I'd suggest the following line:

	sed -n '/^[[:alpha:]]/ s/[[:space:]].*//p' /etc/mime.types

I tested the sed expression works on Linux and Darwin (macOS sierra).

I'd guess that any future 'ietf-token' starts with alpha character, and
'x-token' always starts with 'x'.

I agree with Jani that we'd rather used some other solution but so far
using sed(1) looks like best tolerable choice there is.

PS: used something like the following to start the emacs to send this email:


  #!/bin/sh
  :; exec "${EMACS:-emacs}" --debug-init --load "$0" "$@"; exit

  (eval-after-load "notmuch"
    (lambda ()
      (setq notmuch-command (concat (file-name-directory load-file-name)
                                    "my-notmuch-remote-command"))
      (setq smtpmail-smtp-server "smtp.gmail.com"
            smtpmail-smtp-service 465
            smtpmail-stream-type 'tls
            smtpmail-debug-info t
            smtpmail-debug-verb t
            message-send-mail-function 'message-smtpmail-send-it)
      ))
  (notmuch)

  ;; Local Variables:
  ;; mode: emacs-lisp
  ;; End:


PPS: first send failed, had to visit

  https://www.google.com/settings/security/lesssecureapps

... it would be nice to know what makes this "less secure" application ...
