git 初始化项目并上传到github

如果还没配置过，需要配置账号信息

git config --global user.name "baymax-collab"
git config --global user.email "[e-mail]"

创建一个新的存储库

git clone [e-mail]:xxxx
cd test
git switch --create main
touch README.md
git add README.md
git commit -m "add README"
git push --set-upstream origin main

推送一个已有的文件夹

cd existing_folder
git init --initial-branch=main
git remote add origin [e-mail]:xxx
git add .
git commit -m "Initial commit"
git push --set-upstream origin main

推送一个现有的Git存储库

cd existing_repo
git remote rename origin old-origin
git remote add origin [e-mail]:xxxx
git push --set-upstream origin --all
git push --set-upstream origin --tags
