Git is a source control management tool that allows developers to work collaboratively on projects. It tracks changes to code by storing snapshots of files and allows developers to focus on specific features by working on branches. The document provides steps to install git, set it up locally, and explains basic commands like add, commit, status, branch and merge. It also discusses strategies for using git like committing often, using descriptive messages, and working on separate branches from the stable master branch.

git is a Source Control
Management application
It keeps track of your code!

git allows you to focus
on the feature you’re
writing

How git works

http://git-scm.com/about/staging-area

git init
Initializes a git repository
in current folder

git add .
Adds file . to the staging area
( . means current folder and all files inside )

git commit –m ‘initial commit’
Commits files added to staging area
( -m adds commit message )

git status
Shows current status of
working directory

http://git-scm.com/book/en/Git-Basics-Recording-Changes-to-the-Repository

Branching encourages
a few things
Frictionless Context Switching
Feature Based Workflow
Disposable Experimentation

http://git-scm.com/about

git branch name
Create new branch to work from

git checkout branchname
Sets working tree to branchname

git checkout –b branchname
Create and checkout into branchname

git merge branchname
Merges committed changes made in
branchname with current branch

Two basic actions
git push git pull
Pushes changes to Pulls changes from
remote repo remote repo

git clone
Use git clone to duplicate
a remote repository locally

Submodules!
Submodules allow you to keep separate
sections of your code under source control
( repos within repos )

git submodule add
repository
path/to/location
Adds submodule located at repository to
path/to/location within project

.gitignore
Use .gitignore to prevent files
from being added to the repo

Master branch is stable
ONLY.
Always develop on a separate branch

Branch naming:
initials/feature-name
ns/some-cool-feature

git rebase branchname
Updates current branch with changes made
in another

Git introduces the concept of a local repository where the entire project history is stored locally, unlike SVN which routes all changes through a remote repository. With Git, changes are committed as changesets rather than whole file versions, and branching/tagging are inherent parts of distributed version control. Pull requests allow sharing and merging changes between remote and local repositories through fetch, merge, and rebase operations.

Version Control Systems with git (and github) as an exampleGaurav Kumar Garg

Version control systems are programs or software to manage the source code of computer programs. Most of the open source projects are now hosted on github. So learning about git and github is very much necessary to learning and start contributing to the open source projects. In this presentation I hope to get the audience introduced to the basics of version control systems and learn the basics of git. http://shdlr.com/conferences/talk/20332

Version Control System - GitCarlo Bernaschina

Git is a version control system that allows developers to work collaboratively on projects. It enables features like parallel development, tracking changes, and merging work from different developers. Git started as a way to manage the Linux kernel project and provides a distributed and open source alternative to other version control systems. It works by tracking changes to files, allowing developers to commit changes with a message, and merge changes from different branches of development.

Git is a version control system that records changes to files over time. It was created by Linus Torvalds for development of the Linux kernel and is now widely used by software developers. Some key points about Git include that it is distributed, allows non-linear development through branches, and can handle large projects with millions of lines of code and thousands of commits from hundreds or thousands of contributors. The basic Git workflow involves initializing a repository, making changes, staging files, committing changes to the local repository, and pushing commits to a remote repository. Common commands include git init, git add, git commit, git push, git pull, and git log.

Introduction to Git and Github Max Claus Nunes

setting up a repository using GITAshok Kumar Satuluri

This document provides an overview of common Git commands for setting up and working with repositories. It explains how to initialize a new repository with `git init`, clone an existing repository to obtain a local copy with `git clone`, and configure user settings and aliases with `git config`. Key points are that `git init` is usually only run once per project to set up the central repository, while developers typically clone repositories to obtain local copies, and `git config` is used to define author information and customize settings.

Version control systems allow recording changes to files over time and reverting files back to previous states. Git is an open source distributed version control system initially created by Linus Torvalds for Linux kernel development. Git stores project snapshots over time as differences from a base version of files and allows fully local operations without needing network access. Basic Git commands include add, commit, branch, checkout, merge, push and pull to manage changes to a local or remote repository.
