WEBVTT 00:09.940 --> 00:11.860 Hi will come back. 00:11.860 --> 00:15.270 Welcome to the part two of the Basically next commands. 00:15.310 --> 00:15.790 OK. 00:15.940 --> 00:22.070 In our previous lesson we learn how to create a folder how to move from one folder to another. 00:22.190 --> 00:22.510 OK. 00:22.510 --> 00:26.690 All these are the basic commands that we learn in this lesson. 00:26.680 --> 00:32.660 We're going to learn some of the important and are once the commands inside the linux. 00:32.690 --> 00:36.260 So in this lesson we're going to learn more about the. 00:36.260 --> 00:36.910 Come on. 00:37.100 --> 00:37.610 OK. 00:37.760 --> 00:43.030 And then we're going to learn how to restart and shut down your computer. 00:43.220 --> 00:43.550 OK. 00:43.550 --> 00:44.710 Or your server. 00:44.840 --> 00:48.580 And also we're going to learn how to install the guest additions. 00:48.600 --> 00:48.970 OK. 00:49.070 --> 00:51.700 Inside this Ubuntu Linux server. 00:51.700 --> 00:52.170 OK. 00:52.370 --> 00:54.180 So let's see step by step. 00:54.200 --> 00:55.770 All these commands. 00:56.120 --> 01:02.490 So before actually performing any operation we need to connect them to the Internet. 01:02.620 --> 01:03.080 OK. 01:03.200 --> 01:10.550 So after installing virtual box actually medically configured for the Internet if you're not getting 01:10.580 --> 01:12.690 Internet into the watch box. 01:12.690 --> 01:13.030 OK. 01:13.070 --> 01:20.120 What do you need to do is first select the operating system from this list here and then click on settings 01:20.900 --> 01:23.070 and here click on network. 01:23.410 --> 01:23.930 OK. 01:24.050 --> 01:28.150 And here make sure you have selected the next option. 01:28.180 --> 01:34.740 Ok amongst all these options you should be selected this that option and this option should be checked. 01:34.760 --> 01:46.040 At this point and click OK and after that Google file preferences and here just click on that in this 01:46.120 --> 01:51.720 that network to make sure this option is present here and it should be checked out. 01:51.860 --> 01:58.580 And if you do not get this option here then just click on this button that this will add this option 01:58.640 --> 01:59.700 at this point. 02:00.140 --> 02:06.530 And after that just click on this host to make sure this virtual box has so little that are kept that 02:06.530 --> 02:08.940 option should represent here. 02:09.090 --> 02:11.460 And of the conference this. 02:11.600 --> 02:12.400 OK. 02:12.890 --> 02:15.950 So now let's move on to our virtual server. 02:16.400 --> 02:18.710 So now let's talk about the Suda. 02:18.890 --> 02:25.750 So what is pseudo pseudo stands for super user do or substitute user do sudo is. 02:25.770 --> 02:27.730 C'mon is a powerful tool. 02:27.820 --> 02:28.170 OK. 02:28.190 --> 02:31.840 Which users do administrators level privileges. 02:32.050 --> 02:32.530 OK. 02:32.780 --> 02:39.250 What that means is ok I suppose you are a normal user normal user on the server. 02:39.370 --> 02:45.530 And if you don't do exec you some sort of commands and you are trying to execute that. 02:45.530 --> 02:49.940 So what happens is that one cannot be executed. 02:50.000 --> 02:55.810 It gives you the error that you don't how the admin is to do well fruitage execute the command. 02:55.820 --> 02:59.350 That means you do not have that right exec come on. 02:59.510 --> 03:02.500 But sudo can do that right. 03:02.510 --> 03:06.720 Or the administrators will privilege to execute the come on. 03:06.760 --> 03:14.780 OK so if you are not a super user or root user OK within the next list and about what is the root user. 03:15.020 --> 03:19.160 But for just and then you can exec you at once. 03:19.250 --> 03:19.950 Come on. 03:20.000 --> 03:20.410 OK. 03:20.510 --> 03:28.310 With the help of sudo You can also install software on various packages with the help of pseudo Sulu's 03:28.430 --> 03:31.030 normally don't live in the early 1980s. 03:31.040 --> 03:33.010 Ok bye guys. 03:33.140 --> 03:36.110 As Robert Cox and Cliff Spencer. 