in reply to Cannot seem to remove empty/blank lines

Just another solution: 
use strict;

open(LOG,"+</etc/spamdomains.txt") || die "Can't open spam file\n";
my @lines = grep {!/^$/} <FILE>;
close(LOG);
print @lines;

Re^2: Cannot seem to remove empty/blank lines

    PLEASE HELP!!!!!! I need to remove blank lines from the eml files I am creating using my script with net::pop3. Speciffically I would like to remove the blank line after the string "Content-Transfer-Encoding: 7bit" in the eml files. I will attach my script below. What it does is download mail, split it into .eml files with a random incremented number as the file name. However the format is messed up because of that space after that line. Thanks ##############################################
    use Net::POP3;
    # Constructors
    $pop = Net::POP3->new('', Timeout => 60);
    $i = int rand(10000000000000);
    if ($pop->login("", "") > 0) {
    my $msgnums = $pop->list; # hashref of msgnum => size
    foreach my $msgnum (keys %$msgnums) {
    open(MAILBOX, ">$i.eml")
    or die "Cannot open Mailbox file $timestamp$i.eml";
    print "Writing to $i.eml\n";
    $i++;
    my $msg = $pop->get($msgnum);
    print MAILBOX @$msg;
    # $pop->delete($msgnum);
    close(MAILBOX)
    or die "Cannot close mailbox";
    }
    }
    $pop->quit;<\code>
