In one line?

initscr(); cbreak(); noecho(); nonl(); intrflush(stdscr, FALSE); keypad(stdscr, TRUE); start_color();

:-)

The meaning of this "init dance" is explained in the manpage
of curs_inopts - "curses input options":

       cbreak, nocbreak, echo, noecho, halfdelay, intrflush, keypad, meta,
       nodelay, notimeout, raw, noraw, noqiflush, qiflush, timeout, wtimeout,
       typeahead

The start_color() function is mentioned in "man curs_color" and
is only needed if you want to use colors.

For shell scripts, the use of the dialog programs is a good
idea:

	#!/bin/sh
	DIALOG=${DIALOG=/usr/bin/dialog}

This is some kind of "init ncurses in one line". More
examples here: /usr/share/examples/dialog/
