git pull

The git pull command is used to fetch changes from a remote repository and merge them into your current local branch. It's essentially a combination of git fetch followed by git merge. You'll use it when collaborating with others on a project that's stored in a remote repository. When someone else makes changes and pushes them to the repository, you can use git pull to bring those changes into your local copy.

Here's a basic example of how to use git pull:

git pull origin master

In this example, origin is the name of the remote repository (this is the default name Git gives to the remote you cloned from), and master is the name of the branch you want to pull from. When you run this command, Git fetches the changes from the master branch in the origin repository, and then merges those changes into your current branch.

If the current branch is set to track a remote branch (which is usually the case if you've cloned a repository), you can omit the repository and branch:

git pull

When you run this command, Git will fetch changes from the tracked branch and merge them into your current branch.

Note that git pull automatically merges the changes into your current branch. If you want to review the changes before merging them, you can use git fetch to fetch the changes and git merge to merge them when you're ready. Or you can use git pull --no-commit to fetch and merge changes but not commit them immediately, giving you the chance to review the changes first.
