问题
Need some advice, I'm after a decent process/task manager for Ubuntu.
Basically I have a few scripts/programs which I want to run as long running processes, but I want to shut them down at various periods (say over the weekend or every day for a few hours). During the time that the process needs to be up and crashes, I would like it so that the task scheduler will automatically restart the process.
SO for example, I want to run program X between 9:00-17:00 every day. If the process is still running it should be killed at 17:00. If the process crashes between 9AM and 5PM then the process should be automatically restarted.
Are there any easy to use tools which can do this? I would like to avoid having to manage PID files and having cron jobs which do the start and stop...
Any thing anyone recommends? Any advice appreciated!
Cheers.

I do not know if a tool exists for this, but except if you have many interactive tasks, it really does not a that big issue to manage for a few jobs :
1) You can start your cronjobs whenever you like thanks to the crontab,
2) You can insert a "commit suicide" within these scripts under a time condition for example.
# your script doing things
# Then it commit suicide
if [ your_condition ];then
kill $$
fi
Please note that if you want to allow users login only at certain periods of time, then it's a different question.
