Git的使用记录

Git的使用

配置：

git config 是 Git 的一个强大命令。你可以使用 Git 配置文件来定制 Git 的工作方式。

这个文件存在于初始化 Git 的项目目录（/project/.git/config）或用户根目录（~/.gitconfig）。

如果没有指定配置，Git 会使用其默认设置。

使用如下命令可配置全局设置：

git config --global Axx.Bxx Cxx

~/.gitconfig中会新增如下或对应参数发生相应的变化

[Axx]
    Bxx = Cxx

• 配置名字与邮箱：

  git config --global user.name "name"
  git config --global user.email "xxxx@xx"
  

• 其他配置：

  • 编辑器设置：

    git config --global core.editor "code --wait"
    

    • vi\vim : "vim"
    • vscode :"code --wait"

  • 默认显示简短状态

    git config --global status.short true
    

    默认情况下，git status 命令显示你的项目中的变化，并有很长的细节。它的格式是这样的：

    On branch [branch name]
    Your branch is up to date with ...
    
    Changes not staged for commit:
    (use "git add <file>..." to update what will be committed)
    (use "git restore <file>..." to discard changes in the working directory)
    modified: ...
    
    Untracked files:
    (use "git add <file>..." to include in what will be committed)
    ...
    
    no changes added to commit (use "git add" and/or "git commit -a")
    

    这是一个有指导意义的输出，但有时你只需要一个版本库状态的总结。在 git status 中添加 --short 选项，可以得到一个简短的格式化输出。

    结果会是这样的：

    M [file]
    ?? [file]
    

    “M” 表示已修改，“??” 表示未跟踪。
