CRON JOB Problem

[ndurjoy3002]

hi,

I am using 2.6.32-21-server #32-Ubuntu SMP.
I am trying to mail to my root account everyday logwatch. So i write to crontab
fro my root user

cron -l

output

41 20 * * * root run-parts /etc/cron.daily

and then put an executable under /etc/cron.daily folder.

content of executable

#!/bin/bash

/usr/sbin/logwatch --range yesterday --mailto my email id


But the cron scheduler mail at right time but with no content of logwatch. I think i does no run that executable. My executable is ok cause i can run it from command line and if i run "/usr/sbin/logwatch --range yesterday --mailto my email id command then it also mail. I also tried to put shell script then also no effect.

So can anybody help me what is the problem. I am giving the mail sent my cron sceduler below.

please help me to sort it out

have you tried just
41 20 * * * run-parts /etc/cron.daily
?

I don't know what you meant to achieve with "root run-parts". But you need to run the script as root, put the above on the root cron

$ sudo crontab -e

See also man 5 crontab

Hope it helps

Thanks Ptkobe for your post.
My problem solved in different way what i do i just write the command directly in my root crontab.

# crontab -e
# 05 00 * * * /usr/sbin/logwatch --range yesterday --mailto root@sibl-bd.com

and my problem solved. but what i want to know that what is the purpose of cron.daily folder. and how can i use it.

man cron only has a small reference to the /etc/cron.{daily,weekly,monthly} directories

https://help.ubuntu.com/community/CronHowto says a bit more

But the idea is fairly simple. You put a script there and it runs once a day, no?

It seems the script name may not contain a period (.). Could that be it?

Also
"Although cron requires that each entry in a crontab end in a newline character, neither the crontab command
nor the cron daemon will detect this error. Instead, the crontab will appear to load normally. However, the
command will never run. The best choice is to ensure that your crontab has a blank line at the end."
