创建 git 仓库:
mkdir test
cd test
git init -b "main"
touch README.md
git add README.md
git commit -m "first commit"
git remote add origin https://gitee.com/dearyang/test.git
已有仓库?
cd existing_git_repo
git remote add origin https://gitee.com/dearyang/test.git
设置其他仓库地址（重点）
git remote set-url --add origin <其他仓库地址>
推送
git push -u origin "main"
