Continue downloading files starting from the URL where it stops: WGET

Question

I want to download files using wget. The maximum depth is up to 3. Now, I know that there is a big possibility that the files in the URL will be updated. Is there a way that these updated/modified files will be the only ones to be downloaded?

For example, day 1: I'll run the Python script that will download all files from a particular site.

Day 2: I'll run the same script, expecting that it will download all UPDATED files ONLY.

What parameter do I need to add to do this?

Answer 1

You can use the -N (--timestamping) option. For example, wget -N www.google.com.
