Hi, I'm a beginner in perl and I made some code to clean log files. But the speed isn't fast enough. So I was wondering if a more advanced user could change it a little. Thx in advance 
#!/usr/bin/perl
use warnings;
use strict;
use Term::ReadKey;
print "[-] Enter the filename: ";
chomp($file = <STDIN>);
open(LIST,$file);
@file1 = <LIST>;
close(LIST);
if (-e "cleaned.txt") {
    print "[-] Can cleaned.txt be deleted? ";
    $answer = <stdin>;
    if ($answer =~ /yes/i) {
        unlink "cleaned.txt";
    }
    else {
        &exit
    }
}
print "[-] Cleaning...\n";
foreach $data (@file1) {
    ($w1) = split(/:/,$data);
    open(OUTPUT,">>cleaned.txt");
    print OUTPUT $w1."\n" unless ($data =~ /-/);
    close(OUTPUT);
}
&exit;
sub exit() {
    ReadMode 2;
  print "\n[-] Press ENTER to exit...";
  <STDIN>;
  exit;
}

edit: Sorry people. I just saw that I posted this in the wrong section. Can a mod please move this.
