Automatically add existing user in a new group

[Sébastien N]

Hi,

I want to automatically add exisiting users in a new created group...
The command "groupadd" create the group, but how to include users in it ?

Thanx,
Sebastien.

for this problem
use the sam application
a addition the users to
the group created

Hi,

Try usermod -G group,group,...

Sebastien,

Perhaps the easiest way would be to edit /etc/group and add each of the users manually.

Hi Sebastien,

Can use SAM to assign users to groups or groups to users, as you need.

Hi Sebastien


The best way is to edit /etc/group . Also you log in as that user and run the command groups to know what groups the user belongs to , ie primary and secondary. In case you jsut want to change hte primary membership edit /etc/passwd , always take a backup of the curretn file before modifying it.

hi guys
you can use the command :
-->usermod

but with sam is more easy

if you use the usermod command

insert the option --> " -G"

example :


usermod -G newgroup username

[jim bidebo]

i guess that you want to add the user to an additional group (without changing the primary group in /etc/passwd).

this is how i would do it:
#usermod -G newgroup username

and if you run nis (which i do)you also have to create and push the nis database to all your nisclients:
#/var/yp/ypmake (or if its located at anotherplace on your installation)

The usermod command works properly, but I can not add root to this new group :
# usermod -G newgroup root
Login root is currently in use

I am logged as root...

Any idea ?

[jim bidebo · Accepted solution]

well, its not nessasary to add root to any usergroups since root almost always have full access to the system. but if you want to add root anyways i would use vi (or any editior that you find useable), and then edit /etc/group by hand.

groupname:(password):groupid:list,of,users,separated,by,commas,but,no,comma,at,the,end,root

(password) is hardly ever used, thats why i put it in ().

hello sebastien


you can edit the /etc/group
file ..

see this example:


##vi /etc/group
root::0:root
other::1:root,hpdb
bin::2:root,bin
sys::3:root,uucp
adm::4:root,adm
daemon::5:root,daemon

in this file insert this
row :

newgroup::6:root

now exit save the change

Sebastien,

Since you said "automatically", I don't think there is a way without some fairly elaborate scripting. Editing the group file and using a cut and paste technique is most likely going to be the quickest and simplest method.

I finaly used the usermod command (without root) to obtain a 0 return code.

Thanx to all !
