github - git - remote add origin vs remote set-url origin

Question

I create a new repository:

git init
echo "# MESSAGE" >> README.md
git add README.md
git commit -m "first commit"

Then I want to push my commit to the empty remote repository created on github so I have to set remote.

What is difference between using following commands ? :

git remote add origin git@github.com:User/UserRepo.git
git remote set-url origin git@github.com:User/UserRepo.git

At the end I perform push:

git push -u origin master

What happens when I call git remote set-url origin just after git init? Does git remote set-url origin create origin? If origin already exists after git init there is no difference between using those commands in my scenario, right?

Answer 1

below is used to a add a new remote:

git remote add origin git@github.com:User/UserRepo.git

below is used to change the url of an existing remote repository:

git remote set-url origin git@github.com:User/UserRepo.git

below will push your code to the master branch of the remote repository defined with origin and -u let you point your current local branch to the remote master branch:

git push -u origin master