03:36.240 --> 03:42.740 OK but the current version that we are using is Dola Pratt maintained by Todd Miller. 03:42.950 --> 03:45.790 So let's get started with sudo. 03:46.040 --> 03:46.630 OK. 03:46.850 --> 03:54.120 First of all of installing overdrew server or a Linux system you need to update all the packages. 03:54.150 --> 03:57.150 OK so who do this. 03:57.270 --> 04:07.600 There is a come on call a pseudo BT hyphen gig space update. 04:07.730 --> 04:08.250 OK. 04:08.480 --> 04:10.880 You need to update the packages list. 04:10.880 --> 04:16.210 This update will update the packages list or get to the newest version. 04:16.350 --> 04:16.890 OK. 04:16.970 --> 04:20.310 So hit enter. 04:20.490 --> 04:24.230 It's updating the packages list OK on our system. 04:26.060 --> 04:26.370 OK. 04:26.390 --> 04:29.640 It takes some time to get the package list. 04:29.640 --> 04:32.280 OK it depends on your network speed. 04:34.110 --> 04:34.550 OK. 04:34.590 --> 04:39.720 Or back at least it's updated here but only updating is not enough. 04:39.720 --> 04:45.810 It does come on only upgrade the list of packet is it not install any package there. 04:45.850 --> 04:47.560 It only abridged the list. 04:47.570 --> 04:57.260 OK install the latest updates you need to type the command sudo get a click click of good will update 04:57.360 --> 05:01.880 the packages in cells that are present on your system. 05:02.010 --> 05:05.440 So just type this come on and hit enter. 05:05.850 --> 05:10.270 OK click like. 05:10.480 --> 05:16.060 It is a very essential operation to perform after installing an open server. 05:16.080 --> 05:16.610 Ok. 05:16.780 --> 05:23.830 Otherwise you will get the error messages when you are trying to install any software or any package 05:23.880 --> 05:25.500 Hoki on your server. 05:25.600 --> 05:28.130 You need to first update and then upgrade 05:32.250 --> 05:36.370 the upgraded in-progress OK. 05:36.380 --> 05:42.090 We going to learn more about this suruh tools as we move forward in our cost. 05:42.150 --> 05:49.920 Get now is extracting the packages so you know finally we are done here. 05:49.960 --> 05:52.250 All the system is upgraded now. 05:52.270 --> 05:57.280 The latest was you know Sophos sordidness time clear. 05:57.280 --> 05:58.450 Clear the screen. 05:58.720 --> 06:03.270 Now we use the sudo command to get and upgrade the system. 06:03.340 --> 06:03.740 OK. 06:03.880 --> 06:11.790 If you are family or witer one one and then you know there is combine all that tree with display the 06:11.800 --> 06:14.030 files and folder entry format. 06:14.040 --> 06:14.640 OK. 06:14.710 --> 06:21.430 In the current view or the current directory so we can also perform the same operation in the links 06:21.430 --> 06:22.460 environment. 06:22.470 --> 06:27.300 But let's see what happens when I type 3. 06:27.530 --> 06:30.030 It says that no such file directly. 06:30.040 --> 06:38.170 That means that recombined is not available here but we can install that command on the system with 06:38.170 --> 06:39.260 the help of sudo. 06:39.370 --> 06:39.810 OK. 06:39.910 --> 06:41.990 So let's see how to install a command. 06:42.130 --> 06:44.420 With the help of sudo. 06:44.800 --> 06:53.510 So save sudo click install Crea it asks for the password. 06:53.890 --> 06:59.300 So now it's installing OK. 06:59.320 --> 07:00.970 Finally it's done. 07:00.990 --> 07:01.750 So you type. 07:01.750 --> 07:03.730 C'mon tree. 07:04.200 --> 07:12.360 OK here you can see on our current directory there is a folder the one that was created in the previous 07:12.360 --> 07:13.440 lesson. 07:13.440 --> 07:20.520 So schools move in to the root directory and type the command tree. 07:20.880 --> 07:25.660 OK now you can see it's showing all the files and folders in tree format. 07:25.680 --> 07:28.860 OK which are present in the root directly. 07:29.270 --> 07:34.630 OK to good this operation you can press control see. 07:34.950 --> 07:36.510 Let me show you again. 