CronInstead of minute, hour, day, month or day of week it's also possible to specify a *. A * represents all possible values for that position (e.g. a * on 2nd position is the same as specifying all the possible values for hour) It's also possible to specify several values separated by commas: e.g. if you want a command to be executed every 10th minute so you can specify 0,10,20,30,40,50 for minu
