Git Overview
 Centralized Version Control Systems :
A single server that contains all the versioned files, and a number of clients that
check out files from that central place.
 Cons :
If centralized server goes down for an hour, then during that hour nobody can
collaborate at all or save versioned changes to anything they’re working on.

4. 4
(Cont..)
 Distributed Version Control Systems
Clients don’t just check out the latest snapshot of the files: they fully mirror the
repository.
 Pros :
If any server dies, and these systems were collaborating via it, any of the client
repositories can be copied back up to the server to restore it.

5. 5
(Cont..)
Difference between Git and any other VCS
 Git stores data as snapshots of the
project over time
 Nearly every operation is local
 Other systems tend to store data as
changes to a base version of each file
 CVCS where most operations have that
network latency overhead

6. 6
(Cont..)
 Git has three main states
1. Committed - The data is safely stored in your local database
2. Modified - Changed the file but have not committed it to your database yet
3. Staged - Marked a modified file in its current version to go into your next commit snapshot

7. 7
(Cont..)
 Each file in working directory can be in one of two states
1. Tracked - Files that were in the last snapshot; they can be unmodified, modified,
or staged.
2. Untracked - Everything else

8. 8
Branching
$ git commit -m 'initial commit of my project'
 Single commit repository data.

9. 9
(Cont..)
 Git object data for multiple commits

10. 10
(Cont..)
 A branch in Git is simply a lightweight movable pointer to one of these commits. The default
branch name in Git is master
 Every commit, it moves forward automatically

11. 11
(Cont..)
 Create a new branch
 A new pointer at the same commit
$ git branch testing

12. 12
(Cont..)
 Pointer HEAD
 HEAD file pointing to the branch you’re on

13. 13
(Cont..)
 Switch to an existing branch
 $ git checkout testing
 The branch that HEAD points to
moves forward with each commit

14. 14
Merging
 A simple three-way merge
 Git automatically identifies the best common-ancestor merge base for branch merging

15. 15
Remote Repositories
 Clone the repository
 $ git clone URL
 Fetching from remotes
• $ git fetch [remote-name]
 Pushing to remotes
• $ git push [remote-name] [branch-name]

16. 16
(Cont..)
 Clone the repository
 A Git clone gives own master branch and origin/master pointing to origin’s master branch.

17. 17
(Cont..)
 Fetching from remotes

18. 18
Key features of Git
 Speed
 Simple design
 Strong support for non-linear development (thousands of parallel branches)
 Fully distributed
 Able to handle large projects like the Linux kernel efficiently (speed and data size)

19. 19
Key Git Commands
Git Commands Example
$ git init $ git init Project1
$ git add $ git add FileName1
$ git status
$ git diff --staged
$ git commit –m “message”
$ git rm $ git rm FileName1
$ git reset HEAD $ git reset Head FileName1.gs
$ git log
$ git clone $ git clone URL
$ git help config

20. 20
GitHub Overview
 GitHub is an open source version control system
 It is a Git repository web-based hosting service
 Distributed revision control
 Source code management
 Open-source development community
 Mobile integration
 Collaboration features ( wiki, task management, bug tracking, and feature requests )
 Key steps
• Creating a repository
• Forking a repository
• Social

21. 21
Gists Overview
 Gist is a Git repository
 Gists are a great way to share your work
 Share single files, parts of files, or full applications
 Gists can be forked, and cloned
Types of gists
 Public gists
 Secret gists
 Anonymous gists
