FAQ011

FAQ012

What is the difference between "fetch" and "pull" in Git? In Git, "fetch" and "pull" are two related but distinct commands:

  1. Fetch:

    • The git fetch command is used to retrieve changes from a remote repository without merging them into your local branches.
    • It downloads new branches and updates existing ones from the remote repository but does not automatically merge the changes into your working directory.
    • Fetching allows you to see what changes are available in the remote repository and decide when to integrate them into your local branches.

  2. Pull:

    • The git pull command is a combination of git fetch and git merge. It fetches changes from the remote repository and automatically merges them into the current local branch.
    • Pull is a convenient way to update your local branch with the changes from the remote repository in a single command. However, it may automatically create a merge commit, which can affect the commit history.

In summary, while both "fetch" and "pull" involve retrieving changes from a remote repository, "fetch" is more explicit and allows you to inspect the changes before merging, whereas "pull" automatically merges the changes into your local branch.
