apt-get - what exactly does apt -get do in linux?

Question

I'm a beginner with Linux. I have on numerous occasions used apt-get, but my question is what exactly does it do? If I'm using apt-get "some random application", what exactly is this doing? I guess I'm confused where it's getting the application to install or where its pulling from..

Answer 1

据我所知，apt-get 调用存储库、某种受支持程序的列表（以及从何处下载它的链接）。您可以添加存储库，这扩展了您可以通过“apt-get”安装的程序列表。这就是我使用它的印象。^^

Answer 2

看看手册页$ man apt-get。它应该回答你的大部分问题。
