Question : How do I edit a crontab outside of an editor?

Hi,

I want to deinstall and reinstall a crontab using a PHP script. $ man crontab mentions that editing of the crontab files directly is discouraged - is there a way to add lines to the crontab via the shell, instead of within the editor that is loaded upon executing with -e?

Something like: crontab -e -u root < * * * * * /command ?

Or is it safe to edit the crontab file directly?

Thanks
