Are these :11496059224; numbers unique identifiers? Or can there be two or more lines with the same number? If they're unique identifiers, I think you could try with this thing.

First of all, if status.txt is too big, let's split it in many "tiny" files:

Code:
split -l 100000 status.txt tinyfile

Then, here we go:

Code:
IFS=";:"
declare -a status
for file in tinyfile*; do
  while read -r x y z; do
     status[$y]=$z
     done < $file
  while read a b c d e f g h i l; do
     h=${status[$d]}
     [[ $h = "" ]] || printf '%s;%s;%s:%s;%s;%s;%s;%s;%s;%s\n' "$a" "$b" "$c" "$d" "$e" "$f" "$g" "$h" "$i" "$l"
     done  < input.txt >> output.txt
  unset status
  done

I haven't tried it, so I don't know how fast or slow it can be.

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 send command n times EXAMPLES

/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"). SEE ALSO
The documentation for lirc is maintained as html pages. They are located under html/ in the documentation directory. lircd(8), mode2(1), smode2(1), xmode2(1), irrecord(1), irw(1), http://www.lirc.org. irsend 0.9.0-pre1 October 2010 IRSEND(1)
