1 00:00:00,300 --> 00:00:04,050 So in this video, we'll be talking about the five permissions. 2 00:00:05,330 --> 00:00:13,490 First, let me describe the contents of my territory, and unless, Minister, this is an option, that 3 00:00:13,490 --> 00:00:17,270 is to display the language of the first. 4 00:00:19,250 --> 00:00:21,790 So let's it carefully. 5 00:00:21,830 --> 00:00:29,750 Let's look at this output carefully so we have got the two rows and the first one is the expert and 6 00:00:29,750 --> 00:00:33,170 the psychoanalyst or put that in our directory. 7 00:00:34,220 --> 00:00:37,870 So the let's take a look at this first one. 8 00:00:38,330 --> 00:00:40,700 The first bit indicates that. 9 00:00:42,120 --> 00:00:48,770 Minus, that means there is no special kind of value. 10 00:00:49,050 --> 00:00:51,220 So it just defines that minus. 11 00:00:51,240 --> 00:00:56,730 It means that this fight is justified not only for there are not any shortcuts. 12 00:00:57,570 --> 00:01:03,960 So the next one next to three belongs to the permissions, which is our W X. 13 00:01:04,230 --> 00:01:05,820 There is no it's good. 14 00:01:06,240 --> 00:01:09,790 It's capable, executable permission on this text file. 15 00:01:10,650 --> 00:01:17,160 So generally you will have three permissions on the file, whether you can read or write to the file 16 00:01:17,460 --> 00:01:18,380 or A.. 17 00:01:19,350 --> 00:01:20,070 So. 18 00:01:21,240 --> 00:01:31,620 I had to read write permissions on this product, so this first three bits continues to my user and 19 00:01:31,620 --> 00:01:35,380 the second three which controls to my group. 20 00:01:35,760 --> 00:01:46,140 So in the next, there are users and each user belongs to a group and they will be a road user and that 21 00:01:46,140 --> 00:01:48,050 route user will belong to the road group. 22 00:01:48,600 --> 00:01:53,010 And you can see the user name and this is the group name. 23 00:01:53,190 --> 00:01:55,040 So my name is Nikki. 24 00:01:55,050 --> 00:01:58,340 I have logged in and my group name is Nikki. 25 00:01:58,530 --> 00:02:01,970 So the user name and the group name Moxham. 26 00:02:02,640 --> 00:02:08,150 And these three permissions goes to every other user in the same group of Nikkie. 27 00:02:08,400 --> 00:02:18,300 So there is a user in that group and he will have this read-only permissions and this third parties 28 00:02:18,300 --> 00:02:20,930 are minus minus which stands for read. 29 00:02:20,950 --> 00:02:24,300 And there is no right there is no particular permissions. 30 00:02:25,470 --> 00:02:29,450 And these three bits are for everyone else other than this. 31 00:02:29,460 --> 00:02:30,380 Nikki and Nikki. 32 00:02:31,500 --> 00:02:31,810 Right. 33 00:02:31,830 --> 00:02:32,930 I hope you have understood. 34 00:02:32,950 --> 00:02:33,980 Let me explain it. 35 00:02:34,410 --> 00:02:41,940 So the first tweet indicates whether it is for the auto shop or shortcut order for if this indicates 36 00:02:41,940 --> 00:02:45,210 minus, that means there is no special value. 37 00:02:45,870 --> 00:02:51,300 That means it is normal file and the first three bits goes to the user permissions. 38 00:02:51,630 --> 00:02:55,470 So I am the user and what permissions read and write. 39 00:02:55,470 --> 00:02:57,940 I have no executable permission on this. 40 00:02:58,200 --> 00:02:59,700 I can not run it as a binary. 