Re: [Bug-wget] Does `wget -q -O /dev/null -S -o- url` ignore response body?

[Peng Yu]

curl has the --head option. Is there a reason why wget doesn't have it?

       -I, --head
              (HTTP  FTP  FILE)  Fetch the headers only! HTTP-servers
feature the command HEAD which this uses to get nothing but the header
of a document. When used on an
              FTP or FILE file, curl displays the file size and last
modification time only.
