Hi David,

curl --user-agent "Mozilla/5.0 (X11; Linux x86_64; rv:25.0) 
Gecko/20100101 Firefox/25.0" -I 
'http://www.overlooksoft.com/packages/download?plat=lx64&ext=rpm' 2>&1 | 
grep -i "Content-Disposition" | awk -F '"' '{print $2}'

overlook-fing-2.2.rpm

Did the trick!

Thank you for helping me with this.
