I have a script that checks a folder for zip files than moves them to a different folder. I want to check every 5 maybe 10 seconds and since cron is setup to run at least a 1 minute increment I'm not sure how to do that time check as probably a loop within the script.

One other thing is once the time check is in the script how would a cron job be setup to run this script? Once the script is running cron doesn't need to run it again, is there a feature to check if it's running and if it's not then run it?

find /export/xxxshare -name "*.zip" -exec mv {} /export/store \;

This sounds like a job for incrontab rather than crontab, I use incrontab for lots of things and it works great.

Two more good inotify/incron introductions here and here.

Decided running a cronjob every minute would be sufficient.
