        The command sudo tailscale file cp ${filename} ${select} is a command used to copy a file from one location to another in a Tailscale network. 
Here is a breakdown of the command:
- 
sudo: It is a command used in Unix-like operating systems to run a command with administrative or superuser privileges. It allows the user to execute a command as another user, often the root user.
- 
tailscale: It is a command-line tool that creates a secure network between devices, enabling secure communication and file sharing between them.
- 
file: This command is used in Tailscale to perform file operations like copying, moving, or deleting files within the Tailscale network.
- 
cp: It is short for "copy" and is the specific operation we are performing. It allows us to copy a file from one location to another.
- 
${filename}: It is a placeholder indicating the name of the file you want to copy. You need to replace${filename}with the actual file name or its path.
- 
${select}: It is another placeholder indicating the destination location where the file should be copied. You need to replace${select}with the actual destination location or path.
Therefore, by executing the command sudo tailscale file cp ${filename} ${select}, you will copy the file specified by ${filename} to the destination location indicated by ${select} within the Tailscale network, using administrative privileges.
