Git & GitHub - Share & Update

A beginners guide to git fetch, git pull and git push

In the previous article, we discussed how to inspect and compare branches in Git. In this article, we will see how to retrieve updates from another repository, update the local repository and share your work with others.

Retrieving Updates from Another Repository

When working with a version control system like Git, it is important to keep your local repository up to date with the latest changes from the remote repository. You can do this by using the git fetch command to download the latest changes from the remote repository, but not merge them into your local repository yet. This gives you a chance to review the changes before you merge them.

To fetch changes from a remote repository, you need to specify the remote name and the branch name. For example, to fetch changes from the origin remote and the master branch, you would use the following command:

git fetch origin master

Once you have fetched the changes, you can merge them into your local repository using the git merge command.

Updating local repository

There are two ways to update a local repository with changes made to a remote repository:

  • Using git pull: The git pull command is a combination of git fetch and git merge. It will fetch the latest changes from the remote repository and merge them into your local repository.

  • Using git fetch and git merge separately: You can also use the git fetch and git merge commands separately. This gives you more control over the merging process.

To update a local repository using git pull, you would use the following command:

git pull

To update a local repository using git fetch and git merge, you would use the following commands:

git fetch origin master
git merge origin/master

Which method you use to update your local repository depends on your preferences and the specific situation.

Here are some additional things to keep in mind when retrieving updates from another repository and updating local repos:

  • The git fetch command will not overwrite your local changes. If you have made changes to the local repository that have not been committed, the git fetch command will not affect them.

  • The git merge command can potentially introduce conflicts. This happens when there are changes to the same file in both the local repository and the remote repository. If a conflict occurs, you will need to resolve it before you can merge the changes.

Git push: Share your work with others

git push is a Git command that is used to upload local changes to a remote repository. This can be useful when you are collaborating on a project with other people, or when you want to make your changes available to the public.

To use git push, you need to specify the remote name and the branch name that you want to push. For example, to push the changes from the master branch to the origin remote, you would use the following command:

git push origin master

If you are pushing to a remote repository for the first time, you will need to add the remote name to your local repository using the git remote add command.

Here are a few things to keep in mind when using git push:

  • Make sure that you have committed your changes before you push them.

  • If you are pushing to a remote repository for the first time, you will need to add the remote name to your local repository.

  • If there are conflicts, you will need to resolve them before you can push your changes.

By following the steps outlined in this blog post, you can easily keep your local repository up to date with the latest changes from the remote repository. This will help you collaborate more effectively with others and make sure that your changes are always up to date.
