[rhn-users] syntax of my cronjob

[Kvetch]

Hello, I am having some issues with a script I have in my cron. I have a 
script that when it runs I would like to write out its output to the screen 
into a file and then mail the contents of that file to myself. The script 
takes about 2-5 minutes to finish processing.

If I run the following a couple times I notice that it is actually emailing 
the contents of the file before it finishes running the job and if the job 
had run earlier then it sends me the contents of the file the last time it 
ran.
#/opt/app/cron/runjob.sh > /opt/app/cron/runjob.out |cat 
/opt/app/cron/runjob.out | mail -s "Job Output" me at gmail.com

So I added a rm command in the beginning thinking that this would help. But 
it now sends out a blank email.
0 5 * * * rm /opt/app/cron/runjob.out | /opt/app/cron/runjob.sh > 
/opt/app/cron/runjob.out |cat /opt/app/cron/runjob.out | mail -s "Job 
Output" me at gmail.com

So basically how can I write out the output of the script and email it also 
while making sure it emails the contents of the file after the job has been 
run? I need it to write out the file so I have access to it for the entire 
day until the next time the cronjob runs.
I know my syntax is really poor so if anyone has any thoughts on how to 
clean it up I would appreciate it.

Thanks,
Nick
