There’s gtk-gnutella. It has --shell flag. You need to write commands. There’s no TUI. If you just want to share from there, there’s no issue, but if you want to search and download from the search you are better using the normal gtk-gnutella (without the --shell) flag.

I’ve tried to use the shell mode, long time ago and it was complicated. So i never did it. It was long time ago.
