1 00:00:00,000 --> 00:00:01,710 In this lesson we're going to go over 2 00:00:01,710 --> 00:00:03,423 Configuring Account Profiles. 3 00:00:04,680 --> 00:00:06,330 In many cases individual users 4 00:00:06,330 --> 00:00:07,980 will have their own preferences 5 00:00:07,980 --> 00:00:09,660 or unique needs when it comes to 6 00:00:09,660 --> 00:00:11,340 working in a Linux environment. 7 00:00:11,340 --> 00:00:13,560 So we're going to configure a users profile to ensure 8 00:00:13,560 --> 00:00:15,540 that they have customized environments to work in 9 00:00:15,540 --> 00:00:17,280 that fits their requirements. 10 00:00:17,280 --> 00:00:21,720 The first file we're going to investigate is the .bashrc file. 11 00:00:21,720 --> 00:00:24,963 This file is used to customized batch shell environments. 12 00:00:25,860 --> 00:00:29,223 This file is located in the root directory of each user. 13 00:00:30,150 --> 00:00:31,800 So let's check it out real quick, 14 00:00:33,187 --> 00:00:35,373 .bashrc. 15 00:00:36,750 --> 00:00:38,010 Again, this file is used 16 00:00:38,010 --> 00:00:40,083 to customize the shell configurations. 17 00:00:41,040 --> 00:00:43,590 If you look under the user specific aliases 18 00:00:43,590 --> 00:00:45,990 you'll see that their area is blank. 19 00:00:45,990 --> 00:00:49,650 Now, an alias is a way to customize commands. 20 00:00:49,650 --> 00:00:52,380 Now, if every time you wanted to remove a file, 21 00:00:52,380 --> 00:00:54,000 you want to make sure you were prompted 22 00:00:54,000 --> 00:00:56,910 just to make sure that was what you intended to do. 23 00:00:56,910 --> 00:00:59,410 You would input that information there on aliases. 24 00:01:00,360 --> 00:01:03,360 Now, if we take a look at the roots directory 25 00:01:03,360 --> 00:01:06,270 we'll see that under it's bashrc file 26 00:01:06,270 --> 00:01:07,950 that he has the alias set up that way. 27 00:01:07,950 --> 00:01:09,930 because since root is so powerful, you don't 28 00:01:09,930 --> 00:01:13,710 want a scenario where you remove files accidentally. 29 00:01:13,710 --> 00:01:15,260 So let's look at it real quick. 30 00:01:19,290 --> 00:01:22,680 So now, see the aliases are configured here. 31 00:01:22,680 --> 00:01:26,490 So the remove command automatically adds the option, i, 32 00:01:26,490 --> 00:01:28,950 again, which prompts the user to make sure 33 00:01:28,950 --> 00:01:31,110 that that's what they intend to do. 34 00:01:31,110 --> 00:01:33,460 Same thing with the copy, and the move command. 35 00:01:34,590 --> 00:01:36,203 So I'm going to clear this out here. 36 00:01:37,290 --> 00:01:39,000 The next file we're going to investigate is 37 00:01:39,000 --> 00:01:41,073 the bash underscore profile. 38 00:01:42,330 --> 00:01:45,270 This is used to set system wide variables 39 00:01:45,270 --> 00:01:47,550 slightly different from the .rc file 40 00:01:47,550 --> 00:01:50,250 because that's used for bash only. 41 00:01:50,250 --> 00:01:52,470 Now this sets all type of variables. 42 00:01:52,470 --> 00:01:54,263 So let's check this out really quick. 43 00:01:59,820 --> 00:02:02,850 The biggest thing to note here is the path variable. 44 00:02:02,850 --> 00:02:06,420 And this is used to let the environment know where 45 00:02:06,420 --> 00:02:08,820 are we going to store all of our commands. 