delete a branch in local $ git push origin --delete master # delete the remote branch master, which is easier to remember than git push origin : ``` ``` git remote set-url origin https://a-boy@github.com/a-boy/playmath #远程地址中带上用户名,Git 1.9以前的版本就会不再回应403 Forbidden而是询问密码 git remote set-url --add origin git@gitee.com:ahmeng/playmath.git #
