I can't follow where Host/Device IP is cooming from. I guess this shows that you want to merge two csv files?

I never worked on Solaris 10, but why not looking for .tar.gz and then using tar xzf (or something like that) to extract? A second way if installed would be cpan. get module, make module, test module, install module.

Anyway, if you're able to extract one column, you just have to add the same part again in your loop by checking for another column ... you're creating an array or append on a string all your results (formatted) for both csv-files then writing a third loop printing into csv-file.

Following code is not tested and should be more like a kind of Pseudo Code

my @aColumns1;
my @aColumns2;

open ( my $sData, '<', $hFile ) or die "Could not open '$hFile' $!\n";
while ( my $sLine = <$sData> ) 
{
  chomp $sLine;
  my @aFields = split "," , $sLine;
  push ( @aColumns1, $aField[1] );
  push ( @aColumns2, $aField[3] );
}
close ( $hFile );

my @aColumns3;
my @aColumns4;
@aFields = '';

open ( $sData, '<', $hFile ) or die "Could not open '$hFile' $!\n";
while ( $sLine = <$sData> ) 
{
  chomp $sLine;
  @aFields = split "," , $sLine;
  push ( @aColumns3, $aField[2] );
  push ( @aColumns4, $aField[4] );
}
close ( $hFile );

open ( '>', $hFile ) or die "Could not open '$hFile' $!\n";
for (...)
{
    print $hFile "$aColumns1[x];$aColumns2[x];$aColumns3[x];$aColumns4
+[x]\n";
}
close ( $hFile );

If you would like you could probably use 2D-Arrays too.

Yaerox, I think you'll find that the host IP is initially a script argument and is then subsequently returned by the invoked CISCO show command (IIRC :-).
A user level that continues to overstate my experience :-))

Yeah you're right. Found it ;-) But I think the way how to get this done can be pretty the same ... if not feel free to tell me :-)

Thank you Sir.

G'day bks,

Welcome to the monastery.

"I would be getting similar output from different devices and i would like append the output to same csv file"

I don't know which of the two CSV files this refers to. Use a mode of '>' to write to a new file; and a mode of '>>' to append to an existing file. See open for details. I've used append mode for both files in the code below.

"I tried installing text::csv_xs, but unfortunately i wasnt able extract *.tgz as it gave some checksum error. Please guide me or point me in right direction about how to install modules that are in *.tgz format"

You'll need to show us what you did and what output you got. The guidelines in "How do I post a question effectively?" explain the sort of information we need and how to present it.

"Please post some sample code to achieve my requirement that would really be of great help"

The code below shows how to use Text::CSV for all your I/O.

#!/usr/bin/env perl -l

use strict;
use warnings;
use autodie;

use Text::CSV;

my ($all_csv, $sel_csv) = qw{pm_1082609_all.csv pm_1082609_sel.csv};
my $ip = '192.168.10.3';
chomp( my @output = <DATA> );

my $csv = Text::CSV::->new();

open my $out_all_fh, '>>', $all_csv;
$csv->print($out_all_fh => [ split /\t/ ]) for @output;
close $out_all_fh;

open my $in_all_fh, '<', $all_csv;
open my $out_sel_fh, '>>', $sel_csv;

while (my $row = $csv->getline($in_all_fh)) {
    $csv->print($out_sel_fh, [ $ip, @$row[0,8] ]);
} 

close $in_all_fh;
close $out_sel_fh;

Here's the file contents after running that script.

$ cat pm_1082609_all.csv

Thanks a lot Ken. By using your sample script i was able to extract the required columns.
