If you want to add/remove a user only to/from a single secondary group, use gpasswd command

Following your example

Remove tom from sales group
gpasswd -d tom sales

Add tom to printer group
gpasswd -a tom printer

Renato, the -R argument don’t exist for groupmod command in Ubuntu. Try man groupmod.

I don’t know if it’s available from other platforms or not, but I have this command on Arch which seems more intuitive and easier to do:

groupmems -g [group_name] -d [user_name]

For example, if I want to remove sally from group admins:

groupmems -g admins -d sally

Hi,

I have added user to a group called sales using smbldap-usermod -G .
How do I remove this user from the supplementary group. I was once succesful in removing the user by using the command smbldap-usermod -g . But when I give the time id -nG the supplementary group still shows up.
Can you explain why this happens and how to overcome this problem.
Appreciate your help

Cheri

Can anyone tell me command(s) to add an user to a new group without mentioning all the groups the user previously belongs to? (I haven’t gone thru man)

In one line (and nice for scripts):
Add a group: usermod -aG GROUP USER
Remove a group: usermod -G $(id -nG USER| sed -e ‘s/GROUP //’ -e ‘s/ /,/g’) USER

lets say i want to add an existing user to an existing group. when the user belongs to other groups already. what command will i use.

using usermod-g “groupname” user will change the initial gropu of the user and delete him from another group.
usermod -G this will lead from the user being deleted ffrom all other groups except the one sspecified.
