1 00:00:00,390 --> 00:00:01,170 Hello, everyone. 2 00:00:02,100 --> 00:00:09,090 In this listen, I'm going to talk about the hierarchy structure and the Ditrich T.G. and the Linux 3 00:00:09,210 --> 00:00:10,320 operating system. 4 00:00:11,330 --> 00:00:16,910 In any operating system, we have Derek Cheese and Five Systems. 5 00:00:17,890 --> 00:00:25,780 For example, when we had a store, windows are working system, all directors under five systems are 6 00:00:25,780 --> 00:00:27,090 installed under siege like. 7 00:00:28,200 --> 00:00:30,390 Same thing for the Mac operating system. 8 00:00:31,210 --> 00:00:36,480 All directors and five systems are installed on Macintosh hard drive. 9 00:00:37,010 --> 00:00:45,840 However, we can't create directives and five system either on Windows or Mac operating system. 10 00:00:47,540 --> 00:00:54,140 Most Linux distributions have similar directories and five systems. 11 00:00:54,980 --> 00:01:02,050 All those strictures on file systems are installed under the forward slash, as we can see here in the 12 00:01:02,050 --> 00:01:02,480 Seagram. 13 00:01:02,540 --> 00:01:09,680 This is the forward slash and we call this a rule directory or orge fi system. 14 00:01:11,030 --> 00:01:18,680 We consider the root directory or the Route five system the top level or the parent of all the directories 15 00:01:18,710 --> 00:01:20,840 under five systems, a Linux. 16 00:01:21,950 --> 00:01:29,750 We can imagine this hierarchy structure as a family tree and Linux, as we can see. 17 00:01:29,930 --> 00:01:31,850 And Mr. Graham, the top level. 18 00:01:33,270 --> 00:01:39,990 Or the parent of all the directors and the five system, Lennix is the four Senesh, then whatever comes 19 00:01:39,990 --> 00:01:41,550 under the forward slash. 20 00:01:41,790 --> 00:01:43,680 We consider them children. 21 00:01:44,520 --> 00:01:47,790 These children also have our parents. 22 00:01:48,210 --> 00:01:50,660 For other directors and fire system under Tim. 23 00:01:51,800 --> 00:01:54,110 See, for example, we have this slash. 24 00:01:54,140 --> 00:01:58,850 Let's start first with the slash, the forward slash disorder, forward slash. 25 00:01:58,850 --> 00:02:03,440 As we said, it's the root directory or the root five system. 26 00:02:03,830 --> 00:02:11,490 And we consider the forward slash the top level and all Derek choose under fire system and leanness 27 00:02:11,540 --> 00:02:15,110 come under the forward slash. 28 00:02:16,120 --> 00:02:17,630 You also have the slash shoot. 29 00:02:18,130 --> 00:02:19,070 We consider this. 30 00:02:19,300 --> 00:02:24,160 We consider it a special dehorned day victory for the user route. 31 00:02:25,180 --> 00:02:26,890 We have the slash def. 32 00:02:27,950 --> 00:02:34,400 This Takechi has devices Fi's details about the system devices. 33 00:02:35,370 --> 00:02:40,170 For instance, physical devices and other information about devices. 34 00:02:41,300 --> 00:02:50,670 We have also the slash horn we consider to slash home to homogenic to for every user and assistant or 35 00:02:50,840 --> 00:02:55,040 person or Derek Disneyfied unsigned for every user are saved. 36 00:02:56,310 --> 00:03:02,740 And out under the slash world, as we can see here, we have Tom and Mary, the steel users under Tom. 37 00:03:02,810 --> 00:03:06,770 We have a joke to documents and we have also here. 38 00:03:07,570 --> 00:03:09,380 It takes five with context. 39 00:03:09,840 --> 00:03:11,210 The same thing here for Mary. 40 00:03:11,220 --> 00:03:18,100 We have a tale of two pictures and then we have photo, that being Bingy here. 41 00:03:19,770 --> 00:03:26,340 We have the slash temper, as we can see here, and this diagram, this static to you basically is like 42 00:03:26,340 --> 00:03:27,000 a stretch. 43 00:03:27,540 --> 00:03:33,420 However, it stores temporary fires whenever we reboot the system. 44 00:03:34,020 --> 00:03:37,170 Everything is going to be deleted from the slash temp. 45 00:03:37,920 --> 00:03:38,940 We have the slash. 46 00:03:39,100 --> 00:03:43,740 You see this extra A has many dedicated his file. 47 00:03:45,660 --> 00:03:53,310 Shield scripts and programs with their configuration files that execute a Linux distribution, for instance, 48 00:03:54,960 --> 00:04:02,660 bes b best WD Ruber towards security if stab and crosstab tab sign. 49 00:04:04,320 --> 00:04:07,990 Also here we have the slash boot Desertec. 50 00:04:08,050 --> 00:04:16,800 She has boot files and information about conflagration for boot files and details about Kirner of the 51 00:04:16,800 --> 00:04:17,970 Linux disputing. 52 00:04:19,700 --> 00:04:27,790 For instance, some of these searches on fires and under the slash put out a grip and grip, too. 53 00:04:28,270 --> 00:04:30,130 You can see we have to grieve, too. 54 00:04:30,780 --> 00:04:31,730 And we have to grieve. 55 00:04:31,740 --> 00:04:36,890 Also, we have a text file here to grip that safe, which is the confirmation fight. 56 00:04:37,910 --> 00:04:40,310 We also has has he will veto. 57 00:04:40,400 --> 00:04:42,950 As you can see here in this diagram, we have this slash var. 58 00:04:44,600 --> 00:04:50,990 This dad actually has some date information that most of the time changes and updates. 59 00:04:52,040 --> 00:04:54,530 They are common directories and a slash bar. 60 00:04:54,560 --> 00:05:01,010 For instance, log male Spaull and opt for those all those directories. 61 00:05:01,880 --> 00:05:05,370 The most important directory inside the slash bar. 62 00:05:05,420 --> 00:05:06,410 It's the log file. 63 00:05:08,210 --> 00:05:09,230 Just slash bar. 64 00:05:09,230 --> 00:05:11,290 Slash log stores. 65 00:05:11,800 --> 00:05:12,250 This. 66 00:05:12,810 --> 00:05:13,080 OK. 67 00:05:13,160 --> 00:05:20,300 This dedicated a slash look stores unsafe system log files and activities for files systems. 68 00:05:20,300 --> 00:05:21,050 For instance. 69 00:05:21,980 --> 00:05:27,620 Booth that log messages yump that log Mayr log unsign. 70 00:05:29,560 --> 00:05:38,260 We have also here this clash broke, this story contains information about current Lennix Gerner, for 71 00:05:38,260 --> 00:05:49,020 instance, uptime devices, memory information swaps, partitions, C.P.U, an unformed information, 72 00:05:49,240 --> 00:05:49,590 unsoiled. 73 00:05:51,060 --> 00:05:53,470 And there's also other Derek cheese. 74 00:05:53,480 --> 00:06:00,550 And we can notice here in this program, there are as many directors under this under those directives 75 00:06:00,550 --> 00:06:02,470 I just mentioned about some of those. 76 00:06:03,010 --> 00:06:07,000 And we can save directors and files under these directors. 77 00:06:08,430 --> 00:06:09,660 That's conclude our session. 78 00:06:09,960 --> 00:06:10,380 Thank you. 79 00:06:10,510 --> 00:06:12,010 And see you in the next lesson.
