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!


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 
foo.deb: gzip compressed data, was "sofastats-1.3.1.tar", last modified: Thu Jan 10 00:30:44 2013, max compression

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


If you were to do the same download from a web browser, and you notice the browser actually naming the file correctly, you can use the --content-disposition option to give wget the same behaviour:

wget --content-disposition http://sourceforge.net/projects/sofastatistics/files/latest/download?source=dlp

My Debian man page reports this as an 'experimental' feature but I cant recall it not working for me:

       --content-disposition
           If this is set to on, experimental (not fully-functional) support for "Content-Disposition" headers is enabled. This can currently result in extra round-trips to the server
           for a "HEAD" request, and is known to suffer from a few bugs, which is why it is not currently enabled by default.

           This option is useful for some file-downloading CGI programs that use "Content-Disposition" headers to describe what the name of a downloaded file should be.
