Bash Websocket Client

A simple websocket client written in bash. It sets up a websocket connection, performs a compliant handshake, and sends messages of up to 126 bytes (I'll work on longer messages eventually). I think it does proper masking and framing per RFC 6455.

There's a few constants in the script because running it will all the correct parameters via CLI would be too long. I've included an example that's configured to talk to a publically-availble websocket server.

##Included Files

• send_to_websocket.sh - This will open up a connection and send its CLI argument to the server defined in the script.
  • usage: ./send_to_websocket.sh "MY AWESOME MESSAGE"
• websocket_echo_example.sh - This is an interactive script that will open a connection to the WebSocket.org Echo Server and will send any user input to it. It displays the server responses. The responses have have some leading special characters that are the header frame bytes that I didn't bother to remove.
  • usage: ./websocket_echo_example.sh

##TODO

• Send longer messages. Websocket framing is tricky in bash.
• Prettify the interactive script.
