This is just a simple utility program. It doesn't do much. Specifically, all the QoS features are unsupported. Also, don't expect fancy error messages and such :-)

-h --host

MQTT server to connect to, required.

-p --publish topic

Publish a message. Uses the message given with -m, or will read lines from stdin, and publish a message for each given line.

-m --message message

Message to publish. Requires -p.

-r --retain

Causes messages published with -p to have the "retain" flag on.

-s --subscribe filter

Subscribe to the given topic filter. Use the standard MQTT wildcards like + and #. Outputs matching published messages on stdout. Can be given multiple times.

-e --except filter

Suppress published messages that match filter. Can be given multiple times.

--count number

Quit after receiving number messages.

--message-only

Output only the message values, without the topics.

-1 --one

Shortcut for --count 1 --message-only.

--color

--no-color

For each given -s, print the matching topic in a different color. Note that the first matching topic will be used for color selection, so specify the topics with the most specific one first, the least specific one (like #) last.

Color is enabled by default if stdout is a terminal.

--raw

Pass ASCII control characters unaltered. By default, they're replaced by ^@ notation or, when --color is enabled, reverse video characters. For example, an ASCII newline would be displayed as ^J unless --raw is used.

-d --datetime format

Prefix messages with a timestamp. Optionally, a format for strftime can be supplied.

-u --user --username username

Specify a username. Overrides the environment variable MQTT_SIMPLE_USERNAME.

--pass --password password

Specify a password. Overrides the environment variable MQTT_SIMPLE_PASSWORD.
