I have a txt file with this info where the delimeter is ";" 
san francisco; oakland; new york city; boston;
miami; detroit;

I want to count how many cities are listed so the above would have 6 as the count. My attempt below gives me a count of 1. Please advise how I can do it correctly?? 
my $filename = 'myname.txt';
my $ct = 0;

open FILE, $filename || "$!";

while(<FILE>)
{
    chomp;
    my @arr = split /;/, $_;
    $ct++
   
}
print $ct;
close FILE;