46 00:02:08,820 --> 00:02:12,750 So Linux needs to know, when we type into command, say, 47 00:02:12,750 --> 00:02:15,870 remove or delete list, anything like that, 48 00:02:15,870 --> 00:02:18,900 it needs to know where these commands are, 49 00:02:18,900 --> 00:02:20,550 so it has a reference to what to do 50 00:02:20,550 --> 00:02:21,900 when those commands pop up. 51 00:02:22,860 --> 00:02:25,110 Now the next directory we're going to go through 52 00:02:25,110 --> 00:02:27,750 is the etc skel. 53 00:02:27,750 --> 00:02:29,400 Every time a user's added 54 00:02:29,400 --> 00:02:31,830 the system automatically copies all the contents 55 00:02:31,830 --> 00:02:34,803 from the etc skel to the user's new home directory. 56 00:02:35,700 --> 00:02:38,280 So whatever files we have in there will be copied. 57 00:02:38,280 --> 00:02:40,253 So we're going to check that out really quick. 58 00:02:46,260 --> 00:02:48,090 So whenever I add a new user, you'll see 59 00:02:48,090 --> 00:02:50,910 that all these files will be added to their home directory. 60 00:02:50,910 --> 00:02:53,793 I'm going to add a file, to the etc porter, 61 00:02:55,003 --> 00:02:56,673 let me have policies2. 62 00:03:03,000 --> 00:03:04,550 Okay, now let's add a new user. 63 00:03:07,738 --> 00:03:09,071 useradd mjordan. 64 00:03:18,360 --> 00:03:23,360 All right, so now let's look at mjordan's home directory 65 00:03:23,430 --> 00:03:24,980 and see if it copied correctly. 66 00:03:32,550 --> 00:03:33,383 There we go. 67 00:03:33,383 --> 00:03:36,813 So now we see policies2, and also policies. 68 00:03:38,670 --> 00:03:41,130 Of course make sure everything else copied. 69 00:03:41,130 --> 00:03:42,640 We'll add the option a 70 00:03:43,830 --> 00:03:45,880 to make sure we see all the hidden files. 71 00:03:47,160 --> 00:03:47,993 And there we go. 72 00:03:49,470 --> 00:03:50,490 So just for a little practice 73 00:03:50,490 --> 00:03:53,490 we're going to go ahead and just add this user to a department. 74 00:03:55,860 --> 00:04:00,120 I'm going to add to our graphics department. 75 00:04:00,120 --> 00:04:02,793 Remember add group, what that stands for. 76 00:04:11,010 --> 00:04:13,380 Now we're just going to look at our group file. 77 00:04:15,090 --> 00:04:16,743 Make sure he in there. 78 00:04:18,000 --> 00:04:19,019 Okay, we can see at the bottom 79 00:04:19,019 --> 00:04:21,510 on the graphics department, mjordan is there. 80 00:04:21,510 --> 00:04:22,503 Still practice, 81 00:04:26,010 --> 00:04:27,210 while we're at it we're go ahead and 82 00:04:29,100 --> 00:04:30,513 put some information about, 83 00:04:39,600 --> 00:04:43,260 okay, again we go to the etc/password 84 00:04:43,260 --> 00:04:44,643 see all new users. 85 00:04:48,000 --> 00:04:49,950 That was created successfully. 86 00:04:49,950 --> 00:04:50,940 One more thing while we're at it 87 00:04:50,940 --> 00:04:52,690 we'll go ahead and set the password 88 00:04:53,700 --> 00:04:54,783 for Mr Jordan here. 89 00:05:01,470 --> 00:05:03,240 All right, had to make sure we had a long password, 90 00:05:03,240 --> 00:05:04,540 so it wouldn't fuss at us. 91 00:05:06,330 --> 00:05:07,860 That wraps things up. 92 00:05:07,860 --> 00:05:10,860 This was a quick example of how to configure user accounts 93 00:05:10,860 --> 00:05:15,420 and understanding the .bashrc batchprofile files. 94 00:05:15,420 --> 00:05:17,850 Again, these are used to create system 95 00:05:17,850 --> 00:05:20,130 and environment wide variables for users 96 00:05:20,130 --> 00:05:21,780 whenever they log into the system. 97 00:05:21,780 --> 00:05:23,580 And I'll see you in the next lesson.
