Alternative option to upload a file to GitHub without cloning the entire repository

1. Initialize an empty Git repository:

   
   git init my-repository
   cd my-repository
   
   

2. Add a remote for the GitHub repository:

   
   git remote add origin https://github.com/marioseixas/marioseixas.github.io.git
   
   

3. Configure sparse-checkout:

   
   git config core.sparseCheckout true
   
   

4. Specify the directory you want to checkout (if applicable):

   
   echo '_posts/*' >> .git/info/sparse-checkout
   
   

5. Fetch the main branch (change ‘main’ to your target branch if it’s named differently):

   
   git fetch origin main
   
   

6. Checkout the files:

   
   git checkout main
   
   

Git could ask for your GitHub credentials:

• Generating SSH key

• Managing DEPLOY keys

To set up your credentials with SSH for Git on your local machine after generating an SSH key and adding it to your GitHub account, follow these steps:

1. Ensure SSH Agent is Running:

   You need to make sure the SSH agent is running so that it can manage your keys. You seem to have already started the ssh-agent and added your key. If needed again, you can use:

   
   eval "$(ssh-agent -s)"
   ssh-add ~/.ssh/id_ed25519
   
   

2. Test Your SSH Connection:

   Before you try to push your changes to GitHub, you should test your SSH connection. You can do this with the following command:

   
   ssh -T git@github.com
   
   

   You should see a message like “Hi username! You’ve successfully authenticated…”.

3. Configure Git to Use SSH:

   If you haven’t already set Git to use SSH for GitHub, you can do so by changing your remote URL from HTTPS to SSH. Since you just added a deploy key for a specific repository, it’s tied to that repository only. The general command to change the remote URL is:

   
   git remote set-url origin git@github.com:username/repository.git
   
   

   Replace username
