Can you explain how the 'git pull' command works and its impact on the local repository?

The git pull command performs two operations in sequence:

1. git fetch — downloads changes from the remote repository to the local one, updating references to remote branches.
2. git merge — merges these changes with the current local branch.

As a result, git pull updates the local repository by pulling the latest commits from the remote and attempting to automatically merge them with local changes.

If conflicts arise during the merge, they need to be resolved manually.

Example:

git pull origin main

This command updates the current branch by pulling changes from the main branch of the remote repository origin.

Thus, git pull helps synchronize the local repository with the remote, ensuring the code is up to date.
