Chapter 15 Git Command Line Interface (CLI)

15.1 Git Command Workflow

15.2 Git Commands

These are the primary commands for working with git from the commandline.

Important Note - We will use RStudio IDE to abstract away much of the git workflow. RStudio is integrated tightly with git and GitHub, which is a massive productivity booster.

15.2.1 General Commands

git --help - Use help to investigate the available commands.
git --version - Useful for getting the version and checking git installation.

15.2.2 Local Repo Setup

No Remote Repo set up?

git init - Initialize a Local Repo
git commit - Done to initialize (add) your files to the Local Repo.

Remote Repo already set up?

git clone - Clones a remote repo to your local machine. We do this to get software onto EC2 Servers.

15.2.3 GitHub Repo Setup

Important: Make sure a blank repo exists. Then:

git remote add origin https://github.com/user_name/repository.git - Used to link a local repository with a
git push -u origin master - Pushes your initial commit on your Local Repo to the Remote Repo (e.g. GitHub).

15.2.4 Git Workflow

git commit - Adds snapshots of changed files to your Local Repo.
git push - Pushes committed files from your Local Repo to your Remote Repo (e.g. GitHub)
git pull - Pulls the remote repository files to your local repository

15.2.5 Branches

git status - Find the branch you are currently on
git branch - Creates a new branch
git checkout switches the Local Repository to the specified branch
git merge - Merges a branch with the master. This is typically done via “Pull Requests”.
