open(1) works for me, for example,

    $ open -a Emacs ~/.emacs.d/init.el

if *.el has been set Emacs as its default opening App, you can also omit '-a Emacs':

    $ open ~/.emacs.d/init.el

It should work out-of-box, i.e., no configuration needed from the Emacs
side, the following should works for you:

    # Start a fresh Emacs
    $ open -a /Applications/Emacs.app -n --args -Q
    # Open a file
    $ open -a /Applications/Emacs.app ~/.emacs.d/init.el


BTW, emacsclient(1) works as well. After 'M-x server-start' from a GUI
Emacs window:

    $ emacsclient --no-wait ~/.emacs.d/init.el
