What command tells Git to sync your local repository to a remote repository?

The command that tells Git to sync your local repository to a remote repository is "git push." This command specifically uploads your local changes to a remote repository, making them available to others. When you run "git push," it transfers commits from your local branch to the corresponding branch in the remote repository.

Using "git push" allows team members to collaborate by sharing their changes, ensuring that everyone has access to the most up-to-date code. Additionally, if you are pushing to a branch for the first time, Git will automatically create the branch in the remote repository if it does not already exist. This command is critical in workflows that involve collaboration and version control.

The other options do not represent standard Git commands for this functionality. "git sync," "git upload," and "git send" are not recognized commands in Git's command line interface, and therefore do not serve the purpose of syncing local changes to a remote repository.
