I am trying to get some lines from a file i did it with while-do-loop. since the files are huge it is taking much time. now i want to make it faster.
The requirement is the file will be having 1 million lines.
The format is like below.
What i know from the file is transnum in a set. I want to copy the ##transaction to till the next EOT for the particular transnum.
Also my requirement is from that file i want to copy only one set because my process will know only one transnum only.
So my output file will have only 10 to 15 lines (Only 1 transaction)
So please help me thanks.

wx::perl::datawalker
Wx::Perl::DataWalker(3pm) User Contributed Perl Documentation Wx::Perl::DataWalker(3pm)NAME
Wx::Perl::DataWalker - Perl extension for blah blah blah
SYNOPSIS
# alternatively, see the dataWalker.pl script in this distribution!
use Wx::Perl::DataWalker;
my $data_to_browse = {
# complex data structure.
# Good test: \%::
};
package MyWalkerDialog;
our @ISA = qw(Wx::App);
sub OnInit {
my $self = shift;
my $frame = Wx::Perl::DataWalker->new(
{data => $data_to_browse},
undef, -1,
"dataWalker",
);
$self->SetTopWindow($frame);
$frame->Show(1);
$frame->SetSize(500,500);
return 1;
}
package main;
my $app = MyWalkerDialog->new();
$app->MainLoop();
DESCRIPTION
"Wx::Perl::DataWalker" implements a "Wx::Frame" subclass that shows a relatively simple Perl data structure browser. After opening such a
frame and supplying it with a reference to an essentially arbitrary data structure, you can visually browse it by double-clicking
references.
So far, there is no tree view but only a display of the current level of the data structure. You can traverse back up the structure with a
back button.
Optionally, "Wx::Perl::DataWalker" displays the (approximate!) size of the data structure using "Devel::Size".
