I had a reactjs project which I had already uploaded to a GitHub repository, with git init, git add ., git commit and push.
I deleted this repository and created another one where now I want to make the commits in this new one.
How can I do this?
If you have deleted the remote one, on GitHub, and created a new empty one (still on GitHub), you can redirect your existing local commits with:
cd /path/to/existing/local/repository
git remote set-url origin https://github.com/MyAccount/MyNewRepo
git push
You can upload to as many different github/gitlab/bitbucket as you want. Bitbucket being different implementation, slightly different.
This answer focused on github.
inside local repo
git remote add origin ssh-address.
Now the repo can have maximum one "origin" as remote key. For 10 other repository
git remote add origin1 ssh-address1
git remote add origin2 ssh-address2
If you want to replace origin (i.e. the different repo as the main origin)
git remote remove origin
and add remote repo the above way.
Now. for pushing --
git push --set-upstream origin branch-name