41 00:03:00,060 --> 00:03:08,610 And what my group, every user belongs to some group in Linux and I belongs to Nikkie Group and that 42 00:03:08,610 --> 00:03:16,560 group users can already read this file and everyone else, everyone else except me and my group can 43 00:03:16,560 --> 00:03:17,540 only read this file. 44 00:03:17,760 --> 00:03:18,540 I will like that. 45 00:03:19,290 --> 00:03:26,760 So coming to this next column, the key is the user name which created this file and the group belongs 46 00:03:26,760 --> 00:03:28,980 to is Nicky, which is also the same name. 47 00:03:29,370 --> 00:03:34,530 And this one enters as the number of bytes in the text for. 48 00:03:36,120 --> 00:03:44,460 And this is that October, this is the month, and the first one is the date of the month now and this 49 00:03:44,460 --> 00:03:52,920 nine three is the date is the time when I created this TextField and in the same way, let's see for 50 00:03:52,920 --> 00:03:58,560 the output, the text for and the first one indicates, I mean, there is hyphen. 51 00:03:58,680 --> 00:03:59,750 This is just awful. 52 00:04:00,060 --> 00:04:03,600 And this fight also has been created by me. 53 00:04:03,840 --> 00:04:08,160 So that's why I have the right permissions on my group. 54 00:04:08,160 --> 00:04:13,550 Members can only read and everyone else except me and my group can only read. 55 00:04:15,450 --> 00:04:25,110 And here you can see Nikki and Nikki and the content of the text and date and time when it is created. 56 00:04:25,650 --> 00:04:33,900 Now, what I will do is I will create a new folder as so as you can see, the new folder has been created 57 00:04:34,020 --> 00:04:35,410 only for the Palestinians son. 58 00:04:37,680 --> 00:04:45,660 So there is A, B, B indicates that this is not a normal fight, this is a directory. 59 00:04:48,620 --> 00:04:54,710 And that is the size of these territories for Euro 96 and the date and time when we are clear that is 60 00:04:54,710 --> 00:04:56,010 October 1st, 1940. 61 00:04:56,510 --> 00:04:58,010 Now we have been created. 62 00:05:00,310 --> 00:05:08,230 So I think that's all for this basic Philabundance, let me explain again and this territory and the 63 00:05:08,230 --> 00:05:16,030 first three belongs to the user permissions and I am the user and I have these rerate executable on 64 00:05:16,030 --> 00:05:16,660 this forum. 65 00:05:17,470 --> 00:05:24,700 And my group members belongs to the Nikkie how only to read and executive permission so they cannot 66 00:05:24,700 --> 00:05:26,770 write any new file into this. 67 00:05:28,090 --> 00:05:35,130 And also everyone else except me and my group have the same permissions as of my group permissions as 68 00:05:35,380 --> 00:05:45,490 an executable so that every everyone except me can read and execute but cannot write a new content into 69 00:05:45,490 --> 00:05:45,880 the text. 70 00:05:45,880 --> 00:05:54,700 For obviously there'll be another user called and he belongs to the group and that route user how every 71 00:05:54,700 --> 00:05:57,690 permission on this letter underfunds. 72 00:05:59,110 --> 00:06:06,520 So let me address again, I'll address myself and I have this that expert and put that. 73 00:06:07,030 --> 00:06:13,240 So there is one comment to change these promotions that you see much more. 74 00:06:16,090 --> 00:06:20,110 So they see it more tenuous, the permissions are the text file. 75 00:06:20,350 --> 00:06:27,000 So what we want to do is we need to specify some special numbers. 76 00:06:27,520 --> 00:06:29,630 So that is for for. 77 00:06:36,710 --> 00:06:45,140 So we need to do the combination of these numbers, four to one four in the sense read and write for 78 00:06:45,140 --> 00:06:46,480 two and one for a ticket. 79 00:06:46,760 --> 00:06:55,850 So if I want to modify this part of the text file for that user, Nikkie and I want to decide how many 80 00:06:56,450 --> 00:07:02,160 parameters I need to go if I want to give all the permissions I need to set for and if I want to say 81 00:07:02,180 --> 00:07:05,900 rerate, I want to add this four and to use a six. 82 00:07:06,380 --> 00:07:12,760 And if I want to execute also, then I want to add six plus one, which is seven. 83 00:07:13,070 --> 00:07:19,850 So if I want to do all distributions, I need to specify the seven as the argument to do more. 84 00:07:20,360 --> 00:07:23,310 So seven defines the every permission to file. 85 00:07:23,480 --> 00:07:23,810 Right. 