Git push to specific branch with username and password

I need to push my changes to specific branch with username and password. So I found the following command to push directly with username and password.

$ cd demo   //branch name
$ git add .
$ git commit -m "Test commit"
$ git push --repo https://username:password@bitbucket.org/name/repo.git

Here I need to push my changes to demo of the above url with username and password directly so that It will not ask me again. But as per the above command I found its not pushing to any particular branch. I need to commit my changes to that particular branch demo which also present in remote.

Solution

cd demo is not supposed to be a "branch name", just the name of the folder you have clone your repository.

git status would give you the name of the currently checked out branch.
git switch would allow you to change branches.
git branch -avv would show you all local and remote tracking branches

A simple git push would push by default the current branch (for instance 'main') to origin/main, assuming it is already configured that way (a git clone would typically associate main to origin/main)

If origin is not set, you can add it with:

git remote add origin  https://username:password@bitbucket.org/name/repo.git

Although it is best to cache those credentials, using the helper configured locally: check the output of git config credential.helper.

Once you are on the right branch my_branch, the command would be:

git push -u origin my_branch
