Appending groups to a user

For example, if testuser is a member of  group1 and group2, and you need to add the user to group3, the command would be:

usermod -G group1,group2,group3 testuser

If you mistakenly ran:

usermod -G group3 testuser

Then testuser would be removed from group1 and group2 and only be a member of group3.
