This is a bit overkill for just renaming files in a directory, but if you want to rename files in a directory and all subdirectories (or rename directories also), you can modify the first two lines of the sub:
use File::Find;
my @dirs = qw(.);

find( sub{
 return if $File::Find::name eq $File::Find::topdir;
 $File::Find::prune=1, return if -d;
 if ((my $newname = $_) =~ tr/ /./) {
  print "Renaming $File::Find::name to $newname\n";
  rename $_, $newname or die "Can't rename $_: $!";
 }
}, @dirs);
