为什么解压缩时会创建符号链接？

Question

我有一个存储库，用于存储我所有的点文件，因此可以更轻松地设置新计算机。该存储库还包含用于安装应用程序、修改我的扩展坞、设置首选项、更新 SSH 密钥等的脚本。由于存储库更新了我的 SSH 密钥并修改了我的 git 配置，我发现仅下载存储库会更容易作为 ZIP 文件，然后运行启动脚本（与手动设置 Git 然后克隆存储库）。

但是，我这样做只是为了设置一台新计算机并使用 unzip dotfiles.zip 解压缩存储库，看起来我的一些设置实际上运行（设置符号链接）。

为什么在解压缩存储库时创建了符号链接？

Answer 1

很可能是因为 zip 文件是使用符号链接创建的。

来自zip man page：

-y | --symlinks

For UNIX and VMS (V8.3 and later), store symbolic links as such in the zip archive, instead of compressing and storing the file referred to by the link. This can avoid multiple copies of files being included in the archive as zip recurses the directory trees and accesses files directly and by links.

Why are symlinks created when unzipping?
