Thread: Questions about CRON

ok, here's plan:

want add , specific or not cronjobs through script* (when 'specific' mean specify when , when 'or not' mean job may have * values in month or day example)

*no crontab -e allowed

what's right way it?
these things don't feel comfortable with:
a) when 'specific' job done cron doesn't delete afterwards, how can solved?

b) when want add new cronjob have check if there cronjobs, if write temp file crontab -l output , append there new job. reinstall using 'crontab temp_file', quite right?

c) what's right way remove 'or not' action? crontab -r removes last action, guess in order delete specific action have write somewhere crontab -l, edit file sed or , re-install it?


answering these (first of all) clean things out
