- Paste your SSH key into the “Key” field.
- Click Add SSH key to save.
4. Test the SSH Connection
Now that you have set up the SSH key, it’s important to verify that your connection to GitHub is functioning as expected.
To test the connection, run the following command in Git Bash:
bash
ssh -T [email protected]
If your connection is successful, you will receive a message welcoming you to GitHub.
Cloning a Repository from GitHub
With your Git Bash and GitHub account connected, you’re all set to clone repositories. Cloning allows you to create a local copy of a repository stored on GitHub.
Steps to Clone a Repository
- Navigate to the repository you want to clone on GitHub.
- Click the Code button and ensure SSH is selected.
- Copy the provided SSH URL (e.g.,
[email protected]:username/repository.git).
In your Git Bash, navigate to the directory where you want to store the project, then run:
bash
git clone [email protected]:username/repository.git
This command will create a local copy of the repository on your machine.
Pushing Changes to GitHub
After making changes or adding new files in your cloned repository, you might want to push these changes back to GitHub.
Steps to Push Your Changes
- Add Changes: Use the following command to add the modified files:
bash
git add .
This command stages all the changes in the directory.
- Commit Changes: Next, commit your changes with a descriptive message:
bash
git commit -m "Your commit message"
- Push Changes: Finally, push your changes to the GitHub repository:
bash
git push origin main
Replace main with the appropriate branch name if you are working on different branches.
