Demystifying Git: A Comprehensive Guide

Introduction

The software development industry has completely changed because to Git. It's a distributed version control system that streamlines teamwork, records code alterations, and equips developers with the tools they need to work more productively. Understanding Git is crucial whether you're a seasoned developer or just getting started. In this post, we'll take a deep dive into Git and examine its fundamental ideas, fundamental commands, and recommended practices.

What is Git

Linus Torvalds, the man responsible for the Linux operating system, developed the distributed version control system (DVCS) known as Git. It's intended to keep track of changes made to source code while software is being developed, enabling smooth collaboration between different engineers. Git is resilient and appropriate for both small and large projects since, in contrast to centralized systems, it doesn't depend on a central server.

Keys

1. Repository (Repo): A repository is a location where all of the files and previous versions of your project are kept. It functions as a folder that houses the source code for your project and all of the modifications made to it over time.

2. Commit: A commit is a representation of your project at a specific moment in time. Each commit includes a distinct identifier and a commit message that summarizes the modifications that were performed.

3. Branch: A parallel version of a repository is called a branch. Until you're ready to merge the changes, you can create branches to work on new features or bug fixes without affecting the main project.

4. Clone: By making a local clone of a repository, you can work on the project on your own.

5. Push and Pull: Fetching and merging changes from a remote repository into your local copy is what is meant by pulling, whereas pushing is the act of submitting your changes to a distant repository.

Basic Git Command

1. git init: Creates a new Git repository in your project directory.
2. git clone [repository URL]: Makes a local copy of a remote repository.
3. git add [file]: Stages changes for the next commit.
4. git commit -m "[message]": Commits your staged changes with a description.
5. git status: Displays the status of your working directory.
6. git log: Shows a history of commits in the current branch.
7. Git branch: Lists all of the branches in your repository, highlighting the active branch.
8. git checkout(branch):Switches to a different branch with git checkout [branch].
9. git pull: Merges changes from a remote repository into your local branch by feting them from the repository.
10. git push: Uploads your local branch to a distant repository via git push.
