Here's is the another way.Treating the scalar as a file handle.
use strict;
use warnings;
use IO::Scalar;
my $string = "one\ntwo\nthree\nfour\nfive\nsix";
my $scalar_fh = IO::Scalar->new( \$string ); # creating a scalar fi
+le handle.
my $count = 0;
$count++ while (<$scalar_fh> );
print $count;
This is not efficient than using tr. But, you can process a string as file by this way.
