Re: out of memory error while reading file contents into an array

You should iterate over the filehandle directly.

use strict;
use warnings;

my $filename = 'filename.txt';

open(my $fh, $filename) or die "cann't open file filename : $!\n";

while (<$fh>) {

   my $line = $_;

   next if ($line =~ /^\s*$/); # skip blank lines
   chomp($line);               # remove line endings
   
   # .... do your coding here on each line

}

close($fh);
