https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D210538 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 mu= st implement it in their programs/scripts. And it is usually done poorly... anacron has a special switch -- `-s' -- which would ensure, _every_ job run= s 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... --=20 You are receiving this mail because: You are the assignee for the bug.=
