How to include \r in this mqtt message when running command-line mqtt client?

Question

I am using a command-line mqtt client. https://github.com/shirou/mqttcli

I would like to publish a message with \r carriage return character inside. Below is what I did.

mqtt-cli mqtt.test.com topic "mqtt_msg 1\r"

However, the carriage return character is not sent. Instead, the ASCII "\r" characters are sent. How can I put the \r carriage return inside the mqtt message?

Answer 1

Try this.

mqtt-cli mqtt.test.com topic "mqtt_msg 1\\r"

You need to add the extra \ as escape character.
