To scan a file you have to download it. You can only scan it on the server if it is your server and you have remote access to it. So if you want to download it from the terminal and run a scan as soon as it is downloaded, you should use a command like:
or if you don't need the file after download, you can pipe it to clamscan:

You can use curl to do this:
By default, curl will not save the file to your drive space.
