1 00:00:02,500 --> 00:00:03,770 In the last lectures, 2 00:00:03,770 --> 00:00:07,689 we had a look at command line-based computer interaction. 3 00:00:07,689 --> 00:00:11,260 Now it's time to dive into the actual core content 4 00:00:11,260 --> 00:00:15,100 of this module, and this is learning Git and GitHub, 5 00:00:15,100 --> 00:00:16,900 therefore let's get started 6 00:00:16,900 --> 00:00:20,710 with the Git installation on Mac computers. 7 00:00:20,710 --> 00:00:23,170 Now you can find Git, here, if you will forget, 8 00:00:23,170 --> 00:00:26,040 and then this git-scm.com is the link 9 00:00:26,040 --> 00:00:27,800 we have to use right here. 10 00:00:27,800 --> 00:00:31,270 With this, we are on the Git website. 11 00:00:31,270 --> 00:00:35,260 In here you can find some general information about Git, 12 00:00:35,260 --> 00:00:37,530 but the most important information, here, 13 00:00:37,530 --> 00:00:41,770 is on this, well, screen down here to the right. 14 00:00:41,770 --> 00:00:43,060 There, you can download 15 00:00:43,060 --> 00:00:46,190 the latest source release version of Git. 16 00:00:46,190 --> 00:00:49,080 In my case, this is 2.32. 17 00:00:49,080 --> 00:00:51,890 At the point in time, where you are watching this video, 18 00:00:51,890 --> 00:00:54,733 this might already be a later version. 19 00:00:55,820 --> 00:00:59,483 By clicking onto this Download for Mac button, here, 20 00:01:00,500 --> 00:01:04,170 you are redirected to this page because downloading 21 00:01:04,170 --> 00:01:08,123 and installing Git can be done in different ways. 22 00:01:09,040 --> 00:01:12,580 I'll go with the first one, here, with the Homebrew way. 23 00:01:12,580 --> 00:01:16,620 Homebrew is a package installer for Mac systems, 24 00:01:16,620 --> 00:01:18,800 and it makes installing it very easy. 25 00:01:18,800 --> 00:01:22,360 For this, we first have to look for Homebrew. 26 00:01:22,360 --> 00:01:24,230 Right here, so this is German here, 27 00:01:24,230 --> 00:01:29,230 so this brew.sh is the correct website, let's select this. 28 00:01:30,070 --> 00:01:32,510 And, here, we can now simply install Homebrew, 29 00:01:32,510 --> 00:01:36,653 well, by copying this code, here, into our terminal. 30 00:01:37,880 --> 00:01:40,173 With that, let's bring up a terminal window. 31 00:01:41,280 --> 00:01:42,710 Here it is. 32 00:01:42,710 --> 00:01:46,080 Let's now paste this, well, code, here, 33 00:01:46,080 --> 00:01:47,610 and let's confirm this. 34 00:01:47,610 --> 00:01:50,830 Now we have to enter our computer's password, 35 00:01:50,830 --> 00:01:53,650 and, with that, Homebrew will be installed automatically. 36 00:01:53,650 --> 00:01:57,270 We have to press return to continue here, we'll do that. 37 00:01:57,270 --> 00:01:58,853 So this can take a few moments. 38 00:01:59,960 --> 00:02:01,910 So don't worry if this takes a bit longer, 39 00:02:01,910 --> 00:02:04,060 that's totally normal, we have to download 40 00:02:04,060 --> 00:02:07,010 some things, here, to make this whole package manager work. 41 00:02:08,150 --> 00:02:10,550 And, now, the installation is finally done. 42 00:02:10,550 --> 00:02:12,510 As I said, this can take a few minutes 43 00:02:12,510 --> 00:02:15,520 so don't wonder if you have to wait a bit, 44 00:02:15,520 --> 00:02:17,860 but the cool thing, now, is that with Homebrew 45 00:02:17,860 --> 00:02:21,150 we can now easily install Git. 46 00:02:21,150 --> 00:02:23,100 Let's go back to the Git page, 47 00:02:23,100 --> 00:02:24,643 and let's close this maybe, 48 00:02:25,810 --> 00:02:28,360 and, here, we see the only thing you have to run now 49 00:02:28,360 --> 00:02:30,730 is brew install git. 50 00:02:30,730 --> 00:02:34,480 Guess we can do this, so brew install git. 51 00:02:34,480 --> 00:02:36,650 So we're using this package manager, now, 52 00:02:36,650 --> 00:02:40,570 to install the latest Git version, so let's do this. 53 00:02:40,570 --> 00:02:43,440 This shouldn't take that long, let's see. 54 00:02:43,440 --> 00:02:45,910 With this, the installation is finished 55 00:02:45,910 --> 00:02:49,000 and what we should do now is we should check 56 00:02:49,000 --> 00:02:52,170 whether the installation was successful. 57 00:02:52,170 --> 00:02:56,080 To do this, we can write our first Git command already. 58 00:02:56,080 --> 00:03:00,830 Git commands always start with git, the Git keyword 59 00:03:00,830 --> 00:03:03,690 to, well, tell the computer that we want to interact 60 00:03:03,690 --> 00:03:08,030 with Git, in here, that we want to execute Git commands, 61 00:03:08,030 --> 00:03:11,430 then a space, and then the command that you want to run. 62 00:03:11,430 --> 00:03:15,040 Here, we want to check the installed Git version, 63 00:03:15,040 --> 00:03:18,200 and this can be done by adding two dashes 64 00:03:18,200 --> 00:03:20,903 and then the version keyword here. 65 00:03:22,290 --> 00:03:24,360 With this, by hitting enter, 66 00:03:24,360 --> 00:03:26,930 we should see that the latest Git version 67 00:03:26,930 --> 00:03:29,930 that we installed is 2.32, 68 00:03:29,930 --> 00:03:33,260 so the one that we saw on the website. 69 00:03:33,260 --> 00:03:37,190 In case the installation doesn't show this latest version, 70 00:03:37,190 --> 00:03:41,010 right here, then you can simply close the terminal window, 71 00:03:41,010 --> 00:03:44,650 up here in Terminal and then Quit Terminal, 72 00:03:44,650 --> 00:03:47,140 and then you can start a new terminal. 73 00:03:47,140 --> 00:03:50,280 Because sometimes Homebrew also installs 74 00:03:50,280 --> 00:03:53,500 older versions of Git, well, when installing Homebrew, 75 00:03:53,500 --> 00:03:56,170 and, because of that, the updated version 76 00:03:56,170 --> 00:03:58,330 might not be displayed correctly, here, 77 00:03:58,330 --> 00:03:59,930 in this terminal window. 78 00:03:59,930 --> 00:04:02,600 But, as I said, starting a new terminal 79 00:04:02,600 --> 00:04:07,000 and then running git --version should do the trick here. 80 00:04:07,000 --> 00:04:11,290 With this, we installed Git on our MacOS computer. 81 00:04:11,290 --> 00:04:13,460 If you also want to find out how this works 82 00:04:13,460 --> 00:04:15,790 on Windows machines, feel free to dive 83 00:04:15,790 --> 00:04:17,360 into the next lecture, 84 00:04:17,360 --> 00:04:19,769 otherwise you can skip the next lecture 85 00:04:19,769 --> 00:04:22,483 and continue with the lecture afterwards.
