AIX

I have a little difficulty with the "at command". I use it to run hourly for daytime reports. I use korn shell scripting. It runs normal at daytime, but when at night it dies. So I have to start up in the morning again. The script is fine to me. I was thinking to switch to cron job, but I have a lot of stuf on my cron job already.
My question, Do you know why it dies ?? What might cause it to die???
Thanks

Without seeing the script or at command, my initial response would be that your script, written in Korn shell, is being executed using Bourne shell as defaulted by the at(1) command. There should be an option to specify use of ksh.

Just a thought...You must be doing something differently during the day than at night.

As for loading up the crontab, don't sweat it. Unless sequentially dependent, separate your tasks and stagger them during the hour. Using at(1) does not lighten the load on cron. The same daemon is used to fire off both.
