I have a file that has a large chunk of identical text occuring multiple times, and I'd like to remove it. I've written the following, which I think would work if not for the fact that it sucks up 1.2GB of RAM in about 6 minutes and then crashes (winXP)

#!/usr/bin/perl

use strict;

my $a;
my $content;

open E, "<C:/auburn_courses_replace.txt" or die "Unable to open file $
+!";

undef $/;

$a = <E>;

$/ = "\n";

close E;
open F, "<C:/auburn_courses.txt" or die "Unable to open file $!";
undef $/;

$content = <F>;

$/ = "\n";

close F;

open G, ">>C:/auburn_courses2.txt" or die "Unable to open file $!";

#print $content;
#print $a;

$content =~ s/$a//g;

print G $content;


close G;

Anyone know how to do what I'm trying to do and succeed? :)

Update! All fixed, ignore me
