GIT基本使用记录

1、git配置与查看用户名与邮箱命令：

git config --global user.name "your name"
git config --global user.email "your_email@163.com"
git config --global --list
 

如果不设置相关的用户名与邮箱，使用相关commit命令时，会有如下提示：

D:\JavaProjects\imooc-news-dev>git commit -m "first commit"

*** Please tell me who you are.

Run

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

fatal: unable to auto-detect email address (got 'username@username.(none)')

2、基本的使用命令如下：

git add .
git commit -m "first commit"
git branch -M main
git remote add origin git@github.com:AlickLiubc/imooc-news.git
git push -u origin main

遇到如下问题的解决方案参考：

D:\JavaProjects\imooc-news-dev>git push -u origin main

项目根目录下：打开git-bash，使用命令：ssh-keygen -t rsa -C 你的邮箱地址

可以在用户主目录（WINDOWS系统中，例如：C:\Users\用户名\.ssh）里找到.ssh目录，里面有id_rsa和id_rsa.pub两个文件，将id_rsa.pub里面的内容复制粘贴到github站点的SSH公钥中即可。
