IRSEND(1) User Commands IRSEND(1)NAME
irsend - basic LIRC program to send infra-red commands
SYNOPSIS
irsend [options] DIRECTIVE REMOTE CODE [CODE...]
DESCRIPTION
Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such
as TV boxes, HiFi sets, etc.
DIRECTIVE can be:
SEND_ONCE - send CODE [CODE ...] once
SEND_START - start repeating CODE
SEND_STOP - stop repeating CODE
LIST - list configured remote items
SET_TRANSMITTERS - set transmitters NUM [NUM ...]
SIMULATE - simulate IR event
REMOTE is the name of a remote, as described in the lircd configuration file.
CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file.
NUM is the transmitter number of the hardware device.
For the LIST DIRECTIVE, REMOTE and/or CODE can be empty:
LIST "" "" - list all configured remote names
LIST REMOTE "" - list all codes of REMOTE
LIST REMOTE CODE - list only CODE of REMOTE
The SIMULATE command only works if it has been explicitly enabled in lircd.
-h --help
display usage summary
-v --version
display version
-d --device
use given lircd socket [/var/run/lirc/lircd]
-a --address=host[:port]
connect to lircd at this address
-# --count=n

EXAMPLES
irsend LIST DenonTuner ""
irsend SEND_ONCE DenonTuner PROG-SCAN
irsend SEND_ONCE OnkyoAmpli VOL-UP VOL-UP VOL-UP VOL-UP
irsend SEND_START OnkyoAmpli VOL-DOWN ; sleep 3
irsend SEND_STOP OnkyoAmpli VOL-DOWN
irsend SET_TRANSMITTERS 1
irsend SET_TRANSMITTERS 1 3 4
irsend SIMULATE "0000000000000476 00 OK TECHNISAT_ST3004S"
FILES
/etc/lirc/lircd.conf
Default lircd configuration file. It should contain all the remotes, their infra-red codes and the corresponding timing and wave-
form details.
DIAGNOSTICS
If lircd is not running (or /var/run/lirc/lircd lacks write permissions) irsend aborts with the following diagnostics:
"irsend: could not connect to socket"
"irsend: Connection refused" (or "Permission denied").
