Linux - Adding users to group

so till now we have created users and

groups we have modified the users and

groups entries we have seen how we can

set the password age but now I'm going

to show you how we can add a user to a

group as we know the user when it's

created automatically it gets a owner

group now if I want to add some members

into the group how we are going to do

that that's what we are going to see

here very first thing whenever we create

or whenever we create the user and if I

want to add the user into my groups we

can add multiple in users into a same

group or we can add user into multiple

groups as well so to assign the common

permission to multiple users you can add

the user into the same or different

groups the groups can be our owner group

or it can also be a supplementary group

same way the users which we are going to

add into the crib so for that we need to

modify the file called as /dt sea slug

group where it stores all your owners

per group as well as the supplementary

group just we need to move into the file

and modify the entries so how we are

going to modify the entries and how we

are going to add the user into group

into the file / ethics in slash group

that we are going to say into the

terminal so here we are going to see how

we can add the users into a particular

group so already we have seen

deformations we have refined the

permission from the owner or group and

others but we haven't seen it

practically whether it works or not so

here what we are going to do is I'm

logged in through the root and root has

created a directory into the slash

itself I'm going to create a directory

with name demo or root share I can say

okay so let us check for deformation

your root share has so first let us move

into the slash and I'm going to check

for the formation of root shell

so we have multiple files here

let us check correctly other and we have

the route share the default formation is

read read and execute for the owner read

and execute for the crop and returning

secured for the others so I'm just going

to change the formation seven seven zero

for route share so now we can check this

is route share directory has deformation

seven seven zero now

no this is my user 1 this user 1 tries

to move into the /root share so I just

showing you permission denied /root

share so sure again there is no such

file or directory ok that is 2 twice I

have written sure you can see permission

is denied means even though you will be

able to see this rectory if I want to

directly more one mount point I can I'll

be able to see this root directory as I

am not added as a member of this group

that is a routes group I won't be able

to get access to it even I won't be able

to move into this directory

correct neither one that I should be

able to move into this rectory I have to

be a member of the roots crop so how

will will be doing it what we will be

doing is through the route you can move

into the EDC group into the group we are

going to add the username over here

user one so this is the group member of

user that is their super user with now

now cane if this user looks for the

permission he knows that he is in a

group member of your root so now if it

tries to move into the root share it

evolve a just need to exert it out and

dog in a cane switch user user one and

the password the user again this moves

are moved into these slash and the King

who'd share he's able to Mohan he is

able to create the directory as well

because I have refined the permission to

it as read write and execute means full

control permission now if I want to

change the formation I want to change it

to seven five zero four root share and

check your I'll just exit out of this

user again I'll get Logan switch user

user of one and I like to find the

password again this user tries to move

into CD root share he will be able to

because he has the read permission right

here they will just list all the data

but if s trying to create any data any

particular file or directory he won't be

able to even though the last data was

created by him because we have change

the permission we have set the

permission of this particular root share

to read write and execute for the club

so if I want to add enough different

number of users like if I want to add

the trainer as well into this group

because trainer is still others over

here if I check now I have logged in

through the trainer our trainer gain

wants to move into the

would share he won't be able to

permission denied if the route warns

that even the trainer should be able to

get access to this particular data what

he can do is

he can again move into the VI / it is a

/

group and art the other user trainer in

front of attacking

so while you are modifying the file

ensure that you are not affecting the

current file a very carefully you need

to add your users and the user should be

separated by the comma

so you can add a number of users but all

the users should be separated by comma

save it now again the trainer tries to

look at log and CD I'm sorry root

share yeah I need to exit out of it and

again I'm going to get loggin let us CD

CD root share ok so I have to get log

out because they critique Africa console

I have locked him so what I'll do I'll

just show you from the different

terminal from the tty - I am getting

logged in through the trainer pass the

password and now again I'm moving into

the city slash and CD root sure he's

again able to get access to the data

but again as it has the permission only

read/write/execute he won't be able to

create anything so this is what the

permissions generally we have set by

using the users and group members so we

have certainty group members permission

and now here we have seen how we can add

the users into a particular group not

only for the users but the trainer can

also add the particular user into his

group like you can again move into the

group again you can search for your user

account that is your trainer no Trillian

wants to add the user 1 to his group he

can so trainer trip already contains

trainer into it along with that

Whitcombe I'll just add your user 1 and

save it out so this is how generally we

have the we have set like how we can add

the permissions and we have seen how we

can add the users into a particular

group into the next video we are going

to check for like how we can create and

you know change the owners and groups of

a particular directory and a file we

have created so let us move to the next

video
