Andrek, I put in your code and it executed to work great! I went one step further and added the following piece to list out any existing directories and it's corresponding files:

if [ -d ${lsarry[$start]} ]
then
echo "-${lsarry[$start]}- is a directory"
cd ${lsarry[$start]}
ls -l
else

I do have one more question however. As someone always learning in the Unix Scripting field, I was wondering if you could explain what a few of the expressions are doing?

lslist="`ls -m | tr -d \",\"`"
set -A lsarry $lslist
start=1
while [ $start -lt ${#lsarry[*]} ] This is where I get confused. I understand that you are asking if the index is less than the value in the array, but what does the # before the lsarry mean? I take it that the[*] means the last array slot to contain a value?
do
if [ -d ${lsarry[$start]} ] I'm unfamiliar with -d before the array. Does this mean "IF 'D' = ArrayValue?" How is the code being interpreted?
then
echo "-${lsarry[$start]}- is a directory"
cd ${lsarry[$start]}
ls -l
else
echo "-${lsarry[$start]}- is not a directory"
fi
start=`expr $start + 1`
done

Everything after the first two questions in italics I understand, if you could explain those two just a little bit more, it would be greatly appreciated. Thanks!

NAME

       CPANPLUS::Shell - base class for CPANPLUS shells

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

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.
