In today's fast-paced digital world, collaboration and version control are paramount for successful software development projects. Git emerges as a game-changer, revolutionizing the way teams manage their codebase.
What is Git and Why is it Important?
Git, developed by Linus Torvalds, is a distributed version control system designed to track changes in source code during software development.
It allows multiple developers to collaborate seamlessly, manage changes efficiently, and maintain a comprehensive history of revisions.
Key benefits include:
Version Control: Track changes and revert to previous versions easily.
Collaboration: Facilitate teamwork by enabling concurrent work on the same project.
Branching: Experiment with new features without disrupting the main codebase.
Community Support: Leverage a vast community and resources for problem-solving.
Main Branch vs. Master Branch:
| Feature | Main Branch | Master Branch |
| Naming | Also known as "default" or "trunk." | Historically used as the primary branch in Git repositories. |
| Transition | Some organizations have transitioned from "master" to "main." | Traditionally the default branch name in Git repositories. |
| Trends | Increasingly adopted due to inclusivity and neutrality. | Previously used, but now considered outdated by some. |
Creating a New Repository on GitHub: Step-by-Step
Log in to GitHub: Navigate to github.com and log in to your account.
Create a New Repository: Click on the "+" icon in the top-right corner and select "New repository."
Name Your Repository: Give your repository a descriptive name.
Add Description: Optionally, provide a brief description of your project.
Choose Visibility: Decide whether your repository will be public or private.
Initialize with a README: If desired, select this option to create an initial README file.
Create Repository: Click the "Create repository" button to finalize.
Local vs Remote Repositories
Local Repository:
Located on your local machine.
Stores your project's files and commit history.
Enables offline work and experimentation.
Remote Repository:
Hosted on a remote server, often platforms like GitHub, GitLab, or Bitbucket.
Facilitates collaboration among team members.
Serves as a central hub for sharing changes and collaborating.
Connecting Local to Remote Repository:
Initialize Git: Navigate to your project directory in the terminal and initialize Git using
git init.Link Remote Repository: Use
git remote add origin <remote_repository_URL>to link your local repository to the remote one.Push Changes: After making changes locally, commit them using
git commitand push them to the remote repository usinggit push.
🏋️♀️ Exercises
Task-1
Set your user name and email address, which will be associated with your commits.
- Configure User Name: Start by setting your user name associated with your commits using the command
git config --global user.name "your name"
Set Email Address: Next, set your email address to be linked with your commits:
git config --global user.email "your email"
Task-2
Create a repository named "Devops" on GitHub
Connect your local repository to the repository on GitHub.
Create a new file in Devops/Git/Day-02.txt & add some content to it
Push your local commits to the repository on GitHub
