1 00:00:00,510 --> 00:00:01,170 Hello, everyone. 2 00:00:01,620 --> 00:00:06,720 And this day more I'm going to talk about humans and how to change the default to mask an. 3 00:00:07,680 --> 00:00:11,570 You may ask, is the default permission values for fires and directors? 4 00:00:12,060 --> 00:00:13,780 It's four digits. 5 00:00:13,950 --> 00:00:19,290 Number, for example, the UMass for user student. 6 00:00:20,190 --> 00:00:22,370 It's zero zero zero two. 7 00:00:22,500 --> 00:00:27,690 So this is the default UMass for any or any user in our system. 8 00:00:28,110 --> 00:00:35,430 If I would like to show that you mask in a symbolic sign we just typed option dash uppercase s. 9 00:00:35,720 --> 00:00:37,830 Let's log in as a route user. 10 00:00:39,920 --> 00:00:43,600 And I'll have to check your mask over there. 11 00:00:44,110 --> 00:00:50,200 You can see here your mask is totally different than the you mask for the ordinary user stood so that 12 00:00:50,200 --> 00:00:54,610 you mask what the root is, zero zero two to back. 13 00:00:55,080 --> 00:01:02,860 He said, you know, we're going to do Cat five. 14 00:01:03,640 --> 00:01:04,050 Perfect. 15 00:01:04,180 --> 00:01:04,709 You can see here. 16 00:01:04,930 --> 00:01:12,450 This is the two equations, how to calculate the the default values for either the directory and files 17 00:01:12,450 --> 00:01:14,350 when you're going to create two detectors are fired. 18 00:01:14,770 --> 00:01:19,870 So here's the mask for using student zero zero zero two. 19 00:01:20,380 --> 00:01:27,910 So the default file for directory is seven seven seven and the default value for the fight is six six 20 00:01:27,910 --> 00:01:28,150 six. 21 00:01:28,180 --> 00:01:29,950 So the first one is for the user. 22 00:01:30,010 --> 00:01:31,390 The second one is for the group. 23 00:01:31,780 --> 00:01:33,460 On the third one for other. 24 00:01:33,820 --> 00:01:34,600 Same thing here. 25 00:01:34,750 --> 00:01:35,320 User. 26 00:01:36,310 --> 00:01:36,890 Good. 27 00:01:38,240 --> 00:01:40,200 Sorry group than other. 28 00:01:40,910 --> 00:01:44,360 And the mask is the default your mask for the system. 29 00:01:45,640 --> 00:01:49,190 OK, let's supply some examples to understand this concept. 30 00:01:49,250 --> 00:01:53,180 I'm going to create a text file. 31 00:01:54,560 --> 00:01:54,710 OK. 32 00:01:54,860 --> 00:01:55,550 It takes one. 33 00:01:55,560 --> 00:01:56,090 I'm going to call. 34 00:01:56,090 --> 00:01:56,720 It takes one. 35 00:01:57,170 --> 00:01:57,560 Perfect. 36 00:01:58,100 --> 00:02:02,320 Now I'm going to do EDI dashingly. 37 00:02:02,780 --> 00:02:05,870 Then the text one. 38 00:02:07,490 --> 00:02:17,100 As you can see here, since this is a fire, so would be the default is six, six six and the default 39 00:02:17,100 --> 00:02:18,990 value here is two to two. 40 00:02:19,320 --> 00:02:24,750 So six six six minus two two zero two zero two. 41 00:02:25,200 --> 00:02:31,280 So the value would be six six four. 42 00:02:32,790 --> 00:02:33,990 Let's make a directory 43 00:02:37,220 --> 00:02:38,820 called this one. 44 00:02:38,850 --> 00:02:39,300 Perfect. 45 00:02:39,720 --> 00:02:41,010 List dash oldy. 46 00:02:42,480 --> 00:02:43,090 Perfect. 47 00:02:43,650 --> 00:02:49,470 So the default value for the directory is seven seven seven minus zero zero two. 48 00:02:49,920 --> 00:02:54,660 So the outcome will be seven seven. 49 00:02:57,430 --> 00:02:57,990 Five. 50 00:02:59,020 --> 00:03:08,320 So this is what the user group and other Sam think, if I'm going to log in as I wrote, he was there. 51 00:03:08,320 --> 00:03:12,600 He wrote User first. 