Ry 的 Git 教程：建立您的身份：全局配置

在 Git 能够追踪变更或促进协作之前，它需要一个经过验证的数字签名以将每个操作归因于特定作者。建立全局配置是必要步骤，它将您的身份嵌入到每次提交的元数据中。

Git 使用以下命令为您的工作添加标签。如果没有这些设置，Git 通常会阻止提交过程，以防止出现匿名快照。

git config --global user.name "您的姓名"
git config --global user.email [email protected]

该 --global 标志告诉 Git 将此配置作为您所有仓库的默认值。这些设置存储在中央文件中（通常是 ~/.gitconfig），而不是单个项目文件夹中。

对于 Windows 用户，安装 Git 会提供一个特殊的命令行外壳，称为 Git Bash。您应使用此外壳而非原生命令提示符，以确保命令语法一致并访问标准的 Git 工具。
