What is the function of the 'git pull' command in Git?

The function of the 'git pull' command in Git is to fetch changes from a remote repository and merge those changes into the current branch of your local repository. When you execute a 'git pull', Git performs two actions in a single command: it first runs 'git fetch', which retrieves the updates from the remote repository, and then it automatically merges those changes into your current working branch.

This is crucial for keeping your local repository up-to-date with the remote repository, especially in collaborative environments where multiple contributors may be pushing changes. By using 'git pull', you can ensure that your local codebase reflects the latest developments made by others.

In contrast, other options describe actions that are unrelated to the core function of 'git pull'. Deleting local branches or creating new branches do not take place through the 'git pull' command, and simply downloading files without merging is not what 'git pull' accomplishes. The command is designed to integrate remote updates directly into your local workflow, emphasizing its role in collaborative development.
