@SriniShoo : One array is enough I think

Try

Code:
akshay@nio:/tmp$ cat infile
K00001 1 1 4 3 5
K00001 2 4 4 3 3
K00001 8 9 1 5 2
K00006 7 2 3 2 8
K00006 3 4 6 6 3
K00006 5 1 9 7 7
K00008 1 1 2 1 1
K00011 14 18 18 12 15

Code:
awk '
	function p(v, s)
	{
		for(i=2;i<=NF;i++)
		{
		  if(v == "push"){
			A[$1,i]+=$i
		  }
		  else{	
			if(($1,i) in  A)
			  s = (length(s) ? s OFS:"") A[$1,i]
			  delete A[$1,i]
		  }
		}
		return s
	}

 FNR==NR{ p("push"); next }

        { if(length(s=p()))print $1,s }

    ' infile infile

Resulting
Code:
K00001 11 14 9 11 10
K00006 15 7 18 15 18
K00008 1 1 2 1 1
K00011 14 18 18 12 15


OR

Code:
awk '{
	for(i=2; i<=NF; i++)
	A[$1,i]+=$i; 
	max = ( NF > max ) ? NF : max
     }
  END{
	for(i in A)
	{
	  if(i in A)
	  {
		split(i,X,SUBSEP)
		s = X[1]
		for(j=2; j<=max; j++)
		{
			if((X[1],j) in A)
			{
				s = s OFS A[X[1],j] 
				delete A[X[1],j]
			} 
		}
			
		print s
	  }
	}
     }'  infile


Resulting (if you don't care order)

Code:
K00008 1 1 2 1 1
K00006 15 7 18 15 18
K00001 11 14 9 11 10
K00011 14 18 18 12 15

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 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
