🌸 NAME 🌸

okay so anyevent-mqtt-sub is a Perl script for subscribing to an MQTT topic. You’re reading the ANYEVEN...-MONITOR(1) page, from the User Contributed Perl Documentation collection. Hiiii bestie, let’s get into it. 💖

🌈 VERSION 🌈

It’s giving version 1.212810. Periodt.

✨ SYNOPSIS ✨

Run it like this:

anyevent-mqtt-sub [options] topic1 [topic2] [topic3] ...

🦋 DESCRIPTION 🦋

This script subscribes to one or more MQTT topics and prints any messages that it receives to stdout. That’s the whole vibe: you give it topic(s), it listens, messages show up in your terminal. Slay.

💅 OPTIONS 💅

  • -help — prints a brief help message. Tiny helper energy. 🫶
  • -man — prints the manual page. Yes, the very page you’re reading, meta king.
  • -host A.B.C.D — the host running the MQTT service. Default is 127.0.0.1.
  • -port NNNNN — the port of the running MQTT service. Default is 1883.
  • -qos N — the QoS level for the published message. Default is 0 ("MQTT_QOS_AT_MOST_ONCE").
  • -verbose — include more verbose output. More words, more lore. ✨
  • -keepalive NNN — the keep alive timer value. Defaults to 120 seconds. For simplicity, it is also currently used as the connection/subscription timeout. iykyk.
  • --history-size NNN — number of messages to keep for each topic. Defaults to keeping 20 messages.
  • --no-retain — ignore retained messages. That is, wait for new messages rather than processing existing retained messages. Fresh-message-only mindset. 🧚
