It does work, but you need to be somewhere else (not in the directory you use it from, since on its own their's no chance to give the link another name):

Hi All
Please excuse another straightforward question. When creating a tar archive from a directory I am attempting to use wildcards to eliminate certain filetypes (otherwise the archive gets too large). So I am looking for something along these lines.

These 2 websites do a GREAT job of explaining different types of wildcards. I learned about the categories of characters which I never knew about at all.

poe::component::connection::keepalive
POE::Component::Connection::Keepalive(3pm) User Contributed Perl Documentation POE::Component::Connection::Keepalive(3pm)NAME
POE::Component::Connection::Keepalive - a wheel wrapper around a kept-alive socket
VERSION
version 0.271
SYNOPSIS
See the SYNOPSIS for POE::Component::Client::Keepalive for a
complete working example.
my $connection = $response->{connection};
$heap->{connection} = $connection;
$connection->start( InputEvent => "got_input" );
delete $heap->{connection}; # When done with it.
DESCRIPTION
POE::Component::Connection::Keepalive is a helper class for POE::Component::Client::Keepalive. It wraps managed sockets, providing a few
extra features.
Connection objects free their underlying sockets when they are DESTROYed. This eliminates the need to explicitly free sockets when you are
done with them.
Connection objects manage POE::Wheel::ReadWrite objects internally, saving a bit of effort.
new
Creates a new POE::Component::Connection::Keepalive instance. It accepts two parameters: A socket handle (socket) and a reference to a
POE::Component::Client::Keepalive object to manage the socket when the connection is destroyed.
my $conn = POE::Component::Connection::Keepalive->new(
socket => $socket_handle,
manager => $poe_component_client_keepalive,
);
new() is usually called by a POE::Component::Client::Keepalive object.
start
Starts a POE::Wheel::ReadWrite object. All parameters except Handle for start() are passed directly to POE::Wheel::ReadWrite's
constructor. Handle is provided by the connection object. start() returns a reference to the new POE::Wheel::ReadWrite object, but it
is not necessary to save a copy of that wheel. The connection object keeps a copy of the reference internally, so the wheel will persist
as long as the connection does. The POE::Wheel::ReadWrite object will be DESTROYed when the connection object is.
# Asynchronous connection from Client::Keepalive.
sub handle_connection {
my $connection_info = $_[ARG0];
$_[HEAP]->{connection} = $connection_info->{connection};
$heap->{connection}->start(
InputEvent => "got_input",
ErrorEvent => "got_error",
);
}
# Stop the connection (and the wheel) when an error occurs.
sub handle_error {
delete $_[HEAP]->{connection};
}
wheel
Returns a reference to the internal POE::Wheel::ReadWrite object, so that methods may be called upon it.
$heap->{connection}->wheel()->pause_input();
close
Closes the connection immediately. Calls shutdown_input() and shutdown_output() on the wheel also.
