This is, again, a useless use of cat, inefficient and occasionally dangerous.
I don't think your xargs version is going to work, since it will take multiple arguments beyond the first one to be filenames. If your system supports xargs -n, the -n 1 parameter would fix that.

CGI ::Application::Plugin::Authentication::Driver::GeneriUsermContributed Perl DocumeCGI::Application::Plugin::Authentication::Driver::Generic(3pm)NAME
CGI::Application::Plugin::Authentication::Driver::Generic - Generic Authentication driver
VERSION
This document describes CGI::Application::Plugin::Authentication::Driver::Generic version 0.20
SYNOPSIS
use base qw(CGI::Application);
use CGI::Application::Plugin::Authentication;
__PACKAGE__->authen->config(
DRIVER => [ 'Generic', { user1 => '123', user2 => '123' } ],
);
DESCRIPTION
This Driver offers a simple way to provide a user database to the CGI::Application::Plugin::Authentication plugin. It offers three ways to
provide a list of users to the plugin by providing a hash of username/password pairs, an array of arrays containing the username and
password pairs, or a code reference that returns back the username, or undef on success or failure.
EXAMPLE
my %users = (
user1 => '123',
user2 => '123',
);
__PACKAGE__->authen->config(
DRIVER => [ 'Generic', \%users ],
);
- or -
my @users = (
['example.com', 'user1', '123'],
['example.com', 'user2', '123'],
['foobar.com', 'user1', '123'],
);
__PACKAGE__->authen->config(
DRIVER => [ 'Generic', @users ],
CREDENTIALS => [ 'authen_domain', 'authen_username', 'authen_password' ]
);
- or -
sub check_password {
my @credentials = @_;
if ($credentials[0] eq 'test' && $credentials[1] eq 'secret') {
return 'testuser';
}
return;
}
__PACKAGE__->authen->config(
DRIVER => [ 'Generic', &check_password ],
);
METHODS
verify_credentials
This method will test the provided credentials against either the hash ref, array ref or code ref that the driver was configured with.