52 00:03:12,760 --> 00:03:16,830 I'm going to create first X file or save file. 53 00:03:17,110 --> 00:03:22,410 I'm going to call this one takes to the extreme dash in the. 54 00:03:22,570 --> 00:03:23,810 So t two. 55 00:03:25,390 --> 00:03:29,350 So the different fighting for the takes is six, six, six. 56 00:03:29,470 --> 00:03:35,110 And you ask for the root user is zero zero to two or so. 57 00:03:35,110 --> 00:03:36,570 We'll take just this three digits. 58 00:03:36,660 --> 00:03:37,930 So zero to two. 59 00:03:38,770 --> 00:03:43,990 So this is six five six six six minus zero two two. 60 00:03:44,230 --> 00:03:47,170 So the outcome would be six. 61 00:03:48,630 --> 00:03:49,160 Four. 62 00:03:49,980 --> 00:03:50,440 Four. 63 00:03:51,850 --> 00:03:54,300 If you want to do it, we're going to create a directory. 64 00:03:54,510 --> 00:03:55,740 We'll be the same thing. 65 00:03:56,550 --> 00:03:57,190 We did it. 66 00:03:58,950 --> 00:03:59,550 Perfect. 67 00:04:00,870 --> 00:04:05,590 Oh d the residential deed came along. 68 00:04:06,180 --> 00:04:06,600 Perfect. 69 00:04:06,660 --> 00:04:12,890 So the default photo would be seven seconds, seven minus zero to two. 70 00:04:12,930 --> 00:04:19,649 So the outcome will be seven five five has cleared the screen. 71 00:04:19,709 --> 00:04:26,090 I'm going back to the to the student user. 72 00:04:27,210 --> 00:04:31,710 Card five and then have the equations here. 73 00:04:32,220 --> 00:04:38,370 I'm going to change the you masking the default to match two zero zero two six. 74 00:04:38,610 --> 00:04:39,060 Perfect. 75 00:04:39,840 --> 00:04:43,980 Now I'm going to create a text file. 76 00:04:44,250 --> 00:04:48,810 Let's first create make a directory. 77 00:04:48,960 --> 00:04:52,140 I'm going to make a Jaric to start with a directory of seven, six and seven. 78 00:04:52,860 --> 00:04:56,210 We already double check here. 79 00:04:56,310 --> 00:04:56,630 Yep. 80 00:04:57,000 --> 00:04:58,440 We have a zero zero two six. 81 00:04:58,860 --> 00:05:04,220 I'm going to create a directory right now, so I'm going to call this one for referent. 82 00:05:04,730 --> 00:05:07,720 That s Nash and D deal four. 83 00:05:09,660 --> 00:05:10,300 As you can see here. 84 00:05:10,330 --> 00:05:16,440 Seven seconds second minus two zero two six. 85 00:05:16,710 --> 00:05:22,670 The outcome will be seven five one. 86 00:05:23,650 --> 00:05:24,130 Perfect. 87 00:05:25,120 --> 00:05:26,520 So this is for the user. 88 00:05:28,150 --> 00:05:32,400 And this is the group and this is what the other. 89 00:05:33,540 --> 00:05:35,430 Now let's create a text file. 90 00:05:37,750 --> 00:05:47,060 I'm going to call this one takes five unless nush d f five, 2016. 91 00:05:48,450 --> 00:05:48,930 Perfect. 92 00:05:49,560 --> 00:05:52,230 So we just created text file. 93 00:05:52,890 --> 00:05:57,300 So the default rate for the five is six six six minus. 94 00:05:58,800 --> 00:06:00,310 What is the different value here? 95 00:06:01,510 --> 00:06:05,340 As zero two six zero two six. 96 00:06:05,790 --> 00:06:08,970 So the outcome will be six. 97 00:06:11,570 --> 00:06:12,220 For. 98 00:06:15,120 --> 00:06:16,020 And Xu. 99 00:06:18,690 --> 00:06:23,370 And this is how we calculate the default to mask. 100 00:06:23,950 --> 00:06:26,220 There's a really important point I have to mention. 101 00:06:26,220 --> 00:06:34,980 Once we get a log in or report the system, the system will restart and set the default value again 102 00:06:35,010 --> 00:06:36,600 to the to the default. 103 00:06:37,260 --> 00:06:42,570 You mask value for Dordogne user two zero zero zero two. 104 00:06:43,470 --> 00:06:44,250 And the same thing. 105 00:06:44,310 --> 00:06:47,200 If we change the default, you mask for the root. 106 00:06:47,530 --> 00:06:56,750 Well, the system will reset and an assigned default to mask value to zero zero to two. 107 00:06:57,840 --> 00:06:59,400 That's set for this demo. 108 00:06:59,580 --> 00:07:00,230 Thank you. 109 00:07:00,240 --> 00:07:01,560 I'll see you on the next list.
