A systems administrator wants to update their local Git repository with the latest changes from the origin remote. They need to download all new data, such as commits, files, and references, but they do not want to automatically merge these changes into their current working branch to avoid disrupting their ongoing work. Which of the following commands should the administrator use to achieve this?
The correct command is git fetch. This command downloads commits, files, and references from a remote repository into the local repository, updating the remote-tracking branches (e.g., origin/main). Crucially, it does not modify the user's local working branch, allowing them to inspect the fetched changes before deciding to integrate them with git merge or git rebase.
git pull is incorrect because it combines git fetch with an immediate git merge or git rebase. This would automatically attempt to integrate the downloaded changes, which contradicts the scenario's requirement.
git merge is incorrect because its purpose is to combine different branches that already exist in the local repository. It does not download any new data from a remote source.
git rebase is also incorrect as it is used to rewrite commit history by replaying one branch's commits on top of another. Like merge, it operates on local commits and does not fetch data from the remote repository.
