Creating output file using Perl
As an simple example, I have the following files

fin1.zv being a one column set of number

Code:
1 90
2 80
3 60
4 30
5 20

fin2.zv is another file like this

Code:
1 10 20 30 40 50
2 60 70 80 90 0
3 90 80 70 60 50
4 40 30 20 10 0
5 10 20 30 40 50

Want to do $i - $2 / $2, let's say we store it in var[i]

var = $i - $2 / $2

where $2 is second column from the first file and $i is the ith column from the second file with i = 2 to i = NF

Want to output a file called file2.zp like this

$1 var[2] var[3] var[4] var[5] ...

where $1 is from file fin2.zv


I have a perl code which does this when I don't have the first column in the files.

Code:
    perl -e ' open(F1,"<$1"); open(F2,"<$2");  \
      while( ($p1=<F1>) && ($p2=<F2>) ) {      \
        foreach (split(/\s+/,$p2)) {           \
          print ($_ - $p1) / $p1," ";          \
        }                                      \
        print "\n"                             \
      }                                        \
      close(F1); close(F2); '                  \
      < fin1.zv fin2.zv                  \
      > fin2.zp

So I need to change it so that it takes account that the files now contain the additional first column as described and output the correct format I mentioned.

irsend

IRSEND(1)								FSF								 IRSEND(1)

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

	  irsend LIST DenonTuner ""
	  irsend SEND_ONCE  DenonTuner PROG-SCAN
	  irsend SEND_ONCE  OnkyoAmpli VOL-UP VOL-UP VOL-UP VOL-UP
	  irsend SEND_START OnkyoAmpli VOL-DOWN ; sleep 3
	  irsend SEND_STOP  OnkyoAmpli VOL-DOWN
	  irsend SET_TRANSMITTERS 1
	  irsend SET_TRANSMITTERS 1 3 4
	  irsend SIMULATE "0000000000000476 00 OK TECHNISAT_ST3004S"

FILES

       /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.