86 00:07:24,800 --> 00:07:31,770 So I want to use seven and we need to pass another two numbers in the same way like this. 87 00:07:32,000 --> 00:07:38,450 So this first number is for the user and the second number, six seven seven for that group, and the 88 00:07:38,450 --> 00:07:39,570 third number is for others. 89 00:07:40,310 --> 00:07:42,220 So this is like similar to this one. 90 00:07:42,470 --> 00:07:44,630 You can compare this number to these three. 91 00:07:47,970 --> 00:07:54,780 So these three parts, so the five to seven, part seven indicates this, the user permissions and the 92 00:07:54,780 --> 00:07:59,490 second seven indicates the group permissions and the 37 indicates the right permission. 93 00:07:59,550 --> 00:08:02,040 I mean, accept other permissions. 94 00:08:02,490 --> 00:08:04,670 So I said no. 95 00:08:05,450 --> 00:08:06,990 I said myself, no. 96 00:08:06,990 --> 00:08:10,370 I can see the color has been changed to green. 97 00:08:10,380 --> 00:08:13,620 That means it has been said that it could be. 98 00:08:14,430 --> 00:08:18,700 So I can see the very permission has been given to it. 99 00:08:19,020 --> 00:08:20,030 So I am the user. 100 00:08:20,310 --> 00:08:24,720 I can rewrite that file and then rewrite my group. 101 00:08:24,720 --> 00:08:29,720 Members can also be redacted and others, everyone else can also read it. 102 00:08:30,690 --> 00:08:32,050 So this is the seven seven. 103 00:08:32,050 --> 00:08:33,780 So if I see only. 104 00:08:35,230 --> 00:08:37,780 Seven, six, six. 105 00:08:39,120 --> 00:08:44,400 Now, if I press for a Palestinian answer, no, as you can see. 106 00:08:45,470 --> 00:08:52,580 Digicom will bid for the group members and others has been turned off because we have given only the 107 00:08:52,580 --> 00:08:55,310 six six minute press, right? 108 00:08:55,340 --> 00:08:55,760 Right. 109 00:08:57,020 --> 00:08:59,090 There is not enough. 110 00:08:59,360 --> 00:08:59,900 Six. 111 00:09:01,610 --> 00:09:08,900 So I am the user, I can Google it executable, I decoded and my group members can only read write and 112 00:09:08,900 --> 00:09:13,730 others can only read, write, can articulate what I want to read. 113 00:09:13,760 --> 00:09:14,750 I just say. 114 00:09:16,520 --> 00:09:17,870 Seven for four. 115 00:09:18,050 --> 00:09:25,760 That means I can relate, execute and group, my group members can only read and others also can only 116 00:09:25,760 --> 00:09:26,030 read. 117 00:09:27,870 --> 00:09:37,510 And as you can see, the tactical retreat, we don't know right now that you could read only so I can 118 00:09:37,550 --> 00:09:39,840 read my group members can only read. 119 00:09:39,850 --> 00:09:52,320 And also there's only so if I set fire to creating a new file, Numerati and if I share this mindset. 120 00:09:53,230 --> 00:10:01,150 So the new file contains some permissions before when I created the file so I can relate and everyone 121 00:10:01,150 --> 00:10:02,310 else can only be. 122 00:10:02,800 --> 00:10:10,330 So where are these default permissions have been approved is means there is a korangal. 123 00:10:10,330 --> 00:10:16,810 You might ask for it if I say you must minhas it, it gives us some options. 124 00:10:16,810 --> 00:10:19,750 You need to pass the mod for these options. 125 00:10:20,380 --> 00:10:26,080 So you work seven seven seven seven seven seven from here on. 126 00:10:26,080 --> 00:10:27,910 What if I create any new file? 127 00:10:28,210 --> 00:10:35,710 These permissions will be applied to the new file, so I don't want to mess with these permissions. 128 00:10:35,710 --> 00:10:42,190 So simply I just saying that there is a command you must you you can change the default permissions 129 00:10:42,280 --> 00:10:42,760 of it. 130 00:10:43,030 --> 00:10:44,140 New file folder.
