I can not create origin remotely with remote command:
$ git remote add origin https://github.com/LongKnight/git-basics.git
fatal: remote origin already exists.
To solve the error, I have tried this:
$ git remote -v origin
$ git remote -v show origin
It is not uploading the files from my local repository to the remote:
$ git push -u origin master
fatal: 'origin' does not appear to be a git repository
fatal: Could not read from remote repository.
Please make sure you have the correct access rights and the repository exists.
Does each repository have its own origin?
Solution: I was using the Powershell that came with Github or Git Shell as it is also called to do my tutorial, once I switched to Git Bash it worked fine.
A bit easier:
git remote set-url origin https://github.com/LongKnight/git-basics.git
That will replace the current origin with a new one.
