Hi, everyone.

2
00:00:02,670 --> 00:00:07,920
So in this lesson we are going to understand the command, which is c h group.

3
00:00:07,920 --> 00:00:13,710
So C, H group command is used to change the group ownership of any file or directory.

4
00:00:14,580 --> 00:00:22,380
As we know in Linux, we have users and groups that have been given to any specific file or folder with

5
00:00:22,380 --> 00:00:23,400
this directory.

6
00:00:24,810 --> 00:00:26,250
The command is very simple.

7
00:00:26,250 --> 00:00:33,000
You can just simplify C group, the group name that you want to give to any specific file name or the

8
00:00:33,000 --> 00:00:33,990
directory name.

9
00:00:34,920 --> 00:00:43,860
We will also see how you can use C group to recursively give ownership to a new group to any specific

10
00:00:43,860 --> 00:00:45,750
files in a directory.

11
00:00:47,730 --> 00:00:49,260
So it's the practical time.

12
00:00:49,260 --> 00:00:51,060
And let's see the practical.

13
00:00:52,860 --> 00:00:54,610
I'm onto my terminal right now.

14
00:00:54,630 --> 00:00:58,050
I have created a folder called a C Group.

15
00:00:59,330 --> 00:01:00,080
Inside.

16
00:01:00,080 --> 00:01:07,100
You can see there is one directory called s, d, r one and two files called S file one, file two.

17
00:01:08,120 --> 00:01:11,130
So for the file one, you can see the group is root.

18
00:01:11,150 --> 00:01:14,480
I'm changing the group to hack to file for file one.

19
00:01:15,440 --> 00:01:17,390
Let us see the permissions once again.

20
00:01:17,390 --> 00:01:22,610
And you can see the group has successfully changed from root to hack to file.

21
00:01:23,990 --> 00:01:26,810
Let us do the same thing for directory one.

22
00:01:26,810 --> 00:01:31,400
This time I'm changing the group to Curly for directory one.

23
00:01:32,090 --> 00:01:37,310
Let's again see the permissions and we can see successfully for directory one.

24
00:01:37,310 --> 00:01:40,070
The group has been changed to Curly.

25
00:01:41,480 --> 00:01:44,960
Let's go inside the directory and let's see files.

26
00:01:45,410 --> 00:01:46,790
There are two files called this.

27
00:01:46,790 --> 00:01:48,410
File one and file two.

28
00:01:48,980 --> 00:01:56,930
Unfortunately, the group has not been changed for these files, which means whenever we give any change

29
00:01:56,930 --> 00:02:06,920
group command to a new ownership group, it will not recursively change the group for the files.

30
00:02:07,430 --> 00:02:15,020
So for this we are going to use hyphen R, which stands for recursive and let's change group Kali for

31
00:02:15,020 --> 00:02:16,370
all the files.

32
00:02:17,120 --> 00:02:20,270
Let's run the command and see and you can see successfully.

33
00:02:20,270 --> 00:02:27,440
We are able to change the group ownership for all the files inside any directory recursively.

34
00:02:27,890 --> 00:02:28,580
Thank you.
