Is it possible to make cron receive it's instructions from the output of a shell script instead of reading a static file?
I'm trying to manage crontabs across a bunch of machines and maintaining separate crontab files for each machine is a chore. I'd like cron to instead run a shell script that prints out crontab lines for each job based on whether a given machine is assigned to that job. Can I do this?
P.S.- I've seen some suggest Puppet/Chef/etc. for this purpose, but I think that's overkill for handling just this one problem.
