      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);
