I think Eric is really asking - if you have a directory (which may be empty or may contain files, subdirectories, etc), how do you tell if that directory is empty or not?
He states in his first message that he wants to know this because tar fails if you try to tar an empty directory. You could set it to not fail on errors, but then you would ignore all errors - and if something else created an error when tarring, you might not want to ignore it. Better to check first to see if the directory is empty, and only tar if it isn't. Is there a way to tell if a fileset is empty? If so, he could just create a fileset based on that dir and check it. I haven't found such a task if there is one.
