Hm... 🤔 alicera, let's change it little bit:
if wget -q --method=HEAD --max-redirect 0 https://www.dropbox.com/s/abcdefg/123?dl=0 ; then echo "This page does not exist." else echo "This page exists." fi
Is it working now? 😜
Assume these link are setting to share
correct drop box link: https://www.dropbox.com/s/abcdefg/123?dl=0
incorrect drop box link: https://www.dropbox.com/s/abcdefghiklnd/123?dl=0
where the incorrect drop box link is the two status to generate
1. mistake by myself. I got the link wrong when typing.
2. I remove the file but link is hard code somewhere
So I wnat to write a code to check whether the link work or not
Do you know what I mean?

The problem you're likely running into is that even when the file doesn't exist, the page still does, and that is what wget is checking for. You're not actually checking for the existence of a file; you're checking a specific page (the URL of the shared link), and that page will load even when the file doesn't exist, so wget reports that the page exists.

It can download a file (invalid file)
