Commands for Remotes

1. List all your remote repositories and show their URLs:

   git remote -v
   

2. View details about a remote repo named origin, including all the remote branches and local tracking branches for origin:

   git remote show origin
   

3. (Pushing a new branch) You commit some files to the dev-foo branch and try to "push" them to Github, but it fails as shown here:

   cmd>  git checkout dev-foo
   cmd>  git push
   fatal:  The current branch dev-foo has no upstream branch. 
   

   Explain this error.

   This error occurs because the local branch dev-foo does not have an associated remote tracking branch. We can fix this by using the command git push -u origin dev-foo to establish a tracking relationship.

4. The command to push dev-foo to origin as a new remote branch on origin is:

   git push origin dev-foo
   

5. (Create a local tracking branch for a remote branch) The remote repository (origin) has a branch named e2e-test that you don't have in your local repository.
   The command to create a new local branch as a copy of the remote e2e-test branch that tracks the remote branch is:

   git checkout -b e2e-test origin/e2e-test
   

6. The command to change the URL of the remote "origin" to a new URL, such as https://hostname/newuser/new-repo-name, is:

   git remote set-url origin https://hostname/newuser/new-repo-name
   

   This situation occurs when:

   • you change the name of a repo on Github
   • you transfer ownership of a Github repo to someone else
   • you move from Github to another hosting site, like Bitbucket
   • you want to switch from the https to the ssh protocol (the remote URL is different)

7. To create a second remote repository for your local repo, the command to add a remote named "bitbucket" with the URL "https://bitbucket.org/your-username/git-commands" is:

   git remote add bitbucket https://bitbucket.org/your-username/git-commands
   

   • Note: you must create an empty repo on Bitbucket. This command just adds it as a remote, it won't create the remote repo.
