3. Why learn git??
To manage your Project repository
Sharing your code via github
Contributing to others code

4. Contents
➢ Git Introduction

➢ Git Branching & Merging
➢ Github Introduction
➢ Your app in Github
➢ How to Contribute?

5. Git Is
Open Source
Version control System
Tool for keeping
a history on the
Distributed Revision control state of your
source code
Source code management projects.

6. I'm an egotistical bastard,
and I name all my
projects after myself. First
'Linux', now 'git'
Linus Torvalds

7. Installation
On Linux
sudo apt-get install git
Version of git
Other systems git --version
http://git-scm.com/

8. Git work flow

9. Git Basic Commands
git init //initializes git
git status //prints status of current repo
git diff //prints difference made in files
git add filename //adds file name
git commit -m “Message here :P” //saved!!
git log //history

10. git init
Creates a .git file in current folder
Why??

11. Because
To tell git from where the file must be tracked !!!

12. git add
To add particular files/folders to commit
Examples:
git add .
git add test.c
git add somedirectory/file

13. How do I know which are added ?
Using git status

14. git status
Tells us
about untracked files and files added to commit
How do i know what are the changes?

15. git diff
Tells the changes made in files

16. git commit
git commit -m “message here”
-m => message
git commit -am “message here:P”
-a => To add the modified files and then commit
Message is compulsory !!

17. git log
To show all commits with messages,check sum and
many more
Checksum is always unique to each commit
Can also use gitk, a commit viewer of git

18. How does it work??

19. .gitignore
Tells git what to Ignore

20. Status & Review
✔ Git Introduction
✔ Git Basic Commands
➢ Git Branching & Merging
➢ Github Introduction
➢ Your app in Github
➢ How to Contribute?

21. Git Branching & Merging
git branch //Shows all branches of currrent repo

22. Git creating branches
Git branch branch_name

23. Commit in Branch
git checkout branch_name
Goes to the branch
git add .
git commit -am “Message”

24. Other options
git checkout -b branch_name
Creates new branch and goes to that branch
git branch -d branch name
Deletes the given branch

25. Merging
git merge master branch_name
Used to merge your work with master

26. After merging

27. Oh! I have to go back to last
commit !!!
How do I do that ???

28. git checkout checksum_number
You will have same status as that commit's data !!
Concept:
It goes to a no branch state, one can
make edits and also commit. But then you need to
create that into new branch

29. Status & Review
✔ Git Introduction
✔ Git Basic Commands
✔ Git Branching & Merging
➢ Github Introduction
➢ Your app in Github
➢ How to Contribute?

30. Github

31. Who uses github ???
Many More !!!!

32. GitHub is the best way to collaborate
with others. Fork, send pull requests
and manage all your public and private
git repositories.

33. Creating a new repo

34. Git remote
A remote in Git is basically a way to tell Git where
another version of your repository is.
Then you can ask Git to fetch data from it that you
don’t have yet, or push your commits up to it (if you
have write access).
Git remote add origin https://github.com/username/project.git

35. Fork a repo !!

36. Git clone
git clone new_repo_url your_name
Creates a repo by your_name

37. Adding upstream
git remote add upstream
https://github.com/username/rep.git
Adds remote named upstream for your current repo

38. Fetch
git fetch upstream
Fetches all the changes made to the original repo from
whom you have forked

39. Merge
Git merge upstream/master
Merges the upstream with master branch

40. Git pull
Directly pulls the update from the original repo to your
current working repo

41. There is a lot more to be learnt
Thank you !!
