Very Interesting Command, i never came by this before. But can you correct me on this if i'm wrong.

The "at command" does not have an every day feature, so away around this is by having it invoke itself in a script.

# my.daily runs every day
at now tomorrow < my.daily
daily-processing

So here, my.daily is a script that is written like this

at now tomorrow

Then when the user runs there script and in the parameters they have the keyword "tomorrow"
So this insures tomorrow is always recurring.

so an example of this would be:

$ at 1145am now tomorrow < my.daily
at> cc -o foo foo.c
at> ^D

Did i get this right?

Thanks.

But then again, you could find yourself not in at.allow or in at.deny (I dont know for linux...)

And Phi01, yes you got it right - you can use at in a way the submitted job reschedules itself...
