1
00:00:03,090 --> 00:00:11,580
Well, one of the most fundamental tasks in Linux or any operating system is adding and removing software.

2
00:00:12,150 --> 00:00:18,630
You will often need to install software that didn't come with your distribution or remove unwanted software,

3
00:00:18,630 --> 00:00:22,410
so it doesn't take up her hard drive space.

4
00:00:23,820 --> 00:00:27,330
Some software requires other software to run.

5
00:00:27,740 --> 00:00:34,350
Uh, so and you will sometimes find that you can download everything you need at once in a software

6
00:00:34,350 --> 00:00:41,850
package, which is group of files, typically libraries and other dependencies that you need for a piece

7
00:00:41,850 --> 00:00:44,520
of software to run successfully.

8
00:00:45,210 --> 00:00:48,510
When you install the package, I'll um.

9
00:00:49,560 --> 00:00:52,380
Uh, we don't when you install a package here.

10
00:00:54,670 --> 00:01:04,960
All the files fit within it are installed together here, as you can see here, we have so many hacking

11
00:01:04,960 --> 00:01:08,410
tools in Linux like password attacks, violence so that we will.

12
00:01:08,800 --> 00:01:13,150
You will learn all of our tools in our course here.

13
00:01:13,480 --> 00:01:14,860
So, um.

14
00:01:16,480 --> 00:01:26,020
In this lecture, we examine three key methods for adding new software a package manager, uh, graphical

15
00:01:26,020 --> 00:01:28,930
user, interface based installation managers and kit.

16
00:01:29,710 --> 00:01:34,780
So using API to let's start using epithet to handle software.

17
00:01:36,320 --> 00:01:43,970
In Debian based Linux distributions, which includes no Kali and Ubuntu, the default software manager

18
00:01:43,970 --> 00:01:51,680
is an advanced packaging tool, a team whose primary command is apt.

19
00:01:51,830 --> 00:01:59,720
Get here and in the simplest and most common form, you can use APT, get to download and install new

20
00:01:59,720 --> 00:02:05,420
software packages, but you can also update and upgrade and charter it.

21
00:02:06,260 --> 00:02:10,460
So let's search a package here now.

22
00:02:10,850 --> 00:02:17,000
Before downloading this software package, you can check whether the package you need is available from

23
00:02:17,000 --> 00:02:22,030
your repository or not, which has placed you where your operating system stays.

24
00:02:22,280 --> 00:02:28,910
Stores information The APC tool has a search function that can check whether the packages available,

25
00:02:29,570 --> 00:02:32,780
so the syntax is informative to NPR team.

26
00:02:33,500 --> 00:02:34,670
Check here.

27
00:02:34,670 --> 00:02:38,660
Search Keyword here.

28
00:02:38,750 --> 00:02:42,410
For example, a key tool and, for example, search Chrome.

29
00:02:43,660 --> 00:02:47,860
As you can see here, we have so many from here.

30
00:02:49,490 --> 00:02:52,870
Cro-Magnon, Sheryl Crow, Muma and others.

31
00:02:55,230 --> 00:02:56,520
Or we can search.

32
00:02:57,200 --> 00:02:58,320
Senator.

33
00:03:02,920 --> 00:03:03,970
Let's see here.

34
00:03:04,420 --> 00:03:12,190
So now I want your adding software to it now that, you know the snort package here.

35
00:03:13,060 --> 00:03:13,690
Um.

36
00:03:18,470 --> 00:03:28,070
As you can see here, exist in your story, so you can use APT, get to download the software to install

37
00:03:28,070 --> 00:03:34,400
a piece of software from your operating systems default repository in the terminal, use the APT get

38
00:03:34,400 --> 00:03:41,870
command, followed by the key word installed here install and then the name of the package you want

39
00:03:41,870 --> 00:03:42,860
to install.

40
00:03:43,760 --> 00:03:51,470
The syntax will look like that, for example, the name of the package here, so let's install small

41
00:03:51,470 --> 00:03:53,630
theater arts.

42
00:03:54,920 --> 00:04:03,970
So if you get error like that odd pseudo promotion, so run this command, which should have permissioned

43
00:04:04,230 --> 00:04:07,820
and interior kelly passport here and as you can see here.

44
00:04:08,240 --> 00:04:13,570
And after all these, uh, operation ten point five megabyte of additional disk space will be yours.

45
00:04:13,580 --> 00:04:17,570
Do you want to continue for this year and enter?

46
00:04:17,630 --> 00:04:19,180
Yes and no.

47
00:04:19,220 --> 00:04:21,350
Now Francis is demanding.

48
00:04:24,130 --> 00:04:24,490
Yes.

49
00:04:40,460 --> 00:04:44,150
As you can see, his snot is installed now.

50
00:04:50,690 --> 00:04:54,890
As you can see, eBay started snored as well.

51
00:04:58,750 --> 00:04:59,980
But I will quit now.

52
00:05:02,120 --> 00:05:02,660
Actually.

53
00:05:05,990 --> 00:05:06,380
So.

54
00:05:07,990 --> 00:05:13,210
We can't remove packages, so you will remember in pictures in Linux, no.

55
00:05:13,660 --> 00:05:22,750
So when removing a software news API to get with the removal option followed by the name of the software

56
00:05:22,750 --> 00:05:23,320
to remove.

57
00:05:23,330 --> 00:05:31,840
So if I want to remove snored here small remove snore care.

58
00:05:32,860 --> 00:05:37,930
Uh, if you get this error, uh, just uh, the pseudo here.

59
00:05:39,840 --> 00:05:41,310
And your county?

60
00:05:42,480 --> 00:05:45,240
A password and a Kindle, yes.

61
00:05:45,570 --> 00:05:45,870
Yes.

62
00:05:58,030 --> 00:06:04,450
So we removed our snort with three more comment here, but again, you will see the task being done

63
00:06:04,450 --> 00:06:08,590
in real time and you will be asked whether you want to continue or not.

64
00:06:09,070 --> 00:06:20,050
So you can enter year two one install and end to, um, keep snorts of signs we will be using again.

65
00:06:21,430 --> 00:06:29,740
So, no, but I removed it, so I will instantly snort again and putting it in remove, snort I to get

66
00:06:29,980 --> 00:06:32,230
install, snort here we will.

67
00:06:32,410 --> 00:06:41,250
I have another, uh, software removing a comment here and you will see it.

68
00:06:41,260 --> 00:06:41,890
And now?
