Hi.

See man at. Creating a script with at allows you to schedule a job at a specific time. In the script when the job finishes, schedule the next execution.

Experiment with, say, 5 minute intervals to see how it might work for a daily execution ... cheers, drl

If you have the GNU date command, try
Code:
sleep $(($(date +%s -d"6:30 tomorrow") - $(date +%s)))
