Thanks for response. Can this be a catch?

Does not work as well.

Let me rephrase:
    $ ERL_FLAGS="-sname eunit" erl -pa . -s eunit test foo
according the documentation of ERL_FLAGS, should be equivalent to
    $ erl -pa . -s eunit test foo -sname eunit

However, these two cases behave differently.

Regarding Ulf's response, if "-s eunit test" blocked until completion,
the second case would not work, and at least, -sname would not be
parsed? However, we see the node name.

Do I misunderstand what ERL_FLAGS does? As far as I see, it should alter
the command line before any module execution. As we see from printed
node name, the command line is parsed.
