May I suggest something like this to read your lines of text: 

use feature ":5.14";
use warnings FATAL => qw(all);
use strict;
use Data::Dump qw(dump pp);

sub readFile($)
 {my ($f) = @_;
  $f or die "readFile: No file specified";
  open my $F, "<$f" or die "Cannot open $f for input";
  local $/ = undef;
  <$F> 
 }

print readFile("readFile.pm");

Produces:

use feature ":5.14";
use warnings FATAL => qw(all);
use strict;
use Data::Dump qw(dump pp);

sub readFile($)
 {my ($f) = @_;
  $f or die "readFile: No file specified";
  open my $F, "<$f" or die "Cannot open $f for input";
  local $/ = undef;
  <$F> 
 }

print readFile("readFile.pm");
