How do I add a tag to a GitHub repository from the terminal window using a mac?

Question

基本上我想添加一个标签，但是我只能使用命令行，我已经尝试过git tag -m

Answer 1

That's easy:

git tag my-tag
git push --all-tags

In case you have not pushed your commits yet, you would also want to bring them upstream as well, because pushing the tags does not also push the commits:

git push

That's it.
