curl - How to read websocket response in linux shell

Question

Writing a bash script to connect to GDAX's Websocket Feed at wss://ws-feed.gdax.com but curl doesn't seem to support this as I get

curl "wss://ws-feed.gdax.com"
curl: (1) Protocol "wss" not supported or disabled in libcurl

Answer 1

Assuming you have node installed, I would give wscat a shot; it is simple, intuitive, and powerful. Otherwise, @Pavel's answer has an abundance of venerable websocket client alternatives.

# install
npm install -g wscat

# use
wscat -c "wss://ws-feed.gdax.com"
