How to "nc" data to socket file?

  • 772

I have a server listening on a socket file /tmp/any.sock and I want to write something to that socket. If it would be listening on a port, I would use echo mymessage | nc localhost 1234, but nc /tmp/any.sock or echo mymessage > /tmp/any.sockdoes not work.

    You can use nc for it as well with the -U option.

    Example

    1. Open listening socket in one terminal

      nc -lU socket.sock

    2. Input of data on the other terminal:

      echo mytext | nc -U socket.sock

    3. Watch the mytext being printed on the first terminal. By default nc stops listening after an End-of-File character, but I assume your server can decide on its own.
