Hi,

I want to add more than one group to existing user, what command should I use?

Thanks

usermod

See
man usermod
info usermod

FYI, You can also just add them to the group by editing /etc/group

usermod works perfect, but it wouldn't let me add more than one group in the same command

usermod oracle -G oracle, dba

wouldn't work, I have to do it in two steps

usermod oracle -G oracle

then

usermod oracle -G dba

why is that?

From man usermod:

Code:

       -G group,[...]
              A list of supplementary groups which the user is also a member of.  Each group is separated from  the
              next  by a comma, with no intervening whitespace.  The groups are subject to the same restrictions as
              the group given with the -g option.  If the user is currently a  member  of  a  group  which  is  not
              listed, the user will be removed from the group

Can you figure out what you did wrong now?

What's the errors you get? Make sure the group actually exists as well.

Looking at the code that you used

Quote:

usermod oracle -G oracle, dba

it looks like you have a space between the comma and dba. I could be wrong, but I think that you have to omit whitespace.

The correct syntax is

usermod -G <group> <user>

or

usermod -G <group>,<group> <user>
