[Bug-wget] downloading a file from a web (updated every 24 hours)

[Mingfeng Lin]

Greetings!

I'm new to wget and haven't found the answer in the help file.  I want
to download a file from an URL, and this file is updated every 24
hours on the server.  What I would like to do is to add a -wget- bat
file in the startup menu of windows, and then, every time I start the
computer the -wget- should (1) check with the file on the server and
see if a copy has been downloaded; if not, download the file and keep
it.

The problem I have is that if I use a -timestamping- option, the file
will be always replaced/updated with the most recent one.  If I do not
use this option, then all versions will be saved - however if I
startup my computer more than once a day, there will be multiple
copies of the same file.  So I was curious if I missed any options in
-wget- that can help me with this?

Thank you very much for your help!
