SWEET!!!!!! :-) Thanks, anyways.

Is there any reason you chose not to do it this way:
# From Perl Cookbook:
open(TRY,"+< try.txt") or die "Couldn't open try.txt: $!\n";
my @lines = <TRY> # Slurp all lines into an
array.
foreach my $line (@lines) { # Iterate through lines here.
$line =~ s/windows/linux/g; # Modify lines here.
}
seek(TRY,0,0) or die "Error seeking file:
$!\n";
print TRY @lines or die "Error writing to file:
$!\n";
truncate(TRY,tell(TRY)) or die "Error truncating file: $!\n";
close(TRY) or die "Error closing
file: $!\n";
It may not be as short and sweet, but it works, and it is easier to debug.

Freedom is an all-or-nothing proposition: either we
are completely free, or we are subjects of a
tyrannical system. If we lose one freedom in a
thousand, we become completely subjugated.
