I think you can make cronjob run on every Friday, and in your script
 check if date is 2nd (3rd) Friday.

OTOH, if you specify days and day of week, I think they will both match,
 which is not what you want.

I found this with google:
<http://www.computing.net/unix/wwwboard/forum/2731.html>

Which leads to something along these lines ...

day=`date +%d`

if [ $day -ge 8 -o $day -le 14 ]; then

    echo <javascript:void(0)> '2nd Friday'

   # do F2

elif [ $day -ge 15 -o $day -le 21 ]; then

    echo <javascript:void(0)> '3rd Friday'

   # do F3
fi
