默认的14.04 / etc / default / grub文件内容是什么？

9

我像这个家伙一样也意外地重击了我的/etc/default/grub文件，尽管我是通过使用>而不是>>在配置脚本中完成此操作的。所提供的答案看起来与我在14.04桌面默认grub文件中所记得的不同...它包含什么？

教鱼...是否可以使用一些资源/方法自己找到答案，而不必重新安装14.04只是为了找出答案？

14.04 grub2

重新安装14.04太多了；重新安装grub会更容易;）

如果您将来要进行任何修改/etc/default/grub，请先使用进行备份sudo cp /etc/default/grub /etc/default/grub-backup。这意味着，如果将来将其存储起来，则还原起来会更容易-大多数配置文件在其内部/etc和其他地方也一样。

对于“ 教学捕鱼... ” 这一部分，仍有可能的答案：

...可以自己找到答案，而不必重新安装14.04只是为了找出答案？

我/etc/default/grub在http://packages.ubuntu.com/#search_contents上进行了搜索：

抱歉，您的搜索没有结果

除去第一个/etc，因此搜索第二个源包名称/default/grub。结果很成功：

/usr/share/grub/default/grub grub2-common

我的Ubuntu机器上仍然有此文件吗？

$ sudo ls /usr/share/grub/default/grub
/usr/share/grub/default/grub

或者，例如：

$ sudo [ -f /usr/share/grub/default/grub ] && echo Found || echo Not\ found
Found

事实上，它在那里。

它的内容是什么？

$ sudo cat /usr/share/grub/default/grub
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.

# Uncomment to get a beep at grub start

您可能已经发现，与Rinzwind的答案的输出相比，还有另一条明显的不同线：

#GRUB_HIDDEN_TIMEOUT=0
