timerDaily 05:59 1 60 /MyAlias

alias MyAlias {
<my commands here>
timerDaily 05:59 1 60 /MyAlias
}

(the delay of 60 seconds is so that you don't automatically retrigger when you run the alias - perhaps the more experienced here can advise if this is necessary)

is one option or ...

timerDaily 06:00 0 $calc(60*60*24) /YourCommand

is another option (the $calc is there just to demonstrate the number of seconds in a 24 hour period).

Cheers,
