How to add existing user to an existing group?

I want to add the Apache user (www-data) to the audio group. I've read the man page for useradd, but I'm not having any luck. I'm running xubuntu 11.10. Here's what I'm doing:
$ sudo useradd -G audio www-data
useradd: user 'www-data' already exists
If I leave out the -G option, bash, prints the help info for useradd:
$ sudo useradd audio www-data
Usage: useradd [options] LOGIN
Options: -b, --base-dir BASE_DIR base directory for the home directory...
It's not clear to me from the man page what options I should use to make this work.

The useradd command will try to add a new user. Since your user already exists this is not what you want.
Instead: To modify an existing user, like adding that user to a new group, use the usermod command.
Try this:
sudo usermod -a -G groupName userName
The user will need to log out and log back in to see their new group added.
The
-a(append) switch is essential. Otherwise, the user will be removed from any groups, not in the list.The
-Gswitch takes a (comma-separated) list of additional groups to assign the user to.

@con-f-use, if you can runsudo login -f YOURUSERNAME, it will start a new shell session. Use theidcommand to verify that the new session is in the correct set of groups. However, this isn't "global" - it doesn't apply to terminals that are already open. So, really, logging out is the best option, where possible

After adding to a existing user:
usermod -a -G group user
You may need to logout and login to get the groups permissions from /etc/group.

On Ubuntu, since logging in as root is not enabled, users in the sudo group can elevate privileges for certain restricted commands. Any restricted command must be prepended with sudo to elevate privilege.
sudo usermod -a -G group userwill add the existing user user to a supplemental group named group. The user's primary group will remain unchanged.

I'm posting this as an answer because I don't have enough reputation to comment. As @dpendolino's mentioned, for the effects of this command to persist:
sudo usermod -a -G groupName userName
...you need to logout/login again.
However, if you need a shortcut to start using your new group membership immediately (and you have the correct sudo privileges) I have found this work-around:
$ sudo su -
# su [userName]
$ groups
Explanation:
sudo su -will give you a root shell
su [userName]returns you to a shell with your user
groupswhen run now will show the group you added with theusermod -aGcommand
In my case I was trying to add the 'docker' group to my user
Before:
$ groups
userName adm cdrom sudo dip plugdev lpadmin sambashare wireshark lxd
After:
$ groups
userName adm cdrom sudo dip plugdev lpadmin sambashare wireshark lxd docker

@Tejendra's comment seems to presuppose that using useradd is desirable/mandatory to answer OP's question; Perhaps this answer is just missing words to indicate that adduser/deluser is a better alternative.

After adding to a existing user:
usermod -a -G group user
You may need to logout and login to get the groups permissions from /etc/group.

On Ubuntu, since logging in as root is not enabled, users in the sudo group can elevate privileges for certain restricted commands. Any restricted command must be prepended with sudo to elevate privilege.
sudo usermod -a -G group userwill add the existing user user to a supplemental group named group. The user's primary group will remain unchanged.

I'm posting this as an answer because I don't have enough reputation to comment. As @dpendolino's mentioned, for the effects of this command to persist:
sudo usermod -a -G groupName userName
...you need to logout/login again.
However, if you need a shortcut to start using your new group membership immediately (and you have the correct sudo privileges) I have found this work-around:
$ sudo su -
# su [userName]
$ groups
Explanation:
sudo su -will give you a root shell
su [userName]returns you to a shell with your user
groupswhen run now will show the group you added with theusermod -aGcommand
In my case I was trying to add the 'docker' group to my user
Before:
$ groups
userName adm cdrom sudo dip plugdev lpadmin sambashare wireshark lxd
After:
$ groups
userName adm cdrom sudo dip plugdev lpadmin sambashare wireshark lxd docker
