Host to Guest clipboard sharing for non-GUI, CLI-only, non-grapical, command line only

From here:

For Whonix-Gateway, one directional clipboard sharing from host to Whonix-Gateway is enabled and secure.

Clipboard sharing in GUI Gateway works. But how can I paste from Host to Guest in non-GUI Gateway?
What I usually do is turning on GUI in Gateway and edit (pasting) in Tor config file. If clipboard sharing works in commandline environment that would be more convenient to work with.
