UNIX for Dummies Questions & Answers

This is regarding my cron job. My cron entry
30 * * * 1-5,0 /work1/informix/sample/script1.sh
31 * * * 1-5,0 /work1/informix/sample/script2.sh

Every 30 mins script1.sh is run. (mon thru friday and sunday)
Every 30 mins script2.sh is run. (mon thru friday and sunday)

This is based on the thread
(https://www.unix.com/unix-dummies-que...ttachment.html). Thanks to folks who helped me out. The system guys started the cron and sendmail daemon and so i could get the mailx work.

script1.sh
onstat -d > /work1/informix/sample/track.txt
onstat -l >> /work1/informix/sample/track.txt

script2.sh
mailx -s "Informix Database Status & LogFile Status" 'name1@mydomain.com, name2@mydomain.com' < /work1/informix/sample/track.txt
I did execute the script2 manually from command line and it worked.

After monitoring:
Issue1:
I found that the cron job does execute, but when i check the file track.txt in the directory its generated every 1 hour. I have set the cron job for every 30 mins. I would require the cron job to do the work every 30 mins and not at 1 hour.

Issue2:
Any reason for the error:
But when cron job executed after 1 hour, i got the following in /var/mail/informix file

Your "cron" job on sun-350 (machine name: sun-350)
/work1/informix/sample/script2.sh
produced the following output:
/work1/informix/sample/script2.sh: track.txt: cannot open

So now i have included the full path and in script2.sh
(earlier my entry was
mailx -s "Informix Database Status & LogFile Status" 'name1@mydomain.com, name2@mydomain.com' < track.txt)

Iam missing something, do point me to correct direction!

thanks

Set the cron entry 0,30 * * * 1-5,0 and it will in fact run every half hour at the moment you have to run on the half of every hour.

Where is track.txt? This I believe is your problem give it the full pathname to track.txt.

Johnf - thanks so much. First, I did give a try (before i saw your reply), yes i did figure out the path of track.txt and included the full path, and it worked.
Next - the cron job did work finally. But this time, i set it just once a day and it works fine.
thanks so much for the input.
