Cloning Cron Job!

Hi,
How do i clone an existing cronjob?

Step by Step instructions will be helpful.

Thanks

What do you mean 'duplicate'? You want it to run the same job twice in a row?

no i want to take an existing cron job from production and clone it to use different entries for another interface.

Different how? What does the job look like now, and what should it look like in new entries? Will these new entries be in the same crontab or a different one?

You can get the current crontab for your user with crontab -l, and completely replace your crontab with crontab < filename.

Please show before and after examples making it clear whether there is more than one computer.
