That's 'cos you are in a new shell.

It's not clear to me what you are actually trying to do, or why you
would need to change a logged-in user's group memberships... something
I am fairly sure is not possible.

Can you explain what you are trying to do in general terms?

I haven't tried this, but maybe you could use exec su - $USER to
replace your running shell with a new shell including the new group? I
don't think that would help with the sockets thing, but it would
prevent stacking up shells. Also look at "man sg", but I think that
will still end up running the command in a new shell.

Regards, K.
