Git

Git is a distributed version control system widely used for source code management.

Install Git on Debian

Install Git
sudo apt-get update
sudo apt-get install -y git

Add Git to ToolingBins

Symlink git
cd ~/ToolingBins
ln -s /usr/bin/git git

Create an SSH Key for Git Services

SSH keys allow secure authentication with Git services for pulling and pushing code.

To generate a new SSH key pair:

Generate SSH key
ssh-keygen -t ed25519 -C "your_email@example.com"

Explanation of parameters:

  • -t ed25519: Specifies the type of key to create. ed25519 is a modern, secure algorithm recommended for most users. You can use rsa for compatibility, but ed25519 is preferred.
  • -C "your_email@example.com": Adds a comment to the key, typically your email address, to help identify the key later.

After running the command:

  • You will be prompted for a file location (press Enter to accept the default: ~/.ssh/id_ed25519).
  • You can set a passphrase for additional security (optional).

The public key will be saved as ~/.ssh/id_ed25519.pub.
Add this public key to your Git service (GitHub, GitLab, etc.) under SSH keys to enable SSH-based authentication.

Then to allow your system to use that ssh key to connect to your services you need to add it to your ssh-agent

Add SSH key to ssh-agent
eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_ed25519
