pull

The git pull command is used to fetch and integrate changes from a remote repository into the current branch. It is a combination of two commands: git fetch and git merge. First, it fetches the changes from the remote repository, and then it merges those changes into the current branch.

Detailed Explanation

  1. Fetching Changes: The git fetch part of git pull retrieves the latest changes from the remote repository but does not integrate them into your working directory. It updates the remote-tracking branches.

  2. Merging Changes: After fetching, the git merge part of git pull integrates the fetched changes into the current branch. If there are no conflicts, the merge happens automatically. If there are conflicts, you will need to resolve them manually.

  3. Fast-Forward Merge: If the current branch has not diverged from the remote branch, Git will perform a fast-forward merge, simply moving the branch pointer forward.

  4. Three-Way Merge: If the branches have diverged, Git will perform a three-way merge, creating a new commit that combines the changes from both branches.

  5. Rebasing: You can use the --rebase option with git pull to rebase your local commits on top of the fetched commits instead of merging them. This can result in a cleaner project history.

Examples

  1. Pulling Changes from the Remote Repository:

    git pull origin master

    This command fetches the changes from the master branch of the remote repository origin and merges them into the current branch.

  2. Pulling with Rebase:

    git pull --rebase origin master

    This command fetches the changes from the master branch of the remote repository origin and rebases the local commits on top of the fetched commits.
