hors "set git remote url" -n 2 -a

Here it is:

- Answer from https://stackoverflow.com/questions/2432764/how-to-change-the-uri-url-for-a-remote-git-repository
You can

git remote set-url origin new.git.url/here

(see git help remote) or you can just edit .git/config and change the URLs there. You're not in any danger of losing history unless you do something very silly (and if you're worried, just make a copy of your repo, since your repo is your history.)


^_^ ==================================================== ^_^

- Answer from https://stackoverflow.com/questions/42830557/git-remote-add-origin-vs-remote-set-url-origin
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
