Dear sea,
I am not referring to tar command. I refer to compress command.
For example, I have a file name "aaaa" and I would like to compress it. I will run command "compress aaaa" and it will become aaaa.Z
After that I received another aaaa file again. This time when I perform compress aaaa, the system will prompt me a message as

Do you wish to write over the existing file aaaa.Z?

I have to enter "y" to overwrite the original file.

I would like to know how can I skip the answering "y" in my script so that the above prompt will not appear?

cpanplus::shell

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

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

	   $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.
