Git is a free and open-source distributed version control system created by Linus Torvalds in 2005. It allows tracking changes to files and coordinating work among teams of developers. GitHub is a web-based hosting service for Git repositories that offers both free and paid plans. Git uses a decentralized model with local repositories that can be synced and shared, supporting thousands of parallel branches. It provides commands for cloning repositories, tracking changes, committing updates, and merging branches.

3. GIT
 Git is FOSS (Free Open Source Software).
 It is Version Control System.
 It can be used to track changes in any set of files
 Was created by Linus Torvalds in 2005 while working on Linux kernel.
 Now maintained by Junio Hamano.
 GIT came into existence because BitKeeper became chargeable.

4. GIT DESIGN AND GOAL
 Speed.
 Simple Design.
 Strong support for thousands of parallel branches.
 Fully distributed.
 Able to handle larges projects like Linux kernel effectively.

6. GITHUB
 GitHub is web-based hosting service for software development projects.
 GitHub offers both paid plans for private repositories, and free accounts for
open source projects.
 As of May 2011, GitHub was the most popular code repository site for open
source projects.

7. VCS AND ITS TYPES

8. COMPANIES & PROJECTS USING GIT

9. BRANCHING MERGING
• Lightweight movable pointer to commits.
• Default branch name: MASTER
• Command: git branch branchname
• For every time you commit, MASTER moves
forward automatically
• Merge multiple sequence of commits into 1
unified history.
• Combine 2 branches
• Command: git merge branchname

10. CLONE
 A git clone makes it easier to copy the project in local machine.
 You retrieve all of the commits from the remote repository, and all of
its branches as well

11. GIT TERMINOLOGY
• Committing - capturing the changes from
your working copy to your local repository.
• Pushing - uploading the captured changes
from your local repository to GitHub.
• Pulling – retrieving data from GitHub.

12. COMMON COMMANDS
 git init – Creates a new repository
 git clone – Copies an existing git repository
 git log – shows the commit logs
 git diff – displays the change that was made
 git status – displays the filenames that has been modified, added and
untracked
 git add – Adds the changes
 git commit – Creates a commit out of the changes that had been done
 git checkout – checking out a commit

13. PROS
• Speed
• Simplicity
• Fully Distributed
• Excellent support for parallel development, support for hundreds of
parallel branches.
• Integrity
CONS
• Huge amount of commands

14. Many Thanks
