Learn about the version control system, Git, and how it works with GitHub.

Use git push to push commits made on your local branch to a remote repository.

You can use common Git commands to access remote repositories.

Sometimes, Git can't make your change to a remote repository without losing commits. When this happens, your push is refused.

You can turn a folder within a Git repository into a brand new repository.

If you need to manage multiple projects within a single repository, you can use a subtree merge to handle all the references.

The git rebase command allows you to easily change a series of commits, modifying the history of your repository. You can reorder, edit, or squash commits together.

Here's a short tutorial on using git rebase on the command line.

When you perform a git rebase operation, you're typically moving commits around. Because of this, you might get into a situation where a merge conflict is introduced. That means that two of your commits modified the same line in the same file, and Git doesn't know which change to apply.

Git is very permissive about what characters are allowed in branch and tag names. When using Git from a command-line shell, you may need to escape or quote special characters.
