The only way i know to do this is to set up your cron for every Saturday. The cron then calls a script which checks if it is the second saturday of the month.
How does the script work ? Well, the second saturday must lie between the 8th and the 14th

So you script needs to say something like :-

day=`date +%d`
If $day >7 and <15 then .... execute your next script
else do nothing.

Post back if you need further help with the script

if you run the job every saturday then you can calculate the week in your script with something like:

cal | awk '{s=&quot; &quot;$0&quot; &quot;}s~/ '`date +%d|sed s/^0\*//`' /{print NR-2}'

then if week number is 1 first saturday if is 2 second saturday and so one ..

Hope it helps,
