Unix-style WebSocket cat (or netcat for websockets).

npm install -g wscat2Usage
$ wscat -husage: wscat [-h] [-v] [-l PORT] [-b] [-k] [-d] [address] Positional arguments: address Optional arguments: -h, --help Show this help message and exit. -v, --version Show program's version number and exit. -l PORT, --listen PORT Start a websocket server on PORT. -b, --binary Use binary WebSockets. -k, --keep-open Do not close the socket after EOF. -d, --deflate Use per-message deflate.

If you ever used nc, wscat works pretty much the same.
Connect to a server

$ wscat localhost:12345Hi there!Hi!It's nice to speak to someone who just dosn't repeat everything I say back at me.Yeah! Isn't it?!Sorry, gotta run...Transfer a file
Server:
$ wscat -b -l 12345 < ~/Desktop/mycat.jpgClient:
$ wscat -b localhost:12345 > igotacat.jpgNote that you can have the client send the file as well, after the connection has been setup wscat does not differentiate between server/client.
Get your bitcoin on
$ echo '{"op":"unconfirmed_sub"}' | wscat -k wss://ws.blockchain.info/invThe -k option is used to keep the socket open after the command has been sent, allowing us to read the continuous stream of bitcoin transactions.
