Master: git init

---

In this video, we'll take a closer look at git init.

In reality, you probably won't use the additional options for git init.

Instead, let's take a closer look at what git init does.

When we used git init, Git told us it created a .git directory.

Let's list the contents of this directory by running:

ls -la .git

We see Git created several files and directories within .git.

This directory effectively serves as a database. Git uses it to store information about the current state of the repository as well as its history.

As such, if you remove this directory, you destroy the Git repository.

Let's demonstrate this by running:

rm -rf .git

We can see my prompt changed and we receive an error when we run git status.

Removing the .git directory will not effect any of the other files or directories. But by destroying the Git repository we lose all of the history.

It's unlikely you'll want to do this. Nonetheless, I think it's important to know how to undo commands.

So, if you ever run git init in the wrong directory, simply remove the .git directory.
