No, you can only get wget to compare a file of the same name between your local system and the remote server. > The only option I have come up with is to keep a copy of the "gz" file > in the temporary directory and run wget from there. You will need to keep the original "gz" file with a timestamp matching the server in order for wget to know that the file you have is the same as the one on the server. > Unfortunately, at least as far as I can tell, wget does not issue an > exit code if it has downloaded a newer file.

Keep one directory that matches the server and another one (or perhaps two) where you process new files. Before and after wget runs, you can check the dates on the directory that matches the server. You only need to process files that changed. Hope that helps. Tony
