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.

Git is a version control system used to track changes to source code over time. It allows developers to collaborate by managing changes from multiple developers. GitHub is a hosting service for Git repositories that provides tools for collaboration. The key steps to sync a local Git repository with GitHub are to initialize and commit to the local repo, connect it to a remote GitHub repo, and push and pull changes between the local and remote repos.
Git Bash is a command line interface that allows you to interact with Git, a version control system that tracks changes in your code and lets you collaborate with other developers. Git Bash is based on a popular Unix shell called Bash, and it works on Windows operating systems. With Git Bash, you can create and manage Git repositories, stage and commit your code, push and pull from remote servers, create and merge branches, and much more. In this article, I will give you an introduction to Git Bash and show you how to use some basic commands. ¹²³

Git is a free and open source distributed version control system designed by Linus Torvalds in 2005 to handle everything from small to large projects with speed and efficiency. It allows for tracking changes to code, collaborative work, and reverting to previous versions of code. GitHub is a site for hosting Git repositories online that adds features like documentation, bug tracking, and code review via pull requests. Common Git commands include git init to initialize a repository, git add to stage changes, git commit to save changes to the project history, and git push to upload changes to a remote repository.
CSE 390 Lecture 9 - Version Control with GITPouriaQashqai1
Version control systems like Git allow developers to track changes to files over time. Git stores snapshots of files in a local repository and remote repositories can be used for collaboration. The basic Git workflow involves modifying files, staging changed files, and committing snapshots of the staged files to the local repository. Status and diff commands allow viewing changes between the working directory, staging area, and repository. Good commit messages are important for documenting changes over time.
Git is a distributed version control system that allows developers to work collaboratively on projects. It works by creating snapshots of files in a project over time. Developers can commit changes locally and then push them to a remote repository to share with others. Key Git concepts include repositories, commits, branches, cloning repositories from remote locations, and commands like push, pull, commit, log and diff to manage changes.
Beginner Workshop for Student Developers - Tratech-presentation.pdfGDSCKNUST
Version control allows tracking changes to code over time and collaboration between developers. Git is a version control tool while GitHub is a platform that integrates with Git. This document discusses setting up Git locally and linking a Git repository to a GitHub account for collaboration and backup of code. Key steps include installing Git, configuring user settings, initializing a Git repository for a project, adding and committing files, and pushing the local repository to GitHub to sync changes and make the code accessible to others.
In this project, you will learn to use some of the team” features o.docxbreaksdayle
In this project, you will learn to use some of the “team” features of your preferred IDE (Eclipse or NetBeans). We will use the “Git” source code control system to allow all members of the class to work on the same project at the same time, and then to merge in your changes. This is a “real-world” way of working on code; few developers work on real projects by themselves. (And even then, version control is often useful and used.)
The project is a very simple one. The source file SayHello.java has a main method you need to edit. Add a statement to main to greet the class by displaying a unique string (so your contribution differs from other students'), which should include your name. (You are free to add additional output if you desire, such as a quote or joke.)
I have created a Git repository you can access from the
GitHub.com
. This repository contains the initial version of
SayHello.java
, a
README.md
file, a
.gitignore
file, and a bunch of other files needed for a Maven project. (There are also some Eclipse IDE project files in there, to make importing into Eclipse easier.) The initial version has a greeting from the instructor you can use as a model for your own additions. (While it is okay to be a little creative, say by adding a joke or quote, just don't go overboard and add too much!) The URL of the repo is shown below, in the step-by-step directions for each IDE. You can also view the
project's website
(generated by Maven from the initial version).
Following the directions below, you will create a GitHub account for yourself, and
clone
the current repo. (IDEs generally require a local repo to work with as well.)
You use the Git repo just like any other Java project. When you are done making a set of changes (for this project you only need to add a single line to
main
), you must
commit
your changes. That updates the local repository from your IDE's version. Next, you
Push
your changes to the class' GitHub repo. During this step you may discover another student has committed some changes after you had checked out the project. If so, you will need to
merge
your changes into the new version. You can also
update
your local copy of the project, over-writing your files with the latest ones from the repository, and make your change again.
You can perform other Git related operations with Eclipse or NetBeans. (Generally, I find the Git interface for NetBeans more intuitive than Eclipse.) It is expected that students will explore some of these operations. Eclipse assumes you may have multiple projects per repo, and thus creates a project top-level folder within the top (root) of the repo. NetBeans doesn't do that by default, but it is perfectly happy either way, so I set up the GitHub class repo using the Eclipse conventions.
Another issue is that Eclipse doesn't easily import non-Eclipse projects with existing sources. It can be done, but it was easier to create the default Eclipse project files ...

