[Bug-wget] Help request to download data from http

[Pedro LL]

Hello,
I am a beginner user of wget. I wanted to use it to download data from an 
specific website into my mac using unix but I have been unable after many many 
attempts.
I was typing in the terminal:
 wget -q -O - http://sodaserver.tamu.edu/assim/SODA_2.2.4/ | grep _2009 | wget 
-N --wait=0.5 --random-wait --force-html -i -
but it returns this:-: Cannot resolve incomplete link /icons/unknown.gif.-: 
Cannot resolve incomplete link SODA_2.2.4_200901.cdf.-: Cannot resolve 
incomplete link /icons/unknown.gif.-: Cannot resolve incomplete link

I was wondering if someone could give me a hand with this,
Many thanks in advance,Pedro
