Simplified, to do this in shell
Notice how piping the commands together I easily applied the desired result to "z".
Lets go one step further, if I wanted a specific field, again simplified
Here Id isolate the version and put in in "z"
Im sure a perl wizard would be able to do this in about as many characters as I used in shell. This is what Im after. My question is not so much related to how to execute this particular function, but how to learn how to nest/pipe commands together.

What is the perl equivalent to grep -c
-c, --count
Suppress normal output; instead print a count of match-
ing lines for each input file. With the -v, --invert-
match option (see below), count non-matching lines.

class::factory::util
Class::Factory::Util(3) User Contributed Perl Documentation Class::Factory::Util(3)NAME
Class::Factory::Util - Provide utility methods for factory classes
SYNOPSIS
package My::Class;
use Class::Factory::Util;
My::Class->subclasses;
DESCRIPTION
This module exports a method that is useful for factory classes.
USAGE
When this module is loaded, it creates a method in its caller named "subclasses()". This method returns a list of the available subclasses
for the package. It does this by looking in @INC as well as the directory containing the caller, and finding any modules in the immediate
subdirectories of the calling module.
So if you have the modules "Foo::Base", "Foo::Base::Bar", and "Foo::Base::Baz", then the return value of "Foo::Base->subclasses()" would be
"Bar" and "Baz".
