Hello,
Urgent! I need to build a UNIX script that calls a PL/SQL every 30 seconds.
I can not use crontab to realize it, right? Then how can I fulfil? I have no much knowledge about UNIX script.

If you have a wrapper script with a loop and a sleep function you can spawn another process whenever you like.
i=0 while [ $i -lt 10000 ] ; do if [ `date +%S` -eq 0 -o `date +%S` -eg 30 ] ; then echo "do something" fi sleep 1 ((i=i+1)) done

Thanks David,
It seems functional. Thanks so much.
Here I'd like to know a little more. Your code only runs 10000 times, right? If I want the shell command to run repeated, is it a good way to combine with using crontab file?
