Is there a way to send two separate messages?

[grappas]

I need to send 2 messages (which first is the password)
I've tried:
wscat -c ws://127.0.0.1:33074/rcon -x "$(printf "secret\ncommand")"
But string is treated as single command. In result pong is returned as bad password.
I've also tried:
wscat -c ws://127.0.0.1:33074/rcon -x $(printf "secret\ncommand")
But in result command is ignored.

wscat -c ws://127.0.0.1:33074/rcon -x $(printf "secret\n") -x $(printf "command\n")
Also returns bad password

It doesn't seem to support sending two message with -x.

Why not just open the connection without -x and then send two separate messages? Or just combine two messages into single message and separate them at server side.

Yes. I'm asking for support.

I want to put it into the script. Now you see.

I'm not an author/owner. Project (server) is non-free.
