[erlang-questions] Hiding user input in escript

[Bob Ippolito]

You can probably get around it by not using escript and just booting up a
compiled beam that does what you want... "erl -noinput -noshell -s
user_drv" seems to start a shell that can handle io:get_password(), so you
could poke inside user_drv and see how to start up user_drv and your script
without the shell.
