Simply run the following command to add an existing user to an existing group:
sudo adduser {USER-NAME-HERE} {GROUP-NAME-HERE}
sudo adduser vivek www-data
Verify it with the help of id command:
id vivek
Add a new user to the www-data group
In this example, add a new user called vivek to the www-data group, enter:
sudo useradd -g www-data vivek ### set the password for vivek user ### sudo passwd vivek

id vivek groups vivek
The group name www-data is the user’s initial login group i.e. vivek has been added to www-data primary group only.

sudo groupadd vivek sudo useradd -g vivek -G www-data,ftp vivek sudo passwd vivek

Thats a good tip >< Is there no command for that?
Yes… I’m spent some time with chmod / chown manipulation, before understand it =)

Rubbish… complete and utter rubbish.
to add a user to www-data group with Ubuntu at least that is:
sudo adduser ‘NameOfUserYouWantAdded’ www-data
and done!
not exist “ftp” group
Maybe It’s cause you don’t have/don’t need an ftp group (eg. you don’t have an ftp service installed or misconfigured)
