Lesson No 2 Setting Up git and gitHub
Step 1: Installing and Configuring Git
Getting started with Git is an essential step for any developer or project manager. In this tutorial, we'll walk through the process of setting up Git on your local machine and configuring it to work seamlessly with your projects.
Installing Git
The first step is to download and install Git on your computer. Git is available for Windows, macOS, and Linux, and you can find the appropriate version for your operating system on the official Git website (https://git-scm.com/downloads). Follow the installation instructions for your platform, and once the installation is complete, you're ready to move on to the next step.
Configuring Git
After installing Git, you need to configure it with your personal information. Open a terminal or command prompt and run the following commands to set your name and email address:
git config --global user.name "Your Name"git config --global user.email "your_email@example.com"
These settings will be used to identify you as the author of any commits you make in your Git repositories.
Step 2: Initializing a Git Repository
Now that Git is installed and configured, you can start using it to track your project files. The first step is to create a new Git repository or initialize an existing project directory as a Git repository.
Creating a New Git Repository
To create a new Git repository, navigate to the directory where you want to store your project files and run the following command:
git init
This will create a new .git directory in your project folder, which will serve as the repository for your project files.
Initializing an Existing Project
If you have an existing project that you want to start tracking with Git, simply navigate to the project directory and run the git init command. Git will create the necessary files and directories to start tracking your project.
Step 3: Tracking Project Files
Once you have a Git repository set up, you can start tracking your project files. Git allows you to add, modify, and remove files from the repository, and it will keep track of all the changes you make.
Adding Files to the Repository
To add a file to the Git repository, use the following command:
git add filename.txt
This will stage the file for the next commit. You can also use git add . to add all the files in the current directory to the staging area.
Committing Changes
After adding files to the repository, you can commit the changes with the following command:
git commit -m "Commit message"
The -m flag allows you to add a commit message, which is a brief description of the changes you've made. Commit messages are important for keeping track of the history of your project and making it easier to understand the changes over time.
Checking the Status of the Repository
To see the current status of your Git repository, including any files that have been modified or added, use the following command:
git status
This will show you which files have been added, modified, or deleted, and which files are currently being tracked by Git.
Step 4: Viewing Commit History
As you continue to work on your project and make changes, Git will keep track of all the commits you've made. You can view the history of your commits using the following command:
git log
This will display a list of all the commits made to the repository, including the commit message, the author, and the date of the commit. You can also use additional options with the git log command to customize the output, such as git log --oneline to display a more concise view of the commit history.
Conclusion
In this tutorial, you've learned how to set up Git on your local machine, initialize a Git repository, track project files, and view the commit history. Git is a powerful tool that can help you manage your projects and collaborate with others more effectively. By mastering these basic Git commands, you'll be well on your way to becoming a more efficient and productive developer.
