Ubuntu 通过提示自动执行apt get install dnsmasq

我想自动安装

dnsmasq

，但当我

apt获得install

它时，它会提示我回答一个问题，因为已经存在

/etc/dnsmasq.conf

。就我而言，我不想更换它

我如何能够自动执行此操作，使其不会阻止我的

apt get install

等待用户输入

# apt-get install dnsmasq -y

您可以通过如下方式指定

dpkg

选项来自动执行此操作：

$apt get-o Dpkg:：Options:：=“--force confdef”-o Dpkg:：Options:：=“--force confold”安装dnsmasq-y

这将保留当前的配置文件

为什么需要安装这么多次？您可能希望移动此文件并在安装后再次粘贴它。这可以在shell脚本中完成。它只安装了一次，但配置文件已经存在。我可以手动删除配置，但我想让它更健壮。可能的重复请参见
