How do I remove crontab data I set up?

Hi there,

I recently edited my crontab so that my external hard drive would automatically mount and unmount once a night for backup purposes. I learnt how to do this from this site:

http://hints.macworld.com/article.php?story=20070313192221659

Now I don't need my external hard drive to automatically mount and unmount anymore and I pretty much want to remove the data from the crontab. I'm not sure if it's just a matter of going into it by typing crontab -e and removing the text or if I actually need to delete a file within Mac OS X or something else.

Thanks for your time and I hope to hear from somebody soon.

Regards,

Daniel

Terminal and Unix oriented questions are best asked in the Mac OS X Technologies > Unix Forum

As you guessed, you just use


crontab -e

and remove your entry.

When you exit the editor, crontab will update the daemon that runs cron jobs.

Hi Bob,

Thanks for your reply. I will keep the Unix Forum in mind for next time. I've been browsing the net about how to remove the cron entry from my system and I come across crontab -r, which removes the crontab apparently. Would this be another method of doing it? Basically I'd rather reset the crontab to its default settings than me just going in and removing it manually...
