Hi!
You should not put entries in /etc/crontab. Instead use 'crontab -l'
to list your crontab entries. If logged in as root, it will show
root's entries. If logged in as crnholio, it will show crnholio's en-
tries.
Using 'crontab -e' you can edit your own entries with an editor. Use
'setenv EDITOR "your favourite editor"' to change from vi to "your
favourite editor".
Put the following in your crontab:
45 0 * * * program
0 6 * * * killall -9 program
I'm not sure this will help, but it's the correct way to do it. :-)
Best regards,
Paul
