1 00:00:00,240 --> 00:00:02,750 Hello and welcome back to Adulated. 2 00:00:02,760 --> 00:00:09,270 In this lecture, we are going to see leanness filesystem in the last lecture we have seen how colonics 3 00:00:09,270 --> 00:00:11,100 looks like and how does it work. 4 00:00:11,400 --> 00:00:14,460 But in this lecture, we are going to cover Lennix filesystem. 5 00:00:14,880 --> 00:00:19,980 So the leanness filesystem structure is somewhat different from that of Windows. 6 00:00:20,310 --> 00:00:24,660 Surliness does not have a physical drive like CIDRAP in windows. 7 00:00:25,020 --> 00:00:31,050 So as we all know that the SUDEP is at the base of the filesystem in Windows operating system, but 8 00:00:31,050 --> 00:00:38,850 uses a logical file system instead in case of Linux sort of its top level of our system we are having. 9 00:00:38,940 --> 00:00:41,490 OK, let me first introduce you. 10 00:00:42,480 --> 00:00:44,040 We are having this. 11 00:00:44,250 --> 00:00:45,240 So this is nothing. 12 00:00:45,240 --> 00:00:48,570 But this is the root or file system in Linux, OK? 13 00:00:48,810 --> 00:00:56,580 This is nothing but the fruit or whatever it is, it is the root, OK, it is root. 14 00:00:56,880 --> 00:01:02,520 OK, so now let's see one by one how Linux file system looks like and what does it mean. 15 00:01:02,940 --> 00:01:08,730 OK, so as we all know that this symbol, this is the forward slash symbol, this is the root of the 16 00:01:08,730 --> 00:01:09,510 file system. 17 00:01:09,750 --> 00:01:12,030 It is at the top of all the file. 18 00:01:12,210 --> 00:01:15,850 It is at the top of the file system of Linux. 19 00:01:16,260 --> 00:01:17,960 Now, let's start with the root. 20 00:01:17,970 --> 00:01:23,610 So what is the root is nothing but the home directory of all powerful root user. 21 00:01:24,560 --> 00:01:28,830 OK, now let's see what next week or next is home directory. 22 00:01:28,830 --> 00:01:29,710 So what homework. 23 00:01:29,780 --> 00:01:32,540 So the user's home directory, what does it mean? 24 00:01:32,730 --> 00:01:34,170 So Home Depot is nothing. 25 00:01:34,170 --> 00:01:41,400 But if suppose that if one user is there so it will contain one home and that is why it is called s 26 00:01:41,400 --> 00:01:43,030 user's home directory. 27 00:01:43,740 --> 00:01:46,490 Now let's see next one, which is hyphen media. 28 00:01:46,500 --> 00:01:49,470 So what is or not, if it mediates media, what is this? 29 00:01:49,650 --> 00:01:55,810 So is nothing but where CDs and USB devices are usually attached or mounted to the file system. 30 00:01:56,280 --> 00:02:00,450 OK, now next one, we are having ETECSA. 31 00:02:00,450 --> 00:02:00,930 So what is it? 32 00:02:00,930 --> 00:02:02,370 This what it is. 33 00:02:02,430 --> 00:02:03,300 So it is nothing. 34 00:02:03,300 --> 00:02:07,860 But it is we can say generally contain the leanness configuration files. 35 00:02:08,130 --> 00:02:12,600 So these are the files that control when and how programs start. 36 00:02:13,260 --> 00:02:19,800 So what it is, it is nothing but the leanness file configuration, leanness information files and it 37 00:02:19,800 --> 00:02:22,550 controls when and how program will start up. 38 00:02:23,040 --> 00:02:28,170 So the next that one that we are having it is Leape, which is also Kolas Library. 39 00:02:28,380 --> 00:02:30,720 OK, so what it is so it is nothing. 40 00:02:30,720 --> 00:02:34,790 But this is the place where you will find libraries, what is library. 41 00:02:34,800 --> 00:02:37,840 So as we can take the example of windows. 42 00:02:37,850 --> 00:02:44,750 So this is nothing but the subprogram data similar to the windows be less OK. 43 00:02:44,880 --> 00:02:54,420 So at then we are having been Cauvin is nothing, but we can simply define bin is a place where application 44 00:02:54,570 --> 00:02:56,330 fineries resides. 45 00:02:56,340 --> 00:03:00,270 So what it is, it is a place where application boundaries reside. 46 00:03:00,300 --> 00:03:05,700 So this is equivalent to the executables in Windows operating system. 47 00:03:06,060 --> 00:03:11,400 OK, so we will spend more time with these key directories through our discourse. 48 00:03:11,400 --> 00:03:16,950 So understanding these first level directories is important to navigating through the file system from 49 00:03:16,950 --> 00:03:17,780 the command line. 50 00:03:18,660 --> 00:03:26,850 So it is also important to know before you start that you should not login as a route when performing 51 00:03:26,850 --> 00:03:30,210 routine Taruta industry's basic task. 52 00:03:30,420 --> 00:03:37,200 OK, because anyone who hacks your system so when you are logged in as a route would immediately gain 53 00:03:37,200 --> 00:03:45,730 access to the route account and privileges those your system so long as a regular user when starting 54 00:03:45,730 --> 00:03:51,710 a regular application like the browsing application and running tools like Vizag and so on. 55 00:03:51,900 --> 00:03:55,950 So this is all about the file system of Linux and littleness course. 56 00:03:55,950 --> 00:03:59,700 We are going to see how these files also in the next lecture. 57 00:03:59,700 --> 00:04:05,340 We are going to see, first of all, some basic commands that we use inside Linux operating system.
