Problem Statement: Understanding unix kernel ...user interface ...viz. the 'shell'

               PERL is bundled with most unix operating systems
               ....to know more about its origins ....purpose ...refer...man
               ...bundled with unix.

Opportunity : contrary to the tradional purposes exploit its as  shell
              ....The interface to unix.


              viz. exploit the use of a process pipe in perl ,
                   write or pack-age a perl re-usabe routine that can be
                   used with the command line option 'perl -e'
                   ...for more information ...may refer to a Quality Assurance
                   script written at veritas software india pvt ltd.


             ....Also PERL as such comes with all the basic features 
                 required to interface with kernel and programming interfaces
                 ...say much on the lines of 'perl -d' debugger option.


Objective:  package PERL as a shell to the unix.


Note: The above problem statement having been encountered in various scenarios
      and detailed in various 'Proof of concepts' as mentioned in 
      'http://uk.geocities.com/ravivenkatus/projects.pdf' ....apply appropriate
      'use-case' modeling, rationalize and arrive at a workable and feasible 
       solution both commercially and techinically viable.
