Script not running properly when run from Crontab
Hi

I am a novice Linux/Perl user and am struggling to overcome what I am sure is a simple problem.

I am using a perl program to create a shell script daily containing between 10 and 30 "at -f" commands for the same day. Then I change the file attributes to allow the file to be executed. When I run this script from the terminal it works fine and all the "at" commands are set up, however when I run it as a crontab event it only sets up the first 8 every time. Is there a simple explanation for this? If not, is there a way I can force the script to open and execute in a terminal session when invoked from crontab?

I am running the Hardy Heron version of Ubuntu.

Thanks for any help you can give me.

Simon

I don't know your version of Linux, but there is a maximum size to the cron job queue. In similar circumstances I staggered the at jobs with sleep statements.
