URL='http://10.0.0.1' MIME='image/jpeg'   
 bash -c 'wget -q -O - "$URL/wiki/index.php?title=Special:MIMESearch&mime;=$MIME&limit;=500&offset;=0"

If you use Ubuntu, the full circle magazine is a great resource, go check it out. For example from the latest issue I’ve learned that I should install vim-nox on my servers if I want to upgrade ...
