will crontab start a job if the previous execution is running?

[foampile]

in the simplest configuration format, i was wondering if crontab will start a job if the previous execution is still running?

thanks

Yes. crontab just exec's the job. If you don't want that behavior you should write your task to determine if another copy is already running. A pid file is the traditional technique.

Dear foampile.

Just tried with a script which sleeps a bit.
The answer appears to be yes

Good luck

yeah, that's what i thought
