Script Program Linux

A. Menggunakan Perintah If dan Else

#!  /bin /bash :
clear
echo"Menu Daftar Sembako";
echo"_ _ _ _ _ _ _ _ _ _ _";
echo"1. Ajinomoto";
echo"2. Minyak Goreng";
echo"3. Gula Pasir";
echo"4. Garam Dapur";
echo"5. Telur";
echo"6. Exit";
 
read -p "Pilihan Anda [1-6]:"
If[$pil-eq1];
then
echo"Banyak Barang =";
read jum
let bayar = jum*5000;

elif[$pil-eq2];
then
echo"Banyak Barang =";
read jum
let bayar = jum*20000;

elif[$pil-eq3];
then
echo"Banyak Barang =";
read jum
let bayar = jum*12000;

elif[$pil-eq4];
then
echo"Banyak Barang =";
read jum
let bayar = jum*3000;


elif[$pil-eq5];
then
echo"Banyak Barang =";
read jum
let bayar = jum*24000;


elif[$pil-eq6];
then
exit 0
else
echo"Maaf, tidak tersedia"
exit 1

Fi
echo"Harga Bayar=Rp.$bayar"
echo"Terima Kasih"

Output

B. Menggunakan Script Membuat Windows Sederhana dengan Fungsi Box(   )

#include <ncurses.h>

WINDOW *create_newwin(int height, int width, int starty, int startx);

void destroy_win(WINDOW *local_win);

int main(int argc, char *argv[])

{ WINDOW *my_win;

 int startx, starty, width, height;

 int ch;

 initscr(); /* Start curses mode */

 cbreak(); /* Line buffering disabled, Pass on

 * everty thing to me */

 keypad(stdscr, TRUE); /* I need that nifty F1 */

 height = 3;

 width = 10;

 starty = (LINES − height) / 2; /* Calculating for a center placement */

 startx = (COLS − width) / 2; /* of the window */

 printw("Press F1 to exit");

 refresh();

 my_win = create_newwin(height, width, starty, startx);

while((ch = getch()) != KEY_F(1))

 { switch(ch)

 { case KEY_LEFT:

 destroy_win(my_win);

 my_win = create_newwin(height, width, starty,−−startx);

 break;

 case KEY_RIGHT:

 destroy_win(my_win);

 my_win = create_newwin(height, width, starty,++startx);

 break;

 case KEY_UP:

 destroy_win(my_win);

 my_win = create_newwin(height, width, −−starty,startx);

 break;

 case KEY_DOWN:

 destroy_win(my_win);

 my_win = create_newwin(height, width, ++starty,startx);

 break;

 }

 }

 endwin(); /* End curses mode */

 return 0;

}

WINDOW *create_newwin(int height, int width, int starty, int startx)

{ WINDOW *local_win;

 local_win = newwin(height, width, starty, startx);

 box(local_win, 0 , 0); /* 0, 0 gives default characters

 * for the vertical and horizontal

 * lines */

 wrefresh(local_win); /* Show that box */

 return local_win;

}

void destroy_win(WINDOW *local_win)

{

 /* box(local_win, ' ', ' '); : This won't produce the desired

 * result of erasing the window. It will leave it's four corners

 * and so an ugly remnant of window.

 */

 wborder(local_win, ' ', ' ', ' ',' ',' ',' ',' ',' ');

 /* The parameters taken are

 * 1. win: the window on which to operate

 * 2. ls: character to be used for the left side of the window

 * 3. rs: character to be used for the right side of the window

 * 4. ts: character to be used for the top side of the window

 * 5. bs: character to be used for the bottom side of the window

 * 6. tl: character to be used for the top left corner of the window

 * 7. tr: character to be used for the top right corner of the window

 * 8. bl: character to be used for the bottom left corner of the window

 * 9. br: character to be used for the bottom right corner of the window

 */

 wrefresh(local_win);

 delwin(local_win);

}
