  echo "2. Restart"
  echo "3. Exit Menu"
  read –p "Enter your choice: " choice
  
  case $choice in
  
      1) shutdown now
         ;;
      2) shutdown –r now
         ;;
      3) break
         ;;
      *) continue
         ;;
  
  esac

  while true
  do
    echo "1. Shutdown"
    echo "2. Restart"
    echo "3. Exit Menu"
    read –p "Enter your choice: " choice
  
    case $choice in
  
        1) shutdown now
           ;;
        2) shutdown –r now
           ;;
        3) break
           ;;
