IRRECORD(1) User Commands IRRECORD(1)NAME
irrecord - application for recording IR-codes for usage with LIRC
SYNOPSIS
irrecord [options] file
DESCRIPTION
This program will record the signals from your remote control and create a config file for lircd. A proper config file for lircd is maybe
the most vital part of this package, so you should invest some time to create a working config file. Although I put a good deal of effort
in this program it is often not possible to automatically recognize all features of a remote control.
If the program fails to recognize the protocol of the remote control you should use the --force option to at least create a config file in
raw mode.
If file already exists and contains a valid config irrecord will use the protocol description found there and will only try to record the
buttons. This is very useful if you want to learn a remote where config files of the same brand are already available. Of course this will
only work if the remotes use the same protocol but it's worth a try. You will find template files for the most common protocols in the
remotes/generic/ directory of this package. The name of the new file is created by appending .conf to the given filename in this case.

lircd - LIRC daemon decodes infrared signals and provides them on a Unix domain socket.
SYNOPSIS
lircd [options] [config-file]
DESCRIPTION
The main task of lircd is to decode the infrared signals and provide an uniform interface for client applications. Clients can connect to
lircd through a Unix domain socket which is located in var/run/lirc/lircd. Using this socket they will get the infrared codes received by
lircd and they can send commands to lircd.

OPTIONS
The --permission option gives the file permission of var/run/lirc/lircd if it has to be created in octal representation. Read the documen-
tation for chmod for further details. If no --permission option is given when the socket is initially created the default is to give all
users read and write permissions (0666 in octal representation). If /var/run/lirc/lircd already exists this option has no effect.
With the --device option you can select the character device which lircd should read from. The default currently is /dev/lirc but it proba-
bly will change in future.
If you're using the dev/input driver, you can use name=STRING or phys=STRING to select the device; lircd will look in /dev/input to find a
device with a matching description. This is useful in case the device name isn't fixed. STRING may contain the '*' and '?' wildcards and
'' to mark them as literal.
With the --listen option you can let lircd listen for network connections on the given address/port. The default address is 0.0.0.0, which
means that connections on all network interfaces will be accepted. The default port is 8765. No security checks are currently implemented.
The listening lircd instance will send all IR events to the connecting lircd instances.
The --connect option allows you to connect to other lircd servers that provide a network socket at the given host and port number. The num-
ber of such connections is currently limited to 100. The connecting lircd instance will receive IR events from the lircd instance it con-
nects to.
With the --output option you can select Unix domain socket, which lircd will write remote key codes to. The default currently is
var/run/lirc/lircd.
With the --pidfile option you can select the lircd daemon pid file. The default currently is /var/run/lirc/lircd.pid.
With the --logfile option you can select the lircd daemon log file. The default currently is /var/log/lircd. Note that this option will
only be available if you compiled lircd without syslog support.
The --release option enables automatic generation of release events for each button press. lircd will append the given suffix to the button
name for each release event. If no suffix is given the default suffix is '_UP'.
The --allow-simulate option will enable the SIMULATE command which can be issued using irsend(1). This will allow simulating arbitrary IR
events from the command line. Use this option with caution because it will give all users with access to the lircd socket wide control over
you system. E.g. if you have configured your system to shut down by a button press on your remote control, everybody will be able to shut
down your system from the command line.
On Linux systems the --uinput option will enable automatic generation of Linux input events. lircd will open /dev/input/uinput and inject
key events to the Linux kernel. The key code depends on the name that was given a button in the lircd config file, e.g. if the button is
named KEY_1, the '1' key code will be generated. You will find a complete list of possible button names in /usr/include/linux/input.h.
The --repeat-max option sets an upper limit to the number of repeats when sending a signal. The current default is 600. A SEND_START
request will repeat the signal this many times. Also, if the number of repeats in a SEND_ONCE request exceeds this number, it will be
replaced by this number.
FILES
The config file for lircd is located in /etc/lirc/lircd.conf. lircd has its own log file in /var/log/lircd (beginning with LIRC version
0.6.1 you can configure lircd to use syslogd for log messages; then it depends on your system configuration where log messages will show
up). You can make lircd reread its config file and reopen its log file by sending the HUP signal to the program. That way you can rotate
old log files.
DAEMONS
lircd and lircmd are daemons. You should start them in some init script depending on your system. There are some example scripts for dif-
ferent distributions in the contrib directory. lircmd has to be started after lircd as it connects to the socket lircd provides.
If you start lircd or lircmd from your shell prompt you will usually get back immediately to the prompt. Often people think that the pro-
gram has died. But this is not an error. lircd and lircmd are daemons. Daemons always run in background.
