Git is a distributed version control system that allows for both local and remote collaboration on code. It provides advantages like speed, simplicity, integrity, and support for parallel development through features like branching. Common Git commands include git init to start a new repository, git add to stage files, git commit to save changes, git push to upload local work to a remote repository, and git pull to download remote changes. GitHub is a popular hosting service for Git repositories that provides a graphical interface and social features.

Git - Downloading Package (git-scm.com) INSTALLATION GUIDE Windows User ?? Oh ! Or is it MACOS ?? Git - Downloading Package (git-scm.com) Well , if it’s Linux / Unix -- UBUNTU : sudo apt install git OR FEDORA : sudo yum install git
“Let’s Git init”
What is Version Control?
Local Version Control System A local copy is created in my own computer . All versions are stored in folder , sub-folders or A database. That’s the user’s choice. But what if I want to collaborate with people ?? Or what if my computer stops working ??
Centralised Version Control System (CVCS) A Centralized Version Control System , Here we have a server and a client. The server is the master repository that contains all of the versions of the code. To work on any project, firstly user or client needs to get the code from the master repository or server. So the client communicates with the server and pulls all the code or current version of the code from the server to their local machine.
Distributed Version Control System (DVCS) In distributed version control most of the mechanism or model applies the same as centralized. The only major difference you will find here is, instead of one single repository which is the server, here every single developer or client has their own server and they will have a copy of the entire history or version of the code and all of its branches in their local server or machine.
Git and Github There are many words to define git, but it is an open-source distributed version control system in simpler words. Why is git needed? When a team works on real-life projects, git helps ensure no code conflicts between the developers. Furthermore, the project requirements change often. So a git manages all the versions. If needed, we can also go back to the original code. The concept of branching allows several projects to run in the same codebase. GitHub is a Git repository hosting service that provides a web-based graphical interface. It is the largest community in the world. Whenever a project is open-source, that particular repository gains exposure to the public and invites several people to contribute.

Git commands Here is a list of most essential Git commands that are used daily. 1.Git config commandd 2.Git clone command 3.Git add command 4.Git commit command 5.Git status command 6.Git push Command 7.Git pull command 8.Git Branch Command 9.Git Merge Command 10.Git log command But there are many more commands..Let’s start…!
For new git users Git supports a command called git config that lets you get and set configuration variables that control all facets of how Git looks and operates. $ git config --global user.name “GDSC IIIT KOTTAYAM“ $ git config --global user.email “gdsc@iiitkottayam.ac.in" You can check your configuration settings : $ git config -list
Git init The git init command is the first command that you will run on Git. The git init command is used to create a new blank repository. It is used to make an existing project as a Git project. $ git init Example :
Git Status We can list all the untracked files by git status command. $ git status
Git add The git add command is used to add file contents to the index (Staging area) .This command updates the current content of the working tree to the staging area. It also prepares the staged content for the next commit. Every time we add or update any file in our project, it is required to forward updates to the staging area. $ git add <File name>

Git Commit It is used to record the changes in the repository. It is the next command after the git add. Every commit contains the index data and the commit message. Commits are the snapshots of the project. Every commit is recorded in the master branch of the repository. We can recall the commits or revert it to the older version. Two different commits will never overwrite because each commit has its own commit-id. This commit-id is a cryptographic number created by SHA (Secure Hash Algorithm) algorithm. $ git commit -m <Commiting Message>
Git clone In Git, cloning is the act of making a copy of any target repository. The target repository can be remote or local. You can clone your repository from the remote repository to create a local copy on your system. $ git clone <repository URL>
Git ignore In Git, the term "ignore" is used to specify intentionally untracked files that Git should ignore. It doesn't affect the Files that already tracked by Git. The file system of Git is classified into three categories: Tracked: Tracked files are such files that are previously staged or committed. Untracked: Untracked files are such files that are not previously staged or committed. Ignored: Ignored files are such files that are explicitly ignored by git. We have to tell git to ignore such files. $ touch .gitignore
Git Fork A fork is a rough copy of a repository. Forking a repository allows you to freely test and debug with changes without affecting the original project. the forked repository looks like pune2016/GitExample2. At the bottom of the repository name, we can see a description of the repository. At the top right corner, the option fork is increased by 1 number.
Git Push The push term refers to upload local repository content to a remote repository. Pushing is an act of transfer commits from your local repository to a remote repository. Pushing is capable of overwriting changes; caution should be taken when pushing.
Git pull The term pull is used to receive data from GitHub. It fetches and merges changes from the remote server to your working directory. The git pull command is used to pull a repository. Pull request is a process for a developer to notify team members that they have completed a feature. Once their feature branch is ready, the developer files a pull request via their remote server account. Pull request announces all the team members that they need to review the code and merge it into the master branch. $ git pull
Git merge In Git, the merging is a procedure to connect the forked history. It joins two or more development history together. Generally, git merge is used to combine two branches. $ git merge <branchname>
Merge conflicts When two branches are trying to merge, and both are edited at the same time and in the same file, Git won't be able to identify which version is to take for changes. Such a situation is called merge conflict. If such a situation occurs, it stops just before the merge commit so that you can resolve the conflicts manually.
