I see. Well then, this is me, back pedaling. I have no doubt what you are saying is accurate. And from that I gather that Perl is running on top of the shell rather than independent of it. That I didn't realize.

It follows that 'system' in Perl is an alias for 'shell' then, to put it in simple terms. That being the case demonstrates a LOT of overhead that I wasn't aware of. Thanks for enlightening me.

So when writing scripts to manage local stuff, use the shell. I'm good with that.

I'm wondering now if the same is true for Python?

CPANPLUS::Shell(3pm)					 Perl Programmers Reference Guide				      CPANPLUS::Shell(3pm)

NAME

       CPANPLUS::Shell

SYNOPSIS

	   use CPANPLUS::Shell; 	    # load the shell indicated by your
					    # config -- defaults to
					    # CPANPLUS::Shell::Default

	   use CPANPLUS::Shell qw[Classic]  # load CPANPLUS::Shell::Classic;

	   my $ui      = CPANPLUS::Shell->new();
	   my $name    = $ui->which;	    # Find out what shell you loaded

	   $ui->shell;			    # run the ui shell

DESCRIPTION

       This module is the generic loading (and base class) for all "CPANPLUS" shells. Through this module you can load any installed "CPANPLUS"
       shell.

       Just about all the functionality is provided by the shell that you have loaded, and not by this class (which merely functions as a generic
       loading class), so please consult the documentation of your shell of choice.
