Agora vi também, a opção -O do wget.

-O file
       --output-document=file
           The documents will not be written to the appropriate files, but
all will be concatenated together and written to file.  If - is
           used as file, documents will be printed to standard output,
disabling link conversion.  (Use ./- to print to a file literally
           named -.)

           Use of -O is not intended to mean simply "use the name file
instead of the one in the URL;" rather, it is analogous to shell
           redirection: wget -O file http://foo is intended to work like
wget -O - http://foo > file; file will be truncated immediately,
           and all downloaded content will be written there.

           For this reason, -N (for timestamp-checking) is not supported in
combination with -O: since file is always newly created, it
           will always have a very new timestamp. A warning will be issued
if this combination is used.

           Similarly, using -r or -p with -O may not work as you expect:
Wget won't just download the first file to file and then download
           the rest to their normal names: all downloaded content will be
placed in file. This was disabled in version 1.11, but has been
           reinstated (with a warning) in 1.11.2, as there are some cases
where this behavior can actually have some use.

           Note that a combination with -k is only permitted when
downloading a single document, as in that case it will just convert all
           relative URIs to external ones; -k makes no sense for multiple
URIs when they're all being downloaded to a single file.


Adonai, depois, caso consiga uma solução para o seu problema, poste-a para
pesquisa futura no histórica da lista.
