That sounds great, but the "file.txt" is a zero byte file, regardless of
whether the file is downloaded or not.
Perhaps wget does not allow redirection?

It does if you send the data to stdout:

wget -O - -N http://yoursite/file.html > file.txt

Or you can send it to /dev/null:

wget -O /dev/null -N http://yoursite/file.html

Or you can count the output:

wget -O - -N http://yoursite/file.html | wc

Etc..
