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 - 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”.
