Help with a renaming script using Perl

I'm having trouble writing a script that will rename files in a directory based on a substitution.

For example, I have this and it works fine in terms of appending something to a filename:

use strict;
use warnings;
use File::Copy;


our @files = glob("*total*");      
foreach my $file(@files) {

my $newfile = $file . ".dat";

rename($file, $newfile)
   or die("Can't rename: $!\n");


}

So it will turn total.txt into total.txt.dat

However, when I change the script to this:

 use strict;
use warnings;
use File::Copy;


our @files = glob("*baz*");      
foreach my $file(@files) {

my $newfile = $file =~ s/total/CompleteTotal/;

rename($file, $newfile)
   or die("Can't rename: $!\n");


}

All I do is end up deleting the total.txt file instead of renaming the file CompleteTotal.txt; any ideas on the problem?

# my $newfile = $file =~ s/total/CompleteTotal/;
(my $newfile = $file) =~ s/total/CompleteTotal/;
