03:37.870 executables that are produced inside indirectly. 03:37.950 --> 03:42.900 So they'll be directory contains the supported files or support files. 03:42.980 --> 03:43.370 OK. 03:43.410 --> 03:45.480 So let's get in line. 03:45.540 --> 03:48.700 I'd be less here. 03:48.740 --> 03:53.050 See these library files present inside this directory. 03:53.100 --> 03:55.240 The next directories media directory. 03:55.360 --> 04:02.970 OK this is used to store the information or the files related to the removable media that is CD-ROM 04:03.490 --> 04:04.770 or pain right. 04:04.800 --> 04:05.450 OK. 04:05.480 --> 04:12.960 Hold on removable media related information or the files gets wholistically. 04:13.380 --> 04:14.130 This. 04:14.250 --> 04:16.830 Here you can see Shulz CD-ROM there. 04:16.840 --> 04:24.380 It shows that currently the CD-ROM is connected to a system and the CD-ROM is removable media removable 04:24.390 --> 04:25.130 CD-ROM. 04:25.290 --> 04:25.650 OK. 04:25.680 --> 04:28.450 Let's get inside the next day. 04:28.530 --> 04:31.860 That is R P D C D D. 04:31.950 --> 04:37.500 This directory's used to store the information or the files related to the add on. 04:37.500 --> 04:40.820 So get the extra add ons that Winstrol. 04:40.910 --> 04:46.010 OK here you go see we install in our previous list in the virtual box guest Eddison. 04:46.020 --> 04:47.310 So that's fine. 04:47.370 --> 04:51.370 Really good to deck this Kurdish unit installed in this directory. 04:51.390 --> 04:53.130 What there were additional software. 04:53.140 --> 04:59.650 Or you can also call it as adults and of soft Durlacher to back down are installed in this directory 04:59.940 --> 05:02.250 the next directory is directory. 05:02.280 --> 05:08.580 So don't confuse the root directory tree present thereby forward slash and destroy directory. 05:08.680 --> 05:14.360 This will directly present here is the home directory for the root user get the root user. 05:14.450 --> 05:19.400 So you can also click as admins user it is the home directory for that root user. 05:19.410 --> 05:25.920 And currently we can get inside this rubric because you need admin circular privilege so you can get 05:25.920 --> 05:27.240 inserted with sudo. 05:27.260 --> 05:30.480 But I don't want to get inside that right now. 05:30.540 --> 05:34.510 So let's talk about the next directory that is it's been. 05:34.560 --> 05:37.860 This directory contains the binary exit cables. 05:37.980 --> 05:38.410 OK. 05:38.460 --> 05:45.630 It also contains the binary executable like bin but the binary code was present in it's been on for 05:45.690 --> 05:53.400 administrator or user or superuser Dukie the files and folders present in this directory are related 05:53.400 --> 05:56.810 to the super user or administrative level user. 05:56.850 --> 06:07.700 So let's take a v v and analysts who get here can see it contains the binary executable really could 06:07.700 --> 06:12.660 be the superuser or administrated it will use it the next day. 06:12.810 --> 06:15.690 R V SRB stands for services. 06:15.690 --> 06:21.420 So this directory contains the information about the services which are relating to the server. 06:21.540 --> 06:24.910 So let's get inside as are v. 06:25.080 --> 06:29.610 LS Ok we we do not have any server installed yet. 06:29.610 --> 06:33.520 So you can see here it does not showing any files or folders present. 06:33.560 --> 06:34.880 So in this Rick. 06:35.160 --> 06:37.140 So let's talk about the next directory. 06:37.140 --> 06:44.800 That is the EMP the MP distend directory is used to store or hold the temporary files. 06:44.850 --> 06:45.270 OK. 06:45.270 --> 06:49.120 When we use any application that application requires. 06:49.120 --> 06:51.290 So some are temporary files. 06:51.300 --> 06:51.600 OK. 06:51.630 --> 06:53.800 It needs some temporary files to be created. 06:53.840 --> 06:58.020 So the files are stored inside this same directory. 06:58.060 --> 06:59.920 OK the next evictees VAT. 07:00.020 --> 07:01.740 That's test for variables. 07:01.800 --> 07:05.220 So it contains the wearable information. 07:05.220 --> 07:11.370 The directories used to store the information about the variables so you can see polygons environment 07:11.380 --> 07:12.480 variables. 07:12.510 --> 07:15.690 So let's get inside Val and Ls. 07:15.740 --> 07:23.240 OK here you can see it contains various directories like back UVs gash Ellaby local lock mail. 07:23.340 --> 07:30.530 So here's the information about all environment variables relating to these systems. 07:30.530 --> 07:32.700 That is mail system lock system. 07:32.730 --> 07:36.330 OK so the next victory is Butyric. 07:36.450 --> 07:41.260 OK so let's get inside both directory and Ls. 07:41.280 --> 07:50.520 Now here kesi actually holds the information about the boot files the important files which are required 07:50.610 --> 07:52.020 during boot operation. 07:52.230 --> 07:56.010 The important files are an idea or the doc AMG will get. 07:56.070 --> 08:01.860 It is an initial Rambis file and the next important is the end user. 08:02.010 --> 08:05.470 So the formula user easy kernel fine. 08:05.530 --> 08:07.230 Get you to the kernel file. 08:07.260 --> 08:13.030 I actually argue that I would use an image file or you can also called as Michelle fine. 08:13.050 --> 08:18.340 So let's talk about the next directory next directory's UTC. 08:18.400 --> 08:20.510 So Skip is right. 