removing a user from a group

sigint-ninja · 08-14-2017, 07:59 AM

i know i can add a user to a group by either modifying /etc/group
or using usermod -aG user group

how do you remove a user from a group? i know i can modify /etc/group

but is there a neat command to do this?
thanks

Code:

deluser the-user group-to-remove-from

It is basically the same syntax as

Code:

adduser the-user group-to-add-to

That is one way to do it. Other would be to use gpasswd on systems not blessed with adduser and friends:

Code:

gpasswd -d user group

Or you could (carefully) edit /etc/group

For that option, use vigr, it is safer to edit /etc/group with that. Unless you really know what you are doing.

didn't know about this gpasswd command..hehehe..

I type man gpasswd on RH, and here is it:

Quote:

Usage: gpasswd [option] GROUP

Options:
-a, --add USER add USER to GROUP
-d, --delete USER remove USER from GROUP
-r, --remove-password remove the GROUP's password
-R, --restrict restrict access to GROUP to its members
-M, --members USER,... set the list of members of GROUP
-A, --administrators ADMIN,...
set the list of administrators for GROUP
Except for the -A and -M options, the options cannot be combined.
