1
00:00:00,390 --> 00:00:03,390
OK, now it's time to customize the bash environment.

2
00:00:04,050 --> 00:00:08,130
Now, as we learned previously that unless.

3
00:00:09,190 --> 00:00:11,440
Can do is think fine.

4
00:00:11,590 --> 00:00:15,040
So if I type L L actually L L is not a comment.

5
00:00:15,820 --> 00:00:17,800
It is Elias from the.

6
00:00:18,730 --> 00:00:22,270
And how did I know that by using the alias command?

7
00:00:22,390 --> 00:00:30,370
So alias like this and this NL or type the command, you will notice that and equal unless minus L.

8
00:00:30,520 --> 00:00:31,000
OK.

9
00:00:31,330 --> 00:00:36,960
So that's why l and show us the same result as well as the L.

10
00:00:37,270 --> 00:00:38,560
Now why is this used?

11
00:00:38,800 --> 00:00:45,820
Because sometimes you wrote a long comment and you provide you didn't need to to write it all over again

12
00:00:45,820 --> 00:00:46,630
and over again.

13
00:00:46,630 --> 00:00:54,400
So you want to have, for example, unless nationally and it would show us something like that, then

14
00:00:54,400 --> 00:01:03,280
we can use the Alias Command with the S Command equal, which single quotation I mean the command inside

15
00:01:03,280 --> 00:01:05,740
a single condition and it will be like this.

16
00:01:05,740 --> 00:01:12,610
So if I typed s now, it would show us and s dash and as you can see, but you can see that if I quit

17
00:01:12,610 --> 00:01:18,860
from the tier, I mean, and they open it again, it's clear increase the font size even if I type s

18
00:01:18,880 --> 00:01:19,450
this time.

19
00:01:19,540 --> 00:01:22,150
You can see it will start showing us command not found.

20
00:01:22,300 --> 00:01:23,350
We need to write it.

21
00:01:23,390 --> 00:01:23,920
Yes, again.

22
00:01:24,220 --> 00:01:31,240
Now how to solve such a thing now we already saw that if you remember from the lecture when we put the

23
00:01:31,240 --> 00:01:32,290
environment variable.

24
00:01:32,340 --> 00:01:35,380
Remember the bar one because bar one is not here anymore.

25
00:01:35,620 --> 00:01:45,570
So how to make things better, eminently available by using and modifying that Bashar RC fight?

26
00:01:45,580 --> 00:01:49,570
So actually, we have the card in the next user inside it.

27
00:01:49,990 --> 00:01:58,990
We have the best RC if I scroll up, as you can see that batch R C, this is that no need for the for

28
00:01:58,990 --> 00:02:07,360
the Nunn-Lugar habit or the interactive terminates so that our C and here we can put whatever values

29
00:02:07,360 --> 00:02:07,750
we want.

30
00:02:07,810 --> 00:02:10,370
We learned about the alias, right?

31
00:02:10,389 --> 00:02:13,300
So if I type s, it would show us something like that.

32
00:02:13,690 --> 00:02:19,240
Now, if I want to any aliases, so I will lose an alias command, so the same.

33
00:02:19,720 --> 00:02:25,330
But an alias like this, but I need to remove the sequence.

34
00:02:25,330 --> 00:02:28,760
So an alias s so us now is not found.

35
00:02:28,780 --> 00:02:29,200
OK.

36
00:02:29,560 --> 00:02:30,520
Command not found.
