00:00:04,410 --> 00:00:05,880
I hope you were able to easily

3
00:00:05,880 --> 00:00:07,680
correct this challenge. Let's now

4
00:00:07,680 --> 00:00:09,270
do that together. Let's first

5
00:00:09,270 --> 00:00:12,594
export new variable, 'export MY_NAME',

6
00:00:12,594 --> 00:00:14,280
and the value will

7
00:00:14,280 --> 00:00:16,739
be in my case 'Bogdan'. Now, let's

8
00:00:16,739 --> 00:00:19,920
create a new file called name.sh.

9
00:00:20,310 --> 00:00:24,570
'touch name.sh'. And now let's edit

10
00:00:24,570 --> 00:00:28,110
it using Nano Editor, 'nano name.sh'.

11
00:00:28,410 --> 00:00:30,540
Here on the first line will be '#'

12
00:00:30,540 --> 00:00:32,520
sign, next comes '!',

13
00:00:32,520 --> 00:00:34,650
and afterwards will be path to

14
00:00:34,650 --> 00:00:36,570
corresponding executable that will

15
00:00:36,570 --> 00:00:39,570
launch this executable file '/bin/bash',

16
00:00:40,020 --> 00:00:42,270
and on next line, I'll simply use

17
00:00:42,300 --> 00:00:46,290
'echo $MY_NAME', like this.

18
00:00:46,560 --> 00:00:49,470
Very simple. Let's save this file.

19
00:00:49,920 --> 00:00:51,540
And now let's list files and

20
00:00:51,540 --> 00:00:53,400
folders here in home directory, 'ls

21
00:00:53,400 --> 00:00:55,860
-la'; and I see this newly

22
00:00:55,860 --> 00:00:59,490
created file, name.sh. But now this

23
00:00:59,490 --> 00:01:01,710
file is not executable. You see

24
00:01:01,710 --> 00:01:04,200
here those permissions. I am able

25
00:01:04,200 --> 00:01:06,629
to read, write this file as owner,

26
00:01:06,810 --> 00:01:09,570
and other users in the same group

27
00:01:09,600 --> 00:01:11,580
'bogdan' are also able to read and

28
00:01:11,580 --> 00:01:14,040
write file. All the remaining users

29
00:01:14,100 --> 00:01:16,620
in other groups are able only to

30
00:01:16,620 --> 00:01:18,930
read this file. Now let's add

31
00:01:18,990 --> 00:01:21,150
execution permission for this file.

32
00:01:21,360 --> 00:01:23,880
And I could do that using 'chmod'

33
00:01:23,880 --> 00:01:25,710
command. And here I could use

34
00:01:25,740 --> 00:01:28,830
simply syntax '+x', add execution

35
00:01:28,830 --> 00:01:30,930
permission. And next will come

36
00:01:30,960 --> 00:01:34,050
name of the file, name.sh. Let's

37
00:01:34,050 --> 00:01:36,030
press Enter. Let's verify now

38
00:01:36,030 --> 00:01:38,250
permissions. And now you see that

39
00:01:38,250 --> 00:01:40,590
everyone is able to execute this

40
00:01:40,590 --> 00:01:43,710
file. If you don't want that anyone

41
00:01:43,710 --> 00:01:45,750
else will be able to execute it, you

42
00:01:45,750 --> 00:01:47,910
could of course remove 'x', for all

43
00:01:47,910 --> 00:01:50,010
remaining users and leave 'x' only

44
00:01:50,010 --> 00:01:51,840
for this user. For that you could

45
00:01:51,840 --> 00:01:55,230
use either 'u+x' syntax, first

46
00:01:55,230 --> 00:01:56,940
remove 'x'. Let me show you it

47
00:01:56,940 --> 00:01:58,950
actually quickly. Let's go back and

48
00:01:58,980 --> 00:02:00,900
remove execution permission like

49
00:02:00,900 --> 00:02:04,740
this. And next let's add '+x'

50
00:02:04,770 --> 00:02:07,830
only for user, 'u+x', like so. And now

51
00:02:07,830 --> 00:02:10,020
let's verify permissions. And

52
00:02:10,020 --> 00:02:11,940
you'll see that now only the owner

53
00:02:11,940 --> 00:02:14,550
of this file is able to execute it.

54
00:02:15,120 --> 00:02:17,535
Now let's run it. I could use either

55
00:02:17,535 --> 00:02:19,531
absolute path to this file,

56
00:02:19,531 --> 00:02:22,950
name.sh or relative path. Let's use,

57
00:02:23,100 --> 00:02:25,800
let's say relative path, './',

58
00:02:25,860 --> 00:02:29,580
and name of the file, 'name.sh'; and I

59
00:02:29,580 --> 00:02:31,410
see my name here in the terminal.

60
00:02:31,680 --> 00:02:33,660
That means that this script works

61
00:02:33,660 --> 00:02:36,210
correctly, and this script is able

62
00:02:36,240 --> 00:02:38,070
to get access to environment

63
00:02:38,070 --> 00:02:39,750
variables. Let's quickly have a

64
00:02:39,750 --> 00:02:41,040
look at the contents of this

65
00:02:41,040 --> 00:02:44,100
script. And here's this line that

66
00:02:44,100 --> 00:02:46,800
accesses MY_NAME variable that we

67
00:02:46,800 --> 00:02:48,690
have created before with 'export'

68
00:02:48,690 --> 00:02:51,000
command. Alright, that's all for

69
00:02:51,000 --> 00:02:52,260
solution for this challenge. And

70
00:02:52,260 --> 00:02:53,820
that's all actually for this section.
