tailscale-ssh:tldr:59df1

This command is divided into two parts: sudo tailscale up and --ssh=${select}.

1. sudo is a command that allows a user to run a program with the privileges of another user (usually the superuser or root). It is often used to execute commands that require administrative permissions.

2. tailscale is a program used for creating a virtual network between your devices, providing secure connections and access to your resources over the internet. The up command is used to start or connect to the Tailscale network.

3. --ssh=${select} is an option or flag provided to the tailscale up command. It is used to enable secure shell (SSH) access via the Tailscale network. ${select} is a placeholder that should be replaced with a valid SSH target or a specific device identifier on the Tailscale network.

So, when you execute this command, you are using sudo to run the tailscale up command with administrative permissions, and enabling SSH access by specifying the SSH target with --ssh=${select}. You should replace ${select} with the appropriate SSH target you want to connect to over the Tailscale network.