08:20.670 --> 08:24.690 You see this deck contains all the configuration files. 08:24.900 --> 08:31.920 This data contains the configuration files relating to braking system the software you install or the 08:31.930 --> 08:39.540 user management related configuration files so you can control the behavior of your braking system or 08:39.690 --> 08:46.380 various You can make these changes to various things by making changes to these files so good. 08:46.440 --> 08:53.920 So we will learn about this in our latter sections are in or what upcoming lessons and how to use or 08:53.930 --> 08:56.130 how did those files present here. 08:56.380 --> 08:58.960 Okay the next line is Dayanidhi already not IMT. 08:58.980 --> 09:01.640 So it is the initial round is fine. 09:01.650 --> 09:03.430 So it is not a folder. 09:03.480 --> 09:05.870 OK so let's talk about the next directory. 09:05.990 --> 09:10.530 Last Place phone this directory is used to store the files and folders. 09:10.560 --> 09:13.080 So which files and folders are stored here. 09:13.080 --> 09:18.750 Suppose there is something wrong is happened to a system or a system crashed due to some reason. 09:18.750 --> 09:25.540 So all the files which are record after that are actually medically restored to this folder. 09:25.620 --> 09:31.650 So this folder is used to restore dat files and folders in the next directories or Mendi these directories 09:31.650 --> 09:38.130 called the mounting directory where you can mount the file system if you want to mount Windows file 09:38.130 --> 09:39.800 system or Windows partitions. 09:39.800 --> 09:44.890 Then you can mount inside's directory the next directories the Aral Sea. 09:44.940 --> 09:49.340 So this directory do not consumes any space on your hard disk. 09:49.470 --> 09:55.500 This directory is used to store the information about the processes that are running on your system. 09:55.500 --> 09:59.440 So let's get inside here and see Alice. 09:59.570 --> 10:00.040 OK. 10:00.410 --> 10:03.960 So holds the process ideas inside this directory. 10:03.960 --> 10:07.620 OK these are the processes that are currently running on the system. 10:07.650 --> 10:09.690 The next directory is indirect. 10:09.750 --> 10:14.990 So then you can start the various processes are running on your system. 10:15.060 --> 10:22.290 So you hold the information or stored the data together during that process as a temporary file system 10:22.290 --> 10:23.000 is required. 10:23.070 --> 10:27.720 So these directories used to store the information about that files. 10:27.880 --> 10:34.500 Or you can also click as every file system which is used during the boot process to hold the information 10:34.500 --> 10:44.850 about that processes or the data files for that operations which are running inside from cd ls. 10:45.030 --> 10:49.950 And here you can see it contains the x see episode or ID. 10:50.040 --> 10:55.380 OK these are the process IDs and various files and folders which are required during boot. 10:55.410 --> 10:58.180 So the next directory is directory. 10:58.200 --> 11:00.240 So what is the use of snap directly. 11:00.240 --> 11:00.830 OK. 11:00.910 --> 11:05.730 You see about this concept of snap or even a so called test nappie. 11:05.790 --> 11:06.220 OK. 11:06.240 --> 11:11.620 In our Lego section but for not just Peniston applications relating to snap. 11:11.620 --> 11:11.990 Get. 11:12.120 --> 11:16.110 This is a new concept KBG is introduced by Ubuntu. 11:16.290 --> 11:21.190 So applications related to this concept are installed in this nabû rectory. 11:21.300 --> 11:23.640 OK the next directory is. 11:23.770 --> 11:29.210 Why is the modern Linux distributions introduces this correctly. 11:29.290 --> 11:35.760 OK it is colorize the word you'll find system which stores the information about the devices connected 11:35.760 --> 11:41.120 to system and it allows you to change the information to read it to them. 11:41.130 --> 11:44.470 So let's see what is it is. 11:44.690 --> 11:45.480 LS Ok. 11:45.530 --> 11:50.120 Here you can see shows that there is directly that is blog bus glass. 11:50.150 --> 11:56.580 The demo devices from gate contesting permission for the hardware and you can't change that information 11:56.580 --> 11:57.290 here. 11:57.300 --> 11:59.910 Let's talk about the last directory that is us. 11:59.910 --> 12:04.420 Are these directories used to store the information about where you are. 12:04.430 --> 12:13.410 Secondly as the files about binary executables source files relating to all users which are accessible 12:13.410 --> 12:19.490 to all types of users like in Windows you can see in Windows there is program files folder is preserved. 12:19.530 --> 12:23.690 So like that it is a program file and folder inside Linux. 12:23.700 --> 12:28.370 OK in this manner all the direct is present here in the Linux directory. 12:28.380 --> 12:30.810 Having their own importance and role.
