00:00:07,110 --> 00:00:09,060
- All right, in order to work with Linux,

2
00:00:09,060 --> 00:00:10,530
you need to log in.

3
00:00:10,530 --> 00:00:14,100
In order to work with Linux,
you need a user account.

4
00:00:14,100 --> 00:00:15,570
Current Linux distributions

5
00:00:15,570 --> 00:00:18,690
create an administrative
user while installing.

6
00:00:18,690 --> 00:00:21,420
On Ubuntu, it's just the
default as you have seen.

7
00:00:21,420 --> 00:00:24,840
On Red Hat and family, there is a choice.

8
00:00:24,840 --> 00:00:26,700
If you create a root user

9
00:00:26,700 --> 00:00:30,180
then you can absolutely create
an additional user account

10
00:00:30,180 --> 00:00:32,340
and grant administrative privileges

11
00:00:32,340 --> 00:00:34,530
and if you do not create a root user

12
00:00:34,530 --> 00:00:39,530
then Red Hat family will also
create an administrative user,

13
00:00:41,010 --> 00:00:44,100
that is a user with pseudo privileges.

14
00:00:44,100 --> 00:00:46,890
We will explore pseudo in the next video.

15
00:00:46,890 --> 00:00:49,590
As an alternative to
this administrative user,

16
00:00:49,590 --> 00:00:50,980
you can use the root user

17
00:00:52,140 --> 00:00:54,226
but you shouldn't be using the root user

18
00:00:54,226 --> 00:00:57,330
because working as root is dangerous

19
00:00:57,330 --> 00:01:00,750
that is because the root user
has unlimited privileges.

20
00:01:00,750 --> 00:01:02,520
It is so easy to do things wrong

21
00:01:02,520 --> 00:01:04,920
if you are using the root account,

22
00:01:04,920 --> 00:01:06,510
that it's a much better idea

23
00:01:06,510 --> 00:01:09,240
to only take these
administrative privileges

24
00:01:09,240 --> 00:01:11,040
if you really need them.

25
00:01:11,040 --> 00:01:12,630
In order to log in,

26
00:01:12,630 --> 00:01:16,770
you can log in from the console,
a graphical user interface

27
00:01:16,770 --> 00:01:20,430
or using SSH to establish
a remote connection.

28
00:01:20,430 --> 00:01:23,490
Now, one big thing in Linux.

29
00:01:23,490 --> 00:01:26,850
Now, if you are using the
Linux graphical user interface,

30
00:01:26,850 --> 00:01:28,470
and if you would only be using

31
00:01:28,470 --> 00:01:30,630
the Linux graphical user interface

32
00:01:30,630 --> 00:01:33,150
then you have limited functionality.

33
00:01:33,150 --> 00:01:35,580
For that reason, many
service don't even run

34
00:01:35,580 --> 00:01:37,470
a graphical user interface

35
00:01:37,470 --> 00:01:39,480
and if you want to work with Linux,

36
00:01:39,480 --> 00:01:43,020
you should learn how to
work with the Linux shell.

37
00:01:43,020 --> 00:01:44,910
However, that doesn't really change

38
00:01:44,910 --> 00:01:47,043
how you are going to log into your system.

39
00:01:47,880 --> 00:01:49,590
The way we have done it

40
00:01:49,590 --> 00:01:53,160
as I've shown you in the
previous lesson is perfect.

41
00:01:53,160 --> 00:01:55,950
You can just install a
graphical user interface

42
00:01:55,950 --> 00:01:58,020
and from the graphical user interface,

43
00:01:58,020 --> 00:02:01,200
you start your terminal, do
all your work in your terminal

44
00:02:01,200 --> 00:02:04,050
and you have full access
to the Linux shell.

45
00:02:04,050 --> 00:02:05,430
The message here is just that

46
00:02:05,430 --> 00:02:07,208
you shouldn't be wasting your time

47
00:02:07,208 --> 00:02:09,600
on learning graphical programs

48
00:02:09,600 --> 00:02:12,300
because these graphical
programs are limited

49
00:02:12,300 --> 00:02:14,700
and they may even not be available

50
00:02:14,700 --> 00:02:17,523
on the Linux machines that
you are going to work with.
