git commit -m "first commit"
git remote add origin
git push -u origin master

2.push an existing repository from the command line

git remote add origin

3.create a new branch on the command line

git push -u origin iss114

4.merge a branch on the command line

5.delete a remote/local branch on the command line

附注:提交代码报错时，很大几率用到的命令git remote rm origin.
