git fetch [options] [remote] [refspec...]

git fetch retrieves commits, files, and references from a remote repository, updating your local repository's knowledge of remote branches without modifying your working directory or current branch. This makes it a safe operation for staying synchronized with remote changes.When you fetch, Git downloads all new commits and objects from the remote and updates remote-tracking branches (like origin/main). Your local branches remain unchanged, allowing you to review remote changes before integrating them. This is the crucial distinction from git pull, which fetches and then automatically merges.The prune option (-p) removes references to remote branches that no longer exist on the server. Shallow fetches with --depth limit history download, useful for CI/CD environments. The --unshallow option converts a shallow clone to a complete repository.
