What version of Erlang do I have installed anyway?

Thought erl -v might do the trick but that’s only the major version.

erl -eval '{ok, Version} = file:read_file(filename:join([code:root_dir(), "releases", erlang:system_info(otp_release), "OTP_VERSION"])), io:fwrite(Version), halt().' -noshell

OK, 25.0.2 then.

25.0.2
