help with perl

Hi guys, I've loaded a file, and have removed the \n using chomp. however, when I try using length($file), it counts the whitespaces along with the characters. How do I just count the characters, anything but the whitespaces?
thanks

$str = "place the string you want to count in here";
$count = $str =~ s/([a-z])/$1/gi;
print $count;

Hi, that will just count the lowercase characters right? what about capital letters? would it be something along the lines as [a-z]||[A-Z]? also, what is the $1 for?
done it thanks for your help :)
