Синтаксическая ошибка в конфигурационном файле grub

Я испортил /etc/grub.d/30_os-prober, и теперь, когда я запускаю sudo update-grub, я получаю это:

Generating grub.cfg ...
Found linux image: /boot/vmlinuz-3.5.0-23-generic
Found initrd image: /boot/initrd.img-3.5.0-23-generic
/etc/grub.d/30_os-prober: 66: /etc/grub.d/30_os-prober: Syntax error: "}" unexpected (expecting "fi")

Пожалуйста, помогите! Если вы можете дать мне тот же файл, чтобы сравнить и посмотреть, что отличается.
Или дай мне другое решение. Ремонт багажника не работает! У него та же проблема!

Вот мой файл:

#! /bin/sh
