$cnt = @{[$str =~ /(\.)/g]};

This does not work for me. I expect the length of the string 'abc' to be 3, but your code returns 0:

use strict;
use warnings;

my $str = 'abc';
my $cnt = @{[$str =~ /(\.)/g]};
print "$cnt\n";

__END__
0

Remove the backslash, add the "s" modifier. And the parens aren't necessary.

my $cnt = @{[$str =~ /./sg]};

Cheaper alternative:

my $cnt =()= $str =~ /./sg;

Use the length() function.

hi all, counting number of characters is so easy.. use:length($stringname); $x=length($stringname);
