git - 无法更改 git config 用户名，立即重置

Question

如果我这样做:

 git config --global user.name "My New Name"

它可以工作一小会儿。如果我这样做:

cat ~/.gitconfig

我可以在 user.name 属性中看到正确的值。

但是，只要我打开一个新的终端窗口或执行 git 提交，旧名称就会被重置。

我正在使用 ssh。有没有缓存机制？

(注意这不是关于 GitHub 用户名，而是关于每次提交的作者姓名)

FILES section of the git config documentation显示配置值的来源。

If not set explicitly with --file, there are four [or five] files where git config will search for configuration options:

1. $(prefix)/etc/gitconfig
   System-wide configuration file.
2. $XDG_CONFIG_HOME/git/config
   Second user-specific configuration file. If $XDG_CONFIG_HOME is not set or empty, $HOME/.config/git/config will be used. Any single-valued variable set in this file will be overwritten by whatever is in ~/.gitconfig. It is a good idea not to create this file if you sometimes use older versions of Git, as support for this file was added fairly recently.
3. ~/.gitconfig
   User-specific configuration file. Also called "global" configuration file.
4. $GIT_DIR/config
   Repository specific configuration file.
5. $GIT_DIR/config.worktree
   This is optional and is only searched when extensions.worktreeConfig is present in $GIT_DIR/config.

关于它们的优先级

The files are read in the order given above, with last value found taking precedence over values read earlier. When multiple values are taken then all values of a key from all files will be used.

如果您使用 git config 或 git config --local 修改存储库的配置(这将修改 $GIT_DIR/config ，所以要么 .git/config 用于带有工作树的 repo 或 config 在裸 repo 中)，并通过 git config --global(存储在 ~/.gitconfig 中)将在该存储库中不可见。

要进行快速完整性检查，请运行两个命令。

git config --global user.name
git config --local  user.name
