I want to download a file from a server, but before doing so I would like to know the actual file size. I know that wget will display the filesize when the download is started, but this actually starts the download process also.

How can I just know the filesize of a remote file on an http server?

You can try typing:

wget --spider

It gives for example 134K:

$ wget --spider "" Spider mode enabled. Check if remote file exists. --2019-09-27 20:34:46-- Resolving askubuntu.com (askubuntu.com)... 151.101.193.69, 151.101.129.69, 151.101.65.69, ...
