Anything can fork(), not just init. X runs applications or a window manager when it starts and those applications fork().

irexec
IREXEC(1) User Commands IREXEC(1)
NAME
irexec - run programs with one button press
SYNOPSIS
irexec [options] [config_file]
DESCRIPTION
This program lets you execute arbitrary commands on an IR signal decoded by lircd, the LIRC daemon. You can give irexec a command line
parameter which has to be a name of a valid config file. If no command line parameters are given irexec reads the default config file which
is usually ~/.lircrc.
If irexec executes a program it will wait until this program terminates. So append a '&' to the command string if you don't want that.
The config string consists of the command to be run.
-h --help
display usage summary
-v --version
display version
-d --daemon
run in background
-n --name
use this program name
OPTIONS
If you add the --daemon option irexec will fork to background. That way you can easily start irexec from an init script. In this case you
should specify a config file on the command line as irexec won't be able to find your home directory. Potential uses are shutting down the
computer, starting a dial-up connection etc.
NOTE
If you start irexec, it reads your ~/.lircrc and reacts only on prog= entries that point to irexec. If you have included more than one pro-
gram in your .lircrc, then start all these programs, they react itself only to their according entries in .lircrc.
SEE ALSO
The documentation for lirc is maintained as html pages. They are located under html/ in the documentation directory.
