//切换到本地的项目根目录下
git add .
git commit -m "first commit"
git remote add origin https://github.com/lkdghzh/go-ex.git//输入账号密码之后  git remote --verbose就可以看到 *master
git pull origin master --allow-unrelated-histories//加上--allow-unrelated-histories 避免fatal: refusing to merge unrelated histories
git push origin master

删除远程多余的文件

例如 .idea的文件夹，以为第一次没添加到ignore而被提交上去了。现在想删除远程上的.idea

git rm -r -n --cached .idea  //-n 列出想删的目录或者文件
    rm '.idea/go-ex.iml'
rm '.idea/misc.xml'
rm '.idea/modules.xml'
rm '.idea/vcs.xml'
rm '.idea/workspace.xml'
git rm -r --cached .idea
rm '.idea/go-ex.iml'
rm '.idea/misc.xml'
rm '.idea/modules.xml'
rm '.idea/vcs.xml'
rm '.idea/workspace.xml'
 git status
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

        deleted:    .idea/go-ex.iml
        deleted:    .idea/misc.xml
        deleted:    .idea/modules.xml
        deleted:    .idea/vcs.xml
        deleted:    .idea/workspace.xml
 git commit -m  "git rm -r -n --cached .idea"
git push origin master