The simplified electron and muon model, Oscillating Spacetime: The Foundation...RitikBhardwaj56
Discover the Simplified Electron and Muon Model: A New Wave-Based Approach to Understanding Particles delves into a groundbreaking theory that presents electrons and muons as rotating soliton waves within oscillating spacetime. Geared towards students, researchers, and science buffs, this book breaks down complex ideas into simple explanations. It covers topics such as electron waves, temporal dynamics, and the implications of this model on particle physics. With clear illustrations and easy-to-follow explanations, readers will gain a new outlook on the universe's fundamental nature.
2. Version control systems
Version control (or revision control, or source control) is all
about managing multiple versions of documents, programs, web
sites, etc.
Almost all “real” projects use some kind of version control
Essential for team projects, but also very useful for individual projects
Some well-known version control systems are CVS, Subversion,
Mercurial, and Git
CVS and Subversion use a “central” repository; users “check out” files,
work on them, and “check them in”
Mercurial and Git treat all repositories as equal
Distributed systems like Mercurial and Git are newer and are
gradually replacing centralized systems like CVS and Subversion

3. Why version control?
For working by yourself:
Gives you a “time machine” for going back to earlier versions
Gives you great support for different versions (standalone,
web app, etc.) of the same basic project
For working with others:
Greatly simplifies concurrent work, merging changes
For getting an internship or job:
Any company with a clue uses some kind of version control
Companies without a clue are bad places to work

4. Why Git?
Git has many advantages over earlier systems such as
CVS and Subversion
More efficient, better workflow, etc.
See the literature for an extensive list of reasons
Of course, there are always those who disagree
Best competitor: Mercurial
I like Mercurial better
Same concepts, slightly simpler to use
In my (very limited) experience, the Eclipse plugin is easier to
install and use
Much less popular than Git

