I aligned your post to suit my requirement and works great. As always, awesome and thank you RudiC.
I have a small question here. My script uses 2 input files is facing issues when reading the second file as
Code:
awk -F "@" ' NR==FNR { ....; next; } {  #second file processing }' file1.txt file2.txt

It doesn't even read the 2nd file; Tested with some print statements in the 2nd file processing and they never get printed. When I changed it to if (NR!=FNR) the same part works great.
Code:
awk -F "@" ' { if(NR==FNR) {
....; next; }
if(NR!=FNR){
#second file processing } }' file1.txt file2.txt

and this works; I am not complaining about awk; I am sure that I messed up some where and not able to figure it out. But if(NR!=FNR) comes to my rescue at this point and hence I am using it.

Though I know it is not possible to figure out the issue without looking into the script and files, looking for some guess; did someone ever face similar issue.
!T[$1 OFS $2 OFS $3]++ should have worked in my script. But strangely, it didn't. So, I just tweaked as
Code:
if (!T[$1 OFS $2 OFS $3] {
v_array[$1 OFS $2]=(v_array[$1 OFS $2]? v_array[$1 OFS $2] "," $3 : $3)
T[$1 OFS $2 OFS $3="1"
}

and this works. I am not sure what difference does ++ and the if make as they should be ideal.

Thank you for your time.

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
