cron job issue..i hav read the basic threads already...

hi friends

well m facing a different sort of issue in my cron.
i hav set job like this

30 09 * * 1 /bin/backup14M
01 14 * * 1 /bin/backup14N
20 18 * * 1 /bin/backup14E

that is for every Monday at three different times.
but, first job executes well, later ones do not. I checked my scrip result at 14:05 hrs, and it was not executed, i change the job to 14:08 and it executed well at the specified time, then checked at 18:21 hrs for the output, again it didnt execute, and i changed the time to few more minutes and it executed at that time. All i noticed is, that if i change the time to few minutes, it executes, but it do not execute for big intervals.
Can anybody tell the problem and the respective solution

Mentionable:- I hav the checked the basic cron forums, so find my issue lil different from the mentioned.. Using centOS 5.3 system.

thanks in advance

I'm not sure what you mean by "big intervals". Can you explain.

Also have you set the HOME, SHELL, and MAILTO... just to to make sure.

See if you get any mail after the event time has passed....

hi JP

from big intervals i mean, like wen i change the schedule with just minutes, it do work, but if the next schedule is after few hours, as i mentioned in my crontab example, it do not run the script

And, m sorry m new to Cron as well as Linux, and m not sure how to set the rest of the attirbutes, and wat exactly do they require for..

and if these attributes do effect, then i believe the cron job shud not work for the rest of jobs as well, that i run if i change the same to minutes.

restart cron

Did you restart crontab after scheduling it?

# /etc/init.d/crond stop
# /etc/init.d/crond start

Do a

man -s 5 crontab

It will give you the meaning of the vars and show examples of a crontab using them.

You shouldn't have to restart crond. It automatically checks every minute to see if anything has been modified. If yes, then it reloads everything.

And make sure you are using crontab -e to modify the crontab..
