Perl Regular Expressions for Password Checking

OK... I admit it... I'm a "regular expression" ignoramus.  

I'm enforcing passwords of at least 6 characters in length, with at least 1 uppercase letter, 1 lowercase letter, and at least 1 number.  How do I construct a regular expression that checks that?

Just chain togethor a regexp for each condition you need
my $pwd = '12A45b';

if ( $pwd =~ /\w{6,}/ and $pwd =~ /\d/ and $pwd =~ /[A-Z]/ and $pwd =~ /[a-z]/ )
    # password is valid
    #re enter password
