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

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.
