Hi,

I am working on solaris 9 and 9.2.0 database.I am trying to add a script to be run every day using cron.The script that I want to run is in $SCRIPTS location and when I add the cronjob as below:
crontab -e

0 3 * * 1-5
/telk/oracle/admin/scripts/DbMonitor/clean_exp.sh>/tmp/clean_exp.log 2>/dev/null

and I did ZZ (to save)

I dont see the job I added when I do crontab -e or crontab -l.

Could somebody help me?

Hi Taj,

Thats exactly what I did. .sh has priveleges. I think there is something going on the server side. Thanks for your reply.

Including " 2>/dev/null " in a crontab entry BEFORE the script is debugged is not a wise course of action.
IMO, I always start with " 1> /tmp/capture.log 2>&1", until I know all is well.
Without feedback, you are trying to troubleshoot in the dark with your eyes closed.

File handle #1 is Standard out (STDOUT)
File handle #2 is Standard Error (STDERR)
2>/dev/null send error messages into the bit bucket.
