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/

It's quite easy, let me demonstrate it with this
example program:

#include curses.h
int main(void)
{
initscr();
cbreak();
noecho();
nonl();

printw(Best highlighting mode of the terminal.\n);
printw(\n);
attrset(A_UNDERLINE);
printw(Underlining\n);
printw(\n);
attrset(A_REVERSE);
printw(Reverse video\n);
printw(\n);
attrset(A_BLINK);
printw(Blinking\n);
printw(\n);
attrset(A_DIM);
printw(Half bright\n);
printw(\n);
attrset(A_BOLD);
printw(Extra bright or bold\n);
printw(\n);
refresh();
return 0;
}
The initsrc() funtion is the key.
I do not have it anywhere in my C files.
But in the manpage. :-)
