This document provides an overview of the version control system Git. It discusses what version control is, describes centralized and distributed version control systems, and focuses on explaining what Git is, how to set it up and use basic commands like add, commit, branch, merge, and push. It also covers inspecting and comparing code as well as sharing and updating projects with Git.

1. Version Control System
GIT
Version control is a system that records changes to a file or
set of files over time so that you can recall specific versions
later

3. Agenda
● Version Control System
● What is Git
● Setup Git
● Create New Project
● Basic Snapshotting
● Branching & Merging
● Sharing & Updating Projects
● Inspection & Comparison
● Patching
● Ref Git - Reference (git-scm.com)

4. Version Control Systems
❏ Easily Management collaboration on a project by avoiding frustration of
swapping files.
❏ Ability to have unlimited number of developers working on the same code
base.
❏ Easily revert back to your files if something happened.
➢ Centralized Version Control Systems
➢ Distributed Version COntrol SYstems

5. Centralized Version Control Systems
❏ These systems (such as CVS, Subversion, and Perforce) have a single server that
contains all the versioned files, and a number of clients that check out files from
that central place
❏ Everyone knows to a certain degree
what everyone else on the project is doing.

6. Distributed Version Control Systems
❏ In a DVCS, clients don’t just check out the latest snapshot of the files; rather, they
fully mirror the repository, including its full history.
❏ Every clone is really a full backup of all the data.

7. What is GIT?
● GIT is free and open source distributed system with the emphasis on speed
and data integrity.
● Git thinks about its data more like a stream of snapshots.

8. Setup Git?
❏ Download git from Git - Downloads (git-scm.com)
Setup the download file
❏ To check the version git --version
❏ To View all the Settings
❏ To Change your identify
❏ To change default branch Name

9. Creating Project?
❏ To init the project git init
❏ To add all files git add .
❏ To commit the files git commit -m “Palash: Project init”
❏ To push the changes in github git remote add origin <repo-url>
❏ To push code git push origin master
❏ To clone the repository git clone <repo-url>

10. .git Directory Structure

11. GIT State Operation?
❏ There are 3 states in git (Modified, Staged, Committed)
❏ Modified means that you have changed the file but have not committed it to your
database yet.
❏ Staged means that you have marked a modified file in its current version to go into
your next commit snapshot.
❏ Committed means that the data is safely stored in your local database.

12. GIT State Operation?

13. Basic Command
❏ ADD: To add file git add <fileName> git add .
❏ STATUS: To show the status git status
-s short, -b branch, –show-stash, –long
❏ DIFF: To show the diff git diff
❏ COMMIT: To commit git commit -m <Message>
❏ NOTES: To add the notes git notes add -m 'Tested-by: Palash' <commit Ref>
To show notes git show -s <commit ref>
❏ RESTORE: To restore the files git restore hello.c
❏ RESET: Reset current HEAD git reset --hard HEAD

14. Branching & Merging
❏ BRANCH: To show all branch git branch -a
To create branch git branch dev
To Delete branch git branch -d dev, remote git push origin -d dev
❏ CHECKOUT: To checkout git checkout <branchname>
❏ MERGE: To merge git merge <branchName>, git merge origin/staging
❏ MERGETOOL: To resolve the conflict git mergetool
❏ LOG: To show logs git log
❏ STASH : To changes in a dirty working directory git stash
❏ TAG: Create, list, delete or verify a tag object signed with GPG git tag test
❏ WORK TREE: Reset current HEAD git reset --hard HEAD

15. Sharing and Updating Projects
❏ FETCH: To download objects and refs from the repository git fetch -a
❏ PULL: Fetch from and integrate with another repository or a local branch
git pull origin <branchname>
❏ PUSH: Update remote refs along with associated objects git push origin
<branch>
❏ REMOTE: Manage set of tracked repositories git remote
❏ SUBMODULE: Initialize, update or inspect submodules
git submodule add https://github.com/chaconinc/DbConnector

16. Inspection & Comparison
❏ SHOW: To Show various types of objects git show
❏ LOG: Fetch from and integrate with another repository or a local branch
git log
❏ DIFF: Show changes between commits, commit and working tree, etc git
diff
❏ DIFFTOOL: Show changes using common diff tools git difftool
❏ SHORTLOG: Summarize git log output
git shortlog

17. Visual Studio Git Features
❏ Show details in Demo

18. Be a professional, care about your code
