Good point! Both of them. That would make a not-so-quick but better hack. Append a timestamp and a start note / end note with exit code to a log file, to have a history. You might also send an email in case of a crash. Let's see ...

#!/bin/sh while true do start_your_program RC=$? # return code if [ $RC -gt 0 ] then date >> /var/log/your_log_file echo "ABNORMAL program termination, rc = $RC" >> /var/log/your_log +_file echo "terminated at `date`, restarting | mail -s "Problem with zzz +" root sleep xxx else date >> /var/log/your_log_file echo "Normal program termination, rc = $RC" >> /var/log/your_log_f +ile sleep yyy fi done
You can do further checking on the exit code as Mark suggested and act diffently according to the exit code (see case statement in your shell manual).
