Hi -

Right now I have a problem with my crontab.

Here is the crontab file.

I keep getting these emails

root: not found

And the log file /var/log/crontab

Jun 17 00:20:00 silver-fox /usr/sbin/cron[246]: (root) CMD
Jun 17 00:20:00 silver-fox /usr/sbin/cron[247]: (root) CMD
Jun 17 00:20:23 silver-fox crontab[253]: (root) LIST (root)

So I see that ^I and root and what I am assuming is the CMD, which it really
should not be. If I am right the cron is trying to run /usr/libexec/atrun as
user root and not part of the command. I just don't get it. I have tried to
edit the crontab with crontab -e and even copied a new file over from
/usr/src/etc/crontab and then did crontab crontab to get updated. I'm lost.

It looks like you've copied the system crontab to roots crontab. It appears as though the system is trying to run the command "root /usr/libexec/atrun", which doesn't exist, while at the same time the system crontab is running normally (thus the messages in your crontab log). The system crontab has the "user" field in it, so it can run commands as any user. Each user's crontab is missing that field (even root's) because it would be a security breach to allow users to change the user that their cronjobs ran under. To edit the system crontab, use your favorite editor to edit /etc/crontab. This file should have 7 fields. The 6th is the user to run the command as. To edit root's crontab, log in as root and enter 'crontab -e'. This crontab should only have 6 fields and all commands always run as root. root's crontab is treated just like any other user's. For more information, see the various man pages on crontabs.
