Therefore in this article, I will discuss everything regarding Git and GitHub so that you can understand it clearly. Table of Contents Introduction Installation Linux Debian / Ubuntu (apt-get) Fedora (dnf/yum) Windows Mac Basic GitHub terms Basic Git Command Demonstration GitHub special repository Conclusion Introduction Git is a source code management technology used by DevOps. It is a free and open-source version control system used to efficiently manage small to huge projects. Git is a version control system. Version control is a file manager that maintains track of changes to your projects over time and keeps a complete history of whatever you're working on. It allows many developers around the globe to work together on the same project at the same time. GitHub is a site that hosts Git repositories, but it also has its own features. It is a web-based graphical interface for Git, which is a command-line application. Each project has access control and numerous collaborative capabilities, such as wikis and rudimentary task management tools. It is the home of 56 million ( September 2020 ) developers around the globe which Microsoft currently owns. Installation Every operating system has its own steps to install Git.

The major reason for this is to adapt to other people's repositories to meet your needs. Fork : When you create a new repository, it comes with a default development branch. Main : It is a text file that contains information about other files in a repository. It is usually a basic plain text file called Read Me that serves as documentation. Readme : A Repository is where tour work will be stored in a directory or storage space. This is sometimes abbreviated as "repo" by GitHub users. Repository : If you want your repository to be genuinely open source, you'll need to license it so that others can use, modify, and distribute it. License : It allows you to announce a change made by you in the branch. It is a way for a developer to let the rest of the team know when they've finished a feature. Pull request Basic Git Command : The git init command creates a new Git repository. This command creates a subdirectory in the current working directory, which contains all of the necessary Git metadata for the new repository. git init .git : The git clone command is used to create a copy of a specific repository or branch within a repository. git clone : This git command is used to create a new branch for a specific repository. git branch <branch-name> : The git checkout command lets you navigate between the branches created by the git branch. git checkout <branch-name> : It is the first command in a chain of operations that directs Git to "save" a snapshot of the current project state into the commit history. It is used to tracks your file and changes in Git git add : The git commit command takes a snapshot of the current state of the project's changes. git commit : This command is used to upload git commits to a remote repository like Github git push The power of Open Source is the power of the people. The people rule. ~ Philippe Kahn Demonstration To create a new folder, you need to use the below command. mkdir demo-folder To navigate to your newly created folder, use the below command. cd demo-folder To create a new file, you need to the below command. touch index.js Use the below command to see untracked changes in the file. index.js git status To add , use the command below. index.js git add index.js To commit your changes use the below command git commit -m "added index.js file" To add your remote origin link, use the command below git remote add origin main https://github.com/suhailkakar/demo To push your code to GitHub, you can use the below command git push -u origin GitHub special repository GitHub offers a special repository by your username, which should contain a and it will show in your GitHub profile, just like mine: readme.md If you want a similar look, you can fork my repository . here Conclusion ⌛ I hope you found this article helpful.
