Here are the entries in the crontab. I think she is using the second approach, how do I check?
10 3 * * * /usr/sbin/logadm
15 3 * * 0 /usr/lib/fs/nfs/nfsfind
1 2 * * * [ -x /usr/sbin/rtc ] && /usr/sbin/rtc -c > /dev/null 2>&1
30 3 * * * [ -x /usr/lib/gss/gsscred_clean

# Start Apache in case it stops
0,10,20,30,40,50 * * * * /usr/local/etc/start_apach
# Switch over the Apache logs

Hi,
if you want to list root crontab jobs:
As root run
crontab -l > mycrontab
you may edit (e.g. using vi) the file mycrontab to change the way crontab jobs are run
e.g. to change
* * * * * /usr/bin/ls
to
* * * * * /usr/bin/ls | /usr/bin/mail -s "ls output" youremailaddress
Then you may resubmit the crontab jobs
crontab mycrontab
if you want to list root crontab jobs:
As root run
crontab -l > mycrontab
you may edit (e.g. using vi) the file mycrontab to change the way crontab jobs are run
e.g. to change
* * * * * /usr/bin/ls

Then you may resubmit the crontab jobs
crontab mycrontab

If I am root, can I just use crontab -e and modify the cronjob?
This admin is gone so, I want to have the root email changed to my email, how do I do that?
Thanks

Hi,
Although you can use the -e option to edit crontab jobs directly, but it is better to keep a copy of the current jobs schedules in a file and edit the file then resubmit. Many administrators do mistakes while editing directly (and hence loose what what scheduled).
Now, coming to your question on how to send emails to you (not root).
There are many ways:
1- for each scheduled job just follow the example where you pipe output and errors to mail. I will take simple example and you can do similar
* * * * * /usr/bin/ls 2>&1 | mail -s "ls output" youremailaddress
2- Or you may edit each script scheduled and redirect output and error (of commands run in the script) to a file then email the file to your self. I will repeat the example here:
* * * * * /path/to/myscript
where myscript has
/usr/bin/ls > /path/to/output.log 2>&1
/usr/bin/mail -s "ls output" youremailaddress < /path/to/output.log
3- You may forward all emails coming to root to your self (All, which could be troublesome!) by creating /.forward file and add your email address to it. Please see
man forward
for more details

Thanks for all the help!!!!
If the crontab job itself is not sending emails, then the default behavior of crontab is to capture job output and mail it to the user running the job.
So, if root is the user that run the job, (s)he will continue to receive the emails. You may modify the jobs to send output to your email by piping the output to your mail command that send it to you.
e.g.
If your crontab job run something similar to
* * * * * /usr/bin/ls
then you may change it to
* * * * * /usr/bin/ls | /usr/bin/mail -s "ls output" youremailaddress
a more proper way is to redirect stdout & stderr to a file then mail the file
e.g.
* * * * * /path/to/myscript
where myscript has
/usr/bin/ls > /path/to/output.log 2>&1
/usr/bin/mail -s "ls output" youremailaddress < /path/to/output.log
