git clone is a command that creates a copy of a repository, including all its branches and history, in a new directory.

Here’s an example:

git clone https://github.com/username/repo.git

This will create a copy of the repository repo owned by username on GitHub, and save it to a new directory called repo in your local machine.

You can also use git clone to clone a repository from a remote server using SSH, or to clone a specific branch.
