git branch
- 将本地仓库初始化,并完成第一次 commit
- 在 GitHub 创建一个远程仓库,初始为空,准备接受本地推送
GitHub 远程仓库创建之后的提示页面,给出了要完成从本地仓库到远程仓库推送(第二种方法)的示例代码:
git remote add origin https://github.com/Alowree/Fonts.git
git branch -M main
git push -u origin main
Explain the function of
git branch -M main
and why it is necessary before the push command.
The command git branch -M main
forcefully renames the current branch to main
.
git branch
: The command for branch-related operations.-M
: A shortcut for--move --force
. It renames the current branch. If a branch namedmain
already exists, it will be overwritten.
Why it's necessary before pushing:
When you create a new repository locally with git init
, the default branch name might be master
(depending on your Git version). However, new repositories created on GitHub now default to using main
.
To avoid a mismatch and to align your local repository with the modern standard used by GitHub, you rename your local master branch
to main
.
If you didn't do this, your local default branch would be master
while the remote's default would be main
. When you tried to run git push -u origin main
, it would fail with an error like "src refspec main does not match any" because you don't have a local branch named main
to push. Renaming it ensures your local and remote branches have the same name, allowing for a clean initial push and proper tracking.
总结一下,示例代码中剩下的三步:
- 给本地仓库添加远程仓库
- 为本地仓库的当前分支强行重新命名为
main
- 推送至远程仓库
