Hi,

I want to create a script that checks an URL and perform an action (download + unzip) when the "Last-Modified" header of the remote file changed. I thought about fetching the header with curl but then I have to store it somewhere for each file and perform a date comparison.

Does anyone have a different idea using (mostly) standard unix tools?

thanks
