To configure your Git account to connect to GitLab on Linux, you can follow these steps:

1. Install Git: If Git is not already installed on your system, run the following command to install it: sudo apt update && sudo apt install git
2. Generate an SSH Key: Use the following command to generate an SSH key. This will provide you with a public key and a private key: ssh-keygen -t rsa -b 4096 -C "[email protected]". Replace [email protected] with the email address you used to register your account on GitLab, and follow the prompts to set the location for saving the key and to set a passphrase.
3. Add the Public Key to GitLab: Copy the contents of the generated public key file. You can print the public key content using this command: cat ~/.ssh/id_rsa.pub. Log in to the GitLab website, navigate to the SSH Keys page in your personal settings (usually found at https://gitlab.com/profile/keys). Paste the public key you just copied into the designated field on that page and save it.
   
4. Configure Global Git Username and Email: Run the following commands to configure your global Git username and email address: git config --global user.name "Your Name" && git config --global user.email "[email protected]". Make sure to replace “Your Name” and [email protected] with your actual name and email address.
5. Test the SSH Connection: Run the following command to test if the SSH connection is successful: ssh -T [email protected]. If the connection is successful, you will receive a welcome message.
6. Start Using Git: Now that you have configured your GitLab account connection, you can use Git commands to clone, commit, and push projects to your GitLab repository.
   • Clone an Existing Repository Locally: git clone [email protected]:your-username/your-repo.git. Replace “your-username” with your GitLab username and “your-repo” with the name of the repository you wish to clone.
   • Create a New Git Repository and Initialize it: Run mkdir your-repo && cd your-repo && git init. Then, add files, commit changes, and push them to your GitLab repository.

I hope these steps will help you successfully configure your Git account to connect to GitLab on Linux. If you have any questions, feel free to ask.
