If your concern is security-related, using vi -R is not more secure than
printing to stdout -- the data will still persist on the alternate
screen of your terminal or terminal multiplexer (assuming it has one,
which I'm pretty sure tmux does).

What is your real goal here? If you have proper control over your
environment (which is not something that pass can hope to help you
with), your stdout should not be insecure.