5. Download and install Git
There are online materials that are better than any that I could
provide
Here’s the standard one:
http://git-scm.com/downloads
Here’s one from StackExchange:
http://stackoverflow.com/questions/315911/git-for-beginners-the-
definitive-practical-guide#323764
Note: Git is primarily a command-line tool
I prefer GUIs over command-line tools, but…
The GIT GUIs are more trouble than they are worth (YMMV)
5
6. Introduce yourself to Git
Enter these lines (with appropriate changes):
git config --global user.name "John Smith"
git config --global user.email jsmith@seas.upenn.edu
You only need to do this once
If you want to use a different name/email address for a
particular project, you can change it for just that project
cd to the project directory
Use the above commands, but leave out the --global
6
7. Create and fill a repository
1. cd to the project directory you want to use
2. Type in git init
This creates the repository (a directory named .git)
You seldom (if ever) need to look inside this directory
1. Type in git add .
The period at the end is part of this command!
Period means “this directory”
This adds all your current files to the repository
1. Type in git commit –m "Initial commit"
You can use a different commit message, if you like
7
8. Clone a repository from elsewhere
git clone URL
git clone URL mypath
These make an exact copy of the repository at the given URL
git clone git://github.com/rest_of_path/file.git
Github is the most popular (free) public repository
All repositories are equal
But you can treat some particular repository (such as one on Github) as
the “master” directory
Typically, each team member works in his/her own repository,
and “merges” with other repositories as appropriate
8
9. The repository
Your top-level working directory contains everything about
your project
The working directory probably contains many subdirectories—source
code, binaries, documentation, data files, etc.
One of these subdirectories, named .git, is your repository
At any time, you can take a “snapshot” of everything (or selected
things) in your project directory, and put it in your repository
This “snapshot” is called a commit object
The commit object contains (1) a set of files, (2) references to the
“parents” of the commit object, and (3) a unique “SHA1” name
Commit objects do not require huge amounts of memory
You can work as much as you like in your working directory, but
the repository isn’t updated until you commit something
9
10. init and the .git repository
When you said git init in your project directory, or
when you cloned an existing project, you created a
repository
The repository is a subdirectory named .git containing
various files
The dot indicates a “hidden” directory
You do not work directly with the contents of that directory;
various git commands do that for you
You do need a basic understanding of what is in the repository
10
11. Making commits
You do your work in your project directory, as usual
If you create new files and/or folders, they are not tracked by Git unless you
ask it to do so
git add newFile1 newFolder1 newFolder2 newFile2
Committing makes a “snapshot” of everything being tracked into your
repository
A message telling what you have done is required
git commit –m “Uncrevulated the conundrum bar”
git commit
This version opens an editor for you the enter the message
To finish, save and quit the editor
Format of the commit message
One line containing the complete summary
If more than one line, the second line must be blank
11
12. Commits and graphs
A commit is when you tell git that a change (or addition) you
have made is ready to be included in the project
When you commit your change to git, it creates a commit object
A commit object represents the complete state of the project, including all
the files in the project
The very first commit object has no “parents”
Usually, you take some commit object, make some changes, and create a
new commit object; the original commit object is the parent of the new
commit object
Hence, most commit objects have a single parent
You can also merge two commit objects to form a new one
The new commit object has two parents
Hence, commit objects form a directed graph
Git is all about using and manipulating this graph
12
13. Working with your own repository
A head is a reference to a commit object
The “current head” is called HEAD (all caps)
Usually, you will take HEAD (the current commit object), make
some changes to it, and commit the changes, creating a new
current commit object
This results in a linear graph: A B C … HEAD
You can also take any previous commit object, make changes to
it, and commit those changes
This creates a branch in the graph of commit objects
You can merge any previous commit objects
This joins branches in the commit graph
13
14. Commit messages
In git, “Commits are cheap.” Do them often.
When you commit, you must provide a one-line
message stating what you have done
Terrible message: “Fixed a bunch of things”
Better message: “Corrected the calculation of median scores”
Commit messages can be very helpful, to yourself as
well as to your team members
You can’t say much in one line, so commit often
14
15. Choose an editor
When you “commit,” git will require you to type in a
commit message
For longer commit messages, you will use an editor
The default editor is probably vim
To change the default editor:
git config --global core.editor /path/to/editor
You may also want to turn on colors:
git config --global color.ui auto
15
16. Working with others
All repositories are equal, but it is convenient to have one central
repository in the cloud
Here’s what you normally do:
Download the current HEAD from the central repository
Make your changes
Commit your changes to your local repository
Check to make sure someone else on your team hasn’t updated the central
repository since you got it
Upload your changes to the central repository
If the central repository has changed since you got it:
It is your responsibility to merge your two versions
This is a strong incentive to commit and upload often!
Git can often do this for you, if there aren’t incompatible changes
16
17. Typical workflow
git pull remote_repository
Get changes from a remote repository and merge them into
your own repository
git status
See what Git thinks is going on
Use this frequently!
Work on your files (remember to add any new ones)
git commit –m “What I did”
git push
17
19. Keeping it simple
If you:
Make sure you are current with the central repository
Make some improvements to your code
Update the central repository before anyone else does
Then you don’t have to worry about resolving conflicts or
working with multiple branches
All the complexity in git comes from dealing with these
Therefore:
Make sure you are up-to-date before starting to work
Commit and update the central repository frequently

20. The End

When I say I hate CVS with a passion, I have to also
say that if there are any SVN [Subversion] users in
the audience, you might want to leave. Because my
hatred of CVS has meant that I see Subversion as
being the most pointless project ever started. The
slogan of Subversion for a while was "CVS done
right", or something like that, and if you start with
that kind of slogan, there's nowhere you can go.
There is no way to do CVS right.
