将使用git config --global更改预先存在的git存储库的设置？

Question

比方说，我做一个回购

cd repo1 
git init 
git config user.name "Jack" 
git config user.email jack@hill.com 

，然后我再拍

cd ../repo2 
git init 
git config --global user.name "Jill" 
git config --global user.email jill@hill.com 

请问我是杰克还是吉尔repo1？ 我认为如果这两个步骤是以相反的顺序完成的话，我会在回购中成为杰克？

Answer 1

无论您运行命令的顺序如何，您都将在repo1和Jill中为repo2。从git config手册页：

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

    $GIT_DIR/config 
     Repository specific configuration file. 

    ~/.gitconfig 
     User-specific configuration file. Also called "global" configuration file. 

    $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. 

    $(prefix)/etc/gitconfig 
     System-wide configuration file. 

Git按此顺序加载这些文件。您的本地存储库.git/config的优先级高于~/.gitconfig，优先于$HOME/.config/git/config，优先于/etc/gitconfig。此外：

All writing options will per default write to the repository specific configuration file. Note that this also affects options like --replace-all and 
--unset. git config will only ever change one file at a time. 

的--global标志不改变每.git/config您的系统上，只是~/.gitconfig。