07:36.630 --> 07:42.810 Type 3 and I'm going to press conference see the operation is paused here. 07:42.970 --> 07:48.550 So in this way you can install any command which is not already present there. 07:48.650 --> 07:55.470 OK on the Ubuntu server with the help of sudo and then you can perform the operation. 07:55.560 --> 08:00.660 You can cancel any operation at any time by pressing the control c key. 08:00.870 --> 08:02.850 So just clear the screen. 08:03.050 --> 08:05.710 OK let's get to the whole. 08:06.810 --> 08:11.000 The next thing that I would like to show you here is installing guest additions. 08:11.010 --> 08:18.110 So what our guest additions so the operating system that we install here on what tool box is called 08:18.150 --> 08:23.850 has the operating system and the operating system which is actually stored on our computer. 08:23.920 --> 08:26.060 Called as the host operating system. 08:26.130 --> 08:33.930 So as the name suggests just wishes that means it enhances the feature of the operating system. 08:33.960 --> 08:43.960 After installing install the stations first you need to go through devices insert stations logging of 08:44.010 --> 08:45.710 clicking that. 08:45.900 --> 08:55.980 So now just go to CD in media folder and type sudo mount. 08:56.010 --> 08:59.040 Here we are performing the Mohmed operation. 08:59.080 --> 09:10.810 So the CD-ROM stays covered flash media and CD ROM and hit enter. 09:11.850 --> 09:14.750 Now it's inside producted OK it's OK. 09:15.150 --> 09:15.590 No. 09:15.610 --> 09:19.030 Next you can just go in to see the raw 09:21.810 --> 09:27.080 Ogilvie or his CD Rob and hit Alice again. 09:27.410 --> 09:37.310 No it will show you various packages here are wiliest files so you just need to type sudo dot forward 09:37.310 --> 09:38.370 slash. 09:38.670 --> 09:48.220 OK and the box Linux Elisha's got run. 09:48.320 --> 09:51.180 You need to read this fine. 09:51.350 --> 09:52.590 OK here. 09:52.650 --> 09:56.780 Forward slash should be present the current directory and hit enter. 09:58.610 --> 10:12.010 No spelling mistake okay now enter nobody's installing the guest additions of the installing guest additions 10:12.040 --> 10:14.240 we can get various features. 10:14.260 --> 10:15.570 OK. 10:19.080 --> 10:19.380 OK. 10:19.430 --> 10:28.010 In this way you can install the guest additions on your system with the help of this pseudo the next 10:28.010 --> 10:35.090 comando that I would like to show you a reboot to boot command is used to reboot your system so reboot 10:35.120 --> 10:38.290 just type reboot and he didn't. 10:38.570 --> 10:39.060 OK. 10:39.170 --> 10:44.770 And this reboot your system will get Let's see case reboot the 10:52.520 --> 10:54.260 OK we are here. 10:54.330 --> 11:00.690 So type the user name then us. 11:04.460 --> 11:08.720 In this way you can pull for the reboot operation on. 11:08.730 --> 11:12.870 So the next come on that show you shut down. 11:12.980 --> 11:13.260 OK. 11:13.280 --> 11:15.810 It is the final come on in this tutorial. 11:15.980 --> 11:24.050 So then you had shut down it shut down the system but it takes some time to shut down the system. 11:24.120 --> 11:31.420 But if you want to shut down immediately then you just need to Plourde an option now and hit enter. 11:31.640 --> 11:31.980 OK. 11:32.060 --> 11:34.180 Now it's shutting down the system. 11:34.670 --> 11:35.140 OK. 11:35.240 --> 11:40.400 In this way it shut down the system will get in this lesson we'll learn about the pseudo column on how 11:40.400 --> 11:44.740 to update and upgrade the system how install the guest additions. 11:44.780 --> 11:48.310 OK and how to reboot and shut down the system OK. 11:48.470 --> 11:52.570 Susan most powerful tool in the Linux environment. 11:52.580 --> 11:53.100 OK. 11:53.330 --> 11:58.360 OK we will learn more about this too as we move forward in this course. 11:58.370 --> 11:58.910 OK. 11:59.150 --> 12:01.540 But for now our system is shutting down. 12:01.610 --> 12:02.090 OK. 12:02.210 --> 12:05.270 So let's meet in the next territorial.
