Question regarding Command pattern

Question

Hi!
I have a question regarding the Command pattern:
//Invoker as defined in GOF Design Patterns
public class SomeServer {
    //Receiver as defined in GOF Design Patterns.
    private Receiver receiver;
    //Request from a network client.
    public void service(SomeRequest request) {
        Command cmd = CommandFactory.createCommand(request);
        cmd.execute();
}The concrete command which implements the Command needs a reference to Receiver in order to execute it's operation but how is the concrete command best configured? Should I send Receiver along with the request
as a parameter to the createCommand method or should i configure the receiver inside the CommandFactory or
send it as a paramter to the execute method? Since SomeServer acts as both client and invoker, SomeServer "knows" about the Commands receiver. Is this a bad
thing?
Regards

Answer 1

#!/bin/bash
DATE=$(date '+%y-%m-%d')
if find | grep -q $DATE ; then
echo "OK - Backup files found"
exit 0
else
echo "Critical - No Backups found today!"
exit 2
fi
should work too and it's a bit shorter.
