Setup GitHub SSH Access on a Machine

Pre-requisite: Ensure Git is installed on the machine.

ssh-keygen -t ed25519 -C "your_email@example.com"
Copy SSH Public Key:

Display the public key by running:

cat ~/.ssh/id_ed25519.pub
Copy the entire output.

Add SSH Key to GitHub Account:

Navigate to Settings → SSH and GPG keys.

Click New SSH key, give it a recognizable title, and paste the copied public key.

Clone GitHub Repository Using SSH:

The Role of the Slash (/) in Linux

The Role of the Slash (/) in Linux
In Linux and other Unix-like systems, / is the directory separator — everything starts from the root directory /.
Examples: /etc, /var, /home.

Now here’s the fun part:
According to the POSIX standard, Linux treats multiple consecutive slashes as a single slash — except possibly at the very beginning of a path.

That means:

/home
//home
///home

All point to the same directory.

The One Special Case

Some Unix variants (like older AIX or NFS systems) use // at the start of a path to indicate network namespaces or special mounts, similar to how Windows uses \server\share.
Modern Linux usually ignores this distinction.
