## Rig description: ##
I've installed Debian in Windows Subsystem Linux (WSL) on Windows 10.

  - **The host** means Windows 10.
  - **The box** means my WSL-Debian box/container.

## Goal: ##
 - I have an SSH key on WSL (my_rsa.pub);
 - I want to copy the contents of that file to the host's clipboard;
 - by running a command in the box (command-line code, not using the mouse).
 
## Explanation: ##
SSH files are very long, and it doesn't make sense to copy them with the mouse cursor.  

I'm also told that Debian doesn't ship with a clipboard: you need to install a clipboard?  So, I don't even know where to begin to look.
