How do i split a variable of numbers with spaces... for example
echo "100 100 100 100" > temp.txt
as the values can always change in temp.txt, i think it will be feasible to split the numbers in accordance to column.

I have two files
1.txt
34, ABC, 7, 8, 0.9
35, CDE, 6.5, -2, 0.01
2.txt
34, ABC, 9, 6, -1.9
35, CDE, 8.5, -2.3, 5.01
So in both files common columns are 1 and 2
so final o/p should look like
34, ABC, 7, 8, 0.9, 9, 6, -1.9
35, CDE, 6.5, -2, 0.01, 8.5, -2.3, 5.01

App::Cmd::Tester::CaptureExternal(3pm) User Contributed Perl Documentation App::Cmd::Tester::CaptureExternal(3pm)
NAME
App::Cmd::Tester::CaptureExternal - Extends App::Cmd::Tester to capture from external subprograms
VERSION
version 0.318
SYNOPSIS
use Test::More tests => 4;
use App::Cmd::Tester::CaptureExternal;
use YourApp;
my $result = test_app(YourApp => [ qw(command --opt value) ]);
like($result->stdout, qr/expected output/, 'printed what we expected');
is($result->stderr, '', 'nothing sent to sderr');
ok($result->output, "STDOUT concatenated with STDERR");
DESCRIPTION
App::Cmd::Tester provides a useful scaffold for testing applications, but it is unable to capture output generated from any external
subprograms that are invoked from the application.
This subclass uses an alternate mechanism for capturing output (Capture::Tiny) that does capture from external programs, with one major
limitation.
It is not possible to capture externally from both STDOUT and STDERR while also having appropriately interleaved combined output.
Therefore, the "output" from this subclass simply concatenates the two.
You can still use "output" for testing if there is any output at all or for testing if something appeared in either output stream, but you
can't rely on the ordering being correct between lines to STDOUT and lines to STDERR.
