> A simple MQTT version 3.1.1 client that will publish a single message on a topic and exit.
Publish a temperature value of 32 on the topic `sensors/temperature` to 192.168.1.1 (defaults to `localhost`) with Quality of Service (`QoS`) set to 1:
mosquitto_pub -h {192.168.1.1} -t {sensors/temperature} -m {32} -q {1}
Publish timestamp and temperature data on the topic `sensors/temperature` to a remote host on a non-standard port:
mosquitto_pub -h {192.168.1.1} -p {1885} -t {sensors/temperature} -m "{1266193804 32}"
Publish light switch status and retain the message on the topic `switches/kitchen_lights/status` to a remote host because there may be a long period of time between light switch events:
mosquitto_pub -r -h "{iot.eclipse.org}" -t {switches/kitchen_lights/status} -m "{on}"
Send the contents of a file (`data.txt`) as a message and publish it to `sensors/temperature` topic:
mosquitto_pub -t {sensors/temperature} -f {data.txt}
Send the contents of a file (`data.txt`), by reading from stdin and send the entire input as a message and publish it to `sensors/temperature` topic:
mosquitto_pub -t {sensors/temperature} -s < {data.txt}
Read newline delimited data from stdin as a message and publish it to `sensors/temperature` topic:
{echo data.txt} | mosquitto_pub -t {sensors/temperature} -l
