cron/sendmail problem

I was hoping someone could help me out here. Here is the relevant
info:

My crontab:
root@KnoppixServer:~# crontab -l
54 5 1,7,14,21,28,30 * * /root/cronjobs

The file it is calling:
root@KnoppixServer:~# cat /root/cronjobs
echo Server Status Update > statusMail
echo >> statusMail
date >> statusMail
echo >> statusMail
du -ch --max-depth=2 /mnt/storage/ | egrep -i
'([0-9]{3,}(\.[0-9]+)?M|[0-9]+(\.[0-9]+)?G)' >> statusMail
echo >> statusMail
free -m >> statusMail
echo >> statusMail
df -h >> statusMail
echo >> statusMail
uptime >> statusMail
cat statusMail | sendmail [email]myrealaddress@somewhere.zzz[/email]





Now, if I run the script manually by typing /root/cronjobs, it works.
the file statusMail is created, and filled up with all the cool info.
Then, cat pipes the text to an e-mail, which I receive successfully.

But, if the cron job runs, I get no e-mail. The file IS created,
which I've verified by the timestamp of the statusMail file.

By the way, that long line (which may have wrapped here in the
newsgroup),
is a regular expression which causes only lines of over 100mb from the
output of
"df -h" to display. Nice for finding bloat on a fileserver.

Thanks in advance,
Shawn

It's me again. I solved the problem by using the command "mail",
instead of "sendmail". It works fine with "cat". I still don't know
why sendmail doesn't work, but it doesn't work with either sendmail or
postfix (which has a "sendmail" clone included).

Also, there's a typo in my post regarding that regular expression, I
should have typed "du" instead of "df", but I'm sure you got the
point.

instead of mail or sendmail ... use /usr/sbin/sendmail

Thanks
