- 2. Overview Installing Git and create a GitHub account What is Git? What is GitHub? How does Git work? Quick math examples
- 3. Installing Git and creating an account on GitHub Linux (Debian) command - sudo apt-get install git Linux (Fedora) command - sudo yum install git Mac - http://git-scm.com/download/mac Windows - http://git-scm.com/download/win
- 4. Creating an account on GitHub
- 5. What is Git ? Git is a version control system that keeps track of your changes, allows for collaborative development and allows you to know who made a particular change and when that change was mad. It also allows you to revert changes and go back to a particular state It was created in 2005 by Linus Torvalds (Creator of Linux OS) to aid him in the creation of the Linux Kernel
- 6. Why Git ? Git isnt the only version control software but I (and most people) think its the best. Others includes: Mercurial, Subversion and Perforce
- 7. Key Concepts Snapshots- The way git keeps track of your code history. It records the state of your codebase at a particular point in time. You can decide to go back to any saved snapshot at any point in time. Commit The act of creating a snapshot. A project is made up of multiple commits. It contains the information about the files that changed, a reference to the commit that came before it (called the parent commit), and a hash code name (be3d3ec5069ef6524c80b3ad6b7cbde3cade4e) . It can be a noun or verb I committed my code This guy didnt commit his code on time
- 8. Key concepts (contd) Repositories (Repo) A collection of all the files and the history of those files. It consists of the history of all the commits made to files It can live on your local machine or on a remote server (GitHub) The act of copying a repository from a remote server is called cloning The process of downloading commits that dont exist on your machine from a remote repository is called pulling changes The process of adding your local changes to the remote repository is called pushing changes
- 9. Key Concepts (contd) Branches Like trees, branches allows us split our codebase into single stand-alone functionalities. All commits in git lives on a branch. The main branch in a project is called a master branch. There can be lots of branches but the parent branch is always called a master branch
- 10. Key Concept (contd) Merging -
- 11. What does a typical project look like ?
- 12. So what does a HEAD mean ? A head is a reference to the most recent commit
- 13. What is GitHub ? Website https://www.github.com Founded in 2008 Largest web-based git repository hosting service Allows for code collaboration with anyone online Adds extra functionality on top of Git like UI, Documentation, bug tracking, feature requests, pull requests and contribution charts
