Crontab schedule

Hi,

I have a script which will query the DB and added to crontab at 1,2,6,7 AM everyday and sends a email if count is 0.

Now the problem is, if crontab is disabled it doesn't sends a mail.
Please tell me how can I handle this situation in the script.

How could a script respond to the fact of not being run because of crontab being disabled? It can't ...

What you could do, though: chance the mail output to "one mail per run" (read: every run), then tell the recipient when to expect those mails and that "no mail, no go(od)".

if cron is disabled, u can launch the script after sometime probably via using at..
