  • It is Distributed Version Control System
  • It is a Command-Line tool
  • It works in a terminal window and gets integrated with PowerShell, Command Prompt terminal

How to start working on git?


Before start using git, you must recall that git is a version control system and git has the additional privilege to keep version tracking locally and remotely. So, if you are configuring git, it will manage the repository locally. So, let get started…

I assume, currently, we don’t have anything linked with the remote repository and solely working LOCALLY.

Step 1: Go to your working directory. Initialize the git repository using the following command.

D:\Learning\git>git init LearningProject

This command will initialize the empty git repository in your current working directory.

Once successfully initialized, git, will create a hidden directory in your working directory called “.git” and a new folder with your defined project name will be created. In our case, it will be “LearningProject”.
Note: This is very very important to understand that the .git hidden folder is the real mechanism that manages all the git related operations on your repository.

For a beginner, it is not really necessary to understand the .git folder in detail but for an experienced person, one should at least know some basics.

The .git hidden folder consists of various sub-folders and files. We may have a super quick look.

hooks: Git hooks folder consists of the scripts that are executed before or after the events.
info: it contains the exclude file. We’ll discuss .gitignore sometime later.
objects: a much important folder that contains saved content as the hash value.
refs: contains references and tags information
config: This file contains all the configuration you would set for your project is saved permanently in this file like username, email, etc.
description: This file contains the data about the repositories which can be seen on GitWeb only
HEAD: The Head file contains the reference to the branch we are currently working on.
Step 2:
Put the content in the project folder. Git does not bother what kind of project are you keeping under it.
This could be any type of file or a complete project irrespective of any programming language.

Stopping this article here and would come back in Part 2 article with followings:

  • Config git for global usage in your system
  • Create a dot net project and apply git commands for version control
