How to rename the downloaded file with wget?

Question

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
<         


        

Answer 1

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
--2013-01-13 18:59:44--  http://www.kernel.org/pub/linux/kernel/README
Resolving www.kernel.org... 149.20.4.69, 149.20.20.133
Connecting to www.kernel.org|149.20.4.69|:80... connected.

100%[======================================================================================================================================>] 12,056      --.-K/s   in 0.003s

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

  0     0    0     0    0     0      0      0 --:--:--  0:00:02 --:--:--     0
100 2035k  100 2035k    0     0   390k      0  0:00:05  0:00:05 --:--:-- 1541k
$ 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.
