My point is they're not the same.

`ls` means "run the ls command, and split apart its output on all whitespace". You can get away with this when your filenames have no spaces in them, but if they do, that's a problem.

* means 'generate a list of all files in the current folder'. It's not part of ls, it's part of the shell, meaning it works nearly everywhere. Type echo * into your shell and see what it does.

You can use it in more complicated ways. A* would be 'all files beginning with an uppercase letter A', *.txt would be "all files ending in the extension .txt", and so forth. You can even do things like /path/to/*/file, to find a file named 'file' inside any folder inside /path/to/.

It won't split on spaces, only on filenames.

NAME

       CPANPLUS::Shell - base class for CPANPLUS shells

SYNOPSIS

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

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.
