“y”在 apt-get install 中代表什么？

Question

任何人都可以澄清sudo apt-get install -y <package>做什么？-y 到底代表什么？

Answer 1

它代表yes，因此将对apt-get命令将生成的任何问题回答yes 。

您可以通过查看命令的手册页来找到命令的选项man。在输出中，man apt-get您可以找到以下部分：

-y, --yes, --assume-yes

       Automatic yes to prompts; assume "yes" as answer to all prompts and
       run non-interactively. If an undesirable situation, such as
       changing a held package, trying to install a unauthenticated
       package or removing an essential package occurs then apt-get will
       abort. Configuration Item: APT::Get::Assume-Yes.
