These are the user uploaded subtitles that are being translated: 1 00:00:00,840 --> 00:00:06,090 Let's talk a little bit about package management which is really a fancy way to say how we can install 2 00:00:06,090 --> 00:00:09,280 and uninstall software and the S.. 3 00:00:09,300 --> 00:00:14,820 Our objective is to understand and practice how we can install and remove software from our cat Linux 4 00:00:16,400 --> 00:00:23,480 and Linux packages equal software that's anything that you would install or remove. 5 00:00:23,610 --> 00:00:26,860 Obviously you might wish to do that at any point in time. 6 00:00:27,060 --> 00:00:32,560 Matzos for example that we so in are heading for beginners course doesn't exist by default. 7 00:00:33,100 --> 00:00:36,280 You might decide that I like NASM and I want to use that. 8 00:00:36,390 --> 00:00:38,640 So you will have to install it on canon. 9 00:00:39,060 --> 00:00:44,280 The challenge though is that these packages often required that tendencies and these are additional 10 00:00:44,280 --> 00:00:50,400 pieces of software that are required to be installed while all before you install the main software 11 00:00:50,400 --> 00:00:51,790 that you want to use. 12 00:00:52,050 --> 00:00:57,780 So if we're taking the necessary example you might be needing to install additional software before 13 00:00:57,780 --> 00:01:00,390 you actually install Netta's itself. 14 00:01:00,480 --> 00:01:07,590 Luckily how other different Linux distributions have different package management software package management 15 00:01:07,590 --> 00:01:10,090 software will take care of that for you. 16 00:01:10,140 --> 00:01:16,890 It will install the dependencies and you can use it to remove or update packages. 17 00:01:17,070 --> 00:01:22,430 These package management software have different names depending on the Linux flavor that you are using. 18 00:01:22,440 --> 00:01:30,000 For example Redhat has a package management software that's called Yum for Debian which is what's Cairney 19 00:01:30,000 --> 00:01:33,700 based on it's called abt 8. 20 00:01:33,920 --> 00:01:41,510 It stands for advanced packaging too and there are different commands that we can use with AAPT. 21 00:01:41,550 --> 00:01:48,410 For example if I want to find out about a package I can use the ABT dash cache search. 22 00:01:49,020 --> 00:01:54,370 If I want to see information about a package I can do that abt cache show to install. 23 00:01:54,390 --> 00:02:03,480 I can do the bittie get install and remove it will be a pretty They move the moving package with all 24 00:02:03,480 --> 00:02:05,210 its configuration files. 25 00:02:05,220 --> 00:02:12,390 I can do abt get Berge when we normally install the package. 26 00:02:12,390 --> 00:02:18,710 For example let's say S-sh or FTB we might actually change the configuration of this package. 27 00:02:18,720 --> 00:02:24,100 Let's say for example by default as this age operates on point 22. 28 00:02:24,270 --> 00:02:27,810 But I want to change that I want it to be on board 22:22. 29 00:02:27,810 --> 00:02:36,000 For example I can do that by changing the configuration of S-sh if I do a BT get remove it will remove 30 00:02:36,000 --> 00:02:42,600 this sh package but it will leave the configuration files and this is just in case I decide to re-install 31 00:02:42,600 --> 00:02:44,020 it again. 32 00:02:44,070 --> 00:02:48,330 I'll have my configuration files intact so I wouldn't have to reconfigure it all over. 33 00:02:48,660 --> 00:02:53,820 But if I decide I don't want it at all that I don't want the configuration files I can use the purge 34 00:02:53,820 --> 00:02:54,420 command. 35 00:02:54,420 --> 00:03:02,820 The abt get purge Let's see how that looks like practically I'm going to go to the menu on Cadie the 36 00:03:02,820 --> 00:03:09,170 graphical menu and I want to see if I have any sort of FTB client So let's say I want to connect and 37 00:03:09,170 --> 00:03:10,660 have the beast. 38 00:03:11,520 --> 00:03:15,360 So I'll just type FTB in the search box and there are no results. 39 00:03:15,360 --> 00:03:21,450 There isn't anything I can use to graphically connect the piece of. 40 00:03:23,310 --> 00:03:31,870 So let's use the command that we just the first letter was abt cache search to search for a package 41 00:03:32,340 --> 00:03:39,430 and I'm going to type graphical FTB And here's a bunch of results. 42 00:03:39,430 --> 00:03:43,960 The third one file Zilah looks like something I want to try. 43 00:03:43,960 --> 00:03:51,440 It says it's a full featured graphical FTB PSN has a freebie light that sounds perfect. 44 00:03:51,460 --> 00:04:01,420 Let me find out a little bit more information about it and I do that using the ABT cache show and the 45 00:04:01,420 --> 00:04:05,840 name of the package file Zilah. 46 00:04:05,940 --> 00:04:09,410 I'll scroll up to read about it a little bit. 47 00:04:11,080 --> 00:04:14,130 So that's the package name and look at that. 48 00:04:14,140 --> 00:04:17,230 These are the dependencies that we talked about. 49 00:04:17,230 --> 00:04:23,320 For me to be able to install file Zilah without a package management tool I would have had to install 50 00:04:23,410 --> 00:04:26,920 all of these dependencies first myself manually. 51 00:04:27,610 --> 00:04:34,060 Luckily I don't have to do that on a little bit more about it in the description and that looks like 52 00:04:34,060 --> 00:04:35,000 it's perfect. 53 00:04:35,010 --> 00:04:35,650 What I want. 54 00:04:35,650 --> 00:04:41,000 It's a Ford FTB and I can use it to connect graphically to the server. 55 00:04:41,050 --> 00:04:43,310 So I'm just going to go ahead and install it. 56 00:04:43,540 --> 00:04:52,240 I'll type abt get install file Zilah and it asks me if I want to continue or not. 57 00:04:52,240 --> 00:04:54,120 I can type yes if I want to. 58 00:04:54,250 --> 00:04:54,790 I'm going ahead. 59 00:04:54,790 --> 00:05:04,000 No for now just to show you another option I can when they get do the minus y option which automatically 60 00:05:04,000 --> 00:05:04,430 answers. 61 00:05:04,440 --> 00:05:08,200 Yes and here we go. 62 00:05:08,230 --> 00:05:14,380 Take a few seconds to install and once that's done I can go back to my menu 63 00:05:17,890 --> 00:05:20,390 and type TV. 64 00:05:20,860 --> 00:05:24,850 And now I have a new software installed on a new package installed. 65 00:05:24,930 --> 00:05:28,060 I click on that to open it and here we go. 66 00:05:28,060 --> 00:05:35,060 This is a graphical FTB client I can use that to put in the host section. 67 00:05:35,110 --> 00:05:41,610 The name of the FTB server I want to connect to the user name the passwords and the. 68 00:05:41,960 --> 00:05:50,980 I can use that to connect to any FTB server I wish going to close that for now and let's say I decide 69 00:05:50,980 --> 00:05:53,510 that I want to remove Fosler I'm done with it. 70 00:05:53,530 --> 00:05:55,270 I don't want to use it or I don't like it. 71 00:05:55,270 --> 00:05:56,910 I want to try something else. 72 00:05:56,950 --> 00:06:03,900 Whatever it is I just decided I want to remove the math for that AP ticket to remove the package name. 73 00:06:03,900 --> 00:06:08,710 Fosler takes a few seconds to remove 74 00:06:12,470 --> 00:06:13,660 and done. 7926
