In a previous publication I was talking about the lake of WebSocket support from curl, but it seems I was not using the latest version at this time. I retried that with the 8.20.0 release after reading "websocket in curl" post by Stefan Eissing. It's not "perfect" but it works like netcat.
The first step is to fetch/install the latest curl version for your system, at this time, the 8.20.0 release
$ wget https://github.com/stunnel/static-curl/releases/download/8.20.0/curl-linux-x86_64-glibc-8.20.0.tar.xz
$ tar xvf curl-linux-x86_64-glibc-8.20.0.tar.xz
$ ./curl --version
