On wsl(ubuntu), I can do scp somefile ubuntu:somepath, and use tab completion for the somepath, as I use keys to ssh.
But I cant do this in reverse. On remote ubuntu I do scp somefile wsl:, and then press tab, it will show
-bash: warning: command substitution: ignored null byte in input.
Config on remote ubuntu for host wsl is just using windows ip and windows username. key is added to C:\Users\username\.ssh\authorized_keys and I changed default shell to wsl in windows, using this microsoft guide. That registry key is now C:\Windows\System\wsl.exe. Plus, I can ssh into wsl from ubuntu without password.
Although I can go to wsl and do scp ubuntu:somefile somepath, but it's annoying to open another shell just for a command and then forget to close it.
