Need 20+ php scripts to run via cron job, to run every 4 hours at 2 mn's apart each?

2 */4 * * *
4 */4 * * *
6 */4 * * *

Will these run at their marked mn of every 4 hours, or will they run every 2,4,6 mn's for the whole hour?

 

the first one will run on the second minute, every 6 hours
the second one will run on the fourth minute, every 6 hours
the third one will run on the sixth minute, every 6 hours

 

ok thanks, I deleted the cron job I had problems with last wek, but it looked like it ran every minute of that requested hour. I think I just messed up somewhere.
