Git Configuration

Configure Git

1. Configure Git globally:

git config --global -e

2. If you haven't set your default editor, configure it:

sudo update-alternatives --install /usr/bin/editor editor /usr/local/bin/nvim 100
sudo update-alternatives --config editor

3. Insert the following configuration into your global .gitconfig file:

[user]
  name = Example Name
  email = [email protected]
[core]
  editor = nvim --wait
  autocrlf = input
[init]
  defaultBranch = master

4. Use SSH instead of HTTP to avoid repeated use of GitHub tokens.

Generate SSH Key Pairs

1. Generate SSH key pairs:

ssh-keygen -t ed25519 -b 4096 -C "[email protected]"

2. Copy the public key to your GitHub account.

3. Edit your ~/.ssh/config file:

nano ~/.ssh/config

4. Add the following content to the file:

Host *
  AddKeysToAgent yes
  IdentityFile ~/.ssh/id_ed25519

5. Start the SSH agent:

eval "$(ssh-agent -s)"

6. Add the SSH key to the agent:

ssh-add ~/.ssh/id_ed25519

7. Verify your GitHub connection:

ssh -vT [email protected]

8. Finally, Clone your repository using SSH:

git clone [email protected]:github_username/repo
