How to rename the downloaded file with wget?
To download the SOFA Statistics from the server I use the wget command:
wget -c http://sourceforge.net/projects/sofastatistics/files/latest/download?source=dlp
The filename of downloaded file in this case is download?source=files. If I add the --output-document option to the command, to rename the output file to sofastatistics-latest.deb, the format of downloaded file is not recognized by dpkg package.
dpkg-deb: error: `sofastatistics-latest.deb' is not a debian format archive
How to rename correctly the downloaded file with wget?
UPDATE - Jan 08 '15
With the provided link the downloaded file always will be a *.tar.gz one. To get it with the real name just add the --content-disposition option as this (thanks to @6EQUJ5!):
wget --content-disposition http://sourceforge.net/projects/sofastatistics/files/latest/download?source=dlp
But I needed a *.deb file, so here was right the @creaktive, I had to search for a *.deb file link.
Thanks to all for the answers!
Answer
A redirect of standard output into arbitrary file name always works. You are doing it correctly as man wget says, using -O
wget http://www.kernel.org/pub/linux/kernel/README -O foo

Indeed, you must be getting an HTML in your file (usually can be checked with man file).
[EDIT]
In your case client is receiving 302 Found (you can check it with curl -v URL).
The following curl does the trick by respecting the 3xx:
$ curl -L http://sourceforge.net/projects/sofastatistics/files/latest/download?source=files -o foo.deb

$ file foo.deb

There should be similar option for wget to tolerate HTTP redirects.
