You might see that the Dropbox Community team have been busy working on some major updates to the Community itself! So, here is some info on what’s changed, what’s staying the same and what you can expect from the Dropbox Community overall.

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? 😜

Hi alicera, thanks for messaging the Community.
Could you clarify what you're trying to do?
There isn't a direct method to test if a shared link to a file exists or not, since it would still generate a message on the Dropbox site, saying there isn't a file there.
This will help me to assist further!
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?

As far as I'm aware, it isn't possible to determine if a file exists at a specific link. Entering the incorrect link means it wouldn't be possible to locate the file.
If the file was deleted, the shared link would also be deleted, and can't be restored to the same link.

Thanks for your help.
Does it has the code for python with dropbox lib
alicera, The questions you place here (including the last one) have their answers in other thread you asking for the same! Greg' proposal there is posted long before your last question. It's the same for all Dropbox supported SDKs (not just Python). There you can see too why/how my proposal works. 😉
