use strict;
use warnings;
    while (my $row = <>) {
      chomp $row;
      print "$row\n";
    }

but nothing happens!. what is my mistake??? Or can you suggest similar (and fast) solution?

Iam not super familiar with perl but have worked with it alittle in the past.I'm guessing there is an issue with your loop, but like I stated i'm not a perl monk! Here is a program I used to read from a file and prints it:

#!/usr/bin/perl

use strict;
use warnings;

#Opens a file handler
open my $fh, '<', '/home/user/Desktop/ScriptForChangesets/ToBeRead.txt' or die "Can't open file";

#Prints the file contents
print do{local $/; <$fh>};

Hope this helps!
