https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=210538 Bug ID: 210538 Summary: [feature request] limit number of running instances in crontab Product: Base System Version: 10.2-STABLE Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: bin Assignee: freebsd-bugs@FreeBSD.org Reporter: mi@FreeBSD.org Ensuring, only a single instance of a cron-job is running is a very common requirement. Currently, our cron does not offer any help there -- people must implement it in their programs/scripts. And it is usually done poorly... anacron has a special switch -- `-s' -- which would ensure, _every_ job runs no more than one instance at any time. I think, we can do better by expanding crontab's syntax to allow specifying the maximum number of each job's instances allowed. I'd be happy to implement it, if the idea seems reasonable to someone with a src-commit bit... -- You are receiving this mail because: You are the assignee for the bug.
