grub 配置文件中的语法错误

grub 配置文件中的语法错误

我弄乱了,/etc/grub.d/30_os-prober现在当我运行时,sudo update-grub我得到了这个:

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")

请帮忙!如果你能给我同样的文件来比较一下,看看有什么不同。
或者给我一个不同的解决方案。启动修复不起作用!它有同样的问题!

这是我的文件:

我认为您的导出不应该在 /etc/default/grub 中,而应该在 40_custom 或代码本身中。这就是引发错误的原因。

https://help.ubuntu.com/community/MaintenanceFreeCustomGrub2Screen

这是编辑代码,请参阅此子部分。编辑 /etc/grub.d/05_debian_theme echo " set color_normal=cyan/black"

但这表示它可以命令行或菜单项。

http://www.gnu.org/software/grub/manual/grub.html#Command_002dline-and-menu-entry-commands

14.3 命令行和菜单项命令列表请参阅导出条目

此错误表明在文件的第 66 行/etc/grub.d/30_os-prober,有一个关闭的花括号},但无打开的匹配项。

使用文本编辑器从文件中删除第 66 行。

突出显示和彩色语法很有帮助vim。这样做不仅可以轻松找到第 66 行,而且花括号会显示为白色并以红色突出显示,以指示代码中的错误,因为它没有匹配项。
