I doubt it, based on the results of this crontab on EL7: 51 13 * * * echo start 1 ; sleep 2m ; echo end 1 51 13 * * * echo start 2 ; sleep 2m ; echo end 2 At 13:51, nothing appeared in my mail file. Two minutes later, two different messages appeared, each with the expected "echo" outputs. Thus, they must have run in parallel.
