git push is a Git command used to upload your local commits to a remote repository. It is used to push changes made to your local repository to a remote repository and update the remote repository’s branch with your local changes. Here is an example:

Let’s say you have made some changes to a local repository and committed those changes. Now, you want to push those changes to a remote repository on GitHub.

First, you need to add a remote repository to your local repository by using the command git remote add origin [remote repository URL].

Once you have added a remote repository, you can push your changes by running the command git push origin [branch name]. For example, if you want to push your changes to the master branch, you will run the command.

git push origin master

or simply

git push

This will upload your local changes to the remote repository’s master branch, making them available to others who are collaborating on the project.
