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? 😜

Dropbox Community ModeratorAs 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.
I mean I upload a file and share it .
I will get a share link and I can download it with wget .
And I hard code the link to my program.
Someday, I delete the file on dropbox and forget to change the program share link code
So I want to add some code to check whether the link invalid or not
