A3.2 附錄 C: Git Commands - Getting and Creating Projects

To take a directory and turn it into a new Git repository so you can start version controlling it, you can simply run git init.

We first introduce this in 取得一個 Git 倉儲, where we show creating a brand new repository to start working with.

We talk briefly about how you can change the default branch from “master” in 遠端分支.

We use this command to create an empty bare repository for a server in 把 Bare Repository 放到伺服器上.

Finally, we go through some of the details of what it actually does behind the scenes in Plumbing and Porcelain.

The git clone command is actually something of a wrapper around several other commands. It creates a new directory, goes into it and runs git init to make it an empty Git repository, adds a remote (git remote add) to the URL that you pass it (by default named origin), runs a git fetch from that remote repository and then checks out the latest commit into your working directory with git checkout.

The git clone command is used in dozens of places throughout the book, but we’ll just list a few interesting places.

It’s basically introduced and explained in 克隆現有的倉儲, where we go through a few examples.

In 在伺服器上佈署 Git we look at using the --bare option to create a copy of a Git repository with no working directory.

In Bundling we use it to unbundle a bundled Git repository.

Finally, in Cloning a Project with Submodules we learn the --recursive option to make cloning a repository with submodules a little simpler.

Though it’s used in many other places through the book, these are the ones that are somewhat unique or where it is used in ways that are a little different.
