and no combination will work as far as i can see because the ()'s create
a subshell. what this means is that the shell creates a child process
and runs the command in there - and environment variables go down to
children but never up to parents.
so, your best bet is:
cmd1 && (cmd2 > cmd2.out &); var=$(cat cmd2.out); rm cmd2.out
