Script for Scheduling a process

[arjagadish]

I need a shell script to execute process in every 30 secs.

What command should I use and syntax. An example would be a great help for me.

cron will allow to to execute every minute, but you can't get down to 30 secs. For this see the man pages for crontab and cron

To run every 30 secs you could have a wrapper script something like ...

while true
do
  run script here
  sleep 30
done

... could be a real drain on resources though!
